    Animal anatomy has traditionally relied on detailed dissections to produce anatomical illustrations, but modern imaging modalities, such as MRI and CT, now represent an enormous resource that allows for fast non-invasive visualizations of animal anatomy in living animals. These modalities also allow for creation of three-dimensional representations that can be of considerable value in the dissemination of anatomical studies. In this methodological review, we present our experiences using MRI, CT and μCT to create advanced representation of animal anatomy, including bones, inner organs and blood vessels in a variety of animals, including fish, amphibians, reptiles, mammals, and spiders. The images have a similar quality to most traditional anatomical drawings and are presented together with interactive movies of the anatomical structures, where the object can be viewed from different angles. Given that clinical scanners found in the majority of larger hospitals are fully suitable for these purposes, we encourage biologists to take advantage of these imaging techniques in creation of three-dimensional graphical representations of internal structures.

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

    Animal models have been commonly used for in vivo and in vitro spinal research. However, the extent to which animal models resemble the human spine has not been well known. We conducted a systematic review to compare the morphometric features of vertebrae between human and animal species, so as to give some suggestions on how to choose an appropriate animal model in spine research. A literature search of all English language peer-reviewed publications was conducted using PubMed, OVID, Springer and Elsevier (Science Direct) for the years 1980-2008. Two reviewers extracted data on the anatomy of large animal spines from the identified articles. Each anatomical study of animals had to include at least three vertebral levels. The anatomical data from all animal studies were compared with the existing data of the human spine in the literature. Of the papers retrieved, seven were included in the review. The animals in the studies involved baboon, sheep, porcine, calf and deer. Distinct anatomical differences of vertebrae were found between the human and each large animal spine. In cervical region, spines of the baboon and human are more similar as compared to other animals. In thoracic and lumbar regions, the mean pedicle height of all animals was greater than the human pedicles. There was similar mean pedicle width between animal and the human specimens, except in thoracic segments of sheep. The human spinal canal was wider and deeper in the anteroposterior plane than any of the animals. The mean human vertebral body width and depth were greater than that of the animals except in upper thoracic segments of the deer. However, the mean vertebral body height was lower than that of all animals. This paper provides a comprehensive review to compare vertebrae geometries of experimental animal models to the human vertebrae, and will help for choosing animal model in vivo and in vitro spine research. When the animal selected for spine research, the structural similarities and

    2016-01-01

    In this paper, I examine the procedures used by Andreas Vesalius for conducting public dissections in the early sixteenth century. I point out that in order to overcome the limitations of public anatomical demonstration noted by his predecessors, Vesalius employed several innovative strategies, including the use of animals as dissection subjects, the preparation and display of articulated skeletons, and the use of printed and hand-drawn illustrations. I suggest that the examination of these three strategies for resolving the challenges of public anatomical demonstration helps us to reinterpret Vesalius's contributions to sixteenth-century anatomy. © The Author 2015.

    To develop a noninvasive technique to assess liver volumetry and intrahepatic portal vein anatomy in a mouse model of liver regeneration. Fifty-two C57BL/6 male mice underwent magnetic resonance imaging (MRI) of the liver using a 4.7 T small animal MRI system after no treatment, 70% partial hepatectomy (PH), or selective portal vein embolization. The protocol consisted of the following sequences: three-dimensional-encoded spoiled gradient-echo sequence (repetition time per echo time 15 per 2.7 ms, flip angle 20°) for volumetry, and two-dimensional-encoded time-of-flight angiography sequence (repetition time per echo time 18 per 6.4 ms, flip angle 80°) for vessel visualization. Liver volume and portal vein segmentation was performed using a dedicated postprocessing software. In animals with portal vein embolization, portography served as reference standard. True liver volume was measured after sacrificing the animals. Measurements were carried out by two independent observers with subsequent analysis by the Cohen κ-test for interobserver agreement. MRI liver volumetry highly correlated with the true liver volume measurement using a conventional method in both the untreated liver and the liver remnant after 70% PH with a high interobserver correlation coefficient of 0.94 (95% confidence interval, 0.80-0.98 for untreated liver [P anatomy was excellent (Cohen κ value = 0.925). This protocol may be used for noninvasive liver volumetry and visualization of portal vein anatomy in mice. It will serve the dynamic study of new strategies to enhance liver regeneration in vivo.

  12. Comparison of gross anatomy test scores using traditional specimens vs. QuickTime Virtual Reality animated specimens

    In recent years, technological advances such as computers have been employed in teaching gross anatomy at all levels of education, even in professional schools such as medical and veterinary medical colleges. Benefits of computer based instructional tools for gross anatomy include the convenience of not having to physically view or dissect a cadaver. Anatomy educators debate over the advantages versus the disadvantages of computer based resources for gross anatomy instruction. Many studies, case reports, and editorials argue for the increased use of computer based anatomy educational tools, while others discuss the necessity of dissection for various reasons important in learning anatomy, such as a three-dimensional physical view of the specimen, physical handling of tissues, interactions with fellow students during dissection, and differences between specific specimens. While many articles deal with gross anatomy education using computers, there seems to be a lack of studies investigating the use of computer based resources as an assessment tool for gross anatomy, specifically using the Apple application QuickTime Virtual Reality (QTVR). This study investigated the use of QTVR movie modules to assess if using computer based QTVR movie module assessments were equal in quality to actual physical specimen examinations. A gross anatomy course in the College of Veterinary Medicine at Cornell University was used as a source of anatomy students and gross anatomy examinations. Two groups were compared, one group taking gross anatomy examinations in a traditional manner, by viewing actual physical specimens and answering questions based on those specimens. The other group took the same examinations using the same specimens, but the specimens were viewed as simulated three-dimensional objects in a QTVR movie module. Sample group means for the assessments were compared. A survey was also administered asking students' perceptions of quality and user-friendliness of the QTVR

    Natural collagen is easily available from animal tissues such as bones. Main limitations reported in the use of natural collagen are heterogeneity and loss of integrity during recovery. However, its natural complexity, functionality and bioactivity still remain to be achieved through synthetic and recombinant ways. Variability of physicochemical properties of collagen extracted from bovine bone by acetic acid was then investigated taking into account endogenous and exogenous factors. Endogenous: bovine's bones age (4 and 7 years) and anatomy (femur and tibia); exogenous: thermal treatments (spray-drying and lyophilisation). Scanning electron microscopy, spectroscopy (EDS, FTIR, UV/Vis and CD), differential scanning calorimetry (DSC), centesimal composition, mass spectrometry, amino acids and zeta-potential analysis were used for the purpose. Age correlated negatively with yield of recovery and positively with minerals and proteoglycans content. Comparing the anatomy, higher yields were found for tibias, and higher stability of tibias collagen in solution was noticed. Whatever the age and the anatomy, collagens were able to renature and to self-assemble into tri-dimensional structures. Nonetheless thermal stability and kinetics of renaturation were different. Variability of natural collagen with bone age and anatomy, and drying methodology, may be a crucial advantage to conceive tailor-made applications in either the biological or technical sector.

    The title integer anatomy is intended to convey the idea of a systematic method for displaying the prime decomposition of the integers. Just as the biological study of anatomy does not teach us all things about behavior of species neither would we expect to learn everything about the number theory from a study of its anatomy. But, some number-theoretic theorems are illustrated by inspection of integer anatomy, which tend to validate the underlying structure and the form as developed and displayed in this treatise. The first statement to be made in this development is: the way structure of the natural numbers is displayed depends upon the allowed operations.

    The radionuclides of most concern with respect to contamination of animals after a nuclear accident are radioiodine, radiocaesium and radiostrontium (ICRP 30, 1979). Of the other significant anthropogenic radionuclides likely to be released in most accidents, only small proportions of that ingested will be absorbed in an animals gut, and the main animal products, milk and meat, will not normally be contaminated to a significant extent. Animal products will mostly be contaminated as a result of ingestion of contaminated feed and possibly, but to a much lesser extent, from inhalation (for radioiodine only). Direct external contamination of animals is of little or no consequence in human food production. Radioiodine and radiostrontium are important with respect to contamination of milk; radiocaesium contaminates both milk and meat. The physical and chemical form of a radionuclide can influence its absorption in the animal gut. For example, following the Chernobyl accident radiocaesium incorporated into vegetation by root uptake was more readily absorbed than that associated with the original deposit. The transfer of radiocaesium and radiostrontium to animals will be presented both as transfer coefficients and aggregated transfer coefficients. For most animal meat products, only radiocaesium is important as other radionuclides do not significantly contaminate muscle. Farm animal products are the most important foodstuff determining radiocaesium intake by the average consumer in the Nordic countries. The major potential source of radioiodine and radiostrontium to humans is milk and milk products. Of the different species, the smaller animals have the highest transfer of radiocaesium from fodder to meat and milk. (EG)

    The familiar extremes of crystalline material are single-crystals and random powders. In between these two extremes are polycrystalline aggregates, not randomly arranged but possessing some preferred orientation and this is the form taken by constructional materials, be they steel girders or the bones of a human or animal skeleton. The details of the preferred orientation determine the ability of the material to withstand stress in any direction. In the case of bone the crucial factor is the orientation of the c-axes of the mineral content - the crystals of the hexagonal hydroxyapatite - and this can readily be determined by neutron diffraction. In particular it can be measured over the volume of a piece of bone, utilizing distances ranging from 1mm to 10mm. The major practical problem is to avoid the intense incoherent scattering from the hydrogen in the accompanying collagen; this can best be achieved by heat-treatment and it is demonstrated that this does not affect the underlying apatite. These studies of bone give leading anatomical information on the life and activities of humans and animals - including, for example, the life history of the human femur, the locomotion of sheep, the fracture of the legs of racehorses and the life-styles of Neolithic tribes. We conclude that the material is placed economically in the bone to withstand the expected stresses of life and the environment. The experimental results are presented in terms of the magnitude of the 0002 apatite reflection. It so happens that for a random powder the 0002, 1121 reflections, which are neighboring lines in the powder pattern, are approximately equal in intensity. The latter reflection, being of manifold multiplicity, is scarcely affected by preferred orientation so that the numerical value of the 0002/1121 ratio serves quite accurately as a quantitative measure of the degree of orientation of the c-axes in any chosen direction for a sample of bone

    Gross anatomy is considered one of the most important basic science courses in medical education, yet few medical schools require its completion prior to matriculation. The effect of taking anatomy courses before entering medical school on performance in medical gross anatomy has been previously studied with inconsistent results. The effect of premedical anatomy coursework on performance in medical gross anatomy, overall medical school grade point average (GPA), and Comprehensive Osteopathic Medical Licensing Examination Level 1 (COMLEX 1) score was evaluated in 456 first-year osteopathic medical students along with a survey on its perceived benefits on success in medical gross anatomy course. No significant differences were found in gross anatomy grade, GPA, or COMLEX 1 score between students with premedical anatomy coursework and those without. However, significant differences and higher scores were observed in students who had taken three or more undergraduate anatomy courses including at least one with cadaveric laboratory. There was significantly lower perceived benefit for academic success in the medical gross anatomy course (Pstudents who had taken premedical anatomy courses (5.9 of 10) compared with those who had not (8.2 of 10). Results suggest that requiring any anatomy course as a prerequisite for medical school would not have significant effect on student performance in the medical gross anatomy course. However, requiring more specific anatomy coursework including taking three or more undergraduate anatomy courses, one with cadaveric laboratory component, may result in higher medical gross anatomy grades, medical school GPA, and COMLEX 1 scores.

    2016-02-01

    The anatomy of the skull base is complex with multiple neurovascular structures in a small space. Understanding all of the intricate relationships begins with understanding the anatomy of the sphenoid bone. The cavernous sinus contains the carotid artery and some of its branches; cranial nerves III, IV, VI, and V1; and transmits venous blood from multiple sources. The anterior skull base extends to the frontal sinus and is important to understand for sinus surgery and sinonasal malignancies. The clivus protects the brainstem and posterior cranial fossa. A thorough appreciation of the anatomy of these various areas allows for endoscopic endonasal approaches to the skull base. Copyright © 2016 Elsevier Inc. All rights reserved.

    2005-07-01

    The study of anatomy is important to accomplish any kind of surgical and medical procedure and to understand the physiology and diseases of animals. It is no different in veterinary dentistry. The study of oral anatomy helps the veterinarian to accomplish any kind of surgical procedure more quickly and with less damage to tissues, especially in cases of major oral surgery. In fact, under-standing the anatomy is easier when this knowledge is acquired directly, with surgical application. This article describes the essentials of the oral anatomy of the dog and cat, correlating this knowledge with the dental procedures to be used by veterinarians as a guide.

  1. Authenticity in Anatomy Art.

    Science.gov (United States)

    Adkins, Jessica

    2017-01-12

    The aim of this paper is to observe the evolution and evaluate the 'realness' and authenticity in Anatomy Art, an art form I define as one which incorporates accurate anatomical representations of the human body with artistic expression. I examine the art of 17th century wax anatomical models, the preservations of Frederik Ruysch, and Gunther von Hagens' Body Worlds plastinates, giving consideration to authenticity of both body and art. I give extra consideration to the works of Body Worlds since the exhibit creator believes he has created anatomical specimens with more educational value and bodily authenticity than ever before. Ultimately, I argue that von Hagens fails to offer Anatomy Art 'real human bodies,' and that the lack of bodily authenticity of his plastinates results in his creations being less pedagogic than he claims.

    2011-03-01

    In this article, the development of the female breast, as well as the functional anatomy, blood supply, innervation and lymphatic drainage are described. A thorough understanding of the breast anatomy is an important adjunct to a meticulous clinical breast examination. Breast examination is a complex skill involving key maneuvers, including careful inspection and palpation. Clinical breast examination can provide an opportunity for the clinician to educate patients about their breast and about breast cancer, its symptoms, risk factors, early detection, and normal breast composition, and specifically variability. Clinical breast examination can help to detect some cancers not found by mammography, and clinicians should not override their examination findings if imaging is not supportive of the physical findings.

    This study was designed to assess the grades, self-perceived learning, and satisfaction between occupational therapy students who used a gross anatomy laboratory versus online anatomy software (AnatomyTV) as tools to learn anatomy at a large public university and a satellite campus in the mid-western United States. The goal was to determine if equivalent learning outcomes could be achieved regardless of learning tool used. In addition, it was important to determine why students chose the gross anatomy laboratory over online AnatomyTV. A two group, post-test only design was used with data gathered at the end of the course. Primary outcomes were students' grades, self-perceived learning, and satisfaction. In addition, a survey was used to collect descriptive data. One cadaver prosection was available for every four students in the gross anatomy laboratory. AnatomyTV was available online through the university library. At the conclusion of the course, the gross anatomy laboratory group had significantly higher grade percentage, self-perceived learning, and satisfaction than the AnatomyTV group. However, the practical significance of the difference is debatable. The significantly greater time spent in gross anatomy laboratory during the laboratory portion of the course may have affected the study outcomes. In addition, some students may find the difference in (B+) versus (A-) grade as not practically significant. Further research needs to be conducted to identify what specific anatomy teaching resources are most effective beyond prosection for students without access to a gross anatomy laboratory. © 2015 American Association of Anatomists.

    The Japanese quail is a widely used model organism for the study of embryonic development; however, anatomical resources are lacking. The Quail Anatomy Portal (QAP) provides 22 detailed three-dimensional (3D) models of quail embryos during development from embryonic day (E)1 to E15 generated using optical projection tomography. The 3D models provided can be virtually sectioned to investigate anatomy. Furthermore, using the 3D nature of the models, we have generated a tool to assist in the staging of quail samples. Volume renderings of each stage are provided and can be rotated to allow visualization from multiple angles allowing easy comparison of features both between stages in the database and between images or samples in the laboratory. The use of JavaScript, PHP and HTML ensure the database is accessible to users across different operating systems, including mobile devices, facilitating its use in the laboratory.The QAP provides a unique resource for researchers using the quail model. The ability to virtually section anatomical models throughout development provides the opportunity for researchers to virtually dissect the quail and also provides a valuable tool for the education of students and researchers new to the field.

    Coraline D. Metzger

    2013-05-01

    Full Text Available The thalamus, a crucial node in the well-described cortico-striatal-thalamo-cortical circuits, has been the focus of functional and structural imaging studies investigating human emotion, cognition and memory. Invasive work in animals and post-mortem investigations have revealed the rich cytoarchitectonics and functional specificity of the thalamus. Given current restrictions in the spatial resolution of non-invasive imaging modalities, there is, however, a translational gap between functional and structural information on these circuits in humans and animals as well as between histological and cellular evidence and their relationship to psychological functioning.With the advance of higher field strengths for MR approaches, better spatial resolution is now available promising to overcome this conceptual problem.We here review these two levels, which exist for both neuroscientific and clinical investigations, and then focus on current attempts to overcome conceptual boundaries of these observations with the help of high-resolution imaging.

    Just after WWII Astronomy started to live its "Golden Age", not differently to many other sciences and human activities, especially in the west side countries. The improved resolution of telescopes and the appearance of new efficient light detectors (e.g. CCDs in the middle eighty) greatly impacted the extragalactic researches. The first morphological analysis of galaxies were rapidly substituted by "anatomic" studies of their structural components, star and gas content, and in general by detailed investigations of their properties. As for the human anatomy, where the final goal was that of understanding the functionality of the organs that are essential for the life of the body, galaxies were dissected to discover their basic structural components and ultimately the mystery of their existence.

    2017-12-01

    This paper presents the Generative Anatomy Modeling Language (GAML) for generating variation of 3D virtual human anatomy in real-time. This framework provides a set of operators for modification of a reference base 3D anatomy. The perturbation of the 3D models is satisfied with nonlinear geometry constraints to create an authentic human anatomy. GAML was used to create 3D difficult anatomical scenarios for virtual simulation of airway management techniques such as Endotracheal Intubation (ETI) and Cricothyroidotomy (CCT). Difficult scenarios for each technique were defined and the model variations procedurally created with GAML. This study presents details of the GAML design, set of operators, types of constraints. Cases of CCT and ETI difficulty were generated and confirmed by expert surgeons. Execution performance pertaining to an increasing complexity of constraints using nonlinear programming was in real-time execution. Copyright © 2017 John Wiley & Sons, Ltd.

  2. Penile Embryology and Anatomy

    Directory of Open Access Journals (Sweden)

    Jenny H. Yiee

    2010-01-01

    Full Text Available Knowledge of penile embryology and anatomy is essential to any pediatric urologist in order to fully understand and treat congenital anomalies. Sex differentiation of the external genitalia occurs between the 7thand 17th weeks of gestation. The Y chromosome initiates male differentiation through the SRY gene, which triggers testicular development. Under the influence of androgens produced by the testes, external genitalia then develop into the penis and scrotum. Dorsal nerves supply penile skin sensation and lie within Buck's fascia. These nerves are notably absent at the 12 o'clock position. Perineal nerves supply skin sensation to the ventral shaft skin and frenulum. Cavernosal nerves lie within the corpora cavernosa and are responsible for sexual function. Paired cavernosal, dorsal, and bulbourethral arteries have extensive anastomotic connections. During erection, the cavernosal artery causes engorgement of the cavernosa, while the deep dorsal artery leads to glans enlargement. The majority of venous drainage occurs through a single, deep dorsal vein into which multiple emissary veins from the corpora and circumflex veins from the spongiosum drain. The corpora cavernosa and spongiosum are all made of spongy erectile tissue. Buck's fascia circumferentially envelops all three structures, splitting into two leaves ventrally at the spongiosum. The male urethra is composed of six parts: bladder neck, prostatic, membranous, bulbous, penile, and fossa navicularis. The urethra receives its blood supply from both proximal and distal directions.

    The red panda ( Ailurus fulgens ) is classified as an endangered species by the International Union for Conservation of Nature and Natural Resources. The natural distribution of the red panda is in the Himalayas and southern China. Thoracic diseases such as dirofilariasis, hypertrophic cardiomyopathy, tracheal obstruction, lung worm infestation, and pneumonia have been reported in the red panda. The aim of this study was to describe the normal radiographic thoracic anatomy of captive red pandas as a species-specific reference for routine health examinations and clinical cases. Right lateral (RL) and dorsoventral (DV) inspiratory phase views of the thorax were obtained in 11 adult captive red pandas. Measurements were made and ratios calculated to establish reference ranges for the mean vertebral heart score on the RL (8.34 ± 0.25) and DV (8.78 ± 0.34) views and the mean ratios of the caudal vena cava diameter to the vertebral body length above tracheal bifurcation (0.67 ± 0.05) and tracheal diameter to the width of the third rib (2.75 ± 0.24). The majority of animals (10/11) had 14 thoracic vertebrae, except for one animal that had 15 thoracic vertebrae. Rudimentary clavicles were seen in 3/11 animals. The ovoid, oblique cardiac silhouette was more horizontally positioned and elongated in older animals. A redundant aortic arch was seen in the oldest animal. The trachea was seen with mineralized cartilage rings in all animals. The carina was clearly seen in the majority of animals (10/11). Variations exist in the normal radiographic thoracic anatomy of different species. Knowledge of the normal radiographic thoracic anatomy of the red panda should prove useful for routine health examinations and in the diagnosis of thoracic diseases.

    Victor Papilian was born an artist, during high school he studied music in order to become a violinist in two professional orchestras in Bucharest. Later on he enrolled in the school of medicine, being immediately attracted by anatomy. After graduating, with a briliant dissertation, he became a member of the faculty and continued to teach in his preferred field. His masters, Gh. Marinescu and Victor Babes, proposed him for the position of professor at the newly established Faculty of Medicine of Cluj. Here he reorganized the department radically, created an anatomy museum and edited the first dissection handbook and the first Romanian anatomy (descriptive and topographic) treatise, both books received with great appreciation. He received the Romanian Academy Prize. His knowledge and skills gained him a well deserved reputation and he created a prestigious school of anatomy. He published over 250 scientific papers in national and international journals, ranging from morphology to functional, pathological and anthropological topics. He founded the Society of Anthropology, with its own newsletter; he was elected as a member of the French Society of Anatomy. In parallel he had a rich artistic and cultural activity as writer and playwright: he was president of the Transylvanian Writers' Society, editor of a literary review, director of the Cluj theater and opera, leader of a book club and founder of a symphony orchestra.

    The rabbit is the primary animal model used to investigate aspects of nasal surgery. Although several studies have used this model, none has provided a comprehensive analysis of the surgical anatomy and techniques used to gain access to the rabbit nasal fossae and septum. To describe and optimize the surgical anatomy and approach to the rabbit nasal vault and septal cartilage. In an ex vivo animal study conducted at an academic medical center, preliminary cadaveric dissections were performed on rabbit head specimens to establish familiarity with relevant anatomy and rehearse various approaches. Live Pasteurella-free New Zealand white rabbits (3.5-4.0 kg) were used to further develop this surgical technique developed here. Access of the nasal vault was gained through a midline nasal dorsum incision and creation of an osteoplastic flap with a drill. Submucosal resection was performed with preservation of the mucoperichondrium. All rabbits were monitored daily for 4 weeks in the postoperative period for signs of infection, pain, and complications. The study was conducted from June 1, 2014, to December 1, 2014. Surgical anatomy and techniques used to gain access to the rabbit nasal vault and harvest septal cartilage. Four Pasteurella-free New Zealand white rabbits (Western Organ Rabbit Co), ranging in age from 9 to 12 months and weighing between 3.5 and 4.0 kg, were used in this study. Initial dissections demonstrated the feasibility of harvesting septal cartilage while preserving the mucoperichondrial envelope. Access to the nasal vault through this 3-osteotomy approach allowed for maximal exposure to the nasal cavity bilaterally while maintaining the integrity of the mucoperichondrium following septal cartilage harvest. The maximum amount of bulk, en bloc, cartilage harvested was 1.0 × 2.5 cm. Following surgical dissection, all animals maintained adequate airway patency and support to midface structures. Furthermore, all specimens preserved the integrity of the

    2009-07-01

    Students of cerebrovascular anatomy and physiology tend to model their learning based on normal patterns of blood flow. As such, the focus tends toward arterial physiology and pathology with less than adequate understanding of the significance of the venous system. This article presents a different approach to neurovascular anatomy, starting with the venous system and demonstrating both normal and pathologic states. It reviews the cerebral circulation with attention to the microsurgical relationships, angiographic patterns, and fusion of dual-volume imaging. The importance of bony, sulcal, and ventricular anatomy is presented as it relates to the angiographic representation of pathologic lesions. Examples are given of anatomic variants seen with the operating microscope, biplanar angiography, and three-dimensional rotational angiography." Note that in the synopsis and throughout the article, first person usage has been changed to third person per journal style.

  11. Clinical anatomy research in a research-driven anatomy department.

    2002-05-01

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

    2014-01-01

    Full Text Available In the traditional science of medicine and medical education, teaching human anatomy in the class has always been done using human cadavers. Not only does this violate human sanctity, but according to our research, it is not adequate to provide students with the alleged educational value that it is supposed to deliver. It is very cumbersome to organise all the aspects of cadaver care. Cadavers are also very limited when it comes to controlling their structures and any benefit is almost completely altered the first time the cadaver is used (dissected, and ironically, it is very weak at delivering actual real-life scenarios of a human body to students. Virtual anatomy has been a promising solution that many are counting on. But even today, we have not found a complete solution that combines all the benefits of using human cadavers and those introduced by its technical counterparts. "Soul Anatomy" aims to do just that. It brings the best of all worlds, from a natural intuitive control system, life-like feel of organs, precise accuracy in moving and controlling bodily structures, to the smallest details of being able to show medical information overlays from various medical databases connected to the internet; thus making use of technology in teaching human anatomy by providing a modern learning experience.

    To describe topographic and endoscopic anatomy of guinea pig ear for development of surgical approaches in experimental studies. Experimental study. Eight adult guinea pigs (Cavia porcellus) were used in this study. Four animals were described through endoscopic view and four animals were used to describe topographic anatomy. The main structures of middle ear were well identified through endoscopy view: oval and round window, ossicles and vascular structures. Temporal bone position, landmarks and its relations to skull are perceived with topographic description. Topographic anatomic description allowed exposition of temporal bone relations for external surgical approaches. Alternatively, grooves and middle ear structures were identified and may be used to transcanal accesses.

    Full Text Available Introduction. Cadaveric dissections and prosections have traditionally been part of undergraduate medical teaching. Materials and Methods. Hundred and fifty-nine first-year students in the Faculty of Medicine, University of Colombo, were invited to participate in the above study. Students were randomly allocated to two age and gender matched groups. Both groups were exposed to identical series of lectures regarding anatomy of the abdomen and conventional cadaveric prosections of the abdomen. The test group (n=77, 48.4% was also exposed to cadaveric cross-sectional slices of the abdomen to which the control group (n=82, 51.6% was blinded. At the end of the teaching session both groups were assessed by using their performance in a timed multiple choice question paper as well as ability to identify structures in abdominal CT films. Results. Scores for spatial and radiological anatomy were significantly higher among the test group when compared with the control group (P<0.05, CI 95%. Majority of the students in both control and test groups agreed that cadaveric cross section may be useful for them to understand spatial and radiological anatomy. Conclusion. Introduction of cadaveric cross-sectional prosections may help students to understand spatial and radiological anatomy better.

