  1. 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...

  2. The anatomist Hans Elias: A Jewish German in exile. (United States)

    Hildebrandt, S


    Hans Elias (1907 to 1985) was an anatomist, an educator, a mathematician, a cinematographer, a painter, and a sculptor. Above all, he was a German of Jewish descent, who had to leave his home country because of the policies of the National Socialist (NS) regime. He spent his life in exile, first in Italy and then in the United States. His biography is exemplary for a generation of younger expatriates from National Socialist Germany who had to find a new professional career under difficult circumstances. Elias was a greatly productive morphologist whose artistic talent led to the foundation of the new science of stereology and made him an expert in scientific cinematography. He struggled hard to fulfill his own high expectations of himself in terms of his effectiveness as a scientist, educator, and politically acting man in this world. Throughout his life this strong-willed and outspoken man never lost his great fondness for Germany and many of its people, while reserving some of his sharpest criticism for fellow anatomists who were active in National Socialist Germany, among them his friend Hermann Stieve, Max Clara, and Heinrich von Hayek. Hans Elias' life is well documented in his unpublished diaries and memoirs, and thus allows fresh insights into a time period when some anatomists were among the first victims of NS policies and other anatomists became involved in the execution of such policies.

  3. 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. PMID:24753363

  4. 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. PMID:25577205

  6. Getting back together after a break-up: Relationship advice for anatomists and surgeons. (United States)

    Phitayakorn, Roy; Lachman, Nirusha


    The "surgeon-anatomist" was originally a single individual who self-pursued knowledge and understanding of anatomy as the foundation for successful surgical outcomes. However, recent advances in medical education have ironically led to the separation of anatomy and surgery. This physical and emotional "divorce" of anatomists and surgeons into separate individuals has created several critical educational issues for medical and surgical educators including a general lack of anatomical knowledge in medical students and misalignment of graduate medical education procedural specialty training with the Accreditation Council of Graduate Medical Education Core Competencies and now the Next Accreditation System. There are numerous opportunities for anatomists and surgeons to work together to improve educational instruction of established difficult anatomical regions, procedural training, or even develop new techniques and procedures. Similarly, anatomists with specialized training in medical education would be invaluable partners to ensure that procedural assessments align with instructional technologies for truly longitudinal curricula that starts at the medical student level, but stops at the patient outcomes of attending surgeons. This mutually beneficial relationship would be similar to multidisciplinary care teams and current surgeon and PhD/EdD partnerships. The restoration of the relationship between anatomists and surgeons would be invaluable to surgical education and remains an exciting research opportunity. PMID:26174432

  7. 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.

  8. Engaging with plastination and the Body Worlds phenomenon: a cultural and intellectual challenge for anatomists. (United States)

    Jones, D Gareth; Whitaker, Maja I


    Body Worlds, the international plastination phenomenon, has proved immensely popular with audiences worldwide. Never before has the human body been exposed to public gaze in such an accessible and intriguing manner. Dissected body parts feature alongside whole-body plastinates with their life-like poses ranging from those with Renaissance motifs to others with highly contemporary themes. However, the exhibitions and their creator, Gunther von Hagens, have astounded many, including anatomists, some of whom find the unconventional display of human bodies unethical and offensive. The voyeuristic nature of Body Worlds and the uneasy balance between entertainment and education have proved problematic for anatomists. Von Hagens himself is a polarizing figure, pursuing his dream of "democratizing anatomy" with little regard for the conventions of academia. While valid ethical objections can be raised against some aspects of the exhibitions, we argue that wholesale rejection of them is unwarranted. In arriving at this conclusion we assess the ethical and educational issues involved. We divide the whole-body plastinates into four categories, ranging from those illustrating structural and functional relationships to those with artistic and humanistic aspirations rather than anatomical ones. We conclude that anatomists need to face up to the opportunities and challenges posed by the Body Worlds phenomenon, utilizing what is being presented to the general public and adapting this in teaching and research.

  9. 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. PMID:26208340

  10. Dr Nicolaes Tulp of Amsterdam, 1593-1674: anatomist and doctor of medicine. (United States)

    Mellick, Sam A


    The renowned Dr Nicolaes Tulp of seventeenth century was a practising surgeon and physician, a civic leader and an anatomist who was appointed Praelector in Anatomy to regularize public dissections, and he was also charged by the Surgeons' Guild to apprentice surgeons. Rembrandt's famous painting 'The Anatomy of Dr Tulp' brought growing recognition not only to the painter for his artistry, but also to the surgeon for it introduced a new dimension into anatomical paintings by displaying both anatomical detail and muscle function. Tulp's interests included botany, drug therapy and the production of the official Dutch Pharmacopoea. In civic affairs too, he played an important role, becoming the Mayor of Amsterdam as well as a judge - he was indeed a most noteworthy citizen of his time. PMID:17973671

  11. Iulius Casserius: revolutionary anatomist, teacher and pioneer of the sixteenth and seventeenth century. (United States)

    Wysocki, Michał; Saganiak, Karolina; Zwinczewska, Helena; Roy, Joyeeta; Tomaszewski, Krzysztof A; Walocha, Jerzy A


    The demand for anatomical illustrations in the early modern period coincided with a scientific revolution. Starting out as a servant, Iulius Casserius became a great anatomist, who challenged the Galenic doctrine. The aim of this paper is to honor his memory and recreate the stylism of his anatomical illustrations. Online databases were searched for articles and original works. A medical graphic designer then recreated the figures presented in the article. Casserius was born around 1552. After moving to Padua, he served Fabricius in performing dissections. Obtaining his medical degree, he began working as an anatomical dissector and surgeon, later giving private anatomy lectures to students. He published De Vocis Auditusque and Pentaestheseion, and then became the lecturer of Surgery. In 1616, Casserius started his first Anatomy course and then died suddenly, at the height of his career. From the sixteenth century, illustrative techniques began focusing less upon artistry in favor of precise depictions of anatomical structures. Fabricius is considered to have used a strict scientific approach to illustrations for the first time. Anatomists of subsequent generations would still frequently use artistry in illustrations. Despite Casserius' mixed accuracy and artistry, his plates mark a new epoch in anatomic representation. Casserius left numerous eponyms and depicted, for the first time, many anatomical structures. Reprints in textbooks in the centuries following show convincing evidence of his success. Casserius contributed to medical education by taking the theatricality out of anatomy. Our article is a tribute to Casserius's achievements and depicts the revolution brought forth by a pioneer of his times. PMID:26783080

  12. Gunther von Hagens and Body Worlds part 2: The anatomist as priest and prophet. (United States)

    Moore, Charleen M; Brown, C Mackenzie


    Part 1 of this two-part series highlighted tensions between the anatomical quest for scientific knowledge about the human interior and artistic representations of the anatomized body, contrasting the roles of Goethe's scientific Prosektor and humanistic Proplastiker-roles disturbingly fused in Gunther von Hagens. Part 2 first examines religious interpretations of the human body that fuel the tensions manifest in anatomy art. The body in Western cultures is a sacred text amenable to interpretation as handiwork of God, habitation for the soul, and vehicle for resurrection. As handiwork of God the body beckons the anatomist's scalpel, helping establish dissection as the hallmark of Western medicine. The body as divinely designed machine encompasses the idea of an indwelling soul expressing its will in actions mediated through the intricate network of muscles-an understanding reflected in the oft occurring muscle men of early anatomical textbooks. Interconnections of body and soul in medieval somatic spirituality are examined with reference to ideas of resurrection and their impact on anatomical illustration. Part 2 concludes with consideration of von Hagens as priest and prophet, culminating in the Promethean impulse that recognizes not God but ourselves as proper owners and molders of our destiny, embodied in the plastinator's visionary quest to create the superhuman.

  13. Fighting for Anatomy. Overview regarding two prestigious Romanian anatomists of the 20th century: Victor Papilian and Grigore T. Popa. (United States)

    Bârsu, Cristian


    During many centuries, the progress of Anatomy was based on the perseverant and laborious activities done by anatomists. Their work can be considered as a fight for Anatomy. A particular problem arouse when this fight is excessively done and it limits the ability to correctly analyze the contribution made by other scientists in the same domain. This situation was identified at different personalities who lived in the same time and were involved in the same fundamental field of research. If, theoretically, the similarities between scientists should get them closer, in order to have a better communication, the antagonisms can lead them to rivalry. Our paper exemplifies a historical case in which the personages are Victor Papilian (1888-1956) and Grigore T. Popa (1892-1948). The resemblances between these two famous Romanian anatomists from the first half of the 20th century induced an evident scientific rivalry. Papilian and Popa brought a significant contribution in anatomy. Each of them was very much appreciated by his students. It is interesting that both of them had achievements in literature. We present the reasons of their disagreement and its consequences. Paradoxically, not the contrasts, but the resemblances between their strong characters produced a sort of animosity between them. This attitude diminished in time and their successors - Ioan Albu from the Cluj Faculty of Medicine and Ion Iancu from the Jassy Faculty of Medicine - had a long lasting and successful cooperation.

  14. The influence of the final cause doctrine on anatomists of the sixteenth and seventeenth centuries concerning selected anatomical structures of the head and neck. (United States)

    Lydiatt, Daniel D; Bucher, Gregory S


    The Doctrine of Final Cause, taken from Aristotle's "causes" and modified by Claudius (Aelius) Galen (of Pergamon) stated that for an anatomical part to exist it must have a "cause," not an end point, but a purpose or goal, natural or divine. This affected the renaissance anatomist's thinking. We explore this doctrine's relationship with human head and neck anatomy from antiquity's Aristotle and Galen, and the leading renaissance anatomists from the 16th and 17th centuries. Their relevant writings were influenced by religious and political beliefs and varied from humanistic to reactionary. Tracing anatomical controversies through these works reveal the humanism of Vesalius and others as paralleling the humanists of art and literature. These controversies illustrate how the body was used to demonstrate function, uses, and causes from higher sources. Humanists advanced the social, philosophical, intellectual, literary, and medical/anatomical thoughts of this period. They stood between the Christian church of the Middle Ages and modern science. Like religion, medicine and anatomy had its own revealed sources of knowledge and had sacred texts like Galen's. Vesalius' the Fabrica and the woodcuts established suddenly the beginning of modern observational science and art as the direct and faithful representation of natural phenomena. They displayed anatomy such that others could understand, including errors of Galen, bringing Vesalius into ecclesiastical conflict. Evolutionary scientists today see mutations as favorable or unfavorable depending on the environment. Mutations are random or directed by divine plan, according to perspectives of this ancient debate. PMID:22806933

  15. ["The first stages of the human egg" by Auguste d'Eternod published one hundred years ago in the Comptes Rendus de l'Association des Anatomistes]. (United States)

    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. PMID:24797922

  16. An artificial neuro-anatomist

    International Nuclear Information System (INIS)

    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.)

  19. 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 tian (heavenly/superior), xia (below/inferior), liao (bone-hole), fei (flying), wei (bend), and 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.

  2. 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.

These next-generation resources should influence traditional concept represen...

  7. [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. PMID:22338488

  9. The digital anatomist information system and its use in the generation and delivery of Web-based anatomy atlases. (United States)

    Brinkley, J F; Bradley, S W; Sundsten, J W; Rosse, C


    Advances in network and imaging technology, coupled with the availability of 3-D datasets such as the Visible Human, provide a unique opportunity for developing information systems in anatomy that can deliver relevant knowledge directly to the clinician, researcher or educator. A software framework is described for developing such a system within a distributed architecture that includes spatial and symbolic anatomy information resources, Web and custom servers, and authoring and end-user client programs. The authoring tools have been used to create 3-D atlases of the brain, knee and thorax that are used both locally and throughout the world. For the one and a half year period from June 1995-January 1997, the on-line atlases were accessed by over 33,000 sites from 94 countries, with an average of over 4000 "hits" per day, and 25,000 hits per day during peak exam periods. The atlases have been linked to by over 500 sites, and have received at least six unsolicited awards by outside rating institutions. The flexibility of the software framework has allowed the information system to evolve with advances in technology and representation methods. Possible new features include knowledge-based image retrieval and tutoring, dynamic generation of 3-D scenes, and eventually, real-time virtual reality navigation through the body. Such features, when coupled with other on-line biomedical information resources, should lead to interesting new ways for managing and accessing structural information in medicine. PMID:9466836

    Mavrodi, Alexandra; Paraskevas, George


    Previously, anatomists considered paranasal sinuses as a mysterious region of the human skull. Historically, paranasal sinuses were first identified by ancient Egyptians and later, by Greek physicians. After a long period of no remarkable improvement in the understanding of anatomy during the Middle Ages, anatomists of the Renaissance period-Leonardo da Vinci and Vesalius-made their own contribution. Nathaniel Highmore's name is also associated with the anatomy of paranasal sinuses as he was ...

  12. 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.

  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. Clin.

  14. 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. PMID:21804185

  12. Anatomy comic strips. (United States)

    Park, Jin Seo; Kim, Dae Hyun; Chung, Min Suk


    Comics are powerful visual messages that convey immediate visceral meaning in ways that conventional texts often cannot. This article's authors created comic strips to teach anatomy more interestingly and effectively. Four-frame comic strips were conceptualized from a set of anatomy-related humorous stories gathered from the authors' collective imagination. The comics were drawn on paper and then recreated with digital graphics software. More than 500 comic strips have been drawn and labeled in Korean language, and some of them have been translated into English. All comic strips can be viewed on the Department of Anatomy homepage at the Ajou University School of Medicine, Suwon, Republic of Korea. The comic strips were written and drawn by experienced anatomists, and responses from viewers have generally been favorable. These anatomy comic strips, designed to help students learn the complexities of anatomy in a straightforward and humorous way, are expected to be improved further by the authors and other interested anatomists.

    Knowledge of normal and anomalous formation of brachial plexus and its branches is of utmost importance to anatomists, clinicians, anesthesiologists and surgeons. Possibility of variations in the origin, course and distribution of branches of brachial plexus must be kept in mind during anesthetizing the brachial plexus, mastectomy and plastic surgery procedures. In the current case, the medial pectoral nerve arose directly from the middle trunk of the brachial plexus and the lateral pectoral ...

  18. Retrogressive development: transcendental anatomy and teratology in nineteenth-century Britain


    Bates, A W


    In 1855 the leading British transcendental anatomist Robert Knox proposed a theory of retrogressive development according to which the human embryo could give rise to ancestral types or races and the animal embryo to other species within the same family. Unlike monsters attributed to the older theory of arrested development, new forms produced by retrogression were neither imperfect nor equivalent to a stage in the embryo’s development. Instead, Knox postulated that embryos contained all poss...

  19. About muscle insertions in man (Proposal for a new nomenclature of striated muscle)




    SUMMARY Some plastic surgeons are limited in their technical knowledge on the mimetic muscle and conversely appear to vindicate a distinct priority in the problem of surgical rejuvenation, or, in general, in the effects of ageing, always involving the mimetic muscles included in the skin. Anatomists have worked better in research on mimetic muscles that we would like to indicate as not inserted, free to move in a different way from that of inserted or semi-inserted. Otolaryngologists and maxi...

    Anatomists use human bodies for research, teaching and advanced medical training. Despite a long tradition and the more recent legal regulation of 'body donation', this practise is nevertheless burdened with legal and ethical uncertainties. Therefore, modern-day anatomy still needs a well-founded legitimation of cadaver use. The educational research presented here demonstrates that, on methodological grounds, it remains difficult to produce a 'final' judgement on the effectiveness of anato...

  3. 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. PMID:26965250

  6. A core syllabus for the teaching of neuroanatomy to medical students. (United States)

    Moxham, Bernard; McHanwell, Stephen; Plaisant, Odile; Pais, Diogo


    There is increasingly a call for clinical relevance in the teaching of biomedical sciences within all health care courses. However, this presupposes that there is a clear understanding of what can be considered core material within the curricula. To date, the anatomical sciences have been relatively poorly served by the development of core syllabuses, particularly for specialized core syllabuses such as neuroanatomy. One of the aims of the International Federation of Associations of Anatomists (IFAA) and of the European Federation for Experimental Morphology (EFEM) is to formulate, on an international scale, core syllabuses for all branches of the anatomical sciences using Delphi Panels consisting of anatomists, scientists, and clinicians to initially evaluate syllabus content. In this article, the findings of a Delphi Panel for neuroanatomy are provided. These findings will subsequently be published on the IFAA website to enable anatomical (and other cognate learned) societies and individual anatomists, clinicians, and students to freely comment upon, and elaborate and amend, the syllabuses. The aim is to set internationally recognized standards and thus to provide guidelines concerning neuroanatomical knowledge when engaged in course development. PMID:26119890

  7. How the distinctive cultures of osteopathic and allopathic medical schools affect the careers, perceptions, and institutional efforts of their anatomy faculties: A qualitative case study of two schools. (United States)

    Brokaw, James J; Byram, Jessica N; Traser, Courtney J; Arbor, Tafline C


    Anatomy faculties are integral to basic science instruction in medical schools, particularly given the preponderance of anatomic instruction in the preclinical curriculum. Recent years have witnessed major curricular restructuring and other emerging national trends that pose significant challenges to anatomists. An examination of anatomy faculty perceptions at two philosophically distinct medical schools within this shifting climate provides an indicator of how different institutional characteristics may impact anatomy instruction and other faculty responsibilities. Semistructured interviews of anatomy faculty from a large, well-established allopathic medical school (Indiana University School of Medicine) and a small, new osteopathic medical school (Marian University College of Osteopathic Medicine) were explored using qualitative thematic analysis. Four overarching themes were identified: (1) Institutional philosophies, such as affiliation with osteopathic versus allopathic medicine, have minimal impact on how the anatomical sciences are taught. (2) Differences in anatomy faculty experiences at these two institutions are largely driven by the institution's size and history. There is a disparity between institutions in the relative importance of teaching and research, but an ability to do research is important for both faculties. (3) Anatomy instruction and research agendas are driven by personal philosophies and interests rather than institutional philosophy. (4) Autonomy is highly valued by anatomists at both institutions. All the participants share a devotion to educating future physicians. In fact, this study identified more similarities than differences in these two faculties. Finally, we argue that shared educational resources and research collaborations can improve anatomy education and faculty development at both institutions.

