Sample records for anatomists

  1. [Anatomist, pathologist and philanthropist]. (United States)

    Laerum, O D


    Fredrik Georg Gade (1855-1933) was born in Bergen as the eldest son of a merchant and politician. He graduated from the University of Oslo in 1880. After clinical residency and training in anatomy and pathology at the National Hospital in Oslo, he worked in several of the most outstanding medical research institutions in Continental Europe, including the institutes of Robert Koch and Carl Friedländer in Berlin, Carl Weigert in Frankfurt, the pathologists and anatomists Victor Cornil, Louis-Antoine Ranvier and Louis Charles Malassez in Paris. Gade was associate professor (prosector) of anatomy in Oslo from 1897 to 1906 and also the editor of the Norwegian Medical Journal (Norsk Magazin for Laegevidenskaben). He was also one of the pioneers of cancer statistics in Norway. In addition to his scientific publications, he wrote extensively on political and cultural issues. Struck by serious illness he donated most of his family fortune to establish an institute for pathology in his home town Bergen, which opened in 1912 under the name Dr. med. F.G. Gades Pathologiske institutt. It later became one of the pillars of the Medical Faculty when the University of Bergen was established in 1946 (now: The Gade Institute, University of Bergen).

  2. Ask an anatomist: Identifying global trends, topics and themes of academic anatomists using twitter. (United States)

    Marsland, Madeleine J; Lazarus, Michelle D


    Social media (SoMe) is increasingly used in higher education (HE) to access knowledge and enable global communication. The SoMe platform Twitter ® is particularly beneficial in these contexts because it is readily accessible, easily searchable (via hashtags) and global. Given these advantages, the twitter platform @AskAnatomist was created to foster a global weekly tweet chat, where students and academics can ask and address anatomy-related questions. The aim of this study was to identify themes arising in the early stages of the @AskAnatomy Twitter community to gain insights into current needs/key areas for academic anatomists, students, and other followers. A qualitative analysis of tweets including the hashtag #AnatQ, (the associated @AskAnatomist hashtag), was undertaken to achieve this aim. Thematic analysis revealed three core themes arising in the formative stages of the @AskAnatomist Twitter site: (1) anatomical education modalities, (2) specific anatomy content, and (3) research motivations. These themes reveal controversies within the field of anatomical sciences, areas for potential education resource improvement and research, as well as the humor of anatomists. Though the original intent of the @AskAnatomist site was to engage the general public in anatomy content and knowledge, tweet analysis suggests that academic anatomists were the primary active "tweeters". Interestingly, this analysis reveals that the @AskAnatomist site progressed into a web-based community of practice (CoP), suggesting an additional benefit of SoMe communities in the field of anatomy. © 2017 American Association of Anatomists.

  3. Greek anatomist herophilus: the father of anatomy


    Bay, Noel Si-Yang; Bay, Boon-Huat


    One of the most stirring controversies in the history of Anatomy is that Herophilus, an ancient Greek anatomist and his younger contemporary, Erasistratus, were accused of performing vivisections of living humans. However, this does not detract from the fact that Herophilus has made phenomenal anatomical observations of the human body which have contributed significantly towards the understanding of the brain, eye, liver, reproductive organs and nervous system. It is notable that he was the f...

  4. James Drake (1667-1707): Anatomist and political activist. (United States)

    Tubbs, R Shane; Rompala, Olivia; Verma, Ketan; Malakpour, Mehran; Shoja, Mohammadali M; Mortazavi, Martin M; Loukas, Marios


    James Drake (1667-1707) was a renowned physician, anatomist, and writer whose name was recognized throughout London. He was highly involved in the politics of his time and was a well-known pamphleteer. He also delved into comedies and plays. Drake became a fellow of the Royal Society and the College of Physicians before his early death at 40 years of age. He authored one of the most deservedly popular medical treatises of his time, Anthropologia Nova, which remained a valuable resource to physicians and anatomists alike for decades. The present article reviews the contributions of this little known name in the history of anatomy. Copyright © 2011 Wiley Periodicals, Inc.

  5. The Illustrious Anatomist: Authorship, Patronage, and Illustrative Style in Anatomy Folios, 1700-1840. (United States)

    Berkowitz, Carin


    A number of anatomists working in the period 1700-1840 used expensive illustrated books to depict their greatest scientific work, establish priority of discovery for posterity, and enlist patrons. These anatomists drew on the grand traditions of anatomical illustration and asserted their right to a place within that history. But with artists mediating the expression of anatomists' vision, it was important that an anatomist assert his control over the illustrations commemorating his expertise. Anatomists used stylistic signatures to signal that a work was their own. Very different styles of illustration in the works of different anatomists, therefore, were made easily recognizable, and sometimes a single artist adopted notably different styles for different anatomists who employed him. Style became a marker of authorship, identifiable with the anatomist, even when he employed an artist to do the drawing and engraving, and it was also an important method of appealing to patrons.

  6. Frequency in Usage of Terminologia Anatomica Terms by Clinical Anatomists

    Directory of Open Access Journals (Sweden)

    Bradford D. Martin


    Full Text Available Almost 16 years since the publishing of Terminologia Anatomica (TA by the Federative Committee on Anatomical Terminology (FCAT, there has yet to be a unified adoption of TA-recommended anatomical terms by anatomists. A survey was sent to members of the American Association of Clinical Anatomists (AACA to determine the frequency of TA term usage. Most respondents (70.3% received their terminal degrees in anatomy, with 23.4% in clinical and anthropological areas. Academically ranked, most respondents were professors (38.4% and most were from North America (81.1%. Almost 40% of respondents were textbook authors. Overall results indicate that the TA preferred term had the highest frequency of usage in only 53% of the anatomical structures/features surveyed. Compliance with TA preferred terms ranged from 98.2% to 3.6% usage. Almost 25% of AACA anatomists were not familiar with the FCAT and over 75% were concerned about synonymity in anatomical terminology. Data demonstrates that clinical anatomists of the AACA are not consistent in how they use anatomical terminology, as well as how they conform to TA terminology.

  7. Jean Leo Testut (1849-1925): anatomist and anthropologist


    Reverón, Rafael Romero


    Leo Testut (1849–1925), professor of human anatomy of the Faculty of Medicine of Lyon, wrote more than 90 publicationson anatomy, anthropology and history, the most outstanding of which was his treatise on human anatomy published in1887. He founded and directed the International Journal of Anatomy and Histology. He was a member of the FrenchAcademy of Medicine and president of the World Association of Anatomists

  8. Selected anatomists: at the boundary of contemporary ethics. (United States)

    Arango, Dillon; Greiffenstein, Patrick; O'Leary, James Patrick


    Fascination with the interworkings of the human body has permeated scientific discovery for eons. Materials for dissection proved problematic for anatomists. Andreas Vesalius solved his dilemma by visiting local gallows where criminals had been executed. Eduard Pernkopf has been alleged to have taken some of his materials from victims of the Holocaust. Even today, executed criminals have served as subjects for anatomical educational purposes. These circumstances are explored and the contemporary ethics of each are compared.

  9. Using and respecting the dead human body: an anatomist's perspective. (United States)

    Jones, D Gareth


    In his stimulating article enquiring into what the living owe the dead, Wilkinson (2013, Clin. Anat. DOI: 10.1002/ca.22263) sought to unpack a range of ethical questions of considerable interest to anatomists. In this, he looked closely at the extent to which we are or are not to respect all the prior wishes of the deceased, and the implications of this for the role of the family in providing consent, the use of unclaimed bodies, and the public display of bodies. Some of his conclusions challenge widely encountered views by anatomists. In this response I have re-visited these topics in an attempt to ground his arguments in the experience of anatomists, by emphasizing the many intimate connections that exist between each of these areas. The following emerge as issues for further debate. I accept that the wishes of the deceased are preeminent, so that authorities should make every effort to abide by these. This reiterates the importance of body bequests over against unclaimed bodies, and provides a context for assessing the role of family consent. This has repercussions for all activities employing dead bodies, from the dissecting room to public plastination exhibitions. In determining the extent to which the wishes of the deceased are followed the input of other interested parties is a relevant consideration. An ethical assessment of the public display of bodies needs to take into account the nature of the plastination process. © 2014 Wiley Periodicals, Inc.

  10. Jules Germain Cloquet (1790-1883)--drawing master and anatomist. (United States)

    Loukas, Marios; El-Sedfy, Abraham; Tubbs, R Shane; Wartman, Christopher


    Jules Germain Cloquet, the famed French anatomist, surgeon, and professor, may not be remembered as one of the pioneers of hernia surgery; however, his contributions have provided surgeons with detailed anatomical descriptions that have been useful in developing innovative surgical techniques. Cloquet has many eponyms associated with him, including: Cloquet's fascia, Cloquet's gland or lymph node of Cloquet, Cloquet's hernia, Cloquet's ligament, Cloquet's canal, and Cloquet's septum. A man blessed with artistic talents, Cloquet was the author of many theses, as well as anatomical volumes that were comparable to the works of other great anatomists of his time. His first thesis, entitled Recherches Anatomiques sur les Hernies de l'Abdomen, described the locations where inguinal and crural herniae are more likely to occur in terms of the cremaster muscle, the peritoneum, and the spermatic vessels. Wax sculpture training required extensive knowledge in the natural sciences, anatomy, physiology, and pathology, as were acquired by Jules Cloquet as a pupil of Achille-Cléophas Flaubert, the father of the famous French novelist Gustave Flaubert (author of Madame Bovary). Cloquet attracted many pupils with his innovative teaching style and implementation of anatomical preparations, drawings, and sketches on the black board with chalk. The legacy of this famed individual lives on today in the anatomical structures described by Cloquet.

  11. A portrait of Aristotle as an anatomist: historical article. (United States)

    Crivellato, Enrico; Ribatti, Domenico


    Aristotle is principally known as a theoretical philosopher and logician but he was also an eminent natural scientist. In particular, he should be considered probably the first anatomist in the modern sense of this term and the originator of anatomy as a special branch of knowledge. Although it seems certain that he did not perform dissections of human adult cadavers, he examined human fetal material and, above all, made systematic analysis of animal bodies. His contribution to comparative anatomy, as well as to human anatomy, was enormous. He founded the anatomical discipline on precise descriptive and scientific ground. He also coined a series of technical terms, which are still in use in the modern nomenclature. His observational skill was astounding. Although many of his physiological concepts turned out to be wrong, still his structural description of organs and body parts was often first-rank. The present study will chiefly focus on Aristotle's anatomical work and will provide only essential mention of his complex physiological and philosophical doctrine. The main purpose of this article is indeed to offer to today's anatomists a systematic account of the extraordinary achievements of this great pioneer of our discipline.

  12. Free manual of cadaver dissection modifiable by other anatomists. (United States)

    Chung, Beom Sun; Chung, Min Suk


    Even in the rapidly changing field of cadaver dissection, published guide books still play an important role in the anatomy lab. However, commercial manuals with lengthy volumes and inflexible copyrights have several limitations which can be complemented by open-source manuals. Recently, the authors have manufactured and distributed a free electronic dissection manual (, where descriptions are written concisely and images are drawn schematically. Moreover, simplified signs are employed to represent the cadaver viewing angles and manner of dissection. Based on the original files of this manual, other anatomists can revise and utilize the descriptions and figures. We expect many updated versions of our manual to be shared between students all over the world.

  13. Leonardo da Vinci: engineer, bioengineer, anatomist, and artist. (United States)

    West, John B


    Leonardo da Vinci (1452-1519) enjoys a reputation as one of the most talented people of all time in the history of science and the arts. However, little attention has been given to his contributions to physiology. One of his main interests was engineering, and he was fascinated by structural problems and the flow patterns of liquids. He also produced a large number of ingenious designs for warfare and a variety of highly original flying machines. But of particular interest to us are his contributions to bioengineering and how he used his knowledge of basic physical principles to throw light on physiological function. For example, he produced new insights into the mechanics of breathing including the action of the ribs and diaphragm. He was the first person to understand the different roles of the internal and external intercostal muscles. He had novel ideas about the airways including the mode of airflow in them. He also worked on the cardiovascular system and had a special interest in the pulmonary circulation. But, interestingly, he was not able to completely divorce his views from those of Galen, in that although he could not see pores in the interventricular septum of the heart, one of his drawings included them. Leonardo was a talented anatomist who made many striking drawings of the human body. Finally, his reputation for many people is based on his paintings including the Mona Lisa that apparently attracts more viewers than any other painting in the world.

  14. [The anatomists who started anthropology in Turkey and their contributions]. (United States)

    Uluçam, E; Gökçe, N; Başağaoğlu, J


    The Turkish Institute of Antropology was estabilished in 1925 as a unit of the Medical School of Istanbul University (Darülfünun), named the Antropology Research Center (Antropoloji Tetkikat Merkezi). It was a part of the medical faculty until 1932. After the university reform it was connected to the School of Science and in late 1935 it was transfered to the School of Languages History and Geography (Dil Tarih Coğrafya Fakültesi) in Ankara. The center started to publish "The Journal of Turkish Anthropology" with Dr. Nuretttin Ali Berkols researches in 1925. It was published in two languages, Turkish and French. The faculty members of the institute, Dr. Mouchet, Dr. Süreyya Ali and Dr. Ismail Hakki formed the editorial board of the journal. We see that from the first issue of the journal in 1925 until the special issue prepared for the XVIII. Anthropology and Prehistorical Archealogy Congress in 1939, Dr. Nurettin Ali Berkol and Dr. Mouchet were members of the administrative committee of the journal. In this article; we studied the contributions of the anatomists to the development of anthropology in Turkey.

  15. Terminologia anatomica: new terminology for the new anatomist. (United States)

    Whitmore, I


    Over many years, anatomical terminology has been the subject of much controversy and disagreement. Previously, the International Anatomical Nomenclature Committee has been responsible for the production of six editions of Nomina Anatomica. In 1989 a new committee, the Federative Committee on Anatomical Terminology (FCAT), was created by its parent body, the International Federation of Associations of Anatomists (IFAA). FCAT has worked for 9 years and published Terminologia Anatomica (TA) in 1998. FCAT's aim has been to democratize the terminology and make it the internationally accepted, living language of anatomy. The worldwide adoption of the same terminology would eliminate national differences, which were causing extreme confusion in instances where the same structure was known by several names. The new terminology is thus the result of worldwide consultation and contains Latin and equivalent English terms. It is indexed in Latin and English and contains an index of eponyms in order to find the correct non-eponymous term. The future goal of FCAT is to continue to improve the terminology-new structures are described, different terms come into use, and the terminology needs to be expanded to include terms used by clinicians for structures that currently do not appear in the list. Future versions of the terminology must accommodate the needs of all who use it, both in the clinical and scientific worlds.

  16. Can anatomists teach living anatomy using ultrasound as a teaching tool? (United States)

    Jurjus, Rosalyn A; Dimorier, Kathryn; Brown, Kirsten; Slaby, Frank; Shokoohi, Hamid; Boniface, Keith; Liu, Yiju Teresa


    The utilization of bedside ultrasound by an increasing number of medical specialties has created the need for more ultrasound exposure and teaching in medical school. Although there is a widespread support for more vertical integration of ultrasound teaching throughout the undergraduate curriculum, little is known about whether the quality of ultrasound teaching differs if performed by anatomists or clinicians. The purpose of this study is to compare medical students' evaluation of ultrasound anatomy teaching by clinicians and anatomists. Hands-on interactive ultrasound sessions were scheduled as part of the gross anatomy course following principles of adult learning and instructional design. Seven teachers (three anatomists and four clinicians) taught in each session. Before each session, anatomists were trained in ultrasound by clinicians. Students were divided into groups, rotated teachers between sessions, and completed evaluations. Results indicated students perceived the two groups as comparable for all factors except for knowledge organization and the helpfulness of ultrasound for understanding anatomy (P teach living anatomy using ultrasound with minimal training as well as clinicians, and encourage the teaching of living anatomy by anatomists in human anatomy courses using ultrasound. Repeating this study at a multicenter level is currently being considered to further validate our conclusion. © 2013 American Association of Anatomists.

  17. Frequency in Usage of FCAT-Approved Anatomical Terms by North American Anatomists (United States)

    Martin, Bradford D.; Thorpe, Donna; Barnes, Richard; DeLeon, Michael; Hill, Douglas


    It has been 10 years since the Federative Committee on Anatomical Terminology (FCAT) published Terminologia Anatomica (TA), the current authority on anatomical nomenclature. There exists a perceived lack of unity among anatomists to adopt many FCAT recommended anatomical terms in TA. An e-mail survey was sent to members of the American Association…

  18. Medical students and professional anatomists do not perceive gender bias within imagery featuring anatomy. (United States)

    Morgan, Susan; Plaisant, Odile; Lignier, Baptiste; Moxham, Bernard J


    Previous studies suggest that, while both medical students and professional anatomists recognize the importance of gender issues and do not wish to associate with sexism, most are unaware of the possible negative aspects of sexism within anatomy (Morgan et al. , J. Anat. 224:352-365; , Clin. Anat. 29:892-910). To further investigate this issue, we provided second year medical students at Cardiff University (n = 293) and at the University of Paris Descartes, Sorbonne Paris Cité (n = 142) and professional anatomists (n = 208) with a questionnaire inviting them to address the possibility that gender factors within anatomical imagery (both historical and contemporary) hinder the dispassionate representation of anatomy. Ethical approval for the survey was obtained from the universities at both Cardiff and Paris. In the light of previous findings, the hypothesis tested was that medical students and professional anatomists do not perceive a gender bias when reflected in imagery that is based on anatomical iconography. Our survey results support this hypothesis and suggest that most students and anatomists are unaware of the possible negative aspects of sexism within the culture of anatomy. We consequently recommend that teachers of anatomy and authors of anatomical textbooks should be aware of the possibility of adverse effects on professional matters relating to equality and diversity issues when using imagery.

  19. Sir William Turner (1832-1916) - Lancastrian, anatomist and champion of the Victorian era. (United States)

    Wessels, Quenton; Correia, Janine Carla; Taylor, Adam M


    Sir William Turner, a Lancastrian, was renowned as a scientist, anatomist and a great reformer of medical education. His students became anatomists at various international institutions, which consequently shaped the future of anatomy as a subject matter both in the United Kingdom and in South Africa. Although Turner's accomplishments have been documented, little is known about the details that determined his career path and the individuals that shaped his future. Here the authors aim to highlight some aspects of Turner's academic achievements and his personal life as well as how he crossed paths with other great minds of the Victorian era including Richard Owen, Charles Darwin, James Paget and Joseph Lister. © The Author(s) 2015.

  20. Anatomists' views on human body dissection and donation: an international survey. (United States)

    Arráez-Aybar, Luis-Alfonso; Bueno-López, José Luis; Moxham, Bernard John


    A survey was conducted to test three hypotheses: anatomists believe that dissection by students conveys not just anatomical knowledge but also essential skills and attitudes, including professionalism; anatomists approve of the donation of their own bodies or body parts/organs for medical/health-care training and research; attitudes towards body dissection and donation are not dependent upon gender or upon the extent of teaching experience, but are related to transcendental convictions relating to beliefs in the afterlife. Eighty-one anatomists, from 29 countries responded to the survey; 80% indicated that they required medical/health-care students to dissect human cadavers (60% females-86% males, p=0.02). Most teachers recorded that dissection was an instrument for training undergraduate students, an instrument for the development of professional skills, and an instrument to help to control emotions in the future doctor rather than being only a means of teaching/learning anatomy facts. Males were more receptive to the concept that dissection helps to control emotions in the future doctor (p=0.02). Most teachers (75%) said they were willing to donate their bodies, 41% saying they would donate body organs only, 9% would donate their entire bodies only, 25% would separately donate organs and also the entire body. The willingness to donate increased significantly with the years of teaching experience (p=0.04). Teachers who were not believers in the afterlife were more likely to donate their organs/bodies than were believers (p=0.03). Our findings showed that anatomists' attitudes towards body dissection and donation are dependent upon gender, upon the extent of teaching experience, and upon transcendental convictions.

  1. Spilling the beans on java 3D: a tool for the virtual anatomist. (United States)

    Guttmann, G D


    The computing world has just provided the anatomist with another tool: Java 3D, within the Java 2 platform. On December 9, 1998, Sun Microsystems released Java 2. Java 3D classes are now included in the jar (Java Archive) archives of the extensions directory of Java 2. Java 3D is also a part of the Java Media Suite of APIs (Application Programming Interfaces). But what is Java? How does Java 3D work? How do you view Java 3D objects? A brief introduction to the concepts of Java and object-oriented programming is provided. Also, there is a short description of the tools of Java 3D and of the Java 3D viewer. Thus, the virtual anatomist has another set of computer tools to use for modeling various aspects of anatomy, such as embryological development. Also, the virtual anatomist will be able to assist the surgeon with virtual surgery using the tools found in Java 3D. Java 3D will be able to fulfill gaps, such as the lack of platform independence, interactivity, and manipulability of 3D images, currently existing in many anatomical computer-aided learning programs.

  2. Beyond victimhood. The struggle of Munich anatomist Titus von Lanz during National Socialism. (United States)

    Schütz, Mathias; Waschke, Jens; Marckmann, Georg; Steger, Florian


    The article analyzes the life and career of the anatomist Titus von Lanz (1897-1967) of Munich focusing on the period of National Socialism (NS). Von Lanz lost his position as an associate professor at the Anatomical Institute of Munich University because of his marriage to a "half-Jewish" woman in 1938. In contrast to most of his colleagues affected by National Socialist measures, von Lanz had opportunities to save his career and made extensive use of them. His story is that of a complicated struggle for the continuation of his work, involving a wide range of supporters from prestigious physicians to high-ranking National Socialist officials as well as the alienation of his colleagues at the Munich department of anatomy. The article tries to clarify these developments through the presentation of his social background, his supporters, his enemies, the research he conducted during NS and von Lanz' own remembrance of these developments from the post-war period. It aims at laying out a critical appreciation of his motives and actions, thereby contributing to the understanding of individual behavior of anatomists under NS. Copyright © 2015 Elsevier GmbH.

  3. Sexism within anatomy as perceived by professional anatomists and in comparison with the perceptions of medical students. (United States)

    Morgan, Susan; Plaisant, Odile; Lignier, Baptiste; Moxham, Bernard J


    Two hundred and eight professional anatomists responded to a questionnaire inviting them to address the possibility that social/gender factors hinder the dispassionate representation of anatomy. Ethical approval for the study was obtained from Cardiff University. The results of the survey provided comparisons with the attitudes of medical students that have previously been reported (Morgan et al., 2014). Although a few differences were discerned between females and males in our surveys and between anatomists and medical students, overall our findings suggest that, while both professional anatomists and medical students recognize the importance of gender issues and do not wish to associate with sexism, most are unaware of the possible negative aspects of sexism within anatomy. We recommend that teachers of anatomy should become more aware of the possibility of adverse effects on professional matters relating to equality and diversity issues. Clin.

    Tubbs, R Shane; Mortazavi, Martin M; Shoja, Mohammadali M; Loukas, Marios; Cohen-Gadol, Aaron A


    Many physicians are familiar with the parotid duct and the Danish physician/anatomist's name associated with it. However, most are unaware of Niels Stensen's life and his significant contributions to the early study of the brain. This physician of the Medici court was clearly ahead of his time and found errors in the publications of such giants as Varolius and Willis. The present review discusses the life of this seventeenth century anatomist, physician, and priest/bishop and highlights his contributions to neuroanatomy.

  5. Knowledge-based client-server approach to structural information retrieval: the Digital Anatomist Browser. (United States)

    Brinkley, J F; Eno, K; Sundsten, J W


    Structural information can be defined as data and knowledge about biological objects ranging in size from molecules to the whole body. A framework is described for organizing structural information around a well-defined set of terminology and semantic relationships, and for disseminating multimedia structural information by means of a wide-area information server that is accessible over the internet. A Macintosh-based client of this server, called the Digital Anatomist Browser, has been used to teach neuroanatomy for the last 2 years. The client-server approach provides each student unlimited access to a rapidly growing knowledge base of structural biology that, while immediately useful for anatomy teaching, has the potential to be an organizing framework for other kinds of medical knowledge as well.

  6. Anatomist and the pioneer of radiology Étienne Destot--95th anniversary of his death. (United States)

    Báča, Václav; Kachlík, David; Báčová, Tereza; Bartoška, Radek; Marvan, Jiří; Douša, Pavel; Secrest, Thomas; Džupa, Valér


    Destot was a leading pioneer in radiology, a pupil of Ollier, an anatomist, and researcher who followed in the experimental medicine tradition of Claude Bérnard. This work is an extensive, in depth, look at the life and work of Étienne Destot. On February 5, 1896, he began performing X-ray examinations, less than two months after Roentgen's discovery! His pioneering work described a space bordered by the hamate, capitate, triquetrum, and lunate; this space is now known as Destot's space. Tanton stated that Destot was the first to reveal the mechanism of fractures of the posterior margin of the distal tibia and to emphasize their clinical relevance; in honor of this contribution, Tanton named such a fracture the “fracture of Destot.” Moreover, Destot is credited with being the first physician to use the term “pilon” in the orthopedic literature. He first described fractures of the scaphoid in 1905. He also described superficial hematomas, Destot's sign, located above the inguinal ligament or in the scrotum or thigh. Such hematomas are indicative of pelvic fractures. Destot is credited with inventing or improving many pieces of medical equipment (e.g., Lambotte's screw plates, anastomotic boutons for the digestive tube, monopolar endocavital radiological tubes). He was also active in developing technical aspects of equipment (e.g., radioscopic examination of the heart, a prototype of the mobile radiological laboratory). Étienne Destot is best known as a radiologist; however, his influence extends well beyond this field. He was an anatomist and surgeon, the founder of radiology in Lyon, prosector, physician, electrician, researcher, and artist.

  7. [The anatomists in Algiers during the French colonial period (1830-1962)]. (United States)

    Le Minor, Jean-Marie


    A remarkable anatomical school existed in Algiers during the French colonial period from 1830 to 1962. From 1832 to 1836, in the first military hospital of Algiers, Lucien Jean Baptiste Baudens (1804-1857) already started lectures of anatomy. A School of Medicine was created in Algiers in 1857 and opened in 1859 ; it was transformed in a Faculty of Medicine in 1909. Five professors occupied the chair of anatomy from 1859 to 1962 : Dr Patin from 1859 to 1869, Paulin Trolard (1842-1910) from 1869 to 1910, Jean Amédée Weber (1877-1966) from 1908 to 1917, Emile Leblanc from 1918 to 1939, and René-Marcel de Ribet (1894-1967) from 1940 to 1962. A second chair devoted to medico-surgical anatomy and surgical technique was created in 1957 and occupied by René Bourgeon (1912-1996) from 1957 to 1962. Some of the major works of those anatomists are evoked.

  8. An exploration of anatomists' views toward the use of body painting in anatomical and medical education: An international study. (United States)

    Cookson, Natalie E; Aka, Justine J; Finn, Gabrielle M


    Previous research has explored the experiences of medical students using body painting as a learning tool. However, to date, faculty experiences and views have not been explored. This international qualitative study utilized a grounded theory approach with data collection through interviews with academics and clinicians who utilized body painting as part of their anatomical teaching. Twenty-six anatomists participated in the study from 14 centers worldwide. Three themes emerged from the data: (1) the efficacy of body painting, (2) the promotion of knowledge retention and recall, (3) considerations and practicalities regarding the use of body painting as a teaching tool. Subthemes show that body painting is used as an adjunct to the curriculum for teaching surface anatomy and peer examination. Benefits included diffusing the formal curricula, high student engagement and learning for future clinical practice. Body painting was advocated for promoting knowledge retention and recall, particularly learning through the process of cognitive load due to combining the use of color and kinesthetic learning with anatomical theory. Critical discussions surfaced on the topic of undressing in the classroom due to cultural and personal considerations possibly leading to unequal involvement and different learning experiences. Overall results support previous research showing that anatomists appreciate body painting as an effective, enjoyable, engaging and cost efficient adjunct to the multimodal anatomy curriculum. The role of cognitive load theory in learning anatomy through body painting emerged from the data as a possible theoretical framework supporting learning benefits from body painting and is suggested for further investigation.

    Catala, M


    The development of the embryo and foetus fascinates, but its study in humans is difficult because of both technical and ethical problems. Auguste d'Eternod, Swiss embryologist, published in 1913 an article entitled "The early stages of the human egg" in the Comptes Rendus de l'Association des Anatomistes, the ancestor of the journal Morphologie. This work is focused not only on the early stages of development: fertilization, cleavage of the egg, blastocyst formation, gastrulation, but also on the extra-embryonic processes characteristic of mammals. On the occasion of the centenary of the publication of this work, I propose a critical review by placing the data published in the literature and historical context of the time. Finally, I try to extract from these observations the concepts that are still used today by embryologists. Copyright © 2014 Elsevier Masson SAS. All rights reserved.

  10. What a pity the master cannot admire his pupil's work: the autopsy of the anatomist Antonio Cocchi (1695-1758) performed by his pupil Saverio Manetti. (United States)

    Santi, Raffaella; Conti, Andrea A; Nesi, Gabriella


    Antonio Cocchi (1695-1758) was a physician, sanitary administrator, and Professor of Anatomy at the University of Florence. Wide-ranging in his interests, he was also a philologist, botanist, and a cultured traveler through 18th-century Europe. After Cocchi died, his pupil Saverio Manetti (1723-1785) reported, in a private letter on the state of health of his renowned master, the circumstances of his death and the autopsy findings. In an endeavour to determine the cause of death, Manetti accurately described the symptoms and clinical signs preceding the exitus of Antonio Cocchi and related them to the autopsy results. Interestingly, his lifestyle habits, past medical history, and family diseases were all considered when making the diagnosis. This handling of the matter clearly proceeds from Cocchi's teachings. As an anatomist, Cocchi believed autopsy to be a fundamental tool in achieving new insights into medicine while, as a professor, he emphasized the didactic relevance of autopsy in medical education. Manetti's letter appears as a surprisingly modern example of clinicopathological practice. Based on this informative document, we present an interpretation of the possible cause of the death of Antonio Cocchi, namely, congestive heart failure. Copyright © 2011 Elsevier Inc.

  11. An artificial neuro-anatomist

    International Nuclear Information System (INIS)

    Mangin, J.F.


    The fact that the human brain visual system is based on stereo-vision is a real handicap when analysing dense 3D representations of the human brain. The success of the methods of analysis based on the 3D proportional system has shown the advantage of using computer based system to interpret such complex images. The underlying strategy, however, is restricted to low level vision, which can not address any issue. Our approach advocates for the development of complete computer vision systems dedicated to the brain, which may be of great help for the future of neuroimaging. In our opinion, indeed, brain imaging is sufficiently focused to be a promising niche for the development of artificial intelligence. (N.C.)

  13. Was acupuncture developed by Han Dynasty Chinese anatomists? (United States)

    Shaw, Vivien; Mclennan, Amy K


    Anatomical dissection has begun to reveal striking similarities between gross anatomical structures and the system of nomenclature used in traditional Chinese acupuncture. This paper argues that acupuncture point nomenclature is rooted in systematic anatomical investigation of cadaveric specimens, and that acupuncture points and meridians are purposefully named to reflect observable physical form. Two types of evidence are compared: observations of physical structures based on anatomical dissection, and translation and analysis of original Chinese texts. Evidence is contextualized through in-depth practical understanding of acupuncture. Points designated as [Chinese character] tian (heavenly/superior), [Chinese character] xia (below/inferior), [Chinese character] liao (bone-hole), [Chinese character] fei (flying), [Chinese character] wei (bend), and [Chinese character] xi (mountain stream/ravine) are investigated. These acupuncture point names: (a) specify position; (b) reflect function and/or form; (c) indicate homologous structures; (d) mark unusual structures; and/or (e) describe the physical appearance of a deep (dissected) structure by likening it to a homologous everyday object. Results raise intriguing possibilities for developing an understanding of acupuncture points and meridians firmly based in the material and functional anatomy of the human body. Such an understanding has the potential to open new fields of thought about functional anatomy. It also has implications for future investigations into the mechanisms of acupuncture, and gives some insights into the possible origins of this iconic area of Chinese medicine. © 2016 Wiley Periodicals, Inc.

  15. [Dr. Jovan Andrejević Jols, the first Serbian anatomist life, work and achievement]. (United States)

    Sakač, Dejan; Sakač, Vladimir; Čabarkapa, Velibor; Bugarski, Vojislava


    Doctor Jovan Andrejević Joles was one of the most educated Serbs of the 19th century, a medical doctor, scientist, journalist and translator. He was born in 1883 in Novi Sad. Even as a student of medicine he was active in scientific work, which resulted in a paper entiteled "The fine structure of the liver," later published in one of the most eminent medical journals in Europe. He completed the study of medicine in Vienna. He did not accept the position at the Medical Faculty in Vienna, and returned to Novi Sad, where he quickly gained an excellent reputation as a physician. He participated in the founding of the Serbian National Theatre in 1861, he was also one of the most active contributors of Matica Srpska, wrote many articles, critics and reviews, and was also regarded as the founder of aesthetic romanticism in Serbs. With Laza Kostić, he was the first among the Serbs to translate Shakespeare. At that time, when he was only 30 years old, he wrote about a brand-new art - photography. He lived in a harmonious marriage with Jelena - Ilka Bajić, who after Joles' death remarried to a captain of the Serbian army, and after his murder, became famous for the assassination attempt of King Milan Obrenović (recorded in history textbooks as the "Rebellion of Ilka"). Dr. Jovan Andrejevć died prematurely of tuberculosis, at that time an incurable disease, in 1864 in Novi Sad.

    Full Text Available Otolaryngology is mainly associated with clinical practice. Despite of this actual evidence, otolaryngology can be considered, from historical point of view as a complex speciality made up of a mixture of several preclinical specialities as anatomy, histology, pathology and physiology. Several scientists who studied these specialities first, became then otolaryngologists and others were known in the medical literature because of their studies in other specialities than otolaryngology. Most of the historical papers were focused on the ear, other regions being neglected. This review presents the forgotten part of otolaryngology, especially its preclinical facts with importance in etiology and pathogenesis of various disease of the ear, nose and throat structures and thus, present work can be considered as a particular overview of „forgotten” otolaryngology

  18. Wandering anatomists and itinerant anthropologists: the antipodean sciences of race in Britain between the wars. (United States)

    Jones, Ross L; Anderson, Warwick


    While the British Empire conventionally is recognized as a source of research subjects and objects in anthropology, and a site where anthropological expertise might inform public administration, the settler-colonial affiliations and experiences of many leading physical anthropologists could also directly shape theories of human variation, both physical and cultural. Antipodean anthropologists like Grafton Elliot Smith were pre-adapted to diffusionist models that explained cultural achievement in terms of the migration, contact and mixing of peoples. Trained in comparative methods, these fractious cosmopolitans also favoured a dynamic human biology, often emphasizing the heterogeneity and environmental plasticity of body form and function, and viewing fixed, static racial typologies and hierarchies sceptically. By following leading representatives of empire anatomy and physical anthropology, such as Elliot Smith and Frederic Wood Jones, around the globe, it is possible to recover the colonial entanglements and biases of interwar British anthropology, moving beyond a simple inventory of imperial sources, and crediting human biology and social anthropology not just as colonial sciences but as the sciences of itinerant colonials.

  1. Medieval and Renaissance anatomists: the printing and unauthorized copying of illustrations, and the dissemination of ideas. (United States)

    Lanska, Douglas J; Lanska, John Robert


    The vanguard that began to question Galenic anatomical dogma originated in northern Italy in the latter half of the thirteenth century, and not coincidentally this was where human dissection was introduced, which in turn eventually fostered the origins of realistic anatomical illustration in the late fifteenth century. With the advent of the printing press and moveable type at this time, printed books began to supersede hand-copied medieval manuscripts, and labor-intensive techniques were soon developed to integrate text and illustrations on the printed page. The same technology was used to pirate the illustrations of prior authors with varying fidelity. Specific medieval and Renaissance anatomical illustrations can often be traced from their inceptions through different stages of development to the final printed images, and then through subsequent pirated versions in various abridgements or other compendia. The most important milestone in the development of anatomy and anatomical illustration was the publication in 1543 by Andreas Vesalii of De humani corporis fabrica (On the Fabric of the Human Body), commonly referred to simply as the Fabrica. With this work, Vesalii succeeded in coordinating a publication production team (author, artists, block cutters, publisher, and typesetters) to achieve an unprecedented integration of scientific discourse, medical illustration, and typography. However, despite Vesalii's valiant efforts to prevent unauthorized duplication, the illustrations from the Fabrica were extensively plagiarized. Although Vesalii found such piracy frustrating and annoying, the long-term effect was to make Vesalii's ideas known to a wider readership and to help solidify his own revolutionary contributions to anatomy. © 2013 Elsevier B.V.

  5. Juan Valverde de Amusco (1525-1588): an eminent anatomist of the renaissance or a plagiarist of Vesalius? His work and its impact in renaissance anatomy. (United States)

    Markatos, Konstantinos; Arkoudi, Konstantina; Androutsos, Georgios


    The purpose of this study is to review and summarize the life and work of Juan Valverde de Amusco (1525-1588), his impact on the anatomy of the sixteenth century and focus on his controversy with Andreas Vesalius. A thorough search of the literature was undertaken in PubMed and Google Scholar as well as in history books through the internet and in History and Medical University libraries. Valverde took almost directly from Andreas Vesalius 38 pictures. Occasionally, however, Valverde corrected Vesalius' images, as in his depictions of the muscles of the eyes, nose and larynx. Valverde copied the work of Vesalius in many instances. Nevertheless, he had his fair share of contribution in the history of Anatomy; he managed to popularize and spread the new anatomy of the Rennaissance through his work which was far more cheaper than that of Vesalius; furthermore, his anatomic discoveries like the first depiction of the intracranial course of the carotid arteries (several decades before Willis's description), the extrinsic ocular muscles and the middle ear bones contribute to the spirit of the Scientific Revolution.

  9. Anatomy in the Third Reich: an outline, part 3. The science and ethics of anatomy in National Socialist Germany and postwar consequences. (United States)

    Hildebrandt, S


    Anatomists in National Socialist (NS) Germany did research on materials from animals and humans, including tissues from the bodies of NS victims. The research was competent but rarely innovative. This may be due to the isolation of the German research community from international developments, as well as to the dismissal of a great number of successful anatomists for racial or political reasons. Other research was unproductive because of its foundation in the pseudoscience of racial hygiene. Anatomists in the Third Reich acted according to a new set of medical ethics favored by the NS regime. Not the individual human being but the "body of the people" as a whole was the object of this ethics. Every action was ethical that ensured the health of the German people, including sterilization, so-called euthanasia, and finally mass murder. Anatomists made use of the opportunities given to them by the NS regime, which led to the postmortem utilization of the bodies of NS victims. After the war, most anatomists retained their positions and NS history was not discussed until the later 20th century. Since then, historical research and public discussions have led to an increased awareness of questions of ethics in anatomy. The history of anatomy in the Third Reich illustrates that the theory and practice of a science is dependent on the political system it exists in, and that the scientists' competence not only in their science but also in politics and ethics is a prerequisite for the freedom of science.

  10. Wolfgang Bargmann (1906-1978) and Heinrich von Hayek (1900-1969): careers in anatomy continuing through German National Socialism to postwar leadership. (United States)

    Hildebrandt, Sabine


    None of the existing studies on the history of anatomy in National Socialism (NS) has yet explored the careers of those younger anatomists, whose professional development continued through NS times and who attained prominence in postwar German and Austrian anatomy. As they became modern anatomists' teachers and role models, the revelation that men like Wolfgang Bargmann and Heinrich von Hayek had used bodies of the executed for research in their early careers has recently led to some consternation. This study contributes to the analysis of the moral challenges inherent to a science that relies on work with "material" from human bodies and its interaction with its political environment. The results reveal that Bargmann and Hayek behaved like most other anatomists at the time, in that they used bodies of the executed for research and in that they joined the NS party or other NS political groups. As ambitious and successful young anatomists they may have felt that an early joining of NS affiliations was inevitable for the advancement of their careers. They and most of their colleagues became in some measure complicit with the NS regime. The complicated biographical realities of such luminous postwar figures as Bargmann and Hayek should lead modern anatomists to the questioning of their own ethical and political decisions in politically less demanding times.

  11. [Anatomy in National Socialism: stages of an ethical transgression]. (United States)

    Hildebrandt, Sabine


    Systematic research on the history of anatomy in National Socialism (NS) has only started in recent years. It has shown that anatomists used the bodies of NS victims for anatomical teaching and research purposes. In this they became complicit with the NS regime. There was a high percentage of Nazi party members among the anatomists, but at the same time there were anatomists whose careers were disrupted for so-called "racial" and political reasons. Decisive aspects of this history are first, the fact that traditional sources of anatomical body procurement included increasing numbers of NS victims and second, the gradual change of the traditional anatomical paradigm of working with the dead to a new paradigm of working with the "future dead" in human experimentation. This history has importance for the development of new ethical guidelines in anatomy.

  12. Genealogy of John and Charles Bell: their relationship with the children of Charles Shaw of Ayr. (United States)

    Kaufman, M


    The Reverend William Bell had six children who survived infancy. Two of his sons entered the legal profession and two other sons became distinguished anatomists and surgeons--John Bell, said for 20 years to have been the leading operating surgeon in Britain and throughout the world--and Sir Charles Bell, possibly the most distinguished anatomist and physiologist of his day. Information is not known about the fifth son or their sister. Charles Shaw, a lawyer of Ayr, had four sons and two daughters who survived infancy. Two of his sons, John and Alexander, became anatomists and later surgeons at the Middlesex Hospital, and both worked closely with Charles Bell at the Great Windmill Street School of Anatomy. His third son entered the law and his fourth son became a distinguished soldier. The two daughters of Charles Shaw married into the Bell family: Barbara married George Joseph Bell and Marion married Mr (later Sir) Charles Bell.

  13. The naming game: A discrepancy among the medical community. (United States)

    Loukas, Marios; Aly, Islam; Tubbs, R Shane; Anderson, Robert H


    As anatomists we rely on the nomenclature of structures in order to describe them appropriately, particularly their orientation in respect to their surrounding. The terminology used by the anatomist to describe an organ, muscle, or nerve within the body is taught to medical students as law. Students learn to describe structures in the "anatomical position", which has been accepted in the literature since the original Latin Nomina Anatomica. They therefore familiarize themselves with the use of terms such as superior, inferior, posterior and anterior to describe all anatomical structures, except in respect of the heart. The heart is still described in the original Valentine position. As anatomists we owe it to the medical and research community to correct the nomenclature to minimize confusion, and to describe the heart properly in respect to its surrounding structures. © 2015 Wiley Periodicals, Inc.

  14. The case of Robert Herrlinger: a unique postwar controversy on the ethics of the anatomical use of bodies of the executed during National Socialism. (United States)

    Hildebrandt, Sabine


    Historical evidence shows that German anatomists used bodies of executed victims of the National Socialist (NS) regime for anatomical purposes. However, there has been little direct information on these anatomists' thoughts and motivations, and a public discussion of their activities and ethics only started in the late 1980s. The present study documents a unique postwar controversy surrounding the promotion of the anatomist and medical historian Robert Herrlinger at the university of Würzburg in the late 1950s. This intramural debate had originally been mentioned by Goetz Aly in 1987. Herrlinger's files record his career as a representative of the discipline of medical history at the university of Würzburg from 1951 to 1960. He never worked there as an active anatomist. When the university senate applied for his appointment as full professor in 1957, the internist Ernst Wollheim, the pediatrician Joseph Ströder, and the psychiatrist Heinrich Scheller strongly opposed this move in a dissenting opinion based on Herrlinger's anatomical work on bodies of executed NS-victims. They claimed that he lacked the moral prerequisites required in a teacher of medical ethics. A highly controversial debate followed and was remarkable for addressing most of the questions of the ethical and political attitudes and responsibilities of anatomists in NS-Germany that are still being discussed today and are relevant for modern anatomy. It was also significant that Wollheim, Ströder and Scheller objected to Herrlinger in his role as a medical historian, not as an anatomist. The senate finally rejected the dissenting opinion and Herrlinger was promoted. Copyright © 2012 Elsevier GmbH. All rights reserved.

  15. The beauty of anatomy: visual displays and surgical education in early-nineteenth-century London. (United States)

    Berkowitz, Carin


    The early-nineteenth-century artist, anatomist, and teacher Sir Charles Bell saw anatomy and art as closely related subjects. He taught anatomy to artists and surgeons, illustrated his own anatomical texts, and wrote a treatise on the use of anatomy in art. The author explores the connections among visual displays representing human anatomy, aesthetics, and pedagogical practices for Bell and a particular group of British surgeon-anatomists. Creating anatomical models and drawings was thought to discipline the surgeon's hand, while the study of anatomy and comparative anatomy would discipline the artist's eye. And for Bell, beauty made drawings into better pedagogical tools.

    Most anatomists agree that cadaver dissection serves as a superior teaching tool in human anatomy education. However, attitudes toward body donation vary widely between different individuals. A questionnaire was developed to determine the attitudes toward body and organ donation among those who learn the most from cadavers: medical students,…

  17. Anatomy during the Third Reich--the Institute of Anatomy at the University of Marburg, as an example. (United States)

    Aumüller, G; Grundmann, K


    A complete documentation of German anatomical science and its representatives during the period of national socialism has not been published as yet--contrary to the situation in other medical disciplines. Instead of German anatomists, American anatomists have occasionally addressed this issue during their meetings and have reported on special aspects, such as the use of Nazi symbols in anatomical textbooks and atlases (Pernkopf 1952) and the use of corpses of justice victims for anatomical research and student education. Also, the genesis of the atrocious collection of "racial" skulls, initiated along with the SS-institution of the "Ahnenerbe" by the anatomist August Hirt of Strasbourg (who ordered more than 90 inmates from concentration camps to be murdered in the gas chamber built in the concentration camp of Natzweiler-Struthof close to Strasbourg, Alsace) has been described by Frederic Kasten and others. A broader view of the patterns of behaviour and political actions and fates of contemporary scientists, ranging from dismissal to clandestine opportunism, affirmative cooperation and fanatic activism can be obtained by the analysis of the activities in research, medical education and academic positions of the following members of the Institute of Anatomy at the Philipp-University in Marburg: Ernst Göppert, Eduard Jacobshagen, Ernst-Theodor Nauck, Adolf Dabelow, Helmut Becher and Alfred Benninghoff, whose activities and fates differ in several respects and allow more general deductions. Also, the individual fates of a number of prosecuted Jewish anatomists (Wassermann, München; Poll, Hamburg), of devoted and active members of the Nazi party (Clara, Leipzig; Blotevogel, Breslau) and of criminal fanatics (Hirt, Strasbourg; Kremer, Münster) are briefly discussed. The present contribution is an attempt to initiate a more detailed study of all German departments of anatomy during the Hitler regime and to generate a public discussion among the younger generation of

  18. The amount of information provided in articles published in clinical anatomy and surgical and radiologic anatomy regarding human cadaveric materials and trends in acknowledging donors/cadavers. (United States)

    Gürses, İlke Ali; Coşkun, Osman; Gürtekin, Başak; Kale, Ayşin


    Appreciating the contribution of donor-cadavers to medical education is a well observed practice among anatomists. However, the appreciation of their contribution in research and scientific articles remains dubious. We aimed to evaluate how much data anatomists provide about specimens they have used and how frequently anatomists acknowledge their cadavers in published articles. We evaluated all articles performed on human cadaveric specimens that were published in Clinical Anatomy and Surgical and Radiologic Anatomy between January 2011 and December 2015. We evaluated how much data on the demographics, preservation method(s), source, and ethical/legal permissions regarding cadavers were provided. We also evaluated the number of articles that acknowledged donor-cadavers. The majority of articles provided demographic data (age and sex) and preservation method used in the article. The source of the specimens was not mentioned in 45.6 % of the articles. Only 26.2 % of the articles provided a degree of consent and only 32.4 % of the articles reported some form of ethical approval for the study. The cadavers and their families were acknowledged in 17.7 % of the articles. We observed that no standard method for reporting data has been established. Anatomists should collaborate to create awareness among the scientific community for providing adequate information regarding donor-cadavers, including source and consent. Acknowledging donor-cadavers and/or their families should also be promoted. Scientific articles should be used to create a transparent relationship of trust between anatomists and their society.

  19. Curriculum integration = course disintegration: what does this mean for anatomy? (United States)

    Bolender, David L; Ettarh, Rajunor; Jerrett, David P; Laherty, Richard F


    Many basic scientists including anatomists are currently involved in decisions related to revisions of the undergraduate medical curriculum. Integration is a common theme in many of these decisions. As described by Harden, integration can occur along a multistep continuum from independent, discipline-based courses to a completely interdisciplinary curriculum. For anatomy, each derivative of curricular integration can be shown to involve progressive disruptions of the temporal and topographical relationship between organ systems in a body region, of the temporal relationship with other courses in a harmonized curriculum, and of the relationships between components of organ systems when integration is implemented in thematic curricula. Drawing from our experience teaching in various types of integrated medical curricula, we encourage readers to proceed cautiously with their curricular decisions because each one can have gains and losses that may impact learning in the new format.

  20. Advertising cadavers in the republic of letters: anatomical publications in the early modern Netherlands. (United States)

    Margócsy, Dániel


    This paper sketches how late seventeenth-century Dutch anatomists used printed publications to advertise their anatomical preparations, inventions and instructional technologies to an international clientele. It focuses on anatomists Frederik Ruysch (1638-1732) and Lodewijk de Bils (1624-69), inventors of two separate anatomical preparation methods for preserving cadavers and body parts in a lifelike state for decades or centuries. Ruysch's and de Bils's publications functioned as an 'advertisement' for their preparations. These printed volumes informed potential customers that anatomical preparations were aesthetically pleasing and scientifically important but did not divulge the trade secrets of the method of production. Thanks to this strategy of non-disclosure and advertisement, de Bils and Ruysch could create a well-working monopoly market of anatomical preparations. The 'advertising' rhetorics of anatomical publications highlight the potential dangers of equating the growth of print culture with the development of an open system of knowledge exchange.

  1. Controlling the vocabulary for anatomy. (United States)

    Baud, R H; Lovis, C; Rassinoux, A M; Ruch, P; Geissbuhler, A


    When confronted with the representation of human anatomy, natural language processing (NLP) system designers are facing an unsolved and frequent problem: the lack of a suitable global reference. The available sources in electronic format are numerous, but none fits adequately all the constraints and needs of language analysis. These sources are usually incomplete, difficult to use or tailored to specific needs. The anatomist's or ontologist's view does not necessarily match that of the linguist. The purpose of this paper is to review most recognized sources of knowledge in anatomy usable for linguistic analysis. Their potential and limits are emphasized according to this point of view. Focus is given on the role of the consensus work of the International Federation of Associations of Anatomists (IFAA) giving the Terminologia Anatomica.

  2. The “Ice Age” of Anatomy and Obstetrics: (United States)

    Al-Gailani, Salim


    summary In the late nineteenth century anatomists claimed a new technique—slicing frozen corpses into sections—translated the three-dimensional complexity of the human body into flat, visually striking, and unprecedentedly accurate images. Traditionally hostile to visual aids, elite anatomists controversially claimed frozen sections had replaced dissection as the “true anatomy.” Some obstetricians adopted frozen sectioning to challenge anatomists’ authority and reform how clinicians made and used pictures. To explain the successes and failures of the technique, this article reconstructs the debates through which practitioners learned to make and interpret, to promote or denigrate frozen sections in teaching and research. Focusing on Britain, the author shows that attempts to introduce frozen sectioning into anatomy and obstetrics shaped and were shaped by negotiations over the epistemological standing of hand and eye in medicine.

  3. Internal architecture of the proximal femur--Adam's or Adams' arch? Historical mystery. (United States)

    Bartonícek, J


    The designation 'Adam Bogen' describing the thick medial cortex of the femoral neck is an incorrect term. This arch was described by Robert Adams (1795-1871), an outstanding Irish anatomist and surgeon. He was famous mainly for his book on gout and the description of disorders of cardiac rhythm, the so-called Adams-Stokes syndrome. He published his original description in the today unfortunately almost forgotten Cyclopaedia of Anatomy and Physiology, Vol. II (London, Longman, 1836-1839). The main editor of this monumental six-volume work was the famous anatomist and surgeon R.B.Todd. This book represents a significant source of information on diseases and injuries of the great joints (shoulder, elbow, wrist, knee, ankle).

    Bowen, Garvin; Gonzales, Jocelyn; Iwanaga, Joe; Fisahn, Christian; Loukas, Marios; Oskouian, Rod J; Tubbs, R Shane


    Few individuals in history have exerted so great an influence and made such extensive contributions to so many disciplines as Leonardo da Vinci. Da Vinci's inquisitive, experimental mentality led him to many discoveries, such as spinal cord function and the proper anatomy of several organ systems. Respected not only as an artist but also as an anatomist, he made many significant contributions to the field. This article explores da Vinci's drawings, in relation to the anatomy of the human spine.

  5. Insights into the Freiburg Anatomical Institute during National Socialism, 1933-1945. (United States)

    Hildebrandt, Sabine


    The Anatomical Institute at the Albert-Ludwigs-Universität Freiburg is among the anatomical departments for which a comprehensive account of its history during National Socialism (NS) is still missing. Previous investigations (such as in: Grün et al., 2002) have revealed the political activities of some anatomists, but, in the absence of relevant body-registers, a more comprehensive examination of the anatomical body procurement has not been attempted. The inspection of records in university and municipal archives allows insight into the activities in the institute within the historical context. The Freiburg Institute shared the experience of the impact of NS politics with other German anatomies. Four anatomists were dismissed because of NS racial discrimination, and chairman von Möllendorf left for political reasons. His successor Nauck's appointment was politically motivated, as he was a staunch Nazi. His colleagues were also members of NS political organizations. Body procurement was controversial between the public and the anatomists in Freiburg prior to and following the Third Reich, and much of the anatomists' efforts focused on the improvement of the body supply. In 1935, and, again during the war, the number of bodies was sufficient for anatomical education. Among the traditional sources of body procurement were increasing numbers of NS victims. Forty-four of them can be identified, among them 21 forced laborers and their children who died of so-called natural causes, and 22 men who had been executed at Stuttgart prison on April 6, 1943. While the victims' names have been ascertained, their biographies still need restoration to ensure an appropriate commemoration. Copyright © 2016 Elsevier GmbH. All rights reserved.

    Dr?scher, Ariane


    From the late nineteenth century onwards, the phenomena of vision and the anatomy and physiology of the eye of marine animals induced many zoologists, ethologists, physiologists, anatomists, biochemists, and ophthalmologists to travel to the Zoological Station in Naples. Initially, their preferred research objects were fish, but it soon became evident that cephalopods have features which make them particularly suited to research. After the first studies, which outlined the anatomical structur...

    Mejías Stuven, Roberto


    Terminology is a common technical language, particularly in the fields of morphology. Over many years, Terminologia Anatomica has been the subject of much controversy and disagreement. At the present time, anatomists adopted Latin as the international language for Terminologia Anatomica. Under this worldwide adoption has been possible eliminate national differences, which were causing extreme confusion in instances where the same structure was known by several names. The present paper offers ...

    Wynfrid Laurence Henry Duckworth was one of the leading comparative anatomists of the first half of the 20th century, and he made important contributions to biological anthropology and anatomical education. In his eighth decade Duckworth turned his considerable gifts to the history of medicine. This paper examines the circumstances of his English translation of the second half of Anatomical Procedures, one of Galen's most important works.

  12. Bodies for Anatomy Education in Medical Schools: An Overview of the Sources of Cadavers Worldwide. (United States)

    Habicht, Juri L; Kiessling, Claudia; Winkelmann, Andreas


    The International Federation of Associations of Anatomists (IFAA) recommended in 2012 that only donated bodies be used for anatomy teaching and research. However, in many countries around the world, anatomists still depend on bodies that do not stem from voluntary donations by the deceased, but rather are "unclaimed." A broad search of the literature was conducted to produce a baseline overview of the sources of cadavers used for anatomy teaching in undergraduate medical curricula on a global scale. Information from the literature search was supplemented with data from a 2016-2017 survey of selected senior local anatomists. Of 165 countries with medical schools, information was gathered for 71. In 22 (32%) of the 68 countries that use cadavers for anatomy teaching, body donation is the exclusive source of bodies. However, in most other countries, unclaimed bodies remain the main (n = 18, 26%) or exclusive (n = 21, 31%) source. Some countries import cadavers from abroad, mainly from the United States or India. In one country, bodies of executed persons are given to anatomy departments. The heterogeneous geographical distribution of body sources cannot easily be accounted for, but religion, culture, and folk beliefs about what should happen to bodies after death seem to play a role. Implementation of the IFAA recommendations still has a long way to go, but it is encouraging that functioning body donation programs exist on all continents and that there are examples of recent rises in donations and of anatomists initiating new donation programs.This is an open-access article distributed under the terms of the Creative Commons Attribution-Non Commercial-No Derivatives License 4.0 (CCBY-NC-ND), where it is permissible to download and share the work provided it is properly cited.

  15. Leonardo da Vinci and Andreas Vesalius; the shoulder girdle and the spine, a comparison. (United States)

    Ganseman, Y; Broos, P


    Leonardo Da Vinci and Andreas Vesalius were two important renaissance persons; Vesalius was a surgeon-anatomist who delivered innovative work on the study of the human body, Leonardo da Vinci was an artist who delivered strikingly accurate and beautiful drawings on the human body. Below we compare both masters with regard to their knowledge of the working of the muscles, their method and system of dissection and their system and presentation of the drawings. The investigation consisted of a comparison between both anatomists, in particular concerning their study on the shoulder girdle and spine, by reviewing their original work as well as already existing literature on this subject. The investigation led to the conclusion that the drawings mentioned meant a change in history, and were of high quality, centuries ahead of their time. Both were anatomists, both were revolutionary, only one changed history at the moment itself, while the other changed history centuries later. Leonardo has made beautiful drawings that are at a match with the drawings of today or are even better. Vesalius set the start for medicine as a science as it is until this day. Their lives differed as strongly as their impact. In the light of their time, the achievement they made was extraordinary.

  16. The women on Stieve's list: Victims of national socialism whose bodies were used for anatomical research. (United States)

    Hildebrandt, Sabine


    Research on the history of anatomy in the Third Reich has often concentrated on the influence of the National Socialist (NS) regime on anatomists and their consequent unethical activities. Only recently, the focus has shifted to NS victims whose bodies were used for anatomical purposes. As a first approach to learning more about the victims, this study investigated the persons whose names Hermann Stieve, chairman of the Anatomical Department at the University of Berlin, had listed after using their bodies for his research. The study draws a group portrait and recounts selected biographies of the 174 women and eight men on the list. Most women were of reproductive age, two-thirds were German and a majority was executed for political reasons. Among the executed were at least two pregnant women. The corrected names, biographical data, and nationalities of all persons on the list are published here. None of them volunteered to be dissected, nor were the anatomists at the time interested in the victims' personal background. Future work will have to focus on the investigation of further biographies so that numbers can be turned back into people. This history is a reminder to modern anatomy that ethical body procurement and the anatomists' caring about the body donor is of the utmost importance in a discipline that introduces students to professional ethics in the medical teaching curriculum.

  17. The virtual microscopy database-sharing digital microscope images for research and education. (United States)

    Lee, Lisa M J; Goldman, Haviva M; Hortsch, Michael


    Over the last 20 years, virtual microscopy has become the predominant modus of teaching the structural organization of cells, tissues, and organs, replacing the use of optical microscopes and glass slides in a traditional histology or pathology laboratory setting. Although virtual microscopy image files can easily be duplicated, creating them requires not only quality histological glass slides but also an expensive whole slide microscopic scanner and massive data storage devices. These resources are not available to all educators and researchers, especially at new institutions in developing countries. This leaves many schools without access to virtual microscopy resources. The Virtual Microscopy Database (VMD) is a new resource established to address this problem. It is a virtual image file-sharing website that allows researchers and educators easy access to a large repository of virtual histology and pathology image files. With the support from the American Association of Anatomists (Bethesda, MD) and MBF Bioscience Inc. (Williston, VT), registration and use of the VMD are currently free of charge. However, the VMD site is restricted to faculty and staff of research and educational institutions. Virtual Microscopy Database users can upload their own collection of virtual slide files, as well as view and download image files for their own non-profit educational and research purposes that have been deposited by other VMD clients.

  18. Information on the changes in the revised anatomical nomenclature of the lower limb veins. (United States)

    Kachlik, David; Pechacek, Vaclav; Musil, Vladimir; Baca, Vaclav


    Two consensus documents have appeared which revised the anatomical nomenclature of the venous system of the lower extremity. They changed and substantially extended the last valid version of the Latin anatomical nomenclature, Terminologia Anatomica, published by the Federative Committee on Anatomical Terminology, with approval of the International Federation of Associations of Anatomists, in 1998. The clinicians felt the need to adjust the terminology in order to better serve their purposes and to serve as a relevant theoretical base for correct diagnostic and appropriate treatment. First a consensus was made to expand and complete the nomenclature of the lower limb venous system during the 14th World Congress of the International Union of Phlebology in 2001. Another consensus was made again three years later, during 21st World Congress of the International Union of Angiology, under the auspices of Federative Committee on Anatomical Terminology and International Federation of Associations of Anatomists. The articles were compiled with the emphasis on the Latin terminology. Review of the original articles concerning the arrangement, variability and different nomenclature was performed thoroughly. The both documents comprise 89 terms of the veins of the lower extremity in both Latin and English. The clinicians, anatomists, and university teachers should follow the new extended anatomical nomenclature of the lower limb veins. The precise anatomical terminology can serve for diagnostic, treatment, and scientific purposes not only in the anatomy and angiology.

  19. Ultrasound imaging in medical student education: Impact on learning anatomy and physical diagnosis. (United States)

    So, Sokpoleak; Patel, Rita M; Orebaugh, Steven L


    Ultrasound use has expanded dramatically among the medical specialties for diagnostic and interventional purposes, due to its affordability, portability, and practicality. This imaging modality, which permits real-time visualization of anatomic structures and relationships in vivo, holds potential for pre-clinical instruction of students in anatomy and physical diagnosis, as well as providing a bridge to the eventual use of bedside ultrasound by clinicians to assess patients and guide invasive procedures. In many studies, but not all, improved understanding of anatomy has been demonstrated, and in others, improved accuracy in selected aspects of physical diagnosis is evident. Most students have expressed a highly favorable impression of this technology for anatomy education when surveyed. Logistic issues or obstacles to the integration of ultrasound imaging into anatomy teaching appear to be readily overcome. The enthusiasm of students and anatomists for teaching with ultrasound has led to widespread implementation of ultrasound-based teaching initiatives in medical schools the world over, including some with integration throughout the entire curriculum; a trend that likely will continue to grow.

  20. Style and non-style in anatomical illustration: From Renaissance Humanism to Henry Gray. (United States)

    Kemp, Martin


    Style is a familiar category for the analysis of art. It is less so in the history of anatomical illustration. The great Renaissance and Baroque picture books of anatomy illustrated with stylish woodcuts and engravings, such as those by Charles Estienne, Andreas Vesalius and Govard Bidloo, showed figures in dramatic action in keeping with philosophical and theological ideas about human nature. Parallels can be found in paintings of the period, such as those by Titian, Michelangelo and Hans Baldung Grien. The anatomists also claimed to portray the body in an objective manner, and showed themselves as heroes of the discovery of human knowledge. Rembrandt's painting of Dr Nicholas Tulp is the best-known image of the anatomist as hero. The British empirical tradition in the 18th century saw William Cheselden and William Hunter working with techniques of representation that were intended to guarantee detailed realism. The ambition to portray forms life-size led to massive volumes, such as those by Antonio Mascagni. John Bell, the Scottish anatomist, criticized the size and pretensions of the earlier books and argued for a plain style adapted to the needs of teaching and surgery. Henry Gray's famous Anatomy of 1858, illustrated by Henry Vandyke Carter, aspired to a simple descriptive mode of functional representation that avoided stylishness, resulting in a style of its own. Successive editions of Gray progressively saw the replacement of Gray's method and of all his illustrations. The 150th anniversary edition, edited by Susan Standring, radically re-thinks the role of Gray's book within the teaching of medicine.

  1. Evolution of illustrations in anatomy: a study from the classical period in Europe to modern times. (United States)

    Ghosh, Sanjib Kumar


    Illustrations constitute an essential element of learning anatomy in modern times. However it required a significant evolutionary process spread over centuries, for illustrations to achieve the present status in the subject of anatomy. This review article attempts to outline the evolutionary process by highlighting on the works of esteemed anatomists in a chronological manner. Available literature suggests that illustrations were not used in anatomy during the classical period when the subject was dominated by the descriptive text of Galen. Guido da Vigevano was first to use illustrations in anatomy during the Late Middle Ages and this concept developed further during the Renaissance period when Andreas Vesalius pioneered in illustrations becoming an indispensable tool in conveying anatomical details. Toward later stages of the Renaissance period, Fabricius ab Aquapendente endeavored to restrict dramatization of anatomical illustrations which was a prevalent trend in early Renaissance. During the 18th century, anatomical artwork was characterized by the individual styles of prominent anatomists leading to suppression of anatomical details. In the 19th century, Henry Gray used illustrations in his anatomical masterpiece that focused on depicting anatomical structures and were free from any artistic style. From early part of the 20th century medical images and photographs started to complement traditional handmade anatomical illustrations. Computer technology and advanced software systems played a key role in the evolution of anatomical illustrations during the late 20th century resulting in new generation 3D image datasets that are being used in the 21st century in innovative formats for teaching and learning anatomy. © 2014 American Association of Anatomists.

  2. A novel phased-concept course for the delivery of anatomy and orthopedics training in medical education. (United States)

    Klima, Stefan; Hepp, Pierre; Löffler, Sabine; Cornwall, Jon; Hammer, Niels


    Integration of anatomy and clinical teaching is a theoretical ideal, yet there is a worldwide paucity of such amalgamation. These teaching models provide support for medical trainees, an important element in Germany where orthopedic intern numbers have declined and anecdotal evidence suggests disinterest in orthopedics. The aim of the study was to develop an integrated anatomy-surgical course for undergraduate medical training, assess the model developed, and explore how medical students perceive orthopedics as a career. The course was to deliver medical anatomy and clinical orthopedic training, focusing on interdisciplinary teaching and learning, vertical integration of clinical knowledge and skills, and professional interaction. Survey evaluation of the course and students' perceptions of orthopedic careers was performed, including Likert-type responses rating variables of interest. A phased-concept program of five courses, each optional and under one-week in duration, was developed parallel to the undergraduate medical program. Delivered by anatomists and surgeons, courses included biomechanics, advanced dissection, surgical approaches, casts and implants, and sports medicine. Course data indicate positive support for course format, stimulation of interest, and high clinical relevance. Students are generally interested in surgery, and identify hierarchy, lawsuits, bureaucracy and physical stress as barriers to orthopedic careers. This novel phased-concept successfully delivers combined anatomy and surgery training in a vertically-integrated format while addressing students' clinical and professional skills. The format facilitates an appreciation of potential career options in orthopedics, while fostering professional skills during medical training. Barriers to careers in orthopedics can now be addressed in future courses. Anat Sci Educ 10: 372-382. © 2016 American Association of Anatomists. © 2016 American Association of Anatomists.