    This study investigated the integration, implementation, and use of cadaver dissection, hospital radiology modalities, surgical tools, and AV technology during a 12-week contemporary anatomy course suggesting a millennial laboratory. The teaching of anatomy has undergone the greatest fluctuation of any of the basic sciences during the past 100 years in order to make room for the meteoric rise in molecular sciences. Classically, anatomy consisted of a 2-year methodical, horizontal, anatomy course; anatomy has now morphed into a 12-week accelerated course in a vertical curriculum, at most institutions. Surface and radiological anatomy is the language for all clinicians regardless of specialty. The objective of this study was to investigate whether integration of full-body dissection anatomy and modern hospital technology, during the anatomy laboratory, could be accomplished in a 12-week anatomy course. Literature search was conducted on anatomy text, journals, and websites regarding contemporary hospital technology integrating multiple image mediums of 37 embalmed cadavers, surgical suite tools and technology, and audio/visual technology. Surgical and radiology professionals were contracted to teach during the anatomy laboratory. Literature search revealed no contemporary studies integrating full-body dissection with hospital technology and behavior. About 37 cadavers were successfully imaged with roentograms, CT, and MRI scans. Students were in favor of the dynamic laboratory consisting of multiple activity sessions occurring simultaneously. Objectively, examination scores proved to be a positive outcome and, subjectively, feedback from students was overwhelmingly positive. Despite the surging molecular based sciences consuming much of the curricula, full-body dissection anatomy is irreplaceable regarding both surface and architectural, radiological anatomy. Radiology should not be a small adjunct to understand full-body dissection, but rather, full-body dissection

    Dancers are highly susceptible to musculoskeletal injuries and frequently require interaction with medical professionals. While many dancers have a finely tuned awareness of their bodies, their knowledge of the fundamentals of human anatomy is not uniform. There is a paucity of literature on the benefits of human anatomy education in dancers, though it seems intuitive that there should be a relationship. The purpose of this study was to assess dancers' perceived and actual knowledge of basic musculoskeletal anatomy and its relationship to function. Adult dancers at the undergraduate, pre-professional, and professional levels were surveyed through an anonymous online questionnaire. Questions included demographic information, dance techniques studied, anatomy training, and injury history. Subjects rated their perceived knowledge of anatomy and were tested with 15 multiple-choice questions on basic musculoskeletal anatomy. Four hundred seventy-five surveys were completed. Ordinal regression showed a correlation of perceived to actual knowledge of anatomy (p < 0.001). Factors that correlated with increases in both perceived and actual knowledge of anatomy included having taken an anatomy course of any type (p < 0.001) and increased age (p ≤ 0.001). Years of dance training and professional dancer status both significantly correlated with increased knowledge of anatomy (p < 0.001) but not perceived knowledge. Chi-square analysis showed that dancers with training in either modern or jazz dance had a significantly higher perceived, but not actual, knowledge when compared to those without training in those styles of dance (p < 0.001 and p = 0.011, respectively). In conclusion, dancers generally scored well on questions pertaining to basic musculoskeletal anatomy, and their perception correlated with their actual knowledge of anatomy. Factors that contribute to dancers' knowledge of anatomy include age, years of experience, professional dancer status, and anatomy training.

    Abdominal ultrasonography was performed in six adult captive caracals (Caracal caracal) to describe the normal abdominal ultrasonographic anatomy. Consistently, the splenic parenchyma was hyperechoic to the liver and kidneys. The relative echogenicity of the right kidney's cortex was inconsistent to the liver. The gall bladder was prominent in five animals and surrounded by a clearly visualized thin, smooth, regular echogenic wall. The wall thickness of the duodenum measured significantly greater compared with that of the jejunum and colon. The duodenum had a significantly thicker mucosal layer compared with that of the stomach. Such knowledge of the normal abdominal ultrasonographic anatomy of individual species is important for accurate diagnosis and interpretation of routine health examinations.

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

On a contractarian view, research on animals is only an ethical issue to the extent that other humans as parties to the social contract care about how research animals...... are faring. From the utilitarian perspective, the use of sentient animals in research that may harm them is an ethical issue, but harm done to animals can be balanced by benefit generated for humans and other animals. The animal rights view, when thoroughgoing, is abolitionist as regards the use of animals...

    2009-01-01

    Full Text Available Effective brachial plexus blockade requires a thorough understanding of the anatomy of the plexus, as well as an appreciation of anatomic variations that may occur. This review summarizes relevant anatomy of the plexus, along with variations and anomalies that may affect nerve blocks conducted at these levels. The Medline, Cochrane Library, and PubMed electronic databases were searched in order to compile reports related to the anatomy of the brachial plexus using the following free terms: "brachial plexus", "median nerve", "ulnar nerve", "radial nerve", "axillary nerve", and "musculocutanous nerve". Each of these was then paired with the MESH terms "anatomy", "nerve block", "anomaly", "variation", and "ultrasound". Resulting articles were hand searched for additional relevant literature. A total of 68 searches were conducted, with a total of 377 possible articles for inclusion. Of these, 57 were found to provide substantive information for this review. The normal anatomy of the brachial plexus is briefly reviewed, with an emphasis on those features revealed by use of imaging technologies. Anomalies of the anatomy that might affect the conduct of the various brachial plexus blocks are noted. Brachial plexus blockade has been effectively utilized as a component of anesthesia for upper extremity surgery for a century. Over that period, our understanding of anatomy and its variations has improved significantly. The ability to explore anatomy at the bedside, with real-time ultrasonography, has improved our appreciation of brachial plexus anatomy as well.

    Hwang, Kun; Lee, Jung Hun; Lim, Hee Joong

    2017-03-01

    The aim of this article is to systematically review the anatomy and action of the corrugator muscle. PubMed and Scopus were searched using the terms "corrugator" AND "anatomy." Among the 60 full texts from the 145 relevant abstracts, 34 articles without sufficient content were excluded and 4 articles drawn from the reference lists were added. Among the 30 articles analyzed (721 hemifaces), 28% classified by oblique head and transverse head, and 72% did not. Corrugator originated mostly from the medial supraorbital rim (45%), followed by the medial frontal bone (31%), the medial infraorbital rim (17%), and the upper nasal process (7%). Corrugator extended through the frontalis and orbicularis oculi (41%), only the frontalis (41%), or only the orbicularis oculi (18%). Corrugator ran superolaterally (59%), or laterally (41%). Corrugators inserted mostly to the middle of the eyebrow (57%), or the medial half of the eyebrow (36%), but also to the glabella region (7%). The length of the corrugator ranged 38 to 53 mm. The transverse head (23.38 mm) was longer than the oblique head (19.75 mm). Corrugator was thicker at the medial canthus than at the midpupillary line. Corrugator was innervated by the temporal branch of the facial nerve (66%), the zygomatic branch (17%), or the angular nerve (zygomatic branch and buccal branch, 17%). Supraorbital nerve (60%) or supratrochlear nerve (40%) penetrated the corrugator. The action was depressing, pulling the eyebrow medially (91%), or with medial eyebrow elevation and lateral eyebrow depression (9%). Surgeons must keep this anatomy in mind during surgical procedures.

    1998-01-01

    This article provides a practical approach to the clinical implications and importance of understanding the collateral venous anatomy of the thorax. Routine radiography, conventional venography, computed tomography (CT), and magnetic resonance (MR) imaging studies provide correlative anatomic models for the demonstration of how interconnecting collateral vascular networks within the thorax maintain venous stability at all times. Five major systems comprise the collateral venous network of the thorax ( Fig. 1 ). These include the paravertebral, azygos-hemiazygos, internal mammary, lateral thoracic, and anterior jugular venous systems (AJVS). The five systems are presented in the following sequence: (a) a brief introduction to the importance of catheter position and malposition in understanding access to the thoracic venous system, (b) the anatomy of the azygos-hemiazygos systems and their relationship with the paravertebral plexus, (c) the importance of the AJVS, (d) 'loop' concepts interconnecting the internal mammary and azygos-hemiazygos systems by means of the lateral thoracic and intercostal veins, and (e) the interconnecting venous networks on the thoracic side of the thoracoabdominal junction. Certain aspects of the venous anatomy of the thorax will not be discussed in this chapter and include (a) the intra-abdominal anastomoses between the superior and inferior vena cavae (IVC) via the internal mammary, lateral thoracic, and azygos-hemiazygos systems (beyond the scope of this article), (b) potential collateral vessels involving vertebral, parascapular, thyroidal, thymic, and other smaller veins that might anastomose with the major systems, and (c) anatomic variants and pitfalls that may mimic pathologic conditions (space limitations).

    2002-01-01

    Information security involves many branches of effort, including information assurance, host level security, physical security, and network security. Computer network security methods and implementations are given a top-down description to permit a medically focused audience to anchor this information to their daily practice. The depth of detail of network functionality and security measures, like that of the study of human anatomy, can be highly involved. Presented at the level of major gross anatomical systems, this paper will focus on network backbone implementation and perimeter defenses, then diagnostic tools, and finally the user practices (the human element). Physical security measures, though significant, have been defined as beyond the scope of this presentation.

    2002-11-01

    We present an online anatomy atlas based on the Visible Human Project (VHP) of the US National Library of Medicine. The objective is to provide original unlabeled as well as labeled sections of the human body of high quality and resolution on the Internet, for use in basic and continuing medical education. For a representative overview of the body, 370 axial sections were selected from the male and female data base of the VHP with special regard to regions of clinical interest. Each section is accompanied by its corresponding computer tomography (CT) image and, if available, magnetic resonance images (MRI) for quick and easy comparison of morphologic and radiologic structures. The sections can be studied unlabeled or labeled according to the current Terminologia Anatomica. A linked vocabulary with more than 850 terms explains the labeling. Animations of the sections as well as of CT and MR images allow for further visualization of the topographic relationships of anatomical structures. The responses to the project indicate that students and physicians regard the Internet Atlas of Human Gross Anatomy as a most useful aid for learning and reviewing anatomical details. The atlas is accessible on: http://www.uni-mainz.de/FB/Medizin/Anatomie/workshop/vishuman/Eready.html. Copyright 2002 Wiley-Liss, Inc.

    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.

  11. Human fetal anatomy: MR imaging.

    Science.gov (United States)

    Weinreb, J C; Lowe, T; Cohen, J M; Kutler, M

    1985-12-01

    Twenty-four pregnant women carrying 26 fetuses (two sets of twins) were imaged with magnetic resonance (MR) imaging at 0.35 T following sonographic evaluation. Each study was retrospectively evaluated to determine which of 33 normal fetal structures were visible on the images and which imaging parameters were most useful for depicting fetal anatomy. Fetal motion degraded fetal images in all but two cases, both with oligohydramnios and in the third trimester of gestation. Nevertheless, many fetal structures were identifiable, particularly in the third trimester. Visualization of fetal anatomy improved with intravenous maternal sedation in five cases. Relatively T1-weighted images occasionally offered the advantage of less image degradation owing to fetal motion and improved contrast between different fetal structures. More T2 weighting was believed to be advantageous in one case for outlining the fetal head and in one case for delineation of the brain. In many cases, structures were similarly identifiable (though with different signal intensities) regardless of the parameters selected. The authors conclude that MR imaging of many fetal structures is currently unsatisfactory and is probably of limited value, particularly in the first and second trimesters. However, the relative frequency and detail with which the fetal head and liver can be depicted indicate that these may be areas for further investigation, and the potential utility of imaging fetal fat warrants further investigation.

  12. Anatomy of the Spinal Meninges.

    Science.gov (United States)

    Sakka, Laurent; Gabrillargues, Jean; Coll, Guillaume

    2016-06-01

    The spinal meninges have received less attention than the cranial meninges in the literature, although several points remain debatable and poorly understood, like their phylogenesis, their development, and their interactions with the spinal cord. Their constancy among the chordates shows their crucial importance in central nervous system homeostasis and suggests a role far beyond mechanical protection of the neuraxis. This work provides an extensive study of the spinal meninges, from an overview of their phylogenesis and embryology to a descriptive and topographic anatomy with clinical implications. It examines their involvement in spinal cord development, functioning, and repair. This work is a review of the literature using PubMed as a search engine on Medline. The stages followed by the meninges along the phylogenesis could not be easily compared with their development in vertebrates for methodological aspects and convergence processes throughout evolution. The distinction between arachnoid and pia mater appeared controversial. Several points of descriptive anatomy remain debatable: the functional organization of the arterial network, and the venous and lymphatic drainages, considered differently by classical anatomic and neuroradiological approaches. Spinal meninges are involved in neurodevelopment and neurorepair producing neural stem cells and morphogens, in cerebrospinal fluid dynamics and neuraxis functioning by the synthesis of active molecules, and the elimination of waste products of central nervous system metabolism. The spinal meninges should be considered as dynamic functional formations evolving over a lifetime, with ultrastructural features and functional interactions with the neuraxis remaining not fully understood.

  13. Animal models for human diseases.

    Science.gov (United States)

    Rust, J H

    1982-01-01

    The use of animal models for the study of human disease is, for the most part, a recent development. This discussion of the use of animal models for human diseases directs attention to the sterile period, early advances, some personal experiences, the human as the model, biological oddities among common laboratory animals, malignancies in laboratory animals, problems created by federal regulations, cancer tests with animals, and what the future holds in terms of the use of animal models as an aid to understanding human disease. In terms of early use of animal models, there was a school of rabbis, some of whom were also physicians, in Babylon who studied and wrote extensively on ritual slaughter and the suitability of birds and beasts for food. Considerable detailed information on animal pathology, physiology, anatomy, and medicine in general can be found in the Soncino Babylonian Talmudic Translations. The 1906 edition of the "Jewish Encyclopedia," has been a rich resource. Although it has not been possible to establish what diseases of animals were studied and their relationship to the diseases of humans, there are fascinating clues to pursue, despite the fact that these were sterile years for research in medicine. The quotation from the Talmud is of interest: "The medical knowledge of the Talmudist was based upon tradition, the dissection of human bodies, observation of disease and experiments upon animals." A bright light in the lackluster years of medical research was provided by Galen, considered the originator of research in physiology and anatomy. His dissection of animals and work on apes and other lower animals were models for human anatomy and physiology and the bases for many treatises. Yet, Galen never seemed to suggest that animals could serve as models for human diseases. Most early physicians who can be considered to have been students of disease developed their medical knowledge by observing the sick under their care. 1 early medical investigator

    1977-12-01

    In the interval from February of 1972 through December of 1977, studies were conducted relating to the anatomical feasibility of implanting a total artificial heart system. These studies included both the calf as an experimental animal as well as the ultimate human recipient of the artificial heart system. Studies with the calf included definition of the thoracic anatomy relative to the size, shape, and vascular connections for implanting the blood pump. To test the animal's tolerance to an implanted engine system, mockups of the thermal converter were implanted chronically in various locations within the calf. No problems developed in retroperitoneal or intraperitoneal implants ranging from 8 to 15 months. A study to determine accelerations experienced by an abdominally implanted thermal converter was performed in calves. Under the most severe conditions, accelerations of a maximum of 34 Gs were experienced. The largest effort was devoted to defining the human anatomy relative to implanting an artificial heart in the thorax. From a number of data sources, including cadavers as well as living patients, a quantitative, statistical analysis of the size and shape of the male thorax was obtained. Finally, an in vivo study of a functional intrathoracic compliance bag in a calf demonstrated the feasibility of this method.

  20. Use of synchrotron tomography to image naturalistic anatomy in insects

    2008-08-01

    Understanding the morphology of anatomical structures is a cornerstone of biology. For small animals, classical methods such as histology have provided a wealth of data, but such techniques can be problematic due to destruction of the sample. More importantly, fixation and physical slicing can cause deformation of anatomy, a critical limitation when precise three-dimensional data are required. Modern techniques such as confocal microscopy, MRI, and tabletop x-ray microCT provide effective non-invasive methods, but each of these tools each has limitations including sample size constraints, resolution limits, and difficulty visualizing soft tissue. Our research group at the Advanced Photon Source (Argonne National Laboratory) studies physiological processes in insects, focusing on the dynamics of breathing and feeding. To determine the size, shape, and relative location of internal anatomy in insects, we use synchrotron microtomography at the beamline 2-BM to image structures including tracheal tubes, muscles, and gut. Because obtaining naturalistic, undeformed anatomical information is a key component of our studies, we have developed methods to image fresh and non-fixed whole animals and tissues. Although motion artifacts remain a problem, we have successfully imaged multiple species including beetles, ants, fruit flies, and butterflies. Here we discuss advances in biological imaging and highlight key findings in insect morphology.

    Primary ciliary dyskinesia (PCD) is a respiratory syndrome in which 'random' organ orientation can occur; with approximately 46% of patients developing situs inversus totalis at organogenesis. The aim of this study was to explore the relationship between organ anatomy and curve convexity by studying the prevalence and convexity of idiopathic scoliosis in PCD patients with and without situs inversus. Chest radiographs of PCD patients were systematically screened for existence of significant lateral spinal deviation using the Cobb angle. Positive values represented right-sided convexity. Curve convexity and Cobb angles were compared between PCD patients with situs inversus and normal anatomy. A total of 198 PCD patients were screened. The prevalence of scoliosis (Cobb >10°) and significant spinal asymmetry (Cobb 5-10°) was 8 and 23%, respectively. Curve convexity and Cobb angle were significantly different within both groups between situs inversus patients and patients with normal anatomy (P ≤ 0.009). Moreover, curve convexity correlated significantly with organ orientation (P scoliosis (8 situs inversus and 8 normal anatomy), except for one case, matching of curve convexity and orientation of organ anatomy was observed: convexity of the curve was opposite to organ orientation. This study supports our hypothesis on the correlation between organ anatomy and curve convexity in scoliosis: the convexity of the thoracic curve is predominantly to the right in PCD patients that were 'randomized' to normal organ anatomy and to the left in patients with situs inversus totalis.

  3. Human cadavers Vs. multimedia simulation: A study of student learning in anatomy.

    2014-01-01

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

    2016-03-01

    Comparative anatomy and physiology are disciplines related to structures and mechanisms in three-dimensional (3D) space. For the past centuries, scientific reports in these fields have relied on written descriptions and two-dimensional (2D) illustrations, but in recent years 3D virtual modelling has entered the scene. However, comprehending complex anatomical structures is hampered by reproduction on flat inherently 2D screens. One way to circumvent this problem is in the production of 3D-printed scale models. We have applied computed tomography and magnetic resonance imaging to produce digital models of animal anatomy well suited to be printed on low-cost 3D printers. In this communication, we report how to apply such technology in comparative anatomy and physiology to aid discovery, description, comprehension and communication, and we seek to inspire fellow researchers in these fields to embrace this emerging technology.

    1993-08-01

    The anatomical literature has indicated that the arterial supply to the thumb comes from the princeps pollicis artery. However, this simplified description does not often correlate with intraoperative findings. The purpose of this study was to investigate and clarify this important area of anatomy by dissection of fresh cadaver hands. 40 dissections were completed on 35 intravascularly injected and five non-injected hands. Five patterns were identified. The most common pattern showed both a superficial and deep vessel to the first web space in 54% of specimens. Dominant vessels included the superficial palmar branch of the radial artery in 8%, first palmar metacarpal artery in 18% and dorsal metacarpal artery in 8%. Only three specimens correlated with the textbook description. We conclude that the term "princeps pollicis" is actually a misnomer.

  8. Anterior ethmoid anatomy facilitates dacryocystorhinostomy.

    1990-12-01

    The ethmoid air cell labyrinth lies adjacent to the medial orbital wall, extending even beyond the sutures of the ethmoid bone. Its anatomic relationship to the lacrimal sac fossa is important in lacrimal surgery. We evaluated computed tomographic scans of 190 orbits with normal ethmoid anatomy to define the anatomic relationship of anterior ethmoid air cells to the lacrimal sac fossa. In 93% of the orbits, the cells extended anterior to the posterior lacrimal crest, with 40% entering the frontal process of the maxilla. This anatomic relationship may be used to facilitate the osteotomy during dacryocystorhinostomy. During a 10-year period (310 cases), one of us routinely entered the anterior ethmoid air cells to initiate the osteotomy during dacryocystorhinostomy. This technique has helped to avoid lacerations of the nasal mucosa.

    The aim of this paper was to review the anatomy the platysma systematically.The term "platysma AND anatomy" was used to search PubMed and Scopus, producing 394 and 214 papers, respectively. After excluding 95 duplicate titles, 513 abstracts and 98 full papers were reviewed. Among these 98 papers, 83 were excluded and 5 were added. Ultimately, 20 papers were analyzed.The most common aging-related change of the platysma was shortening (70.7%), followed by thinning (25.2%). The platysma most commonly originated from the upper portion of thorax anterior to clavicle (67.7%), followed by the subcutaneous tissue of the subclavicular and acromial regions (22.6%) and pectoralis (9.7%). The platysma ascended upward and medially (68.5%) or ascended from the clavicle to the face (31.5%). The platysma most commonly inserted on the cheek skin (57.5%), followed by the cutaneous muscles around the mouth (18.6%), the mandibulocutaneous ligament or zygoma (18.6%), and the parotid fascia or periosteum of the mandible (5.3%). The platysma was most commonly innervated by the cervical branch of the facial nerve (38.2%) or the cervical branch and mandibular branch of the facial nerve (60.5%), followed by the cervical plexus (0.6%), the cervical motor nucleus (0.6%), and the glossopharyngeal nerve (0.1%). The most common action of the platysma was drawing the lips inferiorly (83.3%) or posteriorly (12.9%). Four papers classified the platysma into subtypes; however, these classification strategies used arbitrary standards.Further studies will be necessary to establish the thickness of the platysma and to characterize age-related changes of the platysma.

    Precise MEG estimates of neuronal current flow are undermined by uncertain knowledge of the head location with respect to the MEG sensors. This is either due to head movements within the scanning session or systematic errors in co-registration to anatomy. Here we show how such errors can be minimized using subject-specific head-casts produced using 3D printing technology. The casts fit the scalp of the subject internally and the inside of the MEG dewar externally, reducing within session and between session head movements. Systematic errors in matching to MRI coordinate system are also reduced through the use of MRI-visible fiducial markers placed on the same cast. Bootstrap estimates of absolute co-registration error were of the order of 1mm. Estimates of relative co-registration error were <1.5mm between sessions. We corroborated these scalp based estimates by looking at the MEG data recorded over a 6month period. We found that the between session sensor variability of the subject's evoked response was of the order of the within session noise, showing no appreciable noise due to between-session movement. Simulations suggest that the between-session sensor level amplitude SNR improved by a factor of 5 over conventional strategies. We show that at this level of coregistration accuracy there is strong evidence for anatomical models based on the individual rather than canonical anatomy; but that this advantage disappears for errors of greater than 5mm. This work paves the way for source reconstruction methods which can exploit very high SNR signals and accurate anatomical models; and also significantly increases the sensitivity of longitudinal studies with MEG. © 2013.

    Precise MEG estimates of neuronal current flow are undermined by uncertain knowledge of the head location with respect to the MEG sensors. This is either due to head movements within the scanning session or systematic errors in co-registration to anatomy. Here we show how such errors can be minimized using subject-specific head-casts produced using 3D printing technology. The casts fit the scalp of the subject internally and the inside of the MEG dewar externally, reducing within session and between session head movements. Systematic errors in matching to MRI coordinate system are also reduced through the use of MRI-visible fiducial markers placed on the same cast. Bootstrap estimates of absolute co-registration error were of the order of 1 mm. Estimates of relative co-registration error were < 1.5 mm between sessions. We corroborated these scalp based estimates by looking at the MEG data recorded over a 6 month period. We found that the between session sensor variability of the subject's evoked response was of the order of the within session noise, showing no appreciable noise due to between-session movement. Simulations suggest that the between-session sensor level amplitude SNR improved by a factor of 5 over conventional strategies. We show that at this level of coregistration accuracy there is strong evidence for anatomical models based on the individual rather than canonical anatomy; but that this advantage disappears for errors of greater than 5 mm. This work paves the way for source reconstruction methods which can exploit very high SNR signals and accurate anatomical models; and also significantly increases the sensitivity of longitudinal studies with MEG.

    Historically, cadavers have been used for the study of anatomy. Nowadays, the territorial and legal limitations of this approach have led to the introduction of alternative teaching methods such as the use of practical exercise consisting of dissection and observation of animal organs. The aim of this study was to evaluate the use of practical training on animal organs compared with the traditional method of anatomy teaching, based on the dissection of human cadavers. In this study, we seek to demonstrate the usefulness of practical exercise on animal organs. This practical training was held a week after the series of lectures, thus leaving time for the students to learn and understand the topics discussed. Immediately after the lecture, all of the students completed a preliminary test to assess the immediate effect of the lecture. Immediately before the practical exercise, both control and experimental groups completed a second test to assess the effectiveness of personal study. Immediately after practical training, a third test was completed by the experimental group and the control group (no practical activity on animal organs) to highlight the added value of hands-on practice in addition to the lecture. Data obtained from statistical analysis showed a panatomy learning between control and experimental groups. Thus, the results of this study emphasize the utility of practical training on animal organs in learning and understanding anatomy, considering the limitations of the use of cadavers.

  6. Comparative anatomy of the thigh nerves of Cebus libidinosus (Rylands et al., 2000

    Directory of Open Access Journals (Sweden)

    2011-03-01

    Full Text Available Non-human primates have constituted an important group among animals subjected to various studies. Ethological, evolutionary and paleontological studies have revealed changes in anatomical structures linked to the evolution of primates, considered in studies on the comparative anatomy between Cebus libidinosus and other neotropical monkeys or those from the Old World, and the detailed knowledge on their anatomy may represent an important factor for their preservation and protection when the animals are brought to veterinary clinics after accidents or illnesses. In terms of veterinary importance, sometimes these animals arrive in the veterinary medical clinics after accidents, needing surgery or clinical treatment, but the little data available on anatomy has impaired the correct proceedings. The main justification for studies on C. libidinosus, is due to little information about the anatomy related to C. libidinosus in Brazilian and worldwide scientific literature. In this study, the distribution, enervation and path of the femoral and sciatic nerves of the pelvic limb (thigh of C. libidinosus were studied and these results were compared with literature on the anatomy of humans, chimpanzees and baboons. In general, the enervation model of the four primates is identical, but in specific terms, the differences in enervations indicate evolution convergence closer to the branch of baboons in the evolutionary tree, and these data corroborate other comparative studies in relation to the same primates to vessels, muscles and nerves. In conclusion, the nerve organization in the thigh of C. libidinosus is identical to baboon, chimpanzee and homo, but more similar to baboon. The specific differences found indicate an ancient phylogenic origin to C. libidinosus and baboons (data corroborated by other studies.

    2006-10-01

    Surface anatomy is an integral part of medical education and enables medical students to learn skills for future medical practice. In the past decade, there has been a decline in the teaching of anatomy in the medical curriculum, and this study seeks to assess the attitudes of medical students to participation in surface anatomy classes. Consequently, all first year medical students at the Guy's, King's and St Thomas's Medical School, London, were asked to fill in an anonymous questionnaire at the end of their last surface anatomy session of the year. A total of 290 medical students completed the questionnaires, resulting in an 81.6% response rate. The students had a mean age of 19.6 years (range 18-32) and 104 (35.9%) of them were male. Seventy-six students (26.2%) were subjects in surface anatomy tutorials (60.5% male). Students generally volunteered because no one else did. Of the volunteers, 38.2% would rather not have been subjects, because of embarrassment, inability to make notes, or to see clearly the material being taught. Female medical students from ethnic minority groups were especially reluctant to volunteer to be subjects. Single-sex classes improved the volunteer rate to some extent, but not dramatically. Students appreciate the importance of surface anatomy to cadaveric study and to future clinical practice. Computer models, lectures, and videos are complementary but cannot be a substitute for peer group models, artists' models being the only alternative. Copyright 2006 Wiley-Liss, Inc.

    2007-02-01

    Félix Vicq d'Azyr was born in 1748 in the small town of Valognes, Normandy. He studied medicine in Paris but he was particularly impressed by the lectures given at the Jardin du Roi by the comparative anatomist Louis Daubenton and the surgeon Antoine Petit. In 1773, Vicq d'Azyr initiated a series of successful lectures on human and animal anatomy at the Paris Medical School, from which he received his medical degree in 1774. He was elected the same year at the Academy of Sciences at age 26, thanks to his outstanding contributions to comparative anatomy. Vicq d'Azyr became widely known after his successful management of a severe cattle plague that occurred in the southern part of France in 1774, an event that led to the foundation of the Royal Society of Medicine in 1778. As Permanent Secretary of this society, Vicq d'Azyr wrote several eulogies that were models of eloquence and erudition and worth him a seat at the French Academy in 1788. Vicq d'Azyr published in 1786 a remarkable anatomy and physiology treatise: a large in-folio that contained original descriptions illustrated by means of nature-sized, colored, human brain figures of a quality and exactitude never attained before. In 1789, Vicq d'Azyr was appointed physician to the Queen Marie-Antoinette and, in 1790, he presented to the Constituent Assembly a decisive plan to reform the teaching of medicine in France. Unfortunately, Vicq d'Azyr did not survive the turmoil of the French Revolution; he died at age 46 on June 20, 1794.

  14. Molecular Anatomy of Palate Development.

    Directory of Open Access Journals (Sweden)

    Andrew S Potter

    Full Text Available The NIH FACEBASE consortium was established in part to create a central resource for craniofacial researchers. One purpose is to provide a molecular anatomy of craniofacial development. To this end we have used a combination of laser capture microdissection and RNA-Seq to define the gene expression programs driving development of the murine palate. We focused on the E14.5 palate, soon after medial fusion of the two palatal shelves. The palate was divided into multiple compartments, including both medial and lateral, as well as oral and nasal, for both the anterior and posterior domains. A total of 25 RNA-Seq datasets were generated. The results provide a comprehensive view of the region specific expression of all transcription factors, growth factors and receptors. Paracrine interactions can be inferred from flanking compartment growth factor/receptor expression patterns. The results are validated primarily through very high concordance with extensive previously published gene expression data for the developing palate. In addition selected immunostain validations were carried out. In conclusion, this report provides an RNA-Seq based atlas of gene expression patterns driving palate development at microanatomic resolution. This FACEBASE resource is designed to promote discovery by the craniofacial research community.