  10. Absence of musculocutaneous nerve in the left axilla

    Directory of Open Access Journals (Sweden)

    Virupaxi RD


    Full Text Available Variations of the arrangement and distribution of the lateral cord and its branches in the infraclavicular part of the brachial plexus are common in one or both axillae. These variations are important to the surgeons, neurologists, anesthetists and anatomists during surgery and dissection in the region of axilla. The present case report describes the absence of musculocutaneous nerve in the infraclavicular part of left brachial plexus, observed during routine dissection of a 40-year-old male Indian cadaver. On the right side usual origin and course of musculocutaneous nerve was seen. The clinical importances of these variations are discussed.

  11. Study of supracondylar process of humerus

    Directory of Open Access Journals (Sweden)

    Ravi Vandana


    Full Text Available The supra condylar process is occasional beak like projection from anteromedial surface of distal 1/3 rd of humerus. It appears to be phylogenetic remnant of complete osseous bridge found in reptiles, marsupials, cats, lemurs and new world monkeys. Among 133 dried humeri studied only one right humerus showed SCP (incidence 0.75% whose dimensions were recorded and photographed. SCP is usually clinically silent but can be the cause for median or ulnar nerve and brachial artery compression syndrome especially when associated with Struthers ligament. Therefore the knowledge of presence of SCP is important for clinicians and radiologists along with anatomists and anthropologists.

  12. The methodology of natural sciences in antiquity and the second book of Galen’s De placitis Hippocratis et Platonis

    Directory of Open Access Journals (Sweden)

    Koptseva, Natalia


    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.

  13. History of the current understanding and management of tethered spinal cord. (United States)

    Safavi-Abbasi, Sam; Mapstone, Timothy B; Archer, Jacob B; Wilson, Christopher; Theodore, Nicholas; Spetzler, Robert F; Preul, Mark C


    An understanding of the underlying pathophysiology of tethered cord syndrome (TCS) and modern management strategies have only developed within the past few decades. Current understanding of this entity first began with the understanding and management of spina bifida; this later led to the gradual recognition of spina bifida occulta and the symptoms associated with tethering of the filum terminale. In the 17th century, Dutch anatomists provided the first descriptions and initiated surgical management efforts for spina bifida. In the 19th century, the term "spina bifida occulta" was coined and various presentations of spinal dysraphism were appreciated. The association of urinary, cutaneous, and skeletal abnormalities with spinal dysraphism was recognized in the 20th century. Early in the 20th century, some physicians began to suspect that traction on the conus medullaris caused myelodysplasia-related symptoms and that prophylactic surgical management could prevent the occurrence of clinical manifestations. It was not, however, until later in the 20th century that the term "tethered spinal cord" and the modern management of TCS were introduced. This gradual advancement in understanding at a time before the development of modern imaging modalities illustrates how, over the centuries, anatomists, pathologists, neurologists, and surgeons used clinical examination, a high level of suspicion, and interest in the subtle and overt clinical appearances of spinal dysraphism and TCS to advance understanding of pathophysiology, clinical appearance, and treatment of this entity. With the availability of modern imaging, spinal dysraphism can now be diagnosed and treated as early as the intrauterine stage. PMID:26967990

  14. [Andreas Vesalius: his rich imagination and colorful detail account in his book: 'Research of the anatomical observations of Gabriel Falloppius']. (United States)

    Gilias, Guy


    In a long letter, Andreas Vesalius reacts to the comments made by Gabriel Falloppius to his work 'De Humani Corporis Fabrica'. In this letter, he proves Falloppius wrong in a number of assertions and corrects him on more than one occasion. In doing so, Vesalius as a renaissance humanist uses a classic Latin language with long elegant sentences in the style of the old Roman orator Cicero. Remarkably interesting is the fact that this whole argumentation is spiced with comparisons and examples from daily life. To make it clear to the reader what a certain part of the skeleton looks like, he compares this part with an object everybody knows. All parts of the human body are depicted in such an almost graphic way that even an interested reader without any medical or anatomic education can picture them. And Vesalius is very creative in doing so, an artist as it were with a very rich imagination. Moreover, it's remarkable how the famous anatomist manages to put himself on the level of any ordinary person, using comparative images on that level. This last work of Vesalius, which he himself considers to be a supplement to his De Humani Corporis Fabrica, deserves special attention, not only because it illustrates the scientific evolution of the anatomist Vesalius, but also because it offers an insight in the psychology of that fascinating scientist Andreas Vesalius.

  15. Executions and scientific anatomy. (United States)

    Dolezal, Antonín; Jelen, Karel; Stajnrtova, Olga


    The very word "anatomy" tells us about this branch's connection with dissection. Studies of anatomy have taken place for approximately 2.300 years already. Anatomy's birthplace lies in Greece and Egypt. Knowledge in this specific field of science was necessary during surgical procedures in ophthalmology and obstetrics. Embalming took place without public disapproval just like autopsies and manipulation with relics. Thus, anatomical dissection became part of later forensic sciences. Anatomical studies on humans themselves, which needed to be compared with the knowledge gained through studying procedures performed on animals, elicited public disapprobation and prohibition. When faced with a shortage of cadavers, anatomists resorted to obtaining bodies of the executed and suicide victims - since torture, public display of the mutilated body, (including anatomical autopsy), were perceived as an intensification of the death penalty. Decapitation and hanging were the main execution methods meted out for death sentences. Anatomists preferred intact bodies for dissection; hence, convicts could thus avoid torture. This paper lists examples of how this process was resolved. It concerns the manners of killing, vivisection on people in the antiquity and middle-ages, experiments before the execution and after, vivifying from seeming death, experiments with galvanizing electricity on fresh cadavers, evaluating of sensibility after guillotine execution, and making perfect anatomical preparations and publications during Nazism from fresh bodies of the executed.

  16. A study of cephalic index and facial index in Visakhapatnam, Andhra Pradesh, India

    Directory of Open Access Journals (Sweden)

    K. Lakshmi Kumari


    Full Text Available Background: The description of the human body has been a major concern since ancient times. The use of medical terminology enhances reliability of comparison made between studies from different areas thereby contributing higher level of scientific evidence. Cephalic index is an important parameter in forensic medicine, anthropology and genetics to know the sex and racial differences between individuals. Facial index is useful index for forensic scientists, plastic surgeons and anatomist. The parameters are useful for plastic surgeons during treatment of congenital and traumatic deformities, identification of individuals in medicolegal cases by forensic scientists and identifying craniofacial deformities of genetic syndromes by geneticist. Methods: 170 males and 110 female adults from Visakhapatnam, Andhra Pradesh, India region are included in this study. Anthropometric points for cephalic index were measured by using spreading calipers. Facial index measurements were taken by measuring tape. All measurements were taken in subjects sitting in relaxed condition and subjects head is in anatomical position. Cranial index and facial index were calculated as per the formula. Results: Maximum number of males with mean cephalic index values of 80.21 were observed as mesocephalic and female with mean value of 79.25 observed as brachycephalic. Regarding facial index males were leptoprosopic and females were mesoprosopic. Conclusion: Cephalic index and facial index were terms used by anthropologists, anatomists, plastic surgeons and forensic scientists to identify individual's race and sex for treatment of craniofacial deformities.

    Zemmoura, I; Vons, J; Velut, S; Destrieux, C


    The description of an anatomical specimen may look straightforward, but it appears that it depends in fact on several intermingled factors: technical methods for conservation, dissection and vascular injection and the anatomist skills are of course important. This is especially true when the studied organ, as for instance the brain, is subject to rapid putrefaction after death without any preservation technique. Nevertheless the possibility to reject, or at least criticize, the dominant paradigm is probably as important as these technical considerations: important changes occurred in brain representation between the early Middle Ages and the Early Modern Times, without major improvements of cadaveric preservation or dissection methods; Vesalius rejected the existence of the rete mirabile in human not only because he was a talented anatomist but also because he accepted and had the courage to fight the dominant tradition inherited from Galen. Such difficulties in the scientific approach obviously remain vivid, and should not be forgotten despite the development of modern tools for studying brain morphology and function. PMID:26354184

  18. Anatomy's use of unclaimed bodies: reasons against continued dependence on an ethically dubious practice. (United States)

    Jones, D Gareth; Whitaker, Maja I


    The use of unclaimed bodies has been one of the distinguishing features of the anatomy profession since the passing of nineteenth century legislation aimed at solving the problem of grave robbing. Only in more recent years has the use of bequeathed bodies supplanted dependence upon unclaimed bodies in many (but not all) countries. We argue that this dependence has opened the profession to a range of questionable ethical practices. Starting with contraventions of the early Anatomy Acts, we trace the manner in which the legitimacy of using unclaimed bodies has exposed vulnerable groups to dissection without their consent. These groups have included the impoverished, the mentally ill, African Americans, slaves, and stigmatized groups during the Nazi era. Unfortunately, ethical constraints have not been imposed on the use of unclaimed bodies. The major public plastination exhibitions of recent years invite us to revisit these issues, even though some like Body Worlds claim to use bequeathed bodies. The widespread use of unclaimed bodies in institutional settings has lent to these public exhibitions a modicum of legitimacy that is needed even when donated bodies are employed. This is because the notion of donation has changed as demonstrated by consideration of the principles of beneficence and non-maleficence. We conclude that anatomists should cease using unclaimed bodies. Difficult as this will be in some cultures, the challenge for anatomists is to establish relationships of trust with their local communities and show how body donation can assist both the community and the profession.

  19. Review of the Historical Evolution of Anatomical Terms

    Directory of Open Access Journals (Sweden)

    Algieri, Rubén D.


    Full Text Available Most of the medical terms of Greek origin are traditionally attributed to Hippocrates (460-370 BC. Claudius Galen of Pergamum (130-200 BC developed a classification of bones and joints and described different brain areas. His teachings have remained unchanged for over a thousand years. Andreas Vesalius of Brussels (1514-1564, through the systematic study of human body structure, changed many concepts. He published his work in his production "De humani corporis fabrica libri septem", where a special attention is evident to the discovery and description of new anatomical facts. From here there is a revolution in the morphological sciences, where the same anatomical structure passed to receive different names. In the nineteenth century, the different anatomists in the world decide to meet in order to unify criteria regarding the anatomical structures and determine a only one universal language in the anatomical sciences. In 1895, in Basel (Switzerland it’s approved a list of 5.573 terms, called Basle Nomina Anatomica (BNA and was written in Latin. Eponyms were deleted. In 1903, he founded the International Federation of Associations of anatomists (IFAA. In 1935, in Jena (Germany, approving the Jena Nomina Anatomica (JNA. In 1950, in Oxford, formed the Committee of the International Anatomical Nomenclature (IANC. In 1955, in Paris (France it is agreed to adopt a Latin nomenclature based on the BNA, the Paris Nomina Anatomica (PNA. In 1980, for the first time in Latin America, takes place on the 11th International Congress of Anatomists, Mexico. In 1989, the International Committee of Anatomical Nomenclature, published the sixth edition of the Nomina Anatomica, without review by the IFAA. The same year, the latter established a Federative International Committee of Anatomical Terminology (FICAT. In 1998, he published a new list FICAT: International Anatomical Terminology (TAI, with the structures named in Latin language and their equivalence in

    Raney, Marcella A


    This study examined the impact of iPad integration on performance in an undergraduate gross anatomy course. Two out of six course sections were assigned to one of the following conditions: control (no iPad, n = 61); limited access (laboratory iPads, n = 58); and unlimited access (personal iPads, n = 47). Student knowledge was assessed over time during the semester with two practical examinations in laboratory and four multiple choice/essay examinations in lecture. The same PowerPoint presentations and examinations were utilized for all conditions. Mixed ANOVA analysis identified an interaction effect between time and condition for both laboratory (F2,153  = 16.12; P learning curve, tablet devices and relevant applications can be useful tools in human anatomy courses.

  1. 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.

  2. Imaging in the context of replacement heart valve development: use of the Visible Heart(®) methodologies. (United States)

    Bateman, Michael G; Iaizzo, Paul A


    In recent years huge strides have been made in the fields of interventional cardiology and cardiac surgery which now allow physicians and surgeons to repair or replace cardiac valves with greater success in a larger demographic of patients. Pivotal to these advances has been significant improvements in cardiac imaging and improved fundamental understanding of valvular anatomies and morphologies. We describe here a novel series of techniques utilized within the Visible Heart(®) laboratory by engineers, scientists, and/or anatomists to visualize and analyze the form and function of the four cardiac valves and to assess potential repair or replacement therapies. The study of reanimated large mammalian hearts (including human hearts) using various imaging modalities, as well as specially prepared anatomical specimens, has enhanced the design, development, and testing of novel cardiac therapies.

  3. A method for ultrasonographic visualization and injection of the superior laryngeal nerve: volunteer study and cadaver simulation. (United States)

    Kaur, Balvindar; Tang, Raymond; Sawka, Andrew; Krebs, Claudia; Vaghadia, Himat


    Superior laryngeal nerve block is a valuable technique for provision of upper airway anesthesia. In bilateral scans of 20 volunteers, we developed a technique for ultrasonographic visualization of the superior laryngeal nerve and key anatomical structures using a hockey stick-shaped 8 to 15 MHz transducer (HST15 to 8/20 linear probe, Ultrasonix, Richmond, BC, Canada). Subsequently, we simulated superior laryngeal nerve scanning and injection in bilateral injections in 2 cadavers. Ultrasound-guided in-plane advancement of a needle toward the superior laryngeal nerve and injection of 1 mL of green dye was achieved in all 4 attempts and confirmed by a postprocedural dissection performed by an anatomist. We conclude that ultrasound-guided superior laryngeal nerve block in humans may be feasible. PMID:22822197

  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. PMID:21879195

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

    International Nuclear Information System (INIS)

    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

  6. Retrogressive development: transcendental anatomy and teratology in nineteenth-century Britain. (United States)

    Bates, Alan W H


    In 1855 the leading British transcendental anatomist Robert Knox proposed a theory of retrogressive development according to which the human embryo could give rise to ancestral types or races and the animal embryo to other species within the same family. Unlike monsters attributed to the older theory of arrested development, new forms produced by retrogression were neither imperfect nor equivalent to a stage in the embryo's development. Instead, Knox postulated that embryos contained all possible specific forms in potentia. Retrogressive development could account for examples of atavism or racial throwbacks, and formed part of Knox's theory of rapid (saltatory) species change. Knox's evolutionary theorizing was soon eclipsed by the better presented and more socially acceptable Darwinian gradualism, but the concept of retrogressive development remained influential in anthropology and the social sciences, and Knox's work can be seen as the scientific basis for theories of physical, mental and cultural degeneracy.

  7. Andreas Vesalius as a renaissance innovative neuroanatomist: his 5th centenary of birth

    Directory of Open Access Journals (Sweden)

    Marleide da Mota Gomes


    Full Text Available 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.

  8. Three-Dimensional Display Technologies for Anatomical Education: A Literature Review (United States)

    Hackett, Matthew; Proctor, Michael


    Anatomy is a foundational component of biological sciences and medical education and is important for a variety of clinical tasks. To augment current curriculum and improve students' spatial knowledge of anatomy, many educators, anatomists, and researchers use three-dimensional (3D) visualization technologies. This article reviews 3D display technologies and their associated assessments for anatomical education. In the first segment, the review covers the general function of displays employing 3D techniques. The second segment of the review highlights the use and assessment of 3D technology in anatomical education, focusing on factors such as knowledge gains, student perceptions, and cognitive load. The review found 32 articles on the use of 3D displays in anatomical education and another 38 articles on the assessment of 3D displays. The review shows that the majority (74 %) of studies indicate that the use of 3D is beneficial for many tasks in anatomical education, and that student perceptions are positive toward the technology.

