RESUMO

Under the futuristic vision of anatomical sciences, a strong societal connection is mandatory. The anatomical practice experienced robust societal participation through public human dissection from the 16th century onward. With a perspective to explore the intersection of spirituality with anatomy, the present study analyzed this momentous period. From a spiritual perspective, the study also reflects on two relevant but presently uncoupled entities of public human dissection and societal connection through the prism of current regulations. Strong representation from the general public during public human dissection was primarily driven by spiritual proclivity and an endorsement from religious authorities. To regulate large gatherings and maintain academic sanctity, anatomical theaters emerged as dedicated spaces for such a merger. With time and growing financial support, the theaters transformed from temporary structures to elaborate architectural marvels, further propelling already robust societal connections associated with the practice. Nevertheless, a confluence of multiple factors led to the violation of spiritual principles and a consequent decrease in societal participation from the early 18th century, eventually culminating in the demise of such spectacle. Presently, public human dissection-when done-is mostly conducted for commercial gains and in contravention of ethical norms. It is against the essence of spirituality and harbors a bleak prospect for societal connection. Contrastingly, measures adopted to promote societal participation (mostly related to body donation) were quite effective and followed the principles of spirituality. Societal connections served anatomy in the past and can lead to its advancement if approached through a righteous path.

RESUMO

The nervous system is distinctive as compared to other tissue systems in human body owing to intricate structural organization. Histological studies played a key role in unveiling complex details of nervous tissue. However, the process of developing suitable staining method for nerve cells was arduous and spanned across almost half a century. The present study explored details of the journey involving quest for propitious staining method in neuroanatomy culminating in promulgation of neuron doctrine at the onset of 20th century. Initial efforts involving hematoxylin (including its diverse modifications) and subsequent adoption of analogous dye-based stains (like Nissl's method) had limited success in visualization of different parts of a nerve cell and structural details of nervous tissue. This was due to inability of dye-based stains to penetrate the connective tissue sheath of nervous tissue. Eventually, advent of metallic stains in form of silver impregnation method (Golgi stain), reduced silver impregnation method with gold stain (Cajal's stain) and silver carbonate staining method of Río-Hortega unraveled the structure of nervous tissue. The evolution of staining methods catalyzed the refinement of theories pertinent to constitution of nervous tissue. Golgi's staining led to emergence of reticular theory (neurons exist as a network) and Nissl's staining was the basis of the concept of Nervösen Grau (nerve cells and glial cells are embedded in mass of gray matter). Finally, Cajal's staining method successfully elucidated the complex anatomy of nerve terminals and resulted in emanation of neuron doctrine (neurons exists as individual units with adjacent connections).

RESUMO

Responsible Research involves setting moral examples before fellow academicians and the society as a whole. The concept of Responsible Research applies appropriately to ethical sourcing and handling of human tissues. The present study was undertaken to analyze present situation regarding implementation of attributes of Relevant Research in relation to body donors in anatomical research. A literature search of relevant, peer-reviewed, published articles was undertaken from indexed databases (Medline & PubMed, Scopus, Embase, CINAHL Plus, Web of Science and Google Scholar) for this study. The following attributes of Responsible Research were identified for possible intervention: the fact that research was conducted on human tissues from body donors and details regarding ethical handling thereof may be explicitly mentioned in method section; expression of gratitude towards body donors by authors may be included in acknowledgement section; editor's and publisher's note in support of adoption of attributes of Responsible Research may be included in published research. Adherence to best practices in terms of ethical guidelines requires anatomists to embrace a responsible approach in research from an inclusive perspective. Accordingly, practice of acknowledging the body donors may be nurtured and augmented to include the anonymised dead (human tissues from unclaimed bodies and unknown source) provided the research protocol received clearance from authorities concerned with ethical scrutiny. Moreover, adoption of the practice in review articles will enhance the boundaries of Responsible Research in anatomical science. Thus, few recommendations are proposed as epilogue for effectual implementation of the notion floated in present study.

