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.

Thought, attitudes, and practices of the anatomy departments on receiving and embalming cadavers during the pandemic process / Pensamiento, actitudes y prácticas de los departamentos de anatomía sobre la recepción y embalsamamiento de cadáveres durante el proceso pandémico

SUMMARY: During the Covid-19 pandemic that has marked the last years, while governments tried to control the spread of the virus, many-body donation programs were suspended due to difficulties that could potentially be encountered. Given the low body donation acceptance rates during this period, through this study we aimed to evaluate academics' knowledge, attitudes, and behaviors in cadaver acceptance and embalming practices during the pandemic. The research population of th estudy consisted of the faculty of 112 universities in Turkey who taught in under graduate and graduate programs in the Anatomy Department in 2020. An electronic questionnaire of 24 items, including demographic data, was distributed to the participants' official e-mail addresses. In addition, support was received from the Turkish Anatomy and Clinical Anatomy Society, whose members were also approached through their official group e-mail accounts. Answers were collected from 78 (39 %) out of 200 academics. The findings of the study were under 5 headings (ınformation about cadaver donation and ımported cadavers, attitude towards ımportation of cadavers and acceptance of body donations, precautions against contagion in ımportation of cadavers and acceptance of body donations and thoughts on their adequacy, considerations for adoption of cadavers for post-graduation education, advice on avoiding contagion in cadaver embalming) were collected and analyzed. The study high lights the importance of cadaver acceptance and embalming practices for medical education to minimally continue in the post-pandemic period. It can also serve as a reference for being cautious when faced with similar situations in the future.

RESUMEN: Durante la pandemia de COVID-19, que ha marcado los últimos años, mientras los gobiernos intentaban controlar la propagación del virus, muchos programas de donación de cuerpos fueron suspendidos por las dificultades que se podían encontrar. Dadas las bajas tasas de aceptación de la donación de cuerpos durante este período, a través de este estudio buscamos evaluar el conocimiento, las actitudes y los comportamientos de los académicos en la aceptación de cadáveres y las prácticas de embalsamamiento durante la pandemia. El estudio se realizó el año 2020 en los programas de pregrado y posgrado de los Departamentos de Anatomía de 112 universidades de Turquía. Se distribuyó un cuestionario electrónico de 24 ítems, incluidos datos demográficos, a los participantes por correo electrónico oficial. Además, se recibió el apoyo de la Sociedad Turca de Anatomía y Anatomía Clínica, cuyos miembros también fueron contactados a través de las cuentas de correo electrónico de su grupo oficial. Se recopilaron respuestas de 78 (39 %) de 200 académicos. Los hallazgos del estudio se ubicaron en 5 encabezados (información sobre donación de cadáveres y cadáveres importados, actitud hacia la importación de cadáveres y aceptación de donaciones de cuerpos, precauciones contra el contagio en la importación de cadáveres y aceptación de donaciones de cuerpos y opiniones sobre su idoneidad, consideraciones para la adopción de cadáveres para la educación de posgrado y consejos para evitar el contagio en el embalsamamiento de cadáveres). El estudio destaca la importancia de la aceptación de cadáveres y las prácticas de embalsamamiento para que la educación médica continúe mínimamente en el período posterior a la pandemia. También puede servir como referencia para tenerse presente ante situaciones similares en el futuro.

The carotid and vertebral arteries discovery ­ initial findings / A descoberta das artérias carótidas e vertebrais ­ achados iniciais

The studies on the vascular system, including the cervicocephalic arteries (carotid and vertebral arteries), present a long trajectory, having their deep roots in the far past, considering the Western authors, having as representatives the Greek sages Alcmaeon, Diogenes, Hippocrates, Aristoteles, Rufus, and Galenus. They produced pivotal knowledge dissecting mainly cadavers of animals, and established solid bases for the later generations of scholars. The information assembled from these six authors makes it possible to build a quite clear picture of the vascular system, here specifically focused on the cervicocephalic arteries, and mainly of the extracranial segments. Thus, the carotid system became fairly well identified, origin, course, and name, as well as the origin of the still unnamed arteries running through the orifices of the transversal processes of the cervical vertebrae, and entering into the cranium. Almost all that was then known about human anatomy, since this period, and then throughout the Middle Ages, was extrapolated from animal dissections. This state of affairs was maintained until the 14th century, when human corpses dissections were again allowed.

Os estudos do sistema vascular, incluindo as artérias cervicocefálicas (artérias carótidas e vertebrais), apresentam um longo percurso, tendo suas raízes profundas no passado distante, considerando os autores ocidentais, tendo como representantes os doutos gregos Alcméon, Diógenes, Hipócrates, Aristóteles, Rufus e Galenus. Eles produziram conhecimento pivotal, dissecando principalmente cadáveres de animais e estabelecendo bases sólidas para as gerações futuras de estudiosos. A informação reunida desses seis autores permite construir um quadro bastante claro do sistema vascular, aqui focado especificamente nas artérias cervicocefálicas e principalmente nos seus segmentos extracranianos. Assim, o sistema carotídeo ficou bastante bem identificado, origem, trajeto e nome, assim como a origem das ainda não nomeadas artérias que percorrem os orifícios dos processos transversos das vértebras cervicais e entrando no crânio. Quase tudo que era conhecido sobre anatomia humana, desde esse período, e depois ao longo da Idade Média, foi extrapolado a partir de dissecções de animais. Esse estado de coisas foi mantido até o século 14, quando a dissecção de cadáveres humanos foi novamente permitida.