  11. 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. PMID:24447741

  12. Rare variation of flexor digitorum longus muscle of leg – a case report

    Directory of Open Access Journals (Sweden)



    Full Text Available Flexor digitorum longus is one of the muscles of posterior compartment of leg. This paper primarily focuses on the variation of flexor digitorum longus muscle of leg. Sixty inferior extremities were dissected. A small muscle taking origin from the tendon of flexor digitorum longus was observed. Some of the fibers were originating from the fascia covering the flexor digitorum longus and tibialis posterior. Its tendon merged with the tendon of flexor digitorum longus going to second digit in sole of foot and quadratus plantae. Nerve supply of this muscle was from a small branch of tibial nerve from its undersurface. Supernumerary muscles in the ankle joint or nearby region can be a factor of compression in tarsal tunnel syndrome. MRI is the modality of choice in diagnosing accessory muscles. Functional and clinical significance is important not only for the anatomist and clinicians but also for the pathologists and sports people.

  13. The fourfold Democritus on the stage of early modern science. (United States)

    Lüthy, C


    The renewed success of ancient atomism in the seventeenth century has baffled historians not only because of the lack of empirical evidence in its favor but also because of the exotic heterogeneity of the models that were proposed under its name. This essay argues that one of the more intriguing reasons for the motley appearance of early modern atomism is that Democritus, with whose name this doctrine was most commonly associated, was a figure of similar incoherence. There existed in fact no fewer than four quite different Democriti of Abdera and as many literary traditions: the atomist, the "laughing philosopher," the moralizing anatomist, and the alchemist. Around the year 1600 the doctrines of these literary figures, three of whom had no tangible connection with atomism, began to merge into further hybrid personae, some of whom possessed notable scientific potential. This essay offers the story of how these Democriti contributed to the rise of incompatible "atomisms." PMID:11143784

    Full Text Available Neural variations of the brachium constitute important anatomical and clinical entity.Abnormal variations of median nerve, musculocutaneous nerve and their communicating branches have been reported very frequently by the anatomists in the past. The nerves of the extremities are particularly vulnerable to injury because of their long course and superficial distribution. Present report describes a case of a single abnormal communication between median and musculocutaneous nerve encountered in a 55 year old Indian male cadaver during routine undergraduate dissection. Knowledge of such anatomical variations is important while planning surgery in the region of axilla or arm as these nerves are more liable to be injured during surgical procedures as well as may result in unusual entrapment neuropathies. Clinical significance of such type of variation in the light of its developmental origin has been discussed.

  15. 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.

  16. [The alteration of Japanese anatomical terminology in the early Showa period and the Japanese language reform campaign]. (United States)

    Sawai, Tadashi; Sakai, Tatsuo


    In the second decade of the Showa period, great changes were made in the Japanese anatomical terms. It has been proposed that the presentation of JNA (Jenaer nomina anatomica) was one of the factors leading to the change. The Japanese language reform campaign, however, played an important role. The party kokugoaigo doumei and its successor kokugo kyokai required concise and unified technical terms. The anatomical nomenclature committee of the Japanese Association of Anatomists worked to satisfy this requirement. The committee consulted with nomenclature committees of other medical associations and took account of their opinions. The anatomical nomenclature committee abandoned the literal translation from Latin to Japanese and shaped a succinct Japanese terminology. Modern Japanese anatomical terms are based on this terminology. PMID:20614732

  19. Retinohypothalamic pathway: a breach in the law of Newton-Müller-Gudden? (United States)

    Magnin, M; Cooper, H M; Mick, G


    Theories of binocular vision originally imagined by Newton provided the foundation for subsequent investigations of the visual system by early anatomists and physiologists. These studies led to the widely accepted concept that degree of optic fiber decussation in the chiasm is inversely related to frontal orientation of the optical axes of the eyes (law of Newton-Müller-Gudden). A survey of 23 species from 11 mammalian orders demonstrates that, in contrast to other visual pathways, the retinohypothalamic projection does not obey this general principle. In further contradiction, an unexpected finding in primates is the predominance of ipsilateral, rather than contralateral, retinal input to the suprachiasmatic nucleus. This unusual organization underlines the functional and evolutionary specificities of this 'non-image forming' visual pathway. PMID:2743136

    Krstonosic B


    Full Text Available Superficial brachial artery is one of the major variations of the arterial pattern in the upper limb. During routine anatomical dissection in our department, we observed a case of unilateral double brachial artery in a formalin-fixed female cadaver.Left axillary artery entered into the anterior region of the arm, where it branched into two brachial arteries – the superficial brachial artery (SBA, which was longer, tortuous and with a smaller caliber, and the brachial artery (BA, which was placed deep and medially. In the cubital fossa, covered with an aponeurosis of the biceps brachii muscle, both brachial arteries were connected with an anastomotic vessel. Under this anastomotic branch, in the forearm, SBA continued as the radial artery, whereas BA continued as the ulnar artery.Variations of the arterial pattern in the upper limb are undoubtedly of interest to the anatomists as well as to the clinicians.

    Sheikh, Ahmad Hassan; Barry, Denis S; Gutierrez, Humberto; Cryan, John F; O'Keeffe, Gerard W


    Reduced contact hours and access to cadaveric/prosection-based teaching in medical education has led to many doctors reporting inadequate anatomical knowledge of junior doctors. This trend poses significant risk, but perhaps most of all in surgery. Here the opinions of surgeons regarding current and future teaching practices in anatomy were surveyed. Eighty surgeons were invited to complete a questionnaire, 48 of which were returned for a 60% response rate. Respondents were asked to select the method they viewed as the best method of teaching anatomy. Sixty-five percent of respondents selected "cadaver/prosection demonstration" (P integrated into anatomical education. These findings support the continued use of cadaveric/prosection-based teaching, and will help inform the integration of radiology in the design and implementation of anatomy teaching in medical education.

  3. The science prior to the crime--August Hirt's career before 1941. (United States)

    Uhlmann, Angelika; Winkelmann, Andreas


    August Hirt (1898-1945) has achieved macabre renown for atrocities perpetrated during his years as professor of anatomy at the Reichsuniversität Straßburg 1941-1945. Little, however, is known about his preceding scientific career. To fill this gap and to scrutinise whether he really was a mediocre scientist during his early years, as some have purported, we perused relevant historical archives and the available literature. In 1921, after medical school, Hirt started to research and teach at the Institute of Anatomy in Heidelberg, forging a steady career until becoming interim chair in 1935. He then became director of anatomical institutes in Greifswald 1936 and Frankfurt 1938 before going to Straßburg in 1941. Hirt seems to have been well-established in the community of anatomists. Some of his career advancements after 1933 were nevertheless facilitated by Nazi support. His main scientific fields were the autonomic nervous system, in which he produced a relevant contribution to anatomical knowledge, and fluorescence microscopy. His development of a special "luminescence microscope", in cooperation with pharmacologist Ellinger, was an important advancement in the history of microscopic technique. His early research was funded by national and international sponsoring bodies and was neither unethical nor racist. As Hirt did not publish anything after 1940, those who only knew his publications might think of him as a "good" scientist. To simply dismiss Hirt as a "pseudoscientist" would avoid the question-still difficult to answer-of how he could develop from an accepted, successful anatomist to a criminal "in the name of science".

  4. Frederik Ruysch's Fascination With Urolithiasis (United States)

    Moran, Michael E.; Ruzhansky, Katherine


    Frederik Ruysch was born on March 23, 1638, in The Hague, and studied at the University of Leiden, where he graduated in 1664. He married a daughter of a famous architect and became a praelector of the Amsterdam surgeon's guild in 1665. In 1666, his rise continued, as he became elected as the Professor of the Anthenaeum Illustre. In 1668, Ruysch became the chief instructor to the midwives and by 1679 was the forensics advisor to Amsterdam's courts. His anatomical knowledge was second to none, and he gained worldwide notoriety for his discovery of the valves in lymphatics and the vomeronasal organ. Ruysch was keenly interested in dissection and anatomy, and developed his own methods for preservation of specimens. His secret was called liquor balsamicum. Over 300 years ago, Ruysch developed all of his talents to the point of creating a menagerie, of sorts, out of his specimens. The popularity of his rather morbid exhibits attracted such dignitaries as Peter The Great in 1697. Ruysch had several children from his marriage, and his daughter Rachel helped him illustrate many of his collections. Frederik Ruysch became an intriguing historical figure, worthy of some attention at kidney stone meetings, precisely because he chose these concretions to serve as one of the "finishing elements" in several of his collections. The purpose of this presentation is to present to a knowledgeable stone group, the artistic license of one of the first entrepreneurial surgeons and anatomists of the 17th century. Ruysch was a skilled surgeon, obstetrician, and anatomist, keenly interested in the science of anatomy, especially infant and fetal anatomy. In addition, he exhibited his fine collection of urinary stones in a rather unique way, in his "anatomical pieces."

    Full Text Available Anatomy and dissection have long been considered a cornerstone in medical education, irrespective of nation, racial background or medical school. By learning gross anatomy, medical students get a first “impression” about the structure of human body which is the basis for understanding pathologic and clinical problems. Anatomy teaching methodology has been revolutionized in the 2Ist century, due to time constraints, less availability of cadavers, stress on computer aided learning, scarcity of qualified teachers, changes in the demands of medical profession and neglect of vertical integration of anatomy teaching. Until recently, dissection and didactic lectures were its sole pedagogy, worldwide. But over the last few decades, traditional anatomy teaching based on topographical structural anatomy taught in lectures and gross dissection classes has been replaced by a vivid range of study modules like problem based learning(PBL and computer assisted learning(CAL,and curricula integration. Though the anatomy curriculum is undergoing international reformation but it lacks uniformity among institutions. The available modern international literature, describing various methodologies for teaching/learning anatomy conclude that Anatomists are constantly debating over the following questions-How much to teach, when to teach and how to teach gross anatomy. We endeavor to answer these questions and contribute to the debate on the ideal methodology for teaching /learning anatomy. Alternative strategies and resources are also discussed so that we can re establish more effective teaching /learning tools while maintaining the beneficial values of orthodox dissection .If we are not concentrating on optimum anatomy education, it will inevitably lead to incompetent anatomists and healthcare professionals, leaving patients to face unwanted consequences of medical error.

  6. Gruber, Gradenigo, Dorello, and Vail: key personalities in the historical evolution and modern-day understanding of Dorello's canal. (United States)

    Reddy, Renuka K; Reddy, Rohit K; Jyung, Robert W; Eloy, Jean Anderson; Liu, James K


    A century ago an ambitious young anatomist in Rome, Primo Dorello, who sought to understand the cause of abducent nerve palsy that often occurred in patients with severe middle ear infections, conducted intricate studies on the intracranial course of the nerve. In his findings, he identified that the abducent nerve passes through a narrow sinus near the apex of the petrous bone, which formed an osteofibrous canal. Dorello suggested that in this enclosed region the abducent nerve may be particularly vulnerable to compression due to the vascular edema accompanying the infection. Although his work was widely appreciated, it was not well received by all. Interestingly, Giuseppe Gradenigo, one of the most prominent Italian otologists of the early 20th century, who was known for his work on a triad of symptoms (Gradenigo's syndrome) that accompanies petrous apicitis, a result of severe middle ear infections, was obstinate in his criticism of Dorello's findings. Thus a scientific duel began, with a series of correspondence between these two academics-one who was relatively new to the otological community (Dorello) and one who was well reputed in that community (Gradenigo). The disagreement ultimately ebbed in 1909, when Dorello published a report in response to Gradenigo's criticisms and convinced Gradenigo to change his views. Today Dorello's canal is widely recognized as a key landmark in skull base surgery of the petroclival region and holds clinical significance due to its relation to the abducent nerve and surrounding vascular structures. Yet, although academics such as Dorello and Gradenigo are recognized for their work on the canal, it is important not to forget the others throughout history who have contributed to the modern-day understanding of this anatomical structure. In fact, although the level of anatomical detail found in Dorello's work was previously unmatched, the first description of the canal was made by the experienced Austrian anatomist Wenzel Leopold

  7. Life and works of Jovan Andrejević Joles

    Gudović Radmila


    Full Text Available The first Serbian anatomist Jovan Andrejević Joles was born in Novi Sad on October 6, 1833 to a priest father. The primary school and the first four grades of the grammar school he finished in Novi Sad, and the seventh and the eighth grades in Timisoara. After finishing grammar school, Andrejević moved to Pest where he started medical studies in 1853. He continued the studies in Prague and Vienna where he received the diploma of a doctor of medicine. During the studies of medicine, this remarkably educated and talented man demonstrated great interest in science. In his research he came to new findings he published through the report of the Vienna Academy of Sciences in the paper titled 'On the Fine Structure of the Liver' (Ueber den feineren Bau der Leber, making his mentor, professor Ernest von Brücke, proud. Apart from the scientific work, young Andrejević also translated literature from German and English. His interests also covered photography, art and aesthetics. He actively participated in the work of the United Serbian Youth, which brought him many problems with the ruling regime of the time. At a very early age, Andrejević fell down with tuberculosis and had to stop his scientific work and move back to Novi Sad in 1861 where he began working as a physician. Apart from the medical practice, Andrejević was still in the center of scientific, political, and cultural events. He continued regular correspondence with professor von Brücke who informed him on the success of his scientific results. Apart from a number of texts and critical writings, together with Jovan Đorđević, Andrejević worked hard on the foundation of the Serbian National Theater in Novi Sad. During 1863, his illness aggravated and he died of tuberculosis on July 21, 1864. The memory of the first Serbian anatomist is kept by the Department of Anatomy of the Faculty of Medicine in Novi Sad where the documentation on his life and works is stored. The ground floor hall

  8. [Wenzel Leopold Gruber (1814-1890)]. (United States)

    Naňka, Ondřej


    Gruber was born in Krukanice, a small village near to Pilsen on September 24, 1814. He started his medical studies in Prague at 1834. He became doctor of surgery in 1842, and in 1844 was conferred doctor of medicine. He was prosector of normal anatomy at the University of Prague in 1842-1847. Although qualified, he was unable to achieve a professorship in his native country. Therefore, in 1846, on the initiative of Pirogov, he was invited to become the first prosector for normal, practical, and pathological anatomy at the Medical Academy in St. Petersburg. From 1855, Gruber was entrusted the directorship of practical anatomy, remaining at that position for some 30 years. He died on September 30 1890 of stroke in Vienna. Gruber played an active role in the establishment of the anatomical-physiological institute in Petersburg and founded here a museum. As one of the most experienced and active anatomists, Gruber published, over a period of 41 years, almost 500 scientific works. PMID:25994912

  9. 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. PMID:24041279

  10. Curricular response to increase recall and transfer of anatomical knowledge into the obstetrics/gynecology clerkship. (United States)

    Jurjus, Rosalyn A; Brown, Kirsten; Goldman, Ellen; Galoosian, Artin; Butera, Gisela; Krapf, Jill M


    Deficits in retention of anatomy knowledge from the preclinical years to clinical application on the wards have been well documented in the medical education literature. We developed and evaluated a web and laboratory-based curriculum to address deficits in anatomy knowledge retention and to increase anatomy knowledge recall through repetition and application of clinical concepts during the obstetrics and gynecology (Ob/Gyn) core clinical clerkship. Using principles of adult learning and instructional design, a curriculum was designed consisting of (1) interactive, case-based e-modules reviewing clinically relevant anatomical topics and (2) a hands-on laboratory session reinforcing the content of the e-modules, with the practice of clinical techniques using anatomical cadaveric dissections. The curriculum's effectiveness was evaluated by using multiple choice testing and comparing baseline and final test scores. For questions testing content directly covered in this curriculum, mean final scores increased by 14.3% (P improvement, P = 0.002). A curriculum with web-based preparatory material and a hands-on gross anatomy laboratory session effectively addresses deficits in anatomy retention and improves anatomical knowledge recall for medical students on a clinical clerkship. In the future, the authors plan to conduct a multicenter study to further evaluate the ability of this curriculum to improve clinically relevant anatomical knowledge.

  11. Dryander of Marburg and the first textbook of neuroanatomy. (United States)

    Hanigan, W C; Ragen, W; Foster, R


    Born in Wetter, Germany, in 1500, Johannes Eichmann (Dryander) studied medicine and anatomy at the University of Paris from 1528 to 1534. In 1535, he was appointed professor of medicine at the University of Marburg. During the next year he held two public dissections, and in 1536 he was the author of the first text illustrating a Galenic dissection of the human brain. An expanded edition of this early book, the Anatomiae pars prior, was published in 1537. These texts represented an important transition from the dogma of medieval scholasticism to the precise observations of Vesalius. The books depicted the brain in eight figures, with four additional plates describing the skull, skull base, and cranial sutures. Detailed illustrations of the dura mater, cerebral cortex, and posterior fossa structures with clear, but inaccurate, relationship to the cranial nerves demonstrated Dryander's reliance on his own dissections. In 1542, he published a translated edition of Mundinus' anatomy. As was common at that time, the text plagiarized a portion of Vesalius' Tabulae sex, which resulted in the famous anatomist's anger. Despite this, Dryander continued to write on medical subjects as well as mathematics and astrology until his death in 1560. Because he was a progenitor of rational scientific thought, his earlier books represented an important advance in the progression to modern anatomic description and illustration. PMID:2181335

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

    Ghosh, Sanjib Kumar


    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.