  17. Animal experimentation.

    Kolar, Roman

    2006-01-01

    Millions of animals are used every year in often times extremely painful and distressing scientific procedures. Legislation of animal experimentation in modern societies is based on the supposition that this is ethically acceptable when certain more or less defined formal (e.g. logistical, technical) demands and ethical principles are met. The main parameters in this context correspond to the "3Rs" concept as defined by Russel and Burch in 1959, i.e. that all efforts to replace, reduce and refine experiments must be undertaken. The licensing of animal experiments normally requires an ethical evaluation process, often times undertaken by ethics committees. The serious problems in putting this idea into practice include inter alia unclear conditions and standards for ethical decisions, insufficient management of experiments undertaken for specific (e.g. regulatory) purposes, and conflicts of interest of ethics committees' members. There is an ongoing societal debate about ethical issues of animal use in science. Existing EU legislation on animal experimentation for cosmetics testing is an example of both the public will for setting clear limits to animal experiments and the need to further critically examine other fields and aspects of animal experimentation.

  18. Animal Bioacoustics

    Science.gov (United States)

    Fletcher, Neville H.

    Animals rely upon their acoustic and vibrational senses and abilities to detect the presence of both predators and prey and to communicate with members of the same species. This chapter surveys the physical bases of these abilities and their evolutionary optimization in insects, birds, and other land animals, and in a variety of aquatic animals other than cetaceans, which are treated in Chap. 20. While there are many individual variations, and some animals devote an immense fraction of their time and energy to acoustic communication, there are also many common features in their sound production and in the detection of sounds and vibrations. Excellent treatments of these matters from a biological viewpoint are given in several notable books [19.1,2] and collections of papers [19.3,4,5,6,7,8], together with other more specialized books to be mentioned in the following sections, but treatments from an acoustical viewpoint [19.9] are rare. The main difference between these two approaches is that biological books tend to concentrate on anatomical and physiological details and on behavioral outcomes, while acoustical books use simplified anatomical models and quantitative analysis to model vocalization frequency scaling in animals hearing sound production animal animal biological biological bioacoustics whole-system behavior. This latter is the approach to be adopted here.

    Modern data on studying and teaching topographic and clinical anatomy in Russia and in the foreign countries at the boundary between the XX and the XXI centuries are analyzed. Definitions of some concepts are given; methodological and organizational bases of studying topographic and clinical anatomy are examined in historical aspect. Various approaches to the teaching and studying of these disciplines in different countries, are demonstrated. Special attention is given to the use of new technologies in teaching; the experience of virtual mode of studying of applied anatomy and surgical techniques is critically evaluated. Article presents author's own opinion and analyzes the conceptions of the foreign authors on the necessity of rational combination of computer and other modem technologies with traditional methods of work using biological materials and experiments on laboratory animals. The longstanding experience of the departments of operative surgery and clinical anatomy is summarized and the benefits of the national system of teaching of applied (topographic and clinical) anatomy are shown. Modem tendencies and priorities in the development of topographic and clinical anatomy are demonstrated.

    Despite the cheetah being the fastest living land mammal, we know remarkably little about how it attains such high top speeds (29 m s(-1)). Here we aim to describe and quantify the musculoskeletal anatomy of the cheetah forelimb and compare it to the racing greyhound, an animal of similar mass, but which can only attain a top speed of 17 m s(-1). Measurements were made of muscle mass, fascicle length and moment arms, enabling calculations of muscle volume, physiological cross-sectional area (PCSA), and estimates of joint torques and rotational velocities. Bone lengths, masses and mid-shaft cross-sectional areas were also measured. Several species differences were observed and have been discussed, such as the long fibred serratus ventralis muscle in the cheetah, which we theorise may translate the scapula along the rib cage (as has been observed in domestic cats), thereby increasing the cheetah's effective limb length. The cheetah's proximal limb contained many large PCSA muscles with long moment arms, suggesting that this limb is resisting large ground reaction force joint torques and therefore is not functioning as a simple strut. Its structure may also reflect a need for control and stabilisation during the high-speed manoeuvring in hunting. The large digital flexors and extensors observed in the cheetah forelimb may be used to dig the digits into the ground, aiding with traction when galloping and manoeuvring. © 2011 The Authors.

    The function of the lower urinary tract is basically storage of urine in the bladder and the at-will periodic evacuation of the stored urine. Urinary incontinence is one of the most common lower urinary tract disorders in adults, but especially in the elderly female. The urethra, its sphincters, and the pelvic floor are key structures in the achievement of continence, but their basic anatomy is little known and, to some extent, still incompletely understood. Because questions with respect to continence arise from human morbidity, but are often investigated in rodent animal models, we present findings in human and rodent anatomy and histology. Differences between males and females in the role that the pelvic floor plays in the maintenance of continence are described. Furthermore, we briefly describe the embryologic origin of ureters, bladder, and urethra, because the developmental origin of structures such as the vesicoureteral junction, the bladder trigone, and the penile urethra are often invoked to explain (clinical) observations. As the human pelvic floor has acquired features in evolution that are typical for a species with bipedal movement, we also compare the pelvic floor of humans with that of rodents to better understand the rodent (or any other quadruped, for that matter) as an experimental model species. The general conclusion is that the "Bauplan" is well conserved, even though its common features are sometimes difficult to discern.

    The etiology of craniofacial defects is incompletely understood. The ability to obtain large amounts of gene sequence data from families affected by craniofacial defects is opening up new ways to understand molecular genetic etiological factors. One important link between gene sequence data and clinical relevance is biological research into candidate genes and molecular pathways. We present our recent research using OCT as a nondestructive phenotyping modality of craniofacial morphology in Xenopus embryos, an important animal model for biological research in gene and pathway discovery. We define 2D and 3D scanning protocols for a standardized approach to craniofacial imaging in Xenopus embryos. We define standard views and planar reconstructions for visualizing normal anatomy and landmarks. We compare these views and reconstructions to traditional histopathology using alcian blue staining. In addition to being 3D, nondestructive, and having much faster throughout, OCT can identify craniofacial features that are lost during traditional histopathological preparation. We also identify quantitative morphometric parameters to define normative craniofacial anatomy. We also note that craniofacial and cardiac defects are not infrequently present in the same patient (e.g velocardiofacial syndrome). Given that OCT excels at certain aspects of cardiac imaging in Xenopus embryos, our work highlights the potential of using OCT and Xenopus to study molecular genetic factors that impact both cardiac and craniofacial development.

  6. [Anatomia practica: features from the history of early patho-anatomy].

    Jensen, Olaf Myhre

    2002-01-01

    Since the anatomy school of Alexandria during the fourth og third century before Christ dissection of the human body seems not to have been practiced until late Medieval or early Renaissance period, undoubtedly due to ethical and religious aversions. The teaching of anatomy was based on Galen using animal dissection. In the fourteenth and fifteenth centuries, however, anatomical examinations of the human body slowly began, seemingly for the purpose of describing both the normal structure and the abnormal structure caused by diseases, maldevelopment or trauma. This latter branch of anatomy was called practical, medical or correlative anatomy and corresponds to what we today name as patho-anatomy. Antonio Benivieni of Florence (1442-1502) is the first one to collect (and publish) a series of clinical observations some of which could be correlated to post mortem findings. It is unknown, however, whether the autopsies were performed by himself; and there is no mentioning of technique or circumstances for sectioning. Studies of the dead body by incision for the purpose of displaying diseased organs (autopsy) seem to have been an accepted practice for which relatives consented in those days. Other medical doctors in the years to follow, as for instance Fernel (1485-1558) in Paris, Eustachius (1524-1574) in Rome, Felix Plater (1536-1614) in Basle and Th. Bartholin (1616-1680) in Copenhagen have used the anatomical method for the study of diseases. Further, Schenck (1530-1598) in Freiburg and Bonet (1620-1689) in Genéva collected and published large series of clinical symptoms which had been related to post mortem findings dating back to ancient observers. This is the scientific background for anatomists as Morgagni, Lieutaud, Baillie, Bichât and others who founded the morbid anatomy on which the study of disease flourished in the classical patho-anatomical era of the nineteenth century with names as Rokitanski and Virchow.

    In What do pictures want? The lives and loves of images (2005) J. W. T. Mitchell writes about pictures as “vital signs”, not signs for living things, but signs as living things (Mitchell 6). With a notion from the German art historian and media theorist Hans Belting this symbolic act can be called...... “animation”, defined as “an innate (and learnable) ability of our bodies to discover life in inanimate images” (Belting 2012, 188). In this essay I investigate the animation of pictures in dialogue with Mitchell, both by addressing general questions such as: how is animation of otherwise static pictures...... to be understood? How does animation differ in different media? And in particular by focusing on and questioning the gender positions inherent in Mitchell’s theory. Animation has an erotic component of seduction and desire, and what pictures want, becomes for Mitchell, what women want. There is of course no simple...

  9. Mentalizing animals

    Ethicists have tended to treat the psychology of attributing mental states to animals as an entirely separate issue from the moral importance of animals’ mental states. In this paper I bring these two issues together. I argue for two theses, one descriptive and one normative. The descriptive thesis...... holds that ordinary human agents use what are generally called phenomenal mental states (e.g., pain and other emotions) to assign moral considerability to animals. I examine recent empirical research on the attribution of phenomenal states and agential states (e.g., memory and intelligence) to argue...... that phenomenal mental states are the primary factor, psychologically, for judging an animal to be morally considerable. I further argue that, given the role of phenomenal states in assigning moral considerability, certain theories in animal ethics will meet significant psychological resistance. The normative...

Emotions are our universal language, the motivation of living, the key to what makes a movie successful and truly an art piece that you will remember because moves you. Animation......, indeed, can be considered a social/ emotional learning media, which goes beyond the limitations of live action movies. This is due to the diversity of techniques, and its visual plasticity that constructs the impossible.

    There are few trained veterinary radiation oncologists and the expense of facilities has limited the extent to which this modality is used. In recent years, a few cobalt teletherapy units and megavoltage x-ray units have been employed in larger veterinary institutions. In addition, some radiation oncologists of human medical institutions are interested and willing to cooperate with veterinarians in the treatment of animal tumors. Carefully designed studies of the response of animal tumors to new modalities serve two valuable purposes. First, these studies may lead to improved tumor control in companion animals. Second, these studies may have important implications to the improvement of therapy of human tumors. Much remains to be learned of animal tumor biology so that appropriate model systems can be described for such studies. Many of the latter studies can be sponsored by agencies interested in the improvement of cancer management

  14. Anatomy of the ward round.

    LENUS (Irish Health Repository)

    O'Hare, James A

    2008-07-01

    The ward round has been a central activity of hospital life for hundreds of years. It is hardly mentioned in textbooks. The ward round is a parade through the hospital of professionals where most decision making concerning patient care is made. However the traditional format may be intimidating for patients and inadequate for communication. The round provides an opportunity for the multi-disciplinary team to listen to the patient\\'s narrative and jointly interpret his concerns. From this unfolds diagnosis, management plans, prognosis formation and the opportunity to explore social, psychological, rehabilitation and placement issues. Physical examination of the patient at the bedside still remains important. It has been a tradition to discuss the patient at the bedside but sensitive matters especially of uncertainty may better be discussed elsewhere. The senior doctor as round leader must seek the input of nursing whose observations may be under-appreciated due to traditional professional hierarchy. Reductions in the working hours of junior doctors and shortened length of stay have reduced continuity of patient care. This increases the importance of senior staff in ensuring continuity of care and the need for the joint round as the focus of optimal decision making. The traditional round incorporates teaching but patient\\'s right to privacy and their preferences must be respected. The quality and form of the clinical note is underreported but the electronic record is slow to being accepted. The traditional multi-disciplinary round is disappearing in some centres. This may be regrettable. The anatomy and optimal functioning of the ward round deserves scientific scrutiny and experimentation.

  15. The globalisation of farm animal welfare.

    Science.gov (United States)

    Fraser, D

    2014-04-01

    Animal welfare has achieved significant global prominence for perhaps three reasons. First, several centuries of scientific research, especially in anatomy, evolutionary biology and animal behaviour, have led to a gradual narrowing of the gap that people perceive between humans and other species; this altered perception has prompted grass-roots attention to animals and their welfare, initially in Western countries but now more globally asthe influence of science has expanded. Second, scientific research on animal welfare has provided insights and methods for improving the handling, housing and management of animals; this 'animal welfare science' is increasingly seen as relevant to improving animal husbandry worldwide. Third, the development and use of explicit animal welfare standards has helped to integrate animal welfare as a component of national and international public policy, commerce and trade. To date, social debate about animal welfare has been dominated bythe industrialised nations. However, as the issue becomes increasingly global, it will be important for the non-industrialised countries to develop locally appropriate approaches to improving animal welfare, for example, by facilitating the provision of shelter, food, water and health care, and by improving basic handling, transportation and slaughter.

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

  17. Anatomy in a modern medical curriculum.

    2007-03-01

    Anatomy in undergraduate education has been in decline for many years. Some suggest that it has fallen below a safe level. Balances between detail and safety, and assimilation and application of anatomy have yet to be established as the methods of teaching undergo another metamorphosis. For doctors, the human body is the focus of investigation and intervention on a daily basis; for this reason, the study of anatomy in some form will continue to be essential to safe medical practice. It is necessary for core knowledge of anatomy to be assimilated by all doctors in order to practice and communicate safely. It may be true that most doctors do not need to dissect a cadaver or study a prosection in order to practice, but if it can improve their understanding of what they do and why they do it, this surely has to be of benefit both for the safety of the patient and satisfaction of the doctor as a professional. Integration of newer teaching modalities and modern technology will encourage interest and retention of anatomical knowledge and its clinical relevance. Anatomy has a promising future in postgraduate specialist and surgical training. Detailed knowledge should be integrated into specialist training when it is clinically relevant allowing specialists of the future to practice safely and accurately and also to provide a strong base for future clinical developments.

  18. Approach to the study of human anatomy.

    Ridola, Carlo

    2004-01-01

    The first thing to do to describe the human body is to define the anatomical position and the bilateral symmetry which characterise every Metazoi (man included) and permit us to study the body in its two symmetric halves; the left and right sides are the result of a virtual cut on a vertical and median plan. This is followed by a resume of the general structures and the vocabulary of the outer shapes of the human body; its direction (it will be helpful to use the virtual geometric parallelepiped made by three couples of planes one orthogonal to the other); levels of structural organization (chemical, cellular, tissue, organ and the system level; the highest is the organism level). After that, rules and principles are enunciated in the four fundamental laws of anatomy regarding the organ structures and their systems studied by the surface, gross (macroscopic), systemic, regional and constitutional type anatomy. There is also some information concerning education and research, the competence of the Human Anatomy as recommended by art. 1 of D.M. 23. XI. 1999 of the Italian law. Later what Richard Snell written in the preface to "Clinical Anatomy for Medical Students" about the importance of the knowledge of human anatomy for medical and surgical applications will be reported.

    Much has been postulated about the perceived deterioration of anatomy knowledge amongst graduates. Little is known about levels of confidence in, and educational needs concerning, clinical anatomy knowledge amongst foundation year doctors. To establish foundation year doctors' perceptions of anatomy related to: importance to career, confidence in anatomy knowledge and its application, preferred methods of teaching. Secondarily, to determine impact of an integrated clinical approach to anatomy teaching on foundation year doctors' level of knowledge and confidence in its clinical application of anatomy. A course teaching anatomy through common surgeries and related radiology was delivered to foundation year doctors. A pre- and post-course assessment based on anatomy competence score assessed holistic knowledge acquisition. Foundation year doctors' perceptions of anatomy and course satisfaction were measured through questionnaire. Confidence in applying anatomy knowledge was low. The average pre- and post-course assessment score increased from 55% to 81%; 92.86% felt an integrated clinical approach to anatomy teaching improved their confidence on the subject and 58.62% felt it improved their clinical skills. This study identified a need for ongoing educational support for foundation year doctors regarding anatomy teaching. An integrated clinical approach to teaching anatomy proved both highly relevant and popular, as well as an effective teaching approach. © The Author(s) 2015.

    The use of swine for teaching purposes in medicine and surgery has largely increased in recent years. Detailed knowledge of the porcine anatomy and physiology is a prerequisite for proper use of pigs as a teaching or an experimental model in interventional radiology. A systematic study of the radiological anatomy was undertaken in more than 100 female pigs aged 6-8 weeks. All studies were performed under general anesthesia in a single session. Animals were sacrificed at the end of the study. Selective angiographies were systematically obtained in all anatomical territories. In other animals CT and MRI examinations were performed and were correlated to anatomical sections and acrylic casts of the vascular structures. Endoscopical examinations of the upper gastrointestinal tract, including retrograde opacification of the biliary and pancreatic ducts, were added in selected animals. The main angiographic aspects of the brain, head and neck, thorax, abdomen, and pelvis were recorded. Similarities and differences in comparison with human anatomy are stressed. Potential applications in interventional radiology are indicated. (orig.)

  1. Cat dissection and human cadaver prosection versus sculpting human structures from clay: A comparison of alternate approaches to human anatomy laboratory education

    Science.gov (United States)

    Waters, John R.

    Dissection and vivisection are traditional approaches to biology laboratory education. In the case of human anatomy teaching laboratories, there is a long tradition of using human and animal cadaver specimens in the classroom. In a review of the literature comparing traditional dissection and vivisection lessons to alternative lessons designed to reduce the time spent dissecting or the numbers of animals used, we conclude that it is difficult to come to any conclusion regarding the efficacy of different approaches. An analysis of the literature is confounded because many studies have very low statistical power or other methodological weaknesses, and investigators rely on a wide variety of testing instruments to measure an equally varied number of course objectives. Additional well designed studies are necessary before educators can reach any informed conclusions about the efficacy of traditional versus alternative approaches to laboratory education. In our experiments, we compared a traditional cat dissection based undergraduate human anatomy lesson to an alternative where students sculpted human muscles onto plastic human skeletons. Students in the alternative treatment performed significantly better than their peers in the traditional treatment when answering both lower and higher order human anatomy questions. In a subsequent experiment with a similar design, we concluded that the superior performance of the students in the alternative treatment on anatomy exams was likely due to the similarity between the human anatomy representation studied in lab, and the human anatomy questions asked on the exams. When the anatomy questions were presented in the context of a cat specimen, students in the traditional cat dissection treatment outperformed their peers in the alternative treatment. In a final experiment where student performance on a human anatomy exam was compared between a traditional prosected human cadaver treatment and the alternative clay sculpting

    2014-07-01

    The anatomy of joints provides an important basis for understanding the nature and imaging of pathologic lesions and their imaging appearance. This applies especially to the sacroiliac (SI) joints, which play a major role in the diagnosis of spondyloarthritis. They are composed of two different joint portions, a cartilage-covered portion ventrally and a ligamentous portion dorsally, and thus rather complex anatomically. Knowledge of anatomy and the corresponding normal imaging findings are important in the imaging diagnosis of sacroiliitis, especially by MR imaging. A certain distinction between the two joint portions by MR imaging is only obtainable by axial slice orientation. Together with a perpendicular coronal slice orientation, it provides adequate anatomical information and thereby a possibility for detecting the anatomical site of disease-specific characteristics and normal variants simulating disease. This overview describes current knowledge about the normal macroscopic and microscopic anatomy of the SI joints. Thieme Medical Publishers 333 Seventh Avenue, New York, NY 10001, USA.

  4. Ontology-enriched Visualization of Human Anatomy

    Pouchard, LC

    2005-12-20

    The project focuses on the problem of presenting a human anatomical 3D model associated with other types of human systemic information ranging from physiological to anatomical information while navigating the 3D model. We propose a solution that integrates a visual 3D interface and navigation features with the display of structured information contained in an ontology of anatomy where the structures of the human body are formally and semantically linked. The displayed and annotated anatomy serves as a visual entry point into a patient's anatomy, medical indicators and other information. The ontology of medical information provides labeling to the highlighted anatomical parts in the 3D display. Because of the logical organization and links between anatomical objects found in the ontology and associated 3D model, the analysis of a structure by a physician is greatly enhanced. Navigation within the 3D visualization and between this visualization and objects representing anatomical concepts within the model is also featured.

    Head and neck anatomy is complex and represents an educational challenge to the student. Conventional two-dimensional illustrations inherently fall short in conveying intricate anatomical relationships that exist in three dimensions. A gratis three-dimensional virtual reality atlas of craniofacial anatomy is presented in an effort to address the paucity of readily accessible and customizable three-dimensional educational material available to the student of head and neck anatomy. Three-dimensional model construction was performed in Alias Maya 4.5 and 6.0. A basic three-dimensional skull model was altered to include surgical landmarks and proportions. Some of the soft tissues were adapted from previous work, whereas others were constructed de novo. Texturing was completed with Adobe Photoshop 7.0 and Maya. The Internet application was designed in Viewpoint Enliven 1.0. A three-dimensional computer model of craniofacial anatomy (bone and soft tissue) was completed. The model is compatible with many software packages and can be accessed by means of the Internet or downloaded to a personal computer. As the three-dimensional meshes are publicly available, they can be extensively manipulated by the user, even at the polygonal level. Three-dimensional computer graphics has yet to be fully exploited for head and neck anatomy education. In this context, the authors present a publicly available computer model of craniofacial anatomy. This model may also find applications beyond clinical medicine. The model can be accessed gratis at the Plastic and Reconstructive Surgery Web site or obtained as a three-dimensional mesh, also gratis, by contacting the authors.

    The chapter evaluates results of toxicological studies on experimental animals to investigate health effects of air pollutants and examines the animal data have predicted the response to human subject. Data are presented on the comparative toxicity of sulfur dioxide and sulfuric acid. The animal data obtained by measurement of airway resistance in guinea pigs and of bronchial clearance of particles in donkeys predicted clearly that sulfuric acid was more irritant than sulfur dioxide. Data obtained on human subjects confirmed this prediction. These acute studies also correctly predicted the comparative toxicity of the two compounds in two year studies of monkeys. Such chronic studies are not possible in human subjects but it is a reasonable to assume that sulfuric acid would be more toxic than sulfur dioxide. Current findings in epidemiological studies certainly support this assumption.

    Animals are commonly used to model the human spine for in vitro and in vivo experiments. Many studies have investigated similarities and differences between animals and humans in the lumbar and thoracic vertebrae. However, a quantitative anatomic comparison of calf, pig, and human cervical spines has not been reported. To compare fundamental structural similarities and differences in vertebral bodies from the cervical spines of commonly used experimental animal models and humans. Anatomical morphometric analysis was performed on cervical vertebra specimens harvested from humans and two common large animals (i.e., calves and pigs). Multiple morphometric parameters were directly measured from cervical spine specimens of twelve pigs, twelve calves and twelve human adult cadavers. The following anatomical parameters were measured: vertebral body width (VBW), vertebral body depth (VBD), vertebral body height (VBH), spinal canal width (SCW), spinal canal depth (SCD), pedicle width (PW), pedicle depth (PD), pedicle inclination (PI), dens width (DW), dens depth (DD), total vertebral width (TVW), and total vertebral depth (TVD). The atlantoaxial (C1-2) joint in pigs is similar to that in humans and could serve as a human substitute. The pig cervical spine is highly similar to the human cervical spine, except for two large transverse processes in the anterior regions ofC4-C6. The width and depth of the calf odontoid process were larger than those in humans. VBW and VBD of calf cervical vertebrae were larger than those in humans, but the spinal canal was smaller. Calf C7 was relatively similar to human C7, thus, it may be a good substitute. Pig cervical vertebrae were more suitable human substitutions than calf cervical vertebrae, especially with respect to C1, C2, and C7. The biomechanical properties of nerve vascular anatomy and various segment functions in pig and calf cervical vertebrae must be considered when selecting an animal model for research on the spine.

    2018-01-18

    Little to no correlation has been identified between previous related undergraduate coursework or outcomes on standardized tests and performance in a veterinary curriculum, including anatomy coursework. Therefore, a relatively simplistic method to predict student performance before entrance would be advantageous to many. The purpose of this study was to evaluate whether there is a correlation between performance in a veterinary anatomy pre-course and subsequent performance within a professional anatomy curriculum. Incoming first-year veterinary students at the Louisiana State University School of Veterinary Medicine were asked to participate in a free weeklong pre-course, before the start of the semester. The pre-course covered the musculoskeletal anatomy of the canine thoracic limb using dissection-based methods. Student performance, as evaluated by test grades in the pre-course, did indeed correlate with test grades in professional veterinary anatomy courses. A significant and positive correlation was identified between pre-course final exam performance and performance on examinations in each of 3 professional anatomy courses. Qualitative analyses of student comments pertaining to their experience within the pre-course indicated differences in the perceived benefits of the pre-course between high-, middle-, and low-performing students. These varied perceptions may provide predictive feedback as well as guidance for supporting lower performing students. Together, these results indicate that performance in a weeklong pre-course covering only a small portion of canine anatomy is a strong predictor of performance within a professional anatomy curriculum. In addition, the pre-course differentially affected student perceptions of their learning experience.

  2. Biotecnologia animal

    Full Text Available A biotecnologia animal tem fornecido novas ferramentas para os programas de melhoramento e, dessa forma, contribuído para melhorar a eficiência da produção dos produtos de origem animal. No entanto, os avanços têm sido mais lentos do que antecipados, especialmente em razão da dificuldade na identificação dos genes responsáveis pelas características fenotípicas de interesse zootécnico. Três estratégias principais têm sido utilizadas para identificar esses genes - mapeamento de QTL, genes candidatos e sequenciamento de DNA e mRNA - e cada uma tem suas vantagens e limitações. O mapeamento de QTL permite determinar as regiões genômicas que contêm genes, mas o intervalo de confiança do QTL pode ser grande e conter muitos genes. A estratégia de genes candidatos é limitada por causa do conhecimento ainda restrito das funções de todos os genes. Os sequenciamentos de genomas e de sequências expressas podem auxiliar na identificação da posição de genes e de vias metabólicas associadas à característica de interesse. A integração dessas estratégias por meio do desenvolvimento de programas de bioinformática permitirá a identificação de novos genes de interesse zootécnico. Assim, os programas de melhoramento genético se beneficiarão pela inclusão da informação obtida diretamente do DNA na avaliação do mérito genético dos plantéis disponíveis.Animal biotechnology is providing new tools for animal breeding and genetics and thus contributing to advances in production efficiency and quality of animal products. However, the progress is slower than anticipated, mainly because of the difficulty involved in identifying genes that control phenotypic characteristics of importance to the animal industry. Three main strategies: QTL mapping, candidate genes and DNA and mRNA sequencing have been used to identify genes of economic interest to animal breeding and each has advantages and disadvantages. QTL mapping allows

    Science.gov (United States)

    Graziottin, Alessandra; Gambini, Dania

    2015-01-01

    "Anatomy is destiny": Sigmund Freud viewed human anatomy as a necessary, although not a sufficient, condition for understanding the complexity of human sexual function with a solid biologic basis. The aim of the chapter is to describe women's genital anatomy and physiology, focusing on women's sexual function with a clinically oriented vision. Key points include: embryology, stressing that the "female" is the anatomic "default" program, differentiated into "male" only in the presence of androgens at physiologic levels for the gestational age; sex determination and sex differentiation, describing the interplay between anatomic and endocrine factors; the "clitoral-urethral-vaginal" complex, the most recent anatomy reading of the corpora cavernosa pattern in women; the controversial G spot; the role of the pelvic floor muscles in modulating vaginal receptivity and intercourse feelings, with hyperactivity leading to introital dyspareunia and contributing to provoked vestibulodynia and recurrent postcoital cystitis, whilst lesions during delivery reduce vaginal sensations, genital arousability, and orgasm; innervation, vessels, bones, ligaments; and the physiology of women's sexual response. Attention to physiologic aging focuses on "low-grade inflammation," genital and systemic, with its impact on women sexual function, especially after the menopause, if the woman does not or cannot use hormone replacement therapy. © 2015 Elsevier B.V.