  3. Interactive anatomical and surgical live stream lectures improve students' academic performance in applied clinical anatomy. (United States)

    Shiozawa, Thomas; Butz, Benjamin; Herlan, Stephan; Kramer, Andreas; Hirt, Bernhard


    Tuebingen's Sectio Chirurgica (TSC) is an innovative, interactive, multimedia, and transdisciplinary teaching method designed to complement dissection courses. The Tuebingen's Sectio Chirurgica (TSC) allows clinical anatomy to be taught via interactive live stream surgeries moderated by an anatomist. This method aims to provide an application-oriented approach to teaching anatomy that offers students a deeper learning experience. A cohort study was devised to determine whether students who participated in the TSC were better able to solve clinical application questions than students who did not participate. A total of 365 students participated in the dissection course during the winter term of the 2012/2013 academic year. The final examination contained 40 standard multiple-choice (S-MC) and 20 clinically-applied multiple-choice (CA-MC) items. The CA-MC items referred to clinical cases but could be answered solely using anatomical knowledge. Students who regularly participated in the TSC answered the CA-MC questions significantly better than the control group (75% and 65%, respectively; P  0.05). The CA-MC questions had a slightly higher level of difficulty than the S-MC questions (0.725 and 0.801, respectively; P = 0.083). The discriminatory power of the items was comparable (S-MC median Pearson correlations: 0.321; CA-MC: 0.283). The TSC successfully teaches the clinical application of anatomical knowledge. Students who attended the TSC in addition to the dissection course were able to answer CA-MC questions significantly better than students who did not attend the TSC. Thus, attending the TSC in addition to the dissection course supported students' clinical learning goals.

  4. Vesalius on the anatomy and function of the recurrent laryngeal nerves: medical illustration and reintroduction of a physiological demonstration from Galen. (United States)

    Lanska, Douglas J


    The purpose of this article is to review the anatomical illustrations and physiological demonstrations of sixteenth-century Flemish-born anatomist and physician Andreas Vesalius concerning the recurrent laryngeal nerves. Although Vesalius was primarily an anatomist, he also used vivisection as a pedagogical device to help his students understand the function of structures within the fabric of the body that they had previously studied in anatomical detail. Vesalius's masterwork, De humani corporis fabrica or simply the Fabrica (1543, 1555), was ostensibly an anatomy text, but Vesalius included textual and figural references to his use of vivisection to explicate the function of specific structures. Even as he began to criticize the errors in Galen's anatomical works, Vesalius nevertheless adopted some of Galen's classic physiological demonstrations, in particular the ligation (and subsequent release) of the recurrent laryngeal nerves of a pig to demonstrate their role in generating the pig's squeal. Vesalius's illustrations concerning the recurrent laryngeal nerve in the Fabrica were of two types: elegant anatomical woodcut plates-unsurpassed for their clarity, accuracy, and detail - and the distinctly inelegant historiated initial Q, depicting a throng of putti busily engaged in vivisecting a pig. Vesalius' anatomical plates were heavily plagiarized while the historiated initials, showing the rough work of an anatomist or surgeon, were largely ignored and remain little recognized today. While Vesalius' anatomical illustrations of the recurrent laryngeal nerves contained some errors, they were a dramatic departure from prior meager efforts at medical illustration and indeed far surpassed all contemporary published illustrations by others. Vesalius was also influential in reviving Galen's approach to vivisection, at least for pedagogical purposes, if not really then yet as a full-fledged investigative technique.

  5. Style and non-style in anatomical illustration: From Renaissance Humanism to Henry Gray (United States)

    Kemp, Martin


    Style is a familiar category for the analysis of art. It is less so in the history of anatomical illustration. The great Renaissance and Baroque picture books of anatomy illustrated with stylish woodcuts and engravings, such as those by Charles Estienne, Andreas Vesalius and Govard Bidloo, showed figures in dramatic action in keeping with philosophical and theological ideas about human nature. Parallels can be found in paintings of the period, such as those by Titian, Michelangelo and Hans Baldung Grien. The anatomists also claimed to portray the body in an objective manner, and showed themselves as heroes of the discovery of human knowledge. Rembrandt’s painting of Dr Nicholas Tulp is the best-known image of the anatomist as hero. The British empirical tradition in the 18th century saw William Cheselden and William Hunter working with techniques of representation that were intended to guarantee detailed realism. The ambition to portray forms life-size led to massive volumes, such as those by Antonio Mascagni. John Bell, the Scottish anatomist, criticized the size and pretensions of the earlier books and argued for a plain style adapted to the needs of teaching and surgery. Henry Gray’s famous Anatomy of 1858, illustrated by Henry Vandyke Carter, aspired to a simple descriptive mode of functional representation that avoided stylishness, resulting in a style of its own. Successive editions of Gray progressively saw the replacement of Gray’s method and of all his illustrations. The 150th anniversary edition, edited by Susan Standring, radically re-thinks the role of Gray’s book within the teaching of medicine. PMID:20447244

  6. Dual-extrusion 3D printing of anatomical models for education. (United States)

    Smith, Michelle L; Jones, James F X


    Two material 3D printing is becoming increasingly popular, inexpensive and accessible. In this paper, freely available printable files and dual extrusion fused deposition modelling were combined to create a number of functional anatomical models. To represent muscle and bone FilaFlex 3D flexible filament and polylactic acid (PLA) filament were extruded respectively via a single 0.4 mm nozzle using a Big Builder printer. For each filament, cubes (5 mm 3 ) were printed and analyzed for X, Y, and Z accuracy. The PLA printed cubes resulted in errors averaging just 1.2% across all directions but for FilaFlex 3D printed cubes the errors were statistically significantly greater (average of 3.2%). As an exemplar, a focus was placed on the muscles, bones and cartilage of upper airway and neck. The resulting single prints combined flexible and hard structures. A single print model of the vocal cords was constructed which permitted movement of the arytenoids on the cricoid cartilage and served to illustrate the action of intrinsic laryngeal muscles. As University libraries become increasingly engaged in offering inexpensive 3D printing services it may soon become common place for both student and educator to access websites, download free models or 3D body parts and only pay the costs of print consumables. Novel models can be manufactured as dissectible, functional multi-layered units and offer rich possibilities for sectional and/or reduced anatomy. This approach can liberate the anatomist from constraints of inflexible hard models or plastinated specimens and engage in the design of class specific models of the future.

  7. Googling in anatomy education: Can google trends inform educators of national online search patterns of anatomical syllabi? (United States)

    Phelan, Nigel; Davy, Shane; O'Keeffe, Gerard W; Barry, Denis S


    The role of e-learning platforms in anatomy education continues to expand as self-directed learning is promoted in higher education. Although a wide range of e-learning resources are available, determining student use of non-academic internet resources requires novel approaches. One such approach that may be useful is the Google Trends © web application. To determine the feasibility of Google Trends to gain insights into anatomy-related online searches, Google Trends data from the United States from January 2010 to December 2015 were analyzed. Data collected were based on the recurrence of keywords related to head and neck anatomy generated from the American Association of Clinical Anatomists and the Anatomical Society suggested anatomy syllabi. Relative search volume (RSV) data were analyzed for seasonal periodicity and their overall temporal trends. Following exclusions due to insufficient search volume data, 29 out of 36 search terms were analyzed. Significant seasonal patterns occurred in 23 search terms. Thirty-nine seasonal peaks were identified, mainly in October and April, coinciding with teaching periods in anatomy curricula. A positive correlation of RSV with time over the 6-year study period occurred in 25 out of 29 search terms. These data demonstrate how Google Trends may offer insights into the nature and timing of online search patterns of anatomical syllabi and may potentially inform the development and timing of targeted online supports to ensure that students of anatomy have the opportunity to engage with online content that is both accurate and fit for purpose.

  8. Longitudinal retention of anatomical knowledge in second-year medical students. (United States)

    Doomernik, Denise E; van Goor, Harry; Kooloos, Jan G M; Ten Broek, Richard P


    The Radboud University Medical Center has a problem-based, learner-oriented, horizontally, and vertically integrated medical curriculum. Anatomists and clinicians have noticed students' decreasing anatomical knowledge and the disability to apply knowledge in diagnostic reasoning and problem solving. In a longitudinal cohort, the retention of anatomical knowledge gained during the first year of medical school among second-year medical students was assessed. In May 2011, 346 medical students applied for the second-year gastro-intestinal (GI) tract course. The students were asked to participate in a reexamination of a selection of anatomical questions of an examination from October 2009. The examination consisted of a clinical anatomy case scenario and two computed tomography (CT) images of thorax and abdomen in an extended matching format. A total of 165 students were included for analysis. In 2011, students scored significantly lower for the anatomy examination compared to 2009 with a decline in overall examination score of 14.7% (±11.7%). Decrease in knowledge was higher in the radiological questions, compared to the clinical anatomy cases 17.5% (±13.6%) vs. 7.9% (±10.0%), respectively, d = 5.17. In both years, male students scored slightly better compared to female students, and decline of knowledge seems somewhat lower in male students (13.1% (±11.1%) vs. 15.5% (±12.0%), respectively), d = -0.21. Anatomical knowledge in the problem-oriented horizontal and vertical integrated medical curriculum, declined by approximately 15% 1.5 year after the initial anatomy course. The loss of knowledge in the present study is relative small compared to previous studies.

  9. From chalkboard, slides, and paper to e-learning: How computing technologies have transformed anatomical sciences education. (United States)

    Trelease, Robert B


    Until the late-twentieth century, primary anatomical sciences education was relatively unenhanced by advanced technology and dependent on the mainstays of printed textbooks, chalkboard- and photographic projection-based classroom lectures, and cadaver dissection laboratories. But over the past three decades, diffusion of innovations in computer technology transformed the practices of anatomical education and research, along with other aspects of work and daily life. Increasing adoption of first-generation personal computers (PCs) in the 1980s paved the way for the first practical educational applications, and visionary anatomists foresaw the usefulness of computers for teaching. While early computers lacked high-resolution graphics capabilities and interactive user interfaces, applications with video discs demonstrated the practicality of programming digital multimedia linking descriptive text with anatomical imaging. Desktop publishing established that computers could be used for producing enhanced lecture notes, and commercial presentation software made it possible to give lectures using anatomical and medical imaging, as well as animations. Concurrently, computer processing supported the deployment of medical imaging modalities, including computed tomography, magnetic resonance imaging, and ultrasound, that were subsequently integrated into anatomy instruction. Following its public birth in the mid-1990s, the World Wide Web became the ubiquitous multimedia networking technology underlying the conduct of contemporary education and research. Digital video, structural simulations, and mobile devices have been more recently applied to education. Progressive implementation of computer-based learning methods interacted with waves of ongoing curricular change, and such technologies have been deemed crucial for continuing medical education reforms, providing new challenges and opportunities for anatomical sciences educators.

    A.R. Shams


    Conclusion: It is concluded that PT variations may affect the function of upper limb. Knowledge of such variations is important to anatomists, radiologists, anesthesiologists and surgeons in evaluation of unexplained sensory and motor loss after trauma and surgical interventions to the upper limb. The presence of anatomical variations is often used to explain unexpected clinical signs and symptoms and for differential diagnosis of uncommon clinical conditions. In this study Clinical consideration of the present variations has been discussed. The present variation should be considered in the etiology of PT syndrome.

  12. Julius Caesar Arantius (Giulio Cesare Aranzi, 1530-1589) and the hippocampus of the human brain: history behind the discovery. (United States)

    Bir, Shyamal C; Ambekar, Sudheer; Kukreja, Sunil; Nanda, Anil


    Julius Caesar Arantius is one of the pioneer anatomists and surgeons of the 16th century who discovered the different anatomical structures of the human body. One of his prominent discoveries is the hippocampus. At that time, Arantius originated the term hippocampus, from the Greek word for seahorse (hippos ["horse"] and kampos ["sea monster"]). Arantius published his description of the hippocampus in 1587, in the first chapter of his work titled De Humano Foetu Liber. Numerous nomenclatures of this structure, including "white silkworm," "Ammon's horn," and "ram's horn" were proposed by different scholars at that time. However, the term hippocampus has become the most widely used in the literature.

    In the drawing of coitus by Leonardo da Vinci are pictured the contemporary hypotheses regarding this act. The authors analyze the mamillaruteral connection depicted by the artist and grow up to believe that this is a hypothetical kiveris vena, female vein described by Anatomist Master Nicolai Physicus from the Salerno School. The Hebrew roots were found in the name. The connection is described also by Mondino in The Anathomia. The same connection can be found in the picture of the pregnant woman in Fasciculus Medicinæ by Johannes De Ketham.

  14. Leonardo Da Vinci and stroke - vegetarian diet as a possible cause. (United States)

    Oztürk, Serefnur; Altieri, Marta; Troisi, Pina


    Leonardo da Vinci (April 15, 1452 to May 2, 1519) was an Italian Renaissance architect, musician, anatomist, inventor, engineer, sculptor, geometer, and painter. It has been gleaned from the many available historical documents that da Vinci was a vegetarian who respected and loved animals, and that he suffered from right hemiparesis in the last 5 years of his life. A vegetarian diet has both positive and negative influences on the cerebrovascular system. In this report, a possible relation between a vegetarian diet and stroke is discussed from various perspectives as related to Leonardo da Vinci's stroke. Copyright (c) 2010 S. Karger AG, Basel.

    Aubert, M G


    Arthur Van Gehuchten (1861-1914), Belgian anatomist and neurologist, professor at the Université catholique de Louvain, was an enthusiastic user of photography and a pioneer of medical cinematography. He used these techniques widely in order to illustrate his lectures, papers and his neurological textbook. His films and photographic plates are at the present time being studied and restored. The nitrate films are the oldest belgian films surviving. Neuroscientists have played a major role in the development of medical photography and cinematography and in the use of these techniques for clinical, research or didactic purposes.

  17. "A new lachrymal gland with an excretory duct in red and fallow deer" by Johann jacob Harder (1694): English translation and historical perspective. (United States)

    Hillenius, Willem J; Phillips, Darryl A; Rehorek, Susan J


    The Harderian gland is an enigmatic orbital gland that has been described for many tetrapods, although a consistent definition of this structure has remained elusive. In particular, an unambiguous distinction between the Harderian gland and the nictitans gland, which may both occur in the anterior aspect of the orbit of mammals, remains problematic. These glands were first distinguished in 1694 by Johann Jacob Harder, a Swiss physician and anatomist. To facilitate a renewed examination of the anatomical and developmental relationships of the anterior orbital glands, we review the historical context of Harder's discovery, and provide Harder's original Latin text as well as an English translation.

  18. Evaluation of spheno-occipital synchondrosis: A review of literature and considerations from forensic anthropologic point of view (United States)

    Krishan, Kewal; Kanchan, Tanuj


    Cranial sutures and synchondrosis have long been studied by forensic scientists, human anatomists, and anthropologists for estimation of age in different population groups. Observation of the closure of spheno-occipital synchondrosis has an important role to play in the estimation of age in the examination of unknown human remains when a skull is brought for examination. The present article reviews the studies conducted on the closure of spheno-occipital synchondrosis and presents a few valuable considerations that would be essential for carrying out research related to closure of spheno-occipital synchondrosis in humans.

    The Monros of the University of Edinburgh reigned over anatomy instruction for over a century. The last of these men, Monro Tertius, was the weaker teacher of the family but still contributed to the anatomical and surgical literature. Herein, we describe the life of Alexander Monro Tertius and his writings, particularly on childhood hydrocephalus. Monro Tertius will not be remembered as a great anatomist or teacher. However, he collected and published important books on his observations and those of others on hydrocephalus. These texts contained the knowledge of his era on this topic.

    Bell's palsy, named after the Scottish anatomist, Sir Charles Bell, is the most common acute mononeuropathy, or disorder affecting a single nerve, and is the most common diagnosis associated with facial nerve weakness/paralysis. In the past 2 years, both the American Academy of Neurology (AAN) and the American Academy of Otolaryngology-Head and Neck Surgery Foundation (AAO-HNSF) have published clinical practice guidelines aimed to improve the quality of care and outcomes for patients diagnosed with Bell's palsy. This commentary aims to address the similarities and differences in the scope and final recommendations made by each guideline development group.

    Today's neuroanatomical terminology has its origins in the Romans' way of life, in their civil and military house architecture, as well as in the fields of engineering and technology. Despite the fact that they did not know how the nervous system worked and what the role of each neuroanatomic structure was, over time, especially in Renaissance and early modern times, the anatomists sought descriptive names for the nervous structures they have identified by way of similarity with some ancient items. This study aims to briefly review the influence of Roman architecture, engineering, and technology on neuroanatomic nomenclature, the precursor of modern neuroanatomical terminology.

    Throughout the centuries, anatomists attempting to denominate the new structures they discovered have found inspiration in the civilization of ancient Rome and the clothing worn by its citizens. This aricle presents the origins of seven neuroanatomical terms, fimbria, velum, funiculus, lemniscus, corona, splenium, and cingulum, inspired by the clothing and jewellery of Roman women and the military attire of Roman soldiers. Thus, through their apparel, the Romans influenced the Terminologia Anatomica and "clothed" the structures of the brain and spinal cord, making them immortal. Clin.

  5. Anecdotes to the life and times of Sir Richard Owen (1804-1892) in Lancaster. (United States)

    Wessels, Q; Taylor, A M


    Sir Richard Owen, a Lancastrian, was a prominent biologist, comparative anatomist, geologist, palaeontologist and known for coining the term dinosaur. His expertise in anatomical dissection proved to be one of his biggest assets and aided his career progression at the Royal College of Surgeons and the Zoological Society. Owen's apprenticeship in Lancaster helped him to gain expertise in anatomy and anatomical dissection. The authors aim to provide some novel contextual background to his childhood in Lancaster, his affection for his hometown and his contribution to Lancaster's sanitary reform. The latter aspect of his scientific accomplishments is typically overlooked.

  6. Johann Gottlieb Walter (1734-1818) and the technical preparation of bones in an anatomical cabinet in the late eighteenth and nineteenth century. (United States)

    Monza, Francesca; Badino, Paola; Licata, Marta


    This study aims to analyze Johann Gottlieb Walter's biography (1734-1818), a German physician that specialized in human anatomy, who received an award of the Göttingen Royal Academy of Sciences. Here, we describe his technique of preparing bones for educational purposes through the comparison of other widely used techniques. The article also focuses on the great historical, scientific and didactic values of the anatomical preparations. In Europe during the eighteenth century the activity of some anatomists and physiologists, who were dedicated to the realization of anatomical preparations, testified the progress of medicine in the study of the human body, fundamental knowledge for physician training.

    Full Text Available In this article, based on the second book of Galen’s De placitis Hippocratis et Platonis, we analyze scientific method of the famous anatomist and philosopher. We discuss experimental, logical and philosophical argumentation that Galen employs in his proof that the rational part of the soul situated in human brain. We study his polemics with Chrysippus, who declares that the rational part of the soul is located in the heart, and conclude that the treatise by Galen sets the standards of scientific studies in antiquity, which combines medical, philosophical and moral components.

  10. Everard Home, John Hunter, and cutaneous horns: a historical review. (United States)

    Bondeson, J


    A cutaneous horn is a protrusion from the skin made up of cornified material. These horns can be derived from a variety of epidermal lesions, both benign and malignant. This historical article reviews a number of early instances of cutaneous horns, some reported in the 16th and 17th centuries. The Danish anatomist Thomas Bartholin was the first to have a correct theory of the ethiology of these horny growths, and the English surgeons John Hunter and Everard Home confirmed his findings in the late 18th century.

The works of Nicolas Steno considering anatomy of excretory glands, cardiac and skeletal muscles and brain white substance are presented in the context of antecedent development of anatomy, content of anatomical physiological Galen concept and in interrelationship with underlying works of number European anatomist of XVII century (William Harvey, Thomas Bartholin, Jan Swammerdam, Marcello Malpighi, Willis, etc.).

  12. From ancient to contemporary times: a concise history of incisional hernia repair. (United States)

    Sanders, D L; Kingsnorth, A N


    This historical review explores the origins of incisional hernia surgery. Resources from each significant historical time period were reviewed, namely ancient times, the Greco-Roman period, the Middle Ages and the dawn of the surgeon anatomist, and the modern era. Although incisional hernias only started to be widely reported in the literature in the early twentieth century, an awareness of the risk of incisional hernia formation dates back to ancient times. Sometimes, it is important to look back at the history and evolution of a topic to continue making positive advances in that field.

  13. Giovanni Battista Morgagni (1682-1771): father of pathologic anatomy and pioneer of modern medicine. (United States)

    Ghosh, Sanjib Kumar


    Giovanni Battista Morgagni (1682-1771) was an Italian anatomist who introduced the anatomo-clinical concept in medicine and established anatomy as the instrument to identify the seat and etiology of any disease. He was professor of anatomy at the prestigious University of Padua for more than 50 years. His first documented text in anatomy, Adversaria Anatomica was published in three volumes between 1706 and 1719. His accurate anatomical descriptions of human organs enhanced his reputation as the most famous anatomist of Europe during that period. Morgagni published the most important work of his life, the masterpiece in pathologic anatomy, De Sedibus, in 1761. The text is based on his pathologic observations from about 700 autopsy dissections of patients whom he had treated during their lifetime. De Sedibus provides the reader with a precise correlation between the anatomo-pathologic findings at post-mortem and the clinical symptoms of a disease observed during a lifetime. Morgagni's ability to integrate and synthesize information set him apart from his contemporaries, and his anatomo-clinical method was a major breakthrough in the history of medicine as it helped physicians to diagnose a disease, analyse the prognosis of that disease and prepare a management protocol for the same. His achievements led to the emergence of pathologic anatomy as an exact science and with him began modern medicine.

  14. The effectiveness of virtual and augmented reality in health sciences and medical anatomy. (United States)

    Moro, Christian; Štromberga, Zane; Raikos, Athanasios; Stirling, Allan


    Although cadavers constitute the gold standard for teaching anatomy to medical and health science students, there are substantial financial, ethical, and supervisory constraints on their use. In addition, although anatomy remains one of the fundamental areas of medical education, universities have decreased the hours allocated to teaching gross anatomy in favor of applied clinical work. The release of virtual (VR) and augmented reality (AR) devices allows learning to occur through hands-on immersive experiences. The aim of this research was to assess whether learning structural anatomy utilizing VR or AR is as effective as tablet-based (TB) applications, and whether these modes allowed enhanced student learning, engagement and performance. Participants (n = 59) were randomly allocated to one of the three learning modes: VR, AR, or TB and completed a lesson on skull anatomy, after which they completed an anatomical knowledge assessment. Student perceptions of each learning mode and any adverse effects experienced were recorded. No significant differences were found between mean assessment scores in VR, AR, or TB. During the lessons however, VR participants were more likely to exhibit adverse effects such as headaches (25% in VR P augmented reality as means to supplement lesson content in anatomical education.

  15. Anatomy education in occupational therapy curricula: Perspectives of practitioners in the United States. (United States)

    Schofield, Katherine A


    The study of human anatomy is an integral component in the education of future occupational therapists, yet there is a paucity of research that explores the anatomy needs of students and new practitioners. As a follow up from a pilot study that surveyed a small cohort of practicing therapists, this article aimed to determine occupational therapy (OT) practitioners' views on anatomy course structure and content deemed important to include in OT curricula, entry level practitioners' anatomy knowledge, and application of anatomy in current practice. A Likert scale and free text questionnaire was distributed to practicing occupational therapists across the United States. Fifty-four percent of the participants in this cohort favored a standalone course, as compared to 94% in the pilot study group. Anatomy course content areas were comparable across groups. Systems identified as essential to cover in an OT anatomy course included skeletal, muscular, and nervous. Regions included the upper limb, thorax/trunk, head and neck, and lower limb. Seventy percent of participants in both groups felt that entry-level practitioners had adequate anatomy knowledge; 30% did not. Practice areas requiring anatomy knowledge included assessment of joint movement, muscle strength, pain, and functional mobility. Qualitative analysis of free text response data revealed the importance of anatomy knowledge in OT assessment and intervention strategies, determining the impact of injury or disease on occupational performance, client safety, and communication with other health care professionals and families.

  16. [The intermaxillary bone and Goethe's Mephistopheles]. (United States)

    Hellmich, S; Hellmich, J


    The greatest anatomist of the second half of the 18th century was considered to be Petrus Camper from Holland. His theory - widespread as a dogma - stated that the anatomical difference between man and animal was the missing intermaxillary bone in man, this being the distinguishing feature between man and monkey. Against this theory Goethe set hs own reflections and observations, and on March 27th 1784 he found, by "reflection and coincidence", the intermaxillary bone in the human skull. In order to present his exciting discovery to the famous anatomist, he wanted to use as an intermediary his good friend Johann Heinrich Merck from Darmstadt who was in contact with Petrus Camper. But Merck delayed the requested forwarding of the manuscript, belittled Goethe and the significance of his treatise considerably in an accompanying letter, did not forward Camper's replies, and in the meantime even took advantage of Goethe's treatise for his own publications. It as only late that Goethe became aware of the scheming and mean behaviour of his "good friend", and he felt disappointed and betrayed by Merck. In Goethe's dramatic poem "Faust", Dr. Faust is confronted with the figure of Mephistopheles--the spirit who always plans evil and always denies. There is enough evidence to believe that the person of J. H. Merck can be recognized in this figure, and that Goethe's discovery of the human intermaxillary bone had its part in creating the figure of Mephistopheles as we know it today.

  17. Anatomical sciences: A foundation for a solid learning experience in dental technology and dental prosthetics. (United States)

    Bakr, Mahmoud M; Thompson, C Mark; Massadiq, Magdalena


    Basic science courses are extremely important as a foundation for scaffolding knowledge and then applying it in future courses, clinical situations as well as in a professional career. Anatomical sciences, which include tooth morphology, oral histology, oral embryology, and head and neck anatomy form a core part of the preclinical courses in dental technology programs. In this article, the importance and relevance of anatomical sciences to dental personnel with no direct contact with patients (dental technicians) and limited discipline related contact with patients (dental prosthetists) is highlighted. Some light is shed on the role of anatomical sciences in the pedagogical framework and its significance in the educational process and interprofessional learning of dental technicians and prosthetists using oral biology as an example in the dental curriculum. To conclude, anatomical sciences allow dental technicians and prosthetists to a gain a better insight of how tissues function, leading to a better understanding of diagnosis, comprehensive treatment planning and referrals if needed. Patient communication and satisfaction also increases as a result of this deep understanding of oral tissues. Anatomical sciences bridge the gap between basic science, preclinical, and clinical courses, which leads to a holistic approach in patient management. Finally, treatment outcomes are positively affected due to the appreciation of the macro and micro structure of oral tissues.

  18. Integrating anatomy training into radiation oncology residency: considerations for developing a multidisciplinary, interactive learning module for adult learners. (United States)

    Labranche, Leah; Johnson, Marjorie; Palma, David; D'Souza, Leah; Jaswal, Jasbir


    Radiation oncologists require an in-depth understanding of anatomical relationships for modern clinical practice, although most do not receive formal anatomy training during residency. To fulfill the need for instruction in relevant anatomy, a series of four multidisciplinary, interactive learning modules were developed for a cohort of radiation oncology and medical physics residents. Instructional design was based on established learning theories, with the intent of integrating knowledge of specific anatomical regions with radiology and radiation oncology practice. Each session included presentations by a radiologist and a radiation oncologist, as well as hands-on exploration of anatomical specimens with guidance from anatomists. Pre- and post-tests distributed during each session showed significant short-term knowledge retention. According to qualitative surveys and exit interviews, participants felt more comfort' with delineating structures, gross anatomy, and radiograph interpretation at the end of each session. Overall participant experience was positive, and the modules were considered effective for learning radiologic anatomy. Suggestions for future interventions include more time, increased clinical application, additional contouring practice and feedback, and improved coordination between each of the three disciplines. Results and conclusions from this study will be used to inform the design of a future multi-day national workshop for Canadian radiation oncology residents. © 2014 American Association of Anatomists.

  19. The murine lens: A model to investigate in vivo epithelial-mesenchymal transition. (United States)

    Shirai, Kumi; Tanaka, Sai-Ichi; Lovicu, Frank J; Saika, Shizuya


    Epithelial-mesenchymal transition (EMT) produces myofibroblasts that contribute to the formation of fibrotic tissue with an impairment of tissue homeostasis and functionality. The crystalline lens of the eye is a unique transparent and isolated tissue. The lens vesicle becomes isolated from the surface ectoderm, its cells are all contained as they line the inner surface of the lens capsule. Clinically the formation of fibrotic tissue by the lens epithelial cells causes a type of cataract or opacification and contraction of the lens capsule postcataract surgery. Production of EMT in the intact animal lens by using specific gene transfer to the lens or experimental lens injury has been shown to be a powerful tool to investigate EMT processes. It is not easy to uncover whether the origin of the myofibroblast is epithelial cell-derived or from other cell lineages in fibrotic tissues. However, myofibroblasts that appear in the crystalline lens pathology are totally derived from the lens epithelial cells for the reasons mentioned above. Here, we report on different animal models of lens EMT, using either transgenic approaches or injury to study the biological aspects of EMT.

  20. Measuring medical students' motivation to learning anatomy by cadaveric dissection. (United States)

    Abdel Meguid, Eiman M; Khalil, Mohammed K


    Motivation and learning are inter-related. It is well known that motivating learners is clearly a complex endeavor, which can be influenced by the educational program and the learning environment. Limited research has been conducted to examine students' motivation as a method to assess the effectiveness of dissection in medical education. This study aimed to assess and analyze students' motivation following their dissection experience. A 29-item survey was developed based on the Attention, Relevance, Confidence, and Satisfaction model of motivation. Descriptive statistics were undertaken to describe students' motivation to the dissection experience. T-test and ANOVA were used to compare differences in motivational scores between gender and educational characteristics of students. Dissection activities appear to promote students' motivation. Gender difference was statistically significant as males were more motivated by the dissection experience than females. Comparison between students with different knowledge of anatomy was also significantly different. The study is an important step in the motivational design to improve students' motivation to learn. The outcome of this study provides guidance to the selection of specific strategies to increase motivation by generating motivational strategies/tactics to facilitate learning.

  1. The impact of stereoscopic imagery and motion on anatomical structure recognition and visual attention performance. (United States)

    Remmele, Martin; Schmidt, Elena; Lingenfelder, Melissa; Martens, Andreas


    Gross anatomy is located in a three-dimensional space. Visualizing aspects of structures in gross anatomy education should aim to provide information that best resembles their original spatial proportions. Stereoscopic three-dimensional imagery might offer possibilities to implement this aim, though some research has revealed potential impairments that may result from observing stereoscopic visualizations, such as discomfort. However, possible impairments of working memory such as decreased visual attention performance due to applying this technology in gross anatomy education have not yet been investigated. Similarly, in gross anatomy education the impact of stereoscopic imagery on learners' recognition of anatomical-spatial relationships and the impact of different presentation formats have only been investigated in a small number of studies. In this study, the performance of 171 teacher trainees working on the anatomy of hearing was examined, either with non-stereoscopic or stereoscopic imagery. Static and dynamic picture presentations were applied. Overall, benefits for stereoscopic imagery on estimating anatomical-spatial relations were found. The performance on a visual attention test indicates that the impact of stereoscopic visualizations on the human cognitive system varies more from person to person compared to non-stereoscopic visualizations. In addition, combinations of temporarily moving pictures and stereoscopic imagery lead to decreased visual attention performance compared to combinations of moving pictures and non-stereoscopic imagery.

  2. Improvements in anatomy knowledge when utilizing a novel cyclical "Observe-Reflect-Draw-Edit-Repeat" learning process. (United States)

    Backhouse, Mark; Fitzpatrick, Michael; Hutchinson, Joseph; Thandi, Charankumal S; Keenan, Iain D


    Innovative educational strategies can provide variety and enhance student learning while addressing complex logistical and financial issues facing modern anatomy education. Observe-Reflect-Draw-Edit-Repeat (ORDER), a novel cyclical artistic process, has been designed based on cognitivist and constructivist learning theories, and on processes of critical observation, reflection and drawing in anatomy learning. ORDER was initially investigated in the context of a compulsory first year surface anatomy practical (ORDER-SAP) at a United Kingdom medical school in which a cross-over trial with pre-post anatomy knowledge testing was utilized and student perceptions were identified. Despite positive perceptions of ORDER-SAP, medical student (n = 154) pre-post knowledge test scores were significantly greater (P artistic preferences when using ORDER were not significantly different (P > 0.05) to those students without these characteristics. These findings will be of value to anatomy instructors seeking to engage students from diverse learning backgrounds in a research-led, innovative, time and cost-effective learning method, in the context of contrasting learning environments.

  3. A Longitudinal Study in Learning Preferences and Academic Performance in First Year Medical School. (United States)

    Hu, Yenya; Gao, Hong; Wofford, Marcia M; Violato, Claudio


    This is a longitudinal study of first year medical students that investigates the relationship between the pattern change of the learning preferences and academic performance. Using the visual, auditory, reading-writing, and kinesthetic inventory at the beginning of the first and second year for the same class, it was found that within the first year, 36% of the class remained unimodal (single) modality learners (SS), 14% changed from unimodal to multimodality learners (SM), 27% changed from multimodality to unimodal modality learners (MS) and 21% remained as multimodality learners (MM). Among the academic performance through subsequent didactic blocks from Clinical Anatomy, Cell and Subcellular Processes to Medical Neuroscience during first year, the SM group made more significant improvement compared to the SS group. Semi-structured interview results from the SM group showed that students made this transition between the Clinical Anatomy course and the middle of the Medical Neuroscience course, in an effort to improve their performance. This study suggests that the transition from unimodal to multimodality learning among academically struggling students improved their academic performance in the first year of medical school. Therefore, this may be considered as part of academic advising tools for struggling students to improve their academic performances.

  4. Juan Valverde de Hamusco's unauthorized reproduction of a brain dissection by Andreas Vesalius. (United States)

    Lanska, Douglas J; Lanska, John R


    The objective of the present work is to examine images of the brain dissection by Flemish-born anatomist Andreas Vesalius (1514-1564) as originally represented in the Fabrica (1543), and later copied without Vesalius' permission by Spanish anatomist Juan Valverde de Hamusco (c1525-c1587) in Historia de la composicion del cuerpo humano (1556). Illustrations of the brain dissection in the Fabrica were obtained in digital form, resized, and arranged in a comparable montage to that presented by Valverde. Computer manipulations were used to assess image correspondence. The Valverde illustrations are approximately half the size and are mirror images of those in the Fabrica, but otherwise show the same dissection stages, and identical transverse brain levels and structures. The Valverde illustrations lack shadowing and show minor variations in perspective and fine details (e.g., branching pattern of the middle meningeal artery) from those in the Fabrica. Craftsmen under the direction of Valverde copied the woodcut prints in the Fabrica in close but approximate form by freehand engraving onto copper plates. Differences in the sizes of the images, and in perspective and fine detail, preclude direct tracing of images as the means of copying. Because engravings are in effect "flipped over" to make further prints, subsequent prints made from Valverde's copperplate engravings are mirror images of the prints in Vesalius' Fabrica.

  5. Role of comprehension on performance at higher levels of Bloom's taxonomy: Findings from assessments of healthcare professional students. (United States)

    Verenna, Anne-Marie A; Noble, Kim A; Pearson, Helen E; Miller, Susan M


    The first four levels of Bloom's taxonomy were used to create quiz questions designed to assess student learning of the gross anatomy, histology, and physiology of the gastrointestinal (GI) system. Information on GI histology and physiology was presented to separate samples of medical, dental, and podiatry students in computer based tutorials where the information from the two disciplines was presented either separately or in an integrated fashion. All students were taught GI gross anatomy prior to this study by course faculty as part of the required curriculum of their respective program. Student responses to the quiz questions were analyzed to assess both the validity of Bloom's cumulative hierarchy and the effectiveness of an integrated curriculum. No statistically significant differences were found between quiz scores from students who received the integrated tutorial and from those who received the separate tutorials. Multiple regression analyses provided partial support for a cumulative hierarchy where scores on the lower levels of Bloom's taxonomy predicted scores on higher levels. Notably, in the majority of regression analyses, the comprehension score was the key foundational predictor for application and analysis scores. This study supports the suggestion that educators increase the number of comprehension level questions, even at the expense of knowledge level questions, in course assessments both to evaluate lower order cognitive skills and also as a predictor of success on questions requiring application and analysis levels of the higher order cognitive skills of Bloom's taxonomy.

  6. Climbing Bloom's taxonomy pyramid: Lessons from a graduate histology course. (United States)

    Zaidi, Nikki B; Hwang, Charles; Scott, Sara; Stallard, Stefanie; Purkiss, Joel; Hortsch, Michael


    Bloom's taxonomy was adopted to create a subject-specific scoring tool for histology multiple-choice questions (MCQs). This Bloom's Taxonomy Histology Tool (BTHT) was used to analyze teacher- and student-generated quiz and examination questions from a graduate level histology course. Multiple-choice questions using histological images were generally assigned a higher BTHT level than simple text questions. The type of microscopy technique (light or electron microscopy) used for these image-based questions did not result in any significant differences in their Bloom's taxonomy scores. The BTHT levels for teacher-generated MCQs correlated positively with higher discrimination indices and inversely with the percent of students answering these questions correctly (difficulty index), suggesting that higher-level Bloom's taxonomy questions differentiate well between higher- and lower-performing students. When examining BTHT scores for MCQs that were written by students in a Multiple-Choice Item Development Assignment (MCIDA) there was no significant correlation between these scores and the students' ability to answer teacher-generated MCQs. This suggests that the ability to answer histology MCQs relies on a different skill set than the aptitude to construct higher-level Bloom's taxonomy questions. However, students significantly improved their average BTHT scores from the midterm to the final MCIDA task, which indicates that practice, experience and feedback increased their MCQ writing proficiency.

  7. Remote histology learning from static versus dynamic microscopic images. (United States)

    Mione, Sylvia; Valcke, Martin; Cornelissen, Maria


    Histology is the study of microscopic structures in normal tissue sections. Curriculum redesign in medicine has led to a decrease in the use of optical microscopes during practical classes. Other imaging solutions have been implemented to facilitate remote learning. With advancements in imaging technologies, learning material can now be digitized. Digitized microscopy images can be presented in either a static or dynamic format. This study of remote histology education identifies whether dynamic pictures are superior to static images for the acquisition of histological knowledge. Test results of two cohorts of second-year Bachelor in Medicine students at Ghent University were analyzed in two consecutive academic years: Cohort 1 (n = 190) and Cohort 2 (n = 174). Students in Cohort 1 worked with static images whereas students in Cohort 2 were presented with dynamic images. ANCOVA was applied to study differences in microscopy performance scores between the two cohorts, taking into account any possible initial differences in prior knowledge. The results show that practical histology scores are significantly higher with dynamic images as compared to static images (F (1,361) = 15.14, P Association of Anatomists. © 2015 American Association of Anatomists.

  8. Time limits in testing: An analysis of eye movements and visual attention in spatial problem solving. (United States)

    Roach, Victoria A; Fraser, Graham M; Kryklywy, James H; Mitchell, Derek G V; Wilson, Timothy D


    Individuals with an aptitude for interpreting spatial information (high mental rotation ability: HMRA) typically master anatomy with more ease, and more quickly, than those with low mental rotation ability (LMRA). This article explores how visual attention differs with time limits on spatial reasoning tests. Participants were assorted to two groups based on their mental rotation ability scores and their eye movements were collected during these tests. Analysis of salience during testing revealed similarities between MRA groups in untimed conditions but significant differences between the groups in the timed one. Question-by-question analyses demonstrate that HMRA individuals were more consistent across the two timing conditions (κ = 0.25), than the LMRA (κ = 0.013). It is clear that the groups respond to time limits differently and their apprehension of images during spatial problem solving differs significantly. Without time restrictions, salience analysis suggests LMRA individuals attended to similar aspects of the images as HMRA and their test scores rose concomitantly. Under timed conditions however, LMRA diverge from HMRA attention patterns, adopting inflexible approaches to visual search and attaining lower test scores. With this in mind, anatomical educators may wish to revisit some evaluations and teaching approaches in their own practice. Although examinations need to evaluate understanding of anatomical relationships, the addition of time limits may induce an unforeseen interaction of spatial reasoning and anatomical knowledge.

  9. Guiding low spatial ability individuals through visual cueing: The dual importance of where and when to look. (United States)

    Roach, Victoria A; Fraser, Graham M; Kryklywy, James H; Mitchell, Derek G V; Wilson, Timothy D


    Research suggests that spatial ability may predict success in complex disciplines including anatomy, where mastery requires a firm understanding of the intricate relationships occurring along the course of veins, arteries, and nerves, as they traverse through and around bones, muscles, and organs. Debate exists on the malleability of spatial ability, and some suggest that spatial ability can be enhanced through training. It is hypothesized that spatial ability can be trained in low-performing individuals through visual guidance. To address this, training was completed through a visual guidance protocol. This protocol was based on eye-movement patterns of high-performing individuals, collected via eye-tracking as they completed an Electronic Mental Rotations Test (EMRT). The effects of guidance were evaluated using 33 individuals with low mental rotation ability, in a counterbalanced crossover design. Individuals were placed in one of two treatment groups (late or early guidance) and completed both a guided, and an unguided EMRT. A third group (no guidance/control) completed two unguided EMRTs. All groups demonstrated an increase in EMRT scores on their second test (P ability "where" to look early in training, better search approaches may be adopted, yielding improvements in spatial reasoning scores. It is proposed that visual guidance may be applied in spatial fields, such as STEMM (science, technology, engineering, mathematics and medicine), surgery, and anatomy to improve student's interpretation of visual content.

  10. Exploring anatomy and physiology using iPad applications. (United States)

    Chakraborty, Tandra R; Cooperstein, Deborah F


    This study examined the use of iPads with anatomy applications (apps) in the laboratory sections of the largest undergraduate course at the university, Anatomy and Physiology, serving more than 300 students. The majority of these students were nursing, exercise science/physical education and biology majors. With a student survey (student opinion) and student practicum grades as metrics, this study determined whether the introduction of this novel mobile technology improved student grades and aided the students in learning the course material. The results indicated that students' grades improved with the introduction of the iPads, and 78% of the students reported that the iPads facilitated their ability to learn the course material. There was a positive association between frequency of app use and standardized mastery of the course material, as students who used the apps more frequently scored higher and indicated that they felt as though they had learned the material more comprehensively. Owning or having an iPad at home did not have a significant effect on the learning of the material. The general consensus by students was that iPad anatomy apps should be used frequently to better develop student understanding of the course material.

  11. A gross anatomy flipped classroom effects performance, retention, and higher-level thinking in lower performing students. (United States)

    Day, Leslie J


    A flipped classroom is a growing pedagogy in higher education. Many research studies on the flipped classroom have focused on student outcomes, with the results being positive or inconclusive. A few studies have analyzed confounding variables, such as student's previous achievement, or the impact of a flipped classroom on long-term retention and knowledge transfer. In the present study, students in a Doctor of Physical Therapy program in a traditional style lecture of gross anatomy (n = 105) were compared to similar students in a flipped classroom (n = 112). Overall, students in the flipped anatomy classroom had an increase in semester average grades (P = 0.01) and performance on higher-level analytical questions (P flipped anatomy classroom performing at a higher level in kinesiology (P flipped anatomy class, outperformed their traditional anatomy class counterparts in anatomy semester grades (P flipped classroom may benefit lower performing student's knowledge acquisition and transfer to a greater degree than higher performing students.

  12. Do collaborative practical tests encourage student-centered active learning of gross anatomy? (United States)

    Green, Rodney A; Cates, Tanya; White, Lloyd; Farchione, Davide


    Benefits of collaborative testing have been identified in many disciplines. This study sought to determine whether collaborative practical tests encouraged active learning of anatomy. A gross anatomy course included a collaborative component in four practical tests. Two hundred and seven students initially completed the test as individuals and then worked as a team to complete the same test again immediately afterwards. The relationship between mean individual, team, and difference (between team and individual) test scores to overall performance on the final examination (representing overall learning in the course) was examined using regression analysis. The overall mark in the course increased by 9% with a decreased failure rate. There was a strong relationship between individual score and final examination mark (P learning occurring during the collaborative testing and that weaker students gained the benefit from team marks without significant active learning taking place. This negative outcome may be due to insufficient encouragement of the active learning strategies that were expected to occur during the collaborative testing process. An improved understanding of the efficacy of collaborative assessment could be achieved through the inclusion of questionnaire based data to allow a better interpretation of learning outcomes.

  13. Clinical anatomy research in a research-driven anatomy department. (United States)

    Jones, D Gareth; Dias, G J; Mercer, S; Zhang, M; Nicholson, H D


    Clinical anatomy is too often viewed as a discipline that reiterates the wisdom of the past, characterized more by description of what is known than by active investigation and critical analysis of hypotheses and ideas. Various misconceptions follow from an acceptance of this premise: the teaching of clinical anatomists is textbook based, there is no clinical anatomy research worthy of the name, and any research that does exist fails to utilize modern technology and does not stand comparison with serious biomedical research as found in cell and molecular biology. The aim of this paper is to challenge each of these contentions by reference to ongoing clinical research studies within this department. It is argued that all teaching (including that of clinical anatomy) should be research-informed and that the discipline of clinical anatomy should have at its base a vigorous research ethos driven by clinically related problems. In interacting with physicians, the role of the clinical anatomist should be to promulgate a questioning scientific spirit, with its willingness to test and challenge accepted anatomic dicta.

  14. The relationship between student engagement with online content and achievement in a blended learning anatomy course. (United States)

    Green, Rodney A; Whitburn, Laura Y; Zacharias, Anita; Byrne, Graeme; Hughes, Diane L


    Blended learning has become increasingly common in higher education. Recent findings suggest that blended learning achieves better student outcomes than traditional face-to-face teaching in gross anatomy courses. While face-to-face content is perceived as important to learning there is less evidence for the significance of online content in improving student outcomes. Students enrolled in a second-year anatomy course from the physiotherapy (PT), exercise physiology (EP), and exercise science (ES) programs across two campuses were included (n = 500). A structural equation model was used to evaluate the relationship of prior student ability (represented by grade in prerequisite anatomy course) and final course grade and whether the relationship was mediated by program, campus or engagement with the online elements of the learning management system (LMS; proportion of documents and video segments viewed and number of interactions with discussion forums). PT students obtained higher grades and were more likely to engage with online course materials than EP and ES students. Prerequisite grade made a direct contribution to course final grade (P Student learning outcomes in a blended anatomy course can be predicted the by level of engagement with online content.

  15. Effects of image-based and text-based active learning exercises on student examination performance in a musculoskeletal anatomy course. (United States)

    Gross, M Melissa; Wright, Mary C; Anderson, Olivia S


    Research on the benefits of visual learning has relied primarily on lecture-based pedagogy, but the potential benefits of combining active learning strategies with visual and verbal materials on learning anatomy has not yet been explored. In this study, the differential effects of text-based and image-based active learning exercises on examination performance were investigated in a functional anatomy course. Each class session was punctuated with an average of 12 text-based and image-based active learning exercises. Participation data from 231 students were compared with their examination performance on 262 questions associated with the in-class exercises. Students also rated the helpfulness and difficulty of the in-class exercises on a survey. Participation in the active learning exercises was positively correlated with examination performance (r = 0.63, P text-based exercises (P text-based exercises was not. Additionally, students reported that the active learning exercises were helpful for seeing images of key ideas (94%) and clarifying key course concepts (80%), and that the image-based exercises were significantly less demanding, less hard and required less effort than text-based exercises (P < 0.05). The findings confirm the positive effect of using images and active learning strategies on student learning, and suggest that integrating them may be especially beneficial for learning anatomy.

  16. Learning and study strategies correlate with medical students' performance in anatomical sciences. (United States)

    Khalil, Mohammed K; Williams, Shanna E; Gregory Hawkins, H


    Much of the content delivered during medical students' preclinical years is assessed nationally by such testing as the United States Medical Licensing Examination ® (USMLE ® ) Step 1 and Comprehensive Osteopathic Medical Licensing Examination ® (COMPLEX-USA ® ) Step 1. Improvement of student study/learning strategies skills is associated with academic success in internal and external (USMLE Step 1) examinations. This research explores the strength of association between the Learning and Study Strategies Inventory (LASSI) scores and student performance in the anatomical sciences and USMLE Step 1 examinations. The LASSI inventory assesses learning and study strategies based on ten subscale measures. These subscales include three components of strategic learning: skill (Information processing, Selecting main ideas, and Test strategies), will (Anxiety, Attitude, and Motivation) and self-regulation (Concentration, Time management, Self-testing, and Study aid). During second year (M2) orientation, 180 students (Classes of 2016, 2017, and 2018) were administered the LASSI survey instrument. Pearson Product-Moment correlation analyses identified significant associations between five of the ten LASSI subscales (Anxiety, Information processing, Motivation, Selecting main idea, and Test strategies) and students' performance in the anatomical sciences and USMLE Step 1 examinations. Identification of students lacking these skills within the anatomical sciences curriculum allows targeted interventions, which not only maximize academic achievement in an aspect of an institution's internal examinations, but in the external measure of success represented by USMLE Step 1 scores.

  17. Evaluation of an innovative hands-on anatomy-centered ultrasound curriculum to supplement graduate gross anatomy education. (United States)

    Royer, Danielle F; Kessler, Ross; Stowell, Jeffrey R


    Ultrasound (US) can enhance anatomy education, yet is incorporated into few non-medical anatomy programs. This study is the first to evaluate the impact of US training in gross anatomy for non-medical students in the United States. All 32 master's students enrolled in gross anatomy with the anatomy-centered ultrasound (ACUS) curriculum were recruited. Mean Likert ratings on pre- and post-course surveys (100% response rates) were compared to evaluate the effectiveness of the ACUS curriculum in developing US confidence, and gauge its impact on views of US. Post-course, students reported significantly higher (P curriculum in students with limited prior experience. Views on the value of US to anatomy education and to students' future careers remained positive after the course. End-of-semester quiz performance (91% response rate) provided data on educational outcomes. The average score was 79%, with a 90% average on questions about distinguishing tissues/artifacts, demonstrating positive learning outcomes and retention. The anatomy-centered ultrasound curriculum significantly increased confidence with and knowledge of US among non-medical anatomy students with limited prior training. Non-medical students greatly value the contributions that US makes to anatomy education and to their future careers. It is feasible to enhance anatomy education outside of medical training by incorporating US.

  18. Value of vaginal cervical position in estimating uterine anatomy. (United States)

    Fidan, Ulaş; Keskin, Uğur; Ulubay, Mustafa; Öztürk, Mustafa; Bodur, Serkan


    The anatomy of the uterus is defined with the angles of the vagina, cervix and uterine corpus. Hereunder there are angles of version and flexion. The cervical position observed during the vaginal speculum examination, may give information about the uterine anatomy. In this study, we investigated the place of the cervical position in the estimation of the uterine anatomy observed during the cervical examination. We enrolled 240 patients in our study, who applied to our routine gynecology outpatient clinic with various complaints. We divided these patients into two groups according to the cervical position (anterior cervical position and posterior cervical position) observed during the speculum examination. We recorded the uterine anatomy also with the transvaginal ultrasonography. During the speculum examination, we determined that 90% of the cases with posterior fornix position were anteverted and 10% retroverted; 64.2% of the cases with anterior fornix position were anteverted and 35.8% retroverted. According to these findings, cervical position observed during the speculum examination might be useful in the estimation of the uterine anatomy regarding the angles of the version. However, the ultrasonographic examination is essential for a definitive determination of the uterine anatomy. Clin. Anat. 30:404-408, 2017. © 2017 The Authors.

  19. Student performance on practical gross anatomy examinations is not affected by assessment modality. (United States)

    Meyer, Amanda J; Innes, Stanley I; Stomski, Norman J; Armson, Anthony J


    Anatomical education is becoming modernized, not only in its teaching and learning, but also in its assessment formats. Traditional "steeplechase" examinations are being replaced with online gross anatomy examinations. The aims of this study were to: (1) determine if online anatomy practical examinations are equivalent to traditional anatomy practical examinations; and (2) to examine if students' perceptions of the online or laboratory testing environments influenced their performance on the examinations. In phase one, 10 third-year students were interviewed to generate perception items to which five anatomy lecturers assigned content validity. In phase two, students' gross anatomical knowledge was assessed by examinations in two modes and their perceptions were examined using the devised survey instrument. Forty-five second-year chiropractic students voluntarily participated in Phase Two. The two randomly allocated groups completed the examinations in a sequential cross-over manner. Student performance on the gross anatomy examination was not different between traditional "steeplechase" (mean ± standard deviation (SD): 69 ± 11%) and online (68 ± 15%) modes. The majority of students (87%) agreed that they felt comfortable using computers for gross anatomy examinations. However, fewer students found it easy to orientate images of cadaver specimens online. The majority of students (85%) agreed that they felt comfortable working with cadavers but there was less agreement on the effect of moving around the laboratory during practical examinations. This data will allow anatomists to confidently implement online assessments without fear of jeopardizing academic rigor or student performance. © 2015 American Association of Anatomists.

  20. Online dissection audio-visual resources for human anatomy: Undergraduate medical students' usage and learning outcomes. (United States)

    Choi-Lundberg, Derek L; Cuellar, William A; Williams, Anne-Marie M


    In an attempt to improve undergraduate medical student preparation for and learning from dissection sessions, dissection audio-visual resources (DAVR) were developed. Data from e-learning management systems indicated DAVR were accessed by 28% ± 10 (mean ± SD for nine DAVR across three years) of students prior to the corresponding dissection sessions, representing at most 58% ± 20 of assigned dissectors. Approximately 50% of students accessed all available DAVR by the end of semester, while 10% accessed none. Ninety percent of survey respondents (response rate 58%) generally agreed that DAVR improved their preparation for and learning from dissection when used. Of several learning resources, only DAVR usage had a significant positive correlation (P = 0.002) with feeling prepared for dissection. Results on cadaveric anatomy practical examination questions in year 2 (Y2) and year 3 (Y3) cohorts were 3.9% (P learning outcomes of more students.

  1. Educational software usability: Artifact or Design? (United States)

    Van Nuland, Sonya E; Eagleson, Roy; Rogers, Kem A


    Online educational technologies and e-learning tools are providing new opportunities for students to learn worldwide, and they continue to play an important role in anatomical sciences education. Yet, as we shift to teaching online, particularly within the anatomical sciences, it has become apparent that e-learning tool success is based on more than just user satisfaction and preliminary learning outcomes-rather it is a multidimensional construct that should be addressed from an integrated perspective. The efficiency, effectiveness and satisfaction with which a user can navigate an e-learning tool is known as usability, and represents a construct which we propose can be used to quantitatively evaluate e-learning tool success. To assess the usability of an e-learning tool, usability testing should be employed during the design and development phases (i.e., prior to its release to users) as well as during its delivery (i.e., following its release to users). However, both the commercial educational software industry and individual academic developers in the anatomical sciences have overlooked the added value of additional usability testing. Reducing learner frustration and anxiety during e-learning tool use is essential in ensuring e-learning tool success, and will require a commitment on the part of the developers to engage in usability testing during all stages of an e-learning tool's life cycle.

  2. "Applying anatomy to something I care about": Authentic inquiry learning and student experiences of an inquiry project. (United States)

    Anstey, Lauren M


    Despite advances to move anatomy education away from its didactic history, there is a continued need for students to contextualize their studies to make learning more meaningful. This article investigates authentic learning in the context of an inquiry-based approach to learning human gross anatomy. Utilizing a case-study design with three groups of students (n = 18) and their facilitators (n = 3), methods of classroom observations, interviews, and artifact collection were utilized to investigate students' experiences of learning through an inquiry project. Qualitative data analysis through open and selective coding produced common meaningful themes of group and student experiences. Overall results demonstrate how the project served as a unique learning experience where learners engaged in the opportunity to make sense of anatomy in context of their interests and wider interdisciplinary considerations through collaborative, group-based investigation. Results were further considered in context of theoretical frameworks of inquiry-based and authentic learning. Results from this study demonstrate how students can engage anatomical understandings to inquire and apply disciplinary considerations to their personal lives and the world around them.

  3. The interrupted learner: How distractions during live and video lectures influence learning outcomes. (United States)

    Zureick, Andrew H; Burk-Rafel, Jesse; Purkiss, Joel A; Hortsch, Michael


    New instructional technologies have been increasingly incorporated into the medical school learning environment, including lecture video recordings as a substitute for live lecture attendance. The literature presents varying conclusions regarding how this alternative experience impacts students' academic success. Previously, a multi-year study of the first-year medical histology component at the University of Michigan found that live lecture attendance was positively correlated with learning success, while lecture video use was negatively correlated. Here, three cohorts of first-year medical students (N = 439 respondents, 86.6% response rate) were surveyed in greater detail regarding lecture attendance and video usage, focusing on study behaviors that may influence histology learning outcomes. Students who reported always attending lectures or viewing lecture videos had higher average histology scores than students who employed an inconsistent strategy (i.e., mixing live attendance and video lectures). Several behaviors were negatively associated with histology performance. Students who engaged in "non-lecture activities" (e.g., social media use), students who reported being interrupted while watching the lecture video, or feeling sleepy/losing focus had lower scores than their counterparts not engaging in these behaviors. This study suggests that interruptions and distractions during medical learning activities-whether live or recorded-can have an important impact on learning outcomes.

  4. Teaching surgical exposures to undergraduate medical students: an integration concept for anatomical and surgical education. (United States)

    Hammer, Niels; Hepp, Pierre; Löffler, Sabine; Schleifenbaum, Stefan; Steinke, Hanno; Klima, Stefan


    Decreasing numbers of students are interested in starting a surgical career, posing substantial challenges to patient care in the next years. The anatomy course is one of the key subjects in medical training, especially in surgical disciplines. Innovative teaching concepts that integrate surgically relevant anatomy and manual dexterity might help boost student interest in surgery. A preclinical workshop entitled "Surgical exposures" was developed. A team of anatomists and surgeons introduced the surgical exposures, demonstrating the procedures on Thiel-fixed body donors. Following this introduction, students practiced the exposures in an operating room-like manner. A six-point Likert scale was used to evaluate the workshop and to compare it to the first-year dissection course. The overall evaluation result for the surgical exposures was excellent, proving to be a significantly better result when compared to the first-year dissection course. The students were more satisfied with the teaching time invested by the peers and regarded the workshop as clinically highly relevant. Furthermore, they felt that questions were addressed better and that the overall atmosphere was better than in the gross anatomy course. Subject to criticism was the course size and practicing time in both cases. The surgical exposures workshop provides preclinical students with clinically relevant anatomy and manual dexterity. It may positively influence the decision to follow a surgical career. This course, however, requires extensive teaching resources. The given concept may help implement practical medical skills in the preclinical curriculum, strengthening the professional identity of surgeons and anatomists.

  5. Spatial abilities and anatomy knowledge assessment: A systematic review. (United States)

    Langlois, Jean; Bellemare, Christian; Toulouse, Josée; Wells, George A


    Anatomy knowledge has been found to include both spatial and non-spatial components. However, no systematic evaluation of studies relating spatial abilities and anatomy knowledge has been undertaken. The objective of this study was to conduct a systematic review of the relationship between spatial abilities test and anatomy knowledge assessment. A literature search was done up to March 20, 2014 in Scopus and in several databases on the OvidSP and EBSCOhost platforms. Of the 556 citations obtained, 38 articles were identified and fully reviewed yielding 21 eligible articles and their quality were formally assessed. Non-significant relationships were found between spatial abilities test and anatomy knowledge assessment using essays and non-spatial multiple-choice questions. Significant relationships were observed between spatial abilities test and anatomy knowledge assessment using practical examination, three-dimensional synthesis from two-dimensional views, drawing of views, and cross-sections. Relationships between spatial abilities test and anatomy knowledge assessment using spatial multiple-choice questions were unclear. The results of this systematic review provide evidence for spatial and non-spatial methods of anatomy knowledge assessment.

  6. How comprehensive are research studies investigating the efficacy of technology-enhanced learning resources in anatomy education? A systematic review. (United States)

    Clunie, Lauren; Morris, Neil P; Joynes, Viktoria C T; Pickering, James D


    Anatomy education is at the forefront of integrating innovative technologies into its curricula. However, despite this rise in technology numerous authors have commented on the shortfall in efficacy studies to assess the impact such technology-enhanced learning (TEL) resources have on learning. To assess the range of evaluation approaches to TEL across anatomy education, a systematic review was conducted using MEDLINE, the Educational Resources Information Centre (ERIC), Scopus, and Google Scholar, with a total of 3,345 articles retrieved. Following the PRISMA method for reporting items, 153 articles were identified and reviewed against a published framework-the technology-enhanced learning evaluation model (TELEM). The model allowed published reports to be categorized according to evaluations at the level of (1) learner satisfaction, (2) learning gain, (3) learner impact, and (4) institutional impact. The results of this systematic review reveal that most evaluation studies into TEL within anatomy curricula were based on learner satisfaction, followed by module or course learning outcomes. Randomized controlled studies assessing learning gain with a specific TEL resource were in a minority, with no studies reporting a comprehensive assessment on the overall impact of introducing a specific TEL resource (e.g., return on investment). This systematic review has provided clear evidence that anatomy education is engaged in evaluating the impact of TEL resources on student education, although it remains at a level that fails to provide comprehensive causative evidence.

  7. Medical student use of Facebook to support preparation for anatomy assessments. (United States)

    Pickering, James D; Bickerdike, Suzanne R


    The use of Facebook to support students is an emerging area of educational research. This study explored how a Facebook Page could support Year 2 medical (MBChB) students in preparation for summative anatomy assessments and alleviate test anxiety. Overall, Facebook analytics revealed that in total 49 (19.8% of entire cohort) students posted a comment in preparation for either the first (33 students) or second (34) summative anatomy assessments. 18 students commented in preparation for both. In total, 155 comments were posted, with 83 for the first and 72 for the second. Of the 83 comments, 45 related to checking anatomical information, 30 were requiring assessment information and 8 wanted general course information. For the second assessment this was 52, 14 and 6, respectively. Student perceptions on usage, and impact on learning and assessment preparation were obtained via a five-point Likert-style questionnaire, with 119 students confirming they accessed the Page. Generally, students believed the Page was an effective way to support their learning, and provided information which supported their preparation with increases in perceived confidence and reductions in anxiety. There was no difference between gender, except for males who appeared to be significantly less likely to ask a question as they may be perceived to lack knowledge (P Facebook can play an important role in supporting students in preparation for anatomy assessments.

  8. History of teaching anatomy in India: from ancient to modern times. (United States)

    Jacob, Tony George


    Safe clinical practice is based on a sound knowledge of the structure and function of the human body. Thus, knowledge of anatomy has been an essential tool in the practice of healthcare throughout the ages. The history of anatomy in India traces from the Paleolithic Age to the Indus Valley Civilization, the Vedic Times, the Islamic Dynasties, the modern Colonial Period, and finally to Independent India. The course of the study of anatomy, despite accompanying controversies and periods of latencies, has been fascinating. This review takes the reader through various periods of Indian medicine and the role of anatomy in the field of medical practice. It also provides a peek into the modern system of pedagogy in anatomical sciences in India. Copyright © 2013 American Association of Anatomists.

  9. From novice to master surgeon: improving feedback with a descriptive approach to intraoperative assessment. (United States)

    Huang, Emily; Wyles, Susannah M; Chern, Hueylan; Kim, Edward; O'Sullivan, Patricia


    A developmental and descriptive approach to assessing trainee intraoperative performance was explored. Semistructured interviews with 20 surgeon educators were recorded, transcribed, deidentified, and analyzed using a grounded theory approach to identify emergent themes. Two researchers independently coded the transcripts. Emergent themes were also compared to existing theories of skill acquisition. Surgeon educators characterized intraoperative surgical performance as an integrated practice of multiple skill categories and included anticipating, planning for contingencies, monitoring progress, self-efficacy, and "working knowledge." Comments concerning progression through stages, broadly characterized as "technician," "anatomist," "anticipator," "strategist," and "executive," formed a narrative about each stage of development. The developmental trajectory with narrative, descriptive profiles of surgeons working toward mastery provide a standardized vocabulary for communicating feedback, while fostering reflection on trainee progress. Viewing surgical performance as integrated practice rather than the conglomerate of isolated skills enhances authentic assessment. Copyright © 2015 Elsevier Inc. All rights reserved.

  10. Andreas Vesalius as a renaissance innovative neuroanatomist: his 5th centenary of birth. (United States)

    Andreas Vesalius (1514-1564) is considered the Father of Modern Anatomy, and an authentic representative of the Renaissance. His studies, founded on dissection of human bodies, differed from Galeno, who based his work on dissection of animals, constituted a notable scientific advance. Putting together science and art, Vesalius associated himself to artists of the Renaissance, and valued the images of the human body in his superb work De Humani Corporis Fabrica.This paper aims to honor this extraordinary European Renaissance physician and anatomist, who used aesthetic appeal to bind text and illustration, science and art. His achievements are highlighted, with an especial attention on neuroanatomy. Aspects about his personal life and career are also focused.

  12. Human cadavers Vs. multimedia simulation: A study of student learning in anatomy. (United States)

    Saltarelli, Andrew J; Roseth, Cary J; Saltarelli, William A


    Multimedia and simulation programs are increasingly being used for anatomy instruction, yet it remains unclear how learning with these technologies compares with learning with actual human cadavers. Using a multilevel, quasi-experimental-control design, this study compared the effects of "Anatomy and Physiology Revealed" (APR) multimedia learning system with a traditional undergraduate human cadaver laboratory. APR is a model-based multimedia simulation tool that uses high-resolution pictures to construct a prosected cadaver. APR also provides animations showing the function of specific anatomical structures. Results showed that the human cadaver laboratory offered a significant advantage over the multimedia simulation program on cadaver-based measures of identification and explanatory knowledge. These findings reinforce concerns that incorporating multimedia simulation into anatomy instruction requires careful alignment between learning tasks and performance measures. Findings also imply that additional pedagogical strategies are needed to support transfer from simulated to real-world application of anatomical knowledge. © 2014 American Association of Anatomists.

  13. Infraorbital nerve block within the Pterygopalatine fossa of the horse: anatomical landmarks defined by computed tomography

    International Nuclear Information System (INIS)

    Carsten, S.; Hagen, G.


    In order to provide anaesthesia of the equine maxillary cheek teeth, a local nerve block of the infraorbital nerve in the pterygopalatine fossa had been proposed, which is referred to as the 'Palatine Bone Insertion' (PBI). As several complications with this method were reported, our study was designed to recommend a modified injection technique which avoids the risk of puncturing of relevant anatomical structures. Five cadaver heads and two living horses were examined by contrast medium injections and subsequent computed tomography (CT). Spinal needles were inserted using two different insertion techniques: The above mentioned (PBI), and a modification called 'Extraperiorbital Fat Body Insertion' (EFBI). Both techniques (PBI and EFBI) provide a consistent distribution of contrast medium around the infraorbital nerve. However, only the EFBI technique is appropriate to minimize the risk of complications. This study is an example for the permanent challenge of anatomists to supply a basis for clinical and surgical procedures

  14. Archives of anatomy from the 17th to 21st century

    Directory of Open Access Journals (Sweden)

    Venkatesh Gokuldas Kamath


    Full Text Available The article provides an insight into the history of anatomy and anatomical teaching from the 17th to 21st century. A form of teaching that commenced by expressing the anatomical intricacy using paintings, sketches, and models evolved into museums with formalin-preserved specimens, corrosion casts, plastination, and finally culminating in the contemporary museums with electronic screens and audiovisual aids. Anatomical teaching has evolved with time from blackboard teaching to use of overhead projectors, imaging, demonstrations, and simulation. Anatomy is a science which, to be expressed in all its grandeur, requires a combined teamwork of anatomists, renowned artists, modelers, technicians, and computer experts. The latest three-dimensional viewing capabilities will certainly be applied to teaching anatomy in future. This will enable a medical student to understand anatomy more appropriately in all its dimensions.

