Wilhelm Waldeyer as an object - Anatomists as body donors.

INTRODUCTION: Berlin anatomist Wilhelm von Waldeyer-Hartz (1836-1921) donated his skull, brain, and hands to his institute. Only the skull survives in the present-day collection. This study investigates the skull itself as much as the historical context of Waldeyer's donation. METHODS: Physical-anthropological investigation of the remains and historical research. RESULTS: Waldeyer's main motivation was the donation of his brain to science. While this was the first ever recorded body donation in Berlin, it was not unusual for scientists of his time to donate their brains and/or to investigate brains of fellow scientists to correlate brain morphology to individual traits. Nevertheless, Waldeyer's pupil Hans Virchow expressed reservations dissecting his former boss, reservations that were unknown to him when dissecting others. Waldeyer's brain was never investigated and not preserved, likely due to damage by stroke and poor anatomical fixation. Waldeyer's skull shows the common features of a male European of senile age with some notable anatomical variation including a "trigeminus bridge". DISCUSSION: Waldeyer's donation is embedded in a tradition of research looking, if in vain, for traceable signs of intelligence or geniality in brains of well-known individuals. Reservations of anatomists to dissect other anatomists and to donate their own bodies persist until today.

Revisiting the Latin vocabulary of Terminologia Histologica: I. Nouns.

Almost 20% of the Latin nouns (193/993) in Terminologia Histologica (TH), the international standard nomenclature for human histology and cytology, display linguistic problems, particularly in the areas of orthography, gender, and declension. Some anatomists have opposed efforts to restore the quality of the Latin nomenclature as pedantry, preferring to create or modify Latin words so that they resemble words in English and other modern languages. A Latin microanatomical nomenclature is vulnerable to the criticism of anachronism, so the requirement for the use of authentic Latin, including derivation of new words from Greek and Latin words rather than from modern languages, if possible, may be even greater than it is for the anatomical nomenclature. The most common problem identified here appears to have been caused by derivation of Latin nouns by addition of -us and -um second declension endings to English words. Many Latin nouns (128) in TH contain one of six morphemes that have been treated this way even though the original Greek words are either first declension masculine or third declension neuter nouns. Ironically, deriving Latin nouns directly from Greek morphemes often results in words that look more familiar to speakers of Romance and Germanic languages than those derived indirectly through modern languages (e.g., astrocyte, collagene, dendrita, lipochroma, osteoclasta and telomere instead of astrocytus, collagenum, dendritum, lipochromum, osteoclastus, and telomerus).

Typical brachial plexus: the legacy of a forgotten anatomist, Abram T. Kerr (1873-1938).

The brachial plexus, a complex network of nerves responsible for innervating the upper limb, exhibits remarkable anatomical variations. This editorial explores the composite drawing of a "typical" brachial plexus portrayed by Abram T. Kerr in 1918. This composite drawing of the typical brachial plexus stands as a critical contribution to the field of anatomy and surgery, and encapsulates the most prevalent patterns of formation, branching, and origins within the brachial plexus, offering a statistical map of its common variants. Kerr portrays the typical brachial plexus as a foundational resource for anatomists and medical professionals seeking to navigate the intricate landscape of this neural structure. It serves as a hypothetical model, reflecting the common arrangement of trunks, cords, and branches, shedding light on the typical composition of the plexus observed in most individuals. Beyond being a visual representation, the 'typical' brachial plexus provides a bridge between theoretical knowledge and practical applications, aiding in the identification of variations and deviations in surgical contexts. This composite drawing enhances our comprehension of the intricate and ever-evolving anatomy of the brachial plexus, reinforcing its role as a fundamental reference point for anatomical studies and clinical practice.

Responsible research in the practice of anatomy: Attributes relevant to body donors and human tissues sourced from them.

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.

The anatomical variability of obturator vessels: Systematic review of literature.