    Accurate reconstruction of the pelvic structures is a most important factor in obtaining a desirable result after anorectoplasty for a patient with anorectal malformation. Preoperative evaluation of the anatomy is indispensable for choosing an appropriate operative method in each case. To facilitate preoperative evaluation, three dimensional animated images of the pelvic structure of patients with anorectal malformations were constructed by computer graphics based upon tomographic images obtained from magnetic resonance imaging. Axial 1-mm thick images of the pelvic portion were generated with spoiling pulse gradient echo sequences using short repetition times (13 msec TR) and short echo times (6 msec TE) with a flip angle of 25 degrees with the patient in the jack-knife position. Graphic data from MR images were transferred to a graphic work station and processed on it. The skin surface, the ano-rectum, the lower urinary tract and the sphincter musculature were segmented by thresholding images by the signal intensity. Three dimensional images were displayed by surface rendering method using the segmented data of each organ and then animation images of these organs were obtained. The anatomy of each type of anomaly was easily recognized by 3-D visualization, and animation of the pelvic viscera and the sphincter musculature made the images more realistic. Animated images of the musculature were especially useful for simulating surgical procedures and could be helpful for reviewing surgical results. (author)

    A number of published articles have suggested that each element of Renaissance art contains an inner meaning. Some of these elements include the choice of theme and protagonists, faces selected for the characters, colors used, species of flowers and trees chosen, animals depicted, positions of the elements, posture of the characters and their gestures, juxtapositions in the scenes, and even the very scenario or landscape. All of these elements are thought to have hidden meanings. In this context, this manuscript presents a new hypothesis suggesting that Michelangelo Buonarroti (1475-1564) may have concealed symbols associated with female anatomy in the ceiling of the Sistine Chapel (painted 1508-1512) in Rome. Thus, this paper is useful to better understand the history of anatomy and corroborates recent descriptions that have suggested the possible existence of anatomic figures concealed in many of Michelangelo's works.

    The medical care currently to brown lemurs (Eulemur fulvus) is limited by a lack of knowledge of their anatomy. The aim of this study was to describe the anatomy and histology and obtain ultrasonographic measurements of normal adrenal glands in these animals. The adrenal glands of four lemurs cadavers were used for the anatomical and histological studies, and those of 15 anesthetized lemurs were examined by ultrasonography. Anatomically, the adrenal glands of brown lemurs are comparable to those of other species. The histological findings showed that the cortex is organized into three distinct layers, whereas most domestic mammals have an additional zone. The surface area of the adrenal glands increased with body weight, and the area of the right adrenal was slightly larger than the left. We suggest using ultrasonography to aid the etiological diagnosis of behavioral abnormalities that might be due to dysfunctions of the adrenal gland. © 2017 John Wiley & Sons A/S.

    The value of behavioral techniques in assessing animal welfare, and in particular assessing the psychological well being of animals, is reviewed. Using cats and horses as examples, 3 behavioral methods are presented: (1) comparison of behavior patterns and time budgets; (2) choice tests; and (3) operant conditioning. The behaviors of intact and declawed cats were compared in order to determine if declawing led to behavioral problems or to a change in personality. Apparently it did not. The behavior of free ranging horses was compared with that of stabled horses. Using two-choice preference tests, the preference of horses for visual contact with other horses and the preference for bedding were determined. Horses show no significant preference for locations from which they can make visual contact with other horses, but they do prefer bedding, especially when lying down. Horses will perform an operant response in order to obtain light in a darkened barn or heat in an outside shed. These same techniques can be used to answer a variety of questions about an animal's motivation for a particular attribute of its environment.

  13. The history of anatomy in Persia

    2007-01-01

    The study of human anatomy can be found throughout the rich history of Persia. For thousands of years, morphological descriptions derived from this part of the world have contributed to and have helped form our current anatomical knowledge base. In this article we review the major influential Persian periods and the individuals who have contributed to the development of anatomy. We have divided the history of Persia into five eras: (1) the period of the Elamites, Medes, early Persians and Babylonians (10th millennium to 6th century BC); (2) following the establishment of the Persian Empire (6th century BC) to the 7th century AD; (3) after the Islamic conquest of Persia to the ascendency of Baghdad (7th to 13th century AD); (4) from the Mongol invasion of Persia to the foundations of modern anatomy (13th to 18th century AD); and (5) modern Persia/Iran (18th century AD to present). Evidence indicates that human dissection was commonplace in the first era, which led to a disciplined practice of surgery in the centuries leading to the foundation of the Persian Empire. By the emergence of Zoroastrianism in the Persian Empire, the microcosm theory was widely used to understand internal anatomy in relation to the external universe. The world's first cosmopolitan university and hospital were built in Gondishapur, south-western Persia, in the third century AD. Greek and Syriac knowledge influenced the second era. With the gradual ruin of Gondishapur and the foundation of Baghdad following the Islamic conquest of Persia (637–651 AD), a great movement took place, which led to the flourishing of the so-called Middle Age or Islamic Golden Age. Of the influential anatomists of this period, Mesue (777–857 AD), Tabbari (838–870 AD), Rhazes (865–925 AD), Joveini (?−983 AD), Ali ibn Abbas (930–994 AD), Avicenna (980–1037 AD) and Jorjani (1042–1137 AD) all hailed from Persia.

    The zebrafish has been shown to be an excellent vertebrate model for studying the roles of specific genes and signaling pathways. The sequencing of its genome and the relative ease with which gene modifications can be performed have led to the creation of numerous human disease models that can be used for testing the potential and the toxicity of new pharmaceutical compounds. Many pharmaceutical companies already use the zebrafish for prescreening purposes. So far, the focus has been on ecotoxicity and the effects on embryonic development, but there is a trend to expand the use of the zebrafish with acute, subchronic, and chronic toxicity studies that are currently still carried out with the more conventional test animals such as rodents. However, before we can fully realize the potential of the zebrafish as an animal model for understanding human development, disease, and toxicology, we must first greatly advance our knowledge of normal zebrafish physiology, anatomy, and histology. To further this knowledge, we describe, in the present article, location and histology of the major zebrafish organ systems with a brief description of their function.

    2000-01-01

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

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

    Berquist, T.H.; Ehman, R.L.; May, G.R.

    1987-01-01

    This book is a guide to the anatomy of extracranial organs as seen in magnetic resonance images. This collection of 96 magnetic resonance images, accompanied by explanatory line drawings, covers all the major organs of the body- shoulder and humerus; elbow and forearm; hand and wrist; chest; abdomen; pelvis; thigh; knee; calf; and ankle. The images are displayed in the axial, coronal, and sagittal planes, enabling radiologists to quickly review coronal and sagittal anatomy as it applies to routine MRI practice. Special emphasis is placed on the extremities, where spatial resolution, coronal and sagittal planes, and soft tissue contrast provide important anatomic detail. Each MRI image is carefully labeled - using numbers with legends at the top of the page - to highlight key anatomic features. Where applicable, special parameters and positioning are noted below the images. Accompanying each image is a line drawing demonstrating the level and plane of the image.

    Today, cycads are a small group of gymnospermous plants with a limited distribution in the (sub)tropics, but they were major constituents of Mesozoic floras. Fossil leaves sporadically found in latest Carboniferous and Permian floras have putatively been ascribed to cycads. However, their true affinity remains unclear due to the lack of anatomical evidence. Virtually all modern cycads have pinnate leaves, but this type of leaf morphology is by no means unique for cycads. Pinnate leaves of Plagiozamites oblongifolius Halle 1927 with well-preserved cuticles showing the epidermal anatomy are here described from the upper Permian Xuanwei Formation of Yunnan Province, Southwest China. The cuticles show a clear differentiation into costal and intercostal zones; stomata are confined to the intercostal zones on both the upper and lower leaf surfaces. The external morphology and the epidermal anatomy of these fossil leaves are closely comparable with those of extant cycads, particularly members of the family Zamiaceae. PMID:29093177

    The interest in the physical perfection and the corporal forms brings as a result the creation of new anatomical studies. The anatomical knowledge progressed in the second half of the XV century, conceiving the knowledge of the human body as a basic reality of Medicine. One of the greater contributions of the Italian Universities to medicine was the teaching of anatomy. The Universities of Padua, Bologna, and Pisa educated in their classrooms great physicians like Andres Vesalio, Gabriel Fallopio, Realdo Colombo, Mondino de Luzzi, Julio Ceasar Aranzio, and Gaspare Tagliacozzi, among others. The teaching of anatomy during the Renaissance was characterized by the development of dissection techniques and autopsy practice, which was recognized as an extremely valuable skill for anatomical study. The dissections were made in circular amphitheatres in the following way: a Medicine professor read the text book, another one made the dissection, and a third one indicated the structures referred.

    Today, cycads are a small group of gymnospermous plants with a limited distribution in the (sub)tropics, but they were major constituents of Mesozoic floras. Fossil leaves sporadically found in latest Carboniferous and Permian floras have putatively been ascribed to cycads. However, their true affinity remains unclear due to the lack of anatomical evidence. Virtually all modern cycads have pinnate leaves, but this type of leaf morphology is by no means unique for cycads. Pinnate leaves of Plagiozamites oblongifolius Halle 1927 with well-preserved cuticles showing the epidermal anatomy are here described from the upper Permian Xuanwei Formation of Yunnan Province, Southwest China.

    Although all the imaging studies in this pictorial essay were done for maternal rather than fetal indications, fetal anatomy was well visualized. However, when scans are undertaken for fetal indications, fetal motion in between scout views and imaging sequences may make specific image planes difficult to obtain. Of the different techniques described in this review, we preferred the HASTE technique and use it almost exclusively for scanning pregnant patients. The T2-weighting is ideal for delineating fetal organs. Also, the HASTE technique allows images to be obtained in 430 msec, limiting artifacts arising from maternal and fetal motion. MR imaging should play a more important role in evaluating equivocal sonographic cases as fast scanning techniques are more widely used. Obstetric MR imaging no longer will be limited by fetal motion artifacts. When complex anatomy requires definition in a complicated pregnant patient, MR imaging should be considered as a useful adjunct to sonography.

  3. Alterations in physiology and anatomy during pregnancy.

    Pregnant women undergo profound anatomical and physiological changes so that they can cope with the increased physical and metabolic demands of their pregnancies. The cardiovascular, respiratory, haematological, renal, gastrointestinal and endocrine systems all undergo important physiological alterations and adaptations needed to allow development of the fetus and to allow the mother and fetus to survive the demands of childbirth. Such alterations in anatomy and physiology may cause difficulties in interpreting signs, symptoms, and biochemical investigations, making the clinical assessment of a pregnant woman inevitably confusing but challenging. Understanding these changes is important for every practicing obstetrician, as the pathological deviations from the normal physiological alterations may not be clear-cut until an adverse outcome has resulted. Only with a sound knowledge of the physiology and anatomy changes can the care of an obstetric parturient be safely optimized for a better maternal and fetal outcome. Copyright © 2013 Elsevier Ltd.

    Yabuki, Yoshihiko

    2016-05-01

    The 1998 edition of Terminologia Anatomica introduced some currently used clinical anatomical terms for the pelvic connective tissue or subserous layer. These innovations persuaded the present author to consider a format in which the clinical anatomical terms could be reconciled with those of gross anatomy and incorporated into a single anatomical glossary without contradiction or ambiguity. Specific studies on the subserous layer were undertaken on 79 Japanese women who had undergone surgery for uterine cervical cancer, and on 26 female cadavers that were dissected, 17 being formalin-fixed and 9 fresh. The results were as follows: (a) the subserous layer could be segmentalized by surgical dissection in the perpendicular, horizontal and sagittal planes; (b) the segmentalized subserous layer corresponded to 12 cubes, or ligaments, of minimal dimension that enabled the pelvic organs to be extirpated; (c) each ligament had a three-dimensional (3D) structure comprising craniocaudal, mediolateral, and dorsoventral directions vis-á-vis the pelvic axis; (d) these 3D-structured ligaments were encoded morphologically in order of decreasing length; and (e) using these codes, all the surgical procedures for 19th century to present-day radical hysterectomy could be expressed symbolically. The establishment of clinical anatomical terms, represented symbolically through coding as demonstrated in this article, could provide common ground for amalgamating clinical anatomy with gross anatomy. Consequently, terms in clinical anatomy and gross anatomy could be reconciled and compiled into a single anatomical glossary. © 2015 Wiley Periodicals, Inc.

    Anatomy has traditionally been a cornerstone of medical education, which has been taught via dissection and didactic lectures. The rising prevalence of mobile tablet technology means medical software applications ("apps") play an increasingly important role in medical education. The applications highlighted in this article will aid anatomical educators to identify which are the most useful in clinical, academic, and educational environments. These have been systematically identified by downloading all applications with keywords related to anatomy and then carrying out qualitative assessment. Novel anatomy applications from developers such as Visible Body, 3D4Medical, and Pocket Anatomy allow students to visualize and manipulate complex anatomical structures using detailed 3D models. They often contain additional content including clinical correlations and a range of media from instructional videos to interactive quiz functions. The strength of tablet technology lies in its ability to consolidate and present anatomical information to the user in the most appropriate manner for their learning style. The only question mark remains over the level of detail and accuracy of these applications. Innovative medical educators who embrace tablet technology will find that anatomy applications serve as a useful learning tool when used in conjunction with existing teaching setups.

    2007-04-01

    Medical students and practitioners learn and use a vocabulary originating almost entirely from classical Latin and Greek languages. Previous generations required Latin or Greek prior to medical school, but the current generation does not have such requirements. Anecdotal evidence suggests that understanding Latin or Greek helps students to learn and practitioners to recall otherwise foreign terminology. This study evaluated students' familiarity with Latin and Greek etymologies before and after a gross anatomy course that incorporated etymologies into its curriculum. First-year medical students at Mayo Clinic College of Medicine were taught Latin and Greek etymologies through lectures and handouts during their gross anatomy course. They took a pretest and a posttest before and after the course to assess their understanding of etymologies. In addition, students from all four years of medical school, residents, and staff physicians also took a general etymology quiz to assess their understanding of etymologies. After their gross anatomy course emphasizing etymologies, first-year students scored higher on the posttest than they did on the pretest. First-year students also reported that learning etymologies enhanced anatomy learning, made the experience more enjoyable, and proved to be less difficult than they thought it would be prior to the course. Medical students, residents, and staff physicians scored almost equally on the general etymology quiz and almost equally reported that etymologies enhanced learning and recalling terminology. Medical students, residents, and staff physicians almost equally endorsed incorporating etymologies into medical education. This study provides novel scientific evidence that a basic understanding of Latin and Greek etymologies enhances performance and comfort when learning and using medical terminology.

    2014-01-01

    The adult ulna has a unique bony architecture that has been described in the literature, but, to the best of our knowledge, the ulnar anatomy in children has not been described. We examined 75 anteroposterior (AP) and 64 lateral radiographs (29 were bilateral) of 50, 0.5- to 11-year-old, healthy children's forearms. On AP radiographs, the total ulnar length, the ulnar proximal angle, the ulnar distal angle, and the distance between each angle from the tip of the triceps insertion; and, on lateral radiographs, the ulnar length and bow deviation were measured. The correlation between age and radiographic measurements, differences based on sex, differences compared with adults' measurements, and interobserver/intraobserver reliability were assessed. Age had a very strong/strong positive correlation with length/distance measurements on both AP and lateral radiographs. Only AP ulnar distal angle was significantly different between sexes (females > males). Compared with the adult ulnar studies, the AP proximal angle in children is significantly smaller and the location of this angle is significantly more distal. Interobserver and intraobserver reliability were very good for length/distance measurements on AP and lateral radiographs. The knowledge of pediatric ulnar anatomy could be helpful in the treatment of forearm deformities due to multiple hereditary exostosis and osteogenesis imperfecta, and in the treatment of ulnar fractures, particularly in Monteggia variants, where restoration of the correct forearm anatomy is essential to obtain good clinical and functional results.

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

  13. Kant on anatomy and the status of the life sciences.

    Science.gov (United States)

    Olson, Michael J

    2016-08-01

    This paper contributes to recent interest in Kant's engagement with the life sciences by focusing on one corner of those sciences that has received comparatively little attention: physical and comparative anatomy. By attending to remarks spread across Kant's writings, we gain some insight into Kant's understanding of the disciplinary limitations but also the methodological sophistication of the study of anatomy and physiology. Insofar as Kant highlights anatomy as a paradigmatic science guided by the principle of teleology in the Critique of the Power of Judgment, a more careful study of Kant's discussions of anatomy promises to illuminate some of the obscurities of that text and of his understanding of the life sciences more generally. In the end, it is argued, Kant's ambivalence with regard to anatomy gives way to a pessimistic conclusion about the possibility that anatomy, natural history, and, by extension, the life sciences more generally might one day become true natural sciences.

    Michelangelo's major interest was the Life of the Soul as expressed in the beautiful structure and movement of the human body, which he often called the "mortal veil" of the divine intentions. This study ascertains Michelangelo's interest in and acquisition of the knowledge of human anatomy, the use of small anatomical models to crystallize his concepts into reality and the application of anatomy to his art. Relatively little is known of this interaction between anatomy and art in Michelangelo's life and work.

    sources, including domain experts, peer-reviewed articles, and reference books, have been used to test the system and to illustrate its potential use in comparative anatomy studies. Results 157 test queries were submitted to the CAIS system, and all of them were correctly answered. The interface was evaluated in terms of clarity and ease of use. This testing determined that the application works well, and is fairly intuitive to use, but users want to see more clarification of the meaning of the different types of possible queries. Some of the interface issues will naturally be resolved as we refine our conceptual model to deal with partial and complex homologies in the content. Conclusions The CAIS system and its associated methods are expected to be useful to biologists and translational medicine researchers. Possible applications range from supporting theoretical work in clarifying and modeling ontogenetic, physiological, pathological, and evolutionary transformations, to concrete techniques for improving the analysis of genotype–phenotype relationships among various animal models in support of a wide array of clinical and scientific initiatives.

    2015-09-01

    "All animals are equal, but some are more equal than others" was the illustrious quote derived from British writer George Orwell's famed work, Animal Farm. Extending beyond the remit of political allegory, however, this statement would appear to hold true for the selection of appropriate animal models to simulate human physiology in preclinical studies. There remain definite gaps in our current knowledge with respect to animal physiology, notably those of intra- and inter-species differences in gastrointestinal (GI) function, which may affect oral drug delivery and absorption. Factors such as cost and availability have often influenced the choice of animal species without clear justification for their similarity to humans, and lack of standardization in techniques employed in past studies using various animals may also have contributed to the generation of contradictory results. As it stands, attempts to identify a single animal species as appropriately representative of human physiology and which may able to adequately simulate human in vivo conditions are limited. In this review, we have compiled and critically reviewed data from numerous studies of GI anatomy and physiology of various animal species commonly used in drug delivery modeling, commenting on the appropriateness of these animals for in vivo comparison and extrapolation to humans. © 2015 Wiley Periodicals, Inc. and the American Pharmacists Association.

    An interventional cohort comparison study with pretesting and post-testing in semesters 1 and 2 was undertaken of 159 medical students in year 3 of the MMBS course at the University of Adelaide in 2010. The intervention comprised the provision of a number of additional online resources in semester 2. Students' views on online anatomy were also sought by a questionnaire delivered at the end of semesters 1 and 2 and via a small focus group at the end of the study. Anatomy assessment results after the introduction of online anatomy were compared with a total of three control semesters in 2009 and 2010. There was >90% broad agreement before the intervention that wet specimens, tutors and discussions with other students helped students learn anatomy. After the intervention, these views remained, but there was additionally >90% broad agreement that text books helped them learn anatomy, that they had good access to anatomical specimens, and there was less agreement that lectures helped. The intervention left students' views on online anatomy largely unchanged and made no significant difference to summative assessment scores. Focus group discussions revealed that students want anatomy tutors to help direct them to reputable and relevant sites. The provision of more online resources in anatomy did not affect student views or learning outcomes. While students may need help from tutors in selecting appropriate online resources, wet specimens, textbooks, and discussions with tutors and other students remain the preferred means of learning anatomy.

  3. Teaching medical anatomy: what is the role of imaging today?

    Science.gov (United States)

    2016-03-01

    Medical anatomy instruction has been an important issue of debate for many years and imaging anatomy has become an increasingly important component in the field, the role of which has not yet been clearly defined. The aim of the paper was to assess the current deployment of medical imaging in the teaching of anatomy by means of a review of the literature. A systematic search was performed using the electronic database PubMed, ScienceDirect and various publisher databases, with combinations of the relevant MeSH terms. A manual research was added. In most academic curricula, imaging anatomy has been integrated as a part of anatomical education, taught using a very wide variety of strategies. Considerable variation in the time allocation, content and delivery of medical imaging in teaching human anatomy was identified. Given this considerable variation, an objective assessment remains quite difficult. In most publications, students' perceptions regarding anatomical courses including imaging anatomy were investigated by means of questionnaires and, regardless of the method of teaching, it was globally concluded that imaging anatomy enhanced the quality and efficiency of instruction in human anatomy. More objective evaluation based on an increase in students' performance on course examinations or on specific tests performed before and after teaching sessions showed positive results in numerous cases, while mixed results were also indicated by other studies. A relative standardization could be useful in improving the teaching of imaging anatomy, to facilitate its assessment and reinforce its effectiveness.

  4. The use of real time ultrasound scanning as a teaching method of anatomy in an undergraduate sonography and medical imaging degree in an Australian university

    International Nuclear Information System (INIS)

    Bowman, A.; Lawson, C.; McKillup, S.

    2016-01-01

    Background: Real-time ultrasound scanning is increasing in popularity as a teaching tool for human anatomy because it is non-invasive, offers real-time 3-D anatomy and is cheaper than dissections. Aim: To assess real-time ultrasound scanning as a teaching method of human anatomy, and to determine what teaching methods medical imaging and sonography students consider effective for understanding human anatomy. Method: Surveys were distributed to two consecutive cohorts of first year medical imaging and medical sonography students at CQUniversity. Participation was voluntary. Comparisons among teaching methods were made using repeated measures ANOVA. Results: Real-time ultrasound scanning was the most preferred method of delivery for anatomy classes overall especially compared to computer programs, videos, 3-D radiological images and dissection. Specifically, students indicated that ultrasound scanning was the preferred method to encourage learning from experience (F 7,231  = 2.942, p = 0.006), to develop team skills (F 7,231  = 4.550, p < 0.006), to follow complex instructions (F 7,231  = 4.656 p < 0.001) and to appreciate anatomical variation (F 7,231  = 2.067, p = 0.048). Dissection was the least favoured teaching method. Conclusion: Real-time ultrasound scanning is a useful tool for teaching anatomy, and animal dissections are a poor substitute for the use of human cadavers. - Highlights: • Real-time ultrasound scanning is a valid teaching tool for human anatomy. • Real-time ultrasound is preferred by students compared to other teaching methods. • Dissection is the least favoured method to learn anatomy. • Ultrasound encourages learning from experience and develops team skills.

    2017-04-01

    The aims of this study were to describe the anatomy of the mouth and pharynx of the pampas deer, and to consider its evolutionary feeding niche according to those characteristics. Gross dissections of the mouth and pharynx were performed in 15 animals, 10 adult females and five young animals under 1 year (three males and two females), all dead by causes unrelated to this anatomical region. The upper lip entered in the constitution of a pigmented nasolabial plane. The masseter muscles weighed 43.8 ± 3.5 g and represented 0.23% of body weight, which corresponds to ruminants of feeders intermediate to grazers and browsers. Parotid glands represented 0.08% of the body weight, characteristic that also categorize the pampas deer as belonging to the intermediate feeding group. The dental formula was the same of the domestic ruminants. The upper incisors and canines were absent, and instead of them, there was a dental pad (Pulvinus dentalis). The upper canine teeth were present only in the deciduous dentition. The existence of a brachydont dentition turns Ozotoceros very vulnerable to continuous use as there is no compensatory teeth growth. The particular anatomy of the mouth and lips of this animal was adapted to a very selective feeding, taking highly nutritious sprouts beyond plant category. In conclusion and in addition to previous studies of anatomy of the digestive organs in this species, pampas deer may be categorized as belonging to the intermediate type of feeding. © 2016 Blackwell Verlag GmbH.

    2004-07-01

    Certain areas of the body contain structures that are difficult to envision in their proper spatial orientations and whose functions are complex and difficult to grasp. This is especially true in the head, where many structures are relatively small and inaccessible. To address this problem, we are designing Web-based programs that consist of high-resolution interactive bitmap illustrations, prepared using Adobe Photoshop, and vector-based animations, prepared via Macromedia Flash. Flash action script language is used for the animations. We have used this approach to prepare a program on the pterygopalatine fossa, an important neurovascular junction in the deep face that is especially difficult to approach by dissection and to depict in static images in an atlas. The program can be viewed online at http://cds.osr.columbia.edu/anatomy/ppfossa/. A table of contents simplifies navigation through the program and a menu enables the user to identify each of the vascular and neuronal components and either to insert or to remove each from its position in the fossa. The functional anatomy of the nerves in the fossa is animated. For example, users can activate and subsequently follow action potentials as they course along axons to their targets. This high degree of interactivity helps promote learning.

    Frederick Ruysch was one of the most prominent Dutch physicians of the seventeenth and eighteenth centuries. For more than 65 years, he was the Praelector Anatomiae (Lecturer of Anatomy) of the Amsterdam Guild of Surgeons. During his career, he conducted many dissections at the guild's theatre to teach anatomy. Ruysch was internationally renowned for his great dissection skills and his innovative techniques for preserving anatomical specimens. The "Anatomy Lesson of Dr. Frederik Ruysch" painted in 1670, is thought to be a group portrait undertaken to commemorate the officials of the Guild of Surgeons. Ruysch was portrayed performing an anatomical dissection of inguinal lymph nodes on the corpse of an executed criminal. This portrait is one of the earliest paintings focusing on the "lymphatic system." We investigated the medical background of the painting by revisiting Ruysch's original work from the mid-seventeenth century. His contributions to the early history of "lymphatic anatomy" are assessed and interpreted from the perspective of the renewed interest in "lymphatic imaging" today. Frederik Ruysch should be considered one of the pioneers contributing to the early knowledge of the lymphatic system. He succeeded in dissecting the lymphatic vessels and valves with the aid of his innovative dissection and preservation techniques. The famous group portrait of the Amsterdam Guild of Surgeons with Ruysch demonstrating the lymph nodes pays tribute to his work on which we still rely today.

    Reproductive tracts of four male Arabian oryx (Oryx leucoryx) from Shaumari Nature Reserve in Jordan were examined to characterize their reproductive anatomy. Animals were allocated into two groups based on their age: Group 1 (n = 2, males were 12 and 14 mo old) and Group 2 (n = 2, males were 7 and 9 yrs old). Observations regarding the morphology, position and orientation of different reproductive organs were made. The external and internal genital organs of male oryx were similar to other domestic ruminant species with minor differences. Copyright © 2012 Elsevier Inc. All rights reserved.

    To investigate the role of ischemia in the pathogenesis of small bowel strictures. Vascular anatomy of 39 small bowel strictures was studied using modified Spalteholtz method. Ten normal small bowel segments were studied as controls. 71.8% of small bowel strictures showed block in the mesenteric vessels (p=0.008). Subset analysis of tuberculous strictures showed block in the mesenteric vessels in 70.8% of strictures (p=0.0098). Ischemia plays a significant role in the pathogenesis of small bowel strictures. Mesenteric vasculopathy has a significant association with tuberculous strictures of the intestine.

    The subscapularis is the largest and most powerful of the rotator cuff muscles and fulfills an important role in glenohumeral movement and stability. The spectrum and implications of subscapularis muscle or tendon injury differ from injury to other rotator cuff components because of its unique structure and function. Diagnosing subscapularis injury is clinically difficult and assessment of subscapularis integrity may be limited during arthroscopy or open surgery. Diagnostic imaging plays an important part in diagnosing and evaluating the extent of subscapularis injury. The radiologist should be aware of the anatomy of the subscapularis, the variations in muscle or tendon injury, and the potential implications for treatment and prognosis. (orig.)

    2017-08-01

    Understanding the anatomic relationship of the pelvic floor muscles with the pelvic girdle, spine, and hips aids the rehabilitation provider in diagnosis, management, and appropriate referrals. The bony anatomy of the pelvic girdle consists of 3 bones and 3 joints. The pelvic floor muscles are comprised mainly of the levator ani muscles with somatic innervation from the lumbosacral plexus. The bony and muscular pelvis is highly interconnected to the hip and gluteal musculature, which together provide support to the internal organs and core muscles. Pelvic floor physiology is centered on bladder and bowel control, sexual functioning, and pregnancy. Copyright © 2017 Elsevier Inc. All rights reserved.

    The dorsal compartment of the forearm contains nine muscles: four belong to the superficial group (extensor digitorum communis, extensor digiti minimi, extensor carpi ulnaris and anconeus) and five to the deep group (supinator, abductor longus, extensor pollicis brevis, extensor pollicis longus, and extensor indices). Of these nine muscles the following details are considered: origin, course, distal insertion and their anatomical connection with those structures which are most often affected by pathologies. The radiologist must have a thorough knowledge of this complex topographic anatomy in order to perform ultrasound (US) and magnetic resonance imaging (MRI) examinations and correctly interpret the images.