  13. Contributions of Johann jacob Huber to the surface anatomy of the spinal cord and meninges. (United States)

    Rengachary, Setti S; Pelle, Dominic; Guthikonda, Murali


    From prehistoric times, man has been aware that injury to the spine may result in paralysis of the limbs; this is reflected in bas-relief figures found at Nineweh in ancient Mesopotamia, in a hunting scene that depicts a lioness wounded by King Ashurbanipal. The Edwin Smith papyrus gives many case illustrations of spinal cord injury resulting in paralysis, yet early physicians were unaware of the anatomy of the spinal cord. Galen performed prospective studies in animals by sectioning the spinal cord at varying levels and observing the commensurate paralysis and sensory loss. Real advances in the understanding of spinal cord anatomy did not occur until human cadaveric dissections were undertaken; even then, the knowledge of the anatomy of the spinal cord lagged behind that of other body structures. Johann Jacob Huber appears to be the first anatomist to focus on the spinal cord almost exclusively. His descriptions, and especially his illustrations that depict spinal cord surface anatomy, are impressive with regard to their accuracy and their sense of photorealism. Indeed, his illustrations seem to compare well with the anatomic drawings in contemporary anatomic texts. Yet, we were unable to find a single article in the entire English-language literature depicting his illustrations. We conclude that the description and anatomic illustrations by Johann Jacob Huber remain a hidden gem in the history of human spinal anatomy. PMID:18825005

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

    International Nuclear Information System (INIS)

    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

  16. A magpie with a card-index mind - Charles Davies Sherborn 1861-1942. (United States)

    Shindler, Karolyn


    Charles Davies Sherborn was geologist, indexer and bibliographer extraordinaire. He was fascinated by science from an early age and like so many Victorians, the young Sherborn was a passionate natural history collector and was obsessed with expanding his collection of land and freshwater shells. He later described himself as being a 'thorough magpie' and having 'a card-index mind', and these two traits coalesced in his monumental Index Animalium, the compilation of which occupied 43 years of his life. One of the first visitors through the doors of the Natural History Museum in South Kensington when it opened in 1881, Sherborn began work there seven years later as one of the small band of unofficial scientific workers, paid by the number of fossils he prepared. By the time of his death in 1942, Sherborn's corner in the Museum was the first port of call for generations of scientists seeking advice, information - or an invitation to one of his famous 'smoke and chat' parties. In addition to his work on the Index, Sherborn is also responsible for rescuing from damp and probable destruction the huge archive of Sir Richard Owen, the great comparative anatomist and the prime mover behind the creation of the Natural History Museum, London. Without Sherborn, this invaluable resource of correspondence, manuscripts and books may well have been irretrievably ruined. PMID:26877651

  18. Andreas Vesalius' understanding of pulmonary ventilation. (United States)

    Hage, J Joris; Brinkman, Romy J


    The historical evolution of understanding of the mechanical aspects of respiration is not well recorded. That the anatomist Andreas Vesalius (1515-1564) first recorded many of these mechanics in De Humani Corporis Fabrica Libri Septem has received little attention. We searched a digital copy of De Fabrica (1543) and its English translation as provided by Richardson and Carman (1998-2009) for references to aspects of pulmonary ventilation. We found that Vesalius grasped the essentials of tidal and forced respiration. He recognized that atmospheric pressure carried air into the lungs, approximately 100 years before Borelli did. He described an in vivo experiment of breathing, some 120 years before John Mayow produced his artificial model. He reported on positive pressure ventilation through a tracheotomy and on its life-saving effect, some 100 years before Robert Hook did. In publicly recording his insights over 450 years ago, Vesalius laid a firm basis for our understanding of the physiology of respiration and the management of its disorders. PMID:27238371

  19. Web-delivery of anatomy video clips using a CD-ROM. (United States)

    Bacro, T; Gilbertson, B; Coultas, J


    Until recently, anatomists had no doubt that the teaching of anatomy had to include cadaver dissection. However, due to a changing academic environment as well as challenged financial institutional resources, computer-assisted instruction was introduced into medical curriculum in an attempt to reduce the cost and the time committed to cadaver dissection. Computer-assisted instruction included locally created or commercially available anatomy software, Internet sites, and databases of digital images of cadaveric structures such as the Virtual Human Project. However, until now, bandwidth limitations have not allowed effective visualization in real-time over the Internet of recorded videos or 3D animations reconstructed from a database. We describe how to successfully link and display large video clips stored on a CD-ROM in support of lectures saved in HTML format on the Internet. This process, described in its totality, allows students to access audiovisual files on a CD-ROM through the Internet, from any location, with either Macintosh or Windows computers, using the Netscape browser. This process allowed us to circumvent one of the most significant limitations of the computer-assisted instruction on the Internet by delivering full audio and visual information on demand, as it would happen in a traditional classroom.

  20. 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.

  1. Morphometric study of styloid process of temporal bone in Indian adult dry skull

    Directory of Open Access Journals (Sweden)

    Sarita Ramlu Margam


    Methods: Study was carried out on 70 (50 males, 20 females adult dry skulls. All measurements such as length, direction, thickness at base of styloid process, distance between of two processes, and distance between it and stylomastoid foramen were taken with the help of vernier caliper in millimeters. Results: We found mean length of styloid process in males on right side 17.8 mm and on left 15.4 mm. In females, it was 13 mm on right and 16.8 mm on left side. Average distance between of two styloid processes at base was 68.13 mm in males and 67.42 mm in females. Thickness at the base of styloid process, in males on right 4.53 mm and on left side it was 4.83 mm while in females on right 4.33 mm and on left side it was 5 mm. Conclusions: Neurovascular structures which lie within the territory of styloid process may be compressed due to its anatomical variation. This data may be useful for clinicians, surgeons, radiologists, anesthetists and anatomists as an academic interest. [Int J Res Med Sci 2015; 3(6.000: 1348-1352

  2. 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.

  3. Posterior approach to kidney dissection: An old surgical approach for integrated medical curricula. (United States)

    Daly, Frank J; Bolender, David L; Jain, Deepali; Uyeda, Sheryl; Hoagland, Todd M


    Integrated medical curricular changes are altering the historical regional anatomy approach to abdominal dissection. The renal system is linked physiologically and biochemically to the cardiovascular and respiratory systems; yet, anatomists often approach the urinary system as part of the abdomen and pelvic regions. As part of an integrated curriculum, the renal system must be covered relatively quickly after the thorax in the cadaver laboratory, often without the opportunity to fully appreciate the rest of the abdominal contents. This article provides dissection instructions that follow one of the historical surgical approaches for nephrectomy, including preservation of the posterior abdominal wall neurovasclature. Dissection procedures were developed for first-year medical students, intending this posterior approach to the kidneys to be their first introduction to the renal system. It has been successfully implemented with the first-year medical students at the University of New England, College of Osteopathic Medicine. Utilizing this posterior approach to the kidney enabled the study of the anatomy of the kidneys, suprarenal glands, and renal vessels, as well as the muscles of the lumbar spine, while maintaining the integrity of the anterior abdominal wall and peritoneal cavity for future gastrointestinal and reproductive system-based dissections.

  4. Clarifying the anatomy of hearts with concordant ventriculo-arterial connections but abnormally related arterial trunks. (United States)

    Gupta, Saurabh K; Ramakrishnan, Sivasubramanian; Gulati, Gurpreet S; Henry, G William; Spicer, Diane E; Backer, Carl L; Anderson, Robert H


    Hearts in which the arterial trunks arise from the morphologically appropriate ventricles, but in a parallel manner, rather than the usual spiralling arrangement, have long fascinated anatomists. These rare entities, for quite some time, were considered embryological impossibilities, but ongoing experience has shown that they can be found in various segmental combinations. Problems still exist about how best to describe them, as the different variants are often described with esoteric terms, such as anatomically corrected malposition or isolated ventricular inversion. In this review, based on our combined clinical and morphological experience, we demonstrate that the essential feature of all hearts described in this manner is a parallel arrangement of the arterial trunks as they exit from the ventricular mass. We show that the relationship of the arterial roots needs to be described in terms of the underlying ventricular topology, rather than according to the arrangement of the atrial chambers. We then discuss the importance of determining atrial arrangement on the basis of the morphology of the appendages, following the precepts as set out in the so-called "morphological method" and distinguished according to the extent of the pectinate muscles relative to the atrioventricular junctions as opposed to basing diagnosis on the venoatrial connections. We show that, when approached in this manner, the various combinations can be readily diagnosed in the clinical setting and described in straightforward way. PMID:26311213

  5. A scoring framework for assessing anatomy competence of undergraduate preclinical students. (United States)

    Raubenheimer, Daleen; Raubenheimer, Jacques Eugene; van Zyl, Sanet


    Recent higher education changes toward outcomes-based education emphasize competent learners, but a widely accepted definition of competence is still lacking. Although the importance of anatomy in health professions education is recognized, there is still uncertainty about what anatomical competence entails and how to assess it. This study aimed to provide a framework for assessing anatomical competence, using an anatomy competence score, for the anatomy course in the undergraduate medical learning program at the University of the Free State in South Africa. All assessments within the dissection program of two student groups (July 2012 to June 2014) were explored to determine the representation of the three competence domains: knowledge, skill and application in context. Student performance in the final objective structured practical examination (OSPE) was investigated for the three domains and the different body regions. Knowledge had ±50% representation in assessments and the different body regions (in final OSPE) for both groups, and skill and application represented ±25% each in both groups. The best average student performance was in the skill domain (64% and 67% for the respective groups). All domains showed good reliabilities (> 0.75) and student performance correlated well between the domains (P competence assessment. However, this ratio depends on the assessment type, the stage of the anatomy course and the institutional context. Nonetheless, it provides a guideline for ensuring that assessments address all competence domains. Anat Sci Educ 9: 319-329. © 2015 American Association of Anatomists. PMID:26588194

  6. The Nerve Supply of the Bone Marrow in Different Laboratory Animals

    International Nuclear Information System (INIS)

    The proliferation and release of the different types of cells from the bone marrow presents so many obscurities in the explanation of the maintenance of homeostasis at the level of the blood corpuscles that one wonders if this difficulty is due to a lack of information in some important area. The function of an organ, and the influence that other organs may have on its physiological and pathological changes, cannot be understood if the role of the nervous system and the hormones are not taken into consideration; but when we study the bone marrow and speak about its function as a blood-forming organ, the nervous system is continually ignored. The situation is such that the first question that comes to mind is this: Are there nerves in the bone marrow? The answer of the old anatomists was: Yes. The description of nerves entering into the bone cavity can be found in papers published more than one hundred years ago, but the description of their distribution and relation with the different elements of the marrow is vague and contradictory. Consequently we considered it worthwhile to study the problem of the innervation of the bone marrow anew

  7. The Cajal School in the Peripheral Nervous System: The Transcendent Contributions of Fernando de Castro on the Microscopic Structure of Sensory and Autonomic Motor Ganglia (United States)

    de Castro, Fernando


    The fine structure of the autonomic nervous system was largely unknown at the beginning of the second decade of the 20th century. Although relatively anatomists and histologists had studied the subject, even the assays by the great Russian histologist Alexander Dogiel and the Spanish Nobel Prize laureate, Santiago Ramón y Cajal, were incomplete. In a time which witnessed fundamental discoveries by Langley, Loewi and Dale on the physiology of the autonomic nervous system, both reputed researchers entrusted one of their outstanding disciples to the challenge to further investigate autonomic structures: the Russian B.I. Lawrentjew and the Spanish Fernando de Castro developed new technical approaches with spectacular results. In the mid of the 1920’s, both young neuroscientists were worldwide recognized as the top experts in the field. In the present work we describe the main discoveries by Fernando de Castro in those years regarding the structure of sympathetic and sensory ganglia, the organization of the synaptic contacts in these ganglia, and the nature of their innervation, later materialized in their respective chapters, personally invited by the editor, in Wilder Penfield’s famous textbook on Neurology and the Nervous System. Most of these discoveries remain fully alive today. PMID:27147984

  8. Dissection and dissection-associated required experiences improve student performance in gross anatomy: Differences among quartiles. (United States)

    Pizzimenti, Marc A; Pantazis, Nicholas; Sandra, Alexander; Hoffmann, Darren S; Lenoch, Susan; Ferguson, Kristi J


    To promote student learning, educational strategies should provide multiple levels of engagement with the subject matter. This study investigated examination data from five first year medical gross anatomy class cohorts (692 students) to determine if enhanced student performance was correlated with learning through dissection in a course that used a rotating dissection schedule coupled with peer teaching and other associated experiences. When students performed two of five weekly dissections for a given unit, their average scores on both laboratory and written examinations tended to increase as compared to when they had completed only one week of dissection (P Students in the upper quartile (UQS) of the class benefited when they had dissected once (92.8%) or twice (92.4%), and these scores were significantly higher than those attained when learning from peers (90.3%, P Students in the lower quartile (LQS) benefited most from the dissection experiences, where practical examination performance was better (77.8% and 80.5%) than when these students learned material from their peers (73.7%, P < 0.01). Although UQS benefited from dissection, LQS benefited to a greater extent in both the practical and written examinations with dissection. Although limited, these data suggest that dissection, coupled with associated educational activities, is an effective pedagogical strategy for learning. Further investigation is required to evaluate the concomitant benefits of peer teaching that are associated with the dissection experience.

    Bhanu SP


    Full Text Available The anatomical variations in the formation, course and termination of brachial plexus are well documented and have clinical significance to surgeons, neurologists and anatomists. The present case report describes the unusual origin of median nerve, arising directly from the lateral cord without the union of lateral and medial roots of brachial plexus. A communicating branch existed between the ulnar nerve and anterior division of middle trunk. The lateral pectoral nerve was arising from anterior divisions of upper and middle trunks as two separate branches instead from lateral cord. The branches then joined together to form the lateral pectoral nerve. The medial cord instead of its five terminal branches, had only three branches, the ulnar nerve, medial pectoral nerve and a single trunk for the medial cutaneous nerve of arm and forearm which got separated at the middle of the arm. The variations of the lateral cord and its branches make it a complicated clinical and surgical approach which is discussed with the developmental background.

  10. Humphrey Ridley (1653-1708): forgotten neuroanatomist and neurophysiologist. (United States)

    Veith, Philip; Watanabe, Koichi; Shoja, Mohammadali M; Blaak, Christa; Loukas, Marios; Tubbs, R Shane


    Humphrey Ridley is a little known character in the history of anatomy and physiology. Born in 1653, Ridley was a physician and anatomist who followed the research done by Willis, Vieussens, and Galen. Outside of a cursory knowledge of his birth and death, readers have only two remnants of his contributions to science: The Anatomy of the Brain, containing its Mechanism and Physiology and Observationes Quaedam Medico-Practicae et Physiologicae de Asthmate et Hydrophobia. The former text was the first book in the English language written on the human brain. Ridley's studies using cadavers executed by hanging provided him with a novel view of the venous drainage and lymphatic system not seen as accurately by those before him. Since the study of the brain was still largely in its infancy, he was not without his errors of deduction as to the purpose of parts of the brain and its pathologies. With his dissections, however, Ridley was able to build on the collective knowledge of neuroanatomy and provided new insight into brain structure and function. The current paper reviews what is known of Ridley's life and contributions to neuroanatomy and neurophysiology. PMID:23362140

    Full Text Available Introduction: A variety of malformations are included under the description of Neural tube defects (NTDs. These are abnormalities of the embryonic neuralization process. The congenital malformations of human structure and are of great interest to anatomists, obstetricians, pediatricians and radiologists. NTDs are among the commonest and most severe disorders, affecting 0.5-2 per 1000 established pregnancies, and are second commonest group of birth defects, after congenital heart defects. A valuable contribution of this study, the neural tube defects aimed at clinical methods and refined for the prenatal diagnosis in utero. Materials and Methods: This comprehensive study was undertaken to know the incidence of detail knowledge of neural tube defects in KIMS Narketpally and KAMS & RC Hyderabad, among 1000 births during the period of two years. We found seven fetuses with neural tube defects involving brain and spinal cord. A detailed study was done emphasizing on embryology and genetic and non-genetic concepts. Results & Conclusion: The seven fetuses were stillbirths and aborted babies between 20 to 40 weeks, presented with neural tube defects (0.7%. Five fetuses were females and two fetuses were males. The spinal defects were 0.4%, cranial defects 0.2% and complete neural tube defects is 0.1%. This review article discusses the classification, clinical research and epidemiological understanding of NTDs and correlated with the available literatures.