RESUMO

Anatomy has always been at the intersection of the socio-cultural and political landscape, where new ideas constantly replace older wisdom. From ancient Egyptians through the Greeks, and then the Romans, finally culminating into the European Renaissance-all the significant eras of human civilisation have left their insignia and distinct marks on the evolution of anatomical practices. Despite its utility as a tool for anatomy pedagogy and research that has proven its worth over millennia, cadaveric dissection has particularly been subject to political and social vicissitudes. A major debate about anatomical dissection lay with the ethical considerations, or its lack thereof, while acquiring corpses for demonstration in the dissection halls. From antiquity, anatomical dissection-often synonymous with medical studies-had typically been carried out on the dead bodies of executed criminals with certain laws, such as the Murder Act of 1752, facilitating such uses. Gradually, the uses of unclaimed bodies, resourced primarily from the impoverished sections of society, were also introduced. However, these body acquisition protocols often missed the crucial element of humanism and ethical considerations, while knowledge augmentation was taken as sufficient reasoning. Unfortunately, a gross disregard towards humanistic values promulgated heinous and illegal practices in acquiring corpses, including grave robbery and even murders like in the case of Burke and Hare murders of 1828. Follow-up legislation, such as the Anatomy Act of 1832, and comparable laws in other European nations were passed to curb the vile. What distils from such a historical discourse on humane values in anatomy dissection, or medical science in general, is that the growth and integration of humanism in anatomy have never been linear, but there were intermittent and, yet, significant disruptions in its timeline. For example, there were serious human rights violations in anatomical practices during the Third Reich in Germany that perpetrated the holocaust. The medical community has kept evolving and introducing new moral values and principles while using such egregious events as lessons, ultimately resulting in the Declaration of Helsinki in 1964. This article revisits the heterogeneous journey of integrating humanistic values in anatomy practice. Such humanistic traits that, like medical science, have also developed over centuries through the inputs of physicians, researchers, and philosophers-from Greece to modernity with an important stopgap at the Renaissance-are a fascinating lore that deserves to be re-envisioned through the lens of contemporary values and ethos. In parallel to human medicine, humanistic values continue to influence veterinary medicine, a welcome development, as our society condemns animal cruelty in any form. There are lessons to be learned from this historical journey of how humanism shaped many of the concepts that anatomists use now. Finally, and most importantly, it might prevent the medical community from repeating the same mistakes by cautioning against the traps that are there, and in a convoluted world where morality as such is eroding from our social fabric, will always be there. Such historical account acts as a righteous, ethical, and contextual compass to guide the existing and upcoming anatomists in discerning between light and dark, right and wrong, and roads-to be or not to be-taken.

RESUMO

The concept of evidence-based anatomy (EBA) emerged in 2014 and has become a significant element in contemporary anatomy education. The evolving fabric of the medical education curriculum has necessitated critical changes in practice. EBA enables these changes to be incorporated seamlessly and implemented congruently into anatomy education programs. However, in parallel, non-evidence-based (classical) knowledge that has been built up through centuries of anatomical practice continues to be the core element of anatomy education in some countries/regions. Its inherent limitations hinder integration with clinical practice, leading to a rise in misadventures in the clinical setting. This viewpoint commentary highlights the strengths of EBA vis-à-vis the related attributes of classical anatomy. Appropriate arguments show that EBA helps to reduce cognitive load and enables knowledge to be delivered through innovative education tools. EBA also helps to create an inclusive learning environment in a technology-driven era. Moreover, empowered by robust resources, it is driving the pertinent amalgamation of anatomy knowledge with clinical practice. This viewpoint article endorses the adoption of EBA in contemporary anatomy education on the basis of its potential for shaping future anatomical practice.