  15. The influence of ancient Greek thought on fifteenth century anatomy: Galenic influence and Leonardo da Vinci. (United States)

    Tubbs, Richard Isaiah; Gonzales, Jocelyn; Iwanaga, Joe; Loukas, Marios; Oskouian, Rod J; Tubbs, R Shane


    Leonardo da Vinci (1452-1519) can be called one of the earliest contributors to the history of anatomy and, by extension, the study of medicine. He may have even overshadowed Andreas Vesalius (1514-1564), the so-called founder of human anatomy, if his works had been published within his lifetime. While some of the best illustrations of their time, with our modern knowledge of anatomy, it is clear that many of da Vinci's depictions of human anatomy are inaccurate. However, he also made significant discoveries in anatomy and remarkable predictions of facts he could not yet discover with the technology available to him. Additionally, da Vinci was largely influenced by Greek anatomists, as indicated from his ideas about anatomical structure. In this historical review, we describe da Vinci's history, influences, and discoveries in anatomical research and his depictions and errors with regards to the musculoskeletal system, cardiovascular system, nervous system, and other organs.

    Jacob Winslow was a Dutch born, French naturalized anatomist and physician whose contributions to medicine are abundant. His importance to medicine is undisputed. His personal life included a religious crisis that resulted in his estrangement from his family, but afforded him patrons in Paris to continue his work. Following this conversion, he changed his name to that of his catechist and was rechristened Jacques Benigne Wilson. His respect as an expert was well deserved, and he held several prominent positions during his career in Paris. His main work, Exposition anatomique de la structure du corps humain, was published in 1732 and is considered the first purely anatomical treatise. This review highlights his contributions to anatomy and medicine through the course of his career. © 2012 Wiley Periodicals, Inc.

  17. The history and the art of anatomy: a source of inspiration even nowadays. (United States)

    Mavrodi, Alexandra; Paraskevas, George; Kitsoulis, Panagiotis


    Ever since man started to study systematically medicine for the first time he recognized the value of the knowledge of Anatomy in order to safely cut and treat the human body. However, over the centuries it has been proved that Anatomy is more than just a scientific field of medicine. The fact that Anatomy requires the use of human cadavers as an object to study brought to the surface many moral issues, which adumbrated its turbulent past. Additionally, Anatomy and its inextricable element, illustration, has many times been a source of inspiration for both the anatomists and the artists. This paper aims on the one hand to provide a condensed overview of the history of Anatomy and on the other hand to investigate the way Anatomy penetrates Art and, conversely, Art penetrates Anatomy.

  18. Pioneering Studies on Cephalopod's Eye and Vision at the Stazione Zoologica Anton Dohrn (1883-1977). (United States)

    Dröscher, Ariane


    From the late nineteenth century onwards, the phenomena of vision and the anatomy and physiology of the eye of marine animals induced many zoologists, ethologists, physiologists, anatomists, biochemists, and ophthalmologists to travel to the Zoological Station in Naples. Initially, their preferred research objects were fish, but it soon became evident that cephalopods have features which make them particularly suited to research. After the first studies, which outlined the anatomical structure of cephalopods' eyes and optic nerves, the research rapidly shifted to the electrophysiology and biochemistry of vision. In the twentieth century these results were integrated with behavioral tests and training techniques. Between 1909 and 1913 also the well-known debate on color vision between ophthalmologist Carl von Hess and zoologist Karl von Frisch took place in Naples. Largely unknown is that the debate also concerned cephalopods. A comparative historical analysis of these studies shows how different experimental devices, theoretical frameworks, and personal factors gave rise to two diametrically opposing views.

  20. Art and the theatre of mind and body: how contemporary arts practice is re-framing the anatomo-clinical theatre (United States)

    Ingham, Karen


    The correspondences and disparities between how artists and anatomists view the body have historically been a source of creative collaboration, but how is this imaginative interdisciplinarity sustained and expressed in a contemporary context? In this review I suggest that contemporary artists engaging with the body, and the corresponding biomedical and architectural spaces where the body is investigated, are engendering innovative and challenging artworks that stimulate new relationships between art and anatomy. Citing a number of examples from key artists and referencing some of my own practice-based research, I posit that creative cross-fertilization provokes a discourse between mediated public perceptions of disease, death and the disposal of morbid remains, and the contemporary reality of biomedical practice. This is a dialogue that is complex, rich and diverse, and ultimately rewarding for both art and anatomy. PMID:19929908

  1. A history of forensic anthropology. (United States)

    Ubelaker, Douglas H


    Forensic anthropology represents a dynamic and rapidly evolving complex discipline within anthropology and forensic science. Academic roots extend back to early European anatomists but development coalesced in the Americas through high-profile court testimony, assemblage of documented collections and focused research. Formation of the anthropology section of the American Academy of Forensic Sciences in 1972, the American Board of Forensic Anthropology in 1977/1978 and other organizational advances provided important stimuli for progress. While early pioneers concentrated on analysis of skeletonized human remains, applications today have expanded to include complex methods of search and recovery, the biomechanics of trauma interpretation, isotopic analysis related to diet and region of origin, age estimation of the living and issues related to humanitarian and human rights investigations. © 2018 Wiley Periodicals, Inc.

  2. Cournand's and Richards' Post-Nobel Challenge: "Do Anything on the Structure of the Lung That Is of Interest for Physiology". (United States)

    Weibel, Ewald R


    In their Nobel Lectures of 1956, the two cardiopulmonary physiologists André Cournand and Dickinson Richards described the future projects that they considered important for rounding up their impressive scientific achievements. One of them called for work that brought together structure and function of the lung in a systematic way. They challenged a young anatomist to undertake this in their cardiopulmonary laboratory at Bellevue Hospital. The first steps established the need for quantitative information on the structures that form the pulmonary gas exchanger as well as the airway tree. This resulted in a new approach to lung anatomy: morphometry would provide the quantitative information for modeling structure-function relations in the lung, and eventually in the entire respiratory system, thus allowing a rational analysis of how structures affect or limit functions.

    Loukas, Marios; El-Sedfy, Abraham; Tubbs, R Shane; Gribben, Walter B; Shoja, Mohammadali M; Cermakova, Andrea


    Vincent Alexander Bochdalek, Czech anatomist and professor, was one of the pioneers in describing congenital diaphragmatic hernias in newborns. Interestingly, there is very little in the literature and almost nothing in the English literature regarding this important medical figure. A dedicated individual, Bochdalek had great perseverance, which allowed him to surpass obstacles in both his personal life and career. He is recognized for his accurate description of posterior diaphragmatic herniation, for which during his lifetime, there was no treatment. In addition, Bochdalek has multiple eponyms in his honor: ganglion Bochdalecki, Bochdalek's basket, and the valves of Bochdalek. Always steadfast in his beliefs, Bochdalek fought for the creation of anatomy labs in Prague against society pressures. His devoted study of anatomy, especially of congenital diaphragmatic hernias, laid the foundation for the successful surgical correction of this once lethal anomaly.

  4. [The anatomy Lesson of Dr. Nicolaes Tulp: The beginning of a medical utopia]. (United States)

    Rosler, Roberto; Young, Pablo


    The Anatomy Lesson of Dr. Nicolaes Tulp was painted by Rembrandt Harmen-szoon van Rijn at the early age of 26 years. In the XVII century these paintings were very popular in the Netherlands, and in this country the cities flourished as cultural centers searching the anatomy knowledge. Nicolaes Tulp was one of the persons in the center of Amsterdam's scene during XVII century. In 1632 Tulp was 39 years old, and he was an anatomist and a surgeon. Rembrandt masterly shows an autopsy performed by Dr. Tulp. This picture is the description of the beginning of a medical intellectual utopia: the absolute visibility of the disease. Unfortunately this utopia is blind to the complete visibility of the psycho-socio-cultural dimensions of the ill.

  5. Towards a Terminologia Neuroanatomica. (United States)

    This article deals with a recent revision of the terminology of the Sections Central Nervous System (CNS; Systema nervosum centrale) and Peripheral Nervous System (PNS; Systema nervosum periphericum) of the Terminologia Anatomica (TA, 1998) and the Terminologia Histologica (TH, 2008). These sections were extensively updated by the Federative International Programme for Anatomical Terminology (FIPAT) Working Group Neuroanatomy of the International Federation of Associations of Anatomists (IFAA). After extensive discussions by FIPAT, and consultation with the IFAA Member Societies, these parts were merged to form a Terminologia Neuroanatomica (TNA). After validation at the IFAA Executive Meeting, September 22, 2016, the TNA has been placed on the open part of the FIPAT website ( as the official FIPAT Terminology. This article outlines the major differences between the TNA and the TA. Clin. Anat. 30:145-155, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

  6. Nomenclature of the veins of the lower limbs: an international interdisciplinary consensus statement. (United States)

    Caggiati, Alberto; Bergan, John J; Gloviczki, Peter; Jantet, Gorges; Wendell-Smith, Colin P; Partsch, Hugo


    An agreement on anatomic terminology is the foundation for a common language in medical science and for an effective exchange of information. A thorough review of the literature has shown need for revision and extension of the official terminologia anatomica with regard to the veins of the lower limb. The foundation of this consensus document was laid by the faculty at a precongress meeting of The Fourteenth World Congress of the International Union of Phlebology (IUP), held in Rome on September 8-9, 2001, under the auspices of the IUP, the International Federation of Associations of Anatomists (IFAA), and the Federative International Committee on Anatomical Terminology (FICAT). The official names of some veins have been changed according to the guidelines of the FICAT. In addition, previously unnamed veins have received names relevant to their anatomy and clinical significance. Some of the terminology recommendations are innovative, but were judged to be correct by members of the committee.

  7. Anatomical terminology and nomenclature: past, present and highlights. (United States)

    Kachlik, David; Baca, Vaclav; Bozdechova, Ivana; Cech, Pavel; Musil, Vladimir


    The anatomical terminology is a base for medical communication. It is elaborated into a nomenclature in Latin. Its history goes back to 1895, when the first Latin anatomical nomenclature was published as Basiliensia Nomina Anatomica. It was followed by seven revisions (Jenaiensia Nomina Anatomica 1935, Parisiensia Nomina Anatomica 1955, Nomina Anatomica 2nd to 6th edition 1960-1989). The last revision, Terminologia Anatomica, (TA) created by the Federative Committee on Anatomical Terminology and approved by the International Federation of Associations of Anatomists, was published in 1998. Apart from the official Latin anatomical terminology, it includes a list of recommended English equivalents. In this article, major changes and pitfalls of the nomenclature are discussed, as well as the clinical anatomy terms. The last revision (TA) is highly recommended to the attention of not only teachers, students and researchers, but also to clinicians, doctors, translators, editors and publishers to be followed in their activities.

  8. Seeing patients and life contexts: the visual arts in medical education. (United States)

    Boisaubin, E V; Winkler, M G


    In many ways, the practice of medicine has been a visual science from the time of the early Renaissance anatomists to the high-speed scanners of today. But images of patients and their anatomical parts do not necessarily lead to an understanding of their problems. Meaning must follow the sensory experience and be coupled with reflection. The visual arts, therefore, can be used to help physicians in training increase their observational and interpretive skills. Works by classic and contemporary artists can be used to increase awareness of the complex nature of human beings and their conditions, which lie beneath the appearances. In addition to painting, television, motion pictures, and printed media may also be used in classroom settings to educate. Medical schools that do not have accessible fine arts or humanities programs may form allegiances with local artists to increase communication and understanding between these disciplines.

  9. Bone transplantation and tissue engineering, part I. Mythology, miracles and fantasy: from Chimera to the Miracle of the Black Leg of Saints Cosmas and Damian and the cock of John Hunter. (United States)

    Hernigou, Philippe


    The replacement of diseased organs and tissues by the healthy ones of others has been a unique milestone in modern medicine. However, even though cloning, member transplantation and regenerative therapies with stem cells are available in the twentieth and twenty-first centuries, one should remember that all these techniques were in the imagination more than 2,000 years ago. For centuries, transplantation remained a theme of mythology, miracle or fantasy and was found only in literature and arts. This first paper explains the concept of tissue transplantation from the period when it was relegated to the imagination to the work of the Scottish surgeon and anatomist, John Hunter, who demonstrated the viability of bone allograft.

  10. Oral anatomy in the sixteenth century: Juan Valverde de Amusco. (United States)

    López-Valverde, A; Gómez de Diego, R; De Vicente, J


    In 1554 Juan Valverde de Amusco, a Spanish anatomist, wrote the History of the composition of the human body, a complete anatomical treatise that took as its model the Vesalius school of thought (La fábrica of Vesalius). Considered one of the most complete anatomical treatises of the Renaissance and one of the most widely read books of the sixteenth century, it was translated into four languages in its day. The first chapter, devoted to bones, provides a meticulously detailed analysis of the bones of the facial structures and of the teeth, their supporting structures, vascularisation and innervation. Juan Valverde de Amusco even describes techniques for reducing mandibular luxations. Even with the imprecise observations typical of the time the treatise must be considered an exceptional document.

  11. Avicenna (AD 980 to 1037) and the care of the newborn infant and breastfeeding. (United States)

    Modanlou, H D


    A brief historical review of medicine during the fourth century Islamic civilization or eleventh century AD in Persia or Iran was undertaken with its focus on Avicenna. A physician-philosopher, named Ibn Sina or Avicenna (980 to 1037), followed and further expanded the tradition of western philosophy and medicine by Aristotle, Hippocrates and Galen. Avicenna, a physician, philosopher, astrologist, anatomist, pharmacologist, ethicist and poet wrote, the Canon of Medicine, the most comprehensive medical textbook of its time. This important textbook was extensively used in European medical schools for centuries after Avicenna's death. In the Canon of Medicine, a chapter is dedicated to the care of the newborn infant dealing with hygiene, breastfeeding and upbringing of the child.

  12. The ventricles of the brain in the N. American mink (Mustela vison (Brisson, 1756))

    Energy Technology Data Exchange (ETDEWEB)

    Goscicka, D.; Stankiewicz, W.; Szpinda, M. [Akademia Medyczna, Bydgoszcz (Poland)


    Using anatomical as well as radiographic and tomographic methods, sixty brains of the N. American mink were examined. It was found that the brain consists of four ventricles. Also, it was noted that the posterior horn was missing and that there was the olfactory recess present in the lateral ventricle, a large-size interthalamic connection present in the third ventricle, and a flat, necklace-like bottom in the fourth ventricle. Only recently, this ins and outs of the mink`s anatomical structure have begun to absorb anatomists. Apparently, it is related to the fact that furry animals, among them the mink, are being domesticated as if ``before our eyes``. For this reason and because of the easy access to material, examining of the brain ventricles in the mink was taken up. (author). 14 refs, 13 figs.

  14. Thinking like Leonardo da Vinci and its implications for the modern doctor. (United States)

    Baum, Neil


    Most people when asked to name the most creative, innovative, and multidimensional people in history would agree that Leonardo da Vinci is either at the top or very close to the number one position on that list. Wouldn't it be nice to think like da Vinci? This article shares the seven unique principles of thinking that da Vinci used that enabled him to be the greatest painter, sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist, cartographer, botanist, and writer of his (if not of all) time. This article will take you deep into the notebooks and codices of da Vinci, and suggest ways his ideas can be used by anyone in the healthcare profession to make them a better healthcare provider.

  15. Art and the theatre of mind and body: how contemporary arts practice is re-framing the anatomo-clinical theatre. (United States)

    Ingham, Karen


    The correspondences and disparities between how artists and anatomists view the body have historically been a source of creative collaboration, but how is this imaginative interdisciplinarity sustained and expressed in a contemporary context? In this review I suggest that contemporary artists engaging with the body, and the corresponding biomedical and architectural spaces where the body is investigated, are engendering innovative and challenging artworks that stimulate new relationships between art and anatomy. Citing a number of examples from key artists and referencing some of my own practice-based research, I posit that creative cross-fertilization provokes a discourse between mediated public perceptions of disease, death and the disposal of morbid remains, and the contemporary reality of biomedical practice. This is a dialogue that is complex, rich and diverse, and ultimately rewarding for both art and anatomy.

  16. Human Structure in Six and One-Half Weeks: One Approach to Providing Foundational Anatomical Competency in an Era of Compressed Medical School Anatomy curricula (United States)

    Halliday, Nancy; O'Donoghue, Daniel; Klump, Kathryn E; Thompson, Britta


    The University of Oklahoma College of Medicine reduced gross anatomy from a full semester, 130-hour course to a six and one-half week, 105-hour course as part of a new integrated systems-based pre-clinical curriculum. In addition to the reduction in contact hours, content from embryology, histology, and radiology were added into the course. The new curriculum incorporated best practices in the area of regular assessments, feedback, clinical application, multiple teaching modalities, and professionalism. A comparison of the components of the traditional and integrated curriculum, along with end of course evaluations and student performance revealed that the new curriculum was just as effective, if not more effective. This article also provides important lessons learned. Anat Sci Educ 8: 149–157. © 2014 The Authors. Published by Wiley Periodicals, Inc. on behalf of the American Association of Anatomists.

  17. Body symmetry and asymmetry in early Greek anatomical reasoning. (United States)

    Crivellato, Enrico; Ribatti, Domenico


    This historical note focuses on some of the earliest reports of human anatomy found in Greek medical literature. These passages testify the initial steps taken by Greek scientists in building a theoretical model of the human body. In these excerpts, one finds erroneous anatomical descriptions, which shed light on the epistemological approach used by these intellectual pioneers. Because of the lack of systematic dissection, it appears that early Greek anatomists developed a somewhat stylized idea of the human body that used a certain degree of symmetry. Overcoming the concept of a strict left-right bilateral parallelism in human body architecture was a challenging intellectual task that required prolonged observation of dissected corpses.

  18. The conquest of Addison's disease. (United States)

    Hiatt, J R; Hiatt, N


    A review of the understanding and treatment of adrenal insufficiency was undertaken to emphasize common themes in the history of endocrine disorders. Literature survey. The presence of the adrenal glands, initially ignored by anatomists, was first described by Eustachius and later confirmed by Casserius. Bartholin identified the glands as ductless. In 1855, Thomas Addison described the clinical syndrome of adrenal insufficiency. Medullary hormonal effects were described by Oliver and Shäfer in 1895; epinephrine was isolated by Takamini, and the secretory patterns were characterized by Cannon. Cortical function was elucidated by Biedl and Stewart and Rogoff, and the first cortical hormones were synthesized by Reichenstein. Hormonal replacement therapy paved the way for the first bilateral adrenalectomy, which was performed in 1950. This review underscores the historical themes in endocrine diseases: discovery of the glands, identification of their hormonal products, use of the hormones for therapy, and biosynthesis for pharmacologic applications.

  19. August Knoblauch and amusia: a nineteenth-century cognitive model of music. (United States)

    Johnson, Julene K; Graziano, Amy B


    Early models of human cognition can be traced to nineteenth-century investigations of brain and behavior. Influential neurologists such as Wernicke, Kussmaul, and Lichtheim constructed diagrammatic models to illustrate current theories of cognition. Language was the most commonly studied cognitive function during this time; however, investigators also studied other cognitive functions, such as music and visual processing. While a number of nineteenth-century neurologists made observations about music abilities in aphasic patients, August Knoblauch, a German physician and anatomist, was the first to propose a diagrammatic model of music (1888/1890). He described a detailed cognitive model of music processing, hypothesized the existence of nine disorders of music production and perception, and coined the term "amusia." Knoblauch's model is the earliest cognitive model of music and is largely unrecognized as an important part of the history of neurology, neuropsychology, and music cognition.

  20. Short history of the autopsy: part II. From the second half of the 16th century to contemporary times. (United States)

    Gulczyński, Jacek; Iżycka-Świeszewska, Ewa; Grzybiak, Marek


    We present the second part of our review concerning the history of autopsy. During the development of medicine the role of autopsy was obviously changing. Concurrently with the progress in the anatomical knowledge, the anatomists observed and noted both single anomalies and repetitive changes which correlated with symptoms in living patients. This is how anatomopathology came into being. We present the most famous people engaged in autopsy comprehension. We discuss main trends and ideas influencing the phenomenon of autopsy in the analyzed period: from sporadic public dissections, through theatra anatomica, introduction of autopsy to the hospital medicine and separation of anatomopathology as a medical speciality. The golden age of autopsy was the 19th century and the first half of the 20th century, with a consecutive decline in frequency. Nevertheless, despite the progress in diagnostics in vivo, it seems that autopsy will keep its important place in medicine according to the old motto "Mortui vivos docent" (the dead teach the living).

  1. Andreas Vesalius (1514-1564) - an unfinished life. (United States)

    Ambrose, Charles T


    The fame of Andreas Vesalius (1514-1564) rests on his anatomy text, De humani corporis fabrica, regarded as a seminal book in modern medicine. It was compiled while he taught anatomy at Padua, 1537-1543. Some of his findings challenged Galen's writings of the 2c AD, and caused De fabrica to be rejected immediately by classically trained anatomists. At age 29, Vesalius abandoned his studies and over the next two decades served as physician to Emperor Charles V of the Holy Roman Empire (HRE) and later to King Philip II of Spain in Madrid. In 1564, he sought to resume teaching anatomy in Padua, but release from royal service obliged him first to make a pilgrimage to Palestine. During the return voyage to Venice, he became ill and was put ashore alone on an Ionian island Zakynthos, where he died days later at age 50.

  2. An important Norwegian contribution to the study of the bursae of the upper and lower extremities (United States)


    We present a critical analysis of the monograph of A.S.D. Synnestvedt (1869) “En anatomisk beskrivelse af de paa over- og underestremiteterne forekommende Bursae mucosae”. The analysis was completed using anatomical information from the historically oldest publications dealing with the bursae of the extremities: Albinus (1734), Monro (1788), Rosenmüller (1799). We are of the opinion that Synnestvedt's publication is important, not only historically but also as a source of information for recent medical practitioners. Synnestvedt's monograph has a wealth of literary citations, unambiguous opinions of seasoned anatomists regarding the structure and function of the synovial membrane, and detailed descriptions of dissections he performed on fetal and adult cadavers. The information in this publication may enhance the diagnosis of bursopathies and enthesopathies of the extremities. PMID:20860444

  3. Variations in the origin and course of the suprascapular artery: case report and literature review

    Directory of Open Access Journals (Sweden)

    Rajani Singh


    Full Text Available Abstract The suprascapular artery is normally a branch of the thyrocervical trunk of the subclavian artery. During dissection of the left upper limb of a female cadaver, aged 70 years and fixed in 10% formalin solution, the suprascapular artery was observed aberrantly arising from the first part of the axillary artery. Later, it coursed obliquely behind the clavicle bone and brachial plexus to reach the suprascapular notch, where it was accompanied by the suprascapular nerve. Then, both suprascapular nerve and artery anomalously traversed beneath the transverse scapular ligament. It then irrigated the supraspinatus muscles and took part in the anastomosis around the scapula. On the contralateral side there was no abnormality. Variations in the origin and course of suprascapular artery are of immense value to orthopedic and vascular surgeons, angiographists, and anatomists.


    Directory of Open Access Journals (Sweden)



    Full Text Available OBJECTIVE: To study the variations in the origin of subscapular artery and its branches in the dissecting room. METHOD: The morphological study of 40 formalin fixed adult human cadavers of both sexes was carried out following a standard dissecting manual. OBSERVATION: Variations in origin of Subscapular artery was observed in 15% of the cadavers, origin from 2 nd part of axillary artery in 15%, as a common branch with Lateral thoracic artery in 10%, associated variations of posterior circumflex humeral artery, thoraco dorsal artery and circumflex scapular artery in 10%. CONCLUSION: In comparison with other similar studies, the present one also shows a near to equal scenario which helps us to strengthen the already existing knowledge. Appreciation of these variations is important to vascular surgeons for vascular graft surgeries, general and on co - surgeons while exposure of axilla and axillary artery so also to radiologists and anatomists

  5. The histopathologic reliability of tissue taken from cadavers within the gross anatomy laboratory. (United States)

    Rae, Guenevere; Newman, William P; McGoey, Robin; Donthamsetty, Supriya; Karpinski, Aryn C; Green, Jeffrey


    The purpose of this study was to examine the histopathologic reliability of embalmed cadaveric tissue taken from the gross anatomy laboratory. Tissue samples from hearts, livers, lungs, and kidneys were collected after the medical students' dissection course was completed. All of the cadavers were embalmed in a formalin-based fixative solution. The tissue was processed, embedded in paraffin, sectioned at six micrometers, and stained with H&E. The microscope slides were evaluated by a board certified pathologist to determine whether the cellular components of the tissues were preserved at a high enough quality to allow for histopathologic diagnosis. There was a statistically significant relationship between ratings and organ groups. Across all organs, there was a smaller proportion of "poor" ratings. The lung group had the highest percentage of "poor" ratings (23.1%). The heart group had the least "poor" ratings (0.0%). The largest percentage of "satisfactory" ratings were in the lung group (52.8%), and the heart group contained the highest percentage of "good" ratings (58.5%) The lung group had the lowest percentage of "good" ratings (24.2%). These results indicate that heart tissue is more reliable than lung, kidney, or liver tissue when utilizing tissue from the gross anatomy laboratory for research and/or educational purposes. This information advises educators and researchers about the quality and histopathologic reliability of tissue samples obtained from the gross anatomy laboratory.

  6. Understanding neurophobia: Reasons behind impaired understanding and learning of neuroanatomy in cross-disciplinary healthcare students. (United States)

    Javaid, Muhammad Asim; Chakraborty, Shelly; Cryan, John F; Schellekens, Harriët; Toulouse, André


    Recent studies have highlighted a fear or difficulty with the study and understanding of neuroanatomy among medical and healthcare students. This has been linked with a diminished confidence of clinical practitioners and students to manage patients with neurological conditions. The underlying reasons for this difficulty have been queried among a broad cohort of medical, dental, occupational therapy, and speech and language sciences students. Direct evidence of the students' perception regarding specific difficulties associated with learning neuroanatomy has been provided and some of the measures required to address these issues have been identified. Neuroanatomy is perceived as a more difficult subject compared to other anatomy topics (e.g., reproductive/pelvic anatomy) and not all components of the neuroanatomy curriculum are viewed as equally challenging. The difficulty in understanding neuroanatomical concepts is linked to intrinsic factors such as the inherent complex nature of the topic rather than outside influences (e.g., lecture duration). Participants reporting high levels of interest in the subject reported higher levels of knowledge, suggesting that teaching tools aimed at increasing interest, such as case-based scenarios, could facilitate acquisition of knowledge. Newer pedagogies, including web-resources and computer assisted learning (CAL) are considered important tools to improve neuroanatomy learning, whereas traditional tools such as lecture slides and notes were considered less important. In conclusion, it is suggested that understanding of neuroanatomy could be enhanced and neurophobia be decreased by purposefully designed CAL resources. This data could help curricular designers to refocus attention and guide educators to develop improved neuroanatomy web-resources in future.

  7. Soemmerring's work on the nervous system: a view on brain structure and function from the late eighteenth century. (United States)

    Hildebrand, R


    Samuel Thomas Soemmerring (1755-1830) was an encyclopaedic anatomist and one of the most experienced and renowned neuro-anatomists in the late eighteenth century. His description and illustration of the brainstem with its still accepted classification of cranial nerves (1778), the discovery of the acervulus in the epiphysis (1785), his demonstration of the crossing of the optic nerve fibres (1788), and of the macula lutea in the retina of the eye he had discovered in 1791, won him great recognition. Probably, unaware of Francesco Gennari's (1750-1797) and Félix Vicq d'Azyr's (1748-1794) observation, Soemmerring in the final years of the eighteenth century saw the broad white line running through the calcarine cortex of the occipital lobe. Soemmerring's comprehensive textbooks on the nervous system Vom Hirn and Rückenmark, 1788/1792, and Hirn- und Nervenlehre as part of his anatomical handbook Vom Baue des menschlichen Körpers, 1791/2nd edn, 1800, comprise all the knowledge in the field of neuro-anatomy at his time. Although the structure-function relationships mentioned are generally hypothetical, Soemmerring was convinced that mental faculties are executed in certain brain regions. In his treatise Uber das Organ der Seele, 1796, he localized the functions of the soul within the cerebrospinal fluid, which should come into close contact with the demonstrated and presumed nerve endings in the walls of the ventricular cavities. This last attempt of a synthesis of anatomy and metaphysics provoked passionate discussions and was criticised for epistemological reasons. Nevertheless, Soemmerring had moved the brain into the centre of the science of man what led to far-reaching consequences in the complexity of the discourse about man.

  8. Measuring the impact of the flipped anatomy classroom: The importance of categorizing an assessment by Bloom's taxonomy. (United States)

    Morton, David A; Colbert-Getz, Jorie M


    The flipped classroom (FC) model has emerged as an innovative solution to improve student-centered learning. However, studies measuring student performance of material in the FC relative to the lecture classroom (LC) have shown mixed results. An aim of this study was to determine if the disparity in results of prior research is due to level of cognition (low or high) needed to perform well on the outcome, or course assessment. This study tested the hypothesis that (1) students in a FC would perform better than students in a LC on an assessment requiring higher cognition and (2) there would be no difference in performance for an assessment requiring lower cognition. To test this hypothesis the performance of 28 multiple choice anatomy items that were part of a final examination were compared between two classes of first year medical students at the University of Utah School of Medicine. Items were categorized as requiring knowledge (low cognition), application, or analysis (high cognition). Thirty hours of anatomy content was delivered in LC format to 101 students in 2013 and in FC format to 104 students in 2014. Mann Whitney tests indicated FC students performed better than LC students on analysis items, U = 4243.00, P = 0.030, r = 0.19, but there were no differences in performance between FC and LC students for knowledge, U = 5002.00, P = 0.720 or application, U = 4990.00, P = 0.700, items. The FC may benefit retention when students are expected to analyze material. Anat Sci Educ 10: 170-175. © 2016 American Association of Anatomists. © 2016 American Association of Anatomists.

  9. The "flipped classroom" approach: Stimulating positive learning attitudes and improving mastery of histology among medical students. (United States)

    Cheng, Xin; Ka Ho Lee, Kenneth; Chang, Eric Y; Yang, Xuesong


    Traditional medical education methodologies have been dramatically impacted by the introduction of new teaching approaches over the past few decades. In particular, the "flipped classroom" format has drawn a great deal of attention. However, evidence regarding the effectiveness of the flipped model remains limited due to a lack of outcome-based studies. In the present study, a pilot histology curriculum of the organ systems was implemented among 24 Traditional Chinese Medicine (TCM) students in a flipped classroom format at Jinan University. As a control, another 87 TCM students followed a conventional histology curriculum. The academic performance of the two groups was compared. In addition, a questionnaire was administered to the flipped classroom group. The test scores for the flipped classroom participants were found to be significantly higher compared to non-participants in the control group. These results suggest that students may benefit from using the flipped classroom format. Follow-up questionnaires also revealed that most of the flipped classroom participants undertook relatively more earnest preparations before class and were actively involved in classroom learning activities. The teachers were also found to have more class time for leading discussions and delivering quizzes rather than repeating rote didactics. Consequently, the increased teaching and learning activities contributed to a better performance among the flipped classroom group. This pilot study suggests that a flipped classroom approach can be used to improve histology education among medical students. However, future studies employing randomization, larger numbers of students, and more precise tracking methods are needed before definitive conclusions can be drawn.

  10. Impact of introduction of blended learning in gross anatomy on student outcomes. (United States)

    Green, Rodney A; Whitburn, Laura Y


    Blended learning has become increasingly common, in a variety of disciplines, to take advantage of new technology and potentially increase the efficiency and flexibility of delivery. This study aimed to describe blended delivery of a gross anatomy course and to evaluate the effectiveness of the delivery in terms of student outcomes. A gross anatomy course for second-year physiotherapy students across two campuses was delivered in traditional face-to-face teaching mode in 2013 (n = 150 students), some online content was introduced in 2014 (n = 160) and the subject was fully blended in 2015 (n = 151). The final 'blend' consisted of one lecture per week with most content delivered using online video resources (prepared by staff using a structured peer-reviewed process) and retention of face-to-face practical classes. Outcomes evaluated included student grades, student engagement with content through online discussion forums and student feedback using both quantitative and qualitative analysis. Grades were higher in 2014 and 2015 than in 2013 (P online discussion forums. Student feedback identified some negative comments and lower levels of intellectual stimulation (P introduction of online content in 2014. The fully blended version in 2015 resulted in more balanced comments about online content but higher perceived workload (P learning. Blended learning appears to be well-suited to gross anatomy teaching on the proviso that face-to-face practical classes are maintained, but may result in higher perceived workloads.

  11. Properties of publications on anatomy in medical education literature. (United States)

    Vorstenbosch, Marc; Bolhuis, Sanneke; van Kuppeveld, Sascha; Kooloos, Jan; Laan, Roland


    Publications on anatomy in medical education appear to be largely anecdotal. To explore this, we investigated the literature on anatomy in medical education, aiming first to evaluate the contribution of the literature on anatomy in medical education to "best evidence medical education" (BEME) and second to evaluate the development of this literature toward more "best evidence" between 1985 and 2009. Four databases were searched for publications on anatomy in medical education published between 1985 and 2009, resulting in 525 references. Hundred publications were characterized by five variables (journal category, paper subject, paper category, author perspective, and paper perspective). Statements from these publications were characterized by two variables (category and foundation). The publications contained 797 statements that involved the words "anatomy," "anatomical," or "anatomist." Forty-five percent of the publications contained no explicit research question. Forty percent of the statements made were about "teaching methods" and 17% about "teaching content," 8% referred to "practical value," and 10% to "side effects" of anatomy education. Ten percent of the statements were "positional," five percent "traditional," four percent "self-evident," and two percent referred to "quality of care." Fifty-six percent of the statements had no foundation, 17% were founded on empirical data, and 27% by references. These results substantiated the critical comments about the anecdotal nature of the literature. However, it is encouraging to see that between 1985 and 2009 the number of publications is rising that these publications increasingly focus on teaching methods and that an academic writing style is developing. This suggests a growing body of empirical literature about anatomy education. Copyright © 2011 American Association of Anatomists.

  12. Evaluation by medical students of the educational value of multi-material and multi-colored three-dimensional printed models of the upper limb for anatomical education. (United States)

    Mogali, Sreenivasulu Reddy; Yeong, Wai Yee; Tan, Heang Kuan Joel; Tan, Gerald Jit Shen; Abrahams, Peter H; Zary, Nabil; Low-Beer, Naomi; Ferenczi, Michael Alan


    For centuries, cadaveric material has been the cornerstone of anatomical education. For reasons of changes in curriculum emphasis, cost, availability, expertise, and ethical concerns, several medical schools have replaced wet cadaveric specimens with plastinated prosections, plastic models, imaging, and digital models. Discussions about the qualities and limitations of these alternative teaching resources are on-going. We hypothesize that three-dimensional printed (3DP) models can replace or indeed enhance existing resources for anatomical education. A novel multi-colored and multi-material 3DP model of the upper limb was developed based on a plastinated upper limb prosection, capturing muscles, nerves, arteries and bones with a spatial resolution of ∼1 mm. This study aims to examine the educational value of the 3DP model from the learner's point of view. Students (n = 15) compared the developed 3DP models with the plastinated prosections, and provided their views on their learning experience using 3DP models using a survey and focus group discussion. Anatomical features in 3DP models were rated as accurate by all students. Several positive aspects of 3DP models were highlighted, such as the color coding by tissue type, flexibility and that less care was needed in the handling and examination of the specimen than plastinated specimens which facilitated the appreciation of relations between the anatomical structures. However, students reported that anatomical features in 3DP models are less realistic compared to the plastinated specimens. Multi-colored, multi-material 3DP models are a valuable resource for anatomical education and an excellent adjunct to wet cadaveric or plastinated prosections.

  13. Anatomical instruction and training for professionalism from the 19th to the 21st centuries. (United States)

    Warner, John Harley; Rizzolo, Lawrence J


    For most of the 19th century, anatomists in the United States saw the affective, emotional aspects of human dissection as salient ingredients in professional formation. Professionalism (or "character") signified medical integrity and guaranteed correct professional conduct. As gross anatomy came under siege in the late-19th and early-20th centuries, crowded out of medical curricula by the new experimental sciences, medical educators rethought what it was that dissecting a human body stood to give medical students. As they embraced a new understanding of professionalism premised on an allegiance to science, anatomists celebrated the habits of mind and sensibility to scientific investigation that could be acquired at the dissecting table. One consequence was a deliberate distancing of gross anatomy from the "art of medicine," and with it a de facto suppression of attention to the affective components of human dissection. During this period in the opening decades of the 20th century, the norm of silence about the emotional dimensions of dissection was set in place. The confluence of various movements by the 1960s and 1970s both revived attention to the emotional experience of dissection and sparked a renewed discussion about the relationship between the affective components of learning anatomy and the professional formation of future healers. There is a need to balance the tension between the "affective" and "scientific" aspects of anatomy, and by extension the tension between the "art" and "science" of medical practice. One method is to use small-group "learning societies" as a means to cultivate and meld both dimensions of the professional ethic. Copyright (c) 2006 Wiley-Liss, Inc.

  14. Novel dissection of the central nervous system to bridge gross anatomy and neuroscience for an integrated medical curriculum. (United States)

    Hlavac, Rebecca J; Klaus, Rachel; Betts, Kourtney; Smith, Shilo M; Stabio, Maureen E


    Medical schools in the United States continue to undergo curricular change, reorganization, and reformation as more schools transition to an integrated curriculum. Anatomy educators must find novel approaches to teach in a way that will bridge multiple disciplines. The cadaveric extraction of the central nervous system (CNS) provides an opportunity to bridge gross anatomy, neuroanatomy, and clinical neurology. In this dissection, the brain, brainstem, spinal cord, cauda equina, optic nerve/tract, and eyes are removed in one piece so that the entire CNS and its gateway to the periphery through the spinal roots can be appreciated. However, this dissection is rarely, if ever, performed likely due to time constraints, perceived difficulty, and lack of instructions. The goals of this project were (i) to provide a comprehensive, step-by-step guide for an en bloc CNS extraction and (ii) to determine effective strategies to implement this dissection/prosection within modern curricula. Optimal dissection methods were determined after comparison of various approaches/tools, which reduced dissection time from approximately 10 to 4 hours. The CNS prosections were piloted in small group sessions with two types of learners in two different settings: graduate students studied wet CNS prosections within the dissection laboratory and medical students used plastinated CNS prosections to review clinical neuroanatomy and solve lesion localization cases during their neurology clerkship. In both cases, the CNS was highly rated as a teaching tool and 98% recommended it for future students. Notably, 90% of medical students surveyed suggested that the CNS prosection be introduced prior to clinical rotations.

  15. Use of 3D printed models in medical education: A randomized control trial comparing 3D prints versus cadaveric materials for learning external cardiac anatomy. (United States)

    Lim, Kah Heng Alexander; Loo, Zhou Yaw; Goldie, Stephen J; Adams, Justin W; McMenamin, Paul G


    Three-dimensional (3D) printing is an emerging technology capable of readily producing accurate anatomical models, however, evidence for the use of 3D prints in medical education remains limited. A study was performed to assess their effectiveness against cadaveric materials for learning external cardiac anatomy. A double blind randomized controlled trial was undertaken on undergraduate medical students without prior formal cardiac anatomy teaching. Following a pre-test examining baseline external cardiac anatomy knowledge, participants were randomly assigned to three groups who underwent self-directed learning sessions using either cadaveric materials, 3D prints, or a combination of cadaveric materials/3D prints (combined materials). Participants were then subjected to a post-test written by a third party. Fifty-two participants completed the trial; 18 using cadaveric materials, 16 using 3D models, and 18 using combined materials. Age and time since completion of high school were equally distributed between groups. Pre-test scores were not significantly different (P = 0.231), however, post-test scores were significantly higher for 3D prints group compared to the cadaveric materials or combined materials groups (mean of 60.83% vs. 44.81% and 44.62%, P = 0.010, adjusted P = 0.012). A significant improvement in test scores was detected for the 3D prints group (P = 0.003) but not for the other two groups. The finding of this pilot study suggests that use of 3D prints do not disadvantage students relative to cadaveric materials; maximally, results suggest that 3D may confer certain benefits to anatomy learning and supports their use and ongoing evaluation as supplements to cadaver-based curriculums.

    Advances in three-dimensional (3D) printing allow for digital files to be turned into a "printed" physical product. For example, complex anatomical models derived from clinical or pre-clinical X-ray computed tomography (CT) data of patients or research specimens can be constructed using various printable materials. Although 3D printing has the potential to advance learning, many academic programs have been slow to adopt its use in the classroom despite increased availability of the equipment and digital databases already established for educational use. Herein, a protocol is reported for the production of enlarged bone core and accurate representation of human sinus passages in a 3D printed format using entirely consumer-grade printers and a combination of free-software platforms. The comparative resolutions of three surface rendering programs were also determined using the sinuses, a human body, and a human wrist data files to compare the abilities of different software available for surface map generation of biomedical data. Data shows that 3D Slicer provided highest compatibility and surface resolution for anatomical 3D printing. Generated surface maps were then 3D printed via fused deposition modeling (FDM printing). In conclusion, a methodological approach that explains the production of anatomical models using entirely consumer-grade, fused deposition modeling machines, and a combination of free software platforms is presented in this report. The methods outlined will facilitate the incorporation of 3D printed anatomical models in the classroom.

  17. The integration of brain dissection within the medical neuroscience laboratory enhances learning. (United States)

    Rae, Guenevere; Cork, R John; Karpinski, Aryn C; Swartz, William J


    The purpose of this study was to design a one-hour brain dissection protocol for a medical neuroscience course and evaluate the short and long-term effects of its implementation on medical students. First-year medical students (n = 166) participated in a brain dissection activity that included dissection of the basal nuclei and associated deep brain structures. Short-term retention was assessed by administering identical pre- and post-activity tests involving identification of brain structures. Following the brain dissection, the students' posttest scores were significantly higher (68.8% ± 17.8%; mean percent score ± SD) than their pretest scores (35.8% ± 20.0%) (P ≤ 0.0001). Long-term retention was evaluated by conducting an identical assessment five months after completion of the course. Students who participated in the dissection activity (n = 80) had significantly higher scores (46.6% ± 23.8%) than the students who did not participate in the dissection activity (n = 85) (38.1% ± 23.9%) (P ≤ 0.05). In addition to the long-term retention assessment, the NBME ® Subject Examination scores of students who participated in the dissection activity were significantly higher than the students who did not participate in the dissection activity (P ≤ 0.01). Results suggest that this succinct brain dissection activity may be a practical addition to an undergraduate medical neuroscience course for increasing the effectiveness of neuroanatomy training. This effect may have long-term benefits on knowledge retention and may be correlated with higher performance levels on standardized subject examinations.

  18. [Beginning of modern anatomy in Japan from the perspective of anatomical bibliographies of the Meiji era]. (United States)

    Shimada, Kazuyuki


    In contrast to the days of the Shogunate during the Edo period when knowledge and information from abroad were derived solely from The Netherlands (so-called Western learning), the establishment of the new Meiji government marked the arrival of a wealth of new knowledge from English and German speaking countries to Japan. As with other academic fields, the field of medicine, particularly anatomy, experienced an influx of many foreign books during this period. In the early to middle Meiji period (1868-1887), anatomy books from English-speaking countries became mainstream, and translations of these books were subsequently published. However, following Japan's decision in the third year of the Meiji era (1870) to model itself after German medicine, and the subsequent introduction of German teachers in Japanese medical education, medicine from English-speaking countries was gradually replaced by German medicine. Consequently, a multitude of German anatomy textbooks began to be imported into Japan during the middle Meiji period. In the later half of Meiji period (1888-1912), sequential publication of books written by Japanese anatomists based on German anatomy books became more common, along with the development of medical personnel who had been taught by foreign teachers. Most of the anatomy textbooks written by Japanese anatomists followed a format based on that of German anatomy textbooks of the time. This format style became well established by the late the end of Meiji period, and continued to be used in subsequently published anatomy textbooks until around the end of World War II. Here we introduce books, such as the translated anatomy books and textbooks, that were published during the turbulent Meiji era, and describe these within a bibliographical context.

  19. Using generalizability analysis to estimate parameters for anatomy assessments: A multi-institutional study. (United States)

    Byram, Jessica N; Seifert, Mark F; Brooks, William S; Fraser-Cotlin, Laura; Thorp, Laura E; Williams, James M; Wilson, Adam B


    With integrated curricula and multidisciplinary assessments becoming more prevalent in medical education, there is a continued need for educational research to explore the advantages, consequences, and challenges of integration practices. This retrospective analysis investigated the number of items needed to reliably assess anatomical knowledge in the context of gross anatomy and histology. A generalizability analysis was conducted on gross anatomy and histology written and practical examination items that were administered in a discipline-based format at Indiana University School of Medicine and in an integrated fashion at the University of Alabama School of Medicine and Rush University Medical College. Examination items were analyzed using a partially nested design s×(i:o) in which items were nested within occasions (i:o) and crossed with students (s). A reliability standard of 0.80 was used to determine the minimum number of items needed across examinations (occasions) to make reliable and informed decisions about students' competence in anatomical knowledge. Decision study plots are presented to demonstrate how the number of items per examination influences the reliability of each administered assessment. Using the example of a curriculum that assesses gross anatomy knowledge over five summative written and practical examinations, the results of the decision study estimated that 30 and 25 items would be needed on each written and practical examination to reach a reliability of 0.80, respectively. This study is particularly relevant to educators who may question whether the amount of anatomy content assessed in multidisciplinary evaluations is sufficient for making judgments about the anatomical aptitude of students.

  20. Learning anatomy through Thiel- vs. formalin-embalmed cadavers: Student perceptions of embalming methods and effect on functional anatomy knowledge. (United States)

    Kennel, Larissa; Martin, David M A; Shaw, Hannah; Wilkinson, Tracey


    Thiel-embalmed cadavers, which have been adopted for use in anatomy teaching in relatively few universities, show greater flexibility and color retention compared to formalin-embalmed cadavers, properties which might be considered advantageous for anatomy teaching. This study aimed to investigate student attitudes toward the dissection experience with Thiel- compared to formalin/ethanol-embalmed cadavers. It also aimed to determine if one embalming method is more advantageous in terms of learning functional anatomy through the comparison of student anterior forearm functional anatomy knowledge. Student opinions and functional anatomy knowledge were obtained through use of a questionnaire from students at two medical schools, one using Thiel-, and one using more traditional formalin/ethanol-embalmed cadavers. Both the Thiel group and the formalin group of students were surveyed shortly after completing an anterior forearm dissection session. Significant differences (P-values <0.01) in some attitudes were found toward the dissection experience between cohorts using Thiel- vs. formalin-embalmed cadavers. The Thiel group of students felt more confident about recognizing anatomy in the living individual, found it easier to identify and dissect anatomical structures, and indicated more active exploration of functional anatomy due to the retained flexibility of the cadaver. However, on testing, no significant difference in functional anatomy knowledge was found between the two cohorts. Overall, although Thiel embalming may provide an advantageous learning experience in some investigated areas, more research needs to be carried out, especially to establish whether student perception is based on reality, at least in terms of structure identification.

  1. An evaluation of outcomes following the replacement of traditional histology laboratories with self-study modules. (United States)

    Thompson, Andrew R; Lowrie, Donald J


    Changes in medical school curricula often require educators to develop teaching strategies that decrease contact hours while maintaining effective pedagogical methods. When faced with this challenge, faculty at the University of Cincinnati College of Medicine converted the majority of in-person histology laboratory sessions to self-study modules that utilize multiple audiovisual modalities and a virtual microscope platform. Outcomes related to this shift were investigated through performance on in-house examinations, results of the United States Medical Licensing Examination ® (USMLE ® ) Step 1 Examination, and student feedback. Medical School College Admissions Test ® (MCAT ® ) scores were used as a covariate when comparing in-house examinations. Results revealed no significant change in performance on in-house examinations when the content being assessed was controlled (F(2, 506) = 0.676, P = 0.51). A significant improvement in overall practical examination grade averages was associated with the self-study modules (F(6, 1164) = 10.213, P histology and cell biology portion of USMLE Step 1 Examination remained consistent throughout the time period that was investigated. Student feedback regarding the self-study modules was positive and suggested that features such as instructor narrated videos were an important component of the self-study modules because they helped recreate the experience of in-person laboratory sessions. Positive outcomes from the student perspective and no drop in examination performance suggests that utilizing self-study modules for histology laboratory content may be an option for educators faced with the challenge of reducing contact hours without eliminating content.

  2. Cadaveric dissection as an educational tool for anatomical sciences in the 21st century. (United States)

    Ghosh, Sanjib Kumar


    Anatomical education has been undergoing reforms in line with the demands of medical profession. The aim of the present study is to assess the impact of a traditional method like cadaveric dissection in teaching/learning anatomy at present times when medical schools are inclining towards student-centered, integrated, clinical application models. The article undertakes a review of literature and analyzes the observations made therein reflecting on the relevance of cadaveric dissection in anatomical education of 21st century. Despite the advent of modern technology and evolved teaching methods, dissection continues to remain a cornerstone of anatomy curriculum. Medical professionals of all levels believe that dissection enables learning anatomy with relevant clinical correlates. Moreover dissection helps to build discipline independent skills which are essential requirements of modern health care setup. It has been supplemented by other teaching/learning methods due to limited availability of cadavers in some countries. However, in the developing world due to good access to cadavers, dissection based teaching is central to anatomy education till date. Its utility is also reflected in the perception of students who are of the opinion that dissection provides them with a foundation critical to development of clinical skills. Researchers have even suggested that time has come to reinstate dissection as the core method of teaching gross anatomy to ensure safe medical practice. Nevertheless, as dissection alone cannot provide uniform learning experience hence needs to be complemented with other innovative learning methods in the future education model of anatomy.

  3. The integration of an anatomy massive open online course (MOOC) into a medical anatomy curriculum. (United States)

    Swinnerton, Bronwen J; Morris, Neil P; Hotchkiss, Stephanie; Pickering, James D


    Massive open online courses (MOOCs) are designed as stand-alone courses which can be accessed by any learner around the globe with only an internet-enabled electronic device required. Although much research has focused on the enrolment and demographics of MOOCs, their impact on undergraduate campus-based students is still unclear. This article explores the impact of integrating an anatomy MOOC in to the anatomy curriculum of a year 1 medical degree program at the University of Leeds, United Kingdom. The course did not replace any teaching that was already being delivered, and was used to supplement this teaching to support the students' consolidation and revision. Analysis of student feedback indicates a high level of usage, with evidence to suggest that female learners may have approached the course in a more personalized manner. Although the video based resources and quizzes were greatly appreciated as learning tools, significant evidence suggests the students did not engage, or were inclined to engage, with the discussion fora. Furthermore, a significant majority of students did not want the MOOC to replace the existing teaching they received. Given the feedback provided, this research suggests that although the student population believe there to be value in having access to MOOC material, their role as replacements to campus-based teaching is not supported. Details regarding the enrolment and engagement of the general public with the MOOC during the two runs are also documented, with the suggestion that graduates employed in the healthcare sector were the primary users of the course.

  4. Evaluating a technology supported interactive response system during the laboratory section of a histology course. (United States)

    Rinaldi, Vera D; Lorr, Nancy A; Williams, Kimberly


    Monitoring of student learning through systematic formative assessment is important for adjusting pedagogical strategies. However, traditional formative assessments, such as quizzes and written assignments, may not be sufficiently timely for making adjustments to a learning process. Technology supported formative assessment tools assess student knowledge, allow for immediate feedback, facilitate classroom dialogues, and have the potential to modify student learning strategies. As an attempt to integrate technology supported formative assessment in the laboratory section of an upper-level histology course, the interactive application Learning Catalytics TM , a cloud-based assessment system, was used. This study conducted during the 2015 Histology courses at Cornell University concluded that this application is helpful for identifying student misconceptions "on-the-go," engaging otherwise marginalized students, and forming a new communication venue between students and instructors. There was no overall difference between grades from topics that used the application and grades from those that did not, and students reported that it only slightly helped improve their understanding of the topic (3.8 ± 0.99 on a five-point Likert scale). However, they highly recommended using it (4.2 ± 0.71). The major limitation was regarding the image display and graphical resolution of this application. Even though students embrace the use of technology, 39% reported benefits of having the traditional light microscope available. This cohort of students led instructors to conclude that the newest tools are not always better, but rather can complement traditional instruction methods.

  5. A practical hybrid model of application, integration, and competencies at interactive table conferences in histology (ITCH). (United States)

    Ettarh, Rajunor


    Significant changes have been implemented in the way undergraduate medical education is structured. One of the challenges for component courses such as histology in medical and dental curricula is to restructure and deliver training within new frameworks. This article describes the process of aligning the purpose and experience in histology laboratory to the goal of applying knowledge gained to team-based medical practice at Tulane University School of Medicine. Between 2011 and 2015, 711 medical students took either a traditional laboratory-based histology course (353 students) or a team-based hybrid histology course with active learning in laboratory (358 students). The key difference was in the laboratory component of the hybrid course - interactive table conferences in histology-during which students developed new competencies by working in teams, reviewing images, solving problems by applying histology concepts, and sharing learning. Content, faculty and online resources for microscopy were the same in both courses. More student-student and student-faculty interactions were evident during the hybrid course but student evaluation ratings and grades showed reductions following introduction of table conferences when compared to previous ratings. However, outcomes at National Board of Medical Examiners(®) (NBME(®) ) Subject Examination in Histology and Cell Biology showed significant improvement (72.4 ± 9.04 and 76.44 ± 9.36 for percent correct answers, traditional and hybrid courses, respectively, P conferences to augment the traditional histology laboratory experience exemplifies the extent that restructuring enhancements can be used in currently taught courses in the undergraduate medical curriculum.

  6. Application of flipped classroom pedagogy to the human gross anatomy laboratory: Student preferences and learning outcomes. (United States)

    Fleagle, Timothy R; Borcherding, Nicholas C; Harris, Jennie; Hoffmann, Darren S


    To improve student preparedness for anatomy laboratory dissection, the dental gross anatomy laboratory was transformed using flipped classroom pedagogy. Instead of spending class time explaining the procedures and anatomical structures for each laboratory, students were provided online materials to prepare for laboratory on their own. Eliminating in-class preparation provided the opportunity to end each period with integrative group activities that connected laboratory and lecture material and explored clinical correlations. Materials provided for prelaboratory preparation included: custom-made, three-dimensional (3D) anatomy videos, abbreviated dissection instructions, key atlas figures, and dissection videos. Data from three years of the course (n = 241 students) allowed for analysis of students' preferences for these materials and detailed tracking of usage of 3D anatomy videos. Students reported spending an average of 27:22 (±17:56) minutes preparing for laboratory, similar to the 30 minutes previously allocated for in-class dissection preparation. The 3D anatomy videos and key atlas figures were rated the most helpful resources. Scores on laboratory examinations were compared for the three years before the curriculum change (2011-2013; n = 242) and three years after (2014-2016; n = 241). There was no change in average grades on the first and second laboratory examinations. However, on the final semi-cumulative laboratory examination, scores were significantly higher in the post-flip classes (P = 0.04). These results demonstrate an effective model for applying flipped classroom pedagogy to the gross anatomy laboratory and illustrate a meaningful role for 3D anatomy visualizations in a dissection-based course.

  7. Take away body parts! An investigation into the use of 3D-printed anatomical models in undergraduate anatomy education. (United States)

    Smith, Claire F; Tollemache, Nicholas; Covill, Derek; Johnston, Malcolm


    Understanding the three-dimensional (3D) nature of the human form is imperative for effective medical practice and the emergence of 3D printing creates numerous opportunities to enhance aspects of medical and healthcare training. A recently deceased, un-embalmed donor was scanned through high-resolution computed tomography. The scan data underwent segmentation and post-processing and a range of 3D-printed anatomical models were produced. A four-stage mixed-methods study was conducted to evaluate the educational value of the models in a medical program. (1) A quantitative pre/post-test to assess change in learner knowledge following 3D-printed model usage in a small group tutorial; (2) student focus group (3) a qualitative student questionnaire regarding personal student model usage (4) teaching faculty evaluation. The use of 3D-printed models in small-group anatomy teaching session resulted in a significant increase in knowledge (P = 0.0001) when compared to didactic 2D-image based teaching methods. Student focus groups yielded six key themes regarding the use of 3D-printed anatomical models: model properties, teaching integration, resource integration, assessment, clinical imaging, and pathology and anatomical variation. Questionnaires detailed how students used the models in the home environment and integrated them with anatomical learning resources such as textbooks and anatomy lectures. In conclusion, 3D-printed anatomical models can be successfully produced from the CT data set of a recently deceased donor. These models can be used in anatomy education as a teaching tool in their own right, as well as a method for augmenting the curriculum and complementing established learning modalities, such as dissection-based teaching.

  8. Attitudes of Australian chiropractic students toward whole body donation: a cross-sectional study. (United States)

    Alexander, Michelle; Marten, Mathew; Stewart, Ella; Serafin, Stanley; Štrkalj, Goran


    Cadavers play an important role in anatomy education. In Australia, bodies for anatomy education are acquired only through donations. To gain insight into educational dynamics in an anatomy laboratory as well as to facilitate body donation programs and thanksgiving ceremonies, it is important to understand students' attitudes toward body donation. In this cross-sectional study, the attitudes of Macquarie University's first, second, and fifth year chiropractic students toward body donation were investigated. Macquarie University chiropractic students have a four semester long anatomy program, which includes cadaver-based instruction on prosected specimens. A questionnaire was used to record respondents' demographics and attitudes toward body donation: personal, by a relative, and by a stranger. It was found that ethnicity and religion affect attitudes toward body donation, with Australian students being more willing to donate a stranger's body and atheists and agnostics being more willing to donate in general. Furthermore, willingness to donate one's own or a family member's body decreases as year of study increases, suggesting a possible negative impact of exposure to cadavers in the anatomy laboratory. This was only true, however, after controlling for age. Thus, the impact of viewing and handling prosected specimens, which is the norm in anatomy classes in Australia, may not be as strong as dissecting cadavers. It is suggested that anatomists and educators prepare students for cadaver-based instruction as well as exhibit sensitivity to cultural differences in how students approach working with cadavers, when informing different communities about body donation programs and in devising thanksgiving ceremonies. © 2013 American Association of Anatomists.

  9. Does Confucianism allow for body donation? (United States)

    Jones, D Gareth; Nie, Jing-Bao


    Confucianism has been widely perceived as a major moral and cultural obstacle to the donation of bodies for anatomical purposes. The rationale for this is the Confucian stress on xiao (filial piety), whereby individuals' bodies are to be intact at death. In the view of many, the result is a prohibition on the donation of bodies to anatomy departments for the purpose of dissection. The role of dissection throughout the development of anatomy within a Confucian context is traced, and in contemporary China the establishment of donation programs and the appearance of memorial monuments is noted. In reassessing Confucian attitudes, the stress laid on a particular interpretation of filial piety is questioned, and an attempt is made to balance this with the Confucian emphasis on a moral duty to those outside one's immediate family. The authors argue that the fundamental Confucian norm ren (humaneness or benevolence) allows for body donation as people have a moral duty to help others. Moreover, the other central Confucian value, li (rites), offers important insights on how body donation should be performed as a communal activity, particularly the necessity of developing ethically and culturally appropriate rituals for body donation. In seeking to learn from this from a Western perspective, it is contended that in all societies the voluntary donation of bodies is a deeply human activity that is to reflect the characteristics of the community within which it takes place. This is in large part because it has educational and personal repercussions for students. Anat Sci Educ. © 2018 American Association of Anatomists. © 2018 American Association of Anatomists.

  10. Improving near-peer teaching quality in anatomy by educating teaching assistants: An example from Sweden. (United States)

    Johansson, Ellen; Holmin, Tobias E; Johansson, Bengt R; Braide, Magnus


    Peer-assisted learning has gained momentum in a variety of disciplines, including medical education. In Gothenburg, Sweden, medical students who have finished their compulsory anatomy courses have the option of working as teaching assistants (TAs). Teaching assistants provide small group teaching sessions as a complement to lectures given by faculty. Previously, TAs were left to handle the role as junior teachers by themselves, but since 2011, a continuation course in anatomy has been developed with the aim of providing the TAs better anatomy knowledge and guidance for teaching. The course was designed to comprise 7.5 ECTS credits (equivalent to 5 weeks of full-time studies), and today all TAs are required to take this course before undertaking their own teaching responsibilities. This study aims to compare course evaluations of TA teaching before and after the introduction of the anatomy continuation course, in order to understand how students perceived teaching performed by self-learned versus trained TAs. The results of this study demonstrate that there was a trend towards better teaching performed by trained TAs. The variability in rankings decreased significantly after the introduction of the continuation course. This was mainly due to an improvement among the TAs with the lowest levels of performance. In addition to comparing student rankings, TAs were interviewed regarding their experiences and perceptions within the continuation course. The course was generally positively regarded. The TAs described a sense of cohesion and appreciation since the institute invested in a course dedicated specifically for them.

  11. The skeletons in our closet: E-learning tools and what happens when one side does not fit all. (United States)

    Van Nuland, Sonya E; Rogers, Kem A


    In the anatomical sciences, e-learning tools have become a critical component of teaching anatomy when physical space and cadaveric resources are limited. However, studies that use empirical evidence to compare their efficacy to visual-kinesthetic learning modalities are scarce. The study examined how a visual-kinesthetic experience, involving a physical skeleton, impacts learning when compared with virtual manipulation of a simple two-dimensional (2D) e-learning tool, A.D.A.M. Interactive Anatomy. Students from The University of Western Ontario, Canada (n = 77) participated in a dual-task study to: (1) investigate if a dual-task paradigm is an effective tool for measuring cognitive load across these different learning modalities; and (2) to assess the impact of knowledge recall and spatial ability when using them. Students were assessed using knowledge scores, Stroop task reaction times, and mental rotation test scores. Results demonstrated that the dual-task paradigm was not an effective tool for measuring cognitive load across different learning modalities with respect to kinesthetic learning. However, our study highlighted that handing physical specimens yielded major, positive impacts on performance that a simple commercial e-learning tool failed to deliver (P < 0.001). Furthermore, students with low spatial ability were significantly disadvantaged when they studied the bony joint and were tested on contralateral images (P = 0.046, R = 0.326). This suggests that, despite limbs being mirror images, students should be taught the anatomy of, as well as procedures on, both sides of the human body, enhancing the ability of all students, regardless of spatial ability, to take anatomical knowledge into the clinic and perform successfully.

  12. Using collaborative two-stage examinations to address test anxiety in a large enrollment gateway course. (United States)

    Fournier, Kimberly A; Couret, Jannelle; Ramsay, Jason B; Caulkins, Joshua L


    Large enrollment foundational courses are perceived as "high stakes" because of their potential to act as barriers for progression to the next course or admittance to a program. The nature of gateway courses makes them ideal settings to explore the relationship between anxiety, pedagogical interventions, and student performance. Here, two-stage collaborative examinations were implemented to improve test-taking skills and address widespread test anxiety in an introductory human anatomy course. Test anxiety data were collected (using the Motivated Strategies for Learning Questionnaire) before the first examination and last examination. Most students experienced decreased test anxiety over the course of the semester; however, some students may have experienced performance limiting conditions due to test anxiety at the end of the semester based on academic ability in the course (in "C" students when compared to "A" students: P < 0.00006 and "B" students: P < 0.05), overall academic ability (in academically weaker students: P < 0.025), and demographic factors (in women: P < 0.025). The strongest performances on examinations were primarily observed in already academically strong students (mean individual performance: P < 0.000, mean group performance: P < 0.000). Furthermore, changes in test anxiety were not significantly associated with the group portion of the examinations. Patterns of changes in test anxiety over the course of the semester underscore a complex interaction between test anxiety, student background, and student performance. Results suggest that pathways for test anxiety in "high stakes" courses may be separate from the mechanisms responsible for the benefits of collaborative testing.

  13. Optimizing the use of cadavers by integrating pathology during anatomy dissection. (United States)

    Geldenhuys, Elsje-Márie; Burger, Elsie Helena; van Helden, Paul David; Mole, Calvin Gerald; Kotzé, Sanet Henriët


    An accurate knowledge of anatomy, especially natural variation within individuals, is of vital clinical importance. Cadaver dissection during anatomical training may be a valuable introduction to pathology for undergraduate students, which can contribute greatly to a successful medical career. The purpose of this study was to determine the extent and type of pathology lesions in a cadaver population (n = 127) used for medical dissection. This was done to gauge whether sufficient pathology lesions representative of all the organ systems were present in the cadaver population to warrant the use of cadavers as an additional pathology learning resource. This study demonstrated a wide variety of pathology lesions in different organ systems. The respiratory system was most affected with pulmonary tuberculosis (TB) lesions being the most common finding (seen in 76% of cadavers) followed by bronchopneumonia and emphysema. Other common pathology findings included atherosclerosis, colonic diverticula, and chronic pyelonephritis. Skeletal fractures and degenerative joint disease were also noted. This study shows that cadaveric dissection offers a chance to alert and expose students to a wide variety of gross pathology and histopathology. It has been suggested that most medical students will practice in primary health care and as such more attention should be given to the pathology of commonly encountered diseases. This is particularly true for developing countries, where diseases such as TB are commonly encountered. The integration of pathology into the dissection hall may therefore be beneficial to student learning while simultaneously optimizing the use of cadaver material.

  14. Influence of study approaches and course design on academic success in the undergraduate anatomy laboratory. (United States)

    Eleazer, Courtney D; Scopa Kelso, Rebecca


    Many pre-health professional programs require completion of an undergraduate anatomy course with a laboratory component, yet grades in these courses are often low. Many students perceive anatomy as a more challenging subject than other coursework, and the resulting anxiety surrounding this perception may be a significant contributor to poor performance. Well-planned and deliberate guidance from instructors, as well as thoughtful course design, may be necessary to assist students in finding the best approach to studying for anatomy. This article assesses which study habits are associated with course success and whether course design influences study habits. Surveys (n = 1,274) were administered to students enrolled in three undergraduate human anatomy laboratory courses with varying levels of cooperative learning and structured guidance. The surveys collected information on potential predictors of performance, including student demographics, educational background, self-assessment ability, and study methods (e.g., flashcards, textbooks, diagrams). Compared to low performers, high performers perceive studying in laboratory, asking the instructor questions, quizzing alone, and quizzing others as more effective for learning. Additionally, students co-enrolled in a flipped, active lecture anatomy course achieve higher grades and find active learning activities (e.g., quizzing alone and in groups) more helpful for their learning in the laboratory. These results strengthen previous research suggesting that student performance is more greatly enhanced by an active classroom environment that practices successful study strategies rather than one that simply encourages students to employ such strategies inside and outside the classroom.

  15. Mixed methods student evaluation of an online systemic human anatomy course with laboratory. (United States)

    Attardi, Stefanie M; Choi, Suwhan; Barnett, John; Rogers, Kem A


    A fully online section of an existing face-to-face (F2F) systemic human anatomy course with a prosection laboratory was offered for the first time in 2012-2013. Lectures for F2F students (N = 365) were broadcast in both live and archived format to online students (N = 40) using virtual classroom software. Laboratories were delivered online by a teaching assistant who manipulated 3D computer models in the virtual classroom environment. An exploratory sequential mixed methods approach was undertaken to determine the most important deciding factors that drive students' preferences for a given format and then to generate theory on the strengths and weaknesses of the online format. Students (20 online; 310 F2F) volunteered to participate in a crossover period of one week to expose them to the course section in which they were not originally registered. Open ended interviews (20 online; 20 F2F) and quantitative surveys (270 F2F) were conducted following a crossover. Students valued pace control, schedule, and location flexibility of learning from archived materials and being assessed online. In the online laboratory they had difficulty using the 3D models and preferred the unique and hands-on experiences of cadaveric specimens. The F2F environment was conducive to learning in both lecture and laboratory because students felt more engaged by instructors in person and were less distracted by their surroundings. These results suggest the need to improve the online experience by increasing the quality of student-instructor communication and in turn student-content interaction with the 3D models.