    The history of urologic lymphadenectomy is rich and diverse. Our current understanding of its use and benefits is a product of the hard work of numerous physicians and scientists from many nations. Standard dissection templates for the various urologic malignancies are based on a complete understanding of the anatomy of the lymphatic system, which has developed immensely since Hippocrates first described the white blood of the lymphatic system while performing an axillary dissection. It is hoped that the next 100 years will bring even greater comprehension of its value and utility. Copyright © 2011 Elsevier Inc. All rights reserved.

    The fascicular anatomy of the psoas major was determined by dissection in three cadavers. Its actions on the lumbar spine in the sagittal plane were modelled on erect, flexion, and extension radiographs of ten adult males. Calculations revealed that psoas exerts only very small moments that tend to extend the upper lumbar spine and to flex the lower lumbar spine, but at maximum contraction the psoas exerts severe compression forces on the lumbar segments, and large shear forces.

    Experimental work on the functional anatomy of the shoulder has involved a study of the conditions involved in elevation of the arm. Movements of the upper limb are organised round a very special alignment of the scapulo-humeral joint whose geometric features and exact position have been determined. The ligaments of the joint play a major role in the controlling the attainment of this alignment. The value of this alignment in the physiology of the shoulder is demonstrated. A new terminology of shoulder movement is suggested.

  10. Teaching Anatomy in the XXI Century: New Aspects and Pitfalls

    Directory of Open Access Journals (Sweden)

    Veronica Papa

    2013-01-01

    Full Text Available Anatomy has historically been a cornerstone in medical education regardless of nation, racial background, or medical school system. By learning gross anatomy, medical students get a first “impression” about the structure of the human body which is the basis for understanding pathologic and clinical problems. Although the importance of teaching anatomy to both undergraduate and postgraduate students remains undisputed, there is currently a relevant debate concerning methods of anatomy teaching. In the past century, dissection and lectures were its sole pedagogy worldwide. Recently, the time allocated for anatomy teaching was dramatically reduced to such an extent that some suggest that it has fallen below an adequate standard. Traditional anatomy education based on topographical structural anatomy taught in lectures and gross dissection classes has been replaced by a multiple range of study modules, including problem-based learning, plastic models or computer-assisted learning, and curricula integration. “Does the anatomical theatre still have a place in medical education?” And “what is the problem with anatomic specimens?” We endeavor to answer both of these questions and to contribute to the debate on the current situation in undergraduate and graduate anatomy education.

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

    2016-07-01

    The aim of this review was to present an overview, based on a literature search, of surgical anatomy for distal biceps tendon repairs, based on the current literature. A narrative review was performed using Pubmed/Medline using key words: Search terms were distal biceps, insertional, and anatomy. Last decade, the interest in both reconstruction techniques, as well as surgical anatomy of the distal biceps tendon, has increased. The insights into various aspects of distal biceps tendon anatomy (two tendons, bicipital tuberosity, lacertus fibrosis, bicipital-radial bursa, posterior interosseous nerve, and lateral antebrachial cutaneous nerve) have evolved significantly in the last years. Thorough knowledge of the anatomy is essential for the surgeon in order to understand the biomechanics of rupture and reconstruction of the distal biceps tendon and to avoid injuries of the nerves. Some tips and tricks are provided, and some pitfalls were described to avoid complications and optimize surgical outcome. IV.

    Anatomy education is a challenging but vital element in forming future medical professionals. In this work, a personalized and interactive augmented reality system is developed to facilitate education. This system behaves as a "magic mirror" which allows personalized in-situ visualization of anatomy on the user's body. Real-time volume visualization of a CT dataset creates the illusion that the user can look inside their body. The system comprises a RGB-D sensor as a real-time tracking device to detect the user moving in front of a display. In addition, the magic mirror system shows text information, medical images, and 3D models of organs that the user can interact with. Through the participation of 7 clinicians and 72 students, two user studies were designed to respectively assess the precision and acceptability of the magic mirror system for education. The results of the first study demonstrated that the average precision of the augmented reality overlay on the user body was 0.96 cm, while the results of the second study indicate 86.1% approval for the educational value of the magic mirror, and 91.7% approval for the augmented reality capability of displaying organs in three dimensions. The usefulness of this unique type of personalized augmented reality technology has been demonstrated in this paper. © 2015 Wiley Periodicals, Inc.

    2017-05-01

    Virtual Reality is becoming widespread in our society within very different areas, from industry to entertainment. It has many advantages in education as well, since it allows visualizing almost any object or going anywhere in a unique way. We will be focusing on medical education, and more specifically anatomy, where its use is especially interesting because it allows studying any structure of the human body by placing the user inside each one. By allowing virtual immersion in a body structure such as the interior of the cranium, stereoscopic vision goggles make these innovative teaching technologies a powerful tool for training in all areas of health sciences. The aim of this study is to illustrate the teaching potential of applying Virtual Reality in the field of human anatomy, where it can be used as a tool for education in medicine. A Virtual Reality Software was developed as an educational tool. This technological procedure is based entirely on software which will run in stereoscopic goggles to give users the sensation of being in a virtual environment, clearly showing the different bones and foramina which make up the cranium, and accompanied by audio explanations. Throughout the results the structure of the cranium is described in detailed from both inside and out. Importance of an exhaustive morphological knowledge of cranial fossae is further discussed. Application for the design of microsurgery is also commented.

A major disorder of salivary glands is salivary hypofunction and resulting xerostomia, or dry mouth, which affects hundreds of thousands of patients each year who suffer from salivary gland diseases or undergo head and neck cancer treatment. There is currently no curative therapy for these patients. To improve these patients' quality of life, new therapies are being developed based on findings in salivary gland cell and developmental biology. Here we discuss the anatomy and biogenesis of the major human salivary glands and the rodent submandibular gland, which has been used extensively as a research model. We also include a review of recent research on the identification and function of stem cells in salivary glands, and the emerging field of research suggesting that nerves play an instructive role during development and may be essential for adult gland repair and regeneration. Understanding the molecular mechanisms involved in gland biogenesis provides a template for regenerating, repairing or reengineering diseased or damaged adult human salivary glands. We provide an overview of 3 general approaches currently being developed to regenerate damaged salivary tissue, including gene therapy, stem cell-based therapy and tissue engineering. In the future, it may be that a combination of all three will be used to repair, regenerate and reengineer functional salivary glands in patients to increase the secretion of their saliva, the focus of this monograph.

    The vestibular portion of the eighth cranial nerve informs the brain about the linear and angular movements of the head in space and the position of the head with respect to gravity. The termination sites of these eighth nerve afferents define the territory of the vestibular nuclei in the brainstem. (There is also a subset of afferents that project directly to the cerebellum.) This chapter reviews the anatomical organization of the vestibular nuclei, and the anatomy of the pathways from the nuclei to various target areas in the brain. The cytoarchitectonics of the vestibular brainstem are discussed, since these features have been used to distinguish the individual nuclei. The neurochemical phenotype of vestibular neurons and pathways are also summarized because the chemical anatomy of the system contributes to its signal-processing capabilities. Similarly, the morphologic features of short-axon local circuit neurons and long-axon cells with extrinsic projections are described in detail, since these structural attributes of the neurons are critical to their functional potential. Finally, the composition and hodology of the afferent and efferent pathways of the vestibular nuclei are discussed. In sum, this chapter reviews the morphology, chemoanatomy, connectivity, and synaptology of the vestibular nuclei.

    Full Text Available Phlomoides (Lamiaceae: Lamioideae is a species rich, widespread, and taxonomically complex genus. A comparative anatomical study of the petioles and leaf lamina of 17 Phlomoides taxa representing 4 sections of the genus distributed in Iran was carried out to evaluate interspecific relationships and anatomical features that may be useful in species identification and subgeneric classification. The general leaf anatomy of Phlomoides species presented here corroborates earlier studies in Lamiaceae and on a few studied species in the genus. Leaf anatomy provides valuable characters that are useful in subgeneric classification as well as species discrimination in Phlomoides. The most important diagnostic characters are as follows: the shape of transverse section, length of ventral and dorsiventral axis, number of median bundles in the petiole, number of cell layers of palisade and spongy parenchyma, type and thickness of collenchyma as well as trichome type. Based on the present study and in accordance with previous works, some large sections such as Eremostachys appears to be natural, while circumscription of sect. Filipendula should be revised.

    Despite widespread calls for reform in undergraduate science, technology, engineering, and mathematics education, effecting lasting change in instructor practice is challenging to achieve. This article describes the results of a 2-yr research study that involved efforts to develop the pedagogical expertise of a group of anatomy and physiology instructors at the college level. Data were collected through a series of individual interviews that included the use of the Teacher Beliefs Inventory questionnaire (23) along with observations onsite in participants' college classrooms and at process-oriented guided inquiry learning (POGIL) curriculum writing workshops. Findings indicated attitudinal shifts on the part of participants from teacher-centered to more student-centered pedagogy and supported the benefits of long-term professional development for instructors. Here, we documented the successful progress of these professors as they participated in a curriculum development process that emphasized student-centered teaching with the goal of promoting broader change efforts in introductory anatomy and physiology.

    Coronary sinus (CS) anatomy is a major predictor of successful implantation of left ventricular (LV) lead and procedural outcome. We therefore made an attempt to look at the CS anatomy and possible feasibility to classify them into categories depending upon their size, branching pattern, location of posterolateral vein (PLV), and other parameters in order to guide the cardiologist for successful cannulation of the CS and LV lead implantation. We analyzed the levophase angiograms of patients (n = 100) undergoing routine coronary angiography in the right anterior oblique view. We have made an attempt to classify these observations on the basis of predetermined parameters and a working classification was brought out for the ease of the operator and to predict the bottlenecks of the procedure. On the basis of predetermined parameters, venograms obtained from 100 patients were analyzed and findings were divided into three groups depending upon the ease of cannulation of posterolateral vein for LV lead placement. These 3 groups were further classified as type I, type II, and type III coronary sinuses. This observational study proposes a new anatomical working classification for CS for purposes of successful LV lead placement and optimal operative success.

  1. Arthroscopic Anatomy of the Ankle Joint.

    There are a number of variations in the intra-articular anatomy of the ankle which should not be considered pathological under all circumstances. The anteromedial corner of the tibial plafond (between the anterior edge of the tibial plafond and the medial malleolus) can have a notch, void of cartilage and bone. This area can appear degenerative arthroscopically; it is actually a normal variant of the articular surface. The anterior inferior tibiofibular ligament (AITF) can possess a lower, accessory band which can impinge on the anterolateral edge of the talar dome. In some cases it can cause irritation along this area of the talus laterally. If it is creating local irritation it can be removed since it does not provide any additional stabilization to the syndesmosis. There is a beveled region at the anterior leading edge of the lateral and dorsal surfaces of the talus laterally. This triangular region is void of cartilage and subchondral bone. The lack of talar structure in this region allows the lower portion of the AITF ligament to move over the talus during end range dorsiflexion of the ankle, preventing impingement. The variation in talar anatomy for this area should not be considered pathological. Copyright © 2016 Elsevier Inc. All rights reserved.

    Juvenile bovine patients who present with clinical signs of lameness are commonly evaluated using radiographic techniques both within a hospital setting and in a farm environment. The radiographic development of the juvenile bovine skeleton is currently poorly documented. In this study, the limbs of four heifer calves were sequentially radiographed to assess development of the juvenile bovine appendicular skeleton in the first 12 months of life. Images were acquired at three weeks, three months, six months, nine months and one year of age. The normal radiographic anatomy of the fore limbs and hindlimbs and the changes over the first 12 months are described. The majority of physes remain open throughout this period, with the exception of the proximal physes of the proximal and middle phalanges, the proximal radial physis, and the proximal humeral physis which close radiographically between 9 months and 12 months of age, and fusion of the fourth and central tarsal bones occurs between 9 months and 12 months of age. The results of this study may aid in differentiating normal and abnormal anatomy in the juvenile bovine limb. British Veterinary Association.

    The aim of the present work was to see if storytelling in a clinical dental anatomy course would increase student satisfaction. We enhanced teaching by spontaneous storytelling in problem-based learning, in half of the third-year dentistry class. At the end of the course, we administered an anonymous questionnaire to the students in the class, consisting of 12 questions that students had to answer on a Likert scale of 1-5. An overall satisfaction score was obtained and we used a linear mixed model to compare differences in satisfaction between the two groups, with "group" as the fixed effect. We also conducted an exploratory factor analysis of the responses to investigate whether there were distinct constructs within the data. Overall satisfaction is high, with students "with stories" having higher satisfaction than those "without stories." The former group consistently gives higher satisfaction scores, regardless of which question is being asked. Factor analysis provides evidence that storytelling nurtures reflective learning, while students work on their clinical anatomy problems.

    Anatomy professors world over are lamenting about medical students' lack of interest in dissections and its diminishing utilisation in medical studies. The objective of our study was to find out the reasons why some of the Pakistani medical students were avoiding dissections. We conducted this study in 5 medical colleges of Pakistan from Dec 2010-Oct 2011. Questionnaires were prepared and administered to more than 500 Pakistani medical students, at least 6 months after their first cadaver dissecting session. Mostly 1st and 2nd year medical students participated in this study. Around 43% students have actually performed dissections in some form, whereas around 57% had never touched the cadaver. Further evaluation of these results revealed that out of 57% of students, 45% avoided dissection due to bad smell of formaldehyde, 37% due to moral/ethical grounds, 22% due to low motivation and respect of human body, 19.4% due to anxiety, 18.6% due to religious reason, 16% due to fear, asthma and emotional reaction, 9.4% due to toxic chemical, 8.6% due to laziness and 7% due to nightmares. In spite of availability of required number of cadavers in all 5 medical colleges and a clear realisation amongst the students that dissecting cadaver is an effective way of learning anatomy; majority of students were not very keen and had therefore not performed dissection even once.

    Alternatives and/or supplements to animal dissection are being explored by educators of human anatomy at different academic levels. Clay modeling is one such alternative that provides a kinesthetic, three-dimensional, constructive, and sensory approach to learning human anatomy. The present study compared two laboratory techniques, clay modeling of human anatomy and dissection of preserved cat specimens, in the instruction of muscles, peripheral nerves, and blood vessels. Specifically, we examined the effect of each technique on student performance on low-order and high-order questions related to each body system as well as the student-perceived value of each technique. Students who modeled anatomic structures in clay scored significantly higher on low-order questions related to peripheral nerves; scores were comparable between groups for high-order questions on peripheral nerves and for questions on muscles and blood vessels. Likert-scale surveys were used to measure student responses to statements about each laboratory technique. A significantly greater percentage of students in the clay modeling group "agreed" or "strongly agreed" with positive statements about their respective technique. These results indicate that clay modeling and cat dissection are equally effective in achieving student learning outcomes for certain systems in undergraduate human anatomy. Furthermore, clay modeling appears to be the preferred technique based on students' subjective perceptions of value to their learning experience.

    Medical schools at the beginning of Meiji era were diverse, both in regard to their founders and their methods of education, frequently employing foreign teachers of various nationalities. In 1871, German teachers were appointed to organize medical education at the medical school of the University of Tokyo. The anatomical education at the school was conducted by German teachers, i.e. Miller (1871-1873), Dönitz (1873-1877), Gierke (1877-1880) and Disse (1880-1885), followed by Koganei, who returned from the study in Germany. At the first meeting of Japanese Association ofAnatomists in 1893 [Meiji 26], the Japanese anatomy teachers met together and most of them were graduates of the University of Tokyo or fellows of its anatomy department. Before 1877 [Meiji 10], the anatomy books were mainly translated from English books, and foreign teachers of various nationalities were employed in many medical schools in Japan. After 1877 [Meiji 10], the anatomy books based on the lectures by German teachers at the University of Tokyo were published. The anatomy books after 1887 [Meiji 20] were written based on German books, and the German anatomical terms were utilized. After 1905 [Meiji 38], the original Japanese anatomy books appeared, employing international anatomical terms. In the Meiji 10s the anatomy teachers and anatomy textbooks spread from the University of Tokyo to the medical schools in Japan as the number of medical schools increased temporally. In the Meiji 20s the five national and three public medical schools in addition to the University of Tokyo provided substantial anatomy education including dissection course. Even in the early Meiji 20s these medical schools supplied only half of the newly licensed doctors, and the others were supplied through the national examination after preparatory education at private medical schools without opportunity of substantial anatomy education including dissection course.

    Aim To evaluate the structure of the anatomy program in the first year medical curriculum of University of Split School of Medicine by comparing it with the recommendations by the Educational Affairs Committee of the American Association of Clinical Anatomists (AACA) and the Terminologia Anatomica (TA); we also quantitatively evaluated the organization of teaching material in contemporary topographical anatomy textbooks and matched them with the AACA recommendations, TA, and the curriculum of the anatomy course taught at Medical School in Split, Croatia. Methods TA, official recommendations of the AACA, 6 contemporary anatomy textbooks, and the structure of the anatomy course were analyzed for the proportion of the terms or text devoted to standard topographical regions of the body. The findings were correlated using Spearman ρ test. Results The curriculum outline correlated both with the AACA recommendations (Spearman ρ = 0.83, P = 0.015) and TA (Spearman ρ = 0.73, P = 0.046). Textbooks contained 8 distinct sections, 7 allocated to topographic anatomy regions and 1 to general anatomy concepts and principles. The structure of all textbooks correlated significantly with the course curriculum. However, 4 out of 6 textbooks did not correlate with TA and only a single textbook showed significant correlation with the AACA recommendations. Conclusion Anatomy textbooks vary in the amount of text dedicated to different parts of topographical anatomy and are not quite concordant with curriculum recommendations and standard anatomical terminology. Planning the structure of an anatomy course should not be based on a single book or recommendation but on evidence. PMID:19260144

    The study aims to investigate anatomy learning styles and strategies of Jordanian and Malaysian medical students at the Jordan University of Science and Technology. The study is a cross-sectional questionnaire-based study. Students' responses for the questionnaire were numerically coded, and the results were analyzed to reveal statistically significant differences between Jordanian and Malaysian students. The results showed that Jordanian medical students were less interested in using cadavers in learning anatomy than Malaysian medical students. However, similar to their Malaysian counterparts, they prefer to employ other tools to learn anatomy like plastinated models and Internet-based resources. In addition to the aforementioned tools, Malaysian students were more interested in using cross-sectional images and making their own revision cards. Both Jordanian and Malaysian medical students were more interested in learning anatomy through clinical cases, and by system rather than by region. Moreover, it was revealed that Jordanian medical students learn anatomy more efficiently when they formulate a general view of a particular topic. Both Jordanian and Malaysian medical students also relied on reciting definitions and memorizing facts to learn anatomy. The study also reported significant differences between Jordanian and Malaysian students' perspectives on learning anatomy. The findings of the study suggest that Jordanian and Malaysian medical students posses different cultures of learning. Jordanian anatomy instructors need to consider these different learning cultures when they prepare their instructional methods and teaching materials to fulfill the educational needs of their culturally diverse students.

    Over the past century, medical imaging has brought a new revolution: internal anatomy of a patient could be seen without any invasive technique. This revolution has highlighted the two main limits of current anatomy: the anatomical description is physician dependent, and the average anatomy is more and more frequently insufficient to describe anatomical variations. These drawbacks can sometimes be so important that they create mistakes but they can be overcome through the use of 3D patient-specific surgical anatomy. In this article, we propose to illustrate such improvement of standard anatomy on liver. We first propose a general scheme allowing to easily compare the four main liver anatomical descriptions by Takasaki, Goldsmith and Woodburne, Bismuth and Couinaud. From this general scheme we propose four rules to apply in order to correct these initial anatomical definitions. Application of these rules allows to correct usual vascular topological mistakes of standard anatomy. We finally validate such correction on a database of 20 clinical cases compared to the 111 clinical cases of a Couinaud article. Out of the 20 images of the database, we note a revealing difference in 14 cases (70%) on at least one important branch of the portal network. Only six cases (30%) do not present a revealing difference between both labellings. We also show that the right portal fissure location on our 20 cases defined between segment V and VI of our anatomical definition is well correlated with the real position described by Couinaud on 111 cases, knowing that the theoretical position was only found in 46 cases out of 111, i.e., 41.44% of cases with the non-corrected Couinaud definition. We have proposed a new anatomical segmentation of the liver based on four main rules to apply in order to correct topological errors of the four main standard segmentations. Our validation clearly illustrates that this new definition corrects the large amount of mistakes created by the current

    Several factors affect the success of students in college classes. The objective of this research was to determine what factors affect success of undergraduate students in an anatomy and physiology class. Data were collected from 602 students enrolled in the Agriculture and Life Sciences (ALS) 2304 Animal Physiology and Anatomy course from 2005 through 2012. The data set included 476 females (79.1%) and 126 males (20.9%). Time to complete exams was recorded for each student. For statistical analyses, students' majors were animal and poultry sciences (APSC), agricultural sciences, biochemistry, biological sciences, dairy science, and "other," which combined all other majors. All analyses were completed using the GLIMMIX procedure of SAS (SAS Institute Inc., Cary, NC). Gender, major, matriculation year, major by year interaction, gender by year interaction, and time to complete the exam affected final course grade. The significant gender effect was manifested in the final grade percentage of 75.9 ± 0.4 for female students compared with 72.3 ± 0.6 for male students. Junior males had final course grades comparable with those of females, but sophomore and senior males had lower final course grades than other combinations. Biology majors had a final grade of 82.4 ± 0.6 and this grade was greater than all other majors. Students classified as "other" had a final score of 74.4 ± 0.8, which was greater than agricultural science majors (69.5 ± 0.9). The APSC grade (72.6 ± 0.5) was higher than the agricultural science majors. Junior students had significantly greater final grades (76.1 ± 0.5) than sophomores (73.3 ± 0.6) and seniors (72.9 ± 0.9). All biology students had greater final grades than all other majors, but biochemistry juniors had greater final course grades than APSC, agricultural science, and dairy science juniors. "Other" seniors had greater final course grades than agricultural science seniors. The regression for time to complete the exam was

    Background: The adductor magnus (AM) has historically been a potential source of confusion in patients with suspected proximal hamstring avulsion injuries. Purpose: To investigate the anatomic characteristics of the AM, including its osseous origin, anatomic dimensions, and relationship to the proximal hamstring tendons. Study Design: Descriptive laboratory study. Methods: Dissection of the AM origin was performed in 11 (8 cadavers) fresh-frozen hip-to-foot cadaveric hemipelvis specimens. The gross anatomy and architecture of the proximal hamstring and AM tendons were studied. After dissecting the hamstring tendons away from their origin, the dimension, shape, and orientation of the tendon footprints on the ischial tuberosity were determined. Results: The AM was identified in all cadaveric specimens. The mean tendon thickness (anterior to posterior [AP]) was 5.7 ± 2.9 mm. The mean tendon width (medial to lateral [ML]) was 7.1 ± 2.2 mm. The mean tendon length was 13.1 ± 8.7 cm. The mean footprint height (AP dimension) was 12.1 ± 2.9 mm, and mean footprint width (ML dimension) was 17.3 ± 7.1 mm. The mean distance between the AM footprint and the most medial aspect of the conjoint tendon footprint was 8.5 ± 4.2 mm. Tendon measurements demonstrated a considerable degree of both intra- and interspecimen variability. Conclusion: The AM tendon is consistently present just medial to the conjoint tendon at the ischial tuberosity, representing the lateral-most portion of the AM muscle. This study found wide variation in the dimensional characteristics of the AM tendon between specimens. Its shape and location can mimic the appearance of an intact hamstring (conjoint or semimembranosus) tendon intraoperatively or on diagnostic imaging, potentially misleading surgeons and radiologists. Therefore, detailed knowledge of the AM tendon anatomy, footprint anatomy, and its relationship to the hamstring muscle complex is paramount when planning surgical approach and technique

    When one considers the names of those whose affect on dentistry reached far beyond their lifetimes, one may think of Fauchard, Wells, Morton and Black. One name that deserves to be called among the pantheon of the greats is Bartholomaeus Eustachius. Eustachius was not the first to study the anatomy of the teeth and jaws, having been preceded by Da Vinci; however, he was the first to publish a treatise devoted entirely to this subject, Libellus de Dentibus, in 1563. As Sir William Osler, the father of modern medicine, stated: "In Science, the credit goes to the man who convinces the world, not to whom the idea first occurs." The purpose of this paper is to show that Eustachius deserves to be named the father of dental anatomy.

    The purpose of this study was to establish reference values for diagnostic ophthalmic tests in sambar deer (Rusa unicolor) as well as to describe the most relevant features of the bony orbital anatomy and ocular histology. Twenty healthy animals, free living in a forest reserve, that were captured for clinical evaluation as part of a health survey were evaluated. Schirmer tear test-1 (STT1), conjunctival microbiota, intraocular pressure (IOP), conjunctival cytology, anatomy of the bony orbit, and ocular histology were studied. Mean ± SD STT1 and IOP values were 18.8 ± 4.7 mm and 11.4 ± 2.8 mmHg, respectively. IOP was significantly higher in adult (4-8 years) animals (P = 0.04). Bacterial growth was present in 100% of the samples, with a prevalence for Staphylococcus sp. and Bacillus sp. The conjunctival cytology revealed predominance of columnar epithelial cells with mild pigmentation. The sambar deer orbit is completely encompassed by bone. The ocular histology was very similar to most mammalians. The findings in this study will be useful in the diagnosis of ocular diseases in Rusa unicolor. © 2014 American College of Veterinary Ophthalmologists.

    There is ongoing debate in paleoanthropology about whether and how the anatomy of the cranium, and especially the cranial base, is evolving in response to locomotor and postural changes. However, the majority of studies focus on two-dimensional data, which fails to capture the complexity of cranial anatomy. This study tests whether three-dimensional cranial base anatomy is linked to locomotion or to other factors in primates (n = 473) and marsupials (n = 231). Results indicate that although there is a small effect of locomotion on cranial base anatomy in primates, this is not the case in marsupials. Instead, facial anatomy likely drives variation in cranial base anatomy in both primates and marsupials, with additional roles for body size and brain size. Although some changes to foramen magnum position and orientation are phylogenetically useful among the hominoids, they do not necessarily reflect locomotion or positional behavior. The interplay between locomotion, posture, and facial anatomy in primates requires further investigation. Copyright © 2017 Elsevier Ltd. All rights reserved.

    Dental CT software program can provide reformatted cross-sectional and panoramic images that cannot be obtained with conventional axial and direct coronal CT scan. The purpose of this study is to describe the method of the technique and to identify the precise anatomy of jaw. We evaluated 13 mandibles and 7 maxillae of 15 subjects without bony disease who were being considered for endosseous dental implants. Reformatted images obtained by the use of bone algorithm performed on GE HiSpeed Advantage CT scanner were retrospectively reviewed for detailed anatomy of jaw. Anatomy related to neurovascular bundle(mandibular foramen, inferior alveolar canal, mental foramen, canal for incisive artery, nutrient canal, lingual foramen and mylohyoid groove), muscular insertion(mylohyoid line, superior and inferior genial tubercle and digastric fossa) and other anatomy(submandibular fossa, sublingual fossa, contour of alveolar process, oblique line, retromolar fossa, temporal crest and retromolar triangle) were well delineated in mandible. In maxilla, anatomy related to neurovascular bundle(greater palatine foramen and groove, nasopalatine canal and incisive foramen) and other anatomy(alveolar process, maxillary sinus and nasal fossa) were also well delineated. Reformatted images using dental CT software program provided excellent delineation of the jaw anatomy. Therefore, dental CT software program can play an important role in the preoperative assessment of mandible and maxilla for dental implants and other surgical conditions

    2017-06-01

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

  19. Anatomy in the Third Reich: an outline, part 3. The science and ethics of anatomy in National Socialist Germany and postwar consequences.