  12. Development of a Burn Escharotomy Assessment Tool: A Pilot Study. (United States)

    Ur, Rebecca; Holmes, James H; Johnson, James E; Molnar, Joseph A; Carter, Jeffrey E


    Severe burn injuries can require escharotomies which are urgent, infrequent, and relatively high-risk procedures necessary to preserve limb perfusion and sometimes ventilation. The American Burn Association Advanced Burn Life Support© course educates surgeons and emergency providers about escharotomy incisions but lacks a biomimetic trainer to demonstrate, practice, or provide assessment. The goal was to build an affordable biomimetic trainer with discrete points of failure and pilot a validation study. Fellowship-trained burn and plastic surgeons worked with special effect artists and anatomists to develop a biomimetic trainer with three discrete points of failure: median or ulnar nerve injury, fasciotomy, and failure to check distal pulse. Participants were divided between experienced and inexperienced, survey pre- and post-procedure on a biomimetic model while being timed. The trainer total cost per participant was less than $35. Eighteen participants were involved in the study. The inexperienced (0-1 prior escharotomies performed) had significantly more violations at the discrete points of failure relative to more experienced participants (P = .036). Face validity was assessed with 100% of participants agreement that the model appeared similar to real life and was valuable in their training. Given the advancements in biomimetic models and the need to train surgeons in how to perform infrequent, emergent surgical procedures, an escharotomy trainer is needed today. The authors developed an affordable model with a successful pilot study demonstrating discrimination between experienced and inexperienced surgeons. Additional research is needed to increase the reliability and assessment metrics. PMID:26594860

  13. 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.

  14. 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.

  15. 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.

  16. Learning from mistakes: early twentieth-century surgical practice. (United States)

    Wilde, Sally; Hirst, Geoffrey


    Archibald Watson was an Australian anatomist and surgeon who kept operating theater diaries. He made detailed notes on the work of surgeons that he observed in Britain and North America, as well as in Australia. Watson's diaries provide significant evidence that early twentieth-century surgeons did not just apply scientific knowledge produced somewhere else. They generated new surgical knowledge themselves and worked within a culture that valued innovation. Some of the surgeons observed by Watson practiced in academic centers and regularly engaged in laboratory research, but most did not. Nevertheless, it is clear that whether in Australia, Britain, or North America, the active search for improved techniques was a routine feature of the practice of full-time surgeons. In the process, they often made mistakes--or rather, they often did things with which at least some of their colleagues did not agree. Much of surgical practice was contestable. Doing things the "right" way and finding better ways to do things were overlapping categories; but it is often difficult or impossible to draw any distinction at all between doing things the "wrong" way and failed attempts at finding a better way to perform an operation. This article examines some aspects of the relationship between scientific ideas, clinical experience, contestable errors, and the generation of new knowledge through surgical practice.

In addition to this, it is also important for anatomist during routine classroom dissection and discussion.

  18. Notes on the history of the Dr. Senckenbergische Anatomie in Frankfurt/Main. Part II. The Dr. Senckenbergische Anatomie during the Third Reich and its body supply. (United States)

    Brehm, Thomas Theo; Korf, Horst-Werner; Benzenhöfer, Udo; Schomerus, Christof; Wicht, Helmut


    In order to be able to understand how body supply was maintained at the Dr. Senckenbergische Anatomie from 1933 to 1945 - with special emphasis on victims of the National Socialist regime - we have collected information from various and often fragmentary sources. The documents reveal that during this period at least 474 bodies were brought to the anatomical institute. Among them were the bodies of at least 71 prisoners, 51 of whom had been executed, and the bodies of 8 inmates of (labor-) camps. 356 unclaimed bodies were received, some of them may stem from victims of "euthanasia" programs. The sources of 39, as of yet, unnamed bodies could not be verified. The current collections and the catalogs were screened for remains of victims of the National Socialist regime, but none were found. The vast majority of the bodies were used for teaching purposes. Hans Schreiber, one of the directors of the institute, whose biography is provided here, used at least 9 additional executed individuals for his research. Wherever possible, we have identified the victims of the National Socialist regime, executed persons and the inmates of (labor-) camps, whose bodies were used by the anatomists in Frankfurt, by name. Among the victims was Georg Fröba, a communist philanthropist, whose biography is provided. PMID:26198687

  19. 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.

  20. 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.

  1. Nuclear Medicine in India

    Directory of Open Access Journals (Sweden)

    R.D. Lele


    Full Text Available The regular supply of radiopharmaceuticals and radioimmunoassay kits from BARC has been an important factor in the development of nuclear medicine in India. However, a major stumbling block has been the non-availability of suitable instrumentation systems (especially the computer-assisted gamma camera at an affordable price. Two recent developments, viz., the creation of the Board of Radioisotope Technology by the Department of Atomic Energy, and the efforts of Electronic Corporation of India Ltd. to design indigenously a gamma camera with a computer attachment, hold promise for the future healthy and rapid growth of nuclear medicine in the country. Training in nuclear medicine at the post-graduate level is gradually picking up. Nuclear medicine is essentially applied physiology and biochemistry, and provides an orientation, different from those of the anatomist and physiologist. The gamma camera, SPECT and PET enable the study of dynamic metabolic function resolution to spatial and temporal resolutions. Newer developments in tagged monoclonal antibodies hold promise for a better understanding of infectious and inflammatory disease which are a burden in the developing countries.

  2. The Clara cell: a "Third Reich eponym"? (United States)

    Winkelmann, A; Noack, T


    German anatomist Max Clara (1899-1966) described the "Clara cell" of the bronchiolar epithelium in 1937. The present article investigates Clara's relationship with National Socialism, as well as his use of tissue from executed prisoners for research purposes, details about both of which are largely unknown to date. Our methodology for the present study focussed on analysis of material from historical archives and the publications of Clara and his co-workers. Clara was appointed as Chair of Anatomy at Leipzig University (Leipzig, Germany) in 1935. He owed his career, at least in part, to Nazi support. He was an active member of the Nazi party (Nationalsozialistische Deutsche Arbeiterpartei (NSDAP)) and engaged in university politics; this included making anti-Semitic statements about other academics in appointment procedures. Nevertheless, he also supported prosecuted colleagues. Much of Clara's histological research in Leipzig, including his original description of the bronchial epithelium, was based on tissue taken from prisoners executed in nearby Dresden (Germany). Max Clara was an active and outspoken Nazi and his histological research exploited the rising number of executions during the Nazi period. Clara's discovery is thus linked to the Nazi system. The facts given in the present paper invite discussion about the eponym's neglected history and its continued and problematic use in medical terminology. PMID:20223917

  3. 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. This collection, a work in progress, is available at PMID:14750190

  4. [Claudio Galeno and the lateral ventricles]. (United States)

    Martínez, F; Decuadro-Sáenz, G


    Galen of Pergamon is considered one of the fathers of occidental medicine. Because of cultural and religious precepts at his time, many authors hypothesize that the anatomical concepts of Galen were derived from dissection of monkeys. In this paper, the authors analyzed the ventricular system, according to the anatomic and functional concepts described by Galen's early work. Knowing that his work was derived and or influenced from other preceding anatomists and physicians (specially Hipocrates of Cos), we present our investigation in two parts. In the first part, we present the influences of previous religious, philosophic, medical and anatomical theories over the galenic work. The "pregalenic era" can be divided in three periods: 1) the pretecnic era (ending in VI BC) in which the man have only a rudimentary knowledge of human anatomy, 2) the hellenistic science (from VI to III BC) and 3) the period comprised between III BC to Galenic period. In each of the three periods, we analyzed the neuroanatomic knowledge of the most important cultures. PMID:18335157

  5. Understanding the current anatomical competence landscape: Comparing perceptions of program directors, residents, and fourth-year medical students. (United States)

    Fillmore, Erin P; Brokaw, James J; Kochhar, Komal; Nalin, Peter M


    A mixed methods survey of fourth-year medical students, resident physicians, and residency program directors at the Indiana University School of Medicine gathered perceptions of anatomical competence-defined as the anatomical education necessary for effective clinical practice. The survey items explored numerous aspects of anatomical competence, including the most effective modes of instruction, perceptions of readiness for clinical practice, and specific suggestions for improving anatomical education during medical school and residency. The response rate was 46% for fourth-year medical students, 47% for residents (as graduates from 137 medical schools), and 71% for program directors. A majority of students and residents reported that their course in Gross Anatomy prepared them well for clinical practice; that cadaveric dissection was important in the early development of their anatomical competence; and that placing a greater emphasis on clinical relevance in medical school would have improved their anatomical competence even further. However, in terms of anatomical preparedness upon entering residency, the program directors rated their residents less prepared than the residents rated themselves. All three groups agreed that there is need for additional opportunities for anatomical educational during medical school and residency. Suggestions for improving anatomical education included the following: providing more opportunities for cadaveric dissection during medical school and residency; more consistent teaching of anatomy for clinical practice; more workshops that review anatomy; and better integration of anatomy with the teaching of other subjects during medical school.

  6. 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.

  7. 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. PMID:24879053

  8. 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.

  9. Who is repeating anatomy? Trends in an undergraduate anatomy course. (United States)

    Schutte, Audra F


    Anatomy courses frequently serve as prerequisites or requirements for health sciences programs. Due to the challenging nature of anatomy, each semester there are students remediating the course (enrolled in the course for a second time), attempting to earn a grade competitive for admissions into a program of study. In this retrospective study, remediation rates and trends in an undergraduate anatomy course with over 400 students enrolled each semester at a large Midwestern university were identified. Demographic data was collected from spring 2004 to spring 2010, including students' age, ethnicity, major of study, class standing, college admission tests (ACT and SAT®) scores, anatomy laboratory and lecture examination scores, and final anatomy grades for each semester. Eleven percent of the students repeated the course at least once. Gender, ethnicity, major of study and SAT scores were all shown to be associated with whether or not a student would need to repeat the course. On average, students who repeated anatomy demonstrated significant improvements in lecture and laboratory scores when comparing first and second enrollments in anatomy, and therefore also saw improved final course grades in their second enrollment. These findings will aid future instructors to identify and assist at-risk students to succeed in anatomy. Instructors from other institutions may also find the results to be useful for identifying students at risk for struggling. Anat Sci Educ 9: 171-178. © 2015 American Association of Anatomists.

    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.

  11. 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. PMID:25308536

  12. 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. PMID:19941362

  13. 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. PMID:23564745

  14. [The painting 'The anatomical lesson by Professor Louis Bolk' by Martin Monnickendam]. (United States)

    Baljet, B


    In 1992 the painting 'The anatomy of professor Louis Bolk' by the Dutch painter Martin Monnickendam (1874-1943), was finally returned to its place in the 'Tulp-room' of the Department of Anatomy and Embryology at the University of Amsterdam, after the department had been moved to new premises in 1985. The professor of anatomy at the University of Amsterdam, Louis Bolk, is seated in the middle surrounded by his, at that time, former pupils, from left to right: Boeke, Barge and van den Broek, authors of a Dutch textbook of anatomy. The four professors are gathered around a cadaver of an orang-utan, placed not on a dissection table but on a console. Bolk is facing the observer and holding a scalpel in one hand while steadying the animal's head with the other; he is ready to make an incision. In the back of the painting a bust of the 18th century anatomist Petrus Camper is visible. The four professors all wear a white coat over their suits. Bolk finishes this off with an artistic bow tie whilst the others use an ordinary necktie. The painting is signed in the left upper corner 'Martin Monnickendam 1925'. PMID:8277996

    Full Text Available Background: The mental foramen is one of the two holes ("foramina" located on the anterior surface of the mandible. It permits passage of the mental nerve and vessels. The mental foramen descends slightly in edentulous individuals. Methods: The present study was carried out in the department of anatomy on 70 Adult North Indian dry Mandibles of unknown age and sex which were obtained from the osteology section of Integral Institute of Medical Sciences and Research & King George medical university. The Mandibles were observed macroscopically for the presence of mental foramen. Results: In our study we observed that the oval shape of mental foramen was 87.1% on right side and 88.6% on left side. Round mental foramen was observed to be 12.9% on the right side and 11.4% on left side. The Position of Mental foramen in relation to borders left side were found Central (87.1%, upper border (7.1%, lower side (5.7% and right side Central (85.7% , upper border (10% and lower side (4.3%. Conclusions: Knowledge of the mental foramen and it’s variation in different population is essential for dentists, orthopedicians and anatomists. A future prospect of interest lies in their possible contribution to the maxillofacial anthropologic characteristic identification for different population and races.

  16. 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 implementation within a larger electronic learning management system needs to be explored in future research.

  17. Malrotation and midgut volvulus: a historical review and current controversies in diagnosis and management

    International Nuclear Information System (INIS)

    The complex and sometimes controversial subject of malrotation and midgut volvulus is reviewed commencing with the 19th-century Bohemian anatomist, Vaclav Treitz, who described the suspensory muscle anchoring of the duodenal-jejunal junction in the left upper quadrant, and continuing with William Ladd, the 20th-century American ''father of pediatric surgery'' who pioneered the surgical treatment of midgut volvulus. In this review, we present the interesting history of malrotation and discuss the current radiologic and surgical controversies surrounding its diagnosis and treatment. In the symptomatic patient with malrotation and possible midgut volvulus, prompt diagnosis is critical. The clinical examination and plain film are often confusing, and delayed diagnosis can lead to significant morbidity and death. Despite recent intense interest in the position of the mesenteric vessels on US and CT scans, the upper gastrointestinal series remains the fastest and most accurate method of demonstrating duodenal obstruction, the position of the ligament of Treitz, and, if the contrast agent is followed distally, cecal malposition. Controversy exists over the management of asymptomatic patients with malrotation in whom the diagnosis is made incidentally during evaluation for nonspecific complaints, prior to reflux surgery, and in those with heterotaxy syndromes.

    Carrillo Esper, Raúl; Carrillo Córdova, Luis Daniel; Carrillo Córdova, Dulce María; Carrillo Córdova, Carlos Alberto; Carrillo Córdova, Jorge Raúl


    In the sixteenth century there were great advances in science, literature, and the arts. During this century, urology as a specialty was conceived, thanks to the contributions of Andreas Vesalius, anatomist and leading physician to the court of Charles V, and Dr. Francisco Diaz, a native of Alcala de Henares, surgeon and clinician. Dr. Diaz had a close relationship with Miguel de Cervantes, who at one point in his life suffered from renal colic. In his masterpiece "Re-Printed Treaty of all diseases of the kidneys, bladder and wattles of the Cock and Urina, divided into three books," of which the first book of urology is the History of Medicine, describes in detail the clinical and therapeutic aspects of urological diseases, known as the "bad stone" and urethral strictures known as "wattles", in addition to describing the different surgical techniques and the development of new instruments for urological procedures, which include the cisorio instrument and the Speculum pudendi. For the above, Dr. Francisco Diaz is considered the father of urology. PMID:26290034

  19. [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. PMID:27487699

    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 x 1 x 1 mm{sup 3} 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.

  1. 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.

  2. A histological study of prostate

    Ashfaq U. Hassan


    Full Text Available The work of anatomists and pathologists in the role of study of prostate has been significant. Starting from earlier times till modern time, the study of prostate has been a dynamic one and the basic anatomical knowledge of the prostate has undergone much change apart from the new techniques, micro invasive procedures and the chemotherapeutic approach for various disorders of the gland. The present study was based on the microscopic examination of Prostatic tissue of individuals with individual tissues of different age groups. The present study involved 40 cases which were further subdivided into various age groups and characteristic histological changes were noted. The study presents an assessment of age changes in prostate in elderly in Kashmiri population with pathological significance. Besides the histological study is of great importance in staging of diseases of prostate and especially in modern era where the incidence and prevalence of prostatic diseases is on rise.