  16. Dissecting the voice: Health professions students' perceptions of instructor age and gender in an online environment and the impact on evaluations for faculty. (United States)

    Doubleday, Alison F; Lee, Lisa M J


    Gender and age bias is well-documented in academia with many studies demonstrating bias in students' evaluations of instructors. Failure of an instructor to meet gender or age-based expectations can translate to lower scores or negative comments on evaluations. While there is some evidence of bias in students' evaluations of online instructors, current studies have not fully examined the relationship between bias and instructor vocal characteristics. First-year dental students at two institutions were randomly assigned one of four videos on spinal cord anatomy to view. Videos contained identical content but were narrated by individuals of different gender and age (younger man, younger woman, older man, older woman). Students completed a content-based prequiz, watched the video, completed a postquiz, and answered a questionnaire evaluating the video and instructor. Students at Institution A rated the younger man and younger woman highest for nearly every evaluation category. At Institution B students rated the older man and younger woman highest. Results reveal that the older woman's voice received the lowest rankings for nearly every question in both samples. This report confirms the presence of gender and age bias in student evaluations of instructors in an online environment and demonstrates that bias may surface in response to vocal characteristics. Bias may impact older women more significantly than other groups. Differences in results from Institution A and Institution B suggest that factors affecting student perceptions of instructors, and the roles that gender and age bias may play in student evaluations, are complex and may be contextual.

  17. Improving Online Interactions: Lessons from an Online Anatomy Course with a Laboratory for Undergraduate Students. (United States)

    Attardi, Stefanie M; Barbeau, Michele L; Rogers, Kem A


    An online section of a face-to-face (F2F) undergraduate (bachelor's level) anatomy course with a prosection laboratory was offered in 2013-2014. Lectures for F2F students (353) were broadcast to online students (138) using Blackboard Collaborate (BBC) virtual classroom. Online laboratories were offered using BBC and three-dimensional (3D) anatomical computer models. This iteration of the course was modified from the previous year to improve online student-teacher and student-student interactions. Students were divided into laboratory groups that rotated through virtual breakout rooms, giving them the opportunity to interact with three instructors. The objectives were to assess student performance outcomes, perceptions of student-teacher and student-student interactions, methods of peer interaction, and helpfulness of the 3D computer models. Final grades were statistically identical between the online and F2F groups. There were strong, positive correlations between incoming grade average and final anatomy grade in both groups, suggesting prior academic performance, and not delivery format, predicts anatomy grades. Quantitative student perception surveys (273 F2F; 101 online) revealed that both groups agreed they were engaged by teachers, could interact socially with teachers and peers, and ask them questions in both the lecture and laboratory sessions, though agreement was significantly greater for the F2F students in most comparisons. The most common methods of peer communication were texting, Facebook, and meeting F2F. The perceived helpfulness of the 3D computer models improved from the previous year. While virtual breakout rooms can be used to adequately replace traditional prosection laboratories and improve interactions, they are not equivalent to F2F laboratories.

  18. Development of a didactical training concept for peer tutors in gross anatomy. (United States)

    Alvarez, Simone; Nikendei, Christoph; Schultz, Jobst-Hendrik


    Even though peer tutors are often used in gross anatomy courses, research in the field is rather a subject of the last two decades. This is especially true about the didactical challenges these types of peer tutors experience during their tutorials and about how they are prepared for the task. The aim of the presented study was to learn about the training needs of the tutors, and to subsequently design, implement, and evaluate a didactical training concept. A qualitative design was chosen to examine how tutors can best be prepared for tutorials of gross anatomy. To do so, focus group interviews were conducted. The data were analyzed and grouped into various concepts, using semi-structured interview questions as guidance. It was found that peer tutors are in need of training in the following aspects: Dealing with students who are experiencing difficulties during or as a result of dissection, dealing with group dynamics, that is, at the dissection table, keeping students motivated, time management, and staying confident as a tutor. In order to be regarded as useful and relevant in the eyes of tutors, a preparatory training course should include all these aspects in addition to general didactical training elements. Training needs of peer tutors of gross anatomy go beyond the content of standardized didactical curricula; therefore, tutors should be prepared with a curriculum that is specifically geared toward the many challenges associated with teaching gross anatomy to first year medical students which are already so well documented in the research literature.

    Cadaver dissection stands as a crucial component in medical curricula around the world, although computer-based multimedia programs have been introduced in order to replace the need for cadaver donations. Due to a decrease in the number of unclaimed bodies and rather few donations, there is an insufficient number of cadavers for anatomical studies in Iran. This study was carried out to evaluate medical students' awareness and willingness regarding body donation in Kashan University of Medical Sciences, Iran. In this study, a questionnaire was designed to focus on the cultural acceptability and personal willingness to donate one's body after death. Students from the university's anatomy classes (n = 331) participated in this study. Seventy-seven percent of the students expressed their agreement toward the idea of utilizing body donation services, though only 25.4% of participants were willing to donate their own bodies. None of the demographic factors were associated with cultural acceptability or personal willingness towards body donation. These findings indicated that besides "payment", other factors were associated with students' willingness to become donors. All factors of awareness except "previous awareness of organization" were associated with cultural acceptability. In this study, students suggested that encouraging people to register for body donation using mass media (25.6%) and teaching students to respect cadavers in the dissection environment (24.8%) were the best solutions for addressing the lack of cadavers. These findings indicated that a lack of awareness about body donation might be the main factor responsible for unwillingness towards body donation; therefore, improving the public's awareness and addressing the willingness of students regarding body donation may help overcome the current lack of donated cadavers.

  20. Implementation and modification of an anatomy-based integrated curriculum. (United States)

    Klement, Brenda J; Paulsen, Douglas F; Wineski, Lawrence E


    Morehouse School of Medicine elected to restructure its first-year medical curriculum by transitioning from a discipline-based to an integrated program. The anatomy course, with regional dissection at its core, served as the backbone for this integration by weaving the content from prior traditional courses into the curriculum around the anatomy topics. There were four primary goals for this restructuring process. Goal 1: develop new integrated courses. Course boundaries were established at locations where logical breaks in anatomy content occurred. Four new courses were created, each containing integrated subject content. Goal 2: establish a curriculum management team. The team consisted of course directors, subject specialists, and a curriculum director. This team worked together to efficiently manage the new curriculum. Goal 3: launch contemporary examination and question banking methods. An electronic system, in which images could be included, was implemented for examinations and quizzes, and for storing and refining questions. Goal 4: ensure equitable distribution of standardized examinations and course grading systems among all courses. Assessments included quizzes, in-course examinations, and National Board of Medical Examiners ® (NBME ® ) Subject Examinations. A standard plan assigned the contribution of each to the final course grade. Significant improvement was seen on subject examinations. Once the obstacles and challenges of integration were overcome, a robust and efficient education program was developed. The curriculum is expected to continue evolving and improving, while retaining full regional dissection as a core element.

  1. Human preservation techniques in anatomy: A 21st century medical education perspective. (United States)

    Balta, Joy Y; Cronin, Michael; Cryan, John F; O'Mahony, Siobhain M


    Anatomy is the cornerstone of education for healthcare professionals with the use of human material providing an excellent teaching tool in the modern curricula. The ability and quality of preservation of human remains has enabled such use. The introduction of formaldehyde as a preservative in 1893 was an important step in the history of preservation. With the European Union directive on the use of formaldehyde and its expected banning, anatomists are trying to find a more convenient and safe substitute. In this review, we compare the different techniques used based on the need for embalming, fixative used, period of preservation and the features of the embalmed specimen. The fact that embalming is used in different disciplines, multiple purposes and described in different languages has led to the development of ambiguous interchangeable terminology. Overall, there is a lack of information specifically classifying, listing and comparing different embalming techniques, and this may be due to the fact that no internationally recognized experimental standards are adhered to in this field. Anatomists strive to find an embalming technique that allows the preserved specimen to accurately resemble the living tissue, preserve the body for a long period of time and reduces health risk concerns related to working with cadavers. There is a need for embalming to shift to an independent modern day science with well-founded research at the heart of it. While this may take time and agreement across nations, we feel that this review adds to the literature to provide a variety of different methods that can be employed for human tissue preservation depending on the desired outcome. © 2015 Wiley Periodicals, Inc.

  2. Measuring learning gain: Comparing anatomy drawing screencasts and paper-based resources. (United States)

    Pickering, James D


    The use of technology-enhanced learning (TEL) resources is now a common tool across a variety of healthcare programs. Despite this popular approach to curriculum delivery there remains a paucity in empirical evidence that quantifies the change in learning gain. The aim of the study was to measure the changes in learning gain observed with anatomy drawing screencasts in comparison to a traditional paper-based resource. Learning gain is a widely used term to describe the tangible changes in learning outcomes that have been achieved after a specific intervention. In regard to this study, a cohort of Year 2 medical students voluntarily participated and were randomly assigned to either a screencast or textbook group to compare changes in learning gain across resource type. Using a pre-test/post-test protocol, and a range of statistical analyses, the learning gain was calculated at three test points: immediate post-test, 1-week post-test and 4-week post-test. Results at all test points revealed a significant increase in learning gain and large effect sizes for the screencast group compared to the textbook group. Possible reasons behind the difference in learning gain are explored by comparing the instructional design of both resources. Strengths and weaknesses of the study design are also considered. This work adds to the growing area of research that supports the effective design of TEL resources which are complimentary to the cognitive theory of multimedia learning to achieve both an effective and efficient learning resource for anatomical education.

  3. Social media and anatomy education: Using twitter to enhance the student learning experience in anatomy. (United States)

    Hennessy, Catherine M; Kirkpatrick, Emma; Smith, Claire F; Border, Scott


    Neuroanatomy is a difficult subject in medical education, with students often feeling worried and anxious before they have even started, potentially decreasing their engagement with the subject. At the University of Southampton, we incorporated the use of Twitter as a way of supporting students' learning on a neuroanatomy module to evaluate how it impacted upon their engagement and learning experience. The #nlm2soton hashtag was created and displayed (via a widget) on the university's virtual learning environment (VLE) for a cohort of 197 Year 2 medical students studying neuroanatomy. Student usage was tracked to measure levels of engagement throughout the course and frequency of hashtag use was compared to examination results. Student opinions on the use of Twitter were obtained during a focus group with eleven students and from qualitative questionnaires. The hashtag was used by 91% of the student cohort and, within this, more students chose to simply view the hashtag rather than make contributions. The completed questionnaire responses (n = 150) as well as focus group outcomes revealed the value of using Twitter. A negligible correlation was found between student examination scores and their viewing frequency of the hashtag however, no correlation was found between examination scores and contribution frequency. Despite this, Twitter facilitated communication, relieved anxieties and raised morale, which was valued highly by students and aided engagement with neuroanatomy. Twitter was successful in creating and providing a support network for students during a difficult module.

  4. How useful is YouTube in learning heart anatomy? (United States)

    Raikos, Athanasios; Waidyasekara, Pasan


    Nowadays more and more modern medical degree programs focus on self-directed and problem-based learning. That requires students to search for high quality and easy to retrieve online resources. YouTube is an emerging platform for learning human anatomy due to easy access and being a free service. The purpose of this study is to make a quantitative and qualitative analysis of the available human heart anatomy videos on YouTube. Using the search engine of the platform we searched for relevant videos using various keywords. Videos with irrelevant content, animal tissue, non-English language, no sound, duplicates, and physiology focused were excluded from further elaboration. The initial search retrieved 55,525 videos, whereas only 294 qualified for further analysis. A unique scoring system was used to assess the anatomical quality and details, general quality, and the general data for each video. Our results indicate that the human heart anatomy videos available on YouTube conveyed our anatomical criteria poorly, whereas the general quality scoring found borderline. Students should be selective when looking up on public video databases as it can prove challenging, time consuming, and the anatomical information may be misleading due to absence of content review. Anatomists and institutions are encouraged to prepare and endorse good quality material and make them available online for the students. The scoring rubric used in the study comprises a valuable tool to faculty members for quality evaluation of heart anatomy videos available on social media platforms.

  5. What type of learner are your students? Preferred learning styles of undergraduate gross anatomy students according to the index of learning styles questionnaire. (United States)

    Quinn, Melissa M; Smith, Theodore; Kalmar, Eileen L; Burgoon, Jennifer M


    Students learn and process information in many different ways. Learning styles are useful as they allow instructors to learn more about students, as well as aid in the development and application of useful teaching approaches and techniques. At the undergraduate level there is a noticeable lack of research on learning style preferences of students enrolled in gross anatomy courses. The Index of Learning Styles (ILS) questionnaire was administered to students enrolled in a large enrollment undergraduate gross anatomy course with laboratory to determine their preferred learning styles. The predominant preferred learning styles of the students (n = 505) enrolled in the gross anatomy course were active (54.9%), sensing (85.1%), visual (81.2%), and sequential (74.4%). Preferred learning styles profiles of particular majors enrolled in the course were also constructed; analyses showed minor variation in the active/reflective dimension. An understanding of students' preferred learning styles can guide course design but it should not be implemented in isolation. It can be strengthened (or weakened) by concurrent use of other tools (e.g., flipped classroom course design). Based on the preferred learning styles of the majority of undergraduate students in this particular gross anatomy course, course activities can be hands on (i.e., active), grounded in concrete information (i.e., sensing), utilize visual representation such as images, figures, models, etc. (i.e., visual), and move in small incremental steps that build on each topic (i.e., sequential).

  6. Another nail in the coffin for learning styles? Disparities among undergraduate anatomy students' study strategies, class performance, and reported VARK learning styles. (United States)

    Husmann, Polly R; O'Loughlin, Valerie Dean


    The concept and existence of learning styles has been fraught with controversy, and recent studies have thrown their existence into doubt. Yet, many students still hold to the conventional wisdom that learning styles are legitimate, and may adapt their outside of class study strategies to match these learning styles. Thus, this study aims to assess if undergraduate anatomy students are more likely to utilize study strategies that align with their hypothetical learning styles (using the VARK analysis from Fleming and Mills, , Improve Acad. 11:137-155) and, if so, does this alignment correlate with their outcome in an anatomy course. Relatedly, this study examines whether students' VARK learning styles are correlated with course outcomes regardless of the students' study strategies, and whether any study strategies are correlated with course outcomes, regardless of student-specific VARK results. A total of 426 anatomy students from the 2015 and 2016 Fall semesters completed a study strategies survey and an online VARK questionnaire. Results demonstrated that most students did not report study strategies that correlated with their VARK assessment, and that student performance in anatomy was not correlated with their score in any VARK categories. Rather, some specific study strategies (irrespective of VARK results), such as use of the virtual microscope, were found to be positively correlated with final class grade. However, the alignment of these study strategies with VARK results had no correlation with anatomy course outcomes. Thus, this research provides further evidence that the conventional wisdom about learning styles should be rejected by educators and students alike.

  7. Distributed retrieval practice promotes superior recall of anatomy information. (United States)

    Dobson, John L; Perez, Jose; Linderholm, Tracy


    Effortful retrieval produces greater long-term recall of information when compared to studying (i.e., reading), as do learning sessions that are distributed (i.e., spaced apart) when compared to those that are massed together. Although the retrieval and distributed practice effects are well-established in the cognitive science literature, no studies have examined their additive effect with regard to learning anatomy information. The aim of this study was to determine how the benefits of retrieval practice vary with massed versus distributed learning. Participants used the following strategies to learn sets of skeletal muscle anatomy: (1) studying on three different days over a seven day period (SSSS 7,2,0 ), (2) studying and retrieving on three different days over a seven day period (SRSR 7,2,0 ), (3) studying on two different days over a two day period (SSSSSS 2,0 ), (4) studying and retrieving on two separate days over a two day period (SRSRSR 2,0 ), and (5) studying and retrieving on one day (SRx6 0 ). All strategies consisted of 12 learning phases and lasted exactly 24 minutes. Muscle information retention was assessed via free recall and using repeated measures ANOVAs. A week after learning, the recall scores were 24.72 ± 3.12, 33.88 ± 3.48, 15.51 ± 2.48, 20.72 ± 2.94, and 12.86 ± 2.05 for the SSSS 7,2,0 , SRSR 7,2,0 , SSSSSS 2,0 , STSTST 2,0 , and SRx6 0 strategies, respectively. In conclusion, the distributed strategies produced significantly better recall than the massed strategies, the retrieval-based strategies produced significantly better recall than the studying strategies, and the combination of distributed and retrieval practice generated the greatest recall of anatomy information.

  8. [The neuroanatomy of Juan Valverde de Amusco and medicine at the time of the Spanish renaissance]. (United States)

    Martín Araguz, A; Bustamante Martínez, C; Toledo León, D; López Gómez, M; Moreno Martínez, J M

    Juan Valverde de Amusco (c. 1525-c. 1564) is considered to have been the most important Spanish anatomist of the XVI century. A follower of Vesalius, he increased and divulged knowledge of anatomy during the Renaissance and his book The history of the composition of the human body was printed in Rome in 1556. The objective of this paper is to study the neuroanatomy in this book and present unpublished biographical data and describe the main contributions of this Castilian doctor to the neurosciences, in the context of Spanish medicine during the Renaissance period. He was born in the town of Hamusco (today Amusco) in the province of Palencia, which belonged to the Crown of Castile. Juan Valverde emigrated to Italy to improve his scientific knowledge. He carried out anatomical studies using the then revolutionary method of direct observation, as opposed to the Galenic criteria of authority inherited from the Medieval period. He trained in Padua under Realdo Colombo and lived in Rome where he practiced medicine until his death, becoming deservedly famous. He did not return to Spain since in the Spanish universities of the time there was a mentality which was reactionary to modern anatomy. His works, published in Italy but in the Spanish language, give an idea of the power of the Crown of Castile in the Europe of that period. The book is profusely illustrated with the first illustrations ever published in the history of printing, drawn by Nicolas Beatrizet. The book was sold widely and was translated and reedited on many occasions, until well into the XVIII century. For the first time Valverde made precise references to the minor circulation. He was the first anatomist to describe the muscles for movement of the eye correctly and the intracranial course of the carotid arteries. In his work he made the first drawing of the stapes, described by the Valencian Luis Collado. Vesalius and Valverde contributed decisively to the beginnings of modern neuroanatomy. Thanks to

  9. Exploring relationships between personality and anatomy performance. (United States)

    Finn, Gabrielle M; Walker, Simon J; Carter, Madeline; Cox, David R; Hewitson, Ruth; Smith, Claire F


    There is increasing recognition in medicine of the importance of noncognitive factors, including personality, for performance, and for good medical practice. The personality domain of conscientiousness is a well-established predictor of performance in workplace and academic settings. This study investigates the relationships between the "Big Five" personality domains, the facets of conscientiousness and performance in a practical anatomy examination. First- and second-year undergraduate medical students (n = 85) completed a paper-based questionnaire, which included a 50-item measure of the Big Five personality domains (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) and a 60-item measure of the six conscientiousness facets (orderliness, dutifulness, achievement-striving, self-discipline, self-efficacy, and cautiousness) from the International Personality Item Pool (IPIP). In addition, routinely-collected academic performance scores from the end of semester anatomy practical examinations (spotters) were obtained. Anatomy examination performance correlated moderately with conscientiousness (r = 0.24, P = 0.03). Of the six facets of conscientiousness, a positive relationship was observed between anatomy examination performance and achievement striving (r = 0.22, P = 0.05). In conclusion, this study found that performance in an anatomy examination was related to higher levels of conscientiousness and, more specifically, to higher levels of achievement striving. The results have implications for selection and assessment in medicine. © 2015 American Association of Anatomists.

  10. [An anatomical wax of the deep structures of the pelvic limb (by Tramond, 19th century): observation of the tridimensional photographic rotation]. (United States)

    Cazenoves, A; Le Floch-Prigent, P


    Anatomical wax modelling was widely used during the 19(th) century, especially in France and Italy. In Paris, The Tramond house was specialized in the realization of this kind of samples. The sample was placed on two large horizontal marble disks, rotating every 5°. We could then describe the sample, verify its anatomical accuracy and also perform a virtual reconstruction with Quick Time Reality QTVR(®) software. The muscular, nervous and arterial elements were represented. We divided the description in three parts: (1) lumbar, pelvic and femoral; (2) femoro-tibial; and (3) tibio-tarsian. We focused the anatomical description on the sciatic nerve; on the organization of the muscles of the gluteal region and the neurovascular organization; and on arterial segmentation. This sample was getting damaged with time, noticeably the representation of the nerves, which are very thin and so, very fragile. Nowadays, 3D representation of the dissected human body is more common, with new techniques such as plastination (Von Hagen's type), which allows one to preserve all the anatomical elements of the subject. This paper and the realization of the virtual museum also aim to participate in a work memory, which recognize the knowledge of the anatomist of wax makers, their teaching quality remained unequalled as their obvious artistical value.

  11. Design and implementation of an online systemic human anatomy course with laboratory. (United States)

    Attardi, Stefanie M; Rogers, Kem A


    Systemic Human Anatomy is a full credit, upper year undergraduate course with a (prosection) laboratory component at Western University Canada. To meet enrollment demands beyond the physical space of the laboratory facility, a fully online section was developed to run concurrently with the traditional face to face (F2F) course. Lectures given to F2F students are simultaneously broadcasted to online students using collaborative software (Blackboard Collaborate). The same collaborative software is used by a teaching assistant to deliver laboratory demonstrations in which three-dimensional (3D) virtual anatomical models are manipulated. Ten commercial software programs were reviewed to determine their suitability for demonstrating the virtual models, resulting in the selection of Netter's 3D Interactive Anatomy. Supplementary online materials for the central nervous system were developed by creating 360° images of plastinated prosected brain specimens and a website through which they could be accessed. This is the first description of a fully online undergraduate anatomy course with a live, interactive laboratory component. Preliminary data comparing the online and F2F student grades suggest that previous student academic performance, and not course delivery format, predicts performance in anatomy. Future qualitative studies will reveal student perceptions about their learning experiences in both of the course delivery formats. © 2014 American Association of Anatomists.

  12. A Rare Variation of the Human Median Nerve Direction

    Directory of Open Access Journals (Sweden)



    Full Text Available Introduction The brachial plexus, a complex network of nerves, innervates to the upper limbs. Variation in the course of the nerves in the upper limb is common. Case Presentation This paper describes two cases of upper limb variations in a cadaver dissected at Lorestan University of Medical Sciences. In the first variation, the median nerve in the arm has a different route, so that the median moves deep into the brachialis muscle. In the latter case, after piercing the coracobrachialis muscle a musculocutaneous nerve exists between the brachialis and biceps and goes to the lateral region of the forearm. This is known as the lateral cutaneous nerve of the forearm nerve, and innervates the skin of the lateral part of the forearm and the dorsal part of the hand. Conclusions Because of the possibility of damage to the brachial plexus branches is high in upper limb injuries and surgeries, full knowledge of normal anatomy and variations of these branches is essential for orthopedic specialists, neurosurgeons, radiologists, and anatomists.

  13. Anatomy and variations of palmaris longus in fetuses. (United States)

    Albay, S; Kastamoni, Yadigar; Sakalli, Büşra; Tunali, S


    The aim of this study was to assess the absence of the palmaris longus, the proportion of the lengths of tendon and muscle belly, the development of the tendon and the belly during the fetal period, look for any difference between sides and gender. Fifty-eight spontaneously aborted human fetuses (26 female, 32 male, 116 upper extremities) were studied. The presence or absence of the palmaris longus was determined. The lengths of the belly and tendon were measured, and belly/tendon length ratio was calculated. Correlation with gestational age, body side and gender were studied. The muscle was absent in 44 forearms (37.93%; 20 right side, 34.48%; 24 left side, 41.38%); being bilateral in 19 of 58 fetuses (32.76%) and unilateral in six (10.34%). The unilateral absence rate was higher on the left side with a statistically significant difference. The absence of palmaris longus was more common in females, and the difference was statistically significant. The belly/tendon length ratio was 1.04 ± 0.35 on the right side and 1.09 ± 0.3 on the left. It did not show any difference according the fetal age. A sound knowledge on the anatomy and variations of palmaris longus is of great importance during surgical interventions; because it is the first choice for tendon grafts, by the virtue of its structure and function. Thus, this study is of academic interest for anatomists and hand surgeons alike.

  14. Integration of medical imaging including ultrasound into a new clinical anatomy curriculum. (United States)

    Moscova, Michelle; Bryce, Deborah A; Sindhusake, Doungkamol; Young, Noel


    In 2008 a new clinical anatomy curriculum with integrated medical imaging component was introduced into the University of Sydney Medical Program. Medical imaging used for teaching the new curriculum included normal radiography, MRI, CT scans, and ultrasound imaging. These techniques were incorporated into teaching over the first two years of the program as a part of anatomy practical sessions, in addition to dedicated lectures and tutorials given by imaging specialists. Surveys were conducted between 2009 and 2012 to evaluate the student acceptance of the integration. Students were asked to rate individual activities as well as provide open-ended comments. The number of students who responded to the surveys varied from 40% to 98%. Over 90% of the respondents were satisfied with the overall quality of teaching in the anatomy units. In summary, 48% to 63% of the responding students thought that the specialist imaging lectures helped them learn effectively; 72% to 77% of students thought that the cross-sectional practical sessions helped them to better understand the imaging modalities of CT, MRI, and ultrasound; 76% to 80% of students considered hands-on ultrasound session to be useful in understanding the application of ultrasound in abdominal imaging. The results also revealed key similarities and differences in student perceptions of the new integrated curriculum for students with both a high and low prior exposure to anatomy. Further evaluation will aid in refining the integrated medical imaging program and providing its future direction. © 2014 American Association of Anatomists.

  15. What is an objective structured practical examination in anatomy? (United States)

    Yaqinuddin, Ahmed; Zafar, Muhammad; Ikram, Muhammad Faisal; Ganguly, Paul


    Assessing teaching-learning outcomes in anatomical knowledge is a complex task that requires the evaluation of multiple domains: theoretical, practical, and clinical knowledge. In general, theoretical knowledge is tested by a written examination system constituted by multiple choice questions (MCQs) and/or short answer questions (SAQ). The assessment of practical knowledge (three-dimensional anatomical concepts) involves oral, spot, or objective structured practical examinations (OSPE). Finally, the application of anatomical knowledge to patients is tested mainly through objective structured clinical examinations (OSCE). The major focus of this study is the OSPE. Although many schools challenge students using this tool in practical examinations in the early phase of the curriculum, the true meaning of OSPE is frequently forgotten and it becomes, in reality, a spot examination. This article, for the first time, describes how the concept of the OSPE has evolved and is currently being used to assess the practical domain of anatomical knowledge in a problem-based curriculum at Alfaisal University College of Medicine. In addition, it describes the main differences from the spot examination, which is normally used in traditional medical curricula. The authors believe that the OSPE remains the most efficient tool to assess the practical aspects of anatomical knowledge in a system where basic knowledge is integrated with the clinical or functional part of anatomy. However, this contention only holds true if the OSPE process revolves around structured objectives. Copyright © 2012 American Association of Anatomists.

  16. The development of a core syllabus for the teaching of head and neck anatomy to medical students. (United States)

    Tubbs, R Shane; Sorenson, Edward P; Sharma, Amit; Benninger, Brion; Norton, Neil; Loukas, Marios; Moxham, Bernard J


    The study of human anatomy has traditionally served as a fundamental component in the basic science education of medical students, yet there exists a remarkable lack of firm guidance on essential features that must be included in a gross anatomy course, which would constitute a "Core Syllabus" of absolutely mandatory structures and related clinical pathologies. While universal agreement on the details of a core syllabus is elusive, there is a general consensus that a core syllabus aims to identify the minimum level of knowledge expected of recently qualified medical graduates in order to carry out clinical procedures safely and effectively, while avoiding overloading students with unnecessary facts that have less immediate application to their future careers as clinicians. This paper aims to identify consensus standards of essential features of Head and Neck anatomy via a Delphi Panel consisting of anatomists and clinicians who evaluated syllabus content structures (greater than 1,000) as "essential", "important", "acceptable", or "not required." The goal is to provide guidance for program/course directors who intend to provide the optimal balance between establishing a comprehensive list of clinically relevant essential structures and an overwhelming litany, which would otherwise overburden trainees in their initial years of medical school with superficial rote learning, which potentially dilutes the key and enduring fundamental lessons that prepare students for training in any medical field.

  17. The anatomy competence score: a new marker for anatomical ability. (United States)

    Schoeman, Scarpa; Chandratilake, Madawa


    The assessment of students' ability in gross anatomy is a complex process as it involves the measurement of multiple facets. In this work, the authors developed and introduced the Anatomy Competence Score (ACS), which incorporates the three domains of anatomy teaching and assessment namely: theoretical knowledge, practical 3D application of the knowledge, and clinical or bedside application of knowledge on patients. Equal contributions from these tripartite domains were used to synthesize the ACS. The theory knowledge was assessed using MCQs and short answer questions while the knowledge of practical 3D application was assessed using an Objective Structured Practical Examination (OSPE). The clinical or bedside application of anatomy knowledge was assessed by an Objective Structured Clinical Examination (OSCE). In this correlation study, the authors examined the interdomain correlations of the summative marks for the three contributing domains of the ACS, in order to examine the rationality of this new marker. Three cohorts of medical students (n = 538) at St. George's, University of London (SGUL) Medical School in the United Kingdom were included and analyzed. The results demonstrated that the correlations between the three domains were significantly low or moderate. The three domains probably represent unique knowledge and abilities. Therefore, it would appear that the average of the domains scores (the ACS) provide a comprehensive picture of a student's ability in anatomy. Copyright © 2011 American Association of Anatomists.

  18. The production of anatomical teaching resources using three-dimensional (3D) printing technology. (United States)

    McMenamin, Paul G; Quayle, Michelle R; McHenry, Colin R; Adams, Justin W


    The teaching of anatomy has consistently been the subject of societal controversy, especially in the context of employing cadaveric materials in professional medical and allied health professional training. The reduction in dissection-based teaching in medical and allied health professional training programs has been in part due to the financial considerations involved in maintaining bequest programs, accessing human cadavers and concerns with health and safety considerations for students and staff exposed to formalin-containing embalming fluids. This report details how additive manufacturing or three-dimensional (3D) printing allows the creation of reproductions of prosected human cadaver and other anatomical specimens that obviates many of the above issues. These 3D prints are high resolution, accurate color reproductions of prosections based on data acquired by surface scanning or CT imaging. The application of 3D printing to produce models of negative spaces, contrast CT radiographic data using segmentation software is illustrated. The accuracy of printed specimens is compared with original specimens. This alternative approach to producing anatomically accurate reproductions offers many advantages over plastination as it allows rapid production of multiple copies of any dissected specimen, at any size scale and should be suitable for any teaching facility in any country, thereby avoiding some of the cultural and ethical issues associated with cadaver specimens either in an embalmed or plastinated form. © 2014 American Association of Anatomists.

  19. Plastination: ethical and medico-legal considerations

    Directory of Open Access Journals (Sweden)

    Bin Paola


    Full Text Available The international plastination phenomenon has proved to be immensely popular with audiences world-wide. Never before has the human body been exposed to public gaze in such an accessible manner. The exhibitions have perplexed many, included anatomists, some of whom find the display of human bodies unethical. The objective of this study is to review the attention on the use of plastination and exhibition of entire human bodies for non-educational or commercial purposes. The nature of these exhibitions and the uneasy balance between entertainment and education has caused heated debate. The possible legitimacy of the expression of one’s will as far as exhibition purposes isn’t considered sufficient for the indiscriminate use of a corpse despite the ethical necessity of respecting the wishes of individuals based on respect for the deceased. The informed consent of an individual represents only the most basic and minimal prerequisite for the use of the deceased’s body for exhibition purposes, and is absolutely not enough on its own to justify its use in entertainment exhibitions or for the commercialization of the death

  20. Henry Gray, plagiarist. (United States)

    Richardson, Ruth


    The first edition of Anatomy Descriptive and Surgical (1858) was greeted with accolades, but also provoked serious controversy concerning Henry Gray's failure to acknowledge the work of earlier anatomists. A review in the Medical Times (1859) accused Gray of intellectual theft. The journal took the unusual step of substantiating its indictment by publishing twenty parallel texts from Gray and from a pre-existing textbook, Quain's Anatomy. At the recent "Vesalius Continuum" conference in Zakynthos, Greece (2014) Professor Brion Benninger disputed the theft by announcing from the floor the results of a computer analysis of both texts, which he reported exonerated Gray by revealing no evidence of plagiarism. The analysis has not been forthcoming, however, despite requests. Here the historian of Gray's Anatomy supplements the argument set out in the Medical Times 150 years ago with data suggesting unwelcome personality traits in Henry Gray, and demonstrating the utility of others' work to his professional advancement. Fair dealing in the world of anatomy and indeed the genuineness of the lustre of medical fame are important matters, but whether quantitative evidence has anything to add to the discussion concerning Gray's probity can be assessed only if Benninger makes public his computer analysis. © 2015 Wiley Periodicals, Inc.

  1. The Origin of Species, Man's Place in Nature and the naming of the calcarine sulcus. (United States)

    Fishman, R S


    In The Origin of Species by Means of Natural Selection of 1859, Charles Darwin provided a detailed, coherent proposal: species changed into new ones by the action over time of natural forces in the environment acting continuously on the variations always present within species. Readers immediately extrapolated Darwin's argument concerning lower animals to the implications for humans, and its denial of a special creation of humans. In opposition to Darwin's theory, Britain's preeminent paleontologist and comparative anatomist, Richard Owen, argued that man was unique among all creation in the possession of a particular structure within the brain, the 'Hippocampus minor'. Darwin's great defender, Thomas Huxley, demonstrated that this structure also existed in monkeys and apes, and that it was simply a manifestation of a 'particular sulcus' in the posterior cerebral cortex, which he named as the 'calcarine' sulcus. The home of the visual striate cortex was thus named as part of the controversy surrounding the birth of evolutionary theory, soon to be accepted as the great unifying concept in all of biology.

  2. Transforming clinical imaging and 3D data for virtual reality learning objects: HTML5 and mobile devices implementation. (United States)

    Trelease, Robert B; Nieder, Gary L


    Web deployable anatomical simulations or "virtual reality learning objects" can easily be produced with QuickTime VR software, but their use for online and mobile learning is being limited by the declining support for web browser plug-ins for personal computers and unavailability on popular mobile devices like Apple iPad and Android tablets. This article describes complementary methods for creating comparable, multiplatform VR learning objects in the new HTML5 standard format, circumventing platform-specific limitations imposed by the QuickTime VR multimedia file format. Multiple types or "dimensions" of anatomical information can be embedded in such learning objects, supporting different kinds of online learning applications, including interactive atlases, examination questions, and complex, multi-structure presentations. Such HTML5 VR learning objects are usable on new mobile devices that do not support QuickTime VR, as well as on personal computers. Furthermore, HTML5 VR learning objects can be embedded in "ebook" document files, supporting the development of new types of electronic textbooks on mobile devices that are increasingly popular and self-adopted for mobile learning. © 2012 American Association of Anatomists.

  3. [History of pneumology in antiquity (part 2)]. (United States)

    Demaeyer, Ph


    Nowadays, Hippocrate, "The Father of Medicine", still influences our medicine. He was famous because of the great medical corpus texts preserved in his name. Only recently, our universities have updated the famous Hippocratic Oath to avoid contradictions with our modern ethics. Hippocrate was a great clinician but a poor anatomist. Hippocratical humourism remained accurate until the age of the enlightenment (18th century). Furthermore, it is difficult to distinguish medicine from philosophy in Greek antiquity. So we have to contextualize Greek ancient medicine in this philosophical field. In the 3rd century before Christus (BC), the centre of gravity in medicine shifted to Alexandria. Indeed, a famous academic library was created in 288 BC. At the same time, dissection of human cadavers was authorized until the first century BC. This enabled the evolution of the knowledge in anatomy and physiology. Rome was still polytheistic population until the end of ancient times. Rome integrated Greek gods in his pantheon. Asclepios became Aesculapius. Rome despises physicians in the first ancient age of Rome. The family's father provided medical cares. A lot of Greek physicians settled then in Rome. Again, roman medicine grew in parallel with philosophical trends. These trends were called "sects" but in fact, they were rather medical schools. In this review, we will especially talk about three physicians of this period: Aurelius Cornelius Celsus, Arétée of Cappadocia and Galenus of Pergamon. Thereafter, medical knowledge did not really change significantly until Renaissance period.

  4. Are the alleged remains of Johann Sebastian Bach authentic? (United States)

    Zegers, Richard H C; Maas, Mario; Koopman, A Ton G; Maat, George J R


    A skeleton alleged to be that of Johann Sebastian Bach (1685-1750) was exhumed from a graveyard in Leipzig, Germany, in 1894, but its authenticity is not established. In 1895, anatomist Wilhelm His concluded from his examination of the skeleton and reconstruction of the face that it most likely belonged to Bach. In 1949, surgeon Wolfgang Rosenthal noticed exostoses on the skeleton and on x-rays of 11 living organists and proposed a condition, Organistenkrankheit, which he interpreted as evidence that the skeleton was Bach's. However, our critical assessment of the remains analysis raises doubts: the localisation of the grave was dubious, and the methods used by His to reconstruct the face are controversial. Also, our study of the pelvic x-rays of 12 living professional organists failed to find evidence for the existence of Organistenkrankheit. We believe it is unlikely that the skeleton is that of Bach; techniques such as DNA analysis might help resolve the question but, to date, church authorities have not approved their use on the skeleton.

  5. Neura, nerves, nerve fibers, neurofibrils, microtubules: multidimensional routes of pain, pleasure, and voluntary action in images across the ages. (United States)

    Frixione, Eugenio


    Available records indicate that the human body has always been conceived, in different periods and cultures, as spanned by multiple channels for internal communication and coherent functioning as a unit-"meridians" in treatises of Chinese medicine, metu in Egyptian papyri, srotas in Ayurvedic Indian texts, and neura in the Western scientific heritage from ancient Greece. Unfortunately, the earliest extant figurative depictions of such pathways of general control, complementary to the blood vessels, are late medieval copies of old crude sketches that attempted to show the main anatomico-physiological systems. The scarcity of adequate illustrations was more than compensated in the Renaissance, when the efforts of both artists and anatomists for the first time produced basically correct renditions of the human nervous system and many other bodily structures. As attention was next focused on microscopic structure as a requisite to understand physiological mechanisms, during the Enlightenment the nerves were revealed to consist of numerous thin tubes or fibers aligned in parallel. Improved microscopy techniques in the nineteenth century led to discovering and delineating still finer fibrils coursing along the cores of the nerve fibers themselves. Electron microscopy, developed throughout the twentieth century, recognized some of these fibrils within nerve fibers as being also tubular. All the progressive stages in understanding nerve construction, at increasingly more detailed scales, have been accompanied by technological advances and by debate about the structure and function relationship. And every step has been a source of amazing imagery. © 2013 Elsevier B.V. All rights reserved.

  6. Josef Klingler's models of white matter tracts: influences on neuroanatomy, neurosurgery, and neuroimaging. (United States)

    Agrawal, Abhishek; Kapfhammer, Josef P; Kress, Annetrudi; Wichers, Hermann; Deep, Aman; Feindel, William; Sonntag, Volker K H; Spetzler, Robert F; Preul, Mark C


    During the 1930s, white matter tracts began to assume relevance for neurosurgery, especially after Cajal's work. In many reviews of white matter neurobiology, the seminal contributions of Josef Klingler (1888-1963) and their neurological applications have been overlooked. In 1934 at the University of Basel under Eugen Ludwig, Klingler developed a new method of dissection based on a freezing technique for brain tissue that eloquently revealed the white matter tracts. Klingler worked with anatomists, surgeons, and other scientists, and his models and dissections of white matter tracts remain arguably the most elegant ever created. He stressed 3-dimensional anatomic relationships and laid the foundation for defining mesial temporal, limbic, insular, and thalamic fiber and functional relationships and contributed to the potential of stereotactic neurosurgery. Around 1947, Klingler was part of a Swiss-German group that independently performed the first stereotactic thalamotomies, basing their targeting and logic on Klingler's white matter studies, describing various applications of stereotaxy and showing Klingler's work integrated into a craniocerebral topographic system for targeting with external localization of eloquent brain structures and stimulation of deep thalamic nuclei. Klingler's work has received renewed interest because it is applicable for correlating the results of the fiber-mapping paradigms from diffusion tensor imaging to actual anatomic evidence. Although others have described white matter tracts, none have had as much practical impact on neuroscience as Klinger's work. More importantly, Josef Klingler was an encouraging mentor, influencing neurosurgeons, neuroscientists, and brain imaging for more than three quarters of a century.

  7. Freud and evolution. (United States)

    Scharbert, Gerhard


    The essay analyzes the influence of evolutionary thought in the work of Sigmund Freud. Based on Freud's initial occupation as a neuro-anatomist and physiologist certain aspects stemming from the history of nature and developmental biological reasoning that played a role in his endeavours to find a new basis for medical psychology will be pointed out. These considerations are to be regarded as prolegomena of the task to reread Freud once again, and in doing so avoiding the verdict that holds his neuro-anatomic and comparative-morphological works as simply "pre-analytic." In fact, the time seems ripe to reconsider in a new context particularly those evolutionary, medical, and cultural-scientific elements in Freud's work that appear inconsistent at first sight. The substantial thesis is that Freud, given the fact that he was trained in comparative anatomy and physiology in the tradition of Johannes Müller, had the capability of synthesizing elements of this new point of view with the findings and interrogations concerning developmental history and the theory of evolution. More over, this was perceived not merely metaphoric, as he himself stressed it (Freud 1999, XIII, 99), but in the sense of Ubertragung, that inscribed terms and methods deriving from the given field into the realm of psychology. The moving force behind this particular Ubertragung came from a dynamically-neurological perception of the soul that emerged in France since 1800, which Freud came to know trough the late work of Charcot.

  8. Developing a Korean standard brain atlas on the basis of statistical and probabilistic approach and visualization tool for functional image analysis

    Koo, B. B.; Lee, J. M.; Kim, J. S.; Kim, I. Y.; Kim, S. I.; Lee, J. S.; Lee, D. S.; Kwon, J. S.; Kim, J. J.


    The probabilistic anatomical maps are used to localize the functional neuro-images and morphological variability. The quantitative indicator is very important to inquire the anatomical position of an activated region because functional image data has the low-resolution nature and no inherent anatomical information. Although previously developed MNI probabilistic anatomical map was enough to localize the data, it was not suitable for the Korean brains because of the morphological difference between Occidental and Oriental. In this study, we develop a probabilistic anatomical map for Korean normal brain. Normal 75 brains of T1-weighted spoiled gradient echo magnetic resonance images were acquired on a 1.5-T GESIGNA scanner. Then, a standard brain is selected in the group through a clinician searches a brain of the average property in the Talairach coordinate system. With the standard brain, an anatomist delineates 89 regions of interest (ROI) parcellating cortical and subcortical areas. The parcellated ROIs of the standard are warped and overlapped into each brain by maximizing intensity similarity. And every brain is automatically labeled with the registered ROIs. Each of the same-labeled region is linearly normalize to the standard brain, and the occurrence of each region is counted. Finally, 89 probabilistic ROI volumes are generated. This paper presents a probabilistic anatomical map for localizing the functional and structural analysis of Korean normal brain. In the future, we'll develop the group specific probabilistic anatomical maps of OCD and schizophrenia disease

  9. Cell biology solves mysteries of reproduction. (United States)

    Sutovsky, Peter


    Reproduction and fertility have been objects of keen inquiry since the dawn of humanity. Medieval anatomists provided the first accurate depictions of the female reproductive system, and early microscopists were fascinated by the magnified sight of sperm cells. Initial successes were achieved in the in vitro fertilization of frogs and the artificial insemination of dogs. Gamete and embryo research was in the cradle of modern cell biology, providing the first evidence of the multi-cellular composition of living beings and pointing out the importance of chromosomes for heredity. In the 20th century, reproductive research paved the way for the study of the cytoskeleton, cell signaling, and the cell cycle. In the last three decades, the advent of reproductive cell biology has brought us human in vitro fertilization, animal cloning, and human and animal embryonic stem cells. It has contributed to the development of transgenesis, proteomics, genomics, and epigenetics. This Special Issue represents a sample of the various areas of reproductive biology, with emphasis on molecular and cell biological aspects. Advances in spermatology, ovarian function, fertilization, and maternal-fetal interactions are discussed within the framework of fertility and diseases such as endometriosis and diabetes.

  10. History of the discovery of neuronal death in embryos. (United States)

    Hamburger, V


    The German anatomists, M. Ernst and A. Glücksmann, deserve credit for the discovery of widespread cell death in embryonic tissues, including the nervous tissue. In 1934, V. Hamburger described a significant hypoplasia in dorsal root ganglia (DGR) and lateral motor columns, following the extirpation of limb buds in chick embryos. In the early 1940s, Dr. Rita Levi-Montalcini in Turin (Italy) repeated the experiment and suggested that the hypoplasia might result from the death of young differentiated neurons. In a joint reinvestigation, published in 1949, large numbers of degenerating neurons were described in brachial DRG, following wing bud extirpations. In the same embryos, Dr. Levi-Montalcini observed massive neuronal death in cervical and thoracic DRG which had not been affected by the operation. This was the discovery of naturally occurring neuronal death. Long after the discovery of Nerve Growth Factor (NGF) it was recognized that NGF and natural neuronal death are two sides of the same coin: the latter results from an insufficient supply of the former by the target tissues.

  11. The Anatomical Institute at the University of Greifswald during National Socialism: The procurement of bodies and their use for anatomical purposes. (United States)

    Alvermann, Dirk; Mittenzwei, Jan


    This is the first comprehensive account of body procurement at the Anatomical Institute at Greifswald University during National Socialism (NS). As in all other German anatomical departments, the bodies received during this period included increasing numbers of victims of the NS regime. Prior to 1939, 90% of all bodies came from hospitals, state nursing homes and mental institutions (Heil- und Pflegeanstalten), but dropped to less than 30% after 1941. While the total catchment area for body procurement decreased, the number of suppliers increased and included prisons, POW camps, Gestapo offices and military jurisdiction authorities. Among the 432 documented bodies delivered to the institute, 132 came from state nursing homes and mental institutions, mainly from Ueckermünde. These were bodies of persons, who probably were victims of "euthanasia" crimes. The Anatomical Institute also procured 46 bodies of forced laborers, of whom at least twelve had been executed. Other groups of victims included 21 bodies of executed Wehrmacht soldiers and 16 Russian prisoners of war from the camp Stalag II C in Greifswald, who had died of starvation and exhaustion. From 1941 onwards, the number of bodies delivered from prisons and penitentiaries greatly increased. In total, 60 bodies of prisoners, mainly from the penitentiary in Gollnow, were delivered to the Anatomical Institute. Greifswald Anatomical Institute was not just a passive recipient of bodies from all of these sources, but the anatomists actively lobbied with the authorities for an increased body supply for teaching and research purposes.

  12. Anatomical departments in Bavaria and the corpses of executed victims of National Socialism. (United States)

    Noack, Thorsten


    While it is known that the bodies of executed victims of National Socialism (NS) were used for anatomical research and teaching, detailed studies are still missing for many anatomical departments. This analysis focuses on the institutes in Bavaria. From 1933 on the institutes of Munich, Würzburg and Erlangen were actively involved in and competed over the procurement of bodies of NS victims, particularly between 1937 and 1941. While the body supply was sufficient thereafter it became again critical in the first years after the war. During that period, anatomists complained about a lack of bodies for dissection courses and tended to use the corpses remaining from the NS-period for teaching purposes. Their position was supported by the popular view that resistance fighters were seen as traitors to the Fatherland and not as honorable political victims. At the same time, relatives and aid organizations were in search of the dead victims of German terror. These conflicting interests created a situation full of tension, in which Philipp Auerbach, state commissioner for religious, political and racial victims of the Nazis in Bavaria, played a crucial role.

  13. The Munich Anatomical Institute under National Socialism. First results and prospective tasks of an ongoing research project. (United States)

    Schütz, Mathias; Waschke, Jens; Marckmann, Georg; Steger, Florian


    While research into the history of German anatomy under National Socialist rule has increased during the last decade, the story of one of the most important anatomical institutes of the time, the Anatomische Anstalt Munich, has not yet been explored. This study presents the results of an ongoing, cooperative research project at the universities of Halle and Munich and focuses on the history of the institution, its personnel and organization, and its interactions with the National Socialist regime. It reveals continuity and disruption within the institute following Munich anatomists' involvement with the regime's policies and ideology as well as their becoming victims to these policies. Also documented is the manner in which the Munich anatomy benefited from the massive increase in executions, especially during the Second World War, by receiving and using the bodies of prisoners executed at the Stadelheim prison in Munich for scientific purposes. Finally, an outlook is presented regarding planned research aiming to fully understand the history of the Anatomische Anstalt during National Socialism. Copyright © 2013 Elsevier GmbH.

  14. Development and assessment of a new 3D neuroanatomy teaching tool for MRI training. (United States)

    Drapkin, Zachary A; Lindgren, Kristen A; Lopez, Michael J; Stabio, Maureen E


    A computerized three-dimensional (3D) neuroanatomy teaching tool was developed for training medical students to identify subcortical structures on a magnetic resonance imaging (MRI) series of the human brain. This program allows the user to transition rapidly between two-dimensional (2D) MRI slices, 3D object composites, and a combined model in which 3D objects are overlaid onto the 2D MRI slices, all while rotating the brain in any direction and advancing through coronal, sagittal, or axial planes. The efficacy of this tool was assessed by comparing scores from an MRI identification quiz and survey in two groups of first-year medical students. The first group was taught using this new 3D teaching tool, and the second group was taught the same content for the same amount of time but with traditional methods, including 2D images of brain MRI slices and 3D models from widely used textbooks and online sources. Students from the experimental group performed marginally better than the control group on overall test score (P = 0.07) and significantly better on test scores extracted from questions involving C-shaped internal brain structures (P teaching tool is an effective way to train medical students to read an MRI of the brain and is particularly effective for teaching C-shaped internal brain structures. © 2015 American Association of Anatomists.


    Velenciuc, I; Minea, Raluca; Duceac, Letiţia; Vlad, T


    The present paper aims, exploring the history of Renaissance medicine, to evoke the figure and work of the priest, surgeon and anatomist, Guido Guidi (Vidus Vidius) (1509-1569). The XVIth century is considered a period marked by artistic and scientific effervescence in the western part of Europe and Guido Guidi was a first order personality, grandson of Domenico Ghirlandaio and friend of Benvenuto Cellini. He was appointed by the King Francis I the first professor of anatomy and surgery at the newly founded College de France. On demand of the King, he wrote Chirurgia j Graeco in Latinum conversa Vido Vidio Florentino interprete, cum nonnullis eiusdem Vidii comentariis (1544), a beautifully illustrated original surgery book that became for the following two centuries the main source in teaching surgery. Our study realized a detailed assessment of the book and especially of its illustrations belonging to Francesco Salviati. Exploring the life of Guido Guidi, we were also able to point out other significant contributions in the field of anatomy and clinical medicine as De anatome the first book where are presented disarticulated, the bones of the skull base and also the discovery of the chickenpox. Some surgical personalities attributed to him both the elaboration of the term appendix vermiformis and the first description of an aneurysm, he treated with the help of Fallopio. Although forgotten today, Guido Guidi was a leading figure of the Renais sance medicine both in France and Italy.

  16. The Oculist's Eye: Connections between Cataract Couching, Anatomy, and Visual Theory in the Renaissance. (United States)

    Baker, Tawrin


    We now know that cataract couching involves depressing an occluded crystalline lens to the bottom of the vitreous chamber, but from the time of Galen until the seventeenth-century cataracts were thought to be separate concretions arising between the crystalline lens and the pupil. From Antiquity through the Renaissance, the combination of visual theory in which the crystalline humor is the author of vision, and surgical experience—that couching cataracts restored some degree of sight—resulted in anatomists depicting a large space between the crystalline lens and the pupil. In the Renaissance, oculists—surgical specialists with little higher education or connections to learned surgery or medicine—overwhelmingly performed eye surgeries. This article examines how the experience and knowledge of oculists, of barber-surgeons, and of learned surgeons influenced one another on questions of anatomy, visual theory, and surgical experience. By analyzing the writings of the oculist George Bartisch (c. 1535–1607), the barber-surgeon Ambroise Paré (1510–1590), and the learned surgeon Hieronymus Fabricius ab Aquapendente (1533–1619), we see that the oculists’ understanding of the eye—an eye constructed out of the probing, tactile experience of eye surgery—slowly lost currency among the learned toward the beginning of the seventeenth century.

  17. Galen and the beginnings of Western physiology. (United States)

    West, John B


    Galen (129-c. 216 AD) was a key figure in the early development of Western physiology. His teachings incorporated much of the ancient Greek traditions including the work of Hippocrates and Aristotle. Galen himself was a well-educated Greco-Roman physician and physiologist who at one time was a physician to the gladiators in Pergamon. Later he moved to Rome, where he was associated with the Roman emperors Marcus Aurelius and Lucius Verus. The Galenical school was responsible for voluminous writings, many of which are still extant. One emphasis was on the humors of the body, which were believed to be important in disease. Another was the cardiopulmonary system, including the belief that part of the blood from the right ventricle could enter the left through the interventricular septum. An extraordinary feature of these teachings is that they dominated thinking for some 1,300 years and became accepted as dogma by both the State and Church. One of the first anatomists to challenge the Galenical teachings was Andreas Vesalius, who produced a magnificent atlas of human anatomy in 1543. At about the same time Michael Servetus described the pulmonary transit of blood, but he was burned at the stake for heresy. Finally, with William Harvey and others in the first part of the 17th century, the beginnings of modern physiology emerged with an emphasis on hypotheses and experimental data. Nevertheless, vestiges of Galen's teaching survived into the 19th century. Copyright © 2014 the American Physiological Society.

  18. The women of Salerno: contribution to the origins of surgery from medieval Italy. (United States)

    Ferraris, Z A; Ferraris, V A


    Medicine in medieval Europe benefited from Greek, Arabic, Hebrew, and Latin influences. Because of geographic and other favorable conditions, many of these cultural contributions synergized to form the Medical School at Salerno around 900 AD. Somewhat uncharacteristically, women physicians played a part in the advances that came from this school. Among the contributions associated with the School of Salerno were (1) textbooks of anatomy, obtained mainly from porcine dissections, (2) insistence on certification and training for physicians, (3) application of investigative thinking and deduction that led to important advances such as the use of healing by secondary intention, (4) the first textbook about women's medicine, and (5) the first recorded female medical school faculty member named Trotula de Ruggiero or Trocta Salernitana. The women physicians of Salerno contributed to a textbook that gained wide acceptance and distribution throughout Europe. The textbook, called De Passionibus Mulierium, was first published about 1100 AD and was a prominent text until a significant revision by Ambrose Paré's assistant in the early 1600s. Paré was the preeminent anatomist of his time, and many of his important anatomic and surgical considerations were directly and indirectly derived from the work of the women of Salerno. The advances first recorded, taught, and implemented by the women of Salerno are an interesting and important part of our surgical heritage.

  19. A Marble Embryo: Meanings of a Portrait from 1900 (United States)

    Hopwood, Nick


    Portraits of scientists use attributes of discovery to construct identities; portraits that include esoteric accessories may fashion identities for these too. A striking example is a marble bust of the anatomist Wilhelm His by the Leipzig sculptor Carl Seffner. Made in 1900, it depicts the founder of modern human embryology looking down at a model embryo in his right hand. This essay reconstructs the design and viewing of this remarkable portrait in order to shed light on private and public relations between scientists, research objects and audiences. The bust came out of a collaboration to model the face of the composer Johann Sebastian Bach and embodies a shared commitment to anatomical exactitude in three dimensions. His’s research agendas and public character explain the contemplative pose and unprecedented embryo model, which he had laboriously constructed from material a midwife supplied. The early contexts of display in the His home and art exhibitions suggest interpretive resources for viewers and hence likely meanings. Seffner’s work remains exceptional, but has affinities to portraits of human embryologists and embryos produced since 1960. Embryo images have acquired such controversial prominence that the model may engage us more strongly now than it did exhibition visitors around 1900. PMID:22606754

  20. Rectal mobilization: the place of Denonvilliers' fascia and inconsistencies in the literature. (United States)

    Chapuis, P H; Kaw, A; Zhang, M; Sinclair, G; Bokey, L


    Confusion remains as to what is meant by Denonvilliers' fascia. This review searched the literature on pelvic surgical anatomy to determine whether there is agreement with Denonvilliers' original description and its implication in defining the correct anterior plane of dissection when mobilizing the rectum. The original French description of the fascia was translated into English and then compared both with French and with English studies identified by searching PubMed, Medline and Scopus from 1836 to June 2015. Special emphasis was given to the years between 1980 and 2015 in order to capture the literature pertinent to, and following on from, the description of total mesorectal excision for rectal cancer. The final literature search revealed 16 studies from the original 2150 citations. Much of the debate was concerned with the origin and development of the fascia, arising from either the 'fusion' or the 'condensation' of local primitive tissue into a mature 'multilayered' structure. Controversy regarding the correct plane of rectal mobilization occurs as a result of different interpretations by surgeons, anatomists and radiologists and bears little resemblance to Denonvilliers' original description. This may reflect wide anatomical variability in the adult pelvis or a form of dissection artefact. Further study is required to investigate this. Logically, for both men and women, the plane of rectal mobilization should be behind Denonvilliers' fascia and between it and the fascia propria of the rectum.

  1. Biomechanical origin of the Denonvilliers' fascia. (United States)

    Bertrand, M M; Alsaid, B; Droupy, S; Benoit, G; Prudhomme, M


    Since 1836 and the first description of the recto-genital fascia by Charles Denonvilliers, many anatomists have shown interest in this subject. Recently, pelvic surgeons have in turn shown similar interest, for they consider that perfect knowledge of this anatomical domain is crucial for optimal nerve conservation during surgery. Thanks to new anatomical description techniques, fascia location and relationships with pelvic nerves now appear clearer. To describe and represent Denonvilliers' fascia and its relationships in the female foetus at different stages of gestation and in three-dimensional space (3D). Computer-assisted anatomical dissection technique was used. Serial histological sections were made from four human female foetuses. Sections were treated with conventional staining, as well as with nerve and smooth muscle immunostaining. Finally, the sections were digitalized and reconstructed in 3D. Denonvilliers' fascia was clearly located and visualized in three dimensions. It was present in the female foetus, being distinct from the fascia propria of the rectum. It appeared to be composed of multiple parallel layers situated between the vagina and the rectum. From a lateral view, it had an asymmetrical "Y-shaped" aspect that seemed to play the role of a protective sheet for the neurovascular bundles. This study betters our comprehension of the Denonvilliers' fascia in the female foetus and of its connections with pelvic nerves. It also provides a better understanding of safe planes during pelvic dissection. These findings also suggest a biomechanical theory for embryological origin of the Denonvilliers' fascia.

  2. Applied neuroanatomy elective to reinforce and promote engagement with neurosensory pathways using interactive and artistic activities. (United States)

    Dao, Vinh; Yeh, Pon-Hsiu; Vogel, Kristine S; Moore, Charleen M


    One in six Americans is currently affected by neurologic disease. As the United States population ages, the number of neurologic complaints is expected to increase. Thus, there is a pressing need for more neurologists as well as more neurology training in other specialties. Often interest in neurology begins during medical school, so improving education in medical neural courses is a critical step toward producing more neurologists and better neurology training in other specialists. To this end, a novel applied neuroanatomy elective was designed at the University of Texas Health Science Center at San Antonio (UTHSCSA) to complement the traditional first-year medical neuroscience course and promote engagement and deep learning of the material with a focus on neurosensory pathways. The elective covered four neurosensory modalities (proprioception/balance, vision, auditory, and taste/olfaction) over four sessions, each with a short classroom component and a much longer activity component. At each session, students reviewed the neurosensory pathways through structured presentations and then applied them to preplanned interactive activities, many of which allowed students to utilize their artistic talents. Students were required to complete subjective pre-course and post-course surveys and reflections. The survey results and positive student comments suggest that the elective was a valuable tool when used in parallel with the traditional medical neuroscience course in promoting engagement and reinforcement of the neurosensory material. © 2014 American Association of Anatomists.

  3. Chapter 20: neurological illustration from photography to cinematography. (United States)

    Aubert, Geneviève


    This chapter explores iconography in neurology from the birth of photography up to the early medical applications of cinematography before 1914. The important visual part of neurological diagnosis explains why these techniques were adopted very early by neurologists. Duchenne published the first medical book illustrated with photographs of patients. The first and most famous photographic laboratory was created in Charcot's department, at the Salpêtrière in Paris, under the direction of Albert Londe. Londe published the first book dedicated to medical photography. The physiologist Marey and the photographer Muybridge, in association with neurologists, played key roles in the development of chronophotography and cinematography. Germany was the first country to welcome cinematography in a neurology department. Independently, neurologists began to film patients in other countries in Europe and in America. In 1905, Arthur Van Gehuchten (1861-1914), Belgian anatomist and neurologist, began systematically to film neurologic patients, with the intention of building up a complete neurological iconographic collection. This collection has survived and has been restored in the laboratory of the Royal Belgian Film Archive where the films are now safely stored in their vaults.

  4. Interprofessional anatomy education in the United Kingdom and Ireland: Perspectives from students and teachers. (United States)

    Smith, Claire F; Hall, Samuel; Border, Scott; Adds, Philip J; Finn, Gabrielle M


    There is increasing recognition of multiprofessional learning in anatomy and its role in medical and healthcare professions. This study utilized two components to investigate anatomy interprofessional education (AIPE) in the United Kingdom and Ireland. First, a survey involving qualitative and quantitative components asked Heads of Anatomy to report on their institutions' uptake of AIPE. Second, a series of case studies explored the experiences of students by using evaluation forms and an in-depth analysis of thematic concepts to understand the learners' perspectives on designing and delivering AIPE. Out of the 13 institutions that took part in the survey, eight did not offer an AIPE program. Between the remaining five institutions that deliver AIPE programs, 10 different modules are offered with the majority involving healthcare professions. The AIPE component is rated highly by students. The themes from the case studies highlight how valuable AIPE is from the student perspective both in terms of engaging them in anatomy as well as in the broader skills of teamwork and communication. The case studies also revealed how AIPE can be engaging for groups of students who might not have previously had access to cadaveric anatomy, for example, engineers and archeologists. The results of this study have implications for curriculum design in medicine and healthcare but also for further engagement of professional groups from non-healthcare backgrounds. © 2015 American Association of Anatomists.

  5. Incorporating gross anatomy education into radiation oncology residency: a 2-year curriculum with evaluation of resident satisfaction. (United States)

    Cabrera, Alvin R; Lee, W Robert; Madden, Richard; Sims, Ershela; Hoang, Jenny K; White, Leonard E; Marks, Lawrence B; Chino, Junzo P


    Radiation oncologists require a thorough understanding of anatomy, but gross anatomy is not part of the standard residency curriculum. "Oncoanatomy" is an educational program for radiation oncology residents at Duke University that integrates cadaver dissection into the instruction of oncologic anatomy, imaging, and treatment planning. In this report, the authors document their experience with a 2-year curriculum. Nineteen radiation oncology residents from Duke University and the University of North Carolina participated during academic years 2008-2009 and 2009-2010. Monthly modules, based on anatomic site, consisted of one or two clinically oriented hour-long lectures, followed by a 1-hour gross anatomy session. Clinical lectures were case based and focused on radiographic anatomy, image segmentation, and field design. Gross anatomy sessions centered on cadaver prosections, with small groups rotating through stations at which anatomists led cadaver exploration. Adjacent monitors featured radiologic imaging to facilitate synthesis of gross anatomy with imaging anatomy. Satisfaction was assessed on a 10-point scale via anonymous survey. Twenty modules were held over the 2-year period. Participants gave the course a median rating of 8 (interquartile range, 7-9), with 1 signifying "as effective as the worst educational activities" and 10 "as effective as the best educational activities." High resident satisfaction was seen with all module components. Incorporating a structured, 2-year gross anatomy-based curriculum into radiation oncology residency is feasible and associated with high resident satisfaction.

  6. Reflections as near-peer facilitators of an inquiry project for undergraduate anatomy: Successes and challenges from a term of trial-and-error. (United States)

    Anstey, Lauren M; Michels, Alison; Szymus, Julianna; Law, Wyanne; Edwin Ho, Man-Hymn; Qu, Fei; Yeung, Ralph T T; Chow, Natalie


    Near-peer facilitators (senior students serving as facilitators to their more junior peers) bring a unique student-based perspective to teaching. With fewer years of teaching experience however, students who become involved in a facilitator role typically develop related skills quickly through a process of trial-and-error within the classroom. The aim of this paper is to report on the authors' own experiences and reflections as student near-peer facilitators for an inquiry-based project in an undergraduate anatomy course. Three areas of the facilitator experience are explored: (1) offering adequate guidance as facilitators of inquiry, (2) motivating students to engage in the inquiry process, and (3) fostering creativity in learning. A practical framework for providing guidance to students is discussed which offers facilitators a scaffold for asking questions and assisting students through the inquiry process. Considerations for stimulating intrinsic motivations toward inquiry learning are made, paying attention to ways in which facilitators might influence feelings of motivation towards learning. Also, the role of creativity in inquiry learning is explored by highlighting the actions facilitators can take to foster a creative learning environment. Finally, recommendations are made for the development of formalized training programs that aid near-peer facilitators in the acquisition of facilitation skills before entering into a process of trial-and-error within the classroom. © 2013 American Association of Anatomists.

  7. Virtual reality anatomy: is it comparable with traditional methods in the teaching of human forearm musculoskeletal anatomy? (United States)

    Codd, Anthony M; Choudhury, Bipasha


    The use of cadavers to teach anatomy is well established, but limitations with this approach have led to the introduction of alternative teaching methods. One such method is the use of three-dimensional virtual reality computer models. An interactive, three-dimensional computer model of human forearm anterior compartment musculoskeletal anatomy was produced using the open source 3D imaging program "Blender." The aim was to evaluate the use of 3D virtual reality when compared with traditional anatomy teaching methods. Three groups were identified from the University of Manchester second year Human Anatomy Research Skills Module class: a "control" group (no prior knowledge of forearm anatomy), a "traditional methods" group (taught using dissection and textbooks), and a "model" group (taught solely using e-resource). The groups were assessed on anatomy of the forearm by a ten question practical examination. ANOVA analysis showed the model group mean test score to be significantly higher than the control group (mean 7.25 vs. 1.46, P traditional methods group (mean 6.87, P > 0.5). Feedback from all users of the e-resource was positive. Virtual reality anatomy learning can be used to compliment traditional teaching methods effectively.

  8. Evaluating the impact of a Canadian national anatomy and radiology contouring boot camp for radiation oncology residents. (United States)

    Jaswal, Jasbir; D'Souza, Leah; Johnson, Marjorie; Tay, KengYeow; Fung, Kevin; Nichols, Anthony; Landis, Mark; Leung, Eric; Kassam, Zahra; Willmore, Katherine; D'Souza, David; Sexton, Tracy; Palma, David A


    Radiation therapy treatment planning has advanced over the past 2 decades, with increased emphasis on 3-dimensional imaging for target and organ-at-risk (OAR) delineation. Recent studies suggest a need for improved resident instruction in this area. We developed and evaluated an intensive national educational course ("boot camp") designed to provide dedicated instruction in site-specific anatomy, radiology, and contouring using a multidisciplinary (MDT) approach. The anatomy and radiology contouring (ARC) boot camp was modeled after prior single-institution pilot studies and a needs-assessment survey. The boot camp incorporated joint lectures from radiation oncologists, anatomists, radiologists, and surgeons, with hands-on contouring instruction and small group interactive seminars using cadaveric prosections and correlative axial radiographs. Outcomes were evaluated using pretesting and posttesting, including anatomy/radiology multiple-choice questions (MCQ), timed contouring sessions (evaluated relative to a gold standard using Dice similarity metrics), and qualitative questions on satisfaction and perceived effectiveness. Analyses of pretest versus posttest scores were performed using nonparametric paired testing. Twenty-nine radiation oncology residents from 10 Canadian universities participated. As part of their current training, 29%, 75%, and 21% receive anatomy, radiology, and contouring instruction, respectively. On posttest scores, the MCQ knowledge scores improved significantly (pretest mean 60% vs posttest mean 80%, Pradiology in addition to enhancing their confidence and accuracy in contouring.