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

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

    Macaque monkeys are used in many research applications, including cerebrovascular investigations. However, detailed catalogs of the relevant vascular anatomy are scarce. We present our experience with macaque vessel patterns as determined by digital subtraction angiography of 34 different monkeys. We retrospectively analyzed digital subtraction angiograms obtained during experimental internal carotid artery (ICA) catheterization and subsequent injection of 1-methyl 4-phenyl 1,2,3,6-tetrahydropyridine. Results were catalogued according to vascular distribution and variants observed. Macaque monkeys have a bovine aortic arch. The carotid vessels generally bifurcate, but are occasionally observed to divide into three vessels. The external carotid gives rise primarily to two trunks: an occipital branch and a common vessel that subsequently gives off the lingual, facial, and superior thyroid arteries. The internal maxillary artery may be present as a terminal branch of the external carotid or as a branch of the occipital artery. The ICA is similar in course to that of the human. The anterior circle of Willis was intact in all monkeys in our study. Its primary difference from that of the human is the union of the bilateral anterior cerebral arteries as a single (azygous) median vessel. Macaque cervical carotid and circle of Willis arterial anatomy differs from humans in a couple of specific patterns. Knowledge of these differences and similarities between human and macaque anatomy is important in developing endovascular macaque models of human diseases, such as ischemic stroke.

    Do non‐human animals have rights? The answer to this question depends on whether animals have morally relevant mental properties. Mindreading is the human activity of ascribing mental states to other organisms. Current knowledge about the evolution and cognitive structure of mindreading indicates that human ascriptions of mental states to non‐human animals are very inaccurate. The accuracy of human mindreading can be improved with the help of scientific studies of animal minds. However, the s...

Furthermore, it prohibits and imposes sanctions for any treatment that causes animals unnecessary suffering. The present st...

  4. Perception of medical students towards the clinical relevance of anatomy.

    2007-07-01

    Recent developments worldwide in medical curricula have often led to major cuts in the teaching of human anatomy. Indeed, it is perceived by some that gross (topographical) anatomy has an exaggerated importance in the initial training of doctors. The value of anatomy consequently has frequently been considerably diminished within medical curricula that have reduced factual content. To date, however, there have been no objective studies into the perceived relevance of anatomy to clinical medicine that have aimed to quantify the attitudes of medical students. On the basis of responses to an attitude analysis questionnaire devised according to the precepts of Thurstone and Chave (The Measurement of Attitude: A Psychophysical Method and Some Experiments with a Scale for Measuring Attitude Toward the Church. Chicago, IL: University of Chicago Press, 1951), we investigated the perception of medical students at Cardiff and Paris towards the importance of gross anatomy to clinical medicine. This was undertaken during the early stages of their studies (when they were newly-admitted to university and were about to commence anatomy courses), immediately after finishing their anatomy courses, and later in the final year of medical studies. The results suggest that, even where there might be geopolitical and cultural backgrounds, students at all stages of their medical course share with professional anatomists the view that anatomy is a very important subject for their clinical studies. Thus, contrary to the unquantified beliefs of those who are sceptical about the purpose and value of anatomy in an undergraduate medical curriculum, the students themselves do not appear to share such beliefs.

    The distal radioulnar joint allows the human to rotate the forearm to place the hand in a desired position to perform different tasks, without interfering with the grasping function of the hand. The ulna is the stable part of the forearm around which the radius rotates; the stability of the distal radioulnar joint is provided by the interaction between ligaments, muscles and bones. The stabilizing structures are the triangular fibrocartilage complex, the ulnocarpal ligament complex, the extensor carpi ulnaris tendon and tendon sheath, the pronator quadratus, the interosseous membrane and ligament, the bone itself and the joint capsule. The purpose of this review article is to present and illustrate the current understanding of the functional anatomy and pathomechanics of this joint.

  6. Scapulothoracic Anatomy and Snapping Scapula Syndrome

    2013-01-01

    Full Text Available The scapulothoracic articulation is a sliding junction between the deep aspect of the scapula and thoracic rib cage at the levels of ribs 2 through 7. Motion at this articulation is dynamically stabilized by a variety of muscular attachments, allowing for controlled positioning of the glenoid to assist in glenohumeral joint function. A thorough understanding of the complex anatomic relationships, including the various muscles, and bursa, is critical to the evaluation of patients presenting with scapulothoracic disorders. The snapping scapula syndrome is caused by either osseous lesions or scapulothoracic bursitis and can be difficult to recognize and treat. The purpose of this review is to discuss the anatomy of the scapulothoracic articulation with an emphasis on the pathology associated with snapping scapula syndrome.

    2017-10-01

    Fecal incontinence is a devastating condition that has a severe impact on quality of life. This condition disproportionately affects women and its incidence is increasing with the aging United States population. Fecal continence is maintained by coordination of a functioning anal sphincter complex, intact sensation of the anorectum, rectal compliance, and the ability to consciously control defecation. Particularly important are the puborectalis sling of the levator ani muscle complex and intact innervation of the central and peripheral nervous systems. An understanding of the intricate anatomy required to maintain continence and regulate defecation will help clinicians to provide appropriate medical and surgical management and diminish the negative impact of fecal incontinence. In this article, we describe the anatomic and neural basis of fecal continence and normal defecation as well as changes that occur with fecal incontinence in women. Clin.

    2013-09-01

    Full Text Available From the first shoulder arthroscopy performed on a cadaver in 1931, shoulder arthroscopy has grown tremendously in its ability to diagnose and treat pathologic conditions about the shoulder. Despite improvements in arthroscopic techniques and instrumentation, it is only recently that arthroscopists have begun to explore precise anatomical structures within the subdeltoid space. By way of a thorough bursectomy of the subdeltoid region, meticulous hemostasis, and the reciprocal use of posterior and lateral viewing portals, one can identify a myriad of pertinent ligamentous, musculotendinous, osseous, and neurovascular structures. For the purposes of this review, the subdeltoid space has been compartmentalized into lateral, medial, anterior, and posterior regions. Being able to identify pertinent structures in the subdeltoid space will provide shoulder arthroscopists with the requisite foundation in core anatomy that will be required for challenging procedures such as arthroscopic subscapularis mobilization and repair, biceps tenodesis, subcoracoid decompression, suprascapular nerve decompression, quadrangular space decompression and repair of massive rotator cuff tears.

    Full Text Available Anatomy of curriculum is described as the components that must be present in every curriculum that can be used for the learning process. They are objectives of the curriculum, materials of teaching, contents of the curriculum, strategies or methods, media and evaluation and improvement of teaching. These components are interconnected to one another. Each component has a content which is very important for the continuity of the curriculum. One of the most important parts of the curriculum is procces of learning as an empowering or enable the students. Thus, the need for active and participatory interaction between students and academic material or with a certain situation so that matter can be transformed into the learning experience of students.

    The advent of social media and microblogging platforms has radically changed the way we consume information and form opinions. In this paper, we explore the anatomy of the information space on Facebook by characterizing on a global scale the news consumption patterns of 376 million users over a time span of 6 y (January 2010 to December 2015). We find that users tend to focus on a limited set of pages, producing a sharp community structure among news outlets. We also find that the preferences of users and news providers differ. By tracking how Facebook pages "like" each other and examining their geolocation, we find that news providers are more geographically confined than users. We devise a simple model of selective exposure that reproduces the observed connectivity patterns.

    2013-02-01

    Understanding normal anatomy of the hip is important for diagnosing its pathology. MR arthrography is more sensitive for the detection of intra-articular pathology than noncontrast MR imaging. Important elements of the osseous structures on MR imaging include the alignment and the marrow. Acetabular ossicles may be present. Normal variations involving the cartilage include the supra-acetabular fossa and the stellate lesion. Important muscles of the hip are the sartorius, rectus femoris, iliopsoas, gluteus minimus and medius, adductors, and hamstrings. The iliofemoral, ischiofemoral, and pubofemoral ligaments represent thickenings of the joint capsule that reinforce and stabilize the hip joint. Normal variations in the labrum include labral sulcus and absent labrum. The largest nerves in the hip and thigh are the sciatic nerve, the femoral nerve, and the obturator nerve.

    Hundreds of thousands of laboratory animals are being used every year for scientific experiments held in Israel, mostly mice, rats, rabbits, guinea pigs, and a few sheep, cattle, pigs, cats, dogs, and even a few dozen monkeys. In addition to the animals sacrificed to promote scientific research, millions of animals slain every year for other purposes such as meat and fine leather fashion industries. While opening a front against all is an impossible and perhaps an unjustified task, the state of Israel enacted the Animal Welfare (Animal Experimentation) Law (1994). The law aims to regulate scientific animal experiments and to find the appropriate balance between the need to continue to perform animal experiments for the advancement of research and medicine, and at the same time to avoid unnecessary trials and minimize animal suffering. Among other issues the law deals with the phylogenetic scale according to which experimental animals should be selected, experiments for teaching and practicing, and experiments for the cosmetic industry. This article discusses bioethics considerations in animal experiments as well as the criticism on the scientific validity of such experiments. It further deals with the vitality of animal studies and the moral and legal obligation to prevent suffering from laboratory animals.

    To determine the regional thickness variation of the interosseous membrane (IOM) along the forearm and validate magnetic resonance imaging of the IOM with laser micrometry. Axial thickness measurements of 12 cadaver forearms were obtained using magnetic resonance imaging (MRI) at radial, central, and ulnar locations. The specimens were dissected, and IOM thickness measured using a laser micrometer. MRI and laser measurements of the main and oblique IOM bundles were compared. An axial thickness profile was plotted versus forearm length, and radial, central, and ulnar positions were compared. The main bundle thickness was 2.18±0.20 mm using laser micrometry, which was not significantly different from MRI measurements (1.86±0.25 mm, p=0.11, power = 0.84). The dorsal oblique bundle thickness was not significantly different between measurement methods (2.93±0.77 mm and 3.30±1.64 mm using laser micrometry and MRI respectively, p=0.75, power = 0.04). Both methods demonstrated a progressive increase in thickness proximally within the forearm. MRI measurements demonstrated a significantly greater thickness increase in the radial location compared to the central location (slope = 2.26 and 1.05, r 2 =0.31 and 0.12 respectively, p 2 =0.02, p>0.05). Our findings describe the varying IOM anatomy using MRI, and determined the location of the clinically important IOM fiber bundles. This study confirms the accuracy of MR imaging of the IOM by comparison with a laser micrometer, and demonstrates the thickness variation along the forearm. This information may be used to identify changes in IOM anatomy with both acute IOM injury and chronic fiber attenuation. (orig.)

    Abstract Purpose Achondroplasia is the most common form of skeletal dysplasia, affecting more than 250 000 individuals worldwide. In these patients, the developing knee undergoes multiple anatomical changes. The purpose of this study was to characterise the intra-articular knee anatomy in children with achondroplasia who underwent knee arthroscopy. Methods Records of achondroplasia patients who underwent knee arthroscopy between 2009 and 2014 were reviewed. Demographic data, operative reports, follow-up notes, MRI and arthroscopy images were reviewed. Bony, cartilaginous and ligamentous changes were noted. The trochlea sulcus angle was measured from intra-operative arthroscopic images. Results A total of 12 knee arthroscopies in nine patients were performed. The mean age at surgery was 16.9 years (12 to 22). In all patients, the indication for surgery was knee pain and/or mechanical symptoms that were refractory to non-operative treatment. Three anatomical variations involving the distal femur were found in all knees: a deep femoral trochlea; a high A-shaped intercondylar notch; and a vertically oriented anterior cruciate ligament. The average trochlea sulcus angle measured 123°. Pathology included: synovial plica (one knee); chondral lesions (three knees); discoid lateral meniscus (11 knees); and meniscal tears (six knees). All patients were pain-free and returned to normal activity at final follow-up. Conclusion Children with achondroplasia have characteristic distal femur anatomy noted during knee arthroscopy. These variations should be considered normal during knee arthroscopy in these patients. Arthroscopic findings confirmed previous MRI findings within this specific population with the addition of a deep trochlear groove which was not previously reported. PMID:28828058

    Holliday, Casey M

    2009-09-01

    Jaw muscles are key components of the head and critical to testing hypotheses of soft-tissue homology, skull function, and evolution. Dinosaurs evolved an extraordinary diversity of cranial forms adapted to a variety of feeding behaviors. However, disparate evolutionary transformations in head shape and function among dinosaurs and their living relatives, birds and crocodylians, impair straightforward reconstructions of muscles, and other important cephalic soft tissues. This study presents the osteological correlates and inferred soft tissue anatomy of the jaw muscles and relevant neurovasculature in the temporal region of the dinosaur head. Hypotheses of jaw muscle homology were tested across a broad range archosaur and sauropsid taxa to more accurately infer muscle attachments in the adductor chambers of non-avian dinosaurs. Many dinosaurs likely possessed m. levator pterygoideus, a trait shared with lepidosaurs but not extant archosaurs. Several major clades of dinosaurs (e.g., Ornithopoda, Ceratopsidae, Sauropoda) eliminated the epipterygoid, thus impacting interpretations of m. pseudotemporalis profundus. M. pseudotemporalis superficialis most likely attached to the caudoventral surface of the laterosphenoid, a trait shared with extant archosaurs. Although mm. adductor mandibulae externus profundus and medialis likely attached to the caudal half of the dorsotemporal fossa and coronoid process, clear osteological correlates separating the individual bellies are rare. Most dinosaur clades possess osteological correlates indicative of a pterygoideus ventralis muscle that attaches to the lateral surface of the mandible, although the muscle may have extended as far as the jugal in some taxa (e.g., hadrosaurs, tyrannosaurs). The cranial and mandibular attachments of mm adductor mandibulae externus superficialis and adductor mandibulae posterior were consistent across all taxa studied. These new data greatly increase the interpretive resolution of head anatomy in

    Magnetic resonance imaging (MRI) was performed in 36 patients at between 10 and 38 weeks gestation to determine the fetal anatomy that could be identified at different gestations. Fetal motion significantly degraded the image quality in the first and second trimesters, but in the final trimester fetal anatomy was clearly demonstrated. T2 weighted sequences showed the fetal brain and lungs to have a high signal intensity. Shorter TR leading to a T1 weighting gave better resolution of the overall anatomy. MRI has revealed the potential for assessment of lung maturity and the growth-retarded fetus.

    As the field of reconstructive pelvic surgery continues to evolve, with descriptions of new procedures to repair pelvic organ prolapse, it remains imperative to maintain a functional understanding of pelvic floor anatomy and support. The goal of this review was to provide a focused, conceptual approach to differentiating anatomic defects contributing to prolapse in the various compartments of the vagina. Rather than provide exhaustive descriptions of pelvic floor anatomy, basic pelvic floor anatomy is reviewed, new and historical concepts of pelvic floor support are discussed, and relevance to the surgical management of specific anatomic defects is addressed.

    Marked changes are occurring within both the medical and dental curricula and new ways of teaching the basic sciences have been devised and traditional methods (e.g., dissection for gross anatomy and of bench-based animal preparations for physiology) are increasingly no longer the norm. Although there is much anecdotal evidence that students are not in favor of such changes, there is little evidence for this based on quantitative analyses of students' attitudes. Using Thurstone and Chave attitude analyses, we assessed the attitudes of first year medical and dental students at Cardiff University toward gross anatomy and physiology in terms of their perceived clinical importance. In addition, we investigated the appropriateness ("fitness for purpose") of teaching methodologies used for anatomy and physiology. The hypotheses tested recognized the possibility that medical and dental students differed in their opinions, but that they had a preference to being taught gross anatomy through the use of dissection and had no preference for physiology teaching. It was found that both medical and dental students displayed positive attitudes toward the clinical relevance of gross anatomy and that they preferred to be taught by means of dissection. Although both medical and dental students displayed positives attitudes toward the clinical relevance of physiology, this was greater for the medical students. Both medical and dental students showed a preference for being taught physiology through didactic teaching in small groups but the medical students also appreciated being taught by means of practicals. Overall, this study highlights the expectations that students have for the basic science foundation teaching within their professional training and signals a preference for being taught experientially/practically. Differences were discerned between medical and dental students that might reflect the direct association between systems physiology and pathophysiology and the

  5. Coronary Artery Anomalies in Animals.

    Coronary artery anomalies represent a disease spectrum from incidental to life-threatening. Anomalies of coronary artery origin and course are well-recognized in human medicine, but have received limited attention in veterinary medicine. Coronary artery anomalies are best described in the dog, hamster, and cow though reports also exist in the horse and pig. The most well-known anomaly in veterinary medicine is anomalous coronary artery origin with a prepulmonary course in dogs, which limits treatment of pulmonary valve stenosis. A categorization scheme for coronary artery anomalies in animals is suggested, dividing these anomalies into those of major or minor clinical significance. A review of coronary artery development, anatomy, and reported anomalies in domesticated species is provided and four novel canine examples of anomalous coronary artery origin are described: an English bulldog with single left coronary ostium and a retroaortic right coronary artery; an English bulldog with single right coronary ostium and transseptal left coronary artery; an English bulldog with single right coronary ostium and absent left coronary artery with a prepulmonary paraconal interventricular branch and an interarterial circumflex branch; and a mixed-breed dog with tetralogy of Fallot and anomalous origin of all coronary branches from the brachiocephalic trunk. Coronary arterial fistulae are also described including a coronary cameral fistula in a llama cria and an English bulldog with coronary artery aneurysm and anomalous shunting vessels from the right coronary artery to the pulmonary trunk. These examples are provided with the intent to raise awareness and improve understanding of such defects.

    Codd, Anthony M; Choudhury, Bipasha

    2011-01-01

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

    Rhizocephalan parasites are dioecious organisms, in that one or several dwarf males are implanted into the external part of the female parasite soon after it emerges from the interior of the host animal. The structure of the female externa and its resident males is crucial for understanding both...... the reproductive biology and the taxonomy of these specialized parasites. We use scanning electron microscopy and histological methods to study the anatomy of juvenile and the mature externae of the rhizocephalan barnacle Loxothylacus texanus parasitizing the blue crab Callinectes rathbunae. We put emphasis......, as is characteristic for the genus Loxothylacus. The internal anatomy of the mature externa of L. texanus is in most features similar to that seen in other species of the Sacculinidae, which comprises the majority of rhizocephalan species. However, the single receptacle creates a situation where the two implanted...

    Is anatomy a dying discipline? This article explores the history and current state of human anatomy in Australasia, and considers the changing nature of the discipline, and possibilities for the future. A web-based search of all tertiary institutions in Australasia was performed to identify which taught anatomy. Those identified were invited to provide further information about postgraduate student numbers, external courses and public outreach. Forty-one institutions across Australasia teach anatomy. There are seven identifiable anatomy departments and nine disciplines of anatomy. From 1900 to 2014, the number of medical schools has increased (from 4 to 20), however a concomitant increase in the number of anatomy departments (2014, n = 7) was not observed. Twenty-one institutions, without medical schools, currently teach anatomy but none have a stand-alone anatomy department. Anatomy is taught in more than 18 different undergraduate and postgraduate programs. From the 28 institutions that provided current data, 310 postgraduate research students were identified. Predominantly, they came from longer-established institutions with an identifiable anatomy department. Similarly, those with anatomy departments/disciplines offered external professional courses. Many institutions engaged in public outreach. The evidence suggests that anatomy is alive and possibly even growing in Australasia. However, the structures around the discipline and the students who are learning anatomy are changing. Our challenge is to prepare the next generation of anatomy faculty to be both researchers and teachers. © 2015 Wiley Periodicals, Inc.

    To demonstrate the importance of being familiar with the anatomy of the endopelvic fascia as seen by laparoscopy to perform safe laparoscopic hysterectomies. Combination of surgical videos and design diagrams. Compiled high-definition surgical videos from the Galaxy Care Laparoscopy Institute, Pune, India. These videos clearly demonstrate the anatomy of the endopelvic fascia and describe tips to avoid damage to the major structures, including the major vessels, ureter, bowel, bladder, and endopelvic fascia. The laparoscopic view of the anatomy with the current camera system is an excellent tool to demonstrate and teach pelvic anatomy, which can be applied to surgical principles in difficult benign and oncological cases. We used a total laparoscopic approach to demonstrate the fasciae that were seen during various types of hysterectomies. The video shows the following: (1) the posterior leaf of the broad ligament was opened until it reached the apex of the uterosacral ligament; (2) the anterior leaf of broad ligament was opened until it reached the vesico-uterine peritoneal reflection; (3) the principles of bladder dissection; (4) the pubocervico-vesical fascia and its relevance to bladder dissection; (5) the relevance of the anatomy of the uterine artery, vein, and ureter with endopelvic fascia within the leaves of the broad ligament; (6) Denonvillier's fascia dissection technique for dissection of the rectum away from the vagina; (7) the anatomy of the vesicocervical ligaments, forming the ureteric tunnel; (8) the dissection principles of lateralizing the ureter in the retrovesical region; (9) the endopelvic fascia reflection, which continued caudally, covering the pelvic floor; and (10) the relevance of the anatomy of the endopelvic fascia and the stress urinary incontinence treatment technique. Understanding the anatomy of the fasciae of the pelvis helps to create avascular planes and is crucial for performing safe hysterectomies. Copyright © 2015 AAGL

    The aim of the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG) Integrated and Elective Training Program is to ensure trainees have both clinical and surgical competence. The capacity to recognise important anatomical structures underpins this aim; however, quantification of RANZCOG trainees' anatomical knowledge and their training and assessment is not available. To survey trainees at all levels relating to applied anatomy, training and assessment within the RANZCOG training program. All accredited RANZCOG trainees were invited to participate in an online survey relating to anatomy knowledge, application, assessment and means of improving anatomical training. At the commencement of training, 11% of trainees perceived their anatomical knowledge as adequate and this increased to 77% by the final year of training. For final-year trainees, 78% perceived their anatomy knowledge as sufficient to perform a total abdominal hysterectomy and 87% an ovarian cystectomy or salpingectomy. Eighty-four per cent of trainees perceived the RANZCOG training programme as providing inadequate anatomy teaching. 100% of respondents supported a RANZCOG approved anatomy training course. This is a survey-based study and therefore subjective. Consequently, accurate determination of anatomical knowledge for RANZCOG trainees is inexact. Trainees perceive limitations in their anatomical knowledge. A formalised RANZCOG anatomy course would be of value in providing structured education and assessment of trainees' knowledge and establishing whether there are improvements in surgical competencies. © 2014 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Designing a new approach for learning gross anatomy to improve students' motivation to study anatomy and to enable them to learn independently through case discussion. The study included newly registered students in the first academic year. The total number of students was 165, who were divided by alphabetical order into 15 groups of 11 students. Each group was led by one faculty member and each faculty member lead 3 groups. Each group met twice a week for 2 weeks to discuss one case related to the upper limb anatomy. Students took pre- and posttests and completed an opinion questionnaire about the case discussions. The pretest score shows that 20% of the students received grades of 60% or above and that 80% received grades less than 60%. The posttest showed that 45% of the students received grades of 60% or above and that 55% received grades less than 60%. There was a significant difference between the pre- and posttest for grades 60% (P = 0.0023). In addition, 17% of students achieved the same results (less than 60%) in both the pre- and posttests. The questionnaire revealed that all students stated that the discussion method was useful in their learning process, helped them to increase their motivation to study anatomy (85%), know the usefulness of studying anatomy (84%), and understand the problems (91%). The implementation of the case discussion in teaching anatomy can increase the students' understanding and motivate them to learn.

    The study of anatomy remains the backbone of medical education in the first years. There is a constant need for educational materials that enable the assimilation of knowledge by students. The casts after human bodies have not lost the value, even in the era of virtual education. We present in this paper a museal item destined to improve the anatomy teaching. Given the existence in the department of anatomy from Cluj -Napoca of an item of exceptional artistic and scientific value, we intensively searched Pubmed and Scopus, as well as by manual search of printed only documents, for all papers related to the muscle man by Brancusi created for educational purposes of anatomy students. This paper presents summary data from the biography of the creators of this item, the world famous sculptor Constantin Brancusi and the professor of anatomy and surgery from Bucharest Dimitrie Gerota. We also describe this item and the conditions which generated it. Teaching anatomy relies on the quality of the didactic support. The muscle man by Brancusi is a very realistic reproduction of a man, very useful for anatomical training and teaching.

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

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

    2016-01-01

    This article discusses the notion that the invisibility of the animalness of the animal constitutes a fundamental obstacle to change within current production systems. It is discussed whether housing animals in environments that resemble natural habitats could lead to a re-animalization...... of the animals, a higher appreciation of their moral significance, and thereby higher standards of animal welfare. The basic claim is that experiencing the animals in their evolutionary and environmental context would make it harder to objectify animals as mere bioreactors and production systems. It is argued...... that the historic objectification of animals within intensive animal production can only be reversed if animals are given the chance to express themselves as they are and not as we see them through the tunnel visions of economy and quantifiable welfare assessment parameters....

  17. Animal rights, animal minds, and human mindreading.

    Science.gov (United States)

    Mameli, M; Bortolotti, L

    2006-02-01

    Do non-human animals have rights? The answer to this question depends on whether animals have morally relevant mental properties. Mindreading is the human activity of ascribing mental states to other organisms. Current knowledge about the evolution and cognitive structure of mindreading indicates that human ascriptions of mental states to non-human animals are very inaccurate. The accuracy of human mindreading can be improved with the help of scientific studies of animal minds. However, the scientific studies do not by themselves solve the problem of how to map psychological similarities (and differences) between humans and animals onto a distinction between morally relevant and morally irrelevant mental properties. The current limitations of human mindreading-whether scientifically aided or not-have practical consequences for the rational justification of claims about which rights (if any) non-human animals should be accorded.

    To determine which organs can be reliably visualized ultrasonographically in bearded dragons (Pogona vitticeps), describe their normal ultrasonographic appearance, and describe an ultrasonographic technique for use with this species. Cross-sectional study. 14 healthy bearded dragons (6 females and 8 males). Bearded dragons were manually restrained in dorsal and sternal recumbency, and coelomic organs were evaluated by use of linear 7- to 15-MHz and microconvex 5- to 8-MHz transducers. Visibility, size, echogenicity, and ultrasound transducer position were assessed for each organ. Coelomic ultrasonography with both microconvex and linear ultrasound transducers allowed for visualization of the heart, pleural surface of the lungs, liver, caudal vena cava, aorta, ventral abdominal vein, gallbladder, fat bodies, gastric fundus, cecum, colon, cloaca, kidneys, and testes or ovaries in all animals. The pylorus was visualized in 12 of 14 animals. The small intestinal loops were visualized in 12 of 14 animals with the linear transducer, but could not be reliably identified with the microconvex transducer. The hemipenes were visualized in 7 of 8 males. The adrenal glands and spleen were not identified in any animal. Anechoic free coelomic fluid was present in 11 of 14 animals. Heart width, heart length, ventricular wall thickness, gastric fundus wall thickness, and height of the caudal poles of the kidneys were positively associated with body weight. Testis width was negatively associated with body weight in males. Results indicated coelomic ultrasonography is a potentially valuable imaging modality for assessment of most organs in bearded dragons and can be performed in unsedated animals.

  19. [Well-being--intrinsic value--integrity. Developments in the reevaluation of the domesticated animal].

    Science.gov (United States)

    Grommers, F J; Rutgers, L J; Wijsmuller, J M

    1995-09-01

    Owing to selective breeding and conditioning to husbandry methods, domestication has resulted in modification of the anatomy, physiology, and behaviour of animals. Nevertheless, domestic animals cannot be regarded and treated as artificial products. Public interest and concern about the welfare of domestic animals has led to the recognition of the intrinsic value of animals and, in extension of this, to the ethical principle of respect for the integrity of animals. The sensibility and acceptance of these principles by those involved in ethical decision-making depends on their fundamental views about humans and the living world. In order to make judgements about the use of, and interference with, animals, it is desirable to clarify these personal views. The principle of respect for the integrity of animals leads to considerations and arguments beyond animal health and welfare. This is shown by three examples: declawing of cats, caesarean section in cattle, and laying hens in battery cages.