RESUMO

Objective: The present study was conducted to collect morphometric data on the lumbar vertebrae pedicles of the adult population from the eastern parts of India and analyse the variations, if any, with other parts of the country and the world. Methods: The retrospective cross-sectional study where lumbar pedicle morphometric data was obtained via dried bone, the 3D Lumbar vertebrae images were obtained by scanning the dried lumbar vertebrae, and the 3D lumbar vertebrae model was generated from a 1 mm thin CT scan slice of the Lumbar spine of patients who were advised to have a CT scan of the abdomen for reasons other than related to the vertebral column. Both linear and angular measurements in the lumbar pedicles were made bilaterally. Results: The transverse pedicle width is widest at L3 and the narrowest at L2 vertebra bilaterally. The sagittal pedicle width at L4 vertebrae was observed to be the widest bilaterally, while L3 had the narrowest pedicle. The pedicular and body length along the pedicular axis is longer than the central axis at all the lumbar levels. The linear measurement along the pedicular axis was longest at L5 bilaterally via both modes, with a range of 18.2-47.31 mm for bones and 21.03-49.28 mm for CT scan morphometry. The transverse pedicular angle on analysis was observed to increase as one goes down the spine from L1 to L5, with a steep rise between L4 and L5. In contrast, the sagittal pedicular angle decreased as we went caudally toward the L5 vertebrae. Conclusion: The present study data had significant differences among the values reported in the literature from the different populations for the parameters studied. The data obtained by this study will be highly beneficial for the success of the free-hand technique of pedicle screw insertion.

RESUMO

BACKGROUND: The subscapularis (SSC) is the largest rotator cuff muscle and is involved in the medial rotation, abduction, adduction, and anterior stabilization of the shoulder. It is anatomically variable, as is the morphology and prevalence of the accessory SSC (aSSC), a rare muscle slip attached to the SSC. There is no current review investigating the prevalence and morphometrics of the SSC and aSSC. PURPOSE: To investigate the prevalence of the morphological variants of the SSC and aSSC via meta-analysis and review the relevant literature involving cadaveric, magnetic resonance imaging, and ultrasonographic studies. STUDY DESIGN: Meta-analysis. MATERIALS AND METHODS: Literature data reporting the prevalence rates and morphometrics of the SSC and aSSC and their variants were pooled. Literature searches and data analyses were performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses and Anatomical Quality Assurance guidelines. RESULTS: Forty-six studies, totaling 2166 shoulders, were assessed. The SSC showed an overall length, thickness, cross-sectional area, and volume of 152.2 mm (95% confidence interval, CI, 103.8-200.5 mm), 5.6 mm (95% CI, 4.6-6.6 mm), 18.1 cm2 (95% CI, 14.2-22.0 cm2 ), and 126.9 cm3 (95% CI, 87.2-166.5 cm3 ), respectively. The SSC displayed substantial variations in its origin and insertion points and in the composition of its tendon. The aSSC had an overall pooled prevalence of 24.6% (95% CI, 0.0%-76.9%). CONCLUSIONS: The SSC and aSSC have been implicated in multiple shoulder pathologies, including muscle and tendon ruptures and neurovascular compromise. A better understanding of SSC and aSSC variants when diagnosing and treating their related pathologies will reduce patient morbidity and improve treatment regimens.

RESUMO

Johannes Nathanael Lieberkühn was a prodigious anatomist whose meticulous experiments and precise detailing helped in comprehending the microscopic anatomy of digestive system during early part of eighteenth century. Notably, his inventions in the field of microscopy aptly complemented his quest for anatomical knowledge at microscopic level. He designed a reflector (Lieberkühn reflector) which enhanced the amount of focussed light leading to bright illumination of tissue specimen. He invented the solar microscope which provided excellent resolution of minute anatomical details. Lieberkühn discovered the digestive juice secreting tubular glands (glands of Lieberkühn) present at the base of intestinal villi producing epithelial invaginations (crypts of Lieberkühn). He also described the intricate juxtaposition of blood vessels in relation to a single intestinal villi. Moreover, through empirically designed experimental set up, Lieberkühn was able to demonstrate the flow of lymph from intestinal villi to collecting lymphatic vessels. Also, his grandiose collection of laboratory specimens involving vascular anatomy are a testimony of his untiring efforts in academia. His contributions were seminal in comprehending the anatomy of digestive system and paved the way for future revelations. His work unveiled the enormous scope of microanatomy in medical science and catalysed the advent of histological staining methods a century later.