  9. Effectiveness and Complications of Percutaneous Needle Tenotomy with a Large Needle for Muscle Contractures: A Cadaver Study. (United States)

    Chesnel, Camille; Genêt, François; Almangour, Waleed; Denormandie, Philippe; Parratte, Bernard; Schnitzler, Alexis


    Twenty-two percent of institutionalised elderly persons have muscle contractures. Contractures have important functional consequences, rendering hygiene and positioning in bed or in a chair difficult. Medical treatment (such as botulinum toxin injections, physiotherapy or positioning) is not very effective and surgery may be required. Surgery is carried out in the operating theatre, under local or general anaesthesia but is often not possible in fragile patients. Mini-invasive tenotomy could be a useful alternative as it can be carried out in ambulatory care, under local anaesthesia. To evaluate the effectiveness of percutaneous needle tenotomy and the risks of damage to adjacent structures in cadavers. Thirty two doctors who had never practiced the technique (physical medicine and rehabilitation specialists, geriatricians and orthopaedic surgeons) carried out 401 tenotomies on the upper and lower limbs of 8 fresh cadavers. A 16G needle was used percutaneous following location of the tendons. After each tenotomy, a neuro-orthopaedic surgeon and an anatomist dissected the area in order to evaluate the success of the tenotomy and any adjacent lesions which had occurred. Of the 401 tenotomies, 72% were complete, 24.9% partial and 2.7% failed. Eight adjacent lesions occurred (2%): 4 (1%) in tendons or muscles, 3 (0.7%) in nerves and 1 (0.2%) in a vessel. This percutaneous needle technique effectively ruptured the desired tendons, with few injuries to adjacent structures. Although this study was carried out on cadavers, the results suggest it is safe to carry out on patients.

  10. Interprofessional approach for teaching functional knee joint anatomy. (United States)

    Meyer, Jakob J; Obmann, Markus M; Gießler, Marianne; Schuldis, Dominik; Brückner, Ann-Kathrin; Strohm, Peter C; Sandeck, Florian; Spittau, Björn


    Profound knowledge in functional and clinical anatomy is a prerequisite for efficient diagnosis in medical practice. However, anatomy teaching does not always consider functional and clinical aspects. Here we introduce a new interprofessional approach to effectively teach the anatomy of the knee joint. The presented teaching approach involves anatomists, orthopaedists and physical therapists to teach anatomy of the knee joint in small groups under functional and clinical aspects. The knee joint courses were implemented during early stages of the medical curriculum and medical students were grouped with students of physical therapy to sensitize students to the importance of interprofessional work. Evaluation results clearly demonstrate that medical students and physical therapy students appreciated this teaching approach. First evaluations of following curricular anatomy exams suggest a benefit of course participants in knee-related multiple choice questions. Together, the interprofessional approach presented here proves to be a suitable approach to teach functional and clinical anatomy of the knee joint and further trains interprofessional work between prospective physicians and physical therapists as a basis for successful healthcare management.

  11. The intermingled history of occupational therapy and anatomical education: A retrospective exploration. (United States)

    Carroll, Melissa A; Lawson, Katherine


    Few research articles have addressed the anatomical needs of entry-level occupational therapy students. Given this paucity of empirical evidence, there is a lack of knowledge regarding anatomical education in occupational therapy. This article will primarily serve as a retrospective look at the inclusion of anatomical education in the occupational therapy curriculum. Focusing on the historical inclusion is the first step to address the gap in existing knowledge. Examining the history of anatomy in occupational therapy provides an educational context for curricular developments and helps current anatomical educators understand the evolution of occupational therapy as a profession. Exploring the educational history also offers anatomy educators an identity, as significant contributors, in the training and preparedness of entry-level professionals while focusing on the ideals of occupational therapy. However, there is a critical need for empirical evidence of best teaching practices in occupational therapy and anatomical education. This manuscript provides a foundation and a starting point for further investigation into the anatomical competencies for entry-level occupational therapists. © 2014 American Association of Anatomists.

  12. Distinct roles for hu li tai shao and swallow in cytoskeletal organization during Drosophila oogenesis. (United States)

    Pokrywka, Nancy Jo; Zhang, Huadi; Raley-Susman, Kathleen


    Cytoskeletal organization is essential for localization of developmentally significant molecules during Drosophila oogenesis. Swallow (Swa) and an isoform of Hu li tai shao (Ovhts-RC) have been implicated in the organization of actin filaments in developing oocytes but their precise roles have been obscured by the dependence of hts RNA localization on swa function. The functional significance of hts RNA localization in the oocyte has not been established. In this study we examine Ovhts-RC distribution and cytoskeletal organization under conditions in which Swa protein and/or hts RNA localization are perturbed. We find Swa is required for overall actin organization and for the maintenance of a distinct subset of microtubules in the oocyte. hts RNA localization modulates the distribution of Ovhts-RC in the oocyte and, in turn, local actin filament proliferation. Our results support separate contributions of Swa and hts RNA localization to actin organization during oogenesis. Swa is crucial for the organization of actin networks that lead to the formation of a specialized microtubule population, while Ovhts-RC acts to modulate spatially restricted actin filament growth at the oocyte cortex. This suggests RNA localization can lead to modifications of both the actin and microtubule cytoskeletons at specific subcellular locales. © 2014 The Authors Developmental Dynamics published by Wiley Periodicals, Inc. on behalf of American Association of Anatomists.

  13. A tool for teaching three-dimensional dermatomes combined with distribution of cutaneous nerves on the limbs. (United States)

    Kooloos, Jan G M; Vorstenbosch, Marc A T M


    A teaching tool that facilitates student understanding of a three-dimensional (3D) integration of dermatomes with peripheral cutaneous nerve field distributions is described. This model is inspired by the confusion in novice learners between dermatome maps and nerve field distribution maps. This confusion leads to the misconception that these two distribution maps fully overlap, and may stem from three sources: (1) the differences in dermatome maps in anatomical textbooks, (2) the limited views in the figures of dermatome maps and cutaneous nerve field maps, hampering the acquisition of a 3D picture, and (3) the lack of figures showing both maps together. To clarify this concept, the learning process can be facilitated by transforming the 2D drawings in textbooks to a 3D hands-on model and by merging the information from the separate maps. Commercially available models were covered with white cotton pantyhose, and borders between dermatomes were marked using the drawings from the students' required study material. Distribution maps of selected peripheral nerves were cut out from color transparencies. Both the model and the cut-out nerve fields were then at the students' disposal during a laboratory exercise. The students were instructed to affix the transparencies in the right place according to the textbook's figures. This model facilitates integrating the spatial relationships of the two types of nerve distributions. By highlighting the spatial relationship and aiming to provoke student enthusiasm, this model follows the advantages of other low-fidelity models. © 2013 American Association of Anatomists.

    Full Text Available Pronator quadratus plays an important role in movement and stabilization of radius and ulna in distal radio-ulnar joint and used as a flap in traumatic injuries of the distal part of the forearm. Aim: The aim of this study was to delineate the morphology of pronator quadratus muscle. Material and methods: A total of 60 forearms (Rt- 30; Lt-30 from 30 Indian cadavers were evaluated. Careful dissection of each forearm was done and extent of radial and ulnar attachments of pronator quadratus, width of proximal and distal borders of it was taken. Also, observed additional heads, attachment of origin and insertion of pronator quadratus muscle. Results: Width of proximal and distal borders of pronator quadratus were 28.6mm and 30.2mm respectively on right side and on left it was 28.7mm and 30.1 mm respectively. It had a single head in 33.33%, double heads in 60.00% and three heads in 06.66%. Extents of its radial and ulnar attachments were 45.1 mm and 45.4 mm on right side and 45 mm and 45.5mm on left side respectively. Conclusion: These observations have significant value and are applicable to plastic surgeons, clinicians, anatomists and this study will provide additional information for them.

  15. Morphological and morphometric features of scaphoid bone in north eastern population, India. (United States)

    Purushothama, C; Sarda, R K; Konuri, A; Tamang, B K; Gupta, C; Murlimanju, B V


    A study was performed to analyse the morphometry and morphological variants of adult scaphoid bone in Sikkimese population of North Eastern India. The study included 100 dry human scaphoid bones. The bones which had previous signs of fracture were excluded. The morphometric parameters were measured with vernier caliper of 0.02 mm accuracy; the circumferences were measured by placing a thread around them and measuring its length. A magnifying lens was used to observe the number of foramina. From our observations, 22 (44%) of the left scaphoid were having conical shape and 28 (56%) were pyramidal in shape. On the right side, 36 (72%) had conical shape and 14 (28%) were pyramidal. All the bones had waist, except one right sided scaphoid (2%) in which the waist was absent. The scaphoid had main dorsal sulcus in 63% of cases, 29% had two dorsal sulci and 6% had Y shaped sulci. The dorsal sulcus was absent in 3 cases (1 on left side and 2 on the right side). All the scaphoids had a minimum of one foramen in the main dorsal sulcus and 92% had more than one foramen. The present study has provided the additional information on morphology and morphometry of adult human scaphoid bones in north eastern population, India. We believe that the data obtained from the present study are important for the hand surgeons and radiologists. The details obtained will also be helpful for the morphologists and clinical anatomists.

  16. Morphometric aspects of the foramen magnum and the orbit in Brazilian dry skulls

    Directory of Open Access Journals (Sweden)

    Lucas A. S. Pires


    Full Text Available Morphometric analysis of crania structures are of great significance to anatomists, forensic doctors, anthropologists, and surgeons. We performed a morphometric study regarding the foramen magnum and the bony orbit on the right side of the cranium in 77 skulls with the purpose of identifying a correlation between these measures, as they are often employed alone to identify the genre and race of a skeleton with no other remains, since the cranium is a structure that can resist fire, explosions, and mutilations. The foramen magnum receives special attention, as it is located in a region together with many strong muscles and ligaments. The measures were taken with a sliding digital caliper. Our results showed that the foramen magnum had a mean anteroposterior diameter of 34.23±2.54 mm, and the mean transverse diameter was 28.62±2.83 mm. The most common shape for the foramen magnum was oval. The mean right orbital height was 32.89±2.45 mm, and the mean right orbital breadth was 37.15±2.68 mm. There was a weak to moderate correlation between these measures. Furthermore, the foramen magnum and the orbit are regions of surgical and clinical significance, thus requiring knowledge regarding the morphometric aspects of such areas, since they can often suffer morphological changes due to a number of diseases and they undergo surgical procedures in order to treat these conditions.

  17. Ton That Tung's livers. (United States)

    Helling, Thomas S; Azoulay, Daniel


    Born in the early 20th century, the Vietnamese surgeon Ton That Tung received his medical education in French colonial Indochina at the fledgling l'Ecole de Médecine de Hanoi, the first indigenous medical school in Southeast Asia. The benefactor of a postgraduate position at the medical school, Ton That Tung subsequently obtained his surgical training at the Phù Doãn Hospital in Hanoi and concurrently developed a passion for the study of liver anatomy, pathology, and surgery. His contributions to an understanding of liver anatomy based on meticulous dissection of autopsy specimens antedated and rivaled later work by the famous Western anatomists Couinaud, Healey, Schroy, and others. Ton That Tung's contributions, however, were overshadowed by the intense national struggles of the Vietnamese to establish independent rule and self-governance from the French and by eventual alignment with eastern bloc Communist countries, thus isolating much of his work behind the "Iron Curtain" until well after the end of the Cold War. Nevertheless, Ton That Tung remains a pioneer in liver anatomy and liver surgery. His commitment to surgical science and, more importantly, to the Vietnamese people stands as a tribute to the tireless pursuit of his ideals.

  18. Skulls, brains, and memorial culture: on cerebral biographies of scientists in the nineteenth century. (United States)

    Hagner, Michael


    In this paper, I will argue that the scientific investigation of skulls and brains of geniuses went hand in hand with hagiographical celebrations of scientists. My analysis starts with late-eighteenth century anatomists and anthropologists who highlighted quantitative parameters such as the size and weight of the brain in order to explain intellectual differences between women and men and Europeans and non-Europeans, geniuses and ordinary persons. After 1800 these parameters were modified by phrenological inspections of the skull and brain. As the phrenological examination of the skulls of Immanuel Kant, Wilhelm Heinse, Arthur Schopenhauer and others shows, the anthropometrical data was interpreted in light of biographical circumstances. The same pattern of interpretation can be found in non-phrenological contexts: Reports about extraordinary brains were part of biographical sketches, mainly delivered in celebratory obituaries. It was only in this context that moral reservations about dissecting the brains of geniuses could be overcome, which led to a more systematic investigation of brains of geniuses after 1860.

  19. Sir Astley Paston Cooper (1768-1841): The man and his personality. (United States)

    Doganay, Emre


    The most acclaimed surgeon of his time, Astley Cooper, a man from Norfolk and a student of the eminent John Hunter, was an outstandingly successful surgeon. With his accomplishments in surgery and experiments in dissection he soon became a prominent figure and received recognition worldwide. At the young age of 21 he was appointed Demonstrator in Anatomy at St Thomas's Hospital in London and two years later was made Joint Lecturer in Anatomy and Surgery. With his passion for anatomy, his love for surgery and his expanding knowledge he became Surgeon to Guy's Hospital in 1800 and in the same year was elected a Fellow to the Royal Society. His attainments led him to become surgeon to three successive British monarchs as well as receiving a bestowal of Baronetcy. Through his edifying lectures, fastidious experiments and publications on anatomy and pathology he has inspired and enlightened many budding anatomists and surgeons and the principles of his teachings still prevail in practice today. © The Author(s) 2014.

  20. Preserving and sharing examples of anatomical variation and developmental anomalies via photorealistic virtual reality. (United States)

    Nieder, Gary L; Nagy, Frank; Wagner, Lynn A


    Computer graphics technology has made it possible to create photographic-quality virtual specimens from real anatomical material. One technique for doing this, QuickTime Virtual Reality (QTVR), results in virtual specimens that are easily shared on the Internet and displayed as standalone entities or incorporated into complex programs or Web sites. A compelling use of this technology is the sharing of rare specimens such as unusual variations, developmental anomalies or gross pathology. These types of specimens have traditionally been confined to anatomical museums, but could serve a much more useful existence as freely shared virtual specimens. An example presented here is a relatively rare developmental defect in the embryonic aortic arches that results in a right-sided aortic arch coursing posterior to the trachea and esophagus. In a time of ever increasing restraints on the practical side of anatomy education, an Internet-based library of human variation and other rare specimens would be a useful supplement to students' limited exposure to the human body. Since the discovery and preparation of specimens would be the rate-limiting step in producing such a collection, we propose the establishment of a center for virtual specimen creation and preservation through a cooperative effort by gross anatomists and pathologists in contributing the source material.

  1. Anatomy integration blueprint: A fourth-year musculoskeletal anatomy elective model. (United States)

    Lazarus, Michelle D; Kauffman, Gordon L; Kothari, Milind J; Mosher, Timothy J; Silvis, Matthew L; Wawrzyniak, John R; Anderson, Daniel T; Black, Kevin P


    Current undergraduate medical school curricular trends focus on both vertical integration of clinical knowledge into the traditionally basic science-dedicated curricula and increasing basic science education in the clinical years. This latter type of integration is more difficult and less reported on than the former. Here, we present an outline of a course wherein the primary learning and teaching objective is to integrate basic science anatomy knowledge with clinical education. The course was developed through collaboration by a multi-specialist course development team (composed of both basic scientists and physicians) and was founded in current adult learning theories. The course was designed to be widely applicable to multiple future specialties, using current published reports regarding the topics and clinical care areas relying heavily on anatomical knowledge regardless of specialist focus. To this end, the course focuses on the role of anatomy in the diagnosis and treatment of frequently encountered musculoskeletal conditions. Our iterative implementation and action research approach to this course development has yielded a curricular template for anatomy integration into clinical years. Key components for successful implementation of these types of courses, including content topic sequence, the faculty development team, learning approaches, and hidden curricula, were developed. We also report preliminary feedback from course stakeholders and lessons learned through the process. The purpose of this report is to enhance the current literature regarding basic science integration in the clinical years of medical school. © 2014 American Association of Anatomists.

  2. Development and evaluation of an interactive electronic laboratory manual for cooperative learning of medical histology. (United States)

    Khalil, Mohammed K; Kirkley, Debbie L; Kibble, Jonathan D


    This article describes the development of an interactive computer-based laboratory manual, created to facilitate the teaching and learning of medical histology. The overarching goal of developing the manual is to facilitate self-directed group interactivities that actively engage students during laboratory sessions. The design of the manual includes guided instruction for students to navigate virtual slides, exercises for students to monitor learning, and cases to provide clinical relevance. At the end of the laboratory activities, student groups can generate a laboratory report that may be used to provide formative feedback. The instructional value of the manual was evaluated by a questionnaire containing both closed-ended and open-ended items. Closed-ended items using a five-point Likert-scale assessed the format and navigation, instructional contents, group process, and learning process. Open-ended items assessed student's perception on the effectiveness of the manual in facilitating their learning. After implementation for two consecutive years, student evaluation of the manual was highly positive and indicated that it facilitated their learning by reinforcing and clarifying classroom sessions, improved their understanding, facilitated active and cooperative learning, and supported self-monitoring of their learning.

  3. Group in-course assessment promotes cooperative learning and increases performance. (United States)

    Pratten, Margaret K; Merrick, Deborah; Burr, Steven A


    The authors describe and evaluate a method to motivate medical students to maximize the effectiveness of dissection opportunities by using In-Course-Assessments (ICAs) to encourage teamwork. A student's final mark was derived by combining the group dissection mark, group mark for questions, and their individual question mark. An analysis of the impact of the ICA was performed by comparing end of module practical summative marks in student cohorts who had, or had not, participated in the ICAs. Summative marks were compared by two-way ANOVA followed by Dunnets test, or by repeated measures ANOVA, as appropriate. A cohort of medical students was selected that had experienced both practical classes without (year one) and with the new ICA structure (year two). Comparison of summative year one and year two marks illustrated an increased improvement in year two performance in this cohort. A significant increase was also noted when comparing this cohort with five preceding year two cohorts who had not experienced the ICAs (P learning resources in an active, team-based, cooperative learning environment. © 2013 American Association of Anatomists.

    Lesić, Aleksandar; Draganić-Gajić, Saveta; Bumbasirević, Marko


    Dr. Niko Miljanic anatomist and surgeon, ordinary professor of the Medical Faculty in Belgrade, had been managing there the anatomy teaching during the period 1920-1934, then held lectures on surgery propedeutics since 1935 till 1947, when being a principled person with the moral sense for the profession and his task as an university professor, after his action as a member of the committee for Election of the Medical Faculty Teachers, he was relieved in 1954 year from the faculty. Professor Miljanic was the author of our first textbooks of anatomy, a monography on asepsis as well as a lot of scientific articles on anatomy and surgery in different journals at home and abroad. As a French ex-pupil he was elected president of the French ex-pupils Association and the founder of the bilingual Serbian-French journal "Anali medicine i hirurgije" (Annals of Medicine and Surgery"), published 1927-1934. In 1930, together with the King Alexander I, he uncover in Belgrade Kalemegdan Park the Monument of the Gratitude to France. He fought in both Balcanic and both World wars. Professor Miljanic was a member of the French Academy of Surgeons and was decorated with the order of the Legion of Honour.

  5. The use of museum specimens with high-throughput DNA sequencers. (United States)

    Burrell, Andrew S; Disotell, Todd R; Bergey, Christina M


    Natural history collections have long been used by morphologists, anatomists, and taxonomists to probe the evolutionary process and describe biological diversity. These biological archives also offer great opportunities for genetic research in taxonomy, conservation, systematics, and population biology. They allow assays of past populations, including those of extinct species, giving context to present patterns of genetic variation and direct measures of evolutionary processes. Despite this potential, museum specimens are difficult to work with because natural postmortem processes and preservation methods fragment and damage DNA. These problems have restricted geneticists' ability to use natural history collections primarily by limiting how much of the genome can be surveyed. Recent advances in DNA sequencing technology, however, have radically changed this, making truly genomic studies from museum specimens possible. We review the opportunities and drawbacks of the use of museum specimens, and suggest how to best execute projects when incorporating such samples. Several high-throughput (HT) sequencing methodologies, including whole genome shotgun sequencing, sequence capture, and restriction digests (demonstrated here), can be used with archived biomaterials.

  6. An enriched multimedia eBook application to facilitate learning of anatomy. (United States)

    Stirling, Allan; Birt, James


    This pilot study compared the use of an enriched multimedia eBook with traditional methods for teaching the gross anatomy of the heart and great vessels. Seventy-one first-year students from an Australian medical school participated in the study. Students' abilities were examined by pretest, intervention, and post-test measurements. Perceptions and attitudes toward eBook technology were examined by survey questions. Results indicated a strongly positive user experience coupled with increased marks; however, there were no statistically significant results for the eBook method of delivery alone outperforming the traditional anatomy practical session. Results did show a statistically significant difference in the final marks achieved based on the sequencing of the learning modalities. With initial interaction with the multimedia content followed by active experimentation in the anatomy lab, students' performance was improved in the final test. Obtained data support the role of eBook technology in modern anatomy curriculum being a useful adjunct to traditional methods. Further study is needed to investigate the importance of sequencing of teaching interventions. © 2013 American Association of Anatomists.

  7. Embodiments of will. (United States)

    Nutton, Vivian


    From the fifth century BCE onwards, Greek doctors and philosophers debated the ways in which the will could be translated into physical action. Aristotle and his followers believed that the heart was the controlling organ, working through sinews. Later anatomists, first in Alexandria in Egypt and later in the Roman world, continued to speculate for several centuries. Galen (129-ca. 216) established a new medical paradigm, insisting on the primacy of the brain mediating largely through nerves. The Aristotelian and Galenic theories continued to be debated in the Greek and Islamic worlds, and, in new Latin translations, in the later Western medieval universities. These debates were largely conducted without recourse to experiment. Even after Mondino de' Liuzzi had introduced the dissection of a corpse in his teaching at Bologna around 1318, the battle of the texts continued into the 17th century. Although Michael Frampton ranges widely in Embodiments of Will, he has left out much, including a recently (re)discovered treatise by Galen that considers in detail the relationship between the brain, the nerves, and bodily movements.

  8. Explorable three-dimensional digital model of the female pelvis, pelvic contents, and perineum for anatomical education. (United States)

    Sergovich, Aimée; Johnson, Marjorie; Wilson, Timothy D


    The anatomy of the pelvis is complex, multilayered, and its three-dimensional organization is conceptually difficult for students to grasp. The aim of this project was to create an explorable and projectable stereoscopic, three-dimensional (3D) model of the female pelvis and pelvic contents for anatomical education. The model was created using cryosection images obtained from the Visible Human Project, in conjunction with a general-purpose three-dimensional segmentation and surface-rendering program. Anatomical areas of interest were identified and labeled on consecutive images. Each 2D slice was reassembled, forming a three-dimensional model. The model includes the pelvic girdle, organs of the pelvic cavity, surrounding musculature, the perineum, neurovascular structures, and the peritoneum. Each structure can be controlled separately (e.g. added, subtracted, made transparent) to reveal organization and/or relationships between structures. The model can be manipulated and/or projected stereoscopically to visualize structures and relationships from different angles with excellent spatial perception. Because of its ease of use and versatility, we expect this model may provide a powerful teaching tool for learning in the classroom or in the laboratory. (c) 2010 American Association of Anatomists.

  9. Development of an interactive anatomical three-dimensional eye model. (United States)

    Allen, Lauren K; Bhattacharyya, Siddhartha; Wilson, Timothy D


    The discrete anatomy of the eye's intricate oculomotor system is conceptually difficult for novice students to grasp. This is problematic given that this group of muscles represents one of the most common sites of clinical intervention in the treatment of ocular motility disorders and other eye disorders. This project was designed to develop a digital, interactive, three-dimensional (3D) model of the muscles and cranial nerves of the oculomotor system. Development of the 3D model utilized data from the Visible Human Project (VHP) dataset that was refined using multiple forms of 3D software. The model was then paired with a virtual user interface in order to create a novel 3D learning tool for the human oculomotor system. Development of the virtual eye model was done while attempting to adhere to the principles of cognitive load theory (CLT) and the reduction of extraneous load in particular. The detailed approach, digital tools employed, and the CLT guidelines are described herein. © 2014 American Association of Anatomists.

  10. A multiscale imaging and modelling dataset of the human inner ear. (United States)

    Understanding the human inner ear anatomy and its internal structures is paramount to advance hearing implant technology. While the emergence of imaging devices allowed researchers to improve understanding of intracochlear structures, the difficulties to collect appropriate data has resulted in studies conducted with few samples. To assist the cochlear research community, a large collection of human temporal bone images is being made available. This data descriptor, therefore, describes a rich set of image volumes acquired using cone beam computed tomography and micro-CT modalities, accompanied by manual delineations of the cochlea and sub-compartments, a statistical shape model encoding its anatomical variability, and data for electrode insertion and electrical simulations. This data makes an important asset for future studies in need of high-resolution data and related statistical data objects of the cochlea used to leverage scientific hypotheses. It is of relevance to anatomists, audiologists, computer scientists in the different domains of image analysis, computer simulations, imaging formation, and for biomedical engineers designing new strategies for cochlear implantations, electrode design, and others.

  11. [New pedagogic methods in anatomy: experience at Cambridge University]. (United States)

    Kluchova, D


    The expansion of knowledge in basic medical sciences is not linked to the time assigned for the teaching of anatomy to medical undergraduates. The question of "basic knowledge" in teaching anatomy during medical training arises as a need for education of future clinical doctors. Nowadays, two extreme views in teaching anatomy can be recognized: one adopted some pure anatomists who feel their existence threatened even by the idea of any reduction in their field, and one by some morphologists exclusively interested in cellular biology, who consider that classical anatomy is of no interest, since it has been exhausted as a field for research. An intermediate position is taken by some clinicians, who maintain that anatomy is indispensable but seek a severe reduction in the content to what they consider to be necessary. The above mentioned need for clinicians was reflected in recommendations of Education Committee of the General Medical Council (GMC) which in short, could be characterized by: the substantial reduction of factual information, the increase of student learning and the emphasis of clinically applied anatomy with its integration to the general medical education. GMC delegated the Department of Anatomy at the University of Cambridge by the developing of the new anatomy course. This new course was for the first time introduced in school year 1998-1999. In this study are presented ways and methods of undergraduate anatomy teaching at the University of Cambridge. These educational principles could serve as a model for teaching anatomy during its transformation in other medical faculties.

  12. Can a teaching assistant experience in a surgical anatomy course influence the learning curve for nontechnical skill development for surgical residents? (United States)

    Heidenreich, Mark J; Musonza, Tashinga; Pawlina, Wojciech; Lachman, Nirusha


    The foundation upon which surgical residents are trained to work comprises more than just critical cognitive, clinical, and technical skill. In an environment where the synchronous application of expertise is vital to patient outcomes, the expectation for optimal functioning within a multidisciplinary team is extremely high. Studies have shown that for most residents, one of the most difficult milestones in the path to achieving professional expertise in a surgical career is overcoming the learning curve. This view point commentary provides a reflection from the two senior medical students who have participated in the Student-as-Teacher program developed by the Department of Anatomy at Mayo Clinic, designed to prepare students for their teaching assistant (TA) role in anatomy courses. Both students participated as TAs in a six week surgical anatomy course for surgical first assistant students offered by the School of Health Sciences at Mayo Clinic. Development of teaching skills, nontechnical leadership, communication, and assessment skills, are discussed in relation to their benefits in preparing senior medical students for surgical residency. © 2015 American Association of Anatomists.

  13. Demystifying the Millennial student: a reassessment in measures of character and engagement in professional education. (United States)

    DiLullo, Camille; McGee, Patricia; Kriebel, Richard M


    The characteristic profile of Millennial Generation students, driving many educational reforms, can be challenged by research in a number of fields including cognition, learning style, neurology, and psychology. This evidence suggests that the current aggregate view of the Millennial student may be less than accurate. Statistics show that Millennial students are considerably diverse in backgrounds, personalities, and learning styles. Data are presented regarding technological predilection, multitasking, reading, critical thinking, professional behaviors, and learning styles, which indicate that students in the Millennial Generation may not be as homogenous in fundamental learning strategies and attitudes as is regularly proposed. Although their common character traits have implications for instruction, no available evidence demonstrates that these traits impact their fundamental process of learning. Many curricular strategies have been implemented to address alleged changes in the manner by which Millennial students learn. None has clearly shown superior outcomes in academic accomplishments or developing expertise for graduating students and concerns persist related to the successful engagement of Millennial students in the process of learning. Four factors for consideration in general curricular design are proposed to address student engagement and optimal knowledge acquisition for 21st century learners.

  15. Anatomy education for the YouTube generation. (United States)

    Barry, Denis S; Marzouk, Fadi; Chulak-Oglu, Kyrylo; Bennett, Deirdre; Tierney, Paul; O'Keeffe, Gerard W


    Anatomy remains a cornerstone of medical education despite challenges that have seen a significant reduction in contact hours over recent decades; however, the rise of the "YouTube Generation" or "Generation Connected" (Gen C), offers new possibilities for anatomy education. Gen C, which consists of 80% Millennials, actively interact with social media and integrate it into their education experience. Most are willing to merge their online presence with their degree programs by engaging with course materials and sharing their knowledge freely using these platforms. This integration of social media into undergraduate learning, and the attitudes and mindset of Gen C, who routinely creates and publishes blogs, podcasts, and videos online, has changed traditional learning approaches and the student/teacher relationship. To gauge this, second year undergraduate medical and radiation therapy students (n = 73) were surveyed regarding their use of online social media in relation to anatomy learning. The vast majority of students had employed web-based platforms to source information with 78% using YouTube as their primary source of anatomy-related video clips. These findings suggest that the academic anatomy community may find value in the integration of social media into blended learning approaches in anatomy programs. This will ensure continued connection with the YouTube generation of students while also allowing for academic and ethical oversight regarding the use of online video clips whose provenance may not otherwise be known. © 2015 American Association of Anatomists.

  16. [Gender equality activity in the Bioimaging Society]. (United States)

    Suzaki, Etsuko


    Gender equality activity in the Bioimaging Society was initiated in 2005 when it joined the Japan Inter-Society Liaison Association Committee for Promoting Equal Participation of Men and Women in Science and Engineering (EPMEWSE). The Gender Equality Committee of the Bioimaging Society is acting on this issue by following the policy of the EPMEWSE, and has also been planning and conducting lectures at annual meetings of the society to gain the understanding, consents, and cooperation of the members of the society to become conscious of gender equality. Women's participation in the society has been promoted through the activities of the Gender Equality Committee, and the number of women officers in the society has since increased from two women out of 40 members in 2005 to five out of 44 in 2013. The activities of the Gender Equality Committee of the Japanese Association of Anatomists (JAA) have just started. There are more than 400 women belonging to the JAA. When these women members join together and collaborate, women's participation in the JAA will increase.

  17. [The present status and attempts toward the achievement of gender equality in the JAA]. (United States)

    Senba, Emiko


    The proportion of female members in The Japanese Association of Anatomists (JAA) is 18% with the proportion of female members higher among the young generation (20-30 Y.O.; 34.8%, 30-40 Y.O.; 26.8%). However, the number of female members in the Board of Directors has been zero or one (0 or 6%) for many years. More than two female members are necessary on the Board to promote the diversity in the management of the JAA. The numbers of female members in other committees has shown gradual increase in recent years. A substantial increase in female faculty members including professors in each university and school will support the future development of the anatomical research field and the association. We have made the first great step by setting up the committee on promotion of gender equality in JAA in March, 2011. In the next year, JAA became a member of Japan Inter-Society Liaison Association Committee for Promoting Equal Participation of Men and Women in Science and Engineering (EPMEWSE). Our committee's activity includes holding workshops and seminars at the annual meetings to promote gender equality in the research field and to encourage mutual support and friendship, not only among women members but also among all members.

  18. Gross anatomy videos: student satisfaction, usage, and effect on student performance in a condensed curriculum. (United States)

    Topping, Daniel B


    Anatomy educators are being tasked with delivering the same quantity and quality of material in the face of fewer classroom and laboratory hours. As a result they have turned to computer-aided instruction (CAI) to supplement and augment curriculum delivery. Research on the satisfaction and use of anatomy videos, a form of CAI, on examination performance continues to grow. The purpose of this study was to describe the usage and effect on examination scores of a series of locally produced anatomy videos after an 11% curriculum reduction. First-year medical students (n = 40) were given access to the videos and the prior year's students (n = 40) were used as historical controls. There was no significant difference in demographics between the two groups. The survey response rate was 85% (n = 34) in the experimental group. The students found the videos to be highly satisfying (median = 5 on a five-point Likert scale, interquartile range = 1) and used them on average 1.55 times/week (SD ± 0.77). Availability of the videos did have a statistically significant effect (4% improvement) on the final laboratory examination (p = 0.039). This suggests that the videos were a well-received form of CAI that may be useful in bridging the gap created by a reduction in gross anatomy course contact hours. © 2013 American Association of Anatomists.

  19. Dissection videos do not improve anatomy examination scores. (United States)

    Mahmud, Waqas; Hyder, Omar; Butt, Jamaal; Aftab, Arsalan


    In this quasi-experimental study, we describe the effect of showing dissection videos on first-year medical students' performance in terms of test scores during a gross anatomy course. We also surveyed students' perception regarding the showing of dissection videos. Two hundred eighty-seven first-year medical students at Rawalpindi Medical College in Pakistan, divided into two groups, dissected one limb in first term and switched over to the other limb in the second term. During the second term, instruction was supplemented by dissection videos. Second-term anatomy examination marks were compared with first-term scores and with results from first-year medical students in previous years. Multiple linear regression analysis was performed, with term scores (continuous, 0-200) as the dependent variable. Students shown dissection videos scored 1.26 marks higher than those not shown. The relationship was not statistically significant (95% CI: -1.11, 3.70; P = 0.314). Ninety-three percent of students favored regular inclusion of dissection videos in curriculum, and 50% termed it the best source for learning gross anatomy. Seventy-six percent of students did not perform regular cadaver dissection. The most frequent reason cited for not performing regular dissection was high student-cadaver ratio. Dissection videos did not improve performance on final examination scores; however, students favored their use. Copyright © 2011 American Association of Anatomists.

  20. Study skills in anatomy and physiology: Is there a difference? (United States)

    Husmann, Polly R; Barger, J Bradley; Schutte, Audra F


    Many factors influence the way individual students study, including but not limited to: previous coursework, attitudes toward the class (motivation, intimidation, risk, etc.), metacognition, and work schedules. However, little of this research has involved medical students. The present article asks the question, "Do individual medical students study differently for different classes?" Study skills surveys were given to United States medical students at an allopathic medical school and an osteopathic medical school. Students were surveyed near the end of their first year gross anatomy course and again near the end of their first year physiology course. Survey items included Likert scale and open-ended questions about study habits and basic demographic information. The survey responses were correlated with each student's final grade percentages in the courses. Analysis revealed that the four most common study habits were reviewing lecture notes, taking practice examinations, completing learning exercises, and making drawings and diagrams. The two surveys (anatomy and physiology) from each individual were also compared to see if students reported different study habits in anatomy versus physiology. A negative correlation was found between changing study habits between courses and final anatomy grade percentages. Additional analyses suggest that those students who do change their study habits between courses are increasing the number of study strategies that they attempt. This increase in the number of study strategies attempted may not allow the student to reach the same depth of understanding as their colleagues who utilize fewer strategies. © 2015 American Association of Anatomists.

  1. Brodmann area 12: an historical puzzle relevant to FTLD. (United States)

    Kawamura, M; Miller, M W; Ichikawa, H; Ishihara, K; Sugimoto, A


    Brodmann brain maps, assembled in 1909, are still in use, but understanding of their animal-human homology is uncertain. Furthermore, in 1909, Brodmann did not identify human area 12 (BA12), a location now important to understanding of frontotemporal lobar degeneration (FTLD). We re-examined Brodmann's areas, both animal and human, in his 1909 monograph and other literature, both historical and contemporary, and projected BA12 onto the medial surface of a fixed human brain to show its location. We found Brodmann did identify human BA12 in later maps (1910 and 1914), but that his brain areas, contrary to his own aims as a comparative anatomist, are now used as physiologic loci in human brain. Because of its current link with frontotemporal dementia, BA12's transition from animal (1909) to human (1910 and 1914) is not only an historical puzzle. It impacts how Brodmann's areas, based on comparative animal-human cytoarchitecture, are widely used in current research as functional loci in human brain.

  2. Authoritative Images. The Kiwi and the Transactions of the Zoological Society of London. (United States)

    Canadelli, Elena


    The first exemplar of a kiwi, the wingless bird of New Zealand, arrived in the form of a lifeless specimen in Europe in 1812. A debate was sparked over the appearance and nature of this strange creature and indeed whether it actually existed. In 1833 the Transactions of the Zoological Society of London entered the debate and the illustrations published in this journal contributed greatly to the acceptance and further study of the kiwi. Some of the most eminent British zoologists and anatomists of the time were involved, from William Yarrell to Richard Owen, and from John Gould to Abraham Dee Bartlett. This crucial period in the discussion, which would extend over two decades and would only be brought to a close with the arrival of the first living specimen in the London Zoological Garden in 1851, will be analyzed based on a detailed examination of the reports published in the Transactions and other journals. This essay will show how images of the bird were produced and used by zoologists during different stages in the early research on the bird and how these figures circulated inside and outside the zoologists' community.

  3. The role of student surgical interest groups and surgical Olympiads in anatomical and surgical undergraduate training in Russia. (United States)

    Dydykin, Sergey; Kapitonova, Marina


    Traditional department-based surgical interest groups in Russian medical schools are useful tools for student-based selection of specialty training. They also form a nucleus for initiating research activities among undergraduate students. In Russia, the Departments of Topographical Anatomy and Operative Surgery play an important role in initiating student-led research and providing learners with advanced, practical surgical skills. In tandem with department-led activities, student surgical interest groups prepare learners through surgical competitions, known as "Surgical Olympiads," which have been conducted in many Russian centers on a regular basis since 1988. Surgical Olympiads stimulate student interest in the development of surgical skills before graduation and encourage students to choose surgery as their postgraduate specialty. Many of the participants in these surgical Olympiads have become highly qualified specialists in general surgery, orthopedic surgery, neurosurgery, urology, gynecology, and emergency medicine. The present article emphasizes the role of student interest groups and surgical Olympiads in clinical anatomical and surgical undergraduate training in Russia. © 2015 American Association of Anatomists.

  4. The platypus in Edinburgh: Robert Jameson, Robert Knox and the place of the Ornithorhynchus in nature, 1821-24. (United States)

    Jenkins, Bill


    The duck-billed platypus, or Ornithorhynchus, was the subject of an intense debate among natural historians in the late eighteenth and early nineteenth centuries. Its paradoxical mixture of mammalian, avian and reptilian characteristics made it something of a taxonomic conundrum. In the early 1820s Robert Jameson (1774-1854), the professor of natural history at the University of Edinburgh and the curator of the University's natural history museum, was able to acquire three valuable specimens of this species. He passed one of these on to the anatomist Robert Knox (1791-1862), who dissected the animal and presented his results in a series of papers to the Wernerian Natural History Society, which later published them in its Memoirs. This paper takes Jameson's platypus as a case study on how natural history specimens were used to create and contest knowledge of the natural world in the early nineteenth century, at a time when interpretations of the relationships between animal taxa were in a state of flux. It shows how Jameson used his possession of this interesting specimen to provide a valuable opportunity for his protégé Knox while also helping to consolidate his own position as a key figure in early nineteenth-century natural history.

  6. Team-based learning in the gross anatomy laboratory improves academic performance and students' attitudes toward teamwork. (United States)

    Huitt, Tiffany W; Killins, Anita; Brooks, William S


    As the healthcare climate shifts toward increased interdisciplinary patient care, it is essential that students become accomplished at group problem solving and develop positive attitudes toward teamwork. Team-based learning (TBL) has become a popular approach to medical education because of its ability to promote active learning, problem-solving skills, communication, and teamwork. However, its documented use in the laboratory setting and physical therapy education is limited. We used TBL as a substitute for one-third of cadaveric dissections in the gross anatomy laboratories at two Doctor of Physical Therapy programs to study its effect on both students' perceptions and academic performance. We surveyed students at the beginning and completion of their anatomy course as well as students who had previously completed a traditional anatomy course to measure the impact of TBL on students' perceptions of teamwork. We found that the inclusion of TBL in the anatomy laboratory improves students' attitudes toward working with peers (P students had significantly lower attitudes toward teamwork (P students revealed that students who participated in TBL scored significantly higher on their first anatomy practical examination and on their head/neck written examination (P improving both students' grades and perceptions of teamwork. © 2014 American Association of Anatomists.

  7. Students helping students: Evaluating a pilot program of peer teaching for an undergraduate course in human anatomy. (United States)

    Bruno, Paul A; Love Green, Jennifer K; Illerbrun, Sara L; Holness, Duncan A; Illerbrun, Samantha J; Haus, Kara A; Poirier, Sylvianne M; Sveinson, Katherine L


    The educational literature generally suggests that supplemental instruction (SI) is effective in improving academic performance in traditionally difficult courses. A pilot program of peer teaching based on the SI model was implemented for an undergraduate course in human anatomy. Students in the course were stratified into three groups based on the number of peer teaching sessions they attended: nonattendees (0 sessions), infrequently attended (1-3 sessions), and frequently attended (≥ 4 sessions). After controlling for academic preparedness [i.e., admission grade point average (AGPA)] using an analysis of covariance, the final grades of frequent attendees were significantly higher than those of nonattendees (P = 0.025) and infrequent attendees (P = 0.015). A multiple regression analysis was performed to estimate the relative independent contribution of several variables in predicting the final grade. The results suggest that frequent attendance (β = 0.245, P = 0.007) and AGPA (β = 0.555, P student (β = -0.217, P = 0.006) was a significant negative predictor. Collectively, these results suggest that attending a certain number of sessions may be required to gain a noticeable benefit from the program, and that first-year students (particularly those with a lower level of academic preparedness) would likely stand to benefit from maximally using the program. End-of-semester surveys and reports indicate that the program had several additional benefits, both to the students taking the course and to the students who served as program leaders.

  8. The beginnings of dermatopathology and dermatologic microbiology in Spain. (United States)

    del Río, E


    Crisóstomo Martínez from Valencia was a pioneering microscopist in 17th-century Europe. The first microscopic representations of skin in Spain appeared in an 18th-century work by Martín Martínez. Microbiology and histopathology progressed considerably in the late 19th century thanks to anatomists like Maestre de San Juan and surgeons like Federico Rubio Galí. The first Spanish pathologist to specialize in dermatology was Antonio Mendoza, a colleague of José Eugenio de Olavide at the Hospital San Juan de Dios in Madrid. Claudio Sala and Juan de Azúa also made significant contributions, including the description of pseudoepithelioma. Several disciples of Santiago Ramón y Cajal and Jorge FranciscoTello, such as Lorenzo Ruiz de Arcaute and Guillermo de la Rosa King, consolidated the dermatology laboratory, but the Civil War sent many into exile or deprived them of their professional status. Juan Rubió in Barcelona and Julio Rodríguez Puchol in Madrid were the immediate predecessors of today's dermatopathologists. Copyright © 2012 Elsevier España, S.L. y AEDV. All rights reserved.

  9. Size-dependent variation in plant form. (United States)

    Niklas, Karl J; Cobb, Edward D


    The study of organic form has a long and distinguished history going at least as far back as Aristotle's Historia Anima¯lium, wherein he identified five basic biological processes that define the forms of animals (metabolism, temperature regulation, information processing, embryo development, and inheritance). Unfortunately, all of Aristotle's writings about plant forms are lost. We know of them only indirectly from his student Theophrastus's companion books, collectively called Historia Plantarum, wherein plant forms are categorized into annual herbs, herbaceous perennials, shrubs, and trees. The study of plant forms did not truly begin until the romantic poet and naturalist Goethe proposed the concept of a hypothetical 'Plant Archetype', declared "Alles ist Blatt", and first coined the word morphologie, which inspired the French anatomist Cuvier (who established the field of comparative morphology), the English naturalist Darwin (who saw his theory of evolution reinforced by it), and the Scottish mathematician D'Arcy Thompson (who attempted to quantify it).

  10. The perception of place and the 'origins of handedness' debate: towards a cognitive cartography of science in late-Victorian Dublin. (United States)

    O'Sullivan, Tanya


    In 1884, a medical paper entitled 'Consideration of the Structural and Acquisitional Elements in Dextral Pre-Eminence' penned by the Dublin physician George Sigerson, appeared in the Proceedings of the Royal Irish Academy. A number of years later, the Journal of the Anthropological Institute of Great Britain and Ireland presented a similar piece by Dublin anatomist Daniel John Cunningham, on the topic of 'Right-Handedness and Left-Brainedness'. For the late nineteenth-century scientific community, these articles represented two Dublin-based contributions to a long-running and wide-ranging debate on the origins of handedness. However, by building on the geographical premise that scientific knowledge bears the imprint of its location and that place matters in the way scientific claims come to be sanctioned, this paper probes, not merely an encounter with evolutionary science in the less well explored domain of fin de siècle Dublin, but more crucially, how these local reviews of manual dexterity were in part shaped by the scientists' differing perceptions of their city. By attending to the lives of Sigerson and Cunningham and focusing on the interplay between life-space, city-space and science, it underscores the critical role of place and space in the reception, circulation and mobilisation of scientific knowledge in the city.

  11. The superficial venous system of the lower extremity: new nomenclature. (United States)

    Kachlik, D; Pechacek, V; Baca, V; Musil, V


    The phlebology in the area of lower limbs is the only medical field in which the terminological needs of clinicians were met. Ten years ago, the latest revision of the Latin anatomical nomenclature, Terminologia Anatomica (TA), was issued. But almost none of the chapters reflected the clinicians' need to be a relevant theoretical base for correct diagnostics and appropriate treatment. In 2001, during the 14th World Congress of the International Union of Phlebology, a consensus document (under the auspices of Federative International Committee on Anatomical Terminology and International Federation of Associations of Anatomists) was laid to expand the nomenclature of the lower extremity venous system. Some terms have been changed and several new have been added, corresponding to their clinical significance and anatomical positions. Sixteen new terms have been added in both Latin and English languages in the chapter concerning the superficial veins of the lower limb. This consensus document will be incorporated into the next version of the TA. The international anatomical nomenclature serves as a communication base for research, diagnostic, therapy and information exchange in phlebological sciences.

  12. [Terminologia anatomica: a new reference work for anatomy]. (United States)

    Drukker, J; Walvoort, H C


    The Nomina anatomica (6th edition in 1989) was the standard anatomical nomenclature until recently. It has been succeeded by the Terminologia anatomica (TA) by resolution of the International Federation of Associations of Anatomists in 1999. By now the TA has been published as a book and on cd-rom. The objective of the TA is to further uniformize the anatomical terminology, also internationally, and especially to democratize it, i.e. to ensure that it accommodates the needs of clinicians and medical scientists. The number of anatomical terms listed has grown to more than 7500. The increase is caused mainly by the insertion of clinical anatomical and neuro-anatomical names. A number of incorrect or misleading terms have been replaced. Each Latin term has a unique code number and is supplied with an English equivalent (International anatomical terminology; IAT) the spelling of which in either UK English or American English is considered equally correct. Based on the TA every language can formulate its own anatomical nomenclature. The nomenclature is presented per system or organ tract. An alphabetic index follows TA as well as the English IAT list. The use of eponyms is discouraged, but a list of well-known ones is appended to facilitate accessibility of older literature. Relevant suggestions about amendments are eagerly awaited and a broad basis of endorsement among the medical scientific world is hoped for. This journal will adopt the TA/IAT from now on as the work of reference regarding anatomical terms.

  13. Reevaluation of the superior radial collateral artery in the human upper arm. (United States)

    Ichimura, Koichiro; Kinose, Shota; Kawasaki, Yuto; Kato, Kota; Sakai, Tatsuo


    The superior radial collateral artery (SRCA) was described in well-established anatomy textbooks published in the 1800s. According to those textbooks, the SRCA originates from the brachial artery, passes transversely between the coracobrachialis and the humerus, and distributes to the most distal portion of the deltoid. The SRCA is not listed in the international standard on anatomical terminology, Terminologia Anatomica, or in modern anatomy textbooks. In the present study, we reevaluated the anatomical features of the SRCA by cadaveric dissection. We found that two kinds of SRCAs were consistently present in the upper arm. One was similar to the previous descriptions of the SRCA in terms of origin and course, but the distribution was somewhat different. The other was similar to the previous descriptions in terms of the distribution, although it differed in origin and course. The discrepancy between the description of the SRCA in classical textbooks and the actual morphologies of the SRCA presumably prompted previous anatomists to question the existence of the SRCA, resulting in its absence from anatomical textbooks after a particular time point.

  14. Total Mesorectal Excision, an erroneous anatomical term for the gold standard in rectal cancer treatment. (United States)

    Rodríguez-Luna, María Rita; Guarneros-Zárate, Joaquín E; Tueme-Izaguirre, Jorge


    In 1986 Professor R J Heald published in The Lancet his new technique which he called Total Mesorectal Excision; today this is the gold standard for the surgical management of rectal cancer. In Total Mesorectal Excision (TME), the mesorectum is the term used to describe all the peri-rectal connective tissue including the posterior sheath of the endopelvic fascia containing the peri-rectal neurovascular structures. However, the mesenterium is a defined structure composed of a double layer of peritoneum which does not include the endopelvic fascia and the lateral rectal stalks, so these should not be included in the term 'mesorectum'. In our globalized medical culture it is important to use anatomic terms approved by the International Federation of Associations of Anatomists, as contained in the Terminologia Anatomica produced by the Federative International Programme for Anatomical Terminology (FIPAT). The term mesorectum is not listed in the Terminologia Anatomica. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

  15. Designing anatomy program in modern medical curriculum: matter of balance. (United States)

    Grković, Ivica; Marinović Guić, Maja; Kosta, Vana; Poljicanin, Ana; Carić, Ana; Vilović, Katarina


    To evaluate the structure of the anatomy program in the first year medical curriculum of University of Split School of Medicine by comparing it with the recommendations by the Educational Affairs Committee of the American Association of Clinical Anatomists (AACA) and the Terminologia Anatomica (TA); we also quantitatively evaluated the organization of teaching material in contemporary topographical anatomy textbooks and matched them with the AACA recommendations, TA, and the curriculum of the anatomy course taught at Medical School in Split, Croatia. TA, official recommendations of the AACA, 6 contemporary anatomy textbooks, and the structure of the anatomy course were analyzed for the proportion of the terms or text devoted to standard topographical regions of the body. The findings were correlated using Spearman rho test. The curriculum outline correlated both with the AACA recommendations (Spearman rho=0.83, P=0.015) and TA (Spearman rho=0.73, P=0.046). Textbooks contained 8 distinct sections, 7 allocated to topographic anatomy regions and 1 to general anatomy concepts and principles. The structure of all textbooks correlated significantly with the course curriculum. However, 4 out of 6 textbooks did not correlate with TA and only a single textbook showed significant correlation with the AACA recommendations. Anatomy textbooks vary in the amount of text dedicated to different parts of topographical anatomy and are not quite concordant with curriculum recommendations and standard anatomical terminology. Planning the structure of an anatomy course should not be based on a single book or recommendation but on evidence.

  16. Making anatomic terminology of the prostate and contiguous structures clinically useful: historical review and suggestions for revision in the 21st century. (United States)

    Myers, Robert P; Cheville, John C; Pawlina, Wojciech


    Herein we review nomenclature of the prostate and contiguous structures in each of the 10 official publications from the 1895 [Basel] Nomina Anatomica to the 1998 Terminologia Anatomica. We then compare existing clinical terminology with official terminology endorsed by anatomists over the years with a goal to modernize official terminology. Problematic terms, namely, lobes and lobuli, fascia versus capsule, Denonvilliers' fascia, and transition versus periurethral zone, are addressed. The idea of recognizing prostate arteries, veins, nerves, and neurovascular bundles is introduced. Prostatic and membranous urethras and the closely related external urethral sphincter are covered. We believe urogenital hiatus should also be called anterior levator hiatus. Trapezoid zone should be discarded in future editions of nomenclature. Our recommended changes are supported by a series of pertinent photographs of gross and whole mount histologic specimens and magnetic resonance images. Finally, we provide a new table of terms for the prostate with recommended amendments and deletions to existing official nomenclature as contained in the 1998 Terminologia Anatomica.

  17. The venous system of the pelvis: new nomenclature. (United States)

    Kachlik, D; Pechacek, V; Musil, V; Baca, V


    The clinical venous anatomy of the pelvis and its veins featured a break-through during the past few years. Not only the diagnostic and therapeutical methods but also the knowledge of the functional anatomy and nomenclatures of the veins underwent substantial changes. Eleven years ago, the most recent revision of the Latin anatomical nomenclature, Terminologia Anatomica (TA, 1998) was issued. In 2004, during the 21st World Congress of the International Union of Angiology, a consensus document (under the auspices of Federative International Committee on Anatomical Terminology and International Federation of Associations of Anatomists), reflecting phlebologists' requests for new terms and replacing several insufficient ones, was accepted. Six new terms were added in both Latin and English languages in the chapter concerning the veins of the pelvis. Eponyms are not considered equal synonyms and moreover only one of them was recommended for general use. Detailed anatomy of the veins of the pelvis is discussed. This consensus document will be incorporated in the next version of the Teminologia Anatomica.

  18. [Ten years after the latest revision International Anatomical Terminology]. (United States)

    Kachlík, D; Bozdechová, I; Cech, P; Musil, V; Báca, V


    Ten years ago, the latest revision of the Latin anatomical nomenclature was approved and published as Terminologia Anatomica (International Anatomical Terminology), and is acknowledged by the organization uniting national anatomical societies--International Federation of Associations of Anatomists. The authors concentrate on new terms included in the nomenclature and on the linguistic changes of terminology. The most frequent errors done by medical specialists in the usage of the Latin anatomical terminology are emphasized and the situation of eponyms in contemporary anatomy is discussed in detail as well. The last version of the nomenclature makes its way very slowly in the professional community and it is necessary to refer to positive changes and advantages it has brought. The usage of this Latin anatomical nomenclature version is suggested by the International Federation to follow in theoretical and clinical fields of medicine. The authors of the article strongly recommend using the recent revision of the Latin anatomical nomenclature both in the oral and written forms, when educating and publishing.

  19. Medical students' understanding of the concept of a soul. (United States)

    Martyn, Helen; Barrett, Anthony; Nicholson, Helen D


    The concept of a soul has been discussed throughout religious, philosophical, and scientific circles, yet no definitive description exists. Recent interviews with medical students during the production of a documentary film identified that many believed in the concept of a soul. This study explores students' understanding of the concept of a soul. The 2011 cohort of second-year medical students at the University of Otago in Dunedin, New Zealand were invited to participate in an online survey with a free text response asking students to describe their understanding of the soul. The descriptions of the soul included the soul as a "spirit" or "life force" and some described the soul as giving a person their "values" and "personality." Students discussed the location of a soul with most stating that the soul was not attached to the body, but others mentioned the heart or the brain as the seat of the soul. A common theme related to the mortality of the soul emerged, with most believing that the soul left the body at death. Some students' concept of a soul was related to their religious beliefs, while others who did not believe in the concept of a soul described it as a "myth" used to bring comfort at the time of death. Medical students have varied opinions on the concept and importance of the soul. It is important to recognize the diversity of views when exploring the process of death and spirituality with medical students. © 2013 American Association of Anatomists.

  20. Variations in brachial plexus and the relationship of median nerve with the axillary artery: a case report

    Directory of Open Access Journals (Sweden)

    Rao Vani


    Full Text Available Abstract Background Brachial Plexus innervates the upper limb. As it is the point of formation of many nerves, variations are common. Knowledge of these is important to anatomists, radiologists, anesthesiologists and surgeons. The presence of anatomical variations of the peripheral nervous system is often used to explain unexpected clinical signs and symptoms. Case Presentation On routine dissection of an embalmed 57 year old male cadaver, variations were found in the formation of divisions and cords of the Brachial Plexus of the right side. Some previously unreported findings observed were; direct branches to the muscles Pectoralis Minor and Latissimus dorsi from C6, innervation of deltoid by C6 and C7 roots and the origin of lateral pectoral nerve from the posterior division of upper trunk. The median nerve was present lateral to axillary artery. The left side brachial plexus was also inspected and found to have normal anatomy. Conclusion The probable cause for such variations and their embryological basis is discussed in the paper. It is also concluded that although these variations may not have affected the functioning of upper limb in this individual, knowledge of such variations is essential in evaluation of unexplained sensory and motor loss after trauma and surgical interventions to the upper limb.

  1. Human body donation programs in Sri Lanka: Buddhist perspectives. (United States)

    Subasinghe, Sandeepani Kanchana; Jones, D Gareth


    Considerable attention is being given to the availability of bodies for anatomical education. This raises the question of the manner in which they are obtained, that is, whether they are unclaimed or donated. With increasing emphasis upon the ethical desirability of using body bequests, the spotlight tends to be focused on those countries with factors that militate against donations. However, little attention has been paid to cultures where donations are readily available. One such country is Sri Lanka where the majority of the Buddhist population follows Theravada Buddhism. Within this context, the expectation is that donations will be given selflessly without expecting anything in return. This is because donation of one's body has blessings for a better outcome now and in the afterlife. The ceremonies to honor donors are outlined, including details of the "Pirith Ceremony." The relevance for other cultures of these features of body donation is discussed paying especial attention to the meaning of altruism and consent, and justification for the anonymization of cadavers. The degree to which anatomy is integrated into the surrounding culture also emerges as significant. © 2015 American Association of Anatomists.

  2. Human cadaveric dissection: a historical account from ancient Greece to the modern era (United States)


    The review article attempts to focus on the practice of human cadaveric dissection during its inception in ancient Greece in 3rd century BC, revival in medieval Italy at the beginning of 14th century and subsequent evolution in Europe and the United States of America over the centuries. The article highlights on the gradual change in attitude of religious authorities towards human dissection, the shift in the practice of human dissection being performed by barber surgeons to the anatomist himself dissecting the human body and the enactment of prominent legislations which proved to be crucial milestones during the course of the history of human cadaveric dissection. It particularly emphasizes on the different means of procuring human bodies which changed over the centuries in accordance with the increasing demand due to the rise in popularity of human dissection as a tool for teaching anatomy. Finally, it documents the rise of body donation programs as the source of human cadavers for anatomical dissection from the second half of the 20th century. Presently innovative measures are being introduced within the body donation programs by medical schools across the world to sensitize medical students such that they maintain a respectful, compassionate and empathetic attitude towards the human cadaver while dissecting the same. Human dissection is indispensable for a sound knowledge in anatomy which can ensure safe as well as efficient clinical practice and the human dissection lab could possibly be the ideal place to cultivate humanistic qualities among future physicians in the 21st century.

    This paper presents the work of constructing Chinese adult anatomical models and their application in evaluation of radio frequency (RF) electromagnetic field exposures. The original dataset was obtained from photos of the sliced frozen cadavers from the Chinese Visible Human Project. Details of preparing the cadaver for slicing procedures which may influence the anatomical structures are discussed. Segmentation and reconstruction were performed mainly manually by experienced anatomists. The reconstructed models represent the average Chinese in their twenties and thirties. The finest resolution for the models is 1 × 1 × 1 mm3 with 90 identified tissues/organs for the female and 87 identified tissues/organs for the male. Tiny anatomical structures such as blood vessels with diameters of 1 mm, various glands and nerves were identified. Whole-body-averaged specific absorption rate (WBSAR) from 20 MHz to 5.8 GHz was calculated with the finite-difference time-domain method for different RF exposure configurations. The WBSAR results are consistent with those from other available models. Finally, some details about the anatomical models are discussed.

    Full Text Available Background: Studies on the estimation of stature from hand and foot length of an individual are essential study in personal identification. Aim and Objectives: This study is to find out correlation between statures with hand and foot dimensions in both sexes and gender comparison from an individual in Lautech Staff College in Ogbomoso and College ogbomoso and College of Health Sciences, Obafemi Awolowo University, Ile-Ife, Nigeria. Material and Methods: A sample of 140 students and staff; 70 male and 70 female Students and staff of Lautech Staff College in Ogbomoso and College ogbomoso and College of Health Sciences, Obafemi Awolowo University, Ile-Ife, between 16-35years were considered and measurements were taken for each of the parameters. Gender differences for the two parameters were determined using Student t-test. Pearson's correlation coefficient (r was used to examine the relationship between two anthropometric parameters and standing height (stature. All these measurements were done by using standard anthropometric instruments and standard anthropometric techniques. Results: The findings of the study indicated that the males mean values are not significantly difference when compared with females mean values in all measured parameters. The study showed significant (p<0.001 positive correlation between the stature with hand lengths and foot lengths. The hand and foot length provide accurate and reliable means in establishing the height of an individual. Conclusion: This study will be useful for forensic scientists and anthropologists as well as anatomists in ascertain medico-legal cases

  5. Mortimer Frank, Johann Ludwig Choulant, and the history of anatomical illustration. (United States)

    Feibel, Robert M


    Mortimer Frank (1874-1919) was an ophthalmologist in Chicago, Illinois. He published a number of papers on the history of medicine, and was secretary of the Chicago Society of the History of Medicine and editor of their Bulletin. His major contribution to the history of medicine relates to the history of anatomical illustration. The classic book on that subject had been published in 1852 in German by the physician and historian, Johann Ludwig Choulant (1791-1861). However, by Frank's time this text was both out dated and out of print. Frank took on the tremendous project of translating Choulant's German text into English as History and Bibliography of Anatomic Illustration in Its Relation to Anatomic Science and The Graphic Arts. He improved Choulant's text with the results of his and other scholars' research, greatly enlarging the text. Frank supplemented the original book with a biography of Choulant, essays on anatomists not considered in the original text, and an essay on the history of anatomical illustration prior to those authors discussed by Choulant. This book, now referred to as Choulant/Frank, has been reprinted several times, and is still useful as a reference in this field, though some of its research is now dated.

  6. [History of German-Baltic relations in medicine]. (United States)

    Tankler, H; Laschinski, G; Roots, I


    Today, the three Baltic countries Estonia, Latvia and Lithuania, have well-known medical faculties with international standing. Their individual histories are briefly outlined. However, relations of the German academic world were closest with the university of Dorpat (today: Tartu). It was re-opened in 1802 by tsar Alexander I in order to keep young Baltic people from studying abroad. The medical faculty was its biggest faculty. The university was Russian, but the official language was German. So many a German professor came to Dorpat and many professors from Dorpat were offered a chair at a German university. The scientific imports connected Dorpat with other centres of West-European science, they brought knowledge and ideas and an exchange of information. The standard was high, and among the teaching staff was a handsome number of medical celebrities, e.g. the anatomist August Rauber and the surgeon Ernst von Bergmann. In Dorpat, Rudolf Buchheim brought a new science, experimental pharmacology, into being, which his pupil and successor, Oswald Schmiedeberg, fully established and propagated all over the world.

  7. Frederik Ruysch (1638–1731): Historical perspective and contemporary analysis of his teratological legacy (United States)

    Boer, Lucas; Radziun, Anna B.


    The Peter the Great Museum of Anthropology and Ethnography (Kunstkamera) in Saint Petersburg is the oldest museum in Russia. It keeps the remains of the anatomical collection of the world‐famous 17th century Dutch anatomist Frederik Ruysch. This unique collection was bought and shipped in 1717 by Czar Peter the Great, and presently still comprises more than 900 specimens, a modest number of which concerns specimens with congenital anomalies. We searched for teratological clues in the existing collection and in all his descriptions and correspondence regarding specimens and cases he encountered during his career as doctor anatomiae and chief instructor of the surgeons and midwives in Amsterdam. A total of 63 teratological specimens and case descriptions were identified in this legacy, including some exceedingly rare anomalies. As it turns out, Ruysch was the first to describe several of the conditions we encountered, including intracranial teratoma, enchondromatosis, and Majewski syndrome. Although his comments pose an interesting view on how congenital anomalies were scientifically perceived in early 18th century Europe, Ruysch mostly refrained from explaining the causes of the conditions he encountered. Instead, he dedicated himself to careful descriptions of his specimens. Almost 300 years after his demise, Ruysch's legacy still impresses and inspires both scientists and lay men. © 2016 The Authors.

  9. The Allan Burns mummies: A history and future prospect of an anatomical collection

    Directory of Open Access Journals (Sweden)

    J Lee


    Full Text Available Acquiring adequate resources for anatomy education has represented a challenge throughout the discipline's long history. A significant number of collections housed in anatomy departments contain human tissue of unknown provenance with some obtained in morally dubious ways. This paper outlines the history and future prospects of one such anatomical assemblage – the Burns Anatomical Collection, currently housed at the University of Maryland (UM. The collection originally contained more than 1000 anatomically prepared mummified human remains. They were produced by the renowned Scottish anatomist Allan Burns in Glasgow in the late eighteenth and early nineteenth centuries. The prepared cadavers became a commodity and after Burns' death, were acquired by his pupil Granville Pattison, who later sold them to the UM. While the origin of these human remains is unknown, historical data suggests that most of the cadavers for the collection were obtained through grave robbing. While intensely used in anatomy teaching in the nineteenth century, specimens from the collection should now be treated primarily as historical artifacts, appropriate only for teaching medical history and ethics. Other perspectives may include repatriating and reburying the human remains and providing a memorial service. Most importantly, this collection and others similar to it should initiate dialog and reflection on the ethical aspects of the past and present medical practice.

  10. Does emotional intelligence change during medical school gross anatomy course? Correlations with students' performance and team cohesion. (United States)

    Holman, Michelle A; Porter, Samuel G; Pawlina, Wojciech; Juskewitch, Justin E; Lachman, Nirusha


    Emotional intelligence (EI) has been associated with increased academic achievement, but its impact on medical education is relatively unexplored. This study sought to evaluate change in EI, performance outcomes, and team cohesion within a team-based medical school anatomy course. Forty-two medical students completed a pre-course and post-course Schutte Self-Report Emotional Intelligence Test (SSEIT). Individual EI scores were then compared with composite course performance grade and team cohesion survey results. Mean pre-course EI score was 140.3 out of a possible 160. During the course, mean individual EI scores did not change significantly (P = 0.17) and no correlation between EI scores and academic performance was noted (P = 0.31). In addition, EI did not correlate with team cohesion (P = 0.16). While business has found significant utility for EI in increasing performance and productivity, its role in medical education is still uncertain. © 2015 American Association of Anatomists.

  11. Heart in anatomy history, radiology, anthropology and art. (United States)

    Marinković, S; Lazić, D; Kanjuh, V; Valjarević, S; Tomić, I; Aksić, M; Starčević, A


    Anthropologic, artistic and medical significance of heart inspired usto undertake this multidisciplinary study. Amongst the 24 obtained echocardiograms and phonograms, 1 was used for a Photoshop processing. In addition, over 20,000 art work reproductions were examined in this study. Artistic and symbolic presentation of heart started some 15,000 years ago. First heart models were made by the Egyptian and Olmec civilisations. Ancient cultures regarded heart as the seat of the soul, spirit and intelligence. First anatomical and artistic images of heart were created by Leonardo da Vinci in the15th century, and first wax models by the Italian anatomists in the 17th century. Mediaeval religious symbolism of heart was replaced in the Renaissance and later on mainly by its role in the romantic love. Anatomical heart art continued in the 18th and 19th centuries through the works of Sénac, Cloquet, Hirschfeldand Bourgery. Some modern artists, such as Dalí, Kahlo, Rivera, Warhol, Ivanjicki, Vital, Kober and Mastrlova, created the anatomical heart images or sculptures, whereas some others, such as Duchamp, Klee, Miró, Matisse and Dine, presented heart symbol in their artworks. New radiologic technologies produce fine images of heart, some of which are similar to the works of modern artists. Heart biology and symbolism have had a tremendous influence on our culture, including art and medical sciences. New radiologic techniques and computer technology have produced such images of heart, which substantially improved diagnosis, but also enhanced the heart aesthetics.