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

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

    2018-03-01

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

    Educational institutions are under tremendous pressure to adopt the newest technologies in order to prepare their students to meet the challenges of the twenty-first century. For the last twenty years huge amounts of money have been spent on computers, printers, software, multimedia projection equipment, and so forth. A reasonable question is, "Has it worked?" Has this infusion of resources, financial as well as human, resulted in improved learning? Are the students meeting the intended learning goals? Any attempt to develop answers to these questions should include examining the intended goals and exploring the effects of the changes on students and faculty. This project investigated the impact of a specific application of a computer program in a community college setting on students' attitudes and understanding of human anatomy and physiology. In this investigation two sites of the same community college with seemingly similar students populations, seven miles apart, used different laboratory activities to teach human anatomy and physiology. At one site nursing students were taught using traditional dissections and laboratory activities; at the other site two of the dissections, specifically cat and sheep pluck, were replaced with the A.D.A.M.RTM (Animated Dissection of Anatomy for Medicine) computer program. Analysis of the attitude data indicated that students at both sites were extremely positive about their laboratory experiences. Analysis of the content data indicated a statistically significant difference in performance between the two sites in two of the eight content areas that were studied. For both topics the students using the computer program scored higher. A detailed analysis of the surveys, interviews with faculty and students, examination of laboratory materials, and observations of laboratory facilities in both sites, and cost-benefit analysis led to the development of seven recommendations. The recommendations call for action at the level of the

    During the last 20 years pigs have become increasingly popular in large animal translational neuroscience research as an economical and ethical feasible substitute to non-human primates. The anatomy of the pig telencephalon is, however, not well known. We present, accordingly, a detailed description of the surface anatomy and cytoarchitecture of the Göttingen minipig telencephalon based on macrophotos and consecutive high-power microphotographs of 15 μm thick paraffin embedded Nissl-stained coronal sections. In 1-year-old specimens the formalin perfused brain measures approximately 55 × 47 × 36 mm (length, width, height) and weighs around 69 g. The telencephalic part of the Göttingen minipig cerebrum covers a large surface area, which can be divided into a neocortical gyrencephalic part located dorsal to the rhinal fissure, and a ventral subrhinal part dominated by olfactory, amygdaloid, septal, and hippocampal structures. This part of the telencephalon is named the subrhinal lobe, and based on cytoarchitectural and sulcal anatomy, can be discerned from the remaining dorsally located neocortical perirhinal/insular, pericallosal, frontal, parietal, temporal, and occipital lobes. The inner subcortical structure of the minipig telencephalon is dominated by a prominent ventricular system and large basal ganglia, wherein the putamen and the caudate nucleus posterior and dorsally are separated into two entities by the internal capsule, whereas both structures ventrally fuse into a large accumbens nucleus. The presented anatomical data is accompanied by surface renderings and high-power macrophotographs illustrating the telencephalic sulcal pattern, and the localization of the identified lobes and cytoarchitectonic areas. Additionally, 24 representative Nissl-stained telencephalic coronal sections are presented as supplementary material in atlas form on http://www.cense.dk/minipig_atlas/index.html and referred to as S1-S24 throughout the manuscript.

    The ring-tailed lemur (Lemur catta) is primarily distributed in south and southwestern Madagascar. It is classified as an endangered species by the International Union for Conservation of Nature. Various abdominal diseases, such as hepatic lipidosis, intestinal ulcers, cystitis, urinary tract obstruction, and neoplasia (e.g., colonic adenocarcinoma and cholangiocarcinoma), have been reported in this species. The aim of this study was to describe the normal radiographic and ultrasonographic abdominal anatomy in captive ring-tailed lemurs to provide guidance for clinical use. Radiography of the abdomen and ultrasonography of the liver, spleen, kidneys, and urinary bladder were performed in 13 and 9 healthy captive ring-tailed lemurs, respectively, during their annual health examinations. Normal radiographic and ultrasonographic reference ranges for abdominal organs were established and ratios were calculated. The majority (12/13) of animals had seven lumbar vertebrae. The sacrum had mainly (12/13) three segments. Abdominal serosal detail was excellent in all animals, and hypaxial muscles were conspicuous in the majority (11/13) of animals. The spleen was frequently (12/13) seen on the ventrodorsal (VD) view and rarely (3/13) on the right lateral (RL) view. The liver was less prominent and well contained within the ribcage. The pylorus was mostly (11/13) located to the right of the midline. The right and left kidneys were visible on the RL and VD views, with the right kidney positioned more cranial and dorsal to the left kidney. On ultrasonography, the kidneys appeared ovoid on transverse and longitudinal views. The medulla was hypoechoic to the renal cortex. The renal cortex was frequently (8/9) isoechoic and rarely (1/9) hyperechoic to the splenic parenchyma. The liver parenchyma was hypoechoic (5/5) to the renal cortex. Knowledge of the normal radiographic and ultrasonographic abdominal anatomy of ring-tailed lemurs may be useful in the diagnosis of diseases and in

  10. Functional anatomy and biomechanics of the carpus

    The wrist is an exceedingly complex structure composed of several joints and a dedicated ligamentous system. Its functional principles allow a wide range of carpal motion and make the wrist remarkably resistant to external stress forces: The proximal carpal row serves as an intercalated link interposed between the static elements of both the forearm and the distal carpal row. Like a flexible placeholder, the proximal row synchronously adapts to the spatial and temporal requirements of the wrist. There are synergistic movement patterns including simultaneous flexion of the proximal row as the wrist is deviated radially and simultaneous extension during ulnar deviation. Together with pronosupination of the radioulnar joints, the combined radial/ulnar inclination and flexion/extension enable spherical, out-of-plane movements of the hand. Carpal function is best explained by the ''model of a ring under tension.'' This review addresses the anatomy and the biomechanics of the wrist and illustrates systematic image analysis by using carpal lines and angles as well as indices of carpal height. (orig.) [de

    The elbow and wrist anatomy of 17 felid species were studied and compared with that of other representative mammaliam carnivores. Based on the shape and position of the olecranon fossa, it was determined that for felids the forelimb cannot travel in a "pendulum-like" motion during locomotion, but must travel through an arch away from the parasagittal plane of the body. For the anterior limb, the degree of deviation from the parasagittal plane was correlated with habitat preference. In this regard, those felids that are exclusive forest dwellers (found exclusively in high, densely structured habitats) had the greatest angle of inclination of the olecranon fossa. In addition, these, species had a large lateral olecranon tuberosity for the attachment of the lateral head of the triceps muscle. For those felids that inhabit more open terrain (low-structured habitat), the olecranon fossa was less inclined, the medical olecranon tuberosity relatively large, and the medial head of the triceps was significantly heavier than those of the forest felids. Both the wrist and elbow joints exhibited a large degree of mobility which was reflective of the claw-equipped forelimb being used as a hunting weapon.

    The deep lymphatic anatomy of the hand still remains the least described in medical literature. Eight hands were harvested from four nonembalmed human cadavers amputated above the wrist. A small amount of 6% hydrogen peroxide was employed to detect the lymphatic vessels around the superficial and deep palmar vascular arches, in webs from the index to little fingers, the thenar and hypothenar areas. A 30-gauge needle was inserted into the vessels and injected with a barium sulphate compound. Each specimen was dissected, photographed and radiographed to demonstrate deep lymphatic distribution of the hand. Five groups of deep collecting lymph vessels were found in the hand: superficial palmar arch lymph vessel (SPALV); deep palmar arch lymph vessel (DPALV); thenar lymph vessel (TLV); hypothenar lymph vessel (HTLV); deep finger web lymph vessel (DFWLV). Each group of vessels drained in different directions first, then all turned and ran towards the wrist in different layers. The deep lymphatic drainage of the hand has been presented. The results will provide an anatomical basis for clinical management, educational reference and scientific research. Copyright © 2018 Elsevier GmbH. All rights reserved.

  13. Neuroembryology and functional anatomy of craniofacial clefts

    Directory of Open Access Journals (Sweden)

    Ewings Ember

    2009-10-01

    Full Text Available The master plan of all vertebrate embryos is based on neuroanatomy. The embryo can be anatomically divided into discrete units called neuromeres so that each carries unique genetic traits. Embryonic neural crest cells arising from each neuromere induce development of nerves and concomitant arteries and support the development of specific craniofacial tissues or developmental fields. Fields are assembled upon each other in a programmed spatiotemporal order. Abnormalities in one field can affect the shape and position of developing adjacent fields. Craniofacial clefts represent states of excess or deficiency within and between specific developmental fields. The neuromeric organization of the embryo is the common denominator for understanding normal anatomy and pathology of the head and neck. Tessier′s observational cleft classification system can be redefined using neuroanatomic embryology. Reassessment of Tessier′s empiric observations demonstrates a more rational rearrangement of cleft zones, particularly near the midline. Neuromeric theory is also a means to understand and define other common craniofacial problems. Cleft palate, encephaloceles, craniosynostosis and cranial base defects may be analyzed in the same way.

  15. Functional anatomy and physiology of gastric secretion.

    Schubert, Mitchell L

    2015-11-01

    This review summarizes the past year's literature regarding the neuroendocrine and intracellular regulation of gastric acid secretion, discussing both basic and clinical aspects. Gastric acid facilitates the digestion of protein as well as the absorption of iron, calcium, vitamin B12, and certain medications. High acidity kills ingested microorganisms and limits bacterial overgrowth, enteric infection, and possibly spontaneous bacterial peritonitis. The main stimulants of acid secretion are gastrin, released from antral gastrin cells; histamine, released from oxyntic enterochromaffin-like cells; and acetylcholine, released from antral and oxyntic intramural neurons. Ghrelin and coffee also stimulate acid secretion whereas somatostatin, cholecystokinin, glucagon-like peptide-1, and atrial natriuretic peptide inhibit acid secretion. Although 95% of parietal cells are contained within the oxyntic mucosa (fundus and body), 50% of human antral glands contain parietal cells. Proton pump inhibitors are considered well tolerated drugs, but concerns have been raised regarding dysbiosis, atrophic gastritis, hypergastrinemia, hypomagnesemia, and enteritis/colitis. Our understanding of the functional anatomy and physiology of gastric secretion continues to advance. Such knowledge is crucial for improved management of acid-peptic disorders, prevention and management of neoplasia, and the development of novel medications.

    Massive amounts of fake news and conspiratorial content have spread over social media before and after the 2016 US Presidential Elections despite intense fact-checking efforts. How do the spread of misinformation and fact-checking compete? What are the structural and dynamic characteristics of the core of the misinformation diffusion network, and who are its main purveyors? How to reduce the overall amount of misinformation? To explore these questions we built Hoaxy, an open platform that enables large-scale, systematic studies of how misinformation and fact-checking spread and compete on Twitter. Hoaxy captures public tweets that include links to articles from low-credibility and fact-checking sources. We perform k-core decomposition on a diffusion network obtained from two million retweets produced by several hundred thousand accounts over the six months before the election. As we move from the periphery to the core of the network, fact-checking nearly disappears, while social bots proliferate. The number of users in the main core reaches equilibrium around the time of the election, with limited churn and increasingly dense connections. We conclude by quantifying how effectively the network can be disrupted by penalizing the most central nodes. These findings provide a first look at the anatomy of a massive online misinformation diffusion network.

    Full Text Available Bell's Palsy is a peripheral facial nerve weakness (facial nerve with acute onset on one side of the face. This condition causes the inability of the patient to move half of his face consciously (volunter on the affected side. The Bell's Palsy incidence is 20-30 cases out of 100.000 people and accounts for 60-70% of all cases of unilateral facial paralysis. The disease is self-limited, but causes great suffering for patients who are not treated properly. Controversy in the management is still debated, and the cause is still unknown. The underlying hypothesis is ischemic, vascular, viral, bacterial, hereditary, and immunologic. Therapy done so far is to improve facial nerve function and healing process. The management of the therapy used will be closely related to the structure of the anatomy and its functions and associated abnormalities. The modalities of Bell's Palsy therapy are with corticosteroids and antivirals, facial exercises, electrostimulation, physiotherapy and decompression operations. Approximately 80-90% of patients with Bell's palsy recover completely within 6 months, even in 50-60% of cases improved within 3 weeks. Approximately 10% experienced persistent facial muscle asymmetry, and 5% experienced severe sequelae, and 8% of cases were recurrent.

    Flexor tendon pulley has been very early noticed and described. Terminology usually accepted recognizes 6 arcifom pulleys (A0 to A5) and 3 cruciform pulleys (C1 to C3). Anatomy and physiology of this flexor tendon gliding and reflection system at the level of the digital sheet are exposed. The integrity necessity of this system became obvious regarding the flexor tendons repair. Four main pathologies may be concerned: the trigger finger congenital or progressive, due to a chondroid metaplasia of the A1 pulley; tenosynovial ganglions arising at the weak point between A1 and A2 pulley; lesions of the flexor tendon sheet during traumatic lacerations or surgical repairs; quite experimental lesions creating isolated ruptures of one or several pulleys which occur during sport practice, especially high level rock climbing. The repair techniques are exposed to allow to graduate and hierarchy the reparation technique regarding the pathology. A2 and A4 repair is always indicated. The best reconstruction material is an extensor retinaculum graft. But its poor surface available often draws to use conventional palmaris longus free graft.

    1982-01-01

    To analyse the anatomo-radiological correlation of the spine and spinal cord, 22 formalized, frozen anatomical specimens corresponding to different regions of the spinal column (8 cervical, 5 dorsal, and 9 lumbar) were studied by CT scans on axial, sagittal and coronal planes and by contact radiography after they were cut into anatomical slices in order to clarify the normal CT anatomy of the spinal column. The results obtained from CT patient scans, performed exclusively on the axial plane, were compared with those obtained from the anatomical specimens (both CT and contrast radiography). High resolution CT programs were used, enabling us to obtain better individualization of the normal structures contained in the spinal column. Direct sagittal and coronal sections were performed on the specimens in order to get further anatomo-radiological information. Enhanced CT studies of the specimens were also available because of the air already present in the subarachnoid spaces. Excellent visualization was obtained of bone structures, soft tissue and the spinal cord. High CT resolution of the spine appeares to be an excellent neuroradiological procedure to study the spine and spinal cord. A metrizamide CT scan is, however, necessary when a normal unenhanced CT scan is insufficient for diagnosis and when the spinal cord is not clearly visible, as often happens at the cervical level. Clinical findings are certainly very useful to ascertain the exact CT level and to limit the radiation exposure. (orig.)

    Wedel, T; Böttner, M

    2014-04-01

    Although diverticular disease is one of the most frequent gastrointestinal disorders the pathogenesis is not yet sufficiently clarified. The aim is to define the anatomy and pathogenesis of diverticular disease considering the risk factors and description of structural and functional alterations of the bowel wall. This article gives an appraisal of the literature, presentation and evaluation of classical etiological factors, analysis and discussion of novel pathogenetic concepts. Colonic diverticulosis is defined as an acquired out-pouching of multiple and initially asymptomatic pseudodiverticula through muscular gaps in the colon wall. Diverticular disease is characterized by diverticular bleeding and/or inflammatory processes (diverticulitis) with corresponding complications (e.g. abscess formation, fistula, covered and open perforation, peritonitis and stenosis). Risk factors for diverticular disease include increasing age, genetic predisposition, congenital connective tissue diseases, low fiber diet, high meat consumption and pronounced overweight. Alterations of connective tissue cause a weakening of preformed exit sites of diverticula and rigidity of the bowel wall with reduced flexibility. It is assumed that intestinal innervation disorders and structural alterations of the musculature induce abnormal contractile patterns with increased intraluminal pressure, thereby promoting the development of diverticula. Moreover, an increased release of pain-mediating neurotransmitters is considered to be responsible for persistent pain in chronic diverticular disease. According to the present data the pathogenesis of diverticular disease cannot be attributed to a single factor but should be considered as a multifactorial event.

    Full Text Available ABSTRACT Anthracological studies are firmly advancing in the tropics during the last decades. The theoretical and methodological bases of the discipline are well established. Yet, there is a strong demand for comparative reference material, seeking for an improvement in the precision of taxonomic determination, both in palaeoecological and palaeoethnobotanical studies and to help preventing illegal charcoal production. This work presents descriptions of charcoal anatomy of eleven Anacardiaceae species from six genera native to Brazil (Anacardium occidentale, Anacardium parvifolium, Astronium graveolens, Astronium lecointei, Lithrea molleoides, Schinus terebenthifolius, Spondias mombin, Spondias purpurea, Spondias tuberosa, Tapirira guianensis, and Tapirira obtusa. They are characterized by diffuse-porous wood, vessels solitary and in multiples, tyloses and spiral thickenings sometimes present; simple perforation plates, alternate intervessel pits, rounded vessel-ray pits with much reduced borders to apparently simple; parenchyma paratracheal scanty to vasicentric; heterocellular rays, some with radial canals and crystals; septate fibres with simple pits. These results are quite similar to previous wood anatomical descriptions of the same species or genera. Yet, charcoal identification is more effective when unknown samples are compared to charred extant equivalents, instead of to wood slides.

    The role of the cardiac lymphatic system has been recently appreciated since lymphatic disturbances take part in various heart pathologies. This review presents the current knowledge about normal anatomy and structure of lymphatics and their prenatal development for a better understanding of the proper functioning of this system in relation to coronary circulation. Lymphatics of the heart consist of terminal capillaries of various diameters, capillary plexuses that drain continuously subendocardial, myocardial, and subepicardial areas, and draining (collecting) vessels that lead the lymph out of the heart. There are interspecies differences in the distribution of lymphatic capillaries, especially near the valves, as well as differences in the routes and number of draining vessels. In some species, subendocardial areas contain fewer lymphatic capillaries as compared to subepicardial parts of the heart. In all species there is at least one collector vessel draining lymph from the subepicardial plexuses and running along the anterior interventricular septum under the left auricle and further along the pulmonary trunk outside the heart and terminating in the right venous angle. The second collector assumes a different route in various species. In most mammalian species the collectors run along major branches of coronary arteries, have valves and a discontinuous layer of smooth muscle cells. PMID:24592145

    The two main sources of blood supply to the lungs and their supporting structures are the pulmonary and bronchial arteries. The bronchial arteries account for 1% of the cardiac output but can be recruited to provide additional systemic circulation to the lungs in various acquired and congenital thoracic disorders. An understanding of bronchial artery anatomy and function is important in the identification of bronchial artery dilatation and anomalies and the formulation of an appropriate differential diagnosis. Visualization of dilated bronchial arteries at imaging should alert the radiologist to obstructive disorders that affect the pulmonary circulation and prompt the exclusion of diseases that produce or are associated with pulmonary artery obstruction, including chronic infectious and/or inflammatory processes, chronic thromboembolic disease, and congenital anomalies of the thorax (eg, proximal interruption of the pulmonary artery). Conotruncal abnormalities, such as pulmonary atresia with ventricular septal defect, are associated with systemic pulmonary supply provided by aortic branches known as major aortopulmonary collaterals, which originate in the region of the bronchial arteries. Bronchial artery malformation is a rare left-to-right or left-to-left shunt characterized by an anomalous connection between a bronchial artery and a pulmonary artery or a pulmonary vein, respectively. Bronchial artery interventions can be used successfully in the treatment of hemoptysis, with a low risk of adverse events. Multidetector computed tomography helps provide a vascular road map for the interventional radiologist before bronchial artery embolization. RSNA, 2015

    Marine animals contain various carotenoids that show structural diversity. These marine animals accumulate carotenoids from foods such as algae and other animals and modify them through metabolic reactions. Many of the carotenoids present in marine animals are metabolites of β-carotene, fucoxanthin, peridinin, diatoxanthin, alloxanthin, and astaxanthin, etc. Carotenoids found in these animals provide the food chain as well as metabolic pathways. In the present review, I will describe marine animal carotenoids from natural product chemistry, metabolism, food chain, and chemosystematic viewpoints, and also describe new structural carotenoids isolated from marine animals over the last decade.

    In a problem-based learning curriculum, most medical students research the Internet for information for their "learning issues." Internet sites such as "YouTube" have become a useful resource for information. This study aimed at assessing YouTube videos covering surface anatomy. A search of YouTube was conducted from November 8 to 30, 2010 using research terms "surface anatomy," "anatomy body painting," "living anatomy," "bone landmarks," and "dermatomes" for surface anatomy-related videos. Only relevant video clips in the English language were identified and related URL recorded. For each videotape the following information were collected: title, authors, duration, number of viewers, posted comments, and total number of days on YouTube. The data were statistically analyzed and videos were grouped into educationally useful and non-useful videos on the basis of major and minor criteria covering technical, content, authority, and pedagogy parameters. A total of 235 YouTube videos were screened and 57 were found to have relevant information to surface anatomy. Analysis revealed that 15 (27%) of the videos provided useful information on surface anatomy. These videos scored (mean ± SD, 14.0 ± 0.7) and mainly covered surface anatomy of the shoulder, knee, muscles of the back, leg, and ankle, carotid artery, dermatomes, and anatomical positions. The other 42 (73%) videos were not useful educationally, scoring (mean ± SD, 7.4 ± 1.8). The total viewers of all videos were 1,058,634. Useful videos were viewed by 497,925 (47% of total viewers). The total viewership per day was 750 for useful videos and 652 for non-useful videos. No video clips covering surface anatomy of the head and neck, blood vessels and nerves of upper and lower limbs, chest and abdominal organs/structures were found. Currently, YouTube is an inadequate source of information for learning surface anatomy. More work is needed from medical schools and educators to add useful videos on You

  12. Animal Images and Metaphors in Animal Farm

    Directory of Open Access Journals (Sweden)

    Ping Sun

    2015-05-01

    Full Text Available In literary works animal images are frequently used as the “source domain” of a metaphor to disclose the natures of the “target domain”, human beings. This is called “cross-domain mapping” or “conceptual metaphor” in cognitive linguistics, which is based on the similar qualities between animals and human beings. Thus the apparent descriptions of the animals are really the deep revelations of the human beings. Animal Farm is one exemplary product of this special expressing way. Diversified animal images are intelligently used by George Orwell to represent the people, so all the characters are animals in appearance, but humans in nature. Starting from the animal images and then the conceptual metaphors, readers can perceive a fresh understanding of this classical book. In this novel, three conceptual metaphors are identified and the special findings can be illustrated as the following: Firstly, the whole story of the animals represents the history and politics of the Soviet Union. Secondly, the pigs symbolize the authorities of the society. Thirdly, the names of the characters in the novel reveal their identities.

    Morphogenesis of most thoracic organs and structures is not finished with birth but perpetuates in postnatal life. The postnatal growth is partly associated with enormous changes in structure, morphology, and function. Our study presents an overview of morphological, topological and functional peculiarities of thoracic anatomy during infancy, childhood and adolescence. It focuses on the development of the mammary gland, osseous structures of the chest wall, thymus, heart, and lungs. Most of the presented data are based on post-mortem studies. Measurements and numerical data are mainly included for illustration of growth-associated changes. (orig.)

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

  15. Raymond de Vieussens and his contribution to the study of white matter anatomy: historical vignette.

    2012-12-01

    In recent years, there has been a renewed interest in the study of white matter anatomy, both with the use of postmortem dissections and diffusion tensor imaging tractography. One of the precursors in the study of white matter anatomy was Raymond de Vieussens (1641-1716), a French anatomist born in Le Vigan. He studied medicine at the University of Montpellier in southern France, one of the most ancient and lively schools of medicine in Europe. In 1684 Vieussens published his masterpiece, the Neurographia Universalis, which is still considered one of the most complete and accurate descriptions of the nervous system provided in the 17th century. He described the white matter of the centrum ovale and was the first to demonstrate the continuity of the white matter fibers from the centrum ovale to the brainstem. He also described the dentate nuclei, the pyramids, and the olivary nuclei. According to the theory of Galen, Vieussens considered that the function of the white matter was to convey the "animal spirit" from the centrum ovale to the spinal cord. Although neglected, Vieussens' contribution to the study of white matter is relevant. His pioneering work showed that the white matter is not a homogeneous substance, but rather a complex structure rich in fibers that are interconnected with different parts of the brain. These initial results paved the way to advancements observed in later centuries that eventually led to modern hodology.

    The objective of this study was to investigate the anatomy, both macroscopic and microscopic, of the soft tissue internal structures of the hip joint in animal species and in three human hips (an adult and two fetuses). We dissected the hip joints of 16 species and compared the anatomical features of the soft tissue from the respective acetabula. In addition, a histological study was made of the specimens studied. In amphibians, we found a meniscus in the acetabulum, which was not observed in any of the other species studied. The isolated round ligament is observed from birds onwards. In the group of mammals analysed, including the human specimens, we found a meniscoid structure in the acetabular hip joint. Furthermore, we found that the meniscoid structure forms an anatomo-functional unit with the round ligament and the transverse ligament of the coxofemoral joint. These discoveries suggest the participation of the soft tissue anatomy in adaptative changes of species. © 2011 Blackwell Verlag GmbH.

  17. The beauty of anatomy: visual displays and surgical education in early-nineteenth-century London.

    2011-01-01

    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.

In such way, virtual reconstructions of the probable ante-mortem postures of victims can be constructed and contribute to understand the sequence of events. This procedure is demonstrated in two victims of gunshot injuries. Case #1...... was a man showing three perforating gunshot wounds, who died due to the injuries of the incident. Whole-body PMCT was performed and 3D reconstructions of bones, relevant internal organs and bullet paths were generated. Using 3ds Max software and a human anatomy 3D model, a virtual animated body was built...... the anatomical proportions of the patient was made combining the actual bones of the victim with those obtained from the human anatomy 3D model. The resulted 3D model was used for the animation process. Several probable postures were also visualized in this case. It has be shown that in Case #1 the lesions...

  19. Best teaching practices in anatomy education: A critical review.

    Science.gov (United States)

    Estai, Mohamed; Bunt, Stuart

    2016-11-01

    In this report we review the range of teaching resources and strategies used in anatomy education with the aim of coming up with suggestions about the best teaching practices in this area. There is much debate about suitable methods of delivering anatomical knowledge. Competent clinicians, particularly surgeons, need a deep understanding of anatomy for safe clinical procedures. However, because students have had very limited exposure to anatomy during clinical training, there is a concern that medical students are ill-prepared in anatomy when entering clerkships and residency programs. Therefore, developing effective modalities for teaching anatomy is essential to safe medical practice. Cadaver-based instruction has survived as the main instructional tool for hundreds of years, however, there are differing views on whether full cadaver dissection is still appropriate for a modern undergraduate training. The limitations on curricular time, trained anatomy faculty and resources for gross anatomy courses in integrated or/and system-based curricula, have led many medical schools to abandon costly and time-consuming dissection-based instruction in favour of alternative methods of instruction including prosection, medical imaging, living anatomy and multimedia resources. To date, no single teaching tool has been found to meet curriculum requirements. The best way to teach modern anatomy is by combining multiple pedagogical resources to complement one another, students appear to learn more effectively when multimodal and system-based approaches are integrated. Our review suggests that certain professions would have more benefit from certain educational methods or strategies than others. Full body dissection would be best reserved for medical students, especially those with surgical career intentions, while teaching based on prosections and plastination is more suitable for dental, pharmacy and allied health science students. There is a need to direct future research

  20. The functional anatomy of suggested limb paralysis.

    Suggestions of limb paralysis in highly hypnotically suggestible subjects have been employed to successfully model conversion disorders, revealing similar patterns of brain activation associated with attempted movement of the affected limb. However, previous studies differ with regard to the executive regions involved during involuntary inhibition of the affected limb. This difference may have arisen as previous studies did not control for differences in hypnosis depth between conditions and/or include subjective measures to explore the experience of suggested paralysis. In the current study we employed functional magnetic resonance imaging (fMRI) to examine the functional anatomy of left and right upper limb movements in eight healthy subjects selected for high hypnotic suggestibility during (i) hypnosis (NORMAL) and (ii) attempted movement following additional left upper limb paralysis suggestions (PARALYSIS). Contrast of left upper limb motor function during NORMAL relative to PARALYSIS conditions revealed greater activation of contralateral M1/S1 and ipsilateral cerebellum, consistent with the engagement of these regions in the completion of movements. By contrast, two significant observations were noted in PARALYSIS relative to NORMAL conditions. In conjunction with reports of attempts to move the paralysed limb, greater supplementary motor area (SMA) activation was observed, a finding consistent with the role of SMA in motor intention and planning. The anterior cingulate cortex (ACC, BA 24) was also significantly more active in PARALYSIS relative to NORMAL conditions - suggesting that ACC (BA 24) may be implicated in involuntary, as well as voluntary inhibition of prepotent motor responses.

  1. The surgical anatomy of the nasolabial fold.

    The purpose of this cadaver dissection study was to investigate the anatomy of the nasolabial fold with a view to explaining the problems of surgical softening or elimination of the fold. Ten formalin-fixed cadavers and 6 fresh-frozen cadavers were used for this study. In 12 cadavers (8 formalin-fixed, 4 fresh-frozen), the nasolabial fold was sectioned at right angles to the fold for histologic examination, and in 4 cadavers (2 formalin-fixed, 2 fresh-frozen) the epithelium was dissected off the fold to allow for more detailed gross examination of the underlying musculature. The fold was clearly identified on 14 of the cadavers but was indistinct on 2 on gross examination. Beneath the fold were 2 muscle bundles. The more superficial muscle runs parallel to the fold whereas a deeper muscle runs at right angles to it. The buccal fat pad lies above the fold and appears to be retained by horizontal septae in the fat pad and also by the musculature of the fold. Cadavers showing a poorly defined nasolabial fold had fewer muscle bundles to support the fat and fewer fibrous septae running through the fat. The nasolabial fold is defined by structures that support the buccal fat pad and hold it above the fold. This appears to be a combination of muscle bundles that run both across and parallel to the fold and also by fibrous septae supporting the fat pad. This has implications for the development of surgical procedures to soften or eliminate the fold, which must separate the muscles from the dermis of the fold and allow the fat to descend and soften the fold.