OBJECTIVE: To systematically assess available information about all variations of obturator vessels and to present the most surgically relevant types, their prevalence and calibre in order to provide a comprehensive overview for both anatomists and clinicians. MATERIALS AND METHODS: A total of 2689 studies were found via searching the online databases. After applying exclusion criteria 44 studies were assessed. The cadaveric studies, CT angiographies, and clinical studies were included. Number of hemipelves, prevalence of each variation and calibre of identified vessels were studied. Each variation was classified as aberrant obturator artery/vein, aberrant accessory obturator artery/vein or anastomosis. RESULTS: In included studies the average incidence of the variant obturator artery was 26% with the aberrant obturator artery being the most frequent type (with the mean calibre 2.10 mm, SD = 0.35 mm), while the overall incidence of the variant obturator vein was 55%. Presented venous structures had the mean calibre of 2.98 mm (SD = 0.56 mm). CONCLUSIONS: According to reviewed studies, variant obturator vessels are present in a great number of patients. Due to their possible calibre larger than 3 mm they represent a structure of high clinical importance. It is important to unify the terminology and to stress out the significance to all clinicians.

Assessing Chinese anatomists' perceptions and attitudes toward blended learning through faculty development training programs.

Background: As a response to the COVID-19 pandemic, the faculty development program has partially shifted to online formats over the past two years, with a specific focus on professional training related to blended learning. The effectiveness of this training is closely tied to the perceptions and acceptability of blended learning among the trainees. This study aims to evaluate the perspectives of educators on blended learning, thereby assessing the efficacy of faculty training programs. Methods: Anatomical teachers were chosen as a representative sample due to their significant presence among medical science educators. Chinese anatomists were invited to participate in a survey that gauges their attitudes and readiness for blended learning. Results: A total of 297 responses were collected, covering all provinces in mainland China. The findings from the survey demonstrate that Chinese anatomists hold learning flexibility in the highest regard among the various facets of blended learning. Meanwhile, the presence of a connected learning community emerged as a pivotal factor influencing anatomists' perceptions, explaining 14.77% of the total variance. Further analysis showed noteworthy disparities in anatomists' attitudes toward blending learning based on their job titles, mentorship guidance, and support from in-service institutions. Notably, lecturers showed a more pronounced engagement in the connected learning community than teachers with different job titles. Additionally, anatomists who received stronger institutional support showed higher proficiencies in learning management. Conclusion: This survey revealed that Chinese anatomists attribute considerable value to aspects such as learning flexibility, a connected learning community, and effective learning management within the domain of online/blended learning. Positive attitudes toward blended learning are likely to be nurtured by mentorship and institutional support, subsequently correlating with improved training outcomes. The distinctive characteristics observed among Chinese anatomists in the context of blended learning offers insights to enhance the effectiveness of faculty training programs, thereby facilitating the evolution of future teaching strategies.

Confessions of a converted anatomist: teaching without anatomical donors.

In the field of anatomy education, the debate over the superiority of learning with or without human donors is decades long and ongoing. Arguments for or against the use of human donors in anatomy education vary, depending on the healthcare discipline. Physical therapy programs have been particularly resistant to the trend away from the use of human donors. In this personal view, I present my history of anatomy education and how my perspectives on teaching and learning anatomy have changed dramatically throughout my teaching experiences. The purpose of this article is to support instructors who are creating anatomy courses for all healthcare trainees without donors, inspire those teaching with donors to incorporate other methods of instruction and evaluation, challenge educators to examine their own biases surrounding anatomy education, and provide recommendations for developing an anatomy course without human donors. Included in this article is the perspective of a practicing physical therapist who learned through human dissection and has assisted me in the development and management of the human anatomy course in our physical therapy curriculum.NEW & NOTEWORTHY This article provides an overview of how to design an anatomy course without anatomical donors for doctor of physical therapy students and includes recommendations for instructors who need to reduce or eliminate anatomical donors from their anatomy curriculum.

Anatomists' uses of human skeletons: Ethical issues associated with the India bone trade and anonymized archival collections.

Concerns have recently been expressed about the continuing availability of human bones from India, obtained originally for educational purposes but lacking the requisite informed consent that would be expected today. More generally, a broader claim is being made, namely, that the practice of using any unconsented bones in educational settings is unethical and should cease. These calls, in turn, raise broader issues regarding the availability of anonymous archival collections in anatomy museums. Although this debate centers on undergraduate anatomy teaching, much anthropological research utilizes human remains of past populations for which there can have been no consent. A suggested alternative for undergraduate teaching is the use of 3D images of human bones, rather than the bones themselves. In addressing these issues, the background to the India bone trade is assessed, and the year 1985 is pinpointed as having significant ethical weight. The cultural and ethical interests inherent in studying archival anonymous skeletal material are weighed against indiscriminate reburial. Although any use of unconsented material represents ethical compromise, account should be taken of changing ethical expectations with time. It is concluded that: there is no justification for repatriation or disposal of all bones for which specific informed consent has not been obtained; continued use of anonymous archival human bones in a professional setting is acceptable, even in the absence of informed consent, with the proviso that there are no culturally relevant groups seeking repatriation; the continued existence of bones in long-standing private collections cannot be justified since it amounts to long-term storage with no identified goals; the notion that 3D images are an ethically superior alternative to actual human bones is unsustainable, since there is an intimate connection between the bones and the 3D images.