  3. Irregular geometries in normal unmyelinated axons: a 3D serial EM analysis. (United States)

    Greenberg, M M; Leitao, C; Trogadis, J; Stevens, J K


    Axons have generally been represented as straight cylinders. It is not at all uncommon for anatomists to take single cross-sections of an axonal bundle, and from the axonal diameter compute expected conduction velocities. This assumes that each cross-section represents a slice through a perfect cylinder. We have examined the three-dimensional geometry of 98 central and peripheral unmyelinated axons, using computer-assisted serial electron microscopy. These reconstructions reveal that virtually all unmyelinated axons have highly irregular axial shapes consisting of periodic varicosities. The varicosities were, without exception, filled with membranous organelles frequently including mitochondria, and have obligatory volumes similar to that described in other neurites. The mitochondria make contact with microtubules, while the other membraneous organelles were frequently found free floating in the cytoplasm. We conclude that unmyelinated axons are fundamentally varicose structures created by the presence of organelles, and that an axon's calibre is dynamic in both space and time. These irregular axonal geometries raise serious doubts about standard two dimensional morphometric analysis and suggest that electrical properties may be more heterogeneous than expected from single section data. These results also suggest that the total number of microtubules contained in an axon, rather than its single section diameter, may prove to be a more accurate predictor of properties such as conduction velocity. Finally, these results offer an explanation for a number of pathological changes that have been described in unmyelinated axons. PMID:2292722

  4. The prevalence of the extensor digiti minimi tendon of the hand and its variants in humans: a systematic review and meta-analysis. (United States)

    Yammine, Kaissar


    The extensor digiti minimi (EDM) is frequently used in the case of an abduction deformity of the little finger. It is also considered as a main resource for tendon transfer. However, it shows many variations in the human hand, which include splitting into two or more slips and sending a slip to the fourth finger, named the extensor digiti minimi et quarti (EDMQ). The aim of this systematic review is to perform an evidence synthesis on the prevalence of the EDM and its variants. Twenty-six cadaveric studies met the inclusion criteria with a total of 2247 hands. Meta-analysis results yielded an overall pooled prevalence estimate (PPE) of the EDM of 99.7% and PPEs of 11.5, 77.6, 7 and 0.6% for the single-, double-, triple- and quadruple-slip EDM, respectively. For the single-slip EDM, the frequencies were such that Indians > Middle Eastern > Europeans > Japanese > North Americans. For the double-slip EDM, the frequencies were such that Japanese > North Americans = Europeans > Middle Eastern > Indians. No significance was found with regard to hand side. The true EDMQ prevalence was found to be at 7.3%, whereas its crude prevalence was 8%. This artilce offers reference values on the prevalence of the EDM and its variants, which are thought to be highly relevant to both anatomists and clinicians. PMID:25217141

  5. 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. PMID:19892123

  6. Digital dissection system for medical school anatomy training (United States)

    Augustine, Kurt E.; Pawlina, Wojciech; Carmichael, Stephen W.; Korinek, Mark J.; Schroeder, Kathryn K.; Segovis, Colin M.; Robb, Richard A.


    images are captured automatically, and then processed to generate a Quicktime VR sequence, which permits users to view an object from multiple angles by rotating it on the screen. This provides 3-D visualizations of anatomy for students without the need for special '3-D glasses' that would be impractical to use in a laboratory setting. In addition, a digital video camera may be mounted on the rig for capturing video recordings of selected dissection procedures being carried out by expert anatomists for playback by the students. Anatomists from the Department of Anatomy at Mayo have captured several sets of dissection sequences and processed them into Quicktime VR sequences. The students are able to look at these specimens from multiple angles using this VR technology. In addition, the student may zoom in to obtain high-resolution close-up views of the specimen. They may interactively view the specimen at varying stages of dissection, providing a way to quickly and intuitively navigate through the layers of tissue. Electronic media has begun to impact all areas of education, but a 3-D interactive visualization of specimen dissections in the laboratory environment is a unique and powerful means of teaching anatomy. When fully implemented, anatomy education will be enhanced significantly by comparison to traditional methods.

  7. In vivo organ mass of Korean adults obtained from whole-body magnetic resonance data

    International Nuclear Information System (INIS)

    In vivo organ mass of the Korean adult, male and female were presented for the purpose of radiation protection. A total of 121 healthy volunteers (66 males and 55 females), whose body dimensions were close to that of average Korean adults, were recruited for this study. Whole-body magnetic resonance (MR) images were obtained, and contours of 15 organs (brain, eye, gall bladder, heart, kidney, liver, lung, pancreas, stomach, spleen, testes, thymus, thyroid, urinary bladder and uterus) and 9 bones (femur, tibia + fibula, humerus, radius + ulna, pelvis, cervical spine, thoracic and lumber spine, skull and clavicle) were segmented for organ volume rendering by anatomists using commercial software. Organ and bone masses were calculated by multiplying the Asian reference densities of the corresponding organs and bones by the measured volumes. The resulting organ and bone masses were compared with those of the International Commission of Radiological Protection (ICRP) and the Asian reference data. Significantly large standard deviation was shown in the moving organs of the respiratory and circulatory systems and in the alimentary and urogenital organs that are variable in volume in a single person. Gall bladder and pancreas showed unique Korean organ masses compared with those of ICRP and the Asian reference adults. Different from anatomical data based on autopsy, the in vivo volume and mass in this study can more exactly describe the organ volume of a living human subject for radiation protection. A larger sample size would be required for obtaining statistically more reliable results. It is also needed to establish the reference organ mass of younger age groups for which it is difficult to recruit volunteers and to immobilise the subjects for long-time MR scanning. At present, the data from this study will contribute to the establishment of a Korean reference database. (authors)

  8. VARK learning preferences and mobile anatomy software application use in pre-clinical chiropractic students. (United States)

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


    Ubiquitous smartphone ownership and reduced face-to-face teaching time may lead to students making greater use of mobile technologies in their learning. This is the first study to report on the prevalence of mobile gross anatomy software applications (apps) usage in pre-clinical chiropractic students and to ascertain if a relationship exists between preferred learning styles as determined by the validated VARK(©) questionnaire and use of mobile anatomy apps. The majority of the students who completed the VARK questionnaire were multimodal learners with kinesthetic and visual preferences. Sixty-seven percent (73/109) of students owned one or more mobile anatomy apps which were used by 57 students. Most of these students owned one to five apps and spent less than 30 minutes per week using them. Six of the top eight mobile anatomy apps owned and recommended by the students were developed by 3D4Medical. Visual learning preferences were not associated with time spent using mobile anatomy apps (OR = 0.40, 95% CI 0.12-1.40). Similarly, kinesthetic learning preferences (OR = 1.88, 95% CI 0.18-20.2), quadmodal preferences (OR = 0.71, 95% CI 0.06-9.25), or gender (OR = 1.51, 95% CI 0.48-4.81) did not affect the time students' spent using mobile anatomy apps. Learning preferences do not appear to influence students' time spent using mobile anatomy apps. Anat Sci Educ 9: 247-254. © 2015 American Association of Anatomists. PMID:26109371

  9. Learning anatomy via mobile augmented reality: Effects on achievement and cognitive load. (United States)

    Küçük, Sevda; Kapakin, Samet; Göktaş, Yüksel


    Augmented reality (AR), a new generation of technology, has attracted the attention of educators in recent years. In this study, a MagicBook was developed for a neuroanatomy topic by using mobile augmented reality (mAR) technology. This technology integrates virtual learning objects into the real world and allow users to interact with the environment using mobile devices. The purpose of this study was to determine the effects of learning anatomy via mAR on medical students' academic achievement and cognitive load. The mixed method was applied in the study. The random sample consisted of 70 second-year undergraduate medical students: 34 in an experimental group and 36 in a control group. Academic achievement test and cognitive load scale were used as data collection tool. A one-way MANOVA test was used for analysis. The experimental group, which used mAR applications, reported higher achievement and lower cognitive load. The use of mAR applications in anatomy education contributed to the formation of an effective and productive learning environment. Student cognitive load decreased as abstract information became concrete in printed books via multimedia materials in mAR applications. Additionally, students were able to access the materials in the MagicBook anytime and anywhere they wanted. The mobile learning approach helped students learn better by exerting less cognitive effort. Moreover, the sensory experience and real time interaction with environment may provide learning satisfaction and enable students to structure their knowledge to complete the learning tasks.

    Md. Jawed Akhtar


    Full Text Available Background: Variation in number, size and shape of foramen transversarium affects the anatomical course of the vertebral vessels, which may cause pathological conditions like vertebrobasilar insufficiency. Since, inner ear derive it's blood supply from vertebral and basilar arteries, any spasm of these arteries due to irritation of sympathetic plexus, may causes labyrinthine or hearing disturbances along with neurological symptoms. The objective of present study is to study the incidence of accessory foramen transversarium in dried cervical vertebrae in Indian population and compare it with incidence among various races of world. Methods: A total of 174 cervical vertebrae (Typical-126 and Atypical-48 of unknown sex and age are analyzed to see the accessory foramen transversarium. Results: Out of the 174 cervical vertebrae, accessory foramen transversarium is found in 25 (14.36% vertebrae. Among these 25 vertebrae, 16 (9.19% are typical and 9 (5.17% are atypical cervical vertebrae. We observed in these 16 typical cervical vertebrae, 10 (5.75% vertebrae have accessory FT on right side while 3 (1.72% vertebrae have on left side and 3 (1.72% vertebrae have bilateral accessory FT. Among 9 atypical cervical vertebrae, 4 (2.3% vertebrae have accessory FT on right side while 3 (1.72% vertebrae have on left side and 2 (1.15% vertebrae have bilateral accessory FT. Accessory foramen transversarium are more common on right side in both typical and atypical cervical vertebrae. No any accessory FT is found on axis vertebra. Conclusion: Knowledge of accessory foramen transversarium is important for clinicians because it may affect the course of vertebral vessels and nerves, which causes various symptoms to patients. It is also helpful for spine surgeons in planning surgery around the cervical vertebrae and to avoid post-operative complications. These variations are also of importance and helpful for anatomist, anthropologist and radiologist. [Int J Res Med Sci

  11. Bridging the gap between basic and clinical sciences: A description of a radiological anatomy course. (United States)

    Torres, Anna; Staśkiewicz, Grzegorz J; Lisiecka, Justyna; Pietrzyk, Łukasz; Czekajlo, Michael; Arancibia, Carlos U; Maciejewski, Ryszard; Torres, Kamil


    A wide variety of medical imaging techniques pervade modern medicine, and the changing portability and performance of tools like ultrasound imaging have brought these medical imaging techniques into the everyday practice of many specialties outside of radiology. However, proper interpretation of ultrasonographic and computed tomographic images requires the practitioner to not only hone certain technical skills, but to command an excellent knowledge of sectional anatomy and an understanding of the pathophysiology of the examined areas as well. Yet throughout many medical curricula there is often a large gap between traditional anatomy coursework and clinical training in imaging techniques. The authors present a radiological anatomy course developed to teach sectional anatomy with particular emphasis on ultrasonography and computed tomography, while incorporating elements of medical simulation. To assess students' overall opinions about the course and to examine its impact on their self-perceived improvement in their knowledge of radiological anatomy, anonymous evaluation questionnaires were provided to the students. The questionnaires were prepared using standard survey methods. A five-point Likert scale was applied to evaluate agreement with statements regarding the learning experience. The majority of students considered the course very useful and beneficial in terms of improving three-dimensional and cross-sectional knowledge of anatomy, as well as for developing practical skills in ultrasonography and computed tomography. The authors found that a small-group, hands-on teaching model in radiological anatomy was perceived as useful both by the students and the clinical teachers involved in their clinical education. In addition, the model was introduced using relatively few resources and only two faculty members. Anat Sci Educ 9: 295-303. © 2015 American Association of Anatomists. PMID:26599321

  12. Vesalius and the emergence of veridical representation in Renaissance anatomy. (United States)

    Russell, Gül A


    The Renaissance marks the introduction of veridical representation of anatomical structure into printed books. For centuries, anatomy that had relied solely on textual description and the authority of the written word was transformed. An existing graphic tradition only visualized function within a humoral theory, schematically "naming the parts" or mapping the "uses of the parts" for mnemonic purposes. In the sixteenth century, anatomists and artist began to apply their knowledge and skills to present the "fabric" of the dissected human body with increasing detail and accuracy, exemplified by the naturalistic illustrations of the brain in Vesalius' De humani corporis fabrica (Basel, 1543). How did this transformation occur? Among the causal factors, the importance the humanist textual scholarship will be shown not only in the recovery of the anatomical writings of Galen (129-ca. 216), in particular, but also in providing a model in establishing anatomical "truth" by a method of "comparison." It will be argued that Vesalius' comparative approach in dissection, using both human and animal preparations against Galen's textual description, paved the way for cumulative observations of greater detail, which in turn required the representational skills of artists. An analysis of Vesalius' views between 1538 and 1543 shows a shift in the use of illustrations from serving as a visual record to compensate for limited access to cadavers in teaching, to becoming an indispensable tool to accurately convey detailed anatomical structure through the medium of printing. With the Fabrica, morphology became divorced from humoral function and enduring paradigms established that dominated until the nineteenth century. PMID:24041275

  13. 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. PMID:26475081

    Full Text Available AIM: A morphometric study of the glenoid cavity of 80 adult dry human scapulae in North Indian Population was done to evaluate the various parameters of the glenoid cavity. MATERIAL AND METHODS: This study was done on 80 dry, unpaired adult human scapulae (41 right & 39 left of unknown sex belonging to the North Indian population. Maximum superior-inferior diameter and Maximum anterior-posterior diameter of the glenoid cavity were measured and Glenoid cavity index was calculated. The shape of the glenoid cavity was classified as inverted comma shaped, pear shaped and oval shaped depending upon the presence or absence of a notch on the glenoid rim. RESULTS: The average superior-inferior diameter on right and the left sides were 34.13±3.16 mm and 34.11± 2.57 mm respectively. The average anterior-posterior diameter of the right glenoid was 24.05± 2.86 mm and that of the left was 23.36 ± 2.22 mm. The average glenoid cavity index on the right was 70.37 ± 4.08 and that of left was 68.59 ± 4.36. All values were compared with series of other workers to draw the conclusions. CONCLUSIONS: All the parameters showed a greater value for the right side. The difference seen between the values of present study and that of other workers could be explained on the basis of ethnic and racial variations. This fact may be taken into consideration while performing shoulder arthroplasty and designing glenoid prostheses in North Indian population. The current study recorded 80% of glenoid cavities having the glenoid notch, which could be useful while diagnosing different pathologies of the shoulder joint. Thus a sound knowledge of various parameters of the glenoid cavity is important for the anatomists, anthropologists, orthopaedicians and prosthetists

    Full Text Available Introduction: The word “Placenta” is a Latin word and the Greek equivalent word is “Plakons” which means “Flat cake on a plate”. The placenta is a complex multifunctional organ. It provides nutrition, gas exchange, waste removal, endocrine function and immune support. Placenta is a special circulating system to the developing foetus. Being an organ of vital importance for continuation of pregnancy and foetal nutrition it has evolved great interest among the anatomists, embryologists, pathologists and obstetricians. Materials and Methods: The study was done in 50 placentae which were collected from the department of Obstetrics and Gynaecology in collaboration with the department of Anatomy, Kamineni Institute of Medical Sciences, Narketpally, Nalgonda, Telangana, during the period of 2 years. The morphological variations of placenta, the size, shape, weight and attachment of umbilical cord with its blood vessels were observed, recorded and photographed. The prime objective of the study is to compare and evaluate the morphological alterations of placenta and umbilical cord in pregnancy. Results and Conclusion: In the current study, the majority of the placentae showed round shape, few placentae with oval and irregular and with an accessory lobe in single placenta. The current study also includes variations in insertion of umbilical cords was eccentric in majority, central, marginal and velamentous in a few. Pregnancy induced hypertension significantly affects the placenta by reducing weight and it does not have any significant effect on the shape of placenta, umbilical cord insertion and number of cotyledons on maternal surface. The placenta is the most accurate record of the infants prenatal experience.

  16. 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.

  17. Understanding brain, mind and soul: Contributions from neurology and neurosurgery

    Directory of Open Access Journals (Sweden)

    Pandya Sunil


    Full Text Available 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. 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)

    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.

  20. ['A sad and painful heart'--Andreas Vesalius as cardiologist]. (United States)

    Haneveld, G T


    One needs courage to dissociate oneself from ideas maintained for ages and put forward by authorities. How laborious this process has been for Vesalius concerning the heart, is obvious when we compare the information of an eye-witness with both editions of the De Humani Corporis Fabrica (1543 and 1555). He must have come hesitantly to the conclusion that the views on the permeability of the septum cordis, as they were supported by Galen, Mondino and Johann Winther, a professor at Louvain, could not be defended. However, they had been essential in the considerations about the blood-flow. Although Vesalius demonstrated by vivisection-experiments that a relation exists between the pulse and the heart contractions, he was not an experimenting cardiophysiologist. In this respect, he stood far behind his contemporary Leonardo da Vinci, who made experiments on heart ntractions and the bloodstream along the heart valves. Vesalius was an anatomist! And a morphologist! But he was also a physician. In this respect, he also was interested in the pathological aspects of anatomy. So he recalled in, his last book, Anatomicarum Gabrielis Fallopii Observationum Examen (1564) some cardiologically interesting patients, a.o. the courtier van Immerseel, with a very unequal pulse and "a sad and painful heart" (tristi in corde, sensu doloreve), by whom a heart abnormality was found post mortem, that in modern terms we could call "an old heart infarction with thrombus formation." According to Schenk von Grafenberg, Vesalius was dreaming of a big book about anatomo-pathology, but alas, he never wrote it. Undoubtedly he would have trusted more his eyes and less Galen: "non solum ex Galenis testimonio, sed etiam oculis ipsis perspexeris". PMID:8209581

  1. [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. PMID:6913282

  2. 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.

  3. 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.