  2. Muscular anatomy of the Podocoryna carnea hydrorhiza.

    The muscular anatomy of the athecate hydroid Podocoryna carnea hydrorhiza is elucidated. The polyp-stolon junction is characterized by an opening, here called the chloe, in the otherwise continuous hydrorhizal perisarc. The chloe is elliptical when the polyp first arises, but takes on a more complex outline as multiple stolons anastomose to communicate with that polyp. Surrounding the polyp base are spots, here called anchors, which autofluoresce at the same wavelengths as perisarc and which, like perisarc, contain chitin as assessed by Calcofluor White, Congo Red and wheat germ agglutinin staining. Anchors remain after living tissues are digested using KOH. Collagen IV staining indicates that the mesoglea is pegged to the anchors and rhodamine phallodin staining detects cytoskeletal F-actin fibers of the basal epidermis surrounding the anchors. Longitudinal muscle fibers of the polyp broaden at the polyp base and are inserted into the mesoglea of the underlying stolon, but were neither observed to extend along the stolonal axis nor to attach to the anchors. Circular muscular fibers of the polyp extend into stolons as a dense collection of strands running along the proximal-distal axis of the stolon. These gastrodermal axial muscular fibers extend to the stolon tip. Epidermal cells at the stolon tip and the polyp bud display a regular apical latticework of F-actin staining. A similar meshwork of F-actin staining was found in the extreme basal epidermis of all stolons. Immunohistochemical staining for tubulin revealed nerves at stolon tips, but at no other hydrorhizal locations. These studies bear on the mechanisms by which the stolon tip and polyp bud pulsate, the manner in which the stolon lumen closes, and on the developmental origin of the basal epidermis of the hydrorhiza.

    The central lobe consists of the pre- and postcentral gyri on the lateral surface and the paracentral lobule on the medial surface and corresponds to the sensorimotor cortex. The objective of the present study was to define the neural features, craniometric relationships, arterial supply, and venous drainage of the central lobe. Cadaveric hemispheres dissected using microsurgical techniques provided the material for this study. The coronal suture is closer to the precentral gyrus and central sulcus at its lower rather than at its upper end, but they are closest at a point near where the superior temporal line crosses the coronal suture. The arterial supply of the lower two-thirds of the lateral surface of the central lobe was from the central, precentral, and anterior parietal branches that arose predominantly from the superior trunk of the middle cerebral artery. The medial surface and the superior third of the lateral surface were supplied by the posterior interior frontal, paracentral, and superior parietal branches of the pericallosal and callosomarginal arteries. The venous drainage of the superior two-thirds of the lateral surface and the central lobe on the medial surface was predominantly through the superior sagittal sinus, and the inferior third of the lateral surface was predominantly through the superficial sylvian veins to the sphenoparietal sinus or the vein of Labbé to the transverse sinus. The pre- and postcentral gyri and paracentral lobule have a morphological and functional anatomy that differentiates them from the remainder of their respective lobes and are considered by many as a single lobe. An understanding of the anatomical relationships of the central lobe can be useful in preoperative planning and in establishing reliable intraoperative landmarks.

    Purpose: To investigate the potential advantages of multiple anatomy optimization (MAO) for lung cancer radiation therapy compared to the internal target volume (ITV) approach. Methods: MAO aims to optimize a single fluence to be delivered under free-breathing conditions such that the accumulated dose meets the plan objectives, where accumulated dose is defined as the sum of deformably mapped doses computed on each phase of a single four dimensional computed tomography (4DCT) dataset. Phantom and patient simulation studies were carried out to investigate potential advantages of MAO compared to ITV planning. Through simulated delivery of the ITV- and MAO-plans, target dose variations were also investigated. Results: By optimizing the accumulated dose, MAO shows the potential to ensure dose to the moving target meets plan objectives while simultaneously reducing dose to organs at risk (OARs) compared with ITV planning. While consistently superior to the ITV approach, MAO resulted in equivalent OAR dosimetry at planning objective dose levels to within 2% volume in 14/30 plans and to within 3% volume in 19/30 plans for each lung V20, esophagus V25, and heart V30. Despite large variations in per-fraction respiratory phase weights in simulated deliveries at high dose rates (e.g., treating 4/10 phases during single fraction beams) the cumulative clinical target volume (CTV) dose after 30 fractions and per-fraction dose were constant independent of planning technique. In one case considered, however, per-phase CTV dose varied from 74% to 117% of prescription implying the level of ITV-dose heterogeneity may not be appropriate with conventional, free-breathing delivery. Conclusions: MAO incorporates 4DCT information in an optimized dose distribution and can achieve a superior plan in terms of accumulated dose to the moving target and OAR sparing compared to ITV-plans. An appropriate level of dose heterogeneity in MAO plans must be further investigated.

    Gross anatomy is time consuming to teach and to learn. Because the process of dissection takes up so much student time, assistance in the form of an in-lab instructional DVD program might improve student performance. The DVD could be viewed with a portable device by individual dissection groups at their tables. Groups could dissect at their own pace, with access to step-by-step demonstrations and answers to frequently asked anatomical questions. We created an instructional DVD program demonstrating dissection of the canine ventral neck and thoracic limb. The effect on student exam scores of using the DVD versus not using it was measured in a controlled, two-sample study using incoming first-year veterinary students as volunteers. Volunteers were told the study was of two different dissection methods; the DVD was not specifically mentioned until after the students were separated into two groups (Blue/DVD group and Orange/No DVD group), and then only to volunteers in the Blue group. Except for the DVD, the two groups had the same resources. The difference in scores on an exam given after a single dissection period did not differ sufficiently to conclude that DVD use raised the mean score; however, 73% of the DVD group scored 60% or higher, while only 38% of the No DVD group scored 60% or higher. The difference in mean scores overall was 2.3 points out of a possible 49, suggesting that the DVD helped students, especially those with lower scores, to earn two to three more points than they would have otherwise.

    Full Text Available Cerebral viscoelastic constants can be measured in a noninvasive, image-based way by magnetic resonance elastography (MRE for the detection of neurological disorders. However, MRE brain maps of viscoelastic constants are still limited by low spatial resolution. Here we introduce three-dimensional multifrequency MRE of the brain combined with a novel reconstruction algorithm based on a model-free multifrequency inversion for calculating spatially resolved viscoelastic parameter maps of the human brain corresponding to the dynamic range of shear oscillations between 30 and 60 Hz. Maps of two viscoelastic parameters, the magnitude and the phase angle of the complex shear modulus, |G*| and φ, were obtained and normalized to group templates of 23 healthy volunteers in the age range of 22 to 72 years. This atlas of the anatomy of brain mechanics reveals a significant contrast in the stiffness parameter |G*| between different anatomical regions such as white matter (WM; 1.252±0.260 kPa, the corpus callosum genu (CCG; 1.104±0.280 kPa, the thalamus (TH; 1.058±0.208 kPa and the head of the caudate nucleus (HCN; 0.649±0.101 kPa. φ, which is sensitive to the lossy behavior of the tissue, was in the order of CCG (1.011±0.172, TH (1.037±0.173, CN (0.906±0.257 and WM (0.854±0.169. The proposed method provides the first normalized maps of brain viscoelasticity with anatomical details in subcortical regions and provides useful background data for clinical applications of cerebral MRE.

  9. Coronary Artery Anomalies in Animals

    Full Text Available Coronary artery anomalies represent a disease spectrum from incidental to life-threatening. Anomalies of coronary artery origin and course are well-recognized in human medicine, but have received limited attention in veterinary medicine. Coronary artery anomalies are best described in the dog, hamster, and cow though reports also exist in the horse and pig. The most well-known anomaly in veterinary medicine is anomalous coronary artery origin with a prepulmonary course in dogs, which limits treatment of pulmonary valve stenosis. A categorization scheme for coronary artery anomalies in animals is suggested, dividing these anomalies into those of major or minor clinical significance. A review of coronary artery development, anatomy, and reported anomalies in domesticated species is provided and four novel canine examples of anomalous coronary artery origin are described: an English bulldog with single left coronary ostium and a retroaortic right coronary artery; an English bulldog with single right coronary ostium and transseptal left coronary artery; an English bulldog with single right coronary ostium and absent left coronary artery with a prepulmonary paraconal interventricular branch and an interarterial circumflex branch; and a mixed-breed dog with tetralogy of Fallot and anomalous origin of all coronary branches from the brachiocephalic trunk. Coronary arterial fistulae are also described including a coronary cameral fistula in a llama cria and an English bulldog with coronary artery aneurysm and anomalous shunting vessels from the right coronary artery to the pulmonary trunk. These examples are provided with the intent to raise awareness and improve understanding of such defects.

  10. The anatomy competence score: a new marker for anatomical ability.

    2012-01-01

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

    Victor Papilian was born an artist, during high school he studied music in order to become a violinist in two professional orchestras in Bucharest. Later on he enrolled in the school of medicine, being immediately attracted by anatomy. After graduating, with a briliant dissertation, he became a member of the faculty and continued to teach in his preferred field. His masters, Gh. Marinescu and Victor Babes, proposed him for the position of professor at the newly established Faculty of Medicine of Cluj. Here he reorganized the department radically, created an anatomy museum and edited the first dissection handbook and the first Romanian anatomy (descriptive and topographic) treatise, both books received with great appreciation. He received the Romanian Academy Prize. His knowledge and skills gained him a well deserved reputation and he created a prestigious school of anatomy. He published over 250 scientific papers in national and international journals, ranging from morphology to functional, pathological and anthropological topics. He founded the Society of Anthropology, with its own newsletter; he was elected as a member of the French Society of Anatomy. In parallel he had a rich artistic and cultural activity as writer and playwright: he was president of the Transylvanian Writers’ Society, editor of a literary review, director of the Cluj theater and opera, leader of a book club and founder of a symphony orchestra.

    1996-06-01

    A mastery of human anatomy and physiology requires a familiarity with a vast number of details about the human body. A directed method of case analysis is described that helps students deepen and solidify their understanding of anatomical and physiological facts, concepts, and principles. The successful case had four distinctive features as follows: clear learning objectives, a concise and informative scenario, straightforward and didactic questions, and an emphasis on information readily available to the student. A directed case study is presented, and its salient features are described. A procedure for integrating case analyses into an undergraduate anatomy and physiology course is outlined. Student response to this type of case study suggests that this method improves the ease of learning, the depth of learning, and an appreciation of the relevance of and a curiosity about anatomy and physiology. The addition of case analyses to a two-semester integrated course in anatomy and physiology was also associated with an improvement in exam performance. The regular use of directed case analysis is a valuable addition to the traditional methods of lecture, textbook reading, and laboratory for the teaching of human anatomy and physiology.

  13. RETHINKING THE ANIMATE, RE-ANIMATING THOUGHT

    Directory of Open Access Journals (Sweden)

    Tim Ingold

    2013-12-01

    Full Text Available Animism is often described as the imputation of life to inert objects. Such imputation is more typical of people in western societies who dream of finding life on other planets than of indigenous peoples to whom the label of animism has classically been applied. These peoples are united not in their beliefs but in a way of being that is alive and open to a world in continuous birth. In this animic ontology, beings do not propel themselves across a ready-made world but rather issue forth through a world-in-formation, along the lines of their relationships. To its inhabitants this weather-world, embracing both sky and earth, is a source of astonishment but not surprise. Re-animating the ‘western’ tradition of thought means recovering the sense of astonishment banished from offi cial science.

    1973-01-01

    The vestibular end organs, after chemical fixation, were freeze dried, coated with gold and palladium, and studied in the scanning microscope. Scanning microscopy gives a good three dimensional view of the sensory areas and allows study of both gross anatomy and microstructures. Cross anatomical features of the structure of the ampullae are demonstrated. The form of the statoconia in different species of animals is shown. New aspects of the structure of the sensory hairs are revealed. The hair bundles in the central areas of the cristae and in the striola of the maculae differ structurally from the hair bundles at the periphery of the sensory regions. Furthermore, some hair bundles consisting of very short stereocilia were observed. The relationship between the cupula and the statoconial membrane to the epithelial surface is discussed.

  19. Phylogenetic and functional implications of the ear region anatomy of Glossotherium robustum (Xenarthra, Mylodontidae) from the Late Pleistocene of Argentina

    Several detailed studies of the external morphology of the ear region in extinct sloths have been published in the past few decades, and this anatomical region has proved extremely helpful in elucidating the phylogenetic relationships among the members of this mammalian clade. Few studies of the inner ear anatomy in these peculiar animals were conducted historically, but these are increasing in number in recent years, in both the extinct and extant representatives, due to wider access to CT-scanning facilities, which allow non-destructive access to internal morphologies. In the present study, we analyze the extinct ground sloth Glossotherium robustum and provide a description of the external features of the ear region and the endocranial side of the petrosal bone, coupled with the first data on the anatomy of the bony labyrinth. Some features observable in the ear region of G. robustum (e.g., the shape and size of the entotympanic bone and the morphology of the posteromedial surface of the petrosal) are highly variable, both intraspecifically and intraindividually. The form of the bony labyrinth of G. robustum is also described, providing the first data from this anatomical region for the family Mylodontidae. The anatomy of the bony labyrinth of the genus Glossotherium is here compared at the level of the superorder Xenarthra, including all available extant and extinct representatives, using geometric morphometric methods. In light of the new data, we discuss the evolution of inner ear anatomy in the xenarthran clade, and most particularly in sloths, considering the influence of phylogeny, allometry, and physiology on the shape of this highly informative region of the skull. These analyses show that the inner ear of Glossotherium more closely resembles that of the extant anteaters, and to a lesser extent those of the giant ground sloth Megatherium and euphractine armadillos, than those of the extant sloths Bradypus and Choloepus, further demonstrating the striking

    This article highlights some key areas where economics can contribute to the current debate about animal welfare. Production economics reveals that producers will not maximize animal welfare, even if animal well-being is highly correlated with output. Welfare economics raises thorny issues about the double-counting of benefits when humans exhibit altruism towards animals, while public economics uncovers potential market failures and possible solutions. Consumer economics provides a means of d...

    Petroclival meningiomas are a challenge for neurosurgeons due to the complex anatomy of the region that is rich of vessels and nerves. A perfect and detailed knowledge of the anatomy is very demanding in neurosurgery, especially in skull base surgery. The authors describe the microsurgical anatomy to perform an anterior petrosectomy based on their anatomical and surgical experience and perform a literature review. The temporal bone is the most complex and fascinating bone of skull base. The apex is located in the angle between the greater wing of the sphenoid and the occipital bone. Removing the petrous apex exposes the clivus. The approach directed through the temporal bone in this anatomical area is referred to as an anterior petrosectomy. The area that must be drilled is the rhomboid fossa that is defined by the Kawase, premeatal, and postmeatal triangles. In Division of Neurosurgery - University of Turin, 130 patients, from August 2013 to September 2015, underwent surgical resection of intracranial meningiomas. In this group, we have operated 7 PCMs and 5 of these were approached performing an anterior petrosectomy with good results. In our conclusions, we feel that this surgery require an advanced knowledge of human anatomy and a specialized training in interpretation of radiological and microsurgical anatomy both in the dissection lab and in the operating room.

    The authors used rapid prototyping (RP) technology to create anatomically congruent models of tracheo-bronchial tree for teaching relevant bronchoscopic anatomy. Pilot study. A single level tertiary academic medical center. Two 3 dimensional (3D) models of tracheo-bronchial tree (one showing normal anatomy and another with an early take off of right apical bronchus) were recreated from Computed Tomographic images using RP technology. These images were then attached to mannequins and examined with a flexible fiberoptic bronchoscope (FFB). These images were then compared with the actual FFB images obtained during lung isolation. The images obtained through the 3D models were found to be congruent to actual patient anatomy. RP can be successfully used to create anatomically accurate models from imaging studies. There is potential for RP to become a valuable educational tool in the future. © 2013 Elsevier Inc. All rights reserved.

    This research project seeks to meet the objective of science training by developing, assessing, and validating virtual reality as a human anatomy training medium. In ideal situations, anatomic models, computer-based instruction, and cadaver dissection are utilized to augment the traditional methods of instruction. At many institutions, lack of financial resources limits anatomy instruction to textbooks and lectures. However, human anatomy is three dimensional, unlike the one dimensional depiction found in textbooks and the two dimensional depiction found on the computer. Virtual reality is a breakthrough technology that allows one to step through the computer screen into a three dimensional world. This technology offers many opportunities to enhance science education. Therefore, a virtual testing environment of the abdominopelvic region of a human cadaver was created to study the placement of body parts within the nine anatomical divisions of the abdominopelvic region and the four abdominal quadrants.

    1993-06-01

    Venous disease of the lower extremities is common but is often misunderstood. It seems that the focus is on the exciting world of arterial anatomy and pathology, while the topic of venous anatomy and pathology comes in second place. However, venous diseases such as chronic venous insufficiency, leg ulcers, and varicose veins affect much of the population and may lead to disability and death. Nurses are often required to answer complex questions from the patients and his or her family about the patient's disease. Patients depend on nurses to provide accurate information in terms they can understand. Therefore it is important to have an understanding of the normal venous system of the legs before one can understand the complexities of venous diseases and treatments. This presents an overview of normal venous anatomy and physiology.

    2015-03-01

    The lateral lumbar interbody fusion approach (LLIF), which encompasses the extreme lateral interbody fusion or direct lateral interbody fusion techniques, has gained popularity as an alternative to traditional posterior approaches. With rapidly expanding applications, this minimally invasive surgery (MIS) approach is now utilized in basic degenerative pathologies as well as complex lumbar degenerative deformities and tumors. Given the intimate relationship of the psoas muscle, and hence the lumbar plexus, to this MIS approach, several authors have examined the surgical anatomy of this approach. Understanding this regional neural anatomy is imperative given the potential for serious injuries to both the motor and sensory nerves of the lumbar plexus. In this review, we critically and comprehensively discuss all published studies detailing the surgical anatomy of the lateral lumbar approach with respect to the MIS LLIF techniques. This is a timely review given the rapidly growing number of surgeons utilizing this technique. Copyright © 2014 Elsevier Ltd. All rights reserved.

    2012-01-01

    Full Text Available Introduction: Knowledge of root canal morphology is essential for successful endodontic therapy. Failure to recognize unusual root canal anatomy may lead to unsuccessful endodontic treatment. Case Report: This case report describes the successful endodontic treatment of the maxillary central incisor with unusual anatomy of two roots and two root canals. A 23-year-old male patient was referred for dental consultation with discoloration of the maxillary right central incisor with periapical lesion, which revealed unusual anatomy of root on radiographic examination, and was confirmed upon exploration. Discussion: As described by Vertucci, the maxillary central incisor presents a single root and single root canal in 100% of the cases. However, few cases of maxillary central incisors with two canals were reported in the literature, most of which were associated with developmental anomalies like fusion, germination or dens invaginatus. Clinician should be aware of the unusual anatomical variations that should be detected by the different diagnostic resources available.

    This is a major subject since the aim is to grant human beings physical, mental, social and spiritual well-being without forgetting the sacred rights of all animals. Most international codes dealing with health-related research practices state that research developed in human beings should be based on previous lab animal experiments or on other scientific data. This article aimed at explaining ethics in animal experiments. The concepts of dissertation and thesis, experimental thesis, experimental essay or pilot experiment and experimental animal facilities are reviewed. Then, a historical retrospective is drawn about the first attempt to develop experimental research policies during the mid 19th Century, in London. It is highlighted that some criteria defined by that time still persist. The first animal research ethical committee was created in Sweden in 1979, followed by the USA in1984. In Brazil, animal research ethical committees were created as late as in the 90s. The Federal Law 6638 was passed in May 1979 and provides for the didactic-scientific practice of animal vivisection. This law, however, is still waiting for regulation. In addition, there are some drafts being analyzed by the Congress, which provide for the use of animals for teaching and research purposes. Finally, the policies adopted by the Brazilian College of Animal Experiments and the Universal Declaration of Animal Rights are presented. Professors, postgraduates, residents and graduate students of a Medical School involved in animal research should be aware of the ethical principles aiming at protecting animals selected for scientific work.

    Preoperative imaging is indicated to discriminate patent, adequate superficial veins of the upper limbs undetectable by clinical inspection that could be anastomosed for the creation of a durable and functional hemodialysis fistula. The aim of this pictorial review is to provide a venous anatomic map of the upper limbs using MR venography (MRV) which could help surgeons before creation of hemodialysis access fistulas (AVF). At the level of the forearm, the antebrachial cephalic vein is the most commonly identified as patent. At the level of the elbow and distal arm, the cephalic vein is patent in 80% of normal subjects, and less often patent (23-26%) than basilic vein (33-38%) in patients. Overall, reading transaxial MR views can help for assessing upper limb vein anatomy before creation of a hemodialysis access fistula. (orig.)

    2012-01-01

    The use of online social networks in medical education can remodel and enhance anatomy teaching and learning; one such network is the video-sharing site YouTube. Limited research in the literature exists on the use of YouTube as a platform for anatomy education. The aim of this study is to assess student's perceptions and patterns of usage of this resource, as well as the effectiveness of YouTube videos within a problem-based learning (PBL) curriculum. The study was conducted on 91 second-year medical students for whom video links were suggested throughout the academic year. In addition, the Human Anatomy Education (HAE) Channel was launched on YouTube to support classroom teaching with videos that emphasized applied aspects of anatomy. The results demonstrated that 98% of the students used YouTube as an online information resource, albeit in different frequencies. Out of the 86% who have been to the HAE Channel, 92% agreed/strongly agreed that the channel helped them learn anatomy. The study also reports the popularity of and awareness about using YouTube as a social network as well as in learning. Based on these findings, YouTube can be considered as an effective tool to enhance anatomy instruction if the videos are scrutinized, diversified, and aimed toward course objectives. Faculty of average computer literacy should be enabled to produce videos on their own YouTube channels to support independent learning and integration in a PBL curriculum. The methods described for capturing and editing the videos can be used as a prototype. Copyright © 2012 American Association of Anatomists.

    The use of cadavers in human anatomy teaching requires adequate number of anatomy instructors who can provide close supervision of the students. Most medical schools are facing challenges of lack of trained individuals to teach anatomy. Innovative techniques are therefore needed to impart adequate and relevant anatomical knowledge and skills. This study was conducted in order to evaluate the traditional teaching method and reciprocal peer teaching (RPT) method during anatomy dissection. Debriefing surveys were administered to the 227 first year medical students regarding merits, demerits and impact of both RPT and Traditional teaching experiences on student's preparedness prior to dissection, professionalism and communication skills. Out of this, 159 (70 %) completed the survey on traditional method while 148 (65.2 %) completed survey on RPT method. An observation tool for anatomy faculty was used to assess collaboration, professionalism and teaching skills among students. Student's scores on examinations done before introduction of RPT were compared with examinations scores after introduction of RPT. Our results show that the mean performance of students on objective examinations was significantly higher after introduction of RPT compared to the performance before introduction of RPT [63.7 ± 11.4 versus 58.6 ± 10, mean difference 5.1; 95 % CI = 4.0-6.3; p-value learning environment of the dissection groups was very active learning during RPT sessions and that professionalism was observed by most students during discussions. Introduction of RPT in our anatomy dissection laboratory was generally beneficial to both students and faculty. Both objective (student performance) and subjective data indicate that RPT improved student's performance and had a positive learning experience impact. Our future plan is to continue RPT practice and continually evaluate the RPT protocol.

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

    The aim of this study was to describe the anatomy correlated to the normal magnetic resonance imaging (MRI) images of the proximal thigh region and the ischial tuberosity. MRI coronal and axial sequences were obtained from 20 asymptomatic volunteers (10 male and 10 female) aged 20 to 38 years (mean age: 28 years), and then they were compared with 2 anatomical dissections and 7 cryosections of 6 cadaver thighs. The anatomical specimens were directly correlated with MRI scans. From the comparison it could be seen how the axial MRI sequences well outlined the sciatic nerve, usually observed oval in shape with moderate signal intensity, and thus easily detectable from other surrounding organs. Other structures were also identified by axial images: the ischial tuberosity, the proximal origin of the hamstring muscles arising from the ischium and the related bursae, the gluteus maximus and its bursa, the quadratus femoris and its inconstant bursa, a triangular adipose body and vessels. Coronal scans also showed well the hamstring muscles, both in length and thickness. Both MRI images and cadaver dissections showed the ischial tuberosity as an interesting intersection area that could be delimited as follows: on the dorsal border the gluteus maximus and its bursa, on the dorso-medial side the hamstring muscle origin, and on the antero-lateral side the quadratus femoris muscle with its inconstant bursa and the ischial tuberosity. These anatomical and MRI descriptions are very useful to give a contribution to the right explanation of sciatic symptoms caused by those sports specifically overloading the hamstring muscles. Frequently, in fact, in these athletes a sciatic syndrome arise drawing the physician's attention to the lumbosacral joint or to the sciatic nerve course near the piriformis muscle. Another very important site where the sciatic symptoms can rise, indeed, could also be found in the hamstring muscle region, where the nerve run under the gluteus maximus beside

    Full Text Available Smilax L. in Brazil is represented by 32 taxa and it is a taxonomically difficult genus because the plants are dioecious and show wide phenotypic variation. The analysis and use of leaf anatomy characters is recognized as a frequently successful taxonomic method to distinguish between individual taxon, when floral material is absent or minute differences in flowers and foliage exist such as in Smilax. The aim of this study was to characterize the anatomical features of the aerial organs in Smilax syphilitica collected from the Atlantic Rainforest, in Santa Teresa-ES and the Smilax aff. syphilitica from the Amazon Rainforest, in Manaus, Brazil. For this, a total of three samples of Smilax were collected per site. Sample leaves and stems were fixed with FAA 50, embedded in historesin, sectioned on a rotary microtome, stained and mounted in synthetic resin. Additionally, histochemical tests were performed and cuticle ornamentation was analyzed with standard scanning electron microscopy. S. syphilitica and S. aff. syphilitica differed in cuticle ornamentation, epidermal cell arrangement and wall thickness, stomata type and orientation, calcium oxalate crystal type, and position of stem thorns. Leaf blades of S. syphilitica from the Amazon Rainforest have a network of rounded ridges on both sides, while in S. aff. syphilitica, these ridges are parallel and the spaces between them are filled with numerous membranous platelets. Viewed from the front, the epidermal cells of S. syphilitica have sinuous walls (even more pronounced in samples from the Amazon; while in S. aff. syphilitica, these cells are also sinuous but elongated in the cross-section of the blade and arranged in parallel. Stomata of S. syphilitica are paracytic, whereas in S. aff. syphilitica, are both paracytic and anisocytic, and their polar axes are directed towards the mid-vein. Calcium oxalate crystals in S. syphilitica are prisms, whereas in S. aff. syphilitica, crystal sand. Thorns

    An interdisciplinary survey of a subtropical intrathermocline eddy was conducted within the Canary Eddy Corridor in September 2014. The anatomy of the eddy is investigated using near submesoscale fine resolution two-dimensional data and coarser resolution three-dimensional data. The eddy was four months old, with a vertical extension of 500 m and 46 km radius. It may be viewed as a propagating negative anomaly of potential vorticity (PV), 95% below ambient PV. We observed two cores of low PV, one in the upper layers centered at 85 m, and another broader anomaly located between 175 m and the maximum sampled depth in the three-dimensional dataset (325 m). The upper core was where the maximum absolute values of normalized relative vorticity (or Rossby number), |Ro| =0.6, and azimuthal velocity, U=0.5 m s-1, were reached and was defined as the eddy dynamical core. The typical biconvex isopleth shape for intrathermocline eddies induces a decrease of static stability, which causes the low PV of the upper core. The deeper low PV core was related to the occurrence of a pycnostad layer of subtropical mode water that was embedded within the eddy. The eddy core, of 30 km radius, was in near solid body rotation with period of 4 days. It was encircled by a thin outer ring that was rotating more slowly. The kinetic energy (KE) content exceeded that of available potential energy (APE), KE/APE=1.58; this was associated with a low aspect ratio and a relatively intense rate of spin as indicated by the relatively high value of Ro. Inferred available heat and salt content anomalies were AHA=2.9×1018 J and ASA=14.3×1010 kg, respectively. The eddy AHA and ASA contents per unit volume largely exceed those corresponding to Pacific Ocean intrathermocline eddies. This suggests that intrathermocline eddies may play a significant role in the zonal conduit of heat and salt along the Canary Eddy Corridor.