Could the altmetrics wave bring a flood of confusion for anatomists?

Altmetrics are non-traditional metrics that can capture downloads, social media shares, and other modern measures of research impact and reach. Despite most of the altmetrics literature focusing on evaluating the relationship between research outputs and academic impact/influence, the perceived and actual value of altmetrics among academicians remains nebulous and inconsistent. This work proposes that ambiguities surrounding the value and use of altmetrics may be explained by a multiplicity of altmetrics definitions communicated by journal publishers. A root cause analysis was initiated to compare altmetrics definitions between anatomy and medical education journal publishers' websites and to determine the comparability of the measurement and platform sources used for computing altmetrics values. A scoping content analysis of data from across eight publishers' websites revealed wide variability in definitions and heterogeneity among altmetrics measurement sources. The incongruencies among publishers' altmetrics definitions and their value demonstrate that publishers may be one of the root cause of ambiguity perpetuating confusion around the value and use of altmetrics. This review highlights the need to more deeply explore the root causes of altmetrics ambiguities within academia and makes a compelling argument for establishing a ubiquitous altmetrics definition that is concise, clear, and specific.

Emil Zuckerkandl and his Dental Tubercle (Historical Note).

One of the eponyms most frequently cited in dental morphology texts, together with the Carabelli tubercle of the first permanent maxillary molars, is the Zuckerkandl tubercle of deciduous molars. However, references about Emil Zuckerkandl in the field of dental history and this particular entity are scarce. The reason this dental eponym was pushed "into the shadows" probably lies in the many other anatomical parts (including another tubercle, the pyramidal one of the thyroids), which took their names from this great anatomist.

Profiting from public dissection: A new era of unethical practices.

Historically, adverse events have reflected poorly on both the practice of dissection and the perception of the discipline of anatomy. The recent public dissection of a body donor is a regression to an unethical historical practice and was strongly denounced by anatomists around the world. The individual whose donated body was sourced from a 'for-profit" company in the United States had not given consent for a public dissection. This violates the ethics surrounding consent and body donation and potentially places the future of body donor programs in jeopardy as it compromises community frameworks around epistemic trust. Recent guiding frameworks by international anatomical associations on the ethical use of bodies have cemented the way in which body donor programs should operate. This viewpoint reflects on past and current events pertaining to public dissections and questions how these indignities may influence the public's interaction with human bodies. The authors argue that public dissection should be prohibited as it is against social mores. Social pressure should be applied to individuals or companies who wish to profit from unethical anatomical practice and legislation prohibiting public dissection should be introduced in those countries where it does not yet exist.

Payment with knowledge: A method for a training of anatomy near-peer teachers and formation of future anatomists.

Near-peer teaching has been widely implemented in medical schools and the benefits for the near-peer teachers (NPTs), the students, and the institution have been well documented. However, NPT training methods and perceptions of such have been limited. A four-year clinical anatomy and surgical training program was established (est. 2019) as part of the continuous training timeline for NPTs (n > 60 total) formation at the Universidad Autónoma de Nuevo León, in Mexico. The program provides various training courses for the NPTs according to their hierarchy, including teaching skills, professional development, psychosocial aspects, and career objectives. A "Clinical Anatomy and Surgical Training Diploma" was planned with 12 modules to aid in developing these abilities, along with a higher understanding of clinical anatomy shared by expert clinical specialists, and diverse clinical and surgical skills such as suturing, catheterization, and basic surgical procedures. The program has a completion rate of approximately 15 NPTs/year. All, while creating an environment with a sense of belonging, and facilitating mentorship between fellow NPTs and educators. Near-peer teachers develop leadership, communication, and teaching skills. The program has provided a constant source of anatomy educators, avoiding any shortage.

[Why the Wittenberg anatomist and scientist Konrad Victor Schneider (1614-1680) is also important for pneumologists]. / Warum der Wittenberger Anatom und Wissenschaftler Konrad Victor Schneider (1614­1680) auch für die Pneumologen bedeutsam ist.