  4. Detail microscopic analysis of deep fascia of lower limb and its surgical implication

    Bhattacharya Visweswar


    Full Text Available Background: The knowledge regarding the structural details of deep fascia remains inadequate. It was described to be relatively avascular having predominantly protective function. Anatomical and surgical studies revealed that it had associated vascular arcade and hence incorporated it to ascertain additional vascularity to the flaps. However, not much importance has been directed towards the detailed study of the various constituents of deep fascia in order to explain its physiological and clinical implications. Therefore, this study was undertaken to unveil these details. Materials and Methods: Fifty fresh specimens of human deep fascia overlying the gastrocnemius muscle were analyzed regarding the (i vasculature, (ii matrix, and (iii other structural elements. The deep fascia was procured in three forms; (a both the layers, (b superficial layer, and (c deep layer. Detail study was conducted by light, confocal, and electron microscopy. Results: Under light microscopy, blood vessels including capillaries were seen associated with both the layers. Perforators traversing the intra-fascial plane could be visualized. Confocal microscope optical sections showed well-organized bright fluorescent collagen fibers and nuclei of various cells. Electron microscopic evaluation revealed many interesting constituents which are relatively unknown to the anatomist and clinicians. There were arterioles, capillaries, venules, lymphatics, nerves, mast cells, and myofibroblasts apart from collagen and elastic fibers. Conclusion: The detail structural analysis of deep fascia provided the clue to its rich vascularity and other structural constituents. They all contribute to enhance the vascularity and maintenance of the physiological functions of fasciocutaneous, adipofascial, and fascial flaps, frequently used for reconstructions. Thus, incorporation of deep fascia in the flaps during reconstruction is highly beneficial for ensuring optimal vascularity.

  6. 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. PMID:24963785

  8. 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

  10. Association between learning style preferences and anatomy assessment outcomes in graduate-entry and undergraduate medical students. (United States)

    O'Mahony, Siobhain M; Sbayeh, Amgad; Horgan, Mary; O'Flynn, Siun; O'Tuathaigh, Colm M P


    An improved understanding of the relationship between anatomy learning performance and approaches to learning can lead to the development of a more tailored approach to delivering anatomy teaching to medical students. This study investigated the relationship between learning style preferences, as measured by Visual, Aural, Read/write, and Kinesthetic (VARK) inventory style questionnaire and Honey and Mumford's learning style questionnaire (LSQ), and anatomy and clinical skills assessment performance at an Irish medical school. Additionally, mode of entry to medical school [undergraduate/direct-entry (DEM) vs. graduate-entry (GEM)], was examined in relation to individual learning style, and assessment results. The VARK and LSQ were distributed to first and second year DEM, and first year GEM students. DEM students achieved higher clinical skills marks than GEM students, but anatomy marks did not differ between each group. Several LSQ style preferences were shown to be weakly correlated with anatomy assessment performance in a program- and year-specific manner. Specifically, the "Activist" style was negatively correlated with anatomy scores in DEM Year 2 students (rs = -0.45, P = 0.002). The "Theorist" style demonstrated a weak correlation with anatomy performance in DEM Year 2 (rs = 0.18, P = 0.003). Regression analysis revealed that, among the LSQ styles, the "Activist" was associated with poorer anatomy assessment performance (P < 0.05), while improved scores were associated with students who scored highly on the VARK "Aural" modality (P < 0.05). These data support the contention that individual student learning styles contribute little to variation in academic performance in medical students.

  12. 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 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.

  13. In-vivo endoscopic visualization of patho-anatomy in painful degenerative conditions of the lumbar spine. (United States)

    Yeung, Anthony T; Yeung, Christopher A


    The degenerative processes in an aging spine have been defined traditionally only by our knowledge of the biology of disc and facet degeneration, as well as interpretation of post-mortem cryosections by forensic anatomist Wolfgang Rauschning, M.D. In this chapter, visualization of in-vivo patho-anatomy in a degenerating disc and spinal segment is demonstrated at surgery using the Yeung Endoscopic Spine System (Y.E.S.S.), (Richard Wolf Surgical Instrument Company, Vernon Hills, IL, USA). An Institutional Review Board (IRB)-approved study of endoscopic treatment for degenerative conditions of the lumbar spine incorporated intraoperative probing under local anesthesia and endoscopic treatment of the visualized patho-anatomy. An intraoperative evocative chromo-discogram, using indigocarmine, was used to elicit discogenic pain and label the fissured and degenerative nucleus pulposus for surgical removal and thermal modulation. Painful patho-anatomy was probed in a conscious patient. The most common endoscopic finding was Inflammatory tissue in the disc and annulus. Inflammation was correlated with the presence of annular tears. Patho-physiologic changes that affect the exiting nerve, which contains the Dorsal Root Ganglion (DRG), was associated with stenotic and chemical irritation. Unavoidable postoperative dysesthesia was associated with the presence of an inflammatory membrane, and removal or thermal coagulation of "anomalous" furcal nerves in the foramen that branched off of the exiting spinal nerve. Neo-angiogenesis and neurogenesis in the inflammatory membrane present in the foraminal triangle was a new finding not reported in traditional clinical studies. Visualization and treatment of pathologic findings inside (annular tears) and outside the disc in Herniated Nucleus Pulposus (HNP), synovial cysts, foraminal stenosis, central stenosis, spondylolisthesis, is demonstrated. The endoscopic foraminal approach to the spine and disc is a technique that provides access

    The reduced use of dissection associated with the introduction of integrated systems problem-based learning curricula, graduate-entry programs and medical school expansion is a frequent topic of discussion and debate in modern medical training. The purpose of this study was to investigate the impact of these changes to the medical education landscape, by looking at the current utilization and integration of dissection in medical schools, in Australia and New Zealand. A survey and an invitation to participate in an interview were distributed to all Australian Medical Council-accredited medical schools. Sixteen schools (76%) responded to the survey and five interviews (24%) were conducted. Dissection was a component of the medical program in 12 of the 16 schools surveyed. The opportunity for medical students to dissect human cadavers was found to be related to whether the medical school was established pre- or post-2000 (P = 0.003) but was not significantly associated to undergraduate- or graduate-entry (P = 0.64), program length (P = 0.59) or the number of commencing students (P = 0.07). The methods used for the delivery and integration of dissection varied between schools. Despite substantial changes to the delivery of anatomy in Australian and New Zealand medical schools, a variety of approaches have been adopted to ensure dissection remains an integral component of medical student education. Based on our findings, a number of recommendations were formulated to encourage the integration of dissection, regardless of the didactics of the program, to enhance the anatomical knowledge of students.

  16. Understanding brain, mind and soul: Contributions from neurology and neurosurgery

    Directory of Open Access Journals (Sweden)

    Full Text Available 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.

  17. Banishing brittle bones with boron

    Energy Technology Data Exchange (ETDEWEB)

    A 6-month study indicates that boron, not even considered an essential nutrient for people and animals, may be a key to preventing osteoporosis, say nutritionist Forrest H. Nielsen and anatomist Curtiss D. Hunt at ARS' Grand Forks, North Dakota, Human Nutrition Research Center. They believe the results of the study - the first to look at the nutritional effects of boron in humans - will generate a lot of interest in the element. In the study, 12 postmenopausal women consumed a very low boron diet (0.25 milligrams per day) for 17 weeks then were given a daily 3-mg supplement - representing the boron intake from a well-balanced diet - for 7 more weeks. Within 8 days after the supplement was introduced, the lost 40 percent less calcium, one-third less magnesium, and slightly less phosphorus through the urine. In fact, their calcium and magnesium losses were lower than prestudy levels, when they were on their normal diets. Since boron isn't considered essential for people, there is not recommended intake and no boron supplement on the market. Nielsen says the supplement of sodium borate used in the study was specially prepared based on the amount of boron a person would get from a well-balanced diet containing fruits and vegetables. He says the average boron intake is about 1.5 mg - or half the experimental dose - but average means a lot of people get less and a lot get more. Hunt cautioned that large doses of boron can be toxic, even lethal. The lowest reported lethal dose of boric acid is about 45 grams (1.6 ounces) for an adult and only 2 grams (0.07 ounce) for an infant.

  18. A 3D high resolution ex vivo white matter atlas of the common squirrel monkey (saimiri sciureus) based on diffusion tensor imaging (United States)

    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.

  19. 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. PMID:18521806

  20. Practical session assessments in human anatomy: Weightings and performance. (United States)

    McDonald, Aaron C; Chan, Siew-Pang; Schuijers, Johannes A


    Assessment weighting within a given module can be a motivating factor for students when deciding on their commitment level and time given to study a specific topic. In this study, an analysis of assessment performances of second year anatomy students was performed over four years to determine if (1) students performed better when a higher weighting was given to a set of practical session assessments and (2) whether an improved performance in the practical session assessments had a carry-over effect on other assessment tasks within that anatomy module and/or other anatomy modules that follow. Results showed that increasing the weighting of practical session assessments improved the average mark in that assessment and also improved the percentage of students passing that assessment. Further, it significantly improved performance in the written end-semester examination within the same module and had a carry-over effect on the anatomy module taught in the next teaching period, as students performed better in subsequent practical session assessments as well as subsequent end-semester examinations. It was concluded that the weighting of assessments had significant influences on a student's performance in that, and subsequent, assessments. It is postulated that practical session assessments, designed to develop deep learning skills in anatomy, improved efficacy in student performance in assessments undertaken in that and subsequent anatomy modules when the weighting of these assessments was greater. These deep learning skills were also transferable to other methods of assessing anatomy. Anat Sci Educ 9: 330-336. © 2015 American Association of Anatomists. PMID:26580309

  1. 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.

  2. An anatomy precourse enhances student learning in veterinary anatomy. (United States)

    McNulty, Margaret A; Stevens-Sparks, Cathryn; Taboada, Joseph; Daniel, Annie; Lazarus, Michelle D


    Veterinary anatomy is often a source of trepidation for many students. Currently professional veterinary programs, similar to medical curricula, within the United States have no admission requirements for anatomy as a prerequisite course. The purpose of the current study was to evaluate the impact of a week-long precourse in veterinary anatomy on both objective student performance and subjective student perceptions of the precourse educational methods. Incoming first year veterinary students in the Louisiana State University School of Veterinary Medicine professional curriculum were asked to participate in a free precourse before the start of the semester, covering the musculoskeletal structures of the canine thoracic limb. Students learned the material either via dissection only, instructor-led demonstrations only, or a combination of both techniques. Outcome measures included student performance on examinations throughout the first anatomy course of the professional curriculum as compared with those who did not participate in the precourse. This study found that those who participated in the precourse did significantly better on examinations within the professional anatomy course compared with those who did not participate. Notably, this significant improvement was also identified on the examination where both groups were exposed to the material for the first time together, indicating that exposure to a small portion of veterinary anatomy can impact learning of anatomical structures beyond the immediate scope of the material previously learned. Subjective data evaluation indicated that the precourse was well received and students preferred guided learning via demonstrations in addition to dissection as opposed to either method alone.

  3. The History of the Wolff–Parkinson–White Syndrome

    Directory of Open Access Journals (Sweden)

    Melvin M. Scheinman


    Full Text Available While Drs Wolff, Parkinson, and White fully described the syndrome in 1930, prior case reports had described the essentials. Over the ensuing century this syndrome has captivated the interest of anatomists, clinical cardiologists, and cardiac surgeons. Stanley Kent described lateral muscular connections over the atrioventricular (AV groove which he felt were the normal AV connections. The normal AV connections were, however, clearly described by His and Tawara. True right-sided AV connections were initially described by Wood et al., while Öhnell first described left free wall pathways. David Scherf is thought to be the first to describe our current understanding of the pathogenesis of the WPW syndrome in terms of a re-entrant circuit involving both the AV node–His axis as well as the accessory pathway. This hypothesis was not universally accepted, and many theories were applied to explain the clinical findings. The basics of our understanding were established by the brilliant work of Pick, Langendorf, and Katz who by using careful deductive analysis of ECGs were able to define the basic pathophysiological processes. Subsequently, Wellens and Durrer applied invasive electrical stimulation to the heart in order to confirm the pathophysiological processes. Sealy and his colleagues at Duke University Medical Center were the first to successfully surgically divide an accessory pathway and ushered in the modern era of therapy for these patients. Morady and Scheinman were the first to successfully ablate an accessory pathway (posteroseptal using high-energy direct-current shocks. Subsequently Jackman, Kuck, Morady, and a number of groups proved the remarkable safety and efficiency of catheter ablation for pathways in all locations using radiofrequency energy. More recently, Gollob et al. first described the gene responsible for a familial form of WPW. The current ability to cure patients with WPW is due to the splendid contributions of individuals

  4. 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 < 0.0001). This model of table 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.

  5. Plastination technology for anatomical studies in Nigeria: Opinion of teachers at medical institutions

    Directory of Open Access Journals (Sweden)

    Onyemaechi O. Azu


    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.

  6. [Sigismund Laskowski and his anatomical preparations technique]. (United States)

    Gryglewski, Ryszard W


    Fixation of the entire bodies or individual organs, and later as well tissues and cellular structures, was and still is often a challenge for anatomists and histologists. Technique that combines extensive knowledge of natural sciences, as well as technical skills, was by those best researchers as Frederik Ruysch, brought to perfection. Preparations, if done with care and talent, are really propelling progress in anatomical studies and determining the quality of education for medical students and young physicians. And as it is true for many of today's medical disciplines and natural sciences, the nineteenth century was in many ways a breaking point for preparatory techniques in the realm of anatomy and histology. Among those who have achieved success, earning notoriety during their lifetime and often going into the annals of European most distinguished scholars were some Polish names: Louis Maurice Hirschfeld, whose preparations of the nervous system earned him well-deserved, international fame, Louis Charles Teichmann, who was the very first so precisely describing the lymphatic system and a creator of unique injection mass, Henry Kadyi, known for his outstanding preparations, especially of vascular system. Henry Frederick Hoyer sen., who was one of the first to use formalin regularly for accurate microscopic preparations, is seen by many as the founder of the Polish histology. In this group of innovators and precursors of modern preparation techniques place should be reserved for Zygmunt (Sigismund) Laskowski, Polish patriot, fighting in January Uprising, later an immigrant, a professor at the university sequentially Paris and Geneva. Acclaimed author of anatomical tables and certainly creator of one of the groundbreaking techniques in anatomical preparations. Based after many years of research on the simple glycerine-phenol mixture achieved excellent results both in fixation of entire bodies and organs or tissues. Quality of those preparations was as high and

    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.

  8. 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.

  9. Revisiting a historic human brain with magnetic resonance imaging – the first description of a divided central sulcus

    Directory of Open Access Journals (Sweden)

    Renate eSchweizer


    Full Text Available In 1860 and 1862, the German physiologist Wagner published two studies, in which he compared the cortical surfaces of brain specimens. This provided the first account of a rare anatomical variation – bridges across the central sulci in both hemispheres connecting the forward and backward facing central convolutions in one of the brains. The serendipitous rediscovery of the preserved historic brain specimen in the collections at Göttingen University, being mistaken as the brain of the mathematician C.F. Gauss, allowed us to further investigate the morphology of the bridges Wagner had described with magnetic resonance imaging (MRI. On the historic lithograph, current photographs and MRI surface reconstructions of the brain, a connection across the central sulcus can only be seen in the left hemisphere. In the right hemisphere, contrary to the description of Wagner, a connecting structure is only present across the postcentral sulcus. MRI reveals that the left-hemispheric bridge extends into the depth of the sulcus, forming a transverse connection between the two opposing gyri. This rare anatomical variation, generally not associated with neurological symptoms, would nowadays be categorized as a divided central sulcus. The left-hemispheric connection seen across the postcentral sulcus, represents the very common case of a segmented postcentral sulcus. MRI further disclosed a connection across the right-hemispheric central sulcus, which terminates just below the surface of the brain and is therefore not depicted on the historical lithography. This explains the apparent inconsistency between the bilateral description of bridges across the central sulci and the unilateral appearance on the brain surface. The results are discussed based on the detailed knowledge of anatomists of the late 19th century, who already recognized the divided central sulcus as an extreme variation of a deep convolution within the central sulcus.

  10. Teaching the Anatomy of Oncology: Evaluating the Impact of a Dedicated Oncoanatomy Course

    International Nuclear Information System (INIS)

    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.