RESUMO

The Covid-19 pandemic stipulated adoption of unfamiliar strategies for delivering anatomy education in online mode. The factors which determine education strategies are variable across geographical regions. It was perceived that an overview of education strategies around the globe would be useful for anatomists. Hence this narrative review was undertaken to collate observations from different geographical regions pertaining to education strategies adopted during the pandemic. Data relevant to the topic of study were extracted from 12 articles that were selected from an initial pool of 317 articles based on search criteria set for the review. Subtle differences in core education strategies implied that baseline response from anatomists was similar across regions. It was evident that online digital tools were key elements of education strategies adopted by educators for delivering online anatomy classes across the globe. Interestingly, a considerable gap in terms of number and variety of online tools used for anatomy education (those requiring commercial purchase) was noted between economically developed and developing regions. This may have an impact on learning outcome for students and may even lead to variations in anatomical knowledge by regions. It was observed that offline human dissection sessions were incorporated into online practical classes in one region as positive cases showed a declining trend. This positive development is worth emulating elsewhere based on cautious assessment of prevailing situation. From a broad perspective timely introduction of education strategies ensured delivery of anatomy education during the pandemic and gave an evolved outlook to the fabric of anatomy education.

RESUMO

INTRODUCTION: Anatomical sciences involve handling of human tissues and, therefore, application of principles of bioethics is central to anatomical practice. For a considerable period of time, anatomy was practiced without ethical norms as concept of ethics developed during second half of twentieth century. Hence, possible glimpse into contrast in ethical standards between anatomy in the past and present was deemed as an intriguing research theme. METHODS: A literature search was undertaken from indexed databases (Medline and Pubmed, Scopus, Embase, CINAHL Plus, Web of Science and Google Scholar). Relevant data were extracted from 37 articles that were selected from an initial pool of 752 articles based on search criteria set for the study. RESULTS: Prevalent anatomical practices in the past such as dissection of executed criminals, acts of vivisection, illegal procurement of human remains, use of human tissues obtained as part of war crimes and dissection of human fetuses as well as their archival were analyzed through prism of established ethical norms in present day. The observations from past were presented vis-à-vis ethical practices undertaken in present times such as use of donated bodies and/or body parts procured through legal means for dissection, adherence to ethical norms during dissection, archival of human tissues mandating stringent regulation and dignified disposal of human remains. Existing loop holes were identified and future prospects regarding ethical standards in anatomy were highlighted based on rational judgment of existing trends. CONCLUSION: The article concludes with defense on future prospects of ethics in anatomy based on documented arguments.

RESUMO

INTRODUCTION: Recent systematic reviews highlighted increasing use of cadaveric models in the surgical training, but reports on the characteristics of the models and their impact on training are lacking, as well as standardized recommendations on how to ensure the quality of surgical studies. The aim of our survey was to provide an easy guideline that would improve the quality of the studies involving cadavers for surgical training and research. METHODS: After accurate literature review regarding surgical training on cadaveric models, a draft of the CACTUS guidelines involving 10 different items was drawn. Afterwards, the items were improved by questionnaire uploaded and spread to the experts in the field via Google form. The guideline was then reviewed following participants feedback, ergo, items that scored between 7 and 9 on nine-score Likert scale by 70% of respondents, and between 1 and 3 by fewer than 15% of respondents, were included in the proposed guideline, while items that scored between 1 and 3 by 70% of respondents, and between 7 and 9 by 15% or more of respondents were not. The process proceeded with Delphi rounds until the agreement for all items was unanimous. RESULTS: In total, 42 participants agreed to participate and 30 (71.4%) of them completed the Delphi survey. Unanimous agreement was almost always immediate concerning approval and ethical use of cadaver and providing brief outcome statement in terms of satisfaction in the use of the cadaver model through a short questionnaire. Other items were subjected to the minor adjustments. CONCLUSION: 'CACTUS' is a consensus-based guideline in the area of surgical training, simulation and anatomical studies and we believe that it will provide a useful guide to those writing manuscripts involving human cadavers.