  12. Neural stem cells and neuro/gliogenesis in the central nervous system: understanding the structural and functional plasticity of the developing, mature, and diseased brain. (United States)

    Yamaguchi, Masahiro; Seki, Tatsunori; Imayoshi, Itaru; Tamamaki, Nobuaki; Hayashi, Yoshitaka; Tatebayashi, Yoshitaka; Hitoshi, Seiji


    Neurons and glia in the central nervous system (CNS) originate from neural stem cells (NSCs). Knowledge of the mechanisms of neuro/gliogenesis from NSCs is fundamental to our understanding of how complex brain architecture and function develop. NSCs are present not only in the developing brain but also in the mature brain in adults. Adult neurogenesis likely provides remarkable plasticity to the mature brain. In addition, recent progress in basic research in mental disorders suggests an etiological link with impaired neuro/gliogenesis in particular brain regions. Here, we review the recent progress and discuss future directions in stem cell and neuro/gliogenesis biology by introducing several topics presented at a joint meeting of the Japanese Association of Anatomists and the Physiological Society of Japan in 2015. Collectively, these topics indicated that neuro/gliogenesis from NSCs is a common event occurring in many brain regions at various ages in animals. Given that significant structural and functional changes in cells and neural networks are accompanied by neuro/gliogenesis from NSCs and the integration of newly generated cells into the network, stem cell and neuro/gliogenesis biology provides a good platform from which to develop an integrated understanding of the structural and functional plasticity that underlies the development of the CNS, its remodeling in adulthood, and the recovery from diseases that affect it.

  13. Perceptions of junior doctors and undergraduate medical students as anatomy teachers: Investigating distance along the near-peer teaching spectrum. (United States)

    Hall, Samuel; Stephens, Jonathan; Andrade, Teu; Davids, Joseph; Powell, Matthew; Border, Scott


    Near-peer teaching involves more experienced students acting as tutors and has been widely used in anatomy education. This approach has many advantages for the learner due to the social and cognitive congruence they share with the teacher, however, the influence of distance between the teacher and learner on these congruences has yet to be explored. The aim of this study was to compare the attitudes and perceptions of the student learner towards neuroanatomy review sessions taught by either a senior medical student or a junior doctor. The students were randomly assigned to an allocated tutor. All tutors used standardized material and had access to identical resources. The type of allocated tutor was swapped between the two teaching sessions and 99 student feedback forms were collected in total. The rating for the overall quality of the teaching session was not significantly different between the junior doctors and senior medical students (P = 0.11). However, criteria closely relating to social and cognitive congruence such as "enjoyment of the session," "delivery of the teaching," and "was it a good use of time" were all rated significantly higher for the senior medical students (P distance along the near-peer teaching spectrum have an impact upon the student's perception of their learning experience. While all teachers were suitable role models it appears that junior doctors are too far removed from their own undergraduate experiences to share congruences with pre-clinical medical students. © 2013 American Association of Anatomists.

  14. Yoga asanas as an effective form of experiential learning when teaching musculoskeletal anatomy of the lower limb. (United States)

    Bentley, Danielle C; Pang, Stephen C


    Physical movement as a conduit for experiential learning within the academic context of anatomy is a strategy currently used in university dance education. This same approach can be applied to other movement-based practices, for example, yoga. The primary purpose of this study was to pilot a novel teaching curriculum to yoga practitioners, based on Bruner's Theory of Instruction, which incorporated the four adaptive modes of Kolb's Theory of Experiential Learning. The secondary purpose was to assess the applicability of anatomical knowledge within the participants' yoga practice. Following the development of a curriculum appropriate for a spectrum of academic backgrounds, participants were recruited to attend a 2-hour learning session within the Department of Anatomy at Queen's University in Kingston, Ontario, Canada. The learning session guided participants through the bones and muscles of the lower limb pertaining to five specific yoga poses. Based on participant feedback, the sessions were positively received and consistent. In addition, learning session participants were able to apply the anatomical information they were taught to their yoga practice 1-month later. Bruner and Kolb's independent theories on curriculum design and effective learning practice were successfully incorporated to create a 2-hour learning session. The potential use of experiential learning to compliment and/or enhance traditional didactic teaching in the academic context of anatomy should be further explored.

  15. Charles Edward Isaacs (1811-1860): exploring the details of nephron structure and function in the post-Bowman period. (United States)

    Fine, Leon G


    Charles Edward Isaacs (1811-1860), an anatomist working in New York, undertook a series of studies which attempted to define the microscopic structure of the nephrons in a variety of species. Given that he published his findings 15 years after William Bowman's seminal paper on the subject, he was able to add only a few of the finer details to the picture. He observed the continuity of the epithelium of the glomerular capsule with that of the proximal tubule and he demonstrated that the glomerular tuft is covered by a layer of epithelial cells. In a series of studies on human renal function he erroneously concluded that the glomerulus must have an excretory function in addition to its filtration function and that diuretics act primarily on the glomerlus. The latter conclusion was based upon observations of substances not currently categorized as being diuretic agents. The absence of a major conceptual advance in the writings of Isaacs probably accounts for that fact that his contribution has been largely forgotten.

  16. Bud detachment in hydra requires activation of fibroblast growth factor receptor and a Rho–ROCK–myosin II signaling pathway to ensure formation of a basal constriction (United States)

    Holz, Oliver; Apel, David; Steinmetz, Patrick; Lange, Ellen; Hopfenmüller, Simon; Ohler, Kerstin; Sudhop, Stefanie


    Background: Hydra propagates asexually by exporting tissue into a bud, which detaches 4 days later as a fully differentiated young polyp. Prerequisite for detachment is activation of fibroblast growth factor receptor (FGFR) signaling. The mechanism which enables constriction and tissue separation within the monolayered ecto‐ and endodermal epithelia is unknown. Results: Histological sections and staining of F‐actin by phalloidin revealed conspicuous cell shape changes at the bud detachment site indicating a localized generation of mechanical forces and the potential enhancement of secretory functions in ectodermal cells. By gene expression analysis and pharmacological inhibition, we identified a candidate signaling pathway through Rho, ROCK, and myosin II, which controls bud base constriction and rearrangement of the actin cytoskeleton. Specific regional myosin phosphorylation suggests a crucial role of ectodermal cells at the detachment site. Inhibition of FGFR, Rho, ROCK, or myosin II kinase activity is permissive for budding, but represses myosin phosphorylation, rearrangement of F‐actin and constriction. The young polyp remains permanently connected to the parent by a broad tissue bridge. Conclusions: Our data suggest an essential role of FGFR and a Rho‐ROCK‐myosin II pathway in the control of cell shape changes required for bud detachment.

  17. "No interest in human anatomy as such": Frederic Wood Jones dissects anatomical investigation in the United States in the 1920s. (United States)

    Jones, Ross L


    In 1926, Frederic Wood Jones, professor of Anatomy at the University of Adelaide and a leading figure in the British anatomical world, took a Rockefeller Foundation funded trip to the United States in order to inspect anatomy programmes and medical museums and to meet leading figures in the anatomical and anthropological world. His later reflections paint a picture of a discipline in transition. Physical anthropology and gross anatomy were coming to a crisis point in the United States, increasingly displaced by research in histology, embryology and radiological anatomy. Meanwhile, in Britain and its colonial outposts, anatomists such as Wood Jones were attempting to re-invigorate the discipline in the field, studying biological specimens as functional and active agents in their particular milieus, but with human dissection at the core. Thus, an examination of this trip allows us to see how the interaction between two traditions in anatomy informed the process of the development of human biology in this critical period.

  18. Xylem anatomy of the Caesalpiniaceae registered in wood collection of the Universidad Distrital Francisco Jose de Caldas

    International Nuclear Information System (INIS)

    Pulido Rodriguez, Esperanza N; Mateus, Durley; Lozano D, Ivan


    The anatomical study of the xylem of 21 species of Caesalpiniaceae registered in the wood collection Jos Anatolio Lastra Rivera (JALR), of the Universidad Distrital Francisco Jose de Caldas, included the macroscopic, microscopic and biometric characterization of the cellular elements that constitute the xylematic tissue. These analyses were developed following parameters defined by the International Association Wood Anatomist Committee (IAWA Committee 1989) and methods established by the Wood Technology Laboratory of Universidad Distrital. Measurements and descriptions were used to prepare identification keys and similarity analysis. The wood of Caesalpiniaceae family illustrated common characteristics in growth rings differentiation, porosity, vessel arrangement, deposits, diameter and length, plates perforation type, alternate and vestured intervessel pits; fibers wall thickness and length; paratracheal axial vasicentric parenchyma, aliform and banded parenchyma and presence of prismatic crystals. Also, variations in anatomical features such us longitudinal channels were found as diagnostic for some genera like Copaifera. The variation and analysis of anatomical characteristics of the xylem tissue allowed to verify some taxonomic relations of the family Caesalpiniaceae, like the observed with the species Mora megistosperma, Mora oleofera, Peltogyne pubescens, Peltogyne paniculata, Sclerolobium odoratissimum and Tachigali polyphylla .

  19. The principles, procedures and pitfalls in identifying archaeological and historical wood samples. (United States)

    Cartwright, Caroline R


    The science of wood anatomy has evolved in recent decades to add archaeological and historical wood to its repertoire of documenting and characterizing modern and fossil woods. The increasing use of online wood anatomy databases and atlases has fostered the adoption of an international consensus regarding terminology, largely through the work of the International Association of Wood Anatomists (IAWA). This review presents an overview for the general reader of the current state of principles and procedures involved in the study of the wood anatomy of archaeological and historical specimens, some of which may be preserved through charring, waterlogging, desiccation or mineral replacement. By means of selected case studies, the review evaluates to what extent varying preservation of wood anatomical characteristics limits the level of identification to taxon. It assesses the role played by increasingly accessible scanning electron microscopes and complex optical microscopes, and whether these, on the one hand, provide exceptional opportunities for high-quality imaging and analysis of difficult samples, but, on the other hand, might be misleading the novice into thinking that advanced technology can be a substitute for specialized botanical training in wood anatomy. © The Author 2015.

  20. Voices of donors: case reports of body donation in Hong Kong. (United States)

    Chiu, Hei Yeung; Ng, Kwok Sing; Ma, Sin Kwan; Chan, Chi Hung; Ng, Sheung Wah; Tipoe, George L; Chan, Lap Ki


    Body donation is important for medical education and academic research. However, it is relatively rare in Hong Kong when compared with many Western countries. Comprehensive research has been performed on the motivation for body donation in Western countries; however, there is still insufficient research on body donation in Hong Kong to provide information on how to increase the body-donation rate. To understand the factors involved in the decision to donate one's body, the authors interviewed a registered donor and the daughter of another donor in Hong Kong. The authors interpreted the information collected in light of the available published reports, which mostly focus on body donation in Western countries. Despite the consistency of some demographic factors and motivations between the participants in our study and those investigated in the published reports from Western countries, there are differences in education level and socioeconomic status between the donors in our study and those from Western studies. The authors also suggest that Confucianism and Buddhism in Chinese culture may motivate potential body donors in Hong Kong. Other important factors that influence the body-donation decision may include family members' body donation, registration as organ donors, and good doctor-patient relationships. Although case report studies have their limitations, this study allows us to explore the complexity of events and establish the interconnectivity of factors involved in body donation, which could not be achieved in previous survey-based studies.

  1. Morphology investigation of the mink’s brain (Mustela vison

    Directory of Open Access Journals (Sweden)

    Milanović Valentina


    Full Text Available The mink is a strict carnivore and a seasonal breeder, which may be used as an experimental model for other carnivores. Using anatomical methods, 32 brains of the N. American mink were examined. It was found that the brain consists of four ventricles. Also, it was noted that the posterior horn was missing and that the olfactory recess was present in the lateral ventricle, a large-size interthalamic connection was present in the third ventricle, and a flat, necklace like bottom in the fourth ventricle. Only recently, the ins and outs of the mink’s anatomical structure have begun to absorb the attention of anatomists. Apparently, it is related to the fact that fury animals, among them the mink, are being domesticated. For this reason and because of easy access to the material, the purpose of brain dissection is to familiarize with the three dimensional structure of the brain and teach one of the great methods of studying the brain: looking at its structure.

  2. Student perceptions and effectiveness of an innovative learning tool: Anatomy Glove Learning System. (United States)

    Lisk, Kristina; McKee, Pat; Baskwill, Amanda; Agur, Anne M R


    A trend in anatomical education is the development of alternative pedagogical approaches to replace or complement experiences in a cadaver laboratory; however, empirical evidence on their effectiveness is often not reported. This study aimed to evaluate the effectiveness of Anatomy Glove Learning System (AGLS), which enables students to learn the relationship between hand structure and function by drawing the structures onto a worn glove with imprinted bones. Massage therapy students (n = 73) were allocated into two groups and drew muscles onto either: (1) the glove using AGLS instructional videos (3D group); or (2) paper with palmar/dorsal views of hand bones during an instructor-guided activity (2D group). A self-confidence measure and knowledge test were completed before, immediately after, and one-week following the learning conditions. Self-confidence of hand anatomy in the 3D group gradually increased (3.2/10, 4.7/10, and 4.8/10), whereas self-confidence in the 2D group began to decline one-week later (3.2/10, 4.4/10, and 3.9/10). Knowledge of hand anatomy improved in both groups immediately after learning, (P learning tool (mean = 8.6 ± 2.2). This study provides evidence demonstrating that AGLS and the traditional 2D learning approach are equally effective in promoting students' self-confidence and knowledge of hand anatomy. © 2014 American Association of Anatomists.

  3. The infrabranchial musculature and its bearing on the phylogeny of percomorph fishes (Osteichthyes: Teleostei). (United States)

    Datovo, Aléssio; de Pinna, Mário C C; Johnson, G David


    The muscles serving the ventral portion of the gill arches ( = infrabranchial musculature) are poorly known in bony fishes. A comparative analysis of the infrabranchial muscles in the major percomorph lineages reveals a large amount of phylogenetically-relevant information. Characters derived from this anatomical system are identified and discussed in light of current hypotheses of phylogenetic relationships among percomorphs. New evidence supports a sister-group relationship between the Batrachoidiformes and Lophiiformes and between the Callionymoidei and Gobiesocoidei. Investigated data also corroborate the existence of two monophyletic groups, one including the Pristolepididae, Badidae, and Nandidae, and a second clade consisting of all non-amarsipid stromateiforms. New synapomorphies are proposed for the Atherinomorphae, Blenniiformes, Lophiiformes, Scombroidei (including Sphyraenidae), and Gobiiformes. Within the latter order, the Rhyacichthyidae and Odontobutidae are supported as the successive sister families of all remaining gobiiforms. The present analysis further confirms the validity of infrabranchial musculature characters previously proposed to support the grouping of the Mugiliformes with the Atherinomorphae and the monophyly of the Labriformes with the possible inclusion of the Pholidichthyiformes. Interestingly, most hypotheses of relationships supported by the infrabranchial musculature have been advanced by preceding anatomists on the basis of distinct data sources, but were never recovered in recent molecular phylogenies. These conflicts clearly indicate the current unsatisfactory resolution of the higher-level phylogeny of percomorphs.

  4. Rufus of Ephesus and his contribution to the development of anatomical nomenclature. (United States)

    Bujalkova, Maria


    Rufus of Ephesus, a famous ancient physician, lived about the years 80 - 150 CE. His theories stressed the importance of anatomy and he preferred pragmatic approach to diagnosis and treatment. In his work "On the Names of the Parts of the Human Body", he put in pragmatic effort to make a lexicon of anatomy for his pupils. In the introduction, he described it as a manual for the students of medical art which relied on demonstration in teaching; visible (outer) parts of the body were shown on a demonstrator and invisible (inner) parts were shown on a dissected monkey. The brief explanation of the anatomical terms includes position, shape, and functions of organs, and this is what makes his work a pioneering effort to explain the anatomy clearly, systematically, and using consistent terminology. Rufus stressed the importance of exact nomenclature to prevent misunderstandings in medical practice. This anatomy manual had a major influence on the development of anatomical terminology. It is an important contribution to the history of teaching. The other essential contribution of Rufus' lexicon (also known for its briefer title Onomastikon) is that the author recognised and critically reviewed the knowledge and views of his predecessors, physicians of the pre-Galenic period. No less important was his teaching to anatomists and physicians who followed, as they often cited or paraphrased Rufus in their own works (Galen, Oribasius). Many fragments of Rufus' work have been preserved by medieval Arabic medical writers, especially by Rhazes.

  5. Gaze patterns of gross anatomy students change with classroom learning. (United States)

    Zumwalt, Ann C; Iyer, Arjun; Ghebremichael, Abenet; Frustace, Bruno S; Flannery, Sean


    Numerous studies have documented that experts exhibit more efficient gaze patterns than those of less experienced individuals. In visual search tasks, experts use fewer, longer fixations to fixate for relatively longer on salient regions of the visual field while less experienced observers spend more time examining nonsalient regions. This study investigates whether changes in gaze patterns reflect learning by students in a medical gross anatomy course. Students were asked to examine photographs of dissections similar to those they experienced in class and to identify the tagged structure in each image. We postulated that, compared to naive behavior (behavior at baseline and when examining unfamiliar content) students would examine familiar content for longer and would direct proportionally more fixation time on cognitively salient regions of the images while using fewer, longer duration fixations. Our students examined familiar images for significantly longer than they did at baseline (P patterns were characterized by more numerous fixations rather than fewer, longer fixations. These individuals are successful learners in a challenging gross anatomy course, but are not experts in anatomy. Therefore we speculate that the gaze pattern they exhibit characterizes an earlier stage of the learning process than has previously been documented in studies of expertise, which have primarily focused on the gaze patterns of true experts. © 2014 American Association of Anatomists.

  6. Morphology of the heart associated with its function as conceived by ancient Greeks. (United States)

    Mavrodi, Alexandra; Paraskevas, George


    According to their writings, ancient Greek physicians had explored the anatomy of the heart. Although pre-Hippocratic medicine, which relied on religion and mysticism, has nothing more to present than implausible theories and speculations, younger physicians thanks to their animal dissections were able to depict the heart with detail. Hippocratic "On the Heart", Aristotle's, Herophilus', Erasistratus' and Galen's writings provide us with the necessary data to take a look at the anatomy of the heart as it was described back then. Despite of some confusing passages in their writings and some erroneous notions, the heart was described with relative accuracy. In the years after antiquity and in the Middle Age the only information about the anatomy of the heart could be derived from the ancient Greek works and only anatomists of the Renaissance managed to displace them. In this paper we present the knowledge of all known ancient Greek physicians about the heart, with emphasis on its anatomy. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

  7. Fascia: an illustrative problem in international terminology. (United States)

    Wendell-Smith, C P


    As a result of international nomenclatures being in Latin, with the terms usually being undefined and translated into national vernacular languages, the same terms have been used in different ways in different countries. Fascia is an example of this, the limits of the meaning of the word differing in English-, French- and German-speaking countries. These differences are itemized in a comparative table. In 1989 the General Assembly of the International Federation of Associations of Anatomists [IFAA] created the Federative Committee on Anatomical Terminology [FCAT] with a remit to create a new terminology for the anatomical sciences with full democratic consultation with the member societies of IFAA. The draft recommendations of FCAT on fascia and the reasons for them are given. Problems associated with the use, or lack of use, of international terminologies are illustrated. For the advancement of medical knowledge and understanding, the cooperation of authors, editors and publishers in using the current terminology in the right way remains of critical importance. It is suggested that, after adopting a terminology, IFAA has a responsibility to arrange for technical back-up.

  8. The perceived importance of anatomy and neuroanatomy in the practice of speech-language pathology. (United States)

    Martin, Kate; Bessell, Nicola J; Scholten, Ingrid


    The purpose of this study was to examine the application of anatomy and neuroanatomy knowledge to current practice of speech-language pathology (SLP), based on the perceptions of practicing SLPs, and to elicit information on participants' experiences of learning these subjects in their primary SLP degree with a view to inform potential curriculum development. A qualitative approach was taken to the collection of data. Eight practicing SLPs from four settings were interviewed. The critical incident technique, together with further probing, was used to elicit information. Interviews were transcribed and later thematically analyzed. This study found that knowledge of anatomy and neuroanatomy was perceived to be important by SLPs across all settings, to varying degrees, with a greater application in acute hospital settings. Negative experiences in studying this material were reported across all settings regardless of country of study. Participants discussed ways to increase students' motivation to learn this challenging material. Relevance of material demanded by students may be enhanced if active learning methods were used to teach anatomy/neuroanatomy, including case-based learning and with vertical and horizontal integration of material to provide a cohesive, spiral curriculum. © 2013 American Association of Anatomists.

  9. Synthesis and Race: Barge, Buytendijk, and the rassenvraagstuk of the 1930s

    Directory of Open Access Journals (Sweden)

    Sebastiaan Broere


    Full Text Available On the basis of two case studies, this article demonstrates that throughout the 1930s “synthetic reasoning” in the Netherlands provided arguments to denounce racial reductionism and eugenicist policy. These two case studies concern the anatomist and physical anthropologist J.A.J. Barge (1884-1952 and the physiologist and psychologist F.J.J. Buytendijk (1887-1974. Barge and Buytendijk participated in a public debate on race and fiercely contested the claim – from their perspective primarily defended by German scientists – that heritable, racial factors determined personality and physiology. Christian principles undoubtedly motivated Barge and Buytendijk to raise their voices, but in criticizing the public uses of race, they based their arguments, above all, on epistemological considerations. This article examines theoretical investigations by Buytendijk and Barge into the foundations of the life sciences, the “race question” of the 1930s, and the 1939 Seminar on the Race Question organized by the Catholic University in Nijmegen. Although both intellectuals supported the broadening of explanatory schemes in biology and the human sciences, they differed on the question what synthesis meant with regard to the concept of race.

  10. Peer mentoring program in an interprofessional and interdisciplinary curriculum in Brazil. (United States)

    de Oliveira, Camila Aparecida Machado; de França Carvalho, Carolina Prado; Céspedes, Isabel Cristina; de Oliveira, Flávia; Le Sueur-Maluf, Luciana


    The Federal University of São Paulo, Baixada Santista Campus was founded in 2006 with five degree-granting programs in physical education, physiotherapy, nutrition, psychology, and occupational therapy. The guiding principle behind the programs' educational mission was centered on the development of health care professionals capable of working in interdisciplinary teams with an emphasis on holistic patient care. This pedagogical structure required peer-mentoring programs in order to integrate different areas of knowledge and to improve learning strategies among new generations of students. The authors' objective in the present report is to discuss the strategies and activities of the peer-mentoring program in histophysiology and gross anatomy in an interdisciplinary and interprofessional curriculum. Evaluations by students, mentors and professors are presented, along with a statistical analysis of variance comparing student performance in the module assessments according to their participation in the peer-mentoring activities. The results demonstrated that students who participated in peer-mentoring activities enjoyed a higher rate of academic success than those who did not participate. In addition, student and mentor evaluations of the peer mentoring program were highly positive. The program enabled mentors to gain a deeper knowledge of the subjects addressed in the learning modules, as well as to develop intrinsic teaching skills during their time as mentors. In short, the authors believe that the peer-mentoring program has been validated for its effectiveness in raising student academic performance. © 2015 American Association of Anatomists.

  11. Was Darwin a creationist? (United States)

    Cosans, Chris


    Throughout the Origin of Species, Darwin contrasts his theory of natural selection with the theory that God independently created each species. This makes it seem as though the Origin offers a scientific alternative to a theological worldview. A few months after the Origin appeared, however, the eminent anatomist Richard Owen published a review that pointed out the theological assumptions of Darwin's theory. Owen worked in the tradition of rational morphology, within which one might suggest that evolution occurs by processes that are continuous with those by which life arises from matter; in contrast, Darwin rested his account of life's origins on the notion that God created one or a few life forms upon which natural selection could act. Owen argued that Darwin's reliance on God to explain the origins of life makes his version of evolution no less supernatural than the special creationist that Darwin criticizes: although Darwin limits God to one or a few acts of creation, he still relies upon God to explain life's existence.

  12. Emanuel Edward Klein's book on diseases of birds. (United States)

    Atalić, Bruno


    Emanuel Edward Klein (1844 - 1925) was a British microbiologist of Croatian origin. He was born in Osijek in what is currently the Republic of Croatia and which was then part of the Habsburg Monarchy, he completed his medical studies in Vienna in 1869, and went on to spend his entire career in London. Although trained as an anatomist, embryologist and histologist, his main area of research was microbiology. Due to the fact that back then it was a new and fast developing discipline, he was able to pursue his interests in many directions and make significant discoveries, such as the identification of the 'Bacillus enteritidis sporogenes' as a cause of summer hospital diarrhoeas. Although the overwhelming majority of his researches dealt with bacteria which attacked humans, in 1892 he published a book entitled The Etiology and Pathology of Grouse Disease, Fowl Enteritis, and Some Other Diseases Affecting Birds, which revealed the results of his experiments on the bacteria which affected birds. In the context of the general development of the microbiology, this paper tries to give an objective evaluation of this until now widely neglected book.

  13. Good teaching is good teaching: A narrative review for effective medical educators. (United States)

    Berman, Anthony C


    Educators have tried for many years to define teaching and effective teachers. More specifically, medical educators have tried to define what characteristics are common to successful teachers in the healthcare arena. The goal of teacher educators has long been to determine what makes an effective teacher so that they could do a better job of preparing future teachers to have a positive impact on the learning of their students. Medical educators have explored what makes some of their colleagues more able than others to facilitate the development of healthcare professionals who can successfully and safely meet the needs of future patients. Although there has historically been disagreement regarding the characteristics that need be developed in order for teachers to be effective, educational theorists have consistently agreed that becoming an effective teacher is a complex task. Such discussions have been central to deciding what education at any level is really all about. By exploring the literature and reflecting upon the personal experiences encountered in his lengthy career as a teacher, and as a teacher of teachers, the author reaches the conclusions that teaching is both art and science, that "good teaching is good teaching" regardless of the learning environment or the subject to be explored, and that the characteristics making up an effective medical educator are really not much different than those making up effective educators in any other area. © 2015 American Association of Anatomists.

  14. The state of radiologic teaching practice in preclinical medical education: survey of American medical, osteopathic, and podiatric schools. (United States)

    Rubin, Zachary; Blackham, Kristine


    This study describes the state of preclinical radiology curricula in North American allopathic, osteopathic, and podiatric medical schools. An online survey of teaching methods, radiology topics, and future plans was developed. The Associations of American Medical Colleges, Colleges of Osteopathic Medicine, and Colleges of Podiatric Medicine listing for all US, Canadian, and Puerto Rican schools was used for contact information for directors of anatomy and/or radiology courses. Letters were sent via e-mail to 198 schools, with a link to the anonymous survey. Of 198 schools, 98 completed the survey (48%). Radiology curricula were integrated with other topics (91%), and taught by anatomists (42%) and radiologists (43%). The majority of time was spent on the topic of anatomy correlation (35%). Time spent teaching general radiology topics in the curriculum, such as physics (3%), modality differences (6%), radiation safety (2%), and contrast use (2%) was limited. Most schools had plans to implement an innovative teaching method in the near future (62%). The major challenges included limits on: time in the curriculum (73%); resources (32%); and radiology faculty participation (30%). A total of 82% reported that their curriculum did not model the suggestions made by the Alliance of Medical Student Educators in Radiology. This survey describes the current state of preclinical radiology teaching: curricula were nonstandard, integrated into other courses, and predominantly used for anatomy correlation. Other important contextual principles of the practice of radiology were seldom taught. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

  15. Rudbeck's complaint: a 17th-century Latin letter relating to basic immunology. (United States)

    Ambrose, C T


    Basic immunology can be said to have its origin in the mid-17th-century with the discovery of the peripheral lymphatics. They completed the gross anatomical picture of the lymphatic system, which is the basis for much of the immune response. Their recognition almost simultaneously by two Scandinavian anatomists led to a protracted war of words over priority of discovery, pitting a young Swedish medical student (Olof Rudbeck) against an honored Danish anatomy professor (Thomas Bartholin). In a 752-word letter in Latin, Rudbeck charged Bartholin with pre-dating a key observation, thereby giving priority of discovery to the latter. The purpose of this paper is to provide an English translation of this accusatory letter. It is a notable document in basic immunology, for it cites much of the knowledge then current in the field. And by raising the issue of priority, the letter indirectly piqued the interest of the scientific community in the lymphatic system and hastened its study. Examining the system's various functions in health and disease led to this new discipline.

  16. Gyration of the feline brain: localization, terminology and variability. (United States)

    Pakozdy, A; Angerer, C; Klang, A; König, E H; Probst, A


    The terminology of feline brain gyration is not consistent and individual variability has not been systematically examined. The aim of the study was to identify the gyri and sulci of cat brains and describe them using the current terminology. The brains of 15 cats including 10 European shorthairs, 2 Siamese, 2 Maine coons and one Norvegian forest cat without clinical evidence of brain disease were examined post-mortem and photographed for documentation. For description, the terms of the most recent Nomina Anatomica Veterinaria (NAV, 2012) were used, and comparisons with previous anatomical texts were also performed. In addition to the lack of comparative morphology in the NAV, veterinary and human nomenclature are used interchangeably and inconsistently in the literature. This presents a challenge for neurologists and anatomists in localizing gyri and sulci. A comparative analysis of brain gyration showed only minor individual variability among the cats. High-quality labelled figures are provided to facilitate the identification of cat brain gyration. Our work consolidates the current and more consistent gyration terminology for reporting the localization of a cortical lesion based on magnetic resonance imaging or histopathology. This will facilitate not only morphological but also functional research using accurate anatomical reporting. © 2014 Blackwell Verlag GmbH.

  17. A pilot study comparing the use of Thiel- and formalin-embalmed cadavers in the teaching of human anatomy. (United States)

    Balta, Joy Y; Lamb, Clare; Soames, Roger W


    Formalin had traditionally been used to preserve human material to teach gross anatomy. In 2008 the Centre for Anatomy and Human Identification (CAHID) at the University of Dundee embarked on the use of the Thiel method of embalming. The aim of this pilot study was to assess the difference between formalin-embalmed cadavers (FEC) and Thiel-embalmed cadavers (TEC) used for teaching and surgical training. Three different questionnaires were prepared for data collection from undergraduate and postgraduate students and clinical staff. All undergraduate and postgraduate students as well as clinical staff commented on the appearance of the TEC. There was no overall consensus concerning the use of TEC, some respondents preferred TEC for the entire dissection, some only for certain areas such as the musculoskeletal system. On a technical level TEC were considered less hazardous then FEC by one-third of participants with fewer than 10% regarding TEC as more irritating than FEC. Psychologically, 32.7% of undergraduate students expressed the view that TEC made them feel more uncomfortable compared with FEC because of their life-like appearance. However, 57.1% of undergraduate students encountered the same uncomfortable feelings when viewing both TEC and FEC. The use of Thiel-embalmed cadavers to teach anatomy has an added value, though further research is required over longer periods of time to identify its best usage. © 2014 American Association of Anatomists.

  18. [A journey into the (un)known. Borderlands of knowledge for Leonhard Rauwolf (1535?-1596)]. (United States)

    Walter, Tilmann


    The Augsburg physician Leonhard Rauwolf is known to the history of Western sciences for "discovering" the exotic flora of the Near East. This article deals with the social background of his studies in Germany and France and his perception of foreign lands, plants, and peoples. Before Rauwolf started his journey at Marseille in 1573 he had received a proper education in practical botany at Montpellier under Guillaume Rondelet. He had also collected about 600 specimens of plants in his herbarium. According to the common medical conventions of his time--most prominently represented by the Renaissance anatomist Andreas Vesalius--in his travel account Rauwolf claimed to tell only what he had seen, experienced, observed by himself, or touched with his own hands. Contrary to his own claim of pure "autopsy", or direct experience, however, Rauwolf's Aigentliche Beschreibung [Actual Description] was composed from different sources. As previously unnoted manuscript letters from the Trew-collection at the University Library of Erlangen show, editorial work on Rauwolf's book was a lengthy process. The final composition ended up drawing on such different sources as the Old and New Testament, ancient natural philosophy, Christian travel literature and sermons, more recent botanical books, oral information from other academics, fellow travellers or indigenous people, and--finally--Rauwolf's own mpressions and observations.

  19. Matters of Priority: Herbert Mayo, Charles Bell and Discoveries in the Nervous System (United States)

    Bradley, James


    Between 1822 and the late 1830s a highly personal priority dispute was fought between the celebrated surgeon and anatomist Sir Charles Bell and his ex-student Herbert Mayo. The dispute was over the motor and sensory functions of the Vth and VIIth cranial nerves. Over the course of the 1820s and the 1830s, the competing claims of Bell and Mayo were presented in newspapers, journals, and textbooks. But by the time of Bell’s death in 1842, Mayo had been discredited, a seemingly tragic footnote in the history of nervous discovery. And yet, with the benefit of hindsight, Bell’s case was at best disingenuous. His success was not due to any intrinsic scientific merit in his argument, but rather his ability to create a narrative that undermined the credibility of Mayo. However, only when Mayo’s public performances elided with Bell’s descriptions did this ploy succeed. As a result, the dispute illuminates the importance of credibility to the creation of an idealised scientific medical practitioner. PMID:25284895

  20. Effectiveness of three-dimensional digital animation in teaching human anatomy in an authentic classroom context. (United States)

    Hoyek, Nady; Collet, Christian; Di Rienzo, Franck; De Almeida, Mickael; Guillot, Aymeric


    Three-dimensional (3D) digital animations were used to teach the human musculoskeletal system to first year kinesiology students. The purpose of this study was to assess the effectiveness of this method by comparing two groups from two different academic years during two of their official required anatomy examinations (trunk and upper limb assessments). During the upper limb section, the teacher used two-dimensional (2D) drawings embedded into PowerPoint(®) slides and 3D digital animations for the first group (2D group) and the second (3D group), respectively. The same 3D digital animations were used for both groups during the trunk section. The only difference between the two was the multimedia used to present the information during the upper limb section. The 2D group surprisingly outperformed the 3D group on the trunk assessment. On the upper limb assessment no difference in the scores on the overall anatomy examination was found. However, the 3D group outperformed the 2D group in questions requiring spatial ability. Data supported that 3D digital animations were effective instructional multimedia material tools in teaching human anatomy especially in recalling anatomical knowledge requiring spatial ability. The importance of evaluating the effectiveness of a new instructional material outside laboratory environment (e.g., after a complete semester and on official examinations) was discussed. © 2014 American Association of Anatomists.

  1. Virtual cerebral ventricular system: an MR-based three-dimensional computer model. (United States)

    Adams, Christina M; Wilson, Timothy D


    The inherent spatial complexity of the human cerebral ventricular system, coupled with its deep position within the brain, poses a problem for conceptualizing its anatomy. Cadaveric dissection, while considered the gold standard of anatomical learning, may be inadequate for learning the anatomy of the cerebral ventricular system; even with intricate dissection, ventricular structures remain difficult to observe. Three-dimensional (3D) computer reconstruction of the ventricular system offers a solution to this problem. This study aims to create an accurate 3D computer reconstruction of the ventricular system with surrounding structures, including the brain and cerebellum, using commercially available 3D rendering software. Magnetic resonance imaging (MRI) scans of a male cadaver were segmented using both semiautomatic and manual tools. Segmentation involves separating voxels of different grayscale values to highlight specific neural structures. User controls enable adding or removing of structures, altering their opacity, and making cross-sectional slices through the model to highlight inner structures. Complex physiologic concepts, such as the flow of cerebrospinal fluid, are also shown using the 3D model of the ventricular system through a video animation. The model can be projected stereoscopically, to increase depth perception and to emphasize spatial relationships between anatomical structures. This model is suited for both self-directed learning and classroom teaching of the 3D anatomical structure and spatial orientation of the ventricles, their connections, and their relation to adjacent neural and skeletal structures.

  2. Integration of gross anatomy in an organ system-based medical curriculum: strategies and challenges. (United States)

    Brooks, William S; Woodley, Kristina T C Panizzi; Jackson, James R; Hoesley, Craig J


    The University of Alabama School of Medicine (UASOM) instituted a fully integrated, organ system-based preclinical curriculum in 2007. Gross anatomy and embryology were integrated with other basic science disciplines throughout the first two years of undergraduate medical education. Here we describe the methods of instruction and integration of gross anatomy and embryology in this curriculum as well as challenges faced along the way. Gross anatomy and embryology are taught through a combination of didactic lectures, team-based learning activities, and cadaveric dissection laboratories. Vertical integration occurs through third- and fourth-year anatomy and embryology elective courses. Radiology is integrated with anatomy instruction through self-study modules and hands-on ultrasound sessions. Our model of anatomy instruction is time efficient, clinically relevant, and effective as demonstrated by student performance on the United States Medical Licensing Examination(®) (USMLE(®) ) Step 1 examination. We recommend that medical schools considering full integration of gross anatomy and embryology (1) carefully consider the sequencing of organ system modules, (2) be willing to sacrifice anatomical detail for clinical application, (3) provide additional electives to third- and fourth-year students, and (4) integrate radiology with anatomical education. © 2014 American Association of Anatomists.

  3. Made in Italy for hernia: the Italian history of groin hernia repair. (United States)

    Negro, Paolo; Gossetti, Francesco; Ceci, Francesca; D'Amore, Linda


    The history of groin hernia surgery is as long as the history of surgery. For many centuries doctors, anatomists and surgeons have been devoted to this pathology, afflicting the mankind throughout its evolution. Since ancient times the Italian contribution has been very important with many representative personalities. Authors, investigators and pioneers are really well represented. Every period (the classic period, the Middle Age, the Renaissance and the post-Renaissance) opened new perspectives for a better understanding. During the 18th century, more information about groin anatomy, mainly due to Antonio Scarpa, prepared the Bassini revolution. Edoardo Bassini developed the first modern anatomically based hernia repair. This procedure spread worldwide becoming the most performed surgical technique. After World War II synthetic meshes were introduced and a new era has begun for hernia repair, once again with the support of Italian surgeons, first of all Ermanno Trabucco. But Italian contribution extends also to educational, with the first national school for abdominal wall surgery starting in Rome, and to Italian participation and support in international scientific societies. Authors hereby wish to resume this long history highlighting the "made in Italy" for groin hernia surgery. Bassini, Groin hernia, History, Prosthetic repair.

  4. Report of an unusual combination of arterial, venous and neural variations in a cadaveric upper limb. (United States)

    Troupis, Theodore G; Michalinos, Adamantios; Manou, Vasiliki; Vlastos, Dimitrios; Johnson, Elizabeth O; Demesticha, Theano; Skandalakis, Panayiotis


    In this study an unusual combination of arterial, venous and neural variations discovered during dissection of cervical, axillary and brachial area of a cadaver is described. Variations are thoroughly described and literature is briefly reviewed. Lateral cord of brachial plexus was not formed; Eight Cervical root divided into anterior and posterior division before uniting with First Thoracic root and Upper Trunk was unusually short. Axillary artery gave origin to a superficial brachial artery and then continued as deep brachial artery. Multiple variations in typical axillary artery branches were present including existence of inferior pectoral artery. Cephalic vein was absent. A variety of interventions, from relative simple as central venous catheter placement to most complicated as brachial plexus injury repair demand thorough knowledge of area's regional anatomy. Familiarity with anatomic variations allows more precise and careful interventions. Research on these variations is valuable for anatomists and embryologists but also for clinicians because it may provide useful information for non - typical cases but also helps in raising a high level of suspicion.

  5. Systematic reviews versus narrative reviews in clinical anatomy: Methodological approaches in the era of evidence-based anatomy. (United States)

    Henry, Brandon Michael; Skinningsrud, Bendik; Vikse, Jens; Pękala, Przemysław A; Walocha, Jerzy A; Loukas, Marious; Tubbs, R Shane; Tomaszewski, Krzysztof A


    Two main types of review articles with distinct characteristics and goals are commonly found in the scientific literature: systematic reviews and narrative (also called expert or traditional) reviews. Narrative reviews are publications that describe and discuss the state of science on a specific topic or theme from a theoretical and contextual point of view with little explicit structure for gathering and presenting evidence. Systematic reviews are overviews of the literature undertaken by identifying, critically appraising and synthesizing the results of primary research studies using an explicit methodological approach. With the recent rise of evidence-based anatomy, important questions arise with respect to the utility of narrative reviews in clinical anatomy. The goal of this perspective article is to address the key differences between narrative and systematic reviews in the context of clinical anatomy, to provide guidance on which type of review is most appropriate for a specific issue, and to summarize how the two types of reviews can work in unison to enhance the quality of anatomical research and its delivery to clinicians and anatomists alike.

  6. Anatomy drawing screencasts: enabling flexible learning for medical students. (United States)

    Pickering, James D


    The traditional lecture remains an essential method of disseminating information to medical students. However, due to the constant development of the modern medical curriculum many institutions are embracing novel means for delivering the core anatomy syllabus. Using mobile media devices is one such way, enabling students to access core material at a time and place that suits their specific learning style. This study has examined the effect of five anatomy drawing screencasts that replicate the popular anatomy drawing element of a lecture. These resources were uploaded to the University's Virtual Learning Environment for student access. Usage data and an end of module questionnaire were used to assess the impact of the screencasts on student education. The data revealed a high level of usage that varied in both the time of day and day of the week, with the number of downloads dramatically increasing towards the end of the module when the assessment was approaching. The student group found the additional resources extremely useful in consolidating information and revision, with many commenting on their preference to the screencasts compared to the more traditional approaches to learning. Scrutinizing the screencasts in relation to cognitive load theory and the cognitive theory of multimedia learning indicates a high correlation with an evidence-based approach to designing learning resources. Overall the screencasts have been a well-received enhancement that supports the student learning and has been shown to promote flexible learning. © 2014 American Association of Anatomists.

  7. Perceptions of a mobile technology on learning strategies in the anatomy laboratory. (United States)

    Mayfield, Chandler H; Ohara, Peter T; O'Sullivan, Patricia S


    Mobile technologies offer new opportunities to improve dissection learning. This study examined the effect of using an iPad-based multimedia dissection manual during anatomy laboratory instruction on learner's perception of anatomy dissection activities and use of time. Three experimental dissection tables used iPads and three tables served as a control for two identical sessions. Trained, non-medical school anatomy faculty observers recorded use of resources at two-minute intervals for 20 observations per table. Students completed pre- and post-perception questionnaires. We used descriptive and inferential analyses. Twenty-one control and 22 experimental students participated. Compared with controls, experimental students reported significantly (P learning anatomy. Experimental students indicated that the iPad helped them in dissection. We observed experimental students more on task (93% vs. 83% of the time) and less likely to be seeking an instructor (2% vs. 32%). The groups received similar attention from instructors (33% vs. 37%). Fifty-nine percent of the time at least one student was looking at the iPad. Groups clustered around the iPad a third of their time. We conclude that the iPad-manual aided learner engagement, achieved instructional objectives, and enhanced the effectiveness and efficiency of dissection education.

  8. Galen. On my own books

    Directory of Open Access Journals (Sweden)

    Irina Prolygina


    Full Text Available In the treatise On my own books (De libris propriis Galen explains why there have been circulating many forgeries, entitled by his name, in the book market of Roman Empire, and gives a list of his authentic works with a short description of each of them. In his notes to his books Galen discusses the content of each book, and describes historical circumstances of its appearance, specificity of its genre and its addressee. This work contains a unique historical information on Galen’s childhood, on the two periods of his life in Rome, on the fire which took place in the Temple of Peace in Rome in 192 A.D., on the plague which burst out during the reign of Antonius Pius, and on the agonistic nature of the medical profession in Rome in the 2nd–3rd cent. C.E. Moreover this work is an important source for the history of ancient philosophy and medicine, because Galen mentions the titles and even summaries of many lost works of his own as well as of his famous predecessors and contemporaries — philosophers and physicians. In particular, he mentions two great anatomists of antiquity — Marinus and Likus. The treatise «On my own books» is one of the most frequently cited works of Galen and may serve as an introduction to his thought. The first Russian translation of this work is provided with a short introduction and detailed commentary.

  9. Effect of didactically qualified student tutors on their tutees' academic performance and tutor evaluation in the gross anatomy course. (United States)

    Horneffer, A; Fassnacht, U; Oechsner, W; Huber-Lang, M; Boeckers, T M; Boeckers, A


    Peer teaching is widely applied in medical education, anatomists having a notably long tradition in cooperating with student tutors in the dissection course. At Ulm University we established an intensified concomitant didactic training program for student tutors and investigated possible effects on their tutees' academic performance and tutor evaluation. In winter semester 2012/13 all student tutors of the dissection course were invited to participate in the "Train-the-Tutor" educational program. 1 Test results and failure rates of 149 tutees who had been supervised by program participants (n=14) and 136 tutees of not participating tutors (n=13) were analyzed, as well as data on tutor evaluation and learning behavior of 235 (82%) of these tutees. Overall, both groups of tutees showed equal learning behavior and evaluated their tutors' performances similarly. However, tutees of program participants consistently obtained better examination results (median: 1.9 versus 2.2 in overall scores) and lower ultimate failure rates (13.4 versus 17.6% of students failed, respectively). An intensified didactic training program for student tutors may help their tutees to pass the gross anatomy course. Additional studies are necessary to objectify and further investigate this effect in order to optimize the concept regarding time expenditure and costs. Copyright © 2016 Elsevier GmbH.

    Full Text Available BACKGROUND : Stature is the height of the person in the upright posture. It is an important measure of physical identity. Estimation of body height from its segments or dismember parts has important considerations for identifications of living or dead human body or remains recovered from disasters or other similar conditions. OBJECTIVE : Stature is an important indicator for identification. There are numerous means to establish stature and their significance lies in the simplicity of measurement, applicability and accuracy in prediction. Our aim of the study was to review the relationship between foot length and body height. METHODS : The present study reviews various prospective studies which were done to estimate the stature. All the measurements were taken by using standard measuring devices and standard anthropometric techniques. RESULTS : This review shows there is a correlation between stature and foot dimensions it is found to be positive and statistically highly significant. Prediction of stature was found to be most accurate by multiple regression analysis. CONCLUSIONS : Stature and gender estimation can be done by using foot measurements and stud y will help in medico - legal cases in establishing identity of an individual and this would be useful for Anatomists and Anthropologists to calculate stature based on foot length

  11. Designing learning spaces for interprofessional education in the anatomical sciences. (United States)

    Cleveland, Benjamin; Kvan, Thomas


    This article explores connections between interprofessional education (IPE) models and the design of learning spaces for undergraduate and graduate education in the anatomical sciences and other professional preparation. The authors argue that for IPE models to be successful and sustained they must be embodied in the environment in which interprofessional learning occurs. To elaborate these arguments, two exemplar tertiary education facilities are discussed: the Charles Perkins Centre at the University of Sydney for science education and research, and Victoria University's Interprofessional Clinic in Wyndham for undergraduate IPE in health care. Backed by well-conceived curriculum and pedagogical models, the architectures of these facilities embody the educational visions, methods, and practices they were designed to support. Subsequently, the article discusses the spatial implications of curriculum and pedagogical change in the teaching of the anatomical sciences and explores how architecture might further the development of IPE models in the field. In conclusion, it is argued that learning spaces should be designed and developed (socially) with the expressed intention of supporting collaborative IPE models in health education settings, including those in the anatomical sciences. © 2015 American Association of Anatomists.

  12. Correlating students' educational background, study habits, and resource usage with learning success in medical histology. (United States)

    Selvig, Daniel; Holaday, Louisa W; Purkiss, Joel; Hortsch, Michael


    Histology is a traditional core basic science component of most medical and dental education programs and presents a didactic challenge for many students. Identifying students that are likely to struggle with histology would allow for early intervention to support and encourage their learning success. To identify student characteristics that are associated with learning success in histology, three first-year medical school classes at the University of Michigan (>440 students) were surveyed about their educational background, attitudes toward learning histology, and their use of histology learning strategies and resources. These characteristics were linked with the students' quiz and examination results in histology. Students who reported previous experience in histology or pathology and hold science or biomedical science college degrees usually did well in histology. Learning success in histology was also positively associated with students' perception that histology is important for their professional career. Other positive indicators were in-person participation in teacher-guided learning experiences, specifically lecture and laboratory sessions. In contrast, students who relied on watching histology lectures by video rather than going to lectures in-person performed significantly worse. These characteristics and learning strategies of students who did well in this very visual and challenging study subject should be of help for identifying and advising students early, who might be at risk of failing a histology course or component. © 2014 American Association of Anatomists.

  13. The internal calcar septum (femoral thigh spur) in computed tomography and conventional radiography

    Energy Technology Data Exchange (ETDEWEB)

    Adam, F. [Orthopaedic Dept., University Hospital of Saarland, Homburg/Saar (Germany); Universitaetskliniken des Saarlandes, Orthopaedische Klinik und Poliklinik, 66421 Homburg/Saar (Germany); Hammer, D.S.; Pape, D.; Kohn, D. [Orthopaedic Dept., University Hospital of Saarland, Homburg/Saar (Germany)


    Objective. The femoral ''thigh spur'', a cortical septum in the region of the lesser trochanter of the human femur, was first described and named by the German anatomist Merkel in 1874, but it was never examined in detail. To evaluate the frequency and the shape of this structure, a combined anatomical and radiological study was performed using saw-cuts from specimens, high-resolution CT and conventional radiography.Design. Thirty human cadaveric femora of central European origin were analyzed by high-precision computed tomography (CT) using thin slices and high-resolution imaging. The CT data were image processed with thresholding to obtain a reconstruction of high-density bone formations and for three-dimensional imaging. Additionally three macerated femur specimens were cut exactly corresponding to the CT slices. The computed images were validated with the anatomical saw-cuts.Results. A dense trabecular ridge protruding endosteally from the posteromedial cortex was found in all femora. This cortical septum reaching from the femoral neck to the distal part of the lesser trochanter separated the femoral cavity from the cancellous bone inside the lesser trochanter. On conventional radiography the femoral thigh spur could be visualized best in the frog-lateral view of the hip.Conclusion. The internal calcar septum is a constant cortical structure. It should be recognized when radiographs or CT images of the proximal femur are interpreted. It could be of importance for metaphyseal fitting of an endoprosthetic stem. (orig.)

  14. Unraveling the multiscale structural organization and connectivity of the human brain: the role of diffusion MRI

    Directory of Open Access Journals (Sweden)

    Matteo eBastiani


    Full Text Available The structural architecture and the anatomical connectivity of the human brain show different organizational principles at distinct spatial scales. Histological staining and light microscopy techniques have been widely used in classical neuroanatomical studies to unravel brain organization. Using such techniques is a laborious task performed on 2-dimensional histological sections by skilled anatomists possibly aided by semi-automated algorithms. With the recent advent of modern magnetic resonance imaging (MRI contrast mechanisms, cortical layers and columns can now be reliably identified and their structural properties quantified post mortem. These developments are allowing the investigation of neuroanatomical features of the brain at a spatial resolution that could be interfaced with that of histology. Diffusion MRI and tractography techniques, in particular, have been used to probe the architecture of both white and gray matter in three dimensions. Combined with mathematical network analysis, these techniques are increasingly influential in the investigation of the macro-, meso- and microscopic organization of brain connectivity and anatomy, both in vivo and ex vivo. Diffusion MRI-based techniques in combination with histology approaches can therefore support the endeavor of creating multimodal atlases that take into account the different spatial scales or levels on which the brain is organized. The aim of this review is to illustrate and discuss the structural architecture and the anatomical connectivity of the human brain at different spatial scales and how recently developed diffusion MRI techniques can help investigate these.

  15. Raymond de Vieussens and his contribution to the study of white matter anatomy: historical vignette. (United States)

    Vergani, Francesco; Morris, Christopher M; Mitchell, Patrick; Duffau, Hugues


    In recent years, there has been a renewed interest in the study of white matter anatomy, both with the use of postmortem dissections and diffusion tensor imaging tractography. One of the precursors in the study of white matter anatomy was Raymond de Vieussens (1641-1716), a French anatomist born in Le Vigan. He studied medicine at the University of Montpellier in southern France, one of the most ancient and lively schools of medicine in Europe. In 1684 Vieussens published his masterpiece, the Neurographia Universalis, which is still considered one of the most complete and accurate descriptions of the nervous system provided in the 17th century. He described the white matter of the centrum ovale and was the first to demonstrate the continuity of the white matter fibers from the centrum ovale to the brainstem. He also described the dentate nuclei, the pyramids, and the olivary nuclei. According to the theory of Galen, Vieussens considered that the function of the white matter was to convey the "animal spirit" from the centrum ovale to the spinal cord. Although neglected, Vieussens' contribution to the study of white matter is relevant. His pioneering work showed that the white matter is not a homogeneous substance, but rather a complex structure rich in fibers that are interconnected with different parts of the brain. These initial results paved the way to advancements observed in later centuries that eventually led to modern hodology.

  16. The dawn of chelonian research: turtles between comparative anatomy and embryology in the 19th century. (United States)

    MacCord, Kate; Caniglia, Guido; Moustakas-Verho, Jacqueline E; Burke, Ann C


    Many evo-devo studies of the turtle's shell draw hypotheses and support from historical sources. The groundbreaking works of Cuvier, Geoffroy St. Hilaire, Carus, Rathke, Owen, and others are being revived in modern research, and their centuries-old understanding of the turtle's shell reconsidered. In the works of these eminent biologists of the 19th century, comparative anatomy and embryology of turtle morphology set the stage for future studies in developmental biology, histology, and paleontology. Given the impact that these works still make on modern research, it is important to develop a thorough appreciation of previous authors, regarding how they arrived at their conclusions (i.e., what counted as evidence?), whether there was debate amongst these authors about shell development (i.e., what counted as an adequate explanation?), and even why these men, some of the most powerful and influential thinkers and anatomists of their day, were concerned with turtles. By tracing and exposing the context and content of turtle shell studies in history, our aim is to inform modern debates about the evolution and development of the turtle's shell. © 2014 Wiley Periodicals, Inc.

  17. Giambattista Canano and his myology

    Directory of Open Access Journals (Sweden)

    G Štrkalj


    Full Text Available Giambattista Canano was a sixteenth century Italian anatomist and physician. He was educated at the University of Ferrara where, upon graduation, he was appointed professor of anatomy. While at the university, Canano carried out a pioneering study of skeletal muscles. This study was to be published in a multi-volumed book entitled Musculorum Humani Corporis Picturata Dissectio. However, only the section on the muscles of the upper limb was published, as Canano stopped the printing of his book. It is hypothesized that he met Vesalius at the time and saw the proofs of his Fabrica which he assessed as far superior and, consequently, decided to abort his project. The preserved copies of the Dissectio, however, show that the standards of Canano′s work surpassed most of the anatomical studies published up to that time. Canano subsequently left the academic position and made a notable career as a physician. His appointments included prestigious positions of physician to the Pope and protomedicus of the House of Este in Ferrara.

  18. Dissecting through barriers: A mixed-methods study on the effect of interprofessional education in a dissection course with healthcare professional students. (United States)

    Fernandes, Alisha Rebecca; Palombella, Andrew; Salfi, Jenn; Wainman, Bruce


    Healthcare delivery is reliant on a team-based approach, and interprofessional education (IPE) provides a means by which such collaboration skills can be fostered prior to entering the workplace. IPE within healthcare programs has been associated with improved collaborative behavior, patient care and satisfaction, reduced clinical error, and diminished negative professional stereotypes. An intensive interprofessional gross anatomy dissection course was created in 2009 to facilitate IPE at McMaster University. Data were collected from five cohorts over five years to determine the influence of this IPE format on the attitudes and perceptions of students towards other health professions. Each year, 28 students from the medicine, midwifery, nursing, physician's assistant, physiotherapy, and occupational therapy programs were randomly assigned into interprofessional teams for 10 weeks. Sessions involved an anatomy and scope-of-practice presentation, a small-group case-based session, and a dissection. A before/after design measured changes in attitudes and perceptions, while focus group data elaborated on the student experience with the course. Pre- and postmatched data revealed significant improvements in positive professional identity, competency and autonomy, role clarity and attitudes toward other health professions. Qualitative analysis of intraprofessional focus group interviews revealed meaningful improvements in a number of areas including learning anatomy, role clarity, and attitudes towards other health professions. © 2015 American Association of Anatomists.

  19. Mozart's chronic subdural hematoma. (United States)

    Drake, M E


    No commemoration of the bicentennial of Mozart's death would be complete without some consideration of that premature yet predictable demise. Mozart's premonitions of death are well known and apparently played a role in the composition of the K.626 Requiem and perhaps other works. His death has traditionally been ascribed to infectious causes, chiefly rheumatic fever or post-streptococcal glomerulonephritis, exacerbated by intemperance and chronic penury. Pathology has been difficult because of his supposed burial in a pauper's grave, the location and contents of which were later supposedly lost. Mozart's burial place in St. Mark's Cemetery in Vienna was known and, in the parlance of the day, "reorganized" a decade later, as the occupants of plots were disinterred to make room for the more recently decreased. A skull believed to the Mozart's was saved by the successor of the gravedigger who had supervised Mozart's burial, and then passed into the collections of the anatomist Josef Hyrtl, the municipality of Salzburg, and the Mozarteum museum (Salzburg). Forensic reconstruction of soft tissues related to this skull reveals substantial concordance with Mozart's portraits. The skull suggests premature closure of the metopic suture, which has been suggested on the basis of his physiognomy. A left temporal fracture and concomitant erosions raise the question of chronic subdural hematoma, which would be consistent with several falls in 1789 and 1790 and could have caused the weakness, headaches, and fainting he experienced in 1790 and 1791. Aggressive bloodletting to treat suspected rheumatic fever could have decompensated such a lesion to produce his death on December 5, 1791.

  20. Effects of training experienced teachers in the use of the one-minute preceptor technique in the gross anatomy laboratory. (United States)

    Chan, Lap Ki; Sharma, Neel


    The one-minute preceptor (OMP) is a time-efficient, learner-centered teaching method used in a busy ambulatory care setting. This project evaluated the effects of training experienced anatomy teachers in the use of the OMP in the gross anatomy laboratory on students' perceived learning. Second-year medical students from a five-year, undergraduate-entry, system- and problem-based medical program were divided randomly into two groups of 76 students each. The groups took part in the same gross anatomy laboratory session on different dates, supervised by the same two teachers (both with over 25 years of teaching experience). The teachers attended a workshop on the use of the OMP between the two sessions. Students were given a questionnaire at the end of the two sessions to indicate their agreements to statements regarding their learning experiences. Semistructured interviews were conducted with the two teachers after the second session. Results showed that training experienced anatomy teachers in the use of the OMP did not result in improvement of student learning perception in the gross anatomy laboratory. The experienced teachers have developed their own approaches with elements similar to those in the OMP: being learner centered and adaptable to individual student's needs, providing feedback, and enhancing teacher immediacy. They do not have an explicit structure such as the OMP, and are thus flexible and adaptive. Confining the teachers' teaching behaviors to the OMP structure could limit their performance. Although there are theoretical advantages for novice teachers in adopting the OMP technique, these advantages still need to be supported by further studies.

  1. Historical continuity in the methodology of modern medical science: Leonardo leads the way. (United States)

    Pasipoularides, Ares


    Early modern medical science did not arise ex nihilo, but was the culmination of a long history stretching back through the Renaissance, the Middle Ages, Byzantium and Roman times, into Greek Antiquity. The long interval between Aristotle and Galen and Harvey and Descartes was punctuated by outstanding visionaries, including Leonardo, the ultimate Renaissance man. His attitude and mindset were based on Aristotelian pursuit of empirical fact and rational thought. He declared himself to be a "man without letters" to underscore his disdain for those whose culture was only mnemonics and philosophical inferences from authoritative books. Leonardo read the Book of Nature with the immense curiosity of the pioneering scientist, ushering in the methodology of modern medical science with help from forerunners. He left no publications, but extensive personal Notebooks: on his scientific research, hydrodynamics, physiological anatomy, etc. Apparently, numerous successors availed themselves of his methodologies and insights, albeit without attribution. In his Notebooks, disordered and fragmentary, Leonardo manifests the exactitude of the engineer and scientist, the spontaneous freshness of one speaking of what he has at heart and that he knows well. His style is unrefined, but intensely personal, rich with emotion and, sometimes, poetic. Leonardo, the visionary anatomist, strived consistently not merely to imitate nature by depicting body structures, but to perceive through analysis and simulations the intimate physiologic processes; i.e., the biomechanics underlying the workings of all bodily organs and components, even the mysterious beating heart. It is fitting to regard him as the first modern medical scientist. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

  2. "Let's get physical": advantages of a physical model over 3D computer models and textbooks in learning imaging anatomy. (United States)

    Preece, Daniel; Williams, Sarah B; Lam, Richard; Weller, Renate


    Three-dimensional (3D) information plays an important part in medical and veterinary education. Appreciating complex 3D spatial relationships requires a strong foundational understanding of anatomy and mental 3D visualization skills. Novel learning resources have been introduced to anatomy training to achieve this. Objective evaluation of their comparative efficacies remains scarce in the literature. This study developed and evaluated the use of a physical model in demonstrating the complex spatial relationships of the equine foot. It was hypothesized that the newly developed physical model would be more effective for students to learn magnetic resonance imaging (MRI) anatomy of the foot than textbooks or computer-based 3D models. Third year veterinary medicine students were randomly assigned to one of three teaching aid groups (physical model; textbooks; 3D computer model). The comparative efficacies of the three teaching aids were assessed through students' abilities to identify anatomical structures on MR images. Overall mean MRI assessment scores were significantly higher in students utilizing the physical model (86.39%) compared with students using textbooks (62.61%) and the 3D computer model (63.68%) (P < 0.001), with no significant difference between the textbook and 3D computer model groups (P = 0.685). Student feedback was also more positive in the physical model group compared with both the textbook and 3D computer model groups. Our results suggest that physical models may hold a significant advantage over alternative learning resources in enhancing visuospatial and 3D understanding of complex anatomical architecture, and that 3D computer models have significant limitations with regards to 3D learning. © 2013 American Association of Anatomists.

    Full Text Available The communication between the median and ulnar nerves on the forearm, known as the Martin–Gruber anastomosis, is widespread in the general population. Despite the fact that this connection is described by anatomists in XVIII century, its importance has only recently been appreciated because of the widespread of the electrophysiological techniques in clinical practies. However, in the Russian literature aspects of its practical value described so far is not enough. This article deals with the prevalence of the anastomosis, its anatomical and electrophysiological classification, options innervation of muscles of the hand, is carried out through him, described electrophysiological methods and criteria for its diagnosis, including the collision technique, in healthy subjects and patients with lesions of the median and ulnar nerves, given its practical value. Such a course of nerve fibers through this anastomosis can have a significant impact on the clinical manifestations in patients with lesions of the median and ulnar nerves, as well as the results of an electrophysiological study. Martin–Gruber anastomosis provides variability innervation muscles of the hand, which can make it difficult topic diagnostic damage to the median and ulnar nerves, in addition, because of the connection between the nerves of the clinical presentation may not reflect the extent of their defeat: the hand muscles function can be preserved with full nerve damage or, conversely, significantly disrupted with minimal nerve lesions. Moreover, different electrophysiological findings on patients with pathology of the median or ulnar nerves in the conditions of functioning anastomosis may also complicate the interpretation of the clinical data. Thus, knowledge of the anatomy and physiology of the Martin–Gruber communication as necessary for the electrophysiologist for correct interpretation of the finding and the clinician to accurately diagnose the pathology of the median

    Webb, Alexandra Louise; Choi, Sunhea


    A technology enhanced learning and teaching (TELT) solution, radiological anatomy (RA) eLearning, composed of a range of identification-based and guided learning activities related to normal and pathological X-ray images, was devised for the Year 1 nervous and locomotor course at the Faculty of Medicine, University of Southampton. Its effectiveness was evaluated using a questionnaire, pre- and post-tests, focus groups, summative assessment, and tracking data. Since introduced in 2009, a total of 781 students have used RA eLearning, and among them 167 Year 1 students in 2011, of whom 116 participated in the evaluation study. Students enjoyed learning (77%) with RA eLearning, found it was easy to use (81%) and actively engaged them in their learning (75%), all of which were associated to the usability, learning design of the TELT solution and its integration in the curriculum; 80% of students reported RA eLearning helped their revision of anatomy and 69% stated that it facilitated their application of anatomy in a clinical context, both of which were associated with the benefits offered by the learning and activities design. At the end of course summative assessment, student knowledge of RA eLearning relevant topics (mean 80%; SD ±16) was significantly better as compared to topics not relevant to RA eLearning (mean 63%; SD ±15) (mean difference 18%; 95% CI 15% to 20%; P application, integration, and contextualization of anatomy and radiology to create a blended learning environment. © 2013 American Association of Anatomists.

    For centuries, cadaveric dissection has been the touchstone of anatomy education. It offers a medical student intimate access to his or her first patient. In contrast to idealized artisan anatomical models, it presents the natural variation of anatomy in fine detail. However, a new teaching construct has appeared recently in which artificial cadavers are manufactured through three-dimensional (3D) printing of patient specific radiological data sets. In this article, a simple powder based printer is made more versatile to manufacture hard bones, silicone muscles and perfusable blood vessels. The approach involves blending modern approaches (3D printing) with more ancient ones (casting and lost-wax techniques). These anatomically accurate models can augment the approach to anatomy teaching from dissection to synthesis of 3D-printed parts held together with embedded rare earth magnets. Vascular simulation is possible through application of pumps and artificial blood. The resulting arteries and veins can be cannulated and imaged with Doppler ultrasound. In some respects, 3D-printed anatomy is superior to older teaching methods because the parts are cheap, scalable, they can cover the entire age span, they can be both dissected and reassembled and the data files can be printed anywhere in the world and mass produced. Anatomical diversity can be collated as a digital repository and reprinted rather than waiting for the rare variant to appear in the dissection room. It is predicted that 3D printing will revolutionize anatomy when poly-material printing is perfected in the early 21st century. © 2015 American Association of Anatomists.

    Full Text Available La preservación y el mantenimiento de los cadáveres y especímenes anatómicos han llevado a la búsqueda de técnicas diferentes y a la utilización de sustancias distintas al formaldehído con el fin de minimizar los riesgos de exposición a vapores químicos y a agentes biológicos y de disponer de preparados anatómicos con mayor durabilidad, conservando las características anatómicas y facilitando la docencia y la investigación en la disciplina. Una de estas técnicas es la plastinación. Presentamos los resultados obtenidos con ella en la Facultad de Medicina de la Universidad de Antioquia. The preservation and maintenance of anatomical specimens and corpses have created the need for new techniques and for the use of substances different from formaldehyde, in order to lessen the risks of exposure to this substance and to biological agents, and to increase the availability and durability of anatomical pieces preserving their characteristics in order to facilitate teaching and research. In the eighth decade of the XX century the German anatomist von Hagens patented the plastination technique that consists of replacing the water of tissues by silicones, polymers or resins. The plastination process includes four steps: fixation, dehydration, impregnating and curing. There are some difficulties in Colombia regarding the availability of acetone, polymers and silicones as well as a lack of adequate infrastructure for the plastination process; because of this we have modified the technique using other substances at different pressure and temperature conditions; we report the modifications with which we have obtained very good results.