    Full Text Available OBJECTIVE: In our study, we aimed to reveal the data of the international scientific publications in the field of anatomy recorded in our country since 2000. MATERIALS AND METHODS: The data at the Turkey-based publications, which have at least one anatomy specialist identified and have been published in journals at the ISI Web of Science database and covered by the Science Citation Index (SCI and SCI-E (Expanded, were screened. The time period for the study was between the years 2000 and 2014. Number of publications by year, rate of increase in the number of publications, classification of broadcast (articles, papers, etc., category of publications, and their citation rates were recorded. We evaluated the top 10 journals which have the most comprising publications and the top 10 universities which facilitated these publications. RESULTS: Since 2000, we reached a total of 1390 publications in the field of anatomy. These publications comprised of 1273 original articles, 35 meeting presentations, 32 abstracts, 27 letters to the editor, and 23 compilations. With respect to the number of publications, there is a gradual decrease in recent years, despite a significant increase observed in the year 2009. In Turkey, the most published and cited categories are surgical anatomy, morphology, and neuroscience. The top three journals with the highest number of publications are Surgical and Radiologic Anatomy, Saudi Medical Journal, and Clinical Anatomy. The top three publishing institutions are Ankara University, Hacettepe University, and Ege University. CONCLUSION: Our study provides us an understanding of the topics anatomists have favored to study in recent years. A large number of published research articles are about surgical anatomy, morphology, and neuroscience. Obviously, the quality of publications and their number of citations are more important than their scalar quantity. We believe that future studies should focus on the multidisciplinary areas

    Full Text Available Introduction: The Carotid Canal is an important structure at the base of skull as it conveys the internal carotid artery, along with a sympathetic nerve plexus and a venous plexus. Previous researches done on carotid canal suggest that abnormalities to this canal, such as fractures of carotid canal and carotid sympathetic plexus schwannoma have their effect on the internal carotid artery and the structures passing through it. Cases of absence of carotid canal have also been reported, which causes variations of the internal carotid artery. Attempt has been made in this study to give a detailed view of the ‘external opening of carotid canal’ (EOCC which is the gateway of the carotid canal at the skull base. This study shall be useful for Surgeons, Radiologists, Anatomists, Forensic Experts, Anthropologists, etc. Aim: This study aims at measuring the various dimensions of the external openings of the carotid canal pair present at the base of skull, and to observe the age changes, sexual dimorphism, and symmetry of the external opening of the carotid canal from the analysis of these measurements. Materials and methods: Total 235 dry skulls that included 181 adolescent to adult skulls of known age and sex (age ranging from 13 years up to old age skulls of 60 years or above and 54 foetal skulls were studied for this purpose. The longest & shortest diameter of each carotid canal, was measured using a screw adjusted compass and a Vernier Calliper. Their distance from pharyngeal tubercle and from the X axis and Y axis was measured. Observations and Results: In the present study, it was observed that external opening of each carotid canal was unique in its morphology and morphometry. The dimensions of external opening of carotid canal progressively increased from foetal age to 25 years of age, however after 25 years of age, it did not show any age change within same sex, but it showed age changes when adolescent female skulls of age less than 25 years

  13. Historical perspective on developmental concepts and terminology. (United States)

    Opitz, John M; Neri, Giovanni


    In their ontogeny and phylogeny all living beings are historical entities. The revolution in biology of the 18th and 19th centuries that did away with the scala naturae according to which we humans, the acme of creation, "made a little lower than the angels," also led to the gradual realization that a humble one-celled protist ("protoctist"), such as Entamoeba histolytica of ill repute [Margulis and Chapman, ] has the same 4-billion-year phylogeny as that of Homo sapiens, vivid testimony to common ancestry and the relatedness of all living beings on earth. The group of medical geneticists who assembled at the NIH, Bethesda, MD this January to address terms pertaining to human ontogeny, did so in the long tradition of Sydenham, Linnaeus, Meckel, Geoffroy St-Hilaire père et fils, Wilhelm His and so many others before who had over the previous two centuries wrestled as earnestly as they could with concepts of "classification" and nomenclature of developmental anomalies. The prior massive need for classification per se in medical morphology has diminished over the years in favor of ever more sophisticated understanding of pathogenesis and cause through experimental biology and genetics; however, in the winter of 2013 it was still found prudent to respect terminological precedent on general terms while recognizing recent advances in developmental pathology requiring clarification and definition of special terms. Efforts along similar lines instigated by the German Society of Anatomists at their first meeting in Leipzig in 1887 culminated, after intense years of work by hundreds of experts and consultants under the goad of Wilhelm His, in the Basel Nomina Anatomica [BNA, His (1895)]. His, himself, stated prefatorily that the BNA had no legislative weight, only an evanescent consensus of many to be amended in the future as needed and indicated. Without hubris, no one before or after will do the same. The more substantial the consensus the more permanent the structure

    This paper presents a survey of the cell groups in the telencephalon of the teleost Astyanax hubbsi, based on series of transverse sections stained with the Nissl-Klüver-Barrera and Bodian procedures. The work was conducted for two reasons. Firstly, it was intended to determine the contribution of the forebrain of blind cave fish to certain forms of behavior. An understanding of the anatomy of the telencephalic organization is essential for such a neuroethological approach. The second purpose was to provide the cytoarchitectural basis for the experimental analysis of the fiber connectivity of the telencephalon of A. hubbsi. Furthermore, information about the forebrain of characids is widely lacking, and this study may thus provide important knowledge about the cellular organization of characid forebrains for comparative anatomists. The brain of A. hubbsi is slender and elongated. Both optic nerves and optic tectum are reduced. Three longitudinal sulci-s. ypsiliformis, s. externus and s. limitans telencephali-can be distinguished in the telencephalon. A fiber lamina reaching from the s. externus to the s. limitans telencephali separates the area dorsalis (D) from the area ventralis telencephali (V). The two hemispheres are connected by fibers decussating in the anterior commissure. Although cross sections revealed no distinct fiber laminae between cytoarchitectonic components, 17 cell masses could be delineated: ten of these belong to D, seven to V. The topological analysis yielded the following results. The dorsal telencephalon D consists of three longitudinal columns, termed pars medialis (Dm), pars dorsalis and centralis (Dd and Dc) considered together, and par lateralis (Dl), which converge into a uniform posterior part (Dp). The columns can be divided into several subregions: Dm1 and Dm2, as well as Dlv and Dld, precommissurally, Dm3 and Dm4 postcommisurally. At polus posterior levels nucleus tenia can be identified. The ventral telencephalon (V) is arranged

  16. [Woman and race biology]. (United States)

    Hanson, H


    Early 20th century race biology takes a special interest in woman as part of the "intra-racial" project of bringing forth healthy and competitive individuals. But there are other motives as well for the race biologist to take an interest in woman. She is believed to develop fewer individual characteristics and is therefore a more typical representative of her race than man. The development level of the race is also presupposed to be discernible by the degree of "gender diformism": a race of higher standing would exhibit a greater difference between the sexes. The anthropologist, anatomist, gynaecologist--or whatever guise the race biologist may adopt-- will, in principle, stress that the relation between the sexes is not a matter of "more or less", but one of differences in kind. In reality, the "more-or-less of comparison is the very cornerstone of the issue. Quantitative differences, directly observed or obtained from statistics, are construed as signs of difference in kind. 18th century medical philosophy and sex-linked anthropology laid the theoretical foundation of the 19th century essentialist conception of woman, which is also that adopted by race biology. Eugenics of social Darwinist inspiration regarded prophylactic health care and social welfare programs with scepticism. A race biology founded on the man-woman dualism could sustain altogether different conclusions. An advanced culture calls for extensive division of labour. An extended childhood renders possible higher development but will also impose higher demands on woman. The protection of the female organism is thus an exigency for any people or race striving to survive and evolve. From society's care for the female organism health care for women and preventive maternity care will emerge. Race biology has been a preeminently German concern, as indicated by the selection of works taken to represent this perspective on woman: Bartels-Ploss' Das Weib, C.H. Stratz' Die Rassenschönheit des Weibes and

    Full Text Available The principal arteries of the upper limb show a wide range of variation that is of considerable interest to orthopedic surgeons, plastic surgeons, radiologists and anatomists. We present here a case of superficial ulnar artery found during the routine dissection of right upper limb of a 50-year-old male cadaver. The superficial ulnar artery originated from the brachial artery, crossed the median nerve anteriorly and ran lateral to this nerve and the brachial artery. The superficial ulnar artery in the arm gave rise to a narrow muscular branch to the biceps brachii. At the elbow level the artery ran superficial to the bicipital aponeurosis where it was crossed by the median cubital vein. It then ran downward and medially superficial to the forearm flexor muscles, and then downward to enter the hand. At the palm, it formed the superficial and deep palmar arches together with the branches of the radial artery. The presence of a superficial ulnar artery is clinically important when raising forearm flaps in reconstructive surgery. The embryology and clinical significance of the variation are discussed.As principais artérias do membro superior apresentam uma ampla variação, que é relativamente importante a cirurgiões ortopédicos e plásticos, radiologistas e anatomistas.Apresentamosumcaso de artéria ulnar superficial encontrada durante dissecção de rotina de membro superior direito de um cadáver masculino de 50 anos de idade.Aartéria ulnar superficial originava-se da artéria braquial, cruzava o nervo mediano anteriormente e percorria lateralmente esse nervo e a artéria braquial. A artéria ulnar superficial no braço deu origem a um ramo muscular estreito do músculo bíceps braquial. Ao nível do cotovelo, a artéria percorria superficialmente a aponeurose bicipital, onde era cruzada pela veia cubital mediana. Percorria, então, em sentido descendente e medialmente superficial aos músculos flexores do antebraço, e então descendia para

  18. Genotoxic damage in pathology anatomy laboratory workers exposed to formaldehyde

    International Nuclear Information System (INIS)

    Formaldehyde (FA) is a chemical traditionally used in pathology and anatomy laboratories as a tissue preservative. Several epidemiological studies of occupational exposure to FA have indicated an increased risk of nasopharyngeal cancers in industrial workers, embalmers and pathology anatomists. There is also a clear evidence of nasal squamous cell carcinomas from inhalation studies in the rat. The postulated mode of action for nasal tumours in rats was considered biologically plausible and considered likely to be relevant to humans. Based on the available data IARC, the International Agency for Research on Cancer, has recently classified FA as a human carcinogen. Although the in vitro genotoxic as well as the in vivo carcinogenic potentials of FA are well documented in mammalian cells and in rodents, evidence for genotoxic effects and carcinogenic properties in humans is insufficient and conflicting thus remains to be more documented. To evaluate the genetic effects of long-term occupational exposure to FA a group of 30 Pathological Anatomy laboratory workers was tested for a variety of biological endpoints, cytogenetic tests (micronuclei, MN; sister chromatid exchange, SCE) and comet assay. The level of exposure to FA was evaluated near the breathing zone of workers, time weighted average of exposure was calculated for each subject. The association between the biomarkers and polymorphic genes of xenobiotic metabolising and DNA repair enzymes was also assessed. The mean level of exposure was 0.44 ± 0.08 ppm (0.04-1.58 ppm). MN frequency was significantly higher (p = 0.003) in the exposed subjects (5.47 ± 0.76) when compared with controls (3.27 ± 0.69). SCE mean value was significantly higher (p < 0.05) among the exposed group (6.13 ± 0.29) compared with control group (4.49 ± 0.16). Comet assay data showed a significant increase (p < 0.05) of TL in FA-exposed workers (60.00 ± 2.31) with respect to the control group (41.85 ± 1.97). A positive correlation was

  19. Visualization of the segment IV hepatic artery using 128-section MDCT angiography

    International Nuclear Information System (INIS)

    Aim: To visualize the segment IV hepatic artery and to evaluate the variations in anatomy using multidetector computed tomography (MDCT) angiography. Materials and methods: Six hundred and seventeen patients (381 men and 236 women; mean age 62.7 ± 8.1 years; age range 22–92 years) who underwent MDCT angiography performed using a 128-section MDCT system were included in the study. The segment IV hepatic arteries of 453 patients with adequate image quality were displayed using volume rendering (VR), maximum intensity projection (MIP), and multiplanar reconstruction (MPR), and were analysed regarding the origination and variation of the arteries by two radiologists and an anatomist retrospectively. Results: Segment IV arteries were categorized into five different types according to their points of origin: left hepatic artery (LHA, 51.66%), right hepatic artery (RHA, 30.68%), proper hepatic artery (PHA, 5.3%), dual (12.14%), and triple (0.22%). Segment IV arteries arising from normal LHA, RHA, and PHA were found in 73.73% of patients, and those arising from variant LHA or RHA were found in 26.27%. The patterns RN2, LA2, LA3, LA4, PN2, PV1, DA1, DA2, DV3, and DV4 were first reported in the present study. Conclusions: MDCT angiography can evaluate normal as well as anatomical variants of segment IV arteries. Predicting arterial patterns of segment IV of the liver is important in planning and performing all radiological and surgical procedures in the liver, especially in hemi-liver graft procedures. - Highlights: • Segment IV artery was evaluate and mapped by using MDCT angiography. • Segment IV arteries were categorized into five different types: RHA, LHA, PHA, Dual, and Triple. • The patterns of RN2, LA2, LA3, LA4, DA1, DA2, DN4, DV3 and DV4 were first reported. • Predicting arterial patterns of segment IV is helpful for segmental hepatectomy, LDLT, SLT, and TACE

  20. On the history of deformation phosphenes and the idea of internal light generated in the eye for the purpose of vision. (United States)

    Grüsser, O J; Hagner, M


    Deformation phosphenes are light sensations evoked by deformation of the eyeball in total darkness. They were first reported in Western literature by Alcmaeon of Croton in the fifth century B.C. The phenomenon of deformation phosphenes was instrumental in prompting some pre-Socratic philosophers and Plato to conceive the idea that efferent light is emitted from the eye for the purpose of vision and a 'cone of vision' is formed by interaction with the external light. In the theories of vision this cone of vision played an important role as a signal-transmitting structure and was also used by the Greek opticians as a geometrical construction to explain optical properties of vision. The impact of the deformation phosphene experiment on the ideas of visual sensation can be followed from Greek antiquity through the period of Roman dominance and Galen's medical teaching on to medieval times and up to the late Renaissance when, based on the anatomy of the eye as illustrated by Felix Platter, the image formation on the retina was correctly described for the first time by Johannes Kepler. In the generations following, deformation phosphenes were still employed as an important argument in defence of the theories of vision. However, the idea of physical light generated by eyeball deformation was rejected with increasing frequency during the 17th and 18th centuries. The literature on this topic is discussed, comprising the contributions of the Arabic philosophers and physicians of the 9th and 10th centuries A.D., the Franciscan and Dominican philosophers of the 13th century, Nicolaus Cusanus of the 15th century, several anatomists of the 16th and 17th centuries, Kepler, Plempius, Descartes, Boyle, Newton and others. After Kepler, the mechanical interpretation of the deformation phosphene being caused by direct action of the eyeball deformation onto the retina slowly became dominant, and the idea that physical light is generated in the eye disappeared.

    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

    Full Text Available ABSTRACT: Context (Background: Many authors have studied sutural bones in various parts of the world. Examples of such work done in the Eastern Region of I ndia are not known to many in the medical community. Therefore, the authors have endeavored to give some insight into the topic and compile a baseline data of such traits by studying the incidence and distribution of various types of sutural bones in the E astern region of India. AIMS : To study the incidence and distribution of various types of sutural bones in the Eastern region of India with particular attention to sex distribution. SETTINGS AND DESIGN : A cross - sectional observational study was conducted b ased on dry adult crania in the muse um of Department of Anatomy over a period of 1 year. METHODS AND MATERIAL: 111 dry adult crania were selected as per inclusion and exclusion criteria. The number of crania with sutural bones in each sex, the total number of sutural bones in each sex and the distribution of sutural bones present bilaterally and in the midline in both males and females were studied. STATISTICAL ANALYSIS : Z - Test was performed for the distribution of sutural bones. A p - value <0.05 was consid ered significant. The results were calculated using Epi Info TM statistical software (version 3.4.1 July 3, 2007 for Windows. RESULTS : The gross incidence of sutural bones was 69.37%. The gross percentages of males and females with sutural bones were 38.74 and 30.63 respectively. Higher number of sutural bones were observed in females (188 compared to males (153. There was a statistically significant difference in the distribution of LO type of sutural bone present bilaterally between male and female cran ia. CONCLUSION: Minor variations in the ossicles of the cranium have aroused the curiosity of anatomists for many decades. Studies have shown that the presence of sutural bones is associated with other cranial and central nervous system abnormalities. The presence of sutural

    with various radiological modalities. CONCLUSION: Liver is a complicated organ. Naming of the parts of this complex inner organ is still highly varied: parts, halves, lobes, divisions, sectors, segments, and sub-segments. Our understanding and explanation of liver composition are still defined differently among anatomists, surgeons, and radiologists, thus not only confusing less experienced specialists, but also increasing probability of mistakes. Such a lack of communication aggravates the design of an operation plan and its documentation, which frequently may even result in undesirable legal consequences.

  5. Concept and treatment of hydrocephalus in the Greco-Roman and early Arabic medicine. (United States)

    Grunert, P; Charalampaki, P; Ayyad, A


    . The surgery consisted in one or more incisions and evacuation of the fluid. The wound was not closed but let open for three days. Thereafter plasters or sutures closed the incisions. The surgical technique goes back probably to Antyllos a surgeon from the 3rd century AD whose considerations were cited in the work of Oreibasios. The early Arabic physicians took over the surgical indications, the operative technique and modified the Greek concept of hydrocephalus. Avicenna separated the traumatic haematomas outside the skull from the term hydrocephalus. However Avicenna, as all previous authors, had not linked hydrocephalus with the ventricular system. The autopsy of a child with an exorbitant hydrocephalus performed by the anatomist Vesalius in the 16th century revealed as a single pathology an extremely dilative ventricular system filled with water-like fluid which made it necessary to change completely the ancient concept of hydrocephalus.