The Wittenberg physician Konrad Victor Schneider (1614-1680) was the first to prove that mucus is not formed in the brain, nor is it secreted into the nasal cavity via the ethmoid bone. He recognised that there is no open anatomical connection between the brain and the nasal air space. Schneider discovered the sinonasal mucosa as the production site of mucus and thus refuted the hypothesis of cerebral mucus production and secretion by Hippocrates, Galen and Vesal. The nasal mucosa was named "membrana Schneideria" in honour of Schneider.

Latin American Anatomists' views on human body dissection and donation.

BACKGROUND: Studies abound regarding the medical students' views on the importance of anatomy and the dissection of human bodies, but little is known about the views of Latin American Anatomists. METHODS: A survey was carried out to test several hypotheses among anatomists of the Americas about how they perceive their professional identity, the use and role of dissection in their undergraduate courses, and the approval degree of bequeathing their body for anatomical teaching/research; another goal was ascertaining to what extent their attitude on these topics depended on gender, length of teaching experience and belief in the afterlife. RESULTS: One hundred and forty-five anatomists from thirteen Latin American and Caribbean Countries took the survey; 79% stated the main role of an anatomist is teaching; 34% recorded their undergraduate students dissected human cadavers as part of their anatomy lab course-undergraduates dissecting less in the less experienced anatomists' courses (p = 0.0002). Most anatomists said dissection was a training tool for undergraduate students, a tool for developing professional skills, and a tool to help control emotions-most experienced anatomists stood out from the rest saying dissection is only to teach anatomy (p < 0.001), even if such response was the least valued by them among all replies. Men differed from women in valuing dissection as a tool to help control emotions (p = 0.006); less experienced anatomists held the opposite (p < 0.0001). Approval of a close doctor-patient relationship diverged, being different between the most and the least experienced anatomists (p = 0.01). Anatomists said they would donate only their organs (44%), whole body (9%) and both organs and body (46%). Undecided anatomists about the belief in life after death were the least in favor of donation (p = 0.05).

Nazi functionary or oppositionist in disguise? The complex life of the anatomist Enno Freerksen (1910-2001).

Enno Freerksen (1910-2001) is one of the most prominent German anatomists of his time, as evidenced by numerous international awards. His political role in the Third Reich, however, remains controversial. While some authors describe him an avowed National Socialist, Karl-Werner Ratschko recently speculated about a late turn of Freerksen towards political resistance. The present work takes these contradictions as an occasion for a comprehensive source-based analysis of Freerksen's activities in the Third Reich. For the first time, a synoptic evaluation of primary sources from eight different archives is undertaken. The study is supplemented by a systematic re-analysis of all available research contributions on Freerksen. The study demonstrates that Freerksen not only joined numerous Nazi organizations - partly even before Hitler came to power -, but also took on several important functions in the Nazi apparatus and worked on National Socialist research topics (e.g. racial hygiene). It can also be shown that his steep scientific career was closely linked to his political activities. The thesis that Freerksen opposed Nazi ideology towards the end of the war, on the other hand, must be clearly rejected. On the contrary: The sources show Freerksen as a National Socialist polyfunctionary, who did not self-critically reflect on his role in the Third Reich even after 1945.

Who really needs a Metaverse in anatomy education? A review with preliminary survey results.

The term Metaverse ("meta" defined as beyond, transcendence or virtuality, and "verse" meaning universe or world) denotes a "virtual reality space" for anatomy teaching. To ascertain how many anatomists are familiar or are using this adjunct in teaching, we conducted a short survey at the 2022 annual meeting of the American Association of Clinical Anatomists (AACA). Interestingly, only six respondents (9.4%) had used a Metaverse for teaching anatomy. Moreover, the vast majority of attendees were anatomy educators or basic science faculty, but not practicing physicians/surgeons or other actively practicing health care professionals; a group where this technology has been used much more commonly. The present manuscript was authored by anatomy educators, practicing physicians and other actively practicing health care professionals with backgrounds in diverse medical fields, that is, anatomists, medical doctors, physician assistants, dentists, occupational therapists, physical therapists, chiropractors, veterinarians, and medical students. Many of these authors have used or have been exposed to a Metaverse in the clinical realm. Therefore, the aim of the paper is to better understand those who are knowledgeable of a Metaverse and its use in anatomy education, and to provide ways forward for using such technology in this discipline.