  7. YouTube: An emerging tool in anatomy education. (United States)

    Jaffar, Akram Abood


    The use of online social networks in medical education can remodel and enhance anatomy teaching and learning; one such network is the video-sharing site YouTube. Limited research in the literature exists on the use of YouTube as a platform for anatomy education. The aim of this study is to assess student's perceptions and patterns of usage of this resource, as well as the effectiveness of YouTube videos within a problem-based learning (PBL) curriculum. The study was conducted on 91 second-year medical students for whom video links were suggested throughout the academic year. In addition, the Human Anatomy Education (HAE) Channel was launched on YouTube to support classroom teaching with videos that emphasized applied aspects of anatomy. The results demonstrated that 98% of the students used YouTube as an online information resource, albeit in different frequencies. Out of the 86% who have been to the HAE Channel, 92% agreed/strongly agreed that the channel helped them learn anatomy. The study also reports the popularity of and awareness about using YouTube as a social network as well as in learning. Based on these findings, YouTube can be considered as an effective tool to enhance anatomy instruction if the videos are scrutinized, diversified, and aimed toward course objectives. Faculty of average computer literacy should be enabled to produce videos on their own YouTube channels to support independent learning and integration in a PBL curriculum. The methods described for capturing and editing the videos can be used as a prototype. Copyright © 2012 American Association of Anatomists.

  8. A "do-it-yourself" interactive bone structure module: development and evaluation of an online teaching resource. (United States)

    Rich, Peter; Guy, Richard


    A stand-alone online teaching module was developed to cover an area of musculoskeletal anatomy (structure of bone) found to be difficult by students. The material presented in the module was not formally presented in any other way, thus providing additional time for other curriculum components, but it was assessed in the final examination. The module was developed using "in-house" software designed for academics with minimal computer experience. The efficacy and effectiveness of the module was gauged via student surveys, testing student knowledge before and after module introduction, and analysis of final examination results. At least 74% of the class used the module and student responses were positive regarding module usability (navigation, interaction) and utility (learning support). Learning effectiveness was demonstrated by large significant improvements in the post-presentation test scores for "users" compared with "non-users" and by the percentage of correct responses to relevant multiple choice questions in the final examination. Performance on relevant short answer questions in the final examination was, on average, comparable to that for other components. Though limited by study structure, it was concluded that the module produced learning outcomes equivalent to those generated by more traditional teaching methods. This "Do-It-Yourself" e-learning approach may be particularly useful for meeting specific course needs not catered for by commercial applications or where there are cost limitations for generation of online learning material. The specific approaches used in the study can assist in development of effective online resources in anatomy. Copyright © 2012 American Association of Anatomists.

  9. [Historical development of modern anatomical education in Japan]. (United States)

    Sakai, Tatsuo


    The medical schools in the beginning of Meiji era were diverse both in the founders and in the way of education, frequently employing foreign teachers of various nationalities. In 1871, German teachers were appointed to organized medical education at the medical school of the university of Tokyo. The anatomical education in the school was conducted by German teachers, i.e. Miller (1871-1873), Dönitz (1873-1877), Gierke (1877-1880) and Disse (1880-1885), followed by Koganei who returned from the study in Germany. In 1882 (Meiji 15th), the general rule for medical school was enforced so that the medical schools were practically obliged to employ numbers of graduates of the university of Tokyo. In 1887 (Meiji 20th), the educational system was reformed so that many of the medical schools were closed, and the medical schools were integrated into one university, five national senior high schools and three prefectural ones in addition to four private ones. After that most of anatomical teachers were either graduates of the university of Tokyo or those who studied in the anatomical department of the university. Before 1877 (Meiji 10th), the anatomical books were mainly translated from English books, and foreign teachers of various nationality were employed in many medical schools in Japan. After 1877 (Meiji 10th), the anatomical books based on the lectures by German teachers at the university of Tokyo were published. The anatomical books after 1887 (Meiji 20th) were written based on German books, and the German anatomical terms were utilized. After 1905 (Meiji 38th), the original Japanese anatomical books appeared, employing international anatomical terms. At the first meeting of Japanese Association of Anatomists in 1893 (Meiji 26th), the Japanese anatomical teachers met together and most of them were graduates of the university of Tokyo or fellows of its anatomical department.

  10. The use of limericks to engage student interest and promote active learning in an undergraduate course in functional anatomy. (United States)

    Carnegie, Jacqueline A


    The study of anatomy is a content-dense discipline with a challenging vocabulary. A mnemonic is a series of letters, a word, a phrase, or a rhyme that students can use when studying to facilitate recall. This project was designed to promote active learning in undergraduate students studying anatomy and physiology by asking them to create limericks based on course content and then to evaluate the limericks written by their peers for learning value, accuracy, style, and adherence to limerick characteristics. Students (278 and 288, respectively, in the 2009 and 2010 sections of ANP1107) worked in groups of three to create a total of 242 limericks. Peer evaluation was accomplished in two stages using a 20-point marking rubric. In Stage 1, students were randomly divided into 10 groups (n = 23 ± 2 students) with each group member evaluating the same 12 ± 1 limericks. In Stage 2, the top 19% of limericks were reevaluated by all students so that the best three could be chosen. In each of the two years, 60% of students completed all parts of the assignment. Higher percentages (75-80%) participated in limerick writing and one of the two assessment stages. A positive association was noted between level of student participation in the limerick assignment and final course marks. Limerick creation and evaluation can be used to promote active learning by encouraging students to review functional-anatomy-based content to create limericks with good learning value and to provide valid assessments of limericks written by their peers.

  11. The LINDSAY Virtual Human Project: an immersive approach to anatomy and physiology. (United States)

    Tworek, Janet K; Jamniczky, Heather A; Jacob, Christian; Hallgrímsson, Benedikt; Wright, Bruce


    The increasing number of digital anatomy teaching software packages challenges anatomy educators on how to best integrate these tools for teaching and learning. Realistically, there exists a complex interplay of design, implementation, politics, and learning needs in the development and integration of software for education, each of which may be further amplified by the somewhat siloed roles of programmers, faculty, and students. LINDSAY Presenter is newly designed software that permits faculty and students to model and manipulate three-dimensional anatomy presentations and images, while including embedded quizzes, links, and text-based content. A validated tool measuring impact across pedagogy, resources, interactivity, freedom, granularity, and factors outside the immediate learning event was used in conjunction with observation, field notes, and focus groups to critically examine the impact of attitudes and perceptions of all stakeholders in the early implementation of LINDSAY Presenter before and after a three-week trial period with the software. Results demonstrate that external, personal media usage, along with students' awareness of the need to apply anatomy to clinical professional situations drove expectations of LINDSAY Presenter. A focus on the software over learning, which can be expected during initial orientation, surprisingly remained after three weeks of use. The time-intensive investment required to create learning content is a detractor from user-generated content and may reflect the consumption nature of other forms of digital learning. Early excitement over new technologies needs to be tempered with clear understanding of what learning is afforded, and how these constructively support future application and integration into professional practice.

  12. Georg Büchner, Sigmund Freud and the "Schädelnerven" (cranial nerves) - research on the brain and soul in the 19th century. (United States)

    Hildebrandt, Gerhard; Ruppert, Christina; Stienen, Martin N; Surbeck, Werner


    One of the authors' encounter with one of Sigmund Freud's original works about the anatomy of the human brain stem and his interest in the scientist, anatomist, philosopher, writer and revolutionary Georg Büchner led to re-examination and review of the original writings of two major 19th century protagonists of brain anatomy research. The aim of the authors is to highlight the achievements of both Freud and Büchner in the field of comparative brain morphology. The medical and philosophical publications of Georg Büchner were reviewed with reference to the historical-critical edition of his complete works and writings (the so-called Marburg edition). Evaluation of the neuroanatomical achievements of Sigmund Freud was based on a summary of his publications and also partially on his autobiographical writings. After careful review of their publications both Freud and Büchner should be acknowledged as brain scientists focusing particularly on comparative morphology. Both chose fish as the subject of their macroscopic (Büchner) and microscopic (Freud) neuroanatomical studies, and both cut across their own language and cultural space by continuing their work in France. In interpreting their findings both were influenced by their respective contemporary methodological schools of thought. Büchner became a soul scientist/psychologist by turning to the writing of literary texts, heralding the end of his idealistic and metaphysical interpretation of life. Likewise, Freud increasingly devoted himself to the destiny of man and his "conditio humana," eventually turning away from anatomical brain research. Review of the biographies and medical-scientific, as well as philosophical publications, of Georg Büchner and Sigmund Freud reveal striking parallels between the two researchers in addition to common insights that have generally been ignored or only marginally addressed in the past. Both should be appreciated and remembered as forerunners of today's neuroscientific

  13. [An illustrious unknown. Giuseppe Levi among science, anti-fascism and Nobel Prizes]. (United States)

    Grignolio, Andrea; De Sio, Fabio


    The anatomist Giuseppe Levi (1872-1965) is unanimously considered one of the major figures of Italian biomedical sciences in the 20th century. His fame, however, is mainly derived from having nurtured three Nobel Prize winners, namely Salvador E. Luria, Rita Levi Montalcini and Renato Dulbecco. In reappraising Levi's role in the development of Italian science and culture in general, this article aims at questioning both the narrowness of earlier accounts and a certain kind of genealogical approach to the history of scientific disciplines and academic schools. We will here consider Giuseppe Levi as an instance of two major cultural phenomena: the development of experimental biology in Italy and continental Europe and the anti-fascist socialist culture expressed by a part of the Italian intellectuals. In so doing, we will reassess the historical specificity of the scientific maturation of Levi's three famous students, on the one hand, while on the other we will consider in some depth the cultural and moral environment in which Levi thrived and his role as a moral example for his students. Such revision, we will argue, have a direct bearing on more general historiographical issues, namely, the need for a stronger contextualization of the birth and consolidation of research traditions, implying a rejection of simplistic genealogical reconstructions, and the role of academic schools and institutional settings in the definition of novel, multidisciplinary scientific approaches. Finally, the following will highlight the importance of a more careful outlook on the master-pupil relationship in academic context, addressing issues of both continuity and rupture. The article is subdivided in two main sections, the first devoted to Levi as a scientist, the second to his Anti-fascism.

  14. The Anatomische Gesellschaft and National Socialism - A preliminary analysis based on the society proceedings. (United States)

    Winkelmann, Andreas


    The Anatomische Gesellschaft (AG) is an international society for the anatomical sciences and at the same time the main organising body for German anatomists. This study analyses how the AG went through the years of National Socialism. As the society does not possess archival material from that time, the analysis is mainly based on the society proceedings (Verhandlungen der Anatomischen Gesellschaft) published annually after each meeting from 1934 to 1939 and again in 1950. During the period of National Socialism, the AG kept its international status against demands to make it a purely German society. It did not introduce anti-Jewish regulations or the Führer principle into its bylaws. The membership directories reveal that it was at least possible for members whose career was disrupted by Nazi policies to remain on the membership lists throughout the Nazi period. However, in contrast to later assumptions that no persecuted member of the AG was ever struck from its register, 17 of 57 persecuted members left the society between 1933 and 1939. The membership of six of these members was cancelled, officially for unpaid fees. However, other members with much longer arrears were not cancelled. To date, no additional historical information is available to assess the circumstances of these cancellations. In general, it remains remarkable that, in contrast to many other societies, the AG did not follow the path of preemptive obedience towards the new rulers. More archival sources need to be uncovered to elucidate the external influences and internal negotiations behind the published documents. Copyright © 2012. Published by Elsevier GmbH.

  15. August Hirt and "extraordinary opportunities for cadaver delivery" to anatomical institutes in National Socialism: a murderous change in paradigm. (United States)

    Lang, Hans-Joachim


    German anatomical institutes always had problems obtaining sufficient cadavers for research and training. In the National Socialist (NS) period this changed. Universities could count on "extraordinary opportunities for cadaver delivery." Most frequently tacitly, many bodies were those of victims of NS crimes. Scientists increasingly exploited the exceptional political situation to systematically supplement their institutional collections. Their endeavors to fill the, in their terms, "lamentable gaps" in their collections took on truly bizarre forms. In Austria, Jewish cemeteries were plundered for racial-political expansion of anatomical collections. A change in paradigm was merely the next step: intentional murder for the benefit of NS-oriented science. In December of 1942, anatomists meeting in Tübingen discussed plans for "material acquisition." August Hirt, director of the anatomical institute at the Reichsuniversität in Strasbourg, was to develop guidelines. There was express reference to "Auftrag Beger," which had already been conceived although not yet realized: at the behest of Hirt and the SS-scientific organization, "Ahnenerbe," the anthropologists Bruno Beger and Hans Fleischhacker selected 86 Jewish prisoners in Auschwitz in June of 1943 and deported them to the concentration camp at Struthof near Natzweiler, where they were murdered. The bodies were delivered to the anatomy department in Strasbourg for preparation and used as anatomical specimens. The Reichsuniversität Strasbourg was considered a center of excellence for Nazi ideology. For modern scientists, the elucidation of these criminal acts is not exhausted in the search for an answer to the questions of perpetrator, place, modus operandi or motive. A suitable memorial to the victims must go beyond mere quantification. Copyright © 2013 Elsevier GmbH. All rights reserved.

  16. The Anatomische Gesellschaft and National Socialism: an analysis based on newly available archival material. (United States)

    Winkelmann, Andreas


    The newly available scientific estate of Heinrich von Eggeling (1869-1954), long-time secretary of the Anatomische Gesellschaft (AG), allows a more profound analysis of how this scientific association went through the period of the "Third Reich". At the first meeting under the new rulers in 1934, von Eggeling and Siegfried Mollier prevented their board colleague Martin Heidenhain from giving an introductory talk because they (not unjustly) feared anti-Jewish protests, but also because many anatomy professors, like other German scholars, were fervent nationalists who welcomed Hitler and largely accepted the expulsion of Jewish and other colleagues as 'inevitable' for national renewal. Many persecuted members nevertheless remained on the membership lists and the AG never officially introduced anti-Jewish bylaws. Eggeling and his like-minded colleagues successfully defended the international status of the AG, though not so much against the Nazi authorities but against a younger generation of anatomists who were willing to benefit from the new political situation and strived for their own German anatomical association. The available archival material suggests that the motivation of the established leading members of the AG to take this specific path was not rooted in opposition to the new rulers but rather in defence of their traditional status of reputed professors running a time-honoured, world leading society. This made international reputation an important guideline for many decisions. While they did ward off attempts by the younger generation to politicise the AG, their post-war calls for an apolitical science remain ambivalent, as their own stance had not always been apolitical.

  17. Teaching the Anatomy of Oncology: Evaluating the Impact of a Dedicated Oncoanatomy Course

    International Nuclear Information System (INIS)

    Chino, Junzo P.; Lee, W. Robert; Madden, Richard; Sims, Ershela L.; Kivell, Tracy L.; Doyle, Sara K.; Mitchell, Terry L.; Hoppenworth, E. Jane; Marks, Lawrence B.


    Purpose: Anatomic considerations are often critical in multidisciplinary cancer care. We developed an anatomy-focused educational program for radiation oncology residents integrating cadaver dissection into the didactic review of diagnostic, surgical, radiologic, and treatment planning, and herein assess its efficacy. Methods and Materials: Monthly, anatomic-site based educational modules were designed and implemented during the 2008-2009 academic year at Duke University Medical Center. Ten radiation oncology residents participated in these modules consisting of a 1-hour didactic introduction followed by a 1-hour session in the gross anatomy lab with cadavers prepared by trained anatomists. Pretests and posttests were given for six modules, and post-module feedback surveys were distributed. Additional review questions testing knowledge from prior sessions were integrated into the later testing to evaluate knowledge retention. Paired analyses of pretests and postests were performed by Wilcoxon signed-rank test. Results: Ninety tests were collected and scored with 35 evaluable pretest and posttest pairs for six site-specific sessions. Posttests had significantly higher scores (median percentage correct 66% vs. 85%, p < 0.001). Of 47 evaluable paired pretest and review questions given 1-3 months after the intervention, correct responses rates were significantly higher for the later (59% vs. 86%, p = 0.008). Resident course satisfaction was high, with a median rating of 9 of 10 (IQR 8-9); with 1 being 'less effective than most educational interventions' and 10 being 'more effective than most educational interventions.' Conclusions: An integrated oncoanatomy course is associated with improved scores on post-intervention tests, sustained knowledge retention, and high resident satisfaction.

  18. Constructive, collaborative, contextual, and self-directed learning in surface anatomy education. (United States)

    Bergman, Esther M; Sieben, Judith M; Smailbegovic, Ida; de Bruin, Anique B H; Scherpbier, Albert J J A; van der Vleuten, Cees P M


    Anatomy education often consists of a combination of lectures and laboratory sessions, the latter frequently including surface anatomy. Studying surface anatomy enables students to elaborate on their knowledge of the cadaver's static anatomy by enabling the visualization of structures, especially those of the musculoskeletal system, move and function in a living human being. A recent development in teaching methods for surface anatomy is body painting, which several studies suggest increases both student motivation and knowledge acquisition. This article focuses on a teaching approach and is a translational contribution to existing literature. In line with best evidence medical education, the aim of this article is twofold: to briefly inform teachers about constructivist learning theory and elaborate on the principles of constructive, collaborative, contextual, and self-directed learning; and to provide teachers with an example of how to implement these learning principles to change the approach to teaching surface anatomy. Student evaluations of this new approach demonstrate that the application of these learning principles leads to higher student satisfaction. However, research suggests that even better results could be achieved by further adjustments in the application of contextual and self-directed learning principles. Successful implementation and guidance of peer physical examination is crucial for the described approach, but research shows that other options, like using life models, seem to work equally well. Future research on surface anatomy should focus on increasing the students' ability to apply anatomical knowledge and defining the setting in which certain teaching methods and approaches have a positive effect.

  19. Does learning in clinical context in anatomical sciences improve examination results, learning motivation, or learning orientation? (United States)

    Böckers, Anja; Mayer, Christian; Böckers, Tobias Maria


    The preclinical compulsory elective course "Ready for the Operating Room (OR)!?" [in German]: "Fit für den OP (FOP)"] was implemented for students in their second year, who were simultaneously enrolled in the gross anatomy course. The objective of the study was to determine whether the direct practical application of anatomical knowledge within the surgical context of the course led to any improvement in learning motivation, learning orientation, and ultimately examination results in the gross anatomy course, as compared with a control group. Within the scope of five teaching sessions, the students learned surgical hand disinfection, suturing techniques, and the identification of commonly used surgical instruments. In addition, the students attended five surgical demonstrations performed by surgical colleagues on cadavers. Successful learning of these basic skills was then assessed based on an Objectively Structured Practical Examination. Learning motivation and learning orientation in both subgroups was determined using the SELLMO-ST motivation test and the Approaches and Study Skills Inventory test. While a significant increase in work avoidance was identified in the control group, this was not the case for FOP participants. Similarly, an increase in the "deep approach" to learning, as well as a decrease in the "surface approach," was able to be documented among the FOP participants following completion of the course. The results suggest that students enrolled in the gross anatomy course, who were simultaneously provided with the opportunity to learn in clinical context, were more likely to be successful at maintaining learning motivation and learning orientation required for the learning process, than students who attended the gross anatomy course alone. © 2013 American Association of Anatomists.

    Medical education in Ottoman-Turkish medicine was shaped by the influence of Claudius Galenus (c.130-c.210) and Ibn-i Sina (c.980-c.1037). These teachings were performed in madrasahs until the beginning of the 19th century period. Within the scope of master-apprentice relationship, medical training was also given in private clinics. As a result of religious and social pressures on scientific studies human cadavers were never used because they were considered sacred. For centuries, all books were handwritten during the Ottoman Empire until the first printing press was established in Istanbul during 1726. However, the first illustrated book on anatomy was not printed until another 100 years later. A comparative study was conducted on the anatomical drawings in"Miratü'l Ebdan Fi Teşrih-i Azau'l İnsan" (Ataullah ŞM, 17th),and significance of this book. 46 out of 56 figures were received from the book of physian and anatomist Jean Palfin (1650-1730). Remaining 9 figures were cited from author himself as collected from Bernard Siegfried Albinus (1697-1170), Raymond Vieussens (1614- 1715), R. Drake (1667-1707), Clopton Havers (1657-1702), Albrecht von Haller (1708- 1777), Joseph Guichard Duverney (1648-1730). The figures were drawn exactly the same way with minimal changes. Main text of the book is mostly translation from Italian edition of Bertin and Palfin's Works.The book is not only the first printed anatomical book but also the first printed work in Ottoman-Turkish medicine. Another very significant aspect is the illustrations are perspective drawing figures which differs from miniature style drawings of the past. Şânîzade Ataullah's work is a significant value not only for being the first printed illustrated anatomy book which makes it more approachable but also gives anatomical drawings as illustrations not as miniature style painting.

  1. Art, anatomy, and medicine: Is there a place for art in medical education? (United States)

    Bell, Lawrence T O; Evans, Darrell J R


    For many years art, anatomy and medicine have shared a close relationship, as demonstrated by Leonardo da Vinci's anatomical drawings and Andreas Vesalius' groundbreaking illustrated anatomical textbook from the 16th century. However, in the modern day, can art truly play an important role in medical education? Studies have suggested that art can be utilized to teach observational skills in medical students, a skill that is integral to patient examination but seldom taught directly within medical curricula. This article is a subjective survey that evaluates a student selected component (SSC) that explored the uses of art in medicine and investigates student perception on the relationship between the two. It also investigates whether these medical students believe that art can play a role in medical education, and more specifically whether analyzing art can play a role in developing observational skills in clinicians. An "Art in Medicine" 8-week course was delivered to first year medical students at Brighton and Sussex Medical School. The use of art to improve observational skills was a core theme throughout. Feedback from the students suggests that they believe a strong association between art and medicine exists. It also showed a strong perception that art could play a role in medical education, and more specifically through analyzing art to positively develop clinical observational skills. The results of this subjective study, together with those from research from elsewhere, suggest that an art-based approach to teaching observational skills may be worth serious consideration for inclusion in medical and other healthcare curricula. © 2014 American Association of Anatomists.

    Full Text Available BACKGROUND Knowledge of coronary artery branching pattern and their anomalies that occur during foetal development is essential for clinicians. They are associated with high incidence of morbidity and mortality due to congenital heart diseases. Failure to recognise them can lead to inadequate or prolonged procedures and may also lead to misdiagnosis and complications such as accidental ligation. MATERIALS AND METHODS A properly embalmed and stored 50 human heart specimens were dissected in the age group of 20-65 years to study the course and distribution of coronary arteries. The study was conducted in dissection hall, Department of Anatomy, Rajah Muthiah Medial College and Hospital (RMMC and H, Annamalai University, Chidambaram, Tamil Nadu, India, from August 2010 to July 2013. RESULTS We found a very rare incidence of anomalous branching pattern in the coronary circulation out of 50 heart specimens. The anterior interventricular artery was found giving off one communicating branch to Right Coronary Artery (RCA on the anterior aspect of infundibulum, which after taking sinuous course to join RCA. We coined this anomalous communication as arteria anastomotica infundibularis magna. To our knowledge, this is a very rare incidence and it is not reported elsewhere. CONCLUSION Due to excessive stress and strain of day-to-day modern life, the incidence of death due to myocardial ischaemia also increases. To treat medically and surgically, the basic knowledge of the coronary arteries and its branching pattern with any anomalous is essential for cardiologists, cardiothoracic surgeons, radiologists and especially anatomists for teaching of undergraduate and postgraduate students of anatomy.

  3. Henry Solomon Wellcome: A philanthropist and a pioneer sponsor of medical research in the Sudan. (United States)

    Adeel, Ahmed Awad A


    Henry Solomon Wellcome, the famous drug manufacturer had a fascinating association with the Sudan. Besides supporting tropical medicine research in this country, he established an extensive project in the Sudan that aimed at combining archeological excavations, philanthropy and social reform. This article is an archives-based account on this side of Wellcome's association with the Sudan. The article starts with Wellcome's early years in the American Midwest and the evolution of his career and his rise as a world-renowned drug manufacturer. After the battle of Omdurman, Wellcome visited Sudan in 1900 - 1901 where he offered to support the establishment of the research laboratories which later came to be known as the Wellcome Tropical Research Laboratories in Khartoum. He then became directly involved in the planning and running of extensive archeological excavations in the central Sudan. This project served as a field in which Wellcome found an outlet for his philanthropy. More than 4000 labourers were employed in Jebel Moya. Professional archeologists and anatomists were recruited by Wellcome to supervise the work, and all the requirements in terms of equipment were catered for. Wellcome devised a Savings Bank System whereby part of the earnings of each labourer were saved to him till the end of the season. He also introduced one of his innovations: aerial photography using box kite which was used for the first time in archeology. Wellcome made it a rule that no applicant should be turned away. The Camp Commandant had to find suitable work for each applicant, including the handicapped who were assigned to appropriate jobs like mending baskets or cutting grass for building huts. Wellcome's welfare work had a significant impact on the local inhabitants of Jebel Moya. Henry Solomon Wellcome, 1906. Oil painting by Hugh Goldwin Riviere. Credit: Wellcome Library.

  4. Muscle Logic: New Knowledge Resource for Anatomy Enables Comprehensive Searches of the Literature on the Feeding Muscles of Mammals.

    Directory of Open Access Journals (Sweden)

    Robert E Druzinsky

    Full Text Available In recent years large bibliographic databases have made much of the published literature of biology available for searches. However, the capabilities of the search engines integrated into these databases for text-based bibliographic searches are limited. To enable searches that deliver the results expected by comparative anatomists, an underlying logical structure known as an ontology is required.Here we present the Mammalian Feeding Muscle Ontology (MFMO, a multi-species ontology focused on anatomical structures that participate in feeding and other oral/pharyngeal behaviors. A unique feature of the MFMO is that a simple, computable, definition of each muscle, which includes its attachments and innervation, is true across mammals. This construction mirrors the logical foundation of comparative anatomy and permits searches using language familiar to biologists. Further, it provides a template for muscles that will be useful in extending any anatomy ontology. The MFMO is developed to support the Feeding Experiments End-User Database Project (FEED,, a publicly-available, online repository for physiological data collected from in vivo studies of feeding (e.g., mastication, biting, swallowing in mammals. Currently the MFMO is integrated into FEED and also into two literature-specific implementations of Textpresso, a text-mining system that facilitates powerful searches of a corpus of scientific publications. We evaluate the MFMO by asking questions that test the ability of the ontology to return appropriate answers (competency questions. We compare the results of queries of the MFMO to results from similar searches in PubMed and Google Scholar.Our tests demonstrate that the MFMO is competent to answer queries formed in the common language of comparative anatomy, but PubMed and Google Scholar are not. Overall, our results show that by incorporating anatomical ontologies into searches, an expanded and anatomically comprehensive

  5. @AACAnatomy twitter account goes live: A sustainable social media model for professional societies. (United States)

    Benjamin, Hannah K; Royer, Danielle F


    Social media, with its capabilities of fast, global information sharing, provides a useful medium for professional development, connecting and collaborating with peers, and outreach. The goals of this study were to describe a new, sustainable model for Twitter use by professional societies, and analyze its impact on @AACAnatomy, the Twitter account of the American Association of Clinical Anatomists. Under supervision of an Association committee member, an anatomy graduate student developed a protocol for publishing daily tweets for @AACAnatomy. Five tweet categories were used: Research, Announcements, Replies, Engagement, and Community. Analytics from the 6-month pilot phase were used to assess the impact of the new model. @AACAnatomy had a steady average growth of 33 new followers per month, with less than 10% likely representing Association members. Research tweets, based on Clinical Anatomy articles with an abstract link, were the most shared, averaging 5,451 impressions, 31 link clicks, and nine #ClinAnat hashtag clicks per month. However, tweets from non-Research categories accounted for the highest impression and engagement metrics in four out of six months. For all tweet categories, monthly averages show consistent interaction of followers with the account. Daily tweet publication resulted in a 103% follower increase. An active Twitter account successfully facilitated regular engagement with @AACAnatomy followers and the promotion of clinical anatomy topics within a broad community. This Twitter model has the potential for implementation by other societies as a sustainable medium for outreach, networking, collaboration, and member engagement. Clin.

  6. The public display of plastinates as a challenge to the integrity of anatomy. (United States)

    Jones, David Gareth


    Anatomy has been thrust into the public domain by the highly successful public displays of dissected and plastinated human bodies. This is anatomy in modern guise, anatomy as perceived by the general public. If this is the case, the message it is giving the public about the nature of anatomy is that it is an impersonal analysis of the human body of value within a medical and health care environment. While this is in part true, and while it reflects important aspects of anatomy's history, it fails to reflect the humanistic strands within an increasing swathe of contemporary anatomy. These are manifested in growing recognition of the centrality of informed consent in the practice of anatomy, awareness of the personal dimensions and relationships of those whose bodies are being dissected, and manifested in thanksgiving ceremonies involving staff and students. The notion that the bodies undergoing dissection can be students' first teachers and/or patients is gaining ground, another indication of the human dimensions of the anatomical enterprise. Exhibitions such as Body Worlds ignore these dimensions within anatomy by dislocating it from its clinical and relational base. The significance of this is that loss of these dimensions leads to a loss of the human face of anatomy by isolating it from the people whose body bequests made this knowledge possible. What is required is greater transparency and openness in the practices of all who deal with the dead human body, trends that owe much to the writings of scholars from within a range of humanities disciplines as they have responded to the public displays of dissected plastinated bodies. Anatomists have much to learn from these debates. © 2015 Wiley Periodicals, Inc.

  7. A 3D high resolution ex vivo white matter atlas of the common squirrel monkey (Saimiri sciureus) based on diffusion tensor imaging. (United States)

    Gao, Yurui; Parvathaneni, Prasanna; Schilling, Kurt G; Wang, Feng; Stepniewska, Iwona; Xu, Zhoubing; Choe, Ann S; Ding, Zhaohua; Gore, John C; Chen, Li Min; Landman, Bennett A; Anderson, Adam W


    Modern magnetic resonance imaging (MRI) brain atlases are high quality 3-D volumes with specific structures labeled in the volume. Atlases are essential in providing a common space for interpretation of results across studies, for anatomical education, and providing quantitative image-based navigation. Extensive work has been devoted to atlas construction for humans, macaque, and several non-primate species (e.g., rat). One notable gap in the literature is the common squirrel monkey - for which the primary published atlases date from the 1960's. The common squirrel monkey has been used extensively as surrogate for humans in biomedical studies, given its anatomical neuro-system similarities and practical considerations. This work describes the continued development of a multi-modal MRI atlas for the common squirrel monkey, for which a structural imaging space and gray matter parcels have been previously constructed. This study adds white matter tracts to the atlas. The new atlas includes 49 white matter (WM) tracts, defined using diffusion tensor imaging (DTI) in three animals and combines these data to define the anatomical locations of these tracks in a standardized coordinate system compatible with previous development. An anatomist reviewed the resulting tracts and the inter-animal reproducibility (i.e., the Dice index of each WM parcel across animals in common space) was assessed. The Dice indices range from 0.05 to 0.80 due to differences of local registration quality and the variation of WM tract position across individuals. However, the combined WM labels from the 3 animals represent the general locations of WM parcels, adding basic connectivity information to the atlas.

  8. The history of hysteria and what’s next…

    Directory of Open Access Journals (Sweden)

    Hłodzik Klemens


    Full Text Available From the ancient times up till now hysteria has been a mysterious and intriguing issue. The authors of this article using mainly the work of Etienne Trillat of the same title, present the most important facts from the history of hysteria. Our work shows how notions of hysteria known initially as uterine dyspnoea, which was the term used by Hippocrates in the seventh tome of his “Collected Works” evolved step by step. At the end of 1st century AD a newcomer to Rome, Soranus of Ephesus, as an experienced anatomist in his “Treatise on midwifery and the diseases of women” moved away from the old ideas of Plato and Hippocrates equating uterus to an animal. How did views on hysteria develop throughout Middle Ages, Renaissance or World Wars period? In this article the authors are trying to determine the nature of hysteria as well as what remained from hysteria in the contemporary times, depicting hysteria’s elusiveness as a disease, many difficulties with its definition and connection with many shocking events in history of mankind. From the ancient sages, through Kramer, Sprenger, Wier, Harvey, Willis, Sydenham, Blackmore up until Mesmer, Freud and many others. From hysteric witches, beings suffering from vapors, through sensitive, fragile and musing women up until mythomaniacs, nymphomaniacs and what we define today as histrionic personality disorder. In the words of French neurologist and a creator of psychiatry – Charcot – hysteria existed forever, everywhere and all-time. Why did it vanish though? Authors of this article will address this problem in the final part, trying to determine the cause.

  9. On the origin of Ammon's horn. (United States)

    Iniesta, I


    Greek and Roman worship of their gods and myths go back to Ancient Egyptian times. Images engraved in Greco-Roman coinage range from references to the assassination of Caesar and legendary stories like the arrival of a snake shaped demi-god Aesculapius to save the Romans from the plague, to invocations of major deities including Apollo the physician or Ammon the protector. Depicted with the horns of a ram, Ammon was adopted by the Greeks as an epithet of Zeus and later incorporated by the Romans as Jupiter. References to the cult of Ammon appear on tetradrachms minted for Alexander The Great and on provincial Roman coins struck under Claudius. It is thrilling to hold a coin depicting Marcus Aurelius with Salus on the reverse and think that it could have been handed to Galen in payment for his services. However, it is rare to find figures other than rulers on coins and the physician of Pergamum is no exception. Inspired by the Renaissance school of Padua, French anatomists in the Enlightenment (Garengeot in 1742 and Flurant in 1752) continued reviving ancient myths and named the curve-shaped-inner portion of the temporal lobe Ammon's horn. Outstanding scholars who studied this primitive structure of the brain included Lorente de Nó and his mentor Cajal, whose portrait appeared on fifty-pesetas notes issued in 1935. As primary sources of great archaeological and artistic value, Greco-Roman coins provide information about the origins of the myths and gods of classical antiquity and continue to inspire the arts and sciences to this day.

  10. Effectiveness and Complications of Percutaneous Needle Tenotomy with a Large Needle for Muscle Contractures: A Cadaver Study.

    Directory of Open Access Journals (Sweden)

    Camille Chesnel

    Full Text Available Twenty-two percent of institutionalised elderly persons have muscle contractures. Contractures have important functional consequences, rendering hygiene and positioning in bed or in a chair difficult. Medical treatment (such as botulinum toxin injections, physiotherapy or positioning is not very effective and surgery may be required. Surgery is carried out in the operating theatre, under local or general anaesthesia but is often not possible in fragile patients. Mini-invasive tenotomy could be a useful alternative as it can be carried out in ambulatory care, under local anaesthesia.To evaluate the effectiveness of percutaneous needle tenotomy and the risks of damage to adjacent structures in cadavers.Thirty two doctors who had never practiced the technique (physical medicine and rehabilitation specialists, geriatricians and orthopaedic surgeons carried out 401 tenotomies on the upper and lower limbs of 8 fresh cadavers. A 16G needle was used percutaneous following location of the tendons. After each tenotomy, a neuro-orthopaedic surgeon and an anatomist dissected the area in order to evaluate the success of the tenotomy and any adjacent lesions which had occurred.Of the 401 tenotomies, 72% were complete, 24.9% partial and 2.7% failed. Eight adjacent lesions occurred (2%: 4 (1% in tendons or muscles, 3 (0.7% in nerves and 1 (0.2% in a vessel.This percutaneous needle technique effectively ruptured the desired tendons, with few injuries to adjacent structures. Although this study was carried out on cadavers, the results suggest it is safe to carry out on patients.

  11. Neural systems language: a formal modeling language for the systematic description, unambiguous communication, and automated digital curation of neural connectivity. (United States)

    Brown, Ramsay A; Swanson, Larry W


    Systematic description and the unambiguous communication of findings and models remain among the unresolved fundamental challenges in systems neuroscience. No common descriptive frameworks exist to describe systematically the connective architecture of the nervous system, even at the grossest level of observation. Furthermore, the accelerating volume of novel data generated on neural connectivity outpaces the rate at which this data is curated into neuroinformatics databases to synthesize digitally systems-level insights from disjointed reports and observations. To help address these challenges, we propose the Neural Systems Language (NSyL). NSyL is a modeling language to be used by investigators to encode and communicate systematically reports of neural connectivity from neuroanatomy and brain imaging. NSyL engenders systematic description and communication of connectivity irrespective of the animal taxon described, experimental or observational technique implemented, or nomenclature referenced. As a language, NSyL is internally consistent, concise, and comprehensible to both humans and computers. NSyL is a promising development for systematizing the representation of neural architecture, effectively managing the increasing volume of data on neural connectivity and streamlining systems neuroscience research. Here we present similar precedent systems, how NSyL extends existing frameworks, and the reasoning behind NSyL's development. We explore NSyL's potential for balancing robustness and consistency in representation by encoding previously reported assertions of connectivity from the literature as examples. Finally, we propose and discuss the implications of a framework for how NSyL will be digitally implemented in the future to streamline curation of experimental results and bridge the gaps among anatomists, imagers, and neuroinformatics databases.

  12. Assessment of Thiel-Embalmed Cadavers as a Teaching Tool for Oral Anatomy and Local Anesthesia. (United States)

    Lone, Mutahira; McKenna, Joseph P; Balta, Joy Y; O'Mahony, Siobhain M; Cryan, John F; Downer, Eric J; Toulouse, André


    The aim of this study was to determine whether Thiel-embalmed cadavers would provide a useful anatomy teaching tool for topics that cannot be approached using formalin-fixed cadavers such as oral cavity examination and maxillary anesthesia. The suitability of Thiel-embalmed bodies for performing oral examinations was assessed by asking first-year dental and dental hygiene students at a dental school in Ireland to identify oral structures on a classmate and on a Thiel-embalmed body. The study was conducted in 2016. The ease of location was compared in the two settings, and their quality was assessed on the cadavers. The suitability of Thiel-embalmed cadavers to teach maxillary anesthesia was assessed by students' performing mock injections at five adjacent sites daily for five consecutive days, followed by inspection of the gingival surface by experienced anatomists and dentists. Data were obtained from 57 students, but only the 54 forms that were fully completed were analyzed, for an overall response rate of 85.7%. The results showed that most oral structures were more difficult to locate on cadavers. The texture and appearance of features in the cadavers were rated at a midpoint between realistic and unrealistic. The relative inexperience of the participants, the accumulation of fixative in the oral cavity, and discoloration were mentioned as potential confounding factors. Visual analysis of images obtained following repeated injections revealed no deterioration of the tissue. Importantly, the puncture marks appeared to reduce over time, suggesting that the gingival tissue maintains some elasticity following Thiel fixation. These findings suggest that Thiel-embalmed cadavers may be a useful tool to provide students more time to localize and study aspects of the oral cavity. Likewise, the recoiling capacity of gingival tissue suggests that Thiel-embalmed cadavers may provide an ideal tool for teaching injection technique of local anesthetics.

  13. The implementation of clay modeling and rat dissection into the human anatomy and physiology curriculum of a large urban community college. (United States)

    Haspel, Carol; Motoike, Howard K; Lenchner, Erez


    After a considerable amount of research and experimentation, cat dissection was replaced with rat dissection and clay modeling in the human anatomy and physiology laboratory curricula at La Guardia Community College (LAGCC), a large urban community college of the City University of New York (CUNY). This article describes the challenges faculty overcame and the techniques used to solve them. Methods involved were: developing a laboratory manual in conjunction with the publisher, holding training sessions for faculty and staff, the development of instructional outlines for students and lesson plans for faculty, the installation of storage facilities to hold mannequins instead of cat specimens, and designing mannequin clean-up techniques that could be used by more than one thousand students each semester. The effectiveness of these curricular changes was assessed by examining student muscle practical examination grades and the responses of faculty and students to questionnaires. The results demonstrated that the majority of faculty felt prepared to teach using clay modeling and believed the activity was effective in presenting lesson content. Students undertaking clay modeling had significantly higher muscle practical examination grades than students undertaking cat dissection, and the majority of students believed that clay modeling was an effective technique to learn human skeletal, respiratory, and cardiovascular anatomy, which included the names and locations of blood vessels. Furthermore, the majority of students felt that rat dissection helped them learn nervous, digestive, urinary, and reproductive system anatomy. Faculty experience at LAGCC may serve as a resource to other academic institutions developing new curricula for large, on-going courses. © 2013 American Association of Anatomists.

  14. Historical development of modern anatomy education in Japan. (United States)

    Sakai, Tatsuo


    Medical schools at the beginning of Meiji era were diverse, both in regard to their founders and their methods of education, frequently employing foreign teachers of various nationalities. In 1871, German teachers were appointed to organize medical education at the medical school of the University of Tokyo. The anatomical education at the school was conducted by German teachers, i.e. Miller (1871-1873), Dönitz (1873-1877), Gierke (1877-1880) and Disse (1880-1885), followed by Koganei, who returned from the study in Germany. At the first meeting of Japanese Association ofAnatomists in 1893 [Meiji 26], the Japanese anatomy teachers met together and most of them were graduates of the University of Tokyo or fellows of its anatomy department. Before 1877 [Meiji 10], the anatomy books were mainly translated from English books, and foreign teachers of various nationalities were employed in many medical schools in Japan. After 1877 [Meiji 10], the anatomy books based on the lectures by German teachers at the University of Tokyo were published. The anatomy books after 1887 [Meiji 20] were written based on German books, and the German anatomical terms were utilized. After 1905 [Meiji 38], the original Japanese anatomy books appeared, employing international anatomical terms. In the Meiji 10s the anatomy teachers and anatomy textbooks spread from the University of Tokyo to the medical schools in Japan as the number of medical schools increased temporally. In the Meiji 20s the five national and three public medical schools in addition to the University of Tokyo provided substantial anatomy education including dissection course. Even in the early Meiji 20s these medical schools supplied only half of the newly licensed doctors, and the others were supplied through the national examination after preparatory education at private medical schools without opportunity of substantial anatomy education including dissection course.

  15. Actual drawing of histological images improves knowledge retention. (United States)

    Balemans, Monique C M; Kooloos, Jan G M; Donders, A Rogier T; Van der Zee, Catharina E E M


    Medical students have to process a large amount of information during the first years of their study, which has to be retained over long periods of nonuse. Therefore, it would be beneficial when knowledge is gained in a way that promotes long-term retention. Paper-and-pencil drawings for the uptake of form-function relationships of basic tissues has been a teaching tool for a long time, but now seems to be redundant with virtual microscopy on computer-screens and printers everywhere. Several studies claimed that, apart from learning from pictures, actual drawing of images significantly improved knowledge retention. However, these studies applied only immediate post-tests. We investigated the effects of actual drawing of histological images, using randomized cross-over design and different retention periods. The first part of the study concerned esophageal and tracheal epithelium, with 384 medical and biomedical sciences students randomly assigned to either the drawing or the nondrawing group. For the second part of the study, concerning heart muscle cells, students from the previous drawing group were now assigned to the nondrawing group and vice versa. One, four, and six weeks after the experimental intervention, the students were given a free recall test and a questionnaire or drawing exercise, to determine the amount of knowledge retention. The data from this study showed that knowledge retention was significantly improved in the drawing groups compared with the nondrawing groups, even after four or six weeks. This suggests that actual drawing of histological images can be used as a tool to improve long-term knowledge retention. © 2015 American Association of Anatomists.

  16. Estimation of Stature from Footprint Anthropometry Using Regression Analysis: A Study on the Bidayuh Population of East Malaysia

    Directory of Open Access Journals (Sweden)

    T. Nataraja Moorthy


    Full Text Available The human foot has been studied for a variety of reasons, i.e., for forensic as well as non-forensic purposes by anatomists, forensic scientists, anthropologists, physicians, podiatrists, and numerous other groups. An aspect of human identification that has received scant attention from forensic anthropologists is the study of human feet and the footprints made by the feet. The present study, conducted during 2013-2014, aimed to derive population specific regression equations to estimate stature from the footprint anthropometry of indigenous adult Bidayuhs in the east of Malaysia. The study sample consisted of 480 bilateral footprints collected using a footprint kit from 240 Bidayuhs (120 males and 120 females, who consented to taking part in the study. Their ages ranged from 18 to 70 years. Stature was measured using a portable body meter device (SECA model 206. The data were analyzed using PASW Statistics version 20. In this investigation, better results were obtained in terms of correlation coefficient (R between stature and various footprint measurements and regression analysis in estimating the stature. The (R values showed a positive and statistically significant (p < 0.001 relationship between the two parameters. The correlation coefficients in the pooled sample (0.861–0.882 were comparatively higher than those of an individual male (0.762-0.795 and female (0.722-0.765. This study provided regression equations to estimate stature from footprints in the Bidayuh population. The result showed that the regression equations without sex indicators performed significantly better than models with gender indications. The regression equations derived for a pooled sample can be used to estimate stature, even when the sex of the footprint is unknown, as in real crime scenes.

Entre as propriedades físicas que conferem qualidade às madeiras identificadas, destaca-se a densidade básica, com valores médios a altos em sua maioria, indicando seu uso potencial em elementos com função estrutural. Dentre as possíveis interpretações, os resultados evidenciam o uso de madeiras para a construção de uma plataforma projetada para dar sustentação ao sítio, possivelmente em função das características plásticas dos solos de manguezal.

  18. The CREST Simulation Development Process: Training the Next Generation. (United States)

    Sweet, Robert M


    The challenges of training and assessing endourologic skill have driven the development of new training systems. The Center for Research in Education and Simulation Technologies (CREST) has developed a team and a methodology to facilitate this development process. Backwards design principles were applied. A panel of experts first defined desired clinical and educational outcomes. Outcomes were subsequently linked to learning objectives. Gross task deconstruction was performed, and the primary domain was classified as primarily involving decision-making, psychomotor skill, or communication. A more detailed cognitive task analysis was performed to elicit and prioritize relevant anatomy/tissues, metrics, and errors. Reference anatomy was created using a digital anatomist and clinician working off of a clinical data set. Three dimensional printing can facilitate this process. When possible, synthetic or virtual tissue behavior and textures were recreated using data derived from human tissue. Embedded sensors/markers and/or computer-based systems were used to facilitate the collection of objective metrics. A learning Verification and validation occurred throughout the engineering development process. Nine endourology-relevant training systems were created by CREST with this approach. Systems include basic laparoscopic skills (BLUS), vesicourethral anastomosis, pyeloplasty, cystoscopic procedures, stent placement, rigid and flexible ureteroscopy, GreenLight PVP (GL Sim), Percutaneous access with C-arm (CAT), Nephrolithotomy (NLM), and a vascular injury model. Mixed modalities have been used, including "smart" physical models, virtual reality, augmented reality, and video. Substantial validity evidence for training and assessment has been collected on systems. An open source manikin-based modular platform is under development by CREST with the Department of Defense that will unify these and other commercial task trainers through the common physiology engine, learning

  19. ["Fiction and Truth": Goethe's anatomical research at the University of Jena]. (United States)

    Schäfer, H H; Sivukhina, E; Dölz, W; Oehring, H


    Johann Wolfgang von Goethe was one of the most renowned German poets of the late Age of Enlightenment. However, his engagement went far beyond literature especially relating to politics and natural science. Goethe, primarily trained as a lawyer, developed his own theory of colors and even challenged the concepts of Isaac Newton. His discovery of the human intermaxilary bone questioned all the dogmas of the religious-minded world of the 18th century. Together with the anatomy professor Justus Christian Loder, Goethe performed comparative anatomy and proved the conceptual uniformity of humans and animals on 27 March 1784. Even though, Félix Vicq d'Azyr described the intermaxilary bone simultaneously in Catholic France, Goethe's findings were politically accepted due to the liberal Protestantism of the Duchy of Weimar. Nevertheless, leading anatomists of the century (Johann Friedrich Blumenbach, Petrus Camper and Samuel Thomas v. Soemmerring) mainly rejected Goethe's postulates which led to a delayed publication in 1820; almost 36 years after writing his original manuscript. Today, Goethe's discovery is known to be a fundamental basis for the development of Charles Darwin's theory of phylogenetic evolution. Nowadays, the Department of Anatomy contains the Museum Anatomicum Jenense which was founded by the Duke of Weimar, Carl August and Goethe and entails Goethe's premaxillary bones as its main attraction. The University values the cultural heritage of Goethe's contribution to Medicine and provides access to the collection to the public and generations of medical students. Still today Goethe's legacy is noticeable in the halls of the Alma Mater Jenensis. © Georg Thieme Verlag KG Stuttgart · New York.

    Grković, Ivica; Marinović Guić, Maja; Košta, Vana; Poljičanin, Ana; Čarić, Ana; Vilović, Katarina


    Aim To evaluate the structure of the anatomy program in the first year medical curriculum of University of Split School of Medicine by comparing it with the recommendations by the Educational Affairs Committee of the American Association of Clinical Anatomists (AACA) and the Terminologia Anatomica (TA); we also quantitatively evaluated the organization of teaching material in contemporary topographical anatomy textbooks and matched them with the AACA recommendations, TA, and the curriculum of the anatomy course taught at Medical School in Split, Croatia. Methods TA, official recommendations of the AACA, 6 contemporary anatomy textbooks, and the structure of the anatomy course were analyzed for the proportion of the terms or text devoted to standard topographical regions of the body. The findings were correlated using Spearman ρ test. Results The curriculum outline correlated both with the AACA recommendations (Spearman ρ = 0.83, P = 0.015) and TA (Spearman ρ = 0.73, P = 0.046). Textbooks contained 8 distinct sections, 7 allocated to topographic anatomy regions and 1 to general anatomy concepts and principles. The structure of all textbooks correlated significantly with the course curriculum. However, 4 out of 6 textbooks did not correlate with TA and only a single textbook showed significant correlation with the AACA recommendations. Conclusion Anatomy textbooks vary in the amount of text dedicated to different parts of topographical anatomy and are not quite concordant with curriculum recommendations and standard anatomical terminology. Planning the structure of an anatomy course should not be based on a single book or recommendation but on evidence. PMID:19260144

  1. Thalamic Volume Is Reduced in Cervical and Laryngeal Dystonias (United States)

    Waugh, Jeff L.; Kuster, John K.; Levenstein, Jacob M.; Makris, Nikos; Multhaupt-Buell, Trisha J.; Sudarsky, Lewis R.; Breiter, Hans C.; Sharma, Nutan; Blood, Anne J.


    Background Dystonia, a debilitating movement disorder characterized by abnormal fixed positions and/or twisting postures, is associated with dysfunction of motor control networks. While gross brain lesions can produce secondary dystonias, advanced neuroimaging techniques have been required to identify network abnormalities in primary dystonias. Prior neuroimaging studies have provided valuable insights into the pathophysiology of dystonia, but few directly assessed the gross volume of motor control regions, and to our knowledge, none identified abnormalities common to multiple types of idiopathic focal dystonia. Methods We used two gross volumetric segmentation techniques and one voxelwise volumetric technique (voxel based morphometry, VBM) to compare regional volume between matched healthy controls and patients with idiopathic primary focal dystonia (cervical, n = 17, laryngeal, n = 7). We used (1) automated gross volume measures of eight motor control regions using the FreeSurfer analysis package; (2) blinded, anatomist-supervised manual segmentation of the whole thalamus (also gross volume); and (3) voxel based morphometry, which measures local T1-weighted signal intensity and estimates gray matter density or volume at the level of single voxels, for both whole-brain and thalamus. Results Using both automated and manual gross volumetry, we found a significant volume decrease only in the thalamus in two focal dystonias. Decreases in whole-thalamic volume were independent of head and brain size, laterality of symptoms, and duration. VBM measures did not differ between dystonia and control groups in any motor control region. Conclusions Reduced thalamic gross volume, detected in two independent analyses, suggests a common anatomical abnormality in cervical dystonia and spasmodic dysphonia. Defining the structural underpinnings of dystonia may require such complementary approaches. PMID:27171035

  3. The remarkable medical lineage of the Monro family: contributions of Alexander primus, secundus, and tertius. (United States)

    Wu, Osmond C; Manjila, Sunil; Malakooti, Nima; Cohen, Alan R


    Among the families that have influenced the development of modern medicine into what it is today, the Monro lineage stands as one of the most notable. Alexander Monro primus (1697-1767) was the first of 3 generations with the same name, a dynasty that spanned 126 years occupying the Chair of Anatomy one after the other at the University of Edinburgh. After becoming Professor of Anatomy at the University of Edinburgh in 1719, Monro primus played a principal role in the establishment of the University of Edinburgh School of Medicine and the Edinburgh Royal Infirmary. In 1726, he published The Anatomy of the Humane Bones, of which 8 editions were printed during his lifetime. His son, Alexander Monro secundus (1733-1817), arguably the most notable of the 3 men, succeeded him as Professor of Anatomy. A highly regarded lecturer and anatomist, Monro secundus studied under many great physicians, including William Hunter and Johann Friedrich Meckel the Elder, and was also teacher to other well-known figures at the time, such as Joseph Black and Thomas Trotter. His most notable contributions include his work with the lymphatic system, the interventricular foramen (of Monro), and the Monro-Kellie doctrine. Alexander Monro tertius (1773-1859), the last of the dynasty, also succeeded his father as Professor of Anatomy. His work included insights into abdominal aortic aneurysms and the anatomy of the genitourinary system. The prominent association of the Monro family with the University of Edinburgh and the effects of a tenured professorship under the concept of "Ad vitam aut culpam" over successive generations are also described. To the best of the authors' knowledge, this historical review of the Monro family is among the few published in neurosurgical literature. A vivid historical overview of the medical contributions of the most famous and influential dynasty of physicians in Edinburgh at that time is provided, with relevant excerpts from original publications.

  4. A metric analysis of Mumbai region (India) crania. (United States)

    Salve, Vishal M; Chandrashekhar, C H


    The human skull has been studied both metrically and non- metrically previously. These studies have thrown light on the functional and morphological aspect of the skull. Cranial index and other cranial indices are useful in differentiation of racial and gender difference. As studies on sexual dimorphism of cranium were very few we have taken this study to find out the differences in cranial index, vertical index and transverse vertical index of male and female crania at Mumbai region. This study was carried out on 210 (150 males and 60 females) dry human skulls available in department of anatomy of four Medical Colleges in Mumbai. The mean and SD of cranial index were 74.23 +/- 4.06; for males: 73.19 +/- 3.76, and for females: 76.84 +/- 3.63. The mean and SD of transverse vertical index were 100.84 +/- 6.31; for males: 102.19 +/- 6.15, and for females: 97.46 +/- 5.41. The difference between cranial index (p = 0.000000) and transverse vertical index (p = 0.000019) of male and female skulls were significant. The results of the present study show that majority of male skulls of Mumbai region belong to dolicocephalic group and majority of female skulls to mesocephalic.The result of present study shows that majority of male skulls of Mumbai region belong to acrocranial group (based on transverse vertical index). This data can be useful for forensic medicine experts, plastic surgeons, anatomist and oral surgeons for clinical and research purpose.

    Full Text Available Background: The palmaris longus is one of the most variable muscle in the human body, this variations are important not only for the anatomist but also radiologist, orthopaedic, plastic surgeons, clinicians, therapists. In view of this significance is performed this study with the purpose to determine the morphological variations of palmaris longus muscle. Methods and Findings: A total of 17 cadavers with different age groups were used for this study. The upper limbs region (34 sides were dissected carefully and photographed in the Morphology Laboratory at the University of Pamplona. Of the 34 limbs studied, 30 showed normal morphology of the Palmaris longus muscle (PL (88,2%; PL was absent in 3 subjects (8,85% of all examined forearm. Unilateral absence was found in 1 male subject (2,95% of all examined forearm; bilateral agenesis was found in 2 female subjects (5,9% of all examined forearm. Duplicated PL muscle was found in 1 male subject (2,95 % of all examined forearm. The palmaris longus muscle was innervated by branches of the median nerve .The accessory palmaris longus muscle was supplied by the deep branch of the ulnar nerve.  Palmaris longus muscle is a muscle located in the superficial layer of the anterior compartment of the forearm. It has a small belly arising from the medial epicondyle of the humerus, and its long thin tendon inserts into the palmar aponeurosis in the hand, the muscle has importance in medical clinic, surgery, radiological analysis, in studies about high-performance athletes, in genetics and anthropologic studies. Conclusions: The anatomical variations of the palmaris longus muscle must be documented of their clinical significance and their potential use in orthopaedic and reconstructive surgery.

  6. Exploring the use of a Facebook page in anatomy education. (United States)

    Jaffar, Akram Abood


    Facebook is the most popular social media site visited by university students on a daily basis. Consequently, Facebook is the logical place to start with for integrating social media technologies into education. This study explores how a faculty-administered Facebook Page can be used to supplement anatomy education beyond the traditional classroom. Observations were made on students' perceptions and effectiveness of using the Page, potential benefits and challenges of such use, and which Insights metrics best reflect user's engagement. The Human Anatomy Education Page was launched on Facebook and incorporated into anatomy resources for 157 medical students during two academic years. Students' use of Facebook and their perceptions of the Page were surveyed. Facebook's "Insights" tool was also used to evaluate Page performance during a period of 600 days. The majority of in-class students had a Facebook account which they adopted in education. Most students perceived Human Anatomy Education Page as effective in contributing to learning and favored "self-assessment" posts. The majority of students agreed that Facebook could be a suitable learning environment. The "Insights" tool revealed globally distributed fans with considerable Page interactions. The use of a faculty-administered Facebook Page provided a venue to enhance classroom teaching without intruding into students' social life. A wider educational use of Facebook should be adopted not only because students are embracing its use, but for its inherent potentials in boosting learning. The "Insights" metrics analyzed in this study might be helpful when establishing and evaluating the performance of education-oriented Facebook Pages. © 2013 American Association of Anatomists.

  7. Perception of medical students towards the clinical relevance of anatomy. (United States)

    Moxham, B J; Plaisant, O


    Recent developments worldwide in medical curricula have often led to major cuts in the teaching of human anatomy. Indeed, it is perceived by some that gross (topographical) anatomy has an exaggerated importance in the initial training of doctors. The value of anatomy consequently has frequently been considerably diminished within medical curricula that have reduced factual content. To date, however, there have been no objective studies into the perceived relevance of anatomy to clinical medicine that have aimed to quantify the attitudes of medical students. On the basis of responses to an attitude analysis questionnaire devised according to the precepts of Thurstone and Chave (The Measurement of Attitude: A Psychophysical Method and Some Experiments with a Scale for Measuring Attitude Toward the Church. Chicago, IL: University of Chicago Press, 1951), we investigated the perception of medical students at Cardiff and Paris towards the importance of gross anatomy to clinical medicine. This was undertaken during the early stages of their studies (when they were newly-admitted to university and were about to commence anatomy courses), immediately after finishing their anatomy courses, and later in the final year of medical studies. The results suggest that, even where there might be geopolitical and cultural backgrounds, students at all stages of their medical course share with professional anatomists the view that anatomy is a very important subject for their clinical studies. Thus, contrary to the unquantified beliefs of those who are sceptical about the purpose and value of anatomy in an undergraduate medical curriculum, the students themselves do not appear to share such beliefs.

  8. Learning style versus time spent studying and career choice: Which is associated with success in a combined undergraduate anatomy and physiology course? (United States)

    Farkas, Gary J; Mazurek, Ewa; Marone, Jane R


    The VARK learning style is a pedagogical focus in health care education. This study examines relationships of course performance vs. VARK learning preference, study time, and career plan among students enrolled in an undergraduate anatomy and physiology course at a large urban university. Students (n = 492) from the fall semester course completed a survey consisting of the VARK questionnaire, gender, academic year, career plans, and estimated hours spent per week in combined classroom and study time. Seventy-eight percent of students reported spending 15 or fewer hours per week studying. Study time and overall course score correlated significantly for the class as a whole (r = 0.111, P = 0.013), which was mainly due to lecture (r = 0.118, P = 0.009) performance. No significant differences were found among students grouped by learning styles. When corrected for academic year, overall course scores (mean ± SEM) for students planning to enter dentistry, medicine, optometry or pharmacy (79.89 ± 0.88%) were significantly higher than those of students planning to enter physical or occupational therapies (74.53 ± 1.15%; P = 0.033), as well as nurse/physician assistant programs (73.60 ± 1.3%; P = 0.040). Time spent studying was not significantly associated with either learning style or career choice. Our findings suggest that specific career goals and study time, not learning preferences, are associated with better performance among a diverse group of students in an undergraduate anatomy and physiology course. However, the extent to which prior academic preparation, cultural norms, and socioeconomic factors influenced these results requires further investigation. © 2015 American Association of Anatomists.

  9. 3D CBCT morphometric assessment of mental foramen in Arabic population and global comparison: imperative for invasive and non-invasive procedures in mandible. (United States)

    Alam, Mohammad Khursheed; Alhabib, Selham; Alzarea, Bader K; Irshad, Muhammad; Faruqi, Saif; Sghaireen, Mohd G; Patil, Santosh; Basri, Rehana


    Recent advancements in clinical dentistry have increased the possibilities of surgical procedures in the mental region. A detailed knowledge of mental foramen (MF) morphometry is significant to preserve integrity of the mental nerve trunk in surgical interventions such as orthognathic surgery, implant placement and anaesthetic block. The aim of this study was to determine the most accurate position of the mental foramen by using new assessment approach in a sample of dental patients presenting to the specialist dental clinic, College of Dentistry, Al Jouf University, Saudi Arabia. A retrospective study was performed using cone beam computed tomography (CBCT) of 600 patients (40.1 ± 11.78 years old). Following inclusion and exclusion criteria, 395 CBCT were finally obtained and analyzed for the most accurate position of the mental foramen (MF) by OnDemand 3D software (Seoul, Korea). Prevalence of shape of MF and accessory MF were also assessed. Pearson chi-square test was employed to test significant differences between genders and races. The most common horizontal and vertical position of the mental foramen was in line with the long axis of 2nd premolar (41.3%) and below the root apex level (93.2%), respectively. The most common shape of MF was round type (72.66%). The prevalence of accessory 2MF and 3MF was 2.28% and 0.25%, respectively. New information about MF presented in this article can help anatomists, prosthodontists, orthodontists, surgeons, forensic odontologists and paleoanthropologists to predict the position of the MF and perform safer surgeries.

  10. The development and assessment of an online microscopic anatomy laboratory course. (United States)

    Barbeau, Michele L; Johnson, Marjorie; Gibson, Candace; Rogers, Kem A


    Increasing enrollment in post-secondary institutions across North America, along with an increase in popularity of and demand for distance education is pressuring institutions to offer a greater number and variety of courses online. A fully online laboratory course in microscopic anatomy (histology) which can be taught simultaneously with a face-to-face (F2F) version of the same course has been developed. This full year course was offered in the Fall/Winter (FW) terms in both F2F and online formats. To ensure that the online course was of the same quality as the F2F format, a number of performance indicators were evaluated. The same course, offered exclusively online during the summer with a compressed time frame, was also evaluated. Senior undergraduate students self-selected which version of the course they would enroll in. Course assessment outcomes were compared while incoming grades were used as a predictor for course performance. There were no significant differences between the incoming grades for the F2F FW and Online FW courses; similarly, there were no significant differences between outcomes for these formats. There were significant differences between the incoming grades of the F2F FW and Summer Online students. However, there were no significant differences among any of the outcomes for any of the formats offered. Incoming grades were strong, significant predictors of course performance for both formats. These results indicate that an online laboratory course in microscopic anatomy is an effective format for delivering histology course content, therefore giving students greater options for course selections. © 2013 American Association of Anatomists.

  11. Dinosaurs in the year of Darwin. (United States)

    Dodson, Peter


    This special issue of The Anatomical Record explores the recent advances in the functional morphology and paleobiology of dinosaurs. Although Darwin did not study dinosaurs because paleontology was in its infancy a century and half ago, he considered both paleontology and anatomy as essential subjects for establishing the validity of evolution. The study of dinosaurs constitutes a vigorous subdiscipline within vertebrate paleontology, and anatomists and evolutionary functional morphologists constitute an especially creative subgroup within dinosaur paleontology. The collection of 17 papers presented in this issue encompass cranial anatomy, postcranial anatomy, and paleobiology of dinosaurs and other archosaurs. Soft tissue subjects include studies of brain structure, jaw adductor muscles, and keratinous appendages of the skull. Taxonomically, it includes four papers with a focus on theropods, including Tyrannosaurus, five papers dealing with ceratopsians, three papers on hadrosaurs, and one on ankylosaurs. Modern anatomical techniques such as CT scanning, finite element analysis, and high resolution histology are emphasized. The visual presentation of results of these studies is spectacular. Results include the first-ever life history table of a plant-eating dinosaur; a determination of the head orientation of Tyrannosaurus and its relatives based on interpretation of the semicircular canals. The claws of Velociraptor appear to best adapted for tree climbing, but not for horrific predatory activities. Pachyrhinosaurus evidently used its massive head for head butting. The tail club of the armored dinosaur Euoplocephalus had the structural integrity to be used as a weapon. The pages abound with insights such as these.

  12. One «Both» Sex«es»: Observations, suppositions, and airy speculations on fetal sex anatomy in British scientific literature, 1794-1871. (United States)

    Brooks, Ross


    The hegemony of the two-sex paradigm in the European scientific imagination and wider culture did not automatically equate to the hegemony of two discrete genders. In fact, two sexes facilitated a variety of gender choices: two singular and a number of double or otherwise intersexed (most commonly referred to as "hermaphrodite" or "bisexual" in its anatomical sense). This article explores some key British medical and allied scientific texts, with reference to associated Continental literature, as a means of illustrating the complexity of the two-sex paradigm and the unexpected transformation of gender possibilities that it helped produce through the early and middle decades of the nineteenth century. Discourses surrounding the first direct observations of the earliest development of fetal urinogenital anatomy were pivotal. The prevailing view that the incipient embryo was sexually undifferentiated (a paragon of the one-sex paradigm) was challenged by the Edinburgh anatomist Robert Knox, initially as he sought to bolster his professional reputation at the height of the Burke and Hare "body-snatching" scandal. Knox suggested that every embryo began life in an essentially dual-sexed state, an individual's sex anatomy depending on the greater or lesser development of component female and male structures. Greater clarification on the contested status of the homology-hermaphrodite distinction was achieved with the discovery of the early co-existence of the excretory duct of the Wolffian body (mesonephric duct) and the Müllerian duct (paramesonephric duct), an observation that made anatomical bisexuality difficult to ignore. The nineteenth-century's greatest champion of primordial hermaphroditism was Charles Darwin who was pivotal in phylogenizing the principle and establishing the premise that (in his own words) "Every man & woman is hermaphrodite," a foundation stone of late-nineteenth-century sexology. © The Author 2013.