RESUMO

The suprarenal arteries are arising from three sources: superior suprarenal artery, middle suprarenal artery, and inferior suprarenal artery. Variations in the arterial supply of the suprarenal glands in respect to origin and number are quite common and very frequently reported. The most common variation noted is in the inferior suprarenal artery followed by the middle suprarenal artery and the least common variations were observed in the superior suprarenal artery. Arteriogram of the inferior suprarenal artery is crucial in suprarenal tumour diagnosis but variation in the branching pattern and multiplicity of these arteries can cause hindrance in arteriography. The absence of middle suprarenal artery was seen to be associated with increased number of the inferior suprarenal artery. Variation in the multiplicity of arteries was observed more frequently in the inferior suprarenal artery and middle suprarenal artery which was more on the right side in most of the studies. Also, the variation in suprarenal arteries was often correlated to variations in inferior phrenic and gonadal arteries. The variations were observed to be more common on the left side therefore right adrenalectomy should be preferred over the left one. The loop formed by the inferior suprarenal artery around the right renal vein can cause venous obstruction. These variations of suprarenal vasculature are explained on the developmental basis, and prior knowledge of such variants is crucial for nephrologists to ensure minimum blood loss while performing laparoscopic adrenalectomy especially for large adrenal tumours and pheochromocytoma where the duration of surgery exceeds the usual.

RESUMO

Present day scenario regarding epistemological methods in anatomy is in sharp contrast to the situation during ancient period. This study aimed to explore the evolution of epistemological methodologies in anatomy across centuries. In ancient times Egyptian embalmers acquired anatomical knowledge from handling human bodies and likewise anatomical studies in India involved human dissection. Ancient Greeks used theological principles-based methods, animal dissection and human dissection in practice of anatomy. Human dissection was also practiced in ancient China for gaining anatomical knowledge. Prohibition of human dissection led to use of animal dissection in ancient Rome and the trend continued in Europe through Middle Ages. Epistemological methods used by Muslim scholars during Middle Ages are not clearly chronicled. Human dissection returned as primary epistemological method in Renaissance Europe and empirical methods were reinstated after ancient period in human dissection during 16th century. The situation further improved with introduction of pragmatic experiment based approach during 17th century and autopsy-based methods during 18th century. Advances in anatomical knowledge continued with advent of microscope-based methods and emergence of anatomical sections in practice of human dissection in 19th century. Introduction of human observational studies, medical imaging, and molecular methods presented more options in terms of epistemological methods for investigating the human body during 20th century. Onset of 21st century has witnessed dominance of technology-based methods in anatomy. Limited emphasis on ethics in epistemological methodologies since antiquity is a dark aspect of otherwise an eventful evolutionary journey but recent developments are in positive direction.

RESUMO

INTRODUCTION: In view of the ongoing COVID-19 pandemic, anatomy education programs were amended so as to shift to primarily online mode from physical classes. In the whole process, main concern area that has emerged is regarding dearth of physical human dissection sessions. There is enough evidence available in literature to suggest that dissection room is an ideal place to cultivate and inculcate discipline independent skills or humanistic skills among the students. These include attributes in relation to ethical practice, professionalism, communication skills, empathy and compassion. Imbibing these skills are an essential element of medical education curriculum as it is desirable that students exhibit these traits when they begin medical practice. Hence deficiency in terms of exposure to physical dissection sessions can adversely affect training of medical students on a long term. METHODS: A literature search of relevant, peer-reviewed, published articles was undertaken from indexed databases (Medline and PubMed, Scopus, Embase, CINAHL Plus, Web of Science and Google Scholar) for this study. RESULTS: To counter the pertinent issue in online anatomy teaching program, a few measures have been suggested in this paper based on identification of actual deficit areas in terms of learning and analysis thereof. Live streaming of real time dissection, awareness sessions on human dissection, online interactive learning sessions and reflective thoughts-based exercise can contribute to building discipline independent skills in present scenario. CONCLUSION: Incorporation and implementation of these interventions within the realm of online anatomy education programs during COVID-19 pandemic can possibly contribute towards desirable learning outcomes.