  13. "Celebration of the smile". (United States)

    Crawford, P R


    April is Dental Health Month--a month especially set aside to alert Canadians that Dental Health is indeed a major ingredient of the total quality of life. This year, the campaign's primary focus will not be mastication, function, freedom from disease or pain, but "Celebration of the Smile." A Smile is infectious, it's contagious, and one of the world's greatest bargains. The returns are immeasurable. When truly genuine and freely given, the Smile elicits almost instant trust and friendship. No frown can ever do that! And it takes so very little effort and energy. We are not sure what anatomist conducted the research but it is reported that three times more muscles are required to frown than to Smile! Dentists everywhere can take much pride in their contribution to enhancing one of Nature's most precious commodities--the Smile. What a long road it has been from the primitive attempts of just a hundred years ago when alleviating pain was the priority and any crude attempt to enhance appearance was secondary. Only 25 years ago silicate cement was often the only material available for anterior teeth. Far, far too many beautiful Smiles were marred with dark halos around poor fillings and recurrent decay. Missing teeth were commonplace; there were gaps, spaces and "flipper dentures." It's hard to believe how rapidly we have advanced in so short a time. Taken for granted today are caries-free mouths, composite filling materials that defy detection, bonded porcelain veneers and fixed prostheses that can even improve where Nature has "faltered."(ABSTRACT TRUNCATED AT 250 WORDS)

  14. Terminologia anatomica in the past and the future from perspective of 110th anniversary of Polish Anatomical Terminology. (United States)

    Gielecki, J; Zurada, A; Osman, N


    Professional terminology is commonplace, particularly in the fields of mathematics, medicine, veterinary and natural sciences. The use of the terminology can be international, as it is with Anatomical Terminology (AT). In the early age of modern education, anatomists adopted Latin as the international language for AT. However, at the end of the 20th century, the English language became more predominant around the world. It can be said that the AT is a specific collection of scientific terms. One of the major flaws in early AT was that body structures were described by varying names, while some of the terms was irrational in nature, and confusing. At this time, different international committees were working on preparing a unified final version of the AT, which in the end consisted of 5,640 terms (4,286 originally from the Basle Nomina Anatomica, BNA). Also, each country wanted to have its own nomenclature. In order to accomplish this, each country based their nomenclature on the international AT, and then translated it into their own language. The history of the Polish Anatomical Terminology (PAT) is unique, and follows the events of history. It was first published in 1898, at a time when its neighbours partitioned the territory of Poland. During 150 years, the Polish culture and language was under the Russification and Germanization policy. It is important to note, that even with such difficult circumstances, the PAT was the first national AT in the world. The PAT was a union of the accepted first BNA in Latin and the original Polish anatomical equivalents. This union formed the basis for theoretical and clinical medicine in Poland.

  15. Terminology of the prostate and related structures. (United States)

    Wendell-Smith, C


    The various studies of J.E. McNeal (1968ndash;1977) established with precision the different sites of predilection for prostatic carcinomas, benign prostatic hypertrophy (BPH), and inflammation, making the division of the prostate into right, left, and middle lobes and isthmus inadequate for their description. Unfortunately, his positional terms for the sites (peripheral, central, transition, and preprostatic) are not based on the usual parameters and cannot be directly related to those of other workers. Nevertheless, the International Federation of Associations of Anatomists' Federative Committee on Anatomical Terminology has made recommendations in Terminologia Anatomica, based on his findings but modified to take some account of those of Tisell and Salander (1975 Scand J Urol Nephrol 1975 9:185-191). The use of the term lobe is confined to the right and left lobes and the variable middle lobe. The term lobule is used for the subdivisions, which are named from the anatomical position. Thus each side has a superomedial, an anteromedial, an inferoposterior, and an inferolateral lobule. Also necessary to describe a site of predilection is a peri-urethral gland zone. In ultrasound diagnosis, the trapezoid area is important: its upper limit is the rectoperinealis, its anterior limit is the intermediate part of the urethra, its lower limit is the anoperinealis, and its posterior limit is the anorectal junction. Confusion at the bladder neck is resolved by recognizing that the position of the internal urethral orifice varies with functional state of the bladder: while it is filling the orifice lies above the base of the prostate; when voiding begins, the orifice descends to the base of the prostate; between the filling internal orifice and the emptying internal orifice is the bladder neck part of the urethra.

  16. Novel femoral artery terminology: integrating anatomy and clinical procedures leading to standardized intuitive nomenclature. (United States)

    Benninger, Brion


    The objective of this study is to investigate the terminology of the femoral artery and recommended alternative terminology that satisfies both anatomy and clinical arenas.The femoral artery (FA) is often defined as the continuation of the external iliac artery. Specifically, when the external iliac artery reaches directly beneath the inguinal ligament, it becomes the FA. Currently, Terminologia Anatomica (TA) records the profunda femoris or deep femoral as a terminal branch. Clinicians often use superficial femoral artery (SFA) rather than FA and profunda or deep FA. SFA is actually very deep and well protected for most of its journey. On observation, the terminology in current use is not intuitive. The objective of this study was to investigate the terminology associated with the anatomical and clinical anatomical interpretations of the FA and its terminal branches and to suggest a more appropriate terminology that addresses the points of view of the macro anatomist, as well as that of the clinician. Literature search was conducted regarding the nomenclature of the FA and its terminal branches. Dissection of 89 embalmed cadavers (49F, 40M, ages 47-89) was conducted to analyze the morphology of the FA and its branches. Perusal of the literature revealed a difference in terminology between anatomical and clinical textbooks/atlases/journals regarding the FA and its terminal branch. Our dissections suggested that the FA may be better defined vis-à-vis its relationship to the anterior and posterior compartments of the thigh. A difference in terminology exists between the anatomical and clinical arenas. A need for a standardized terminology is necessary because clinicians and their publishers have not adopted TA. This study suggests that the current FA be considered the common FA and the continuation of the FA, the SFA be renamed the anterior FA and the current profunda (the deep FA) be renamed the posterior FA, respectively. The proposed terminology mirrors the lower

  17. Understanding brain, mind and soul: contributions from neurology and neurosurgery. (United States)

    Pandya, Sunil K


    Treatment of diseases of the brain by drugs or surgery necessitates an understanding of its structure and functions. The philosophical neurosurgeon soon encounters difficulties when localising the abstract concepts of mind and soul within the tangible 1300-gram organ containing 100 billion neurones. Hippocrates had focused attention on the brain as the seat of the mind. The tabula rasa postulated by Aristotle cannot be localised to a particular part of the brain with the confidence that we can localise spoken speech to Broca's area or the movement of limbs to the contralateral motor cortex. Galen's localisation of imagination, reasoning, judgement and memory in the cerebral ventricles collapsed once it was evident that the functional units-neurones-lay in the parenchyma of the brain. Experiences gained from accidental injuries (Phineas Gage) or temporal lobe resection (William Beecher Scoville); studies on how we see and hear and more recent data from functional magnetic resonance studies have made us aware of the extensive network of neurones in the cerebral hemispheres that subserve the functions of the mind. The soul or atman, credited with the ability to enliven the body, was located by ancient anatomists and philosophers in the lungs or heart, in the pineal gland (Descartes), and generally in the brain. When the deeper parts of the brain came within the reach of neurosurgeons, the brainstem proved exceptionally delicate and vulnerable. The concept of brain death after irreversible damage to it has made all of us aware of 'the cocktail of brain soup and spark' in the brainstem so necessary for life. If there be a soul in each of us, surely, it is enshrined here.

  18. The ATLAS project: The effects of a constructionist digital laboratory project on undergraduate laboratory performance. (United States)

    Shoepe, Todd C; Cavedon, Dana K; Derian, Joseph M; Levy, Celine S; Morales, Amy


    Anatomical education is a dynamic field where developments in the implementation of constructive, situated-learning show promise in improving student achievement. The purpose of this study was to examine the effectiveness of an individualized, technology heavy project in promoting student performance in a combined anatomy and physiology laboratory course. Mixed-methods research was used to compare two cohorts of anatomy laboratories separated by the adoption of a new laboratory atlas project, which were defined as preceding (PRE) and following the adoption of the Anatomical Teaching and Learning Assessment Study (ATLAS; POST). The ATLAS project required the creation of a student-generated, photographic atlas via acquisition of specimen images taken with tablet technology and digital microscope cameras throughout the semester. Images were transferred to laptops, digitally labeled and photo edited weekly, and compiled into a digital book using Internet publishing freeware for final project submission. An analysis of covariance confirmed that student final examination scores were improved (P project (PRE, n = 75; POST, n = 90; means ± SE; 74.9 ± 0.9 versus 78.1 ± 0.8, respectively) after controlling for cumulative student grade point average. Analysis of questionnaires collected (n = 68) from the post group suggested students identified with atlas objectives, appreciated the comprehensive value in final examination preparation, and the constructionism involved, but recommended alterations in assignment logistics and the format of the final version. Constructionist, comprehensive term-projects utilizing student-preferred technologies could be used to improve performance toward student learning outcomes. © 2014 American Association of Anatomists.

  19. Head to head: The role of academic competition in undergraduate anatomical education. (United States)

    Van Nuland, Sonya E; Roach, Victoria A; Wilson, Timothy D; Belliveau, Daniel J


    Competition is a key element in many educational games and is often adopted by educators in an effort to motivate and excite their students. Yet, the use of academic competition in educational institutions remains the subject of much debate. Opponents argue that academic competition causes an increase in student anxiety and divides their attention. However, if the contexts of academic competition are defined, could the inclusion of a game-like competition in a university course be a viable and beneficial method of engaging students? Students (n = 67) were recruited from an undergraduate human anatomy course at Western University. Using a crossover design, students were exposed to a competitive tournament either at the time of their first term test or second term test. The anatomical knowledge of participating students was assessed prior to the start of the study using a baseline anatomy test. Following treatment with an online competitive anatomy tournament, student's term test grades and final course grades were analyzed. Both the second term test scores (F(2,64) = 3.743, P = 0.029) and overall course grades (F(2,64) = 3.356, P = 0.041) were found to be significantly different (P < 0.05) for individuals in the competitive group when compared to their non-competing peers. As suggested by the literature where organized competition in the classroom correlates to improved academic performance, this study uncovered significant results pertaining to increased academic performance resulting from participating in tournament-based competition. In light of these positive results, further exploration of the effects of academic competition on student performance across age brackets and disciplines is warranted. © 2014 American Association of Anatomists.

  20. Morphometric analysis of the mandible in the Durban Metropolitan population of South Africa. (United States)

    Ishwarkumar, S; Pillay, P; Haffajee, M R; Satyapal, K S


    The identification of an individual from skeletal remains plays a vital role in forensic investigation as it is essential for the identification of the individual's age, sex, and/or race and further analysis. Skeletal characteristics differ from one population group to another since population-specific osteometric standards exist for sex determination. Since the mandible is the largest, strongest and most durable compact facial bone, it is the best preserved after death. While sexual dimorphism of the mandible is indicated by its shape and size, morphometric analysis is more accurate in the determination of sex from the skull. The aim of this study was to evaluate the morphometric parameters of the mandible in the Durban Metropolitan population. Various morphometric parameters of the mandible were measured and assessed in 265 digital panoramic radiographs aged between 16 and 30 years (n = 530). Each parameter recorded was statistically analysed using SPSS to determine if a relationship existed between the parameter, and sex and age. In this study the morphometric parameters of the male mandibles were greater than that of the females. This concurred with the findings of previous studies. The length of the mandibular ramus on the right and left sides was statistically significant with sex. This correlated with previous studies, indicating that the length of the mandibular ramus generally has higher sexual dimorphism than any other morphometric mandibular parameter (p = 0.000). However, only the length of the right mandibular body was statistically significant when compared with sex (p = 0.040). The findings of this study may assist forensic investigators, anatomists, anthropologists and maxillo-facial surgeons.

  1. Links between Evolution, Development, Human Anatomy, Pathology, and Medicine, with A Proposition of A Re-defined Anatomical Position and Notes on Constraints and Morphological "Imperfections". (United States)

    Diogo, Rui; Molnar, Julia


    Surprisingly the oldest formal discipline in medicine (anatomy) has not yet felt the full impact of evolutionary developmental biology. In medical anatomy courses and textbooks, the human body is still too often described as though it is a "perfect machine." In fact, the study of human anatomy predates evolutionary theory; therefore, many of its conventions continue to be outdated, making it difficult to study, understand, and treat the human body, and to compare it with that of other, nonbipedal animals, including other primates. Moreover, such an erroneous view of our anatomy as "perfect" can be used to fuel nonevolutionary ideologies such as intelligent design. In the section An Evolutionary and Developmental Approach to Human Anatomical Position of this paper, we propose the redefinition of the "human standard anatomical position" used in textbooks to be consistent with human evolutionary and developmental history. This redefined position also simplifies, for students and practitioners of the health professions, the study and learning of embryonic muscle groups (each group including muscles derived from the same/ontogenetically closely related primordium/primordia) and joint movements and highlights the topological correspondence between the upper and lower limbs. Section Evolutionary and Developmental Constraints, "Imperfections" and Sports Pathologies continues the theme by describing examples of apparently "illogical" characteristics of the human body that only make sense when one understands the developmental and evolutionary constraints that have accumulated over millions of years. We focus, in particular, on musculoskeletal functional problems and sports pathologies to emphasize the links with pathology and medicine. These examples demonstrate how incorporating evolutionary theory into anatomy education can be helpful for medical students, teachers, researchers, and physicians, as well as for anatomists, functional morphologists, and evolutionary and

  2. Evaluating dissection in the gross anatomy course: Correlation between quality of laboratory dissection and students outcomes. (United States)

    Nwachukwu, Chika; Lachman, Nirusha; Pawlina, Wojciech


    Anatomy learned by active exploration through dissection has many proven benefits including improvement of anatomic knowledge. Decreased laboratory time may affect the quality of dissection and ultimately lower student performance in anatomy translating to lower knowledge acquisition. The aim of this study was to determine whether the quality of students' dissection in teams correlates with their performance in the gross anatomy course. Quality of dissections for each team enrolled in a gross anatomy course at Mayo Medical School was evaluated biweekly using a five-point rubric based on course learning objectives. Assessment of anatomic knowledge was based on sequential laboratory practice practical examination scores, achievements on daily audience response system (ARS) quizzes, and final practical, written, and National Board of Medical Examiners(®) (NBME(®) ) Gross Anatomy and Embryology Subject Examinations. Twelve teams comprising 48 students were included in the study. There was a positive correlation between dissection quality and practice practical examination score (R = 0.83) and a negative correlation between dissection quality and ARS quizzes (R = -0.985). Dissection teams with a passing score on their dissection evaluations (>70%) performed better on their final examinations. Based on an end of course survey, students agreed that dissection evaluations should continue to be a part of the course. This study showed that better quality of dissection was associated with higher scores on practice practical examinations, final practical, written, and NBME examinations. The study demonstrated a positive correlation between dissection evaluations, accompanied by formative feedback during the course, and higher scores on final course assessments. © 2014 American Association of Anatomists.

  3. Felix Vicq d'Azyr: anatomy, medicine and revolution. (United States)

    Parent, André


    Félix Vicq d'Azyr was born in 1748 in the small town of Valognes, Normandy. He studied medicine in Paris but he was particularly impressed by the lectures given at the Jardin du Roi by the comparative anatomist Louis Daubenton and the surgeon Antoine Petit. In 1773, Vicq d'Azyr initiated a series of successful lectures on human and animal anatomy at the Paris Medical School, from which he received his medical degree in 1774. He was elected the same year at the Academy of Sciences at age 26, thanks to his outstanding contributions to comparative anatomy. Vicq d'Azyr became widely known after his successful management of a severe cattle plague that occurred in the southern part of France in 1774, an event that led to the foundation of the Royal Society of Medicine in 1778. As Permanent Secretary of this society, Vicq d'Azyr wrote several eulogies that were models of eloquence and erudition and worth him a seat at the French Academy in 1788. Vicq d'Azyr published in 1786 a remarkable anatomy and physiology treatise: a large in-folio that contained original descriptions illustrated by means of nature-sized, colored, human brain figures of a quality and exactitude never attained before. In 1789, Vicq d'Azyr was appointed physician to the Queen Marie-Antoinette and, in 1790, he presented to the Constituent Assembly a decisive plan to reform the teaching of medicine in France. Unfortunately, Vicq d'Azyr did not survive the turmoil of the French Revolution; he died at age 46 on June 20, 1794.

  4. In dogs we trust? Intersubjectivity, response-able relations, and the making of mine detector dogs. (United States)

    Kirk, Robert G W


    The utility of the dog as a mine detector has divided the mine clearance community since dogs were first used for this purpose during the Second World War. This paper adopts a historical perspective to investigate how, why, and to what consequence, the use of minedogs remains contested despite decades of research into their abilities. It explores the changing factors that have made it possible to think that dogs could, or could not, serve as reliable detectors of landmines over time. Beginning with an analysis of the wartime context that shaped the creation of minedogs, the paper then examines two contemporaneous investigations undertaken in the 1950s. The first, a British investigation pursued by the anatomist Solly Zuckerman, concluded that dogs could never be the mine hunter's best friend. The second, an American study led by the parapsychologist J. B. Rhine, suggested dogs were potentially useful for mine clearance. Drawing on literature from science studies and the emerging subdiscipline of "animal studies," it is argued that cross-species intersubjectivity played a significant role in determining these different positions. The conceptual landscapes of Zuckerman and Rhine's disciplinary backgrounds are shown to have produced distinct approaches to managing cross-species relations, thus explaining how diverse opinions on minedog can coexist. In conclusion, it is shown that the way one structures relationships between humans and animals has profound impact on the knowledge and labor subsequently produced, a process that cannot be separated from ethical consequence. © 2013 The Authors.

  5. E-learning, dual-task, and cognitive load: The anatomy of a failed experiment. (United States)

    Van Nuland, Sonya E; Rogers, Kem A


    The rising popularity of commercial anatomy e-learning tools has been sustained, in part, due to increased annual enrollment and a reduction in laboratory hours across educational institutions. While e-learning tools continue to gain popularity, the research methodologies used to investigate their impact on learning remain imprecise. As new user interfaces are introduced, it is critical to understand how functionality can influence the load placed on a student's memory resources, also known as cognitive load. To study cognitive load, a dual-task paradigm wherein a learner performs two tasks simultaneously is often used, however, its application within educational research remains uncommon. Using previous paradigms as a guide, a dual-task methodology was developed to assess the cognitive load imposed by two commercial anatomical e-learning tools. Results indicate that the standard dual-task paradigm, as described in the literature, is insensitive to the cognitive load disparities across e-learning tool interfaces. Confounding variables included automation of responses, task performance tradeoff, and poor understanding of primary task cognitive load requirements, leading to unreliable quantitative results. By modifying the secondary task from a basic visual response to a more cognitively demanding task, such as a modified Stroop test, the automation of secondary task responses can be reduced. Furthermore, by recording baseline measures for the primary task as well as the secondary task, it is possible for task performance tradeoff to be detected. Lastly, it is imperative that the cognitive load of the primary task be designed such that it does not overwhelm the individual's ability to learn new material. © 2015 American Association of Anatomists.

  6. Goethe's phenomenology of nature: a juvenilization of science. (United States)

    Skaftnesmo, Trond


    Empirical science is not a mere collection of facts. It builds theories and frames hypotheses within those theories. Empirical theories are stated as plausible answers to questions we pose to nature. According to the Galilean-Baconian tradition within science, these questions should basically explore the causes of observed phenomena, and further be restricted to the measurable and quantitative realm. Thus, the answers are generally expected to explain the effective causes behind the actual phenomena. By framing falsifiable hypotheses, the theories are tested against the empirical foundation on which they rest. In this way we try to relieve science from false theories. Thus, we have two epistemological levels: First, the theoretical level; the scientific theory explaining the phenomena, and second, the empirical level; the phenomena or facts verifying or falsifying those theories. According to the poet and multi-scientist Johann Wolfgang von Goethe (1749-1832), there is however another way of science, namely an approach where these two levels fuse and become one. Goethe intended this approach to be a complementation of the Galilean-Baconian method, more than an alternative. He considered his "hypothesis-free method" to be a more comprehensive and secure way to understand nature. Whereas the Galilean-Baconian method aimed at explaining the effective causes of natural phenomena, in order to control and exploit nature for technical and industrial purposes, Goethe aimed at an exposition of the inherent meaning of the phenomena.We will explore, exemplify and discuss this approach with reference to the inherently Goethean phenomenology of evolution credited to the Dutch anatomist Louis Bolk (1866-1930), later commented and complemented by Stephen Jay Gould (1941-2002) and Jos Verhulst (1949 ). In the course of this presentation we will outline the Goethean approach as a method representing a juvenilization or in Bolk's terms, a fetalization of science.

  7. Muscle Logic: New Knowledge Resource for Anatomy Enables Comprehensive Searches of the Literature on the Feeding Muscles of Mammals. (United States)

    Druzinsky, Robert E; Balhoff, James P; Crompton, Alfred W; Done, James; German, Rebecca Z; Haendel, Melissa A; Herrel, Anthony; Herring, Susan W; Lapp, Hilmar; Mabee, Paula M; Muller, Hans-Michael; Mungall, Christopher J; Sternberg, Paul W; Van Auken, Kimberly; Vinyard, Christopher J; Williams, Susan H; Wall, Christine E


    In recent years large bibliographic databases have made much of the published literature of biology available for searches. However, the capabilities of the search engines integrated into these databases for text-based bibliographic searches are limited. To enable searches that deliver the results expected by comparative anatomists, an underlying logical structure known as an ontology is required. Here we present the Mammalian Feeding Muscle Ontology (MFMO), a multi-species ontology focused on anatomical structures that participate in feeding and other oral/pharyngeal behaviors. A unique feature of the MFMO is that a simple, computable, definition of each muscle, which includes its attachments and innervation, is true across mammals. This construction mirrors the logical foundation of comparative anatomy and permits searches using language familiar to biologists. Further, it provides a template for muscles that will be useful in extending any anatomy ontology. The MFMO is developed to support the Feeding Experiments End-User Database Project (FEED,, a publicly-available, online repository for physiological data collected from in vivo studies of feeding (e.g., mastication, biting, swallowing) in mammals. Currently the MFMO is integrated into FEED and also into two literature-specific implementations of Textpresso, a text-mining system that facilitates powerful searches of a corpus of scientific publications. We evaluate the MFMO by asking questions that test the ability of the ontology to return appropriate answers (competency questions). We compare the results of queries of the MFMO to results from similar searches in PubMed and Google Scholar. Our tests demonstrate that the MFMO is competent to answer queries formed in the common language of comparative anatomy, but PubMed and Google Scholar are not. Overall, our results show that by incorporating anatomical ontologies into searches, an expanded and anatomically comprehensive set of results

  8. Evaluation of a lecture recording system in a medical curriculum. (United States)

    Bacro, Thierry R H; Gebregziabher, Mulugeta; Fitzharris, Timothy P


    Recently, the Medical University of South Carolina adopted a lecture recording system (LRS). A retrospective study of LRS was implemented to document the students' perceptions, pattern of usage, and impact on the students' grades in three basic sciences courses (Cell Biology/Histology, Physiology, and Neurosciences). The number of accesses and length of viewings of the recordings were recorded per week for each student and correlated with the grades in each of the three courses. Attendance records were not available. The results showed considerable variability in the use of the LRS by both faculty and students during the entire semester and across all three courses, including week to week variations. Data indicated that 30% of the students did not use the LRS at all with 41% of the students using it very little (less than 10 times for a total of 131 recordings). Specific patterns of usage were identified for each of the three courses throughout the semester, with an increase in access prior or during examination weeks. However, the statistical analysis showed that there was no correlation between the final grades and the usage of LRS. Finally, a survey of the students' perception showed that 74% agreed/strongly agreed that the recordings were useful with 6% disagreeing/strongly disagreeing and 11% undecided. This study showed that the use of LRS might be a viable alternative for students unable to attend lecture due to circumstances such as illness but that more research is needed to truly understand the best pedagogical use of LRS.

  9. Comparison of a gross anatomy laboratory to online anatomy software for teaching anatomy. (United States)

    Mathiowetz, Virgil; Yu, Chih-Huang; Quake-Rapp, Cindee


    This study was designed to assess the grades, self-perceived learning, and satisfaction between occupational therapy students who used a gross anatomy laboratory versus online anatomy software (AnatomyTV) as tools to learn anatomy at a large public university and a satellite campus in the mid-western United States. The goal was to determine if equivalent learning outcomes could be achieved regardless of learning tool used. In addition, it was important to determine why students chose the gross anatomy laboratory over online AnatomyTV. A two group, post-test only design was used with data gathered at the end of the course. Primary outcomes were students' grades, self-perceived learning, and satisfaction. In addition, a survey was used to collect descriptive data. One cadaver prosection was available for every four students in the gross anatomy laboratory. AnatomyTV was available online through the university library. At the conclusion of the course, the gross anatomy laboratory group had significantly higher grade percentage, self-perceived learning, and satisfaction than the AnatomyTV group. However, the practical significance of the difference is debatable. The significantly greater time spent in gross anatomy laboratory during the laboratory portion of the course may have affected the study outcomes. In addition, some students may find the difference in (B+) versus (A-) grade as not practically significant. Further research needs to be conducted to identify what specific anatomy teaching resources are most effective beyond prosection for students without access to a gross anatomy laboratory. © 2015 American Association of Anatomists.

  10. It's all in the mime: Actions speak louder than words when teaching the cranial nerves (United States)

    Stephens, Bruce Warren


    Cranial nerve (CN) knowledge is essential for students in health professions. Gestures and body movements (e.g., mime) have been shown to improve cognition and satisfaction with anatomy teaching. The aim of this pilot study was to compare the effectiveness of didactic lecturing with that of miming lecturing for student learning of the CNs. The research design involved exposure of the same group of students to didactic followed by miming lecturing of CNs. The effectiveness of each lecturing strategy was measured via pre‐ and post‐testing. Student perceptions of these strategies were measured by a survey. As an example of miming, gestures for CN VII included funny faces for muscles of facial expression, kangaroo vocalization for taste, spitting action for saliva production, and crying for lacrimal gland production. Accounting for extra duration of the miming lecture, it was shown that pre‐ to post‐test improvement was higher for the miming presentation than for the didactic (0.47 ± 0.03 marks/minute versus 0.33 ± 0.03, n = 39, P Students perceived that the miming lecture was more interactive, engaging, effective, and motivating to attend (mean on five‐point Likert scale: 4.62, 4.64, 4.56, 4.31, respectively) than the didactic lecture. In the final examination, performance was better (P students scoring ≤60%. While mediating factors need elucidation (e.g., learning due to repetition of content), this study's findings support the theory that gestures and body movements help learners to acquire anatomical knowledge.

  11. Students helping students: Evaluating a pilot program of peer teaching for an undergraduate course in human anatomy (United States)

    Love Green, Jennifer K.; Illerbrun, Sara L.; Holness, Duncan A.; Illerbrun, Samantha J.; Haus, Kara A.; Poirier, Sylvianne M.; Sveinson, Katherine L.


    The educational literature generally suggests that supplemental instruction (SI) is effective in improving academic performance in traditionally difficult courses. A pilot program of peer teaching based on the SI model was implemented for an undergraduate course in human anatomy. Students in the course were stratified into three groups based on the number of peer teaching sessions they attended: nonattendees (0 sessions), infrequently attended (1‐3 sessions), and frequently attended (≥ 4 sessions). After controlling for academic preparedness [i.e., admission grade point average (AGPA)] using an analysis of covariance, the final grades of frequent attendees were significantly higher than those of nonattendees (P = 0.025) and infrequent attendees (P = 0.015). A multiple regression analysis was performed to estimate the relative independent contribution of several variables in predicting the final grade. The results suggest that frequent attendance (β = 0.245, P = 0.007) and AGPA (β = 0.555, P student (β = −0.217, P = 0.006) was a significant negative predictor. Collectively, these results suggest that attending a certain number of sessions may be required to gain a noticeable benefit from the program, and that first‐year students (particularly those with a lower level of academic preparedness) would likely stand to benefit from maximally using the program. End‐of‐semester surveys and reports indicate that the program had several additional benefits, both to the students taking the course and to the students who served as program leaders.

  12. Independent learning modules enhance student performance and understanding of anatomy. (United States)

    Serrat, Maria A; Dom, Aaron M; Buchanan, James T; Williams, Alison R; Efaw, Morgan L; Richardson, Laura L


    Didactic lessons are only one part of the multimodal teaching strategies used in gross anatomy courses today. Increased emphasis is placed on providing more opportunities for students to develop lifelong learning and critical thinking skills during medical training. In a pilot program designed to promote more engaged and independent learning in anatomy, self-study modules were introduced to supplement human gross anatomy instruction at Joan C. Edwards School of Medicine at Marshall University. Modules use three-dimensional constructs to help students understand complex anatomical regions. Resources are self-contained in portable bins and are accessible at any time. Students use modules individually or in groups in a structured self-study format that augments material presented in lecture and laboratory. Pilot outcome data, measured by feedback surveys and examination performance statistics, suggest that the activity may be improving learning in gross anatomy. Positive feedback on both pre- and post-examination surveys showed that students felt the activity helped to increase their understanding of the topic. In concordance with student perception, average examination scores on module-related laboratory and lecture questions were higher in the two years of the pilot program compared with the year before its initiation. Modules can be fabricated on a modest budget using minimal resources, making implementation practical for smaller institutions. Upper level medical students assist in module design and upkeep, enabling continuous opportunities for vertical integration across the curriculum. This resource offers a feasible mechanism for enhancing independent and lifelong learning competencies, which could be a valuable complement to any gross anatomy curriculum. © 2014 American Association of Anatomists.

  13. A history of normal plates, tables and stages in vertebrate embryology. (United States)

    Hopwood, Nick


    Developmental biology is today unimaginable without the normal stages that define standard divisions of development. This history of normal stages, and the related normal plates and normal tables, shows how these standards have shaped and been shaped by disciplinary change in vertebrate embryology. The article highlights the Normal Plates of the Development of the Vertebrates edited by the German anatomist Franz Keibel (16 volumes, 1897-1938). These were a major response to problems in the relations between ontogeny and phylogeny that amounted in practical terms to a crisis in staging embryos, not just between, but (for some) also within species. Keibel's design adapted a plate by Wilhelm His and tables by Albert Oppel in order to go beyond the already controversial comparative plates of the Darwinist propagandist Ernst Haeckel. The project responded to local pressures, including intense concern with individual variation, but recruited internationally and mapped an embryological empire. Though theoretically inconclusive, the plates became standard laboratory tools and forged a network within which the Institut International d'Embryologie (today the International Society of Developmental Biologists) was founded in 1911. After World War I, experimentalists, led by Ross Harrison and Viktor Hamburger, and human embryologists, especially George Streeter at the Carnegie Department of Embryology, transformed Keibel's complex, bulky tomes to suit their own contrasting demands. In developmental biology after World War II, normal stages-reduced to a few journal pages-helped domesticate model organisms. Staging systems had emerged from discussions that questioned the very possibility of assigning an embryo to a stage. The historical issues resonate today as developmental biologists work to improve and extend stage series, to make results from different laboratories easier to compare and to take individual variation into account.

  14. Subclinical abnormal gyration pattern, a potential anatomic marker of epileptogenic zone in patients with magnetic resonance imaging negative frontal lobe epilepsy

    International Nuclear Information System (INIS)

    Regis, J.; Tamura, M.; Park, M.C.; McGonigal, A.; Riviere, D.; Coulon, O.; Bartolomei, F.; Girard, N.; Figarella-Branger, D.; Chauvel, P.; Mangin, J.F.


    Background: Epilepsy surgery for magnetic resonance imaging (MRI)-negative patients has a less favorable outcome. Objective: Detection of subclinical abnormal gyration (SAG) patterns and their potential contribution to assessment of the topography of the epileptogenic zone (EZ) is addressed in MRI-negative patients with frontal lobe epilepsy. Methods: Between September 1998 and July 2005, 12 MRI-negative frontal lobe epilepsy patients underwent stereo-electro-encephalography with postcorticectomy follow-up of longer than 1 year (average, 3.3 years). Original software (BrainVISA/Anatomist, trained on a database of normal volunteers was used to determine which sulci had morphology out of the normal range (SAG). Topography of the EZ, SAG pattern, corticectomy, postoperative seizure control, and histopathology were analyzed. Results: At last follow-up, 8 of 12 patients (66.7%) were Engel class I (7 IA and 1 IB), 2 class II, and 2 class IV. Small focal cortical dysplasia was histologically diagnosed in 9 of the 12 patients (75%), including 7 of 8 seizure-free patients (87.5%). A SAG pattern was found to be in the EZ area in 9 patients (75%), in the ipsilateral frontal lobe out of the EZ in 2, and limited to the contralateral hemisphere in 1. Conclusion: SAG patterns appear to be associated with the topography of the EZ in MRI-negative frontal lobe epilepsy and may have a useful role in preoperative assessment. Small focal cortical dysplasia not detected with MRI is often found on histopathological examination, particularly in the depth of the posterior part of the superior frontal sulcus and intermediate frontal sulcus, suggesting a specific developmental critical zone in these locations.

  15. Is the use of 55" LCD 3D screen practicable in large seminar to lecture hall size audiences? (United States)

    Ilgner, Justus; Sparrer, Ingo; Westhofen, Martin


    Introduction: The presentation of surgical contents to undergraduate medical students can be challenging, as the surgical approach is often different from the anatomist's perspective that is reproduced in textbooks. Although there are many options to record endoscopic, microscopic as well as "open" surgical procedures, presentation of contents still can be costly and entail a loss in picture quality including depth impression. Material and methods: We presented seven stereoscopic clips of 30 seconds to minute and 20 seconds each to 64 medical students (43 female / 21 male) as part of the "sensory organs" course module in 4th year; using one 55" LCD 3D screen with line-alternating, circular polarization. Students were asked for their subjective viewing impression and about their opinion on the usefulness of 3D presentations in medical lectures. Results: 63% of students returned their questionnaires completed. The main results (multiple answers allowed) were: 70% noted that 3D presentations made complex anatomy easier to comprehend from an unknown perspective, 48% would feel better motivated to learn surgical procedures, and 38% would generally prefer a 3D lecture to a 2D lecture, while 23% would not see any advantage of 3D presentations whatsoever. Conclusion: While the screen size compared to audience size was far from ideal, it gave medical students, who had not been exposed to surgical procedures in the operating theatre yet, an impression of general approach to microsurgery and how the choice of surgical approach in relation of vital structures can minimize trauma and unwanted effects to the patient. The availability of larger screens, however, may necessitate changes in production of 3D material from the microscope camera onward.

  16. [Readers' position against induced abortion]. (United States)


    Replies to the request by the Journal of Nursing on readers' positions against induced abortion indicate there is a definite personal position against induced abortion and the assistance in this procedure. Some writers expressed an emotional "no" against induced abortion. Many quoted arguments from the literature, such as a medical dictionary definition as "a premeditated criminally induced abortion." The largest group of writers quoted from the Bible, the tenor always being: "God made man, he made us with his hands; we have no right to make the decision." People with other philosophies also objected. Theosophical viewpoint considers reincarnation and the law of cause and effect (karma). This philosophy holds that induced abortion impedes the appearance of a reincarnated being. The fundamental question in the abortion problem is, "can the fetus be considered a human life?" The German anatomist Professor E. Bleckschmidt points out that from conception there is human life, hence the fertilized cell can only develop into a human being and is not merely a piece of tissue. Professional nursing interpretation is that nursing action directed towards killing of a human being (unborn child) is against the nature and the essence of the nursing profession. A different opinion states that a nurse cares for patients who have decided for the operation. The nurse doesn't judge but respects the individual's decision. Some proabortion viewpoints considered the endangering of the mother's life by the unborn child, and the case of rape. With the arguments against abortion the question arises how to help the woman with unwanted pregnancy. Psychological counseling is emphasized as well as responsible and careful assistance. Referral to the Society for Protection of the Unborn Child (VBOK) is considered as well as other agencies. Further reader comments on this subject are solicited.

  17. Sensitivity of a subject-specific musculoskeletal model to the uncertainties on the joint axes location. (United States)

    Martelli, Saulo; Valente, Giordano; Viceconti, Marco; Taddei, Fulvia


    Subject-specific musculoskeletal models have become key tools in the clinical decision-making process. However, the sensitivity of the calculated solution to the unavoidable errors committed while deriving the model parameters from the available information is not fully understood. The aim of this study was to calculate the sensitivity of all the kinematics and kinetics variables to the inter-examiner uncertainty in the identification of the lower limb joint models. The study was based on the computer tomography of the entire lower-limb from a single donor and the motion capture from a body-matched volunteer. The hip, the knee and the ankle joint models were defined following the International Society of Biomechanics recommendations. Using a software interface, five expert anatomists identified on the donor's images the necessary bony locations five times with a three-day time interval. A detailed subject-specific musculoskeletal model was taken from an earlier study, and re-formulated to define the joint axes by inputting the necessary bony locations. Gait simulations were run using OpenSim within a Monte Carlo stochastic scheme, where the locations of the bony landmarks were varied randomly according to the estimated distributions. Trends for the joint angles, moments, and the muscle and joint forces did not substantially change after parameter perturbations. The highest variations were as follows: (a) 11° calculated for the hip rotation angle, (b) 1% BW × H calculated for the knee moment and (c) 0.33 BW calculated for the ankle plantarflexor muscles and the ankle joint forces. In conclusion, the identification of the joint axes from clinical images is a robust procedure for human movement modelling and simulation.

  18. Lecture recording system in anatomy: possible benefit to auditory learners. (United States)

    Bacro, Thierry R H; Gebregziabher, Mulugeta; Ariail, Jennie


    The literature reports that using Learning Recording Systems (LRS) is usually well received by students but that the pedagogical value of LRS in academic settings remains somewhat unclear. The primary aim of the current study is to document students' perceptions, actual pattern of usage, and impact of use of LRS on students' grade in a dental gross and neuroanatomy course. Other aims are to determine if students' learning preference correlated with final grades and to see if other factors like gender, age, overall academic score on the Dental Aptitude Test (DAT), lecture levels of difficulty, type of lecture, category of lecture, or teaching faculty could explain the impact, if any, of the use of LRS on the course final grade. No significant correlation was detected between the final grades and the variables studied except for a significant but modest correlation between final grades and the number of times the students accessed the lecture recordings (r=0.33 with P=0.01). Also, after adjusting for gender, age, learning style, and academic DAT, a significant interaction between auditory and average usage time was found for final grade (P=0.03). Students who classified themselves as auditory and who used the LRS on average for fewer than 10 minutes per access, scored an average final grade of 16.43 % higher than the nonauditory students using the LRS for the same amount of time per access. Based on these findings, implications for teaching are discussed and recommendations for use of LRS are proposed. Copyright © 2013 American Association of Anatomists.

  19. The historical evolution of the understanding of the submandibular and sublingual salivary glands. (United States)

    Lydiatt, Daniel D; Bucher, Gregory S


    The discovery of the major salivary glands was primarily a story of the establishment of the glands major excretory ducts. Occurring during the Renaissance: religious, political, and philosophical considerations played a role in defining the structure's function. We describe the history and background of these political, religious, and philosophical factors. Next, we present a translation of the original texts, describing the establishment of the submandibular and sublingual salivary glands. We place these translations into historical context and comment on their naming propriety. Initially we translate the works of the 15th century anatomists. Next, we look at the discovery and description of the submandibular gland's duct by Thomas Wharton (1614-1673) in his landmark book, Adenographia sive glandularum totius corporis descriptio (Adenographia or the description of the glands of the entire body) (1656). Next, the somewhat unexpected discovery of the duct of the parotid gland by Nicholas Stenson (1638-1686) and his publication, De glandulis oris et novis earundum vasis (On the glands of the mouth and their new ducts) (1661), done primarily for his discussion of the submandibular and sublingual gland anatomy. Finally we outline the description and discussion by Caspar Bartholin (1655-1738), in De ductu salivali, hactenus non descripto observatio anatomica (Anatomical observation of a salivary duct not hitherto described) (1685) of the origin of the complex drainage system of the sublingual gland. The honor of naming these glands rested with the discoverer of their ducts. All original works were published in Latin, and we have translated these texts to more fully understand the author's perspectives and historical context for a more interesting and complete story.

  20. The effects of passive and active learning on student preference and performance in an undergraduate basic science course. (United States)

    Minhas, Paras Singh; Ghosh, Arundhati; Swanzy, Leah


    Active learning is based on self-directed and autonomous teaching methods, whereas passive learning is grounded in instructor taught lectures. An animal physiology course was studied over a two-year period (Year 1, n = 42 students; Year 2, n = 30 students) to determine the effects of student-led seminar (andragogical) and lecture (pedagogical) teaching methods on students' retention of information and performance. For each year of the study, the course was divided into two time periods. The first half was dedicated to instructor-led lectures, followed by a control survey in which the students rated the efficiency of pedagogical learning on a five-point Likert scale from one (strongly disagree) to five (strongly agree). During the second period, students engaged in andragogical learning via peer-led seminars. An experimental survey was then administered to students using the same scale as above to determine students' preferred teaching method. Raw examination scores and survey results from both halves of the course were statistically analyzed by ANOVA with Newman-Keuls multiple comparison test. By the end of the study, student preference for peer-led seminars increased [mean ± SD: (2.47 ± 0.94)/(4.03 ± 1.36), P students (68.8%) preferred a method that contained peer-led seminars and instructor-led lectures. These results may indicate that integration of active and passive learning into undergraduate courses may have greater benefit in terms of student preference and performance than either method alone.

  1. Mortality From Lymphohematopoietic Malignancies and Brain Cancer Among Embalmers Exposed to Formaldehyde (United States)

    Hauptmann, Michael; Stewart, Patricia A.; Lubin, Jay H.; Hornung, Richard W.; Herrick, Robert F.; Hoover, Robert N.; Fraumeni, Joseph F.; Blair, Aaron; Hayes, Richard B.


    Background Excess mortality from lymphohematopoietic malignancies, in particular myeloid leukemia, and brain cancer has been found in surveys of anatomists, pathologists, and funeral industry workers, all of whom may have worked with formaldehyde. We investigated the relation of mortality to work practices and formaldehyde exposure levels among these professionals to address cancer risk in the funeral industry. Methods Professionals employed in the funeral industry who died between January 1, 1960, and January 1, 1986, from lymphohematopoietic malignancies (n = 168) or brain tumors (n = 48) (ie, case subjects) were compared with deceased matched control subjects (n = 265) with regard to lifetime work practices and exposures in the funeral industry, which were obtained by interviews with next of kin and coworkers, and to estimated levels of formaldehyde exposure. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated by use of logistic regression. All statistical tests were two-sided. Results Mortality from myeloid leukemia increased statistically significantly with increasing number of years of embalming (P for trend = .020) and with increasing peak formaldehyde exposure (P for trend = .036). Compared with subjects who performed fewer than 500 lifetime embalmings, mortality from myeloid leukemia was elevated among those who performed embalmings for more than 34 years (OR = 3.9, 95% CI = 1.2 to 12.5, P = .024), who performed more than 3068 embalmings (OR = 3.0, 95% CI = 1.0 to 9.2, P = .057), and those whose estimated cumulative formaldehyde exposure exceeded 9253 parts per million–hours (OR = 3.1; 95% CI = 1.0 to 9.6, P = .047). These exposures were not related to other lymphohematopoietic malignancies or to brain cancer. Conclusion Duration of embalming practice and related formaldehyde exposures in the funeral industry were associated with statistically significantly increased risk for mortality from myeloid leukemia.

  2. Comparison of modified Thiel embalming and ethanol-glycerin fixation in an anatomy environment: Potentials and limitations of two complementary techniques. (United States)

    Hammer, Niels; Löffler, Sabine; Bechmann, Ingo; Steinke, Hanno; Hädrich, Carsten; Feja, Christine


    Thiel-fixed specimens have outstandingly lifelike visual and haptic properties. However, the original Thiel method is expensive and requires an elaborate setup. It is therefore of principal interest to modify the Thiel method in order to make it available to a broader user group. A modified Thiel embalming method will be described in detail and compared to ethanol-glycerin fixation with the help of illustrative examples. The visual properties, haptic properties, the usability for performing histological investigations, costs and potential health aspects will be considered. Tissues fixed with the modified Thiel technique gave results similar to the original method, providing more realistic visual and haptic properties than ethanol-glycerin embalming. However, Thiel fixation is significantly more expensive and requires more precautions to minimize potential health hazards than ethanol-glycerin-fixed tissues. In contrast to ethanol-glycerin-fixed specimens, the Thiel-fixed specimens are not suitable for histological investigations. Both modes of fixation are inappropriate for biomechanical testing. Modified Thiel embalming simplifies the availability of body donors with lifelike properties and has cost-saving advantages to the original technique. Thiel-embalmed body donors are ideally suited for clinical workshops but have restrictions for student dissection courses in facilities with limited storage space, air circulation or technical staff. Vice versa, ethanol-glycerin-fixed body donors are well suited for student dissection courses in such an environment but are limited in their use for clinical workshops. Modified Thiel embalming therefore ideally complements ethanol-glycerin fixation in order to provide customized solutions for clinical workshops and student dissection courses in a wide range of applications. © 2014 American Association of Anatomists.

    Full Text Available Dr. Gunther von Hagens developed plastination as a technique of tissue preservation in 1977. He used a delicate method of forced impregnation with curable polymers like silicone, epoxy or polyester resins for preservation of anatomical specimens. With plastination, every part of a biological tissue is treated, preserving it for educational purposes. Hence, there are vast applications in the medical field. We set out to survey the knowledge and opinion of lecturers of anatomy about plastinated specimen use in medical schools through the administration of questionnaires to respondents who participated at the Society of Experimental and Clinical Anatomists of Nigeria (SECAN conference in 2011. It was found that 50.0% and 23.75% of respondents respectively, had their masters and doctorate degrees in Anatomy. Less than 8.0% utilised plastination as a tool for teaching as against 40% (plastic models, 36.25% (cadavers and 15.0% (pathology pots. Conventional methods such as fixation by immersion (15.0% and embalming (52.5% with formaldehyde were commonly used for long term preservation of tissues in their various institutions. These methods were found to be less costly (25.0%, easy to use (56.25% and the only method (12.25% available, even though they posed some health hazards (96.0%. Whilst only 6.25% of the respondents did not know anything about plastination, 93.75% were aware of it. The advocacy for preservation of tissues by plastination has been gradual in developed countries. We recommend the use of plastinates in medical schools in Nigeria.

    Full Text Available BACKGROUND The mediastinum is demarcated by the pleural cavities laterally, the thoracic inlet superiorly and the diaphragm inferiorly. It is further divided into anterior, middle and posterior compartments by many anatomists. 1 CT imaging allows early diagnosis and more specific characterization of anterior mediastinal masses than is possible with plain film radiographs. This study describes state-of-the-art CT imaging of the mediastinum. 1 Detection, diagnosis, staging, and follow-up of anterior mediastinal masses is important and has been significantly improved with CT imaging. MATERIALS AND METHODS The study was conducted on 50 patients on SIEMENS 16 Slice CT SCAN Machine in our department of Radio-diagnosis at C. U. Shah Medical College and Hospital from May 2014 to Oct 2015. The patients were chosen on the basis of clinical findings and suspected mediastinal lesion on X-rays. The study is completely an observational type of study. RESULTS On the basis of our study, it was found out that maximum number of patients were of more than 61 years of age with common symptoms of cough with chest pain and breathlessness. Common sites of mediastinal pathology is in middle compartment with maximum number of lesions were of malignant nature either extending from perihilar region or in mediastinal proper some of them showing metastasis. Most of the lesions were solid in nature showing heterogeneous contrast enhancement showing vascular and adjacent structure involvement. The common benign lesions were goiter, hernia and infective collection. CONCLUSION The mediastinum represents a wide variety of pathologies ranging from congenital lesions to malignant tumours. Conventional radiographs have limited spectrum in diagnosing mediastinal pathologies, thus CT plays an important role in proper delineation of the lesion and defining the anatomical details of the surrounding structures involved by the lesion. With the help of CT and its excellent high resolution

  5. Towards the sensory nature of the carotid body: Hering, De Castro and Heymans

    Directory of Open Access Journals (Sweden)

    Fernando De Castro


    Full Text Available The carotid body or glomus caroticum is a chemosensory organ bilaterally located between the external and internal carotid arteries. Although known by anatomists since the report included by Von Haller and Taube in the mid XVIIIth century, its detailed study started the first quarter of the XXth. The Austro-German physiologist Heinrich E. Hering studied the cardio-respiratory reflexes searched for the anatomical basis of this reflex in the carotid sinus, while the Ghent School leaded by the physio-pharmacologists Jean-François Heymans and his son Corneille focussed in the cardio-aortic reflexogenic region. In 1925, Fernando De Castro, one of the youngest and more brilliant disciples of Santiago Ramón y Cajal at the Laboratorio de Investigaciones Biológicas (Madrid, Spain, profited from some original novelties in histological procedures to study the fine structure and innervation of the carotid body. De Castro unravelled them in a series of scientific papers published between 1926 and 1929, which became the basis to consider the carotid body as a sensory receptor (or chemoreceptor to detect the chemical changes in the composition of the blood. Indeed, this was the first description of arterial chemoreceptors. Impressed by the novelty and implications of the work of De Castro, Corneille Heymans invited the Spanish neurologist to visit Ghent on two occasions (1929 and 1932, where both performed experiences together. Shortly after, Heymans visited De Castro at the Instituto Cajal (Madrid. From 1932-33, Corneille Heymans focused all his attention on the carotid body his physiological demonstration of De Castro’s hypothesis regarding chemoreceptors was awarded with the Nobel Prize in Physiology or Medicine in 1938, just when Spain was immersed in its catastrophic Civil War.

  6. Using embryology screencasts: a useful addition to the student learning experience? (United States)

    Evans, Darrell J R


    Although podcasting has been a well used resource format in the last few years as a way of improving the student learning experience, the inclusion of enhanced audiovisual formats such as screencasts has been less used, despite the advantage that they work well for both visual and auditory learners. This study examines the use of and student reaction to a set of screencasts introduced to accompany embryology lectures within a second year module at Brighton and Sussex Medical School. Five mini-lecture screencasts and one review quiz screencast were produced as digital recordings of computer screen output with audio narration and released to students via the managed learning environment (MLE). Analysis of server log information from the MLE showed that the screencasts were accessed by many of the students in the cohort, although the exact numbers were variable depending on the screencast. Students accessed screencasts at different times of the day and over the whole of the access period, although maximum downloads were predictably recorded leading up to the written examination. Quantitative and qualitative feedback demonstrated that most students viewed the screencasts favorably in terms of usefulness to their learning, and end-of-module written examination scores suggest that the screencasts may have had a positive effect on student outcome when compared with previous student attainment. Overall, the development of a series of embryology screencasts to accompany embryology lecture sessions appears to be a useful addition to learning for most students and not simply an innovation that checks the box of "technology engagement."

  7. Investigating the use of quick response codes in the gross anatomy laboratory. (United States)

    Traser, Courtney J; Hoffman, Leslie A; Seifert, Mark F; Wilson, Adam B


    The use of quick response (QR) codes within undergraduate university courses is on the rise, yet literature concerning their use in medical education is scant. This study examined student perceptions on the usefulness of QR codes as learning aids in a medical gross anatomy course, statistically analyzed whether this learning aid impacted student performance, and evaluated whether performance could be explained by the frequency of QR code usage. Question prompts and QR codes tagged on cadaveric specimens and models were available for four weeks as learning aids to medical (n = 155) and doctor of physical therapy (n = 39) students. Each QR code provided answers to posed questions in the form of embedded text or hyperlinked web pages. Students' perceptions were gathered using a formative questionnaire and practical examination scores were used to assess potential gains in student achievement. Overall, students responded positively to the use of QR codes in the gross anatomy laboratory as 89% (57/64) agreed the codes augmented their learning of anatomy. The users' most noticeable objection to using QR codes was the reluctance to bring their smartphones into the gross anatomy laboratory. A comparison between the performance of QR code users and non-users was found to be nonsignificant (P = 0.113), and no significant gains in performance (P = 0.302) were observed after the intervention. Learners welcomed the implementation of QR code technology in the gross anatomy laboratory, yet this intervention had no apparent effect on practical examination performance. © 2014 American Association of Anatomists.

  8. Student perceptions of independent versus facilitated small group learning approaches to compressed medical anatomy education. (United States)

    Whelan, Alexander; Leddy, John J; Mindra, Sean; Matthew Hughes, J D; El-Bialy, Safaa; Ramnanan, Christopher J


    The purpose of this study was to compare student perceptions regarding two, small group learning approaches to compressed (46.5 prosection-based laboratory hours), integrated anatomy education at the University of Ottawa medical program. In the facilitated active learning (FAL) approach, tutors engage students and are expected to enable and balance both active learning and progression through laboratory objectives. In contrast, the emphasized independent learning (EIL) approach stresses elements from the "flipped classroom" educational model: prelaboratory preparation, independent laboratory learning, and limited tutor involvement. Quantitative (Likert-style questions) and qualitative data (independent thematic analysis of open-ended commentary) from a survey of students who had completed the preclerkship curriculum identified strengths from the EIL (promoting student collaboration and communication) and FAL (successful progression through objectives) approaches. However, EIL led to student frustration related to a lack of direction and impaired completion of objectives, whereas active learning opportunities in FAL were highly variable and dependent on tutor teaching style. A "hidden curriculum" was also identified, where students (particularly EIL and clerkship students) commonly compared their compressed anatomy education or their anatomy learning environment with other approaches. Finally, while both groups highly regarded the efficiency of prosection-based learning and expressed value for cadaveric-based learning, student commentary noted that the lack of grade value dedicated to anatomy assessment limited student accountability. This study revealed critical insights into small group learning in compressed anatomy education, including the need to balance student active learning opportunities with appropriate direction and feedback (including assessment). © 2015 American Association of Anatomists.

  9. [Anatomia practica: features from the history of early patho-anatomy]. (United States)

    Jensen, Olaf Myhre


    Since the anatomy school of Alexandria during the fourth og third century before Christ dissection of the human body seems not to have been practiced until late Medieval or early Renaissance period, undoubtedly due to ethical and religious aversions. The teaching of anatomy was based on Galen using animal dissection. In the fourteenth and fifteenth centuries, however, anatomical examinations of the human body slowly began, seemingly for the purpose of describing both the normal structure and the abnormal structure caused by diseases, maldevelopment or trauma. This latter branch of anatomy was called practical, medical or correlative anatomy and corresponds to what we today name as patho-anatomy. Antonio Benivieni of Florence (1442-1502) is the first one to collect (and publish) a series of clinical observations some of which could be correlated to post mortem findings. It is unknown, however, whether the autopsies were performed by himself; and there is no mentioning of technique or circumstances for sectioning. Studies of the dead body by incision for the purpose of displaying diseased organs (autopsy) seem to have been an accepted practice for which relatives consented in those days. Other medical doctors in the years to follow, as for instance Fernel (1485-1558) in Paris, Eustachius (1524-1574) in Rome, Felix Plater (1536-1614) in Basle and Th. Bartholin (1616-1680) in Copenhagen have used the anatomical method for the study of diseases. Further, Schenck (1530-1598) in Freiburg and Bonet (1620-1689) in Genéva collected and published large series of clinical symptoms which had been related to post mortem findings dating back to ancient observers. This is the scientific background for anatomists as Morgagni, Lieutaud, Baillie, Bichât and others who founded the morbid anatomy on which the study of disease flourished in the classical patho-anatomical era of the nineteenth century with names as Rokitanski and Virchow.

  10. Case study of Berengario da Carpi and Lorenzo de' Medici. (United States)

    Lippi, D


    Jacopo Berengario da Carpi (c.1460-c.1530) made several important advances in anatomy, being universally considered the founder of 'animated anatomy' (anatomia animata). In addition to being a famous anatomist, Berengario was also a highly regarded surgeon. One of his famous clients was Lorenzo de' Medici, Duke of Urbino (1492-1519). In 1517, Lorenzo suffered a skull injury from an harquebus shot and Berengario was asked to come to his bedside. Lorenzo's case gave Berengario the opportunity to write his Tractatus de Fractura Calve sive Cranei, published in Bologna by Gerolamo Benedetti in 1518. Berengario addressed his treatise to Lorenzo himself. This illustrated monograph was the most original neurosurgical treatise at that time, as Berengario was able to cite both from contemporary information and from his own direct observation all possible kinds of skull fracture, including the relationship between the site of the lesions and the resulting neurological effects. At the end of the book, Berengario explained and illustrated the surgical equipment to be used in each case, depicting a drill previously unseen in a medical volume and providing the recipe for a human dressing, a kind of poultice made of mummified human remins, to be applied regularly to wounds. Lorenzo de' Medici died in 1519 and was buried in the Church of San Lorenzo in Florence. His corpse was exhumed in 1875 and 1947. The casts of his skull made on those occasions are now preserved in the museums of Florence University, and clearly show evidence of the wound.

  11. Participation in asynchronous online discussion forums does improve student learning of gross anatomy. (United States)

    Green, Rodney A; Farchione, Davide; Hughes, Diane L; Chan, Siew-Pang


    Asynchronous online discussion forums are common in blended learning models and are popular with students. A previous report has suggested that participation in these forums may assist student learning in a gross anatomy subject but it was unclear as to whether more academically able students post more often or whether participation led to improved learning outcomes. This study used a path model to analyze the contribution of forum participation, previous academic ability, and student campus of enrolment to final marks in a multicampus gross anatomy course for physiotherapy students. The course has a substantial online learning management system (LMS) that incorporates asynchronous forums as a learning tool, particularly to answer learning objectives. Students were encouraged to post new threads and answer queries in threads started by others. The forums were moderated weekly by staff. Discussion forums were the most used feature of the LMS site with 31,920 hits. Forty-eight percent of the students posted at least once with 186 threads initiated by students and a total of 608 posts. The total number of posts made a significant direct contribution to final mark (P = 0.008) as did previous academic ability (P = 0.002). Although campus did not contribute to final mark, there was a trend for students at the campus where the course coordinator was situated to post more often than those at the other campus (P = 0.073). These results indicate that asynchronous online discussion forums can be an effective tool for improving student learning outcomes as evidenced by final marks in gross anatomy teaching.

  12. Assessing student engagement and self-regulated learning in a medical gross anatomy course. (United States)

    Pizzimenti, Marc A; Axelson, Rick D


    In courses with large enrollment, faculty members sometimes struggle with an understanding of how individual students are engaging in their courses. Information about the level of student engagement that instructors would likely find most useful can be linked to: (1) the learning strategies that students are using; (2) the barriers to learning that students are encountering; and (3) whether the course materials and activities are yielding the intended learning outcomes. This study drew upon self-regulated learning theory (SRL) to specify relevant information about learning engagement, and how the measures of particular scales might prove useful for student/faculty reflection. We tested the quality of such information as collected via the Motivated Strategies for Learning Questionnaire (MSLQ). MSLQ items were administered through a web-based survey to 150 students in a first-year medical gross anatomy course. The resulting 66 responses (44% response rate) were examined for information quality (internal reliability and predictive validity) and usefulness of the results to the course instructor. Students' final grades in the course were correlated with their MSLQ scale scores to assess the predictive validity of the measures. These results were consistent with the course design and expectations, showing that greater use of learning strategies such as elaboration and critical thinking was associated with higher levels of performance in the course. Motivation subscales for learning were also correlated with the higher levels of performance in the course. The extent to which these scales capture valid and reliable information in other institutional settings and courses needs further investigation. © 2014 American Association of Anatomists.

  13. Enhancement of anatomical learning and developing clinical competence of first-year medical and allied health profession students. (United States)

    Keim Janssen, Sarah A; VanderMeulen, Stephane P; Shostrom, Valerie K; Lomneth, Carol S


    Hands-on educational experiences can stimulate student interest, increase knowledge retention, and enhance development of clinical skills. The Lachman test, used to assess the integrity of the anterior cruciate ligament (ACL), is commonly performed by health care professionals and is relatively easy to teach to first-year health profession students. This study integrated teaching the Lachman test into a first-year anatomy laboratory and examined if students receiving the training would be more confident, competent, and if the training would enhance anatomical learning. First-year medical, physician assistant and physical therapy students were randomly assigned into either the intervention (Group A) or control group (Group B). Both groups received the course lecture on knee anatomy and training on how to perform the Lachman test during a surface anatomy class. Group A received an additional 15 minutes hands-on training for the Lachman test utilizing a lightly embalmed cadaver as a simulated patient. One week later, both groups performed the Lachman test on a lightly embalmed cadaver and later completed a post-test and survey. Students with hands-on training performed significantly better than students with lecture-only training in completing the checklist, a post-test, and correctly diagnosing an ACL tear. Students in Group A also reported being more confident after hands-on training compared to students receiving lecture-only training. Both groups reported that incorporating clinical skill activities facilitated learning and created excitement for learning. Hands-on training using lightly embalmed cadavers as patient simulators increased confidence and competence in performing the Lachman test and aided in learning anatomy. © 2013 American Association of Anatomists.

  15. Energy Homeostasis in Monotremes

    Directory of Open Access Journals (Sweden)

    Stewart C. Nicol


    Full Text Available In 1803, the French anatomist Étienne Geoffroy Saint-Hilaire decided that the newly described echidna and platypus should be placed in a separate order, the monotremes, intermediate between reptiles and mammals. The first physiological observations showed monotremes had low body temperatures and metabolic rates, and the consensus was that they were at a stage of physiological development intermediate between “higher mammals” and “lower vertebrates.” Subsequent studies demonstrated that platypuses and echidnas are capable of close thermoregulation in the cold although less so under hot conditions. Because the short-beaked echidna Tachyglossus aculeatus, may show very large daily variations in body temperature, as well as seasonal hibernation, it has been suggested that it may provide a useful model of protoendotherm physiology. Such analysis is complicated by the very significant differences in thermal relations between echidnas from different climates. In all areas female echidnas regulate Tb within 1°C during egg incubation. The lactation period is considered to be the most energetically expensive time for most female mammals but lactating echidnas showed no measurable difference in field metabolic rate from non-lactating females, while the lactation period is more than 200 days for Kangaroo Island echidnas but only 150 days in Tasmania. In areas with mild winters echidnas show reduced activity and shallow torpor in autumn and early winter, but in areas with cold winters echidnas enter true hibernation with Tb falling as low as 4.5°C. Monotremes do not possess brown adipose tissue and maximum rates of rewarming from hibernation in echidnas were only half those of marmots of the same mass. Although echidnas show very large seasonal variations in fat stores associated with hibernation there is no relationship between plasma leptin and adiposity. Leptin levels are lowest during post-reproductive fattening, supporting suggestions that in

    Background: Radiation therapy treatment planning has advanced over the past 2 decades, with increased emphasis on 3-dimensional imaging for target and organ-at-risk (OAR) delineation. Recent studies suggest a need for improved resident instruction in this area. We developed and evaluated an intensive national educational course (“boot camp”) designed to provide dedicated instruction in site-specific anatomy, radiology, and contouring using a multidisciplinary (MDT) approach. Methods: The anatomy and radiology contouring (ARC) boot camp was modeled after prior single-institution pilot studies and a needs-assessment survey. The boot camp incorporated joint lectures from radiation oncologists, anatomists, radiologists, and surgeons, with hands-on contouring instruction and small group interactive seminars using cadaveric prosections and correlative axial radiographs. Outcomes were evaluated using pretesting and posttesting, including anatomy/radiology multiple-choice questions (MCQ), timed contouring sessions (evaluated relative to a gold standard using Dice similarity metrics), and qualitative questions on satisfaction and perceived effectiveness. Analyses of pretest versus posttest scores were performed using nonparametric paired testing. Results: Twenty-nine radiation oncology residents from 10 Canadian universities participated. As part of their current training, 29%, 75%, and 21% receive anatomy, radiology, and contouring instruction, respectively. On posttest scores, the MCQ knowledge scores improved significantly (pretest mean 60% vs posttest mean 80%, P<.001). Across all contoured structures, there was a 0.20 median improvement in students' average Dice score (P<.001). For individual structures, significant Dice improvements occurred in 10 structures. Residents self-reported an improved ability to contour OARs and interpret radiographs in all anatomic sites, 92% of students found the MDT format effective for their learning, and 93% found the boot camp

  17. Clinical detectable tension in the growing body: new and revisited signs in clinical examination in children with postural problems and spinal deformities. Restoration of lordosis on the thoracolumbar junction can correct sagittal and coronal plane deformity; a new (revisited) linked approach on the treatment and etiology of adolescent spinal deformities. (United States)

    Unclear etiology in scoliotic and kyphotic deformities of the spine is responsible for uncertainty in treatment options. Normal all-day factors can be of importance. Newly developed or revisited clinical examination of sitting and supine children and consequent testing of neuro-muscular tightness shows to be useful in understanding the different spinal deformations and postural problems during growth and point to neuromuscular tension in growth. The goal is: -Better understanding of the role and individual characteristics of the central nervous system, especially the cord and roots in proper and improper growth of the human spine. -Clarifying that preservation of lordosis and good function at the thoracolumbar junction at the end of growth can be of value for normal configuration and function of the spine in adult life. -Present obvious important and consistent clinical observations in children in sitting and supine position with early and advanced adolescent deformities, by photographic studies and video fragments. Use of work on growth and deformation of the spine by Milan Roth on uncoupled neuro-osseous growth and other historical literature. -Relate these clinical findings and background literature with common knowledge about adolescent spinal deformities and mechanical laws on tensile and compressive forces in structures. Overview of relevant clinical tests in the growing child presented with deformities show possible correlation with the proposed internal balancing problem (uncoupled neuro-osseous growth) researched by Roth. Concomitant radiological and MRI signs are shown. Around 1900 most orthopaedic surgeons and anatomists saw relationship between the new habitude of children to sit for prolonged periods in schools and spinal deformities. A physiological explanation as adaptations needed by the total neuromuscular system ("the growing system") was widely postulated (Hueter-Volkmann principle) and subject in research but a concise theory was not achieved

    significant sexual dimorphism. Thus, both metric and non-metric features of clavicle can have decisive role in forensic identifications and clinical interventions. Present results would be of great significance for anatomists, orthopedicians, surgeons and the forensic anthropologists in their professional endeavors.

  19. If bone is the answer, then what is the question? (United States)

    Huiskes, R


    In the 19th century, several scientists attempted to relate bone trabecular morphology to its mechanical, load-bearing function. It was suggested that bone architecture was an answer to requirements of optimal stress transfer, pairing maximal strength to minimal weight, according to particular mathematical design rules. Using contemporary methods of analysis, stress transfer in bones was studied and compared with anatomical specimens, from which it was hypothesised that trabecular architecture is associated with stress trajectories. Others focused on the biological processes by which trabecular architectures are formed and on the question of how bone could maintain the relationship between external load and architecture in a variable functional environment. Wilhelm Roux introduced the principle of functional adaptation as a self-organising process based in the tissues. Julius Wolff, anatomist and orthopaedic surgeon, entwined these 3 issues in his book The Law of Bone Remodeling (translation), which set the stage for biomechanical research goals in our day. 'Wolff's Law' is a question rather than a law, asking for the requirements of structural optimisation. In this article, based on finite element analysis (FEA) results of stress transfer in bones, it is argued that it was the wrong question, putting us on the wrong foot. The maximal strength/minimal weight principle does not provide a rationale for architectural formation or adaptation; the similarity between trabecular orientation and stress trajectories is circumstantial, not causal. Based on computer simulations of bone remodelling as a regulatory process, governed by mechanical usage and orchestrated by osteocyte mechanosensitivity, it is shown that Roux's paradigm, conversely, is a realistic proposition. Put in a quantitative regulatory context, it can predict both trabecular formation and adaptation. Hence, trabecular architecture is not an answer to Wolff's question, in the sense of this article's title

  20. Evaluation of an animation tool developed to supplement dental student study of the cranial nerves. (United States)

    The structure/function of the cranial nerves is a core topic for dental students. However, due to the perceived complexity of the subject, it is often difficult for students to develop a comprehensive understanding of key concepts using textbooks and models. It is accepted that the acquisition of anatomical knowledge can be facilitated by visualisation of structures. This study aimed to develop and assess a novel cranial nerve animation as a supplemental learning aid for dental students. A multidisciplinary team of anatomists, neuroscientists and a computer scientist developed a novel animation depicting the cranial nerves. The animation was viewed by newly enrolled first-year dental students, graduate entry dental students (year 1) and dental hygiene students (year 1). A simple life scenario employing the use of the cranial nerves was developed using a cartoon-type animation with a viewing time of 3.58 minutes. The animation was developed with emphasis on a life scenario. The animation was placed online for 2 weeks with open access or viewed once in a controlled laboratory setting. Questionnaires were designed to assess the participants' attitude towards the animation and their knowledge of the cranial nerves before and after visualisation. This study was performed before the delivery of core lectures on the cranial nerves. Our findings indicate that the use of the animation can act as a suppleme