RESUMO

Raymond de Vieussens was an exemplary anatomist who made seminal contributions in the field of cardiology. During initial part of his academic career, he adopted human dissection based experiments as medium of his research. This was in accordance with prevailing trend among anatomists during 17th century. He discovered the presence of tiny venous tributaries communicating between cardiac veins and chambers of heart (ducti carnosi/venae cordis minimae). He reported the existence of a collateral circulatory pathway between right and left coronary arterial systems (Vieussens arterial ring). He was the first to note the valve at the junction of great cardiac vein and coronary sinus (valve of Vieussens) and the prominent oval margin of the fossa ovalis (Vieussens Annulus). All his findings were associated with considerable clinical significance as evidenced in literature that followed. Vieussens accurately demonstrated the three-layered orientation of myocardium and gave a precise description of coronary arteries and their branches. At the onset of 18th century, buoyed by royal patronage from King Louis XIV of France, the second half of Vieussens illustrious career was defined by pathologic anatomy (autopsy based) and anatomo clinical correlations. This was a new trend initiated by Vieussens in anatomical research and was later adopted as a signature method by anatomists of 18th century. As a true connoisseur of cardiologic anatomy, Vieussens accurately charted the anatomo clinical correlations of cardiac tamponade, mitral stenosis and aortic regurgitation. His contributions were pivotal elements in metamorphosis of cardiology as a robust discipline of medicine in modern times.

RESUMO

William Hunter (1718-1783) was a Scottish anatomist and physician. He started his career as a man midwife and went on to become the leading obstetrician in London. He prepared anatomically dissected specimens depicting anatomy of gravid uterus and undelivered fetus with placenta in different stages of gestation. Hunter compiled illustrations prepared from these specimens with his clinical notes and published his treatise Anatomia uteri humani gravidi in 1774. This article is a tribute to William Hunter as we approach the 250th year of publication of his work which is a significant milestone in the history of obstetrics and its practice.

RESUMO

Camillo Golgi was an extraordinary scientist whose contributions in the domain of neuroanatomy proved to be critical for emergence of neuroscience as a sovereign scientific discipline. Golgi's invention of the Black Reaction (La reazione nera) was a watershed event as it allowed remarkable visualization of the organizational pattern of elements of nervous system among complex puzzle of close knit interconnections. Till this time thin filamentary extensions of neural cells (axon and dendrites) could not be visualized with available staining techniques because of their slender and transparent nature. However invention of Black Reaction and its subsequent application demystified the basic architecture of brain tissue which was now visible to the scholars in all its complexity in microscopic studies. Golgi is also credited with the discovery of two types of sensory receptors in muscle tendons: Golgi tendon organ and Golgi-Mazzoni corpuscles. Golgi was the first to be successful in staining myelin component of axon, which he used to discover the myelin annular apparatus. He identified the complete life cycle of Plasmodium (malarial parasite) in human erythrocytes. His research on histological details of human kidney highlighted the existence of juxtaglomerular apparatus. Later on Spanish scientist Santiago Ramón y Cajal, based on the use of Golgi's Staining (Black Reaction) documented the morphologic details of nervous system in a more refined manner, which eventually led to the emergence of Neuron Doctrine. In recognition of their exemplary contributions in neuroscience Golgi and Cajal were jointly awarded the Nobel Prize for Physiology or Medicine in 1906.

RESUMO

It is a much desirable skill among physicians that clinical practice should be guided by ethical norms. The dissection room experience provides an opportunity for nurturing the principles of ethical practice among medical students early in the curriculum. When the exercise of human dissection is followed within the boundaries of ethics it effectively props an ideal example for the young minds to emulate in the future. Hence in every stage of dissection room activity precious human body needs to be handled in an ethical manner so as to set a standard for the students. The present review is an attempt to collate the recommendations documented by researchers as per ethical guidelines in the context of human dissection. The review highlights on the ethical norms which needs to be adhered to while receiving the human body of a donor and during preservation of the same. It reflects on ideal ethical behaviour in the dissection room during the act of dissection and finally emphasize on the respectful disposal of the human remains in an ethical manner. The intended purpose of this article is to support uniform adoption of the recommendations for ethical handling of human bodies used in anatomical dissection.