Differences of neuroanatomy education for large and small numbers of students in China and Korea / Diferencias de educación en neuroanatomía de cantidades mayores y menores de estudiantes en China y Corea

In Southern Medical University, China, 1,200 medical students study neuroanatomy every year, whereas in Ajou University, Korea, only 45 medical students study neuroanatomy. The considerable difference of student numbers results in differences in educational situations. The purpose of this study was to investigate desirable neuroanatomy education methods for large and small numbers of students. The situations of neuroanatomy education in China and Korea were compared systematically. With a questionnaire survey, positive comments and recommendations for their counterparts were collected from the medical students (168 Chinese and 41 Koreans) and anatomists (6 Chinese and 3 Koreans). By reviewing the opinions, the Chinese and Korean anatomists could learn from each other to improve their strong points and make up for the weak points. The results also disclosed the common problems of neuroanatomy education, which could be relieved by developing the fitting book and the self-learning tools, such as lecture videos and stereoscopic computer models.

Esta considerable variable del número de estudiantes resulta en diferencias en las situaciones educativas. El propósito de este estudio fue investigar métodos de educación en neuroanatomía deseables para cantidades mayores y menores de estudiantes. Se compararon sistemáticamente las situaciones de educación en neuroanatomía en China y Corea. Por medio de una encuesta por cuestionario, se obtuvieron comentarios positivos y recomendaciones para sus contrapartes de los estudiantes de medicina (168 chinos y 41 coreanos) y anatomistas (6 chinos y 3 coreanos). Al revisar las opiniones, los anatomistas chinos y coreanos podrían aprender unos de otros para mejorar sus puntos de fortaleza y compensar los aspectos débiles. Los resultados también revelaron los problemas comunes de la educación en neuroanatomía, que podrían aliviarse desarrollando el libro de adaptación y las herramientas de autoaprendizaje, como videos de conferencias y modelos de computadora estereoscópica.

Willingness toward organ and body donation among anatomy professors and students in Mexico.

Most anatomists agree that cadaver dissection serves as a superior teaching tool in human anatomy education. However, attitudes toward body donation vary widely between different individuals. A questionnaire was developed to determine the attitudes toward body and organ donation among those who learn the most from cadavers: medical students, medical student teaching assistants, medical students involved in research, and anatomy professors. A cross-sectional, prospective study was designed in which the questionnaire was distributed among first-year human anatomy students before undertaking cadaver dissection at the beginning of the semester, and then again after a commemoration service at the end of the course. The questionnaire items included demographic data, as well as questions designed to characterize participants' attitudes regarding body/organ donation from strangers, family members, and whether participants would consider such practices with their own bodies. Out of a total of 517 students enrolled in the Human Anatomy course in the Medical School at the Universidad Autónoma de Nuevo León, Mexico during January to June 2016, 95% responded to the first (491) and second (490) surveys. Participants' opinions on their own organ donation was similar before and after exposure to cadaver dissection, with between 87% and 81% in favor of such practices, and only 3% against it, in both surveys. Participants' willingness to donate their own bodies, as well as those of family members, increased, while reluctance regarding such practices decreased by half (P < 0.0001 and P < 0.05). Professors had the highest rates of positive opinions regarding their own body donation (74.9%), with 18.8% undecided. Low opposition toward organ and body donation remains prevalent among both anatomists and physicians in training in Mexico. Anat Sci Educ 10: 589-597. © 2017 American Association of Anatomists.

Leonardo da Vinci (1452-1519) and his depictions of the human spine.

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

Evolução cronológica do conhecimento neuroanatômico / Chronological evolution of neuroanatomical knowledge

Desde a antiguidade, o pensamento científico evoluiu em fases e este artigo faz uma análise histórica sucinta sobre o avanço do conhecimento neuroanatômico. Assim, foi feita uma análise temporal que não somente permite uma descrição dessa evolução, bem como esclarece o modo e a profundidade com que as estruturas foram sendo compreendidas. A descrição das descobertas neuroanatômicas subdividida em quatro fases temporais distintas permitiu compreender a evolução do pensamento neurológico e as correlações existentes entre os relatos.

Since ancient times, the scientific thinking evolved in stages, and thisarticle is a brief historical analysis of the progress of the neuroanatomical knowledge. Consequently, a temporal analysis not only provides a description of this evolution, as explained by the manner and depth with which the structures were being understood. The description of the neuroanatomical finfings subdivided into four distinct temporal phases allowed to understand the evolution of neurological thought and the correlations between the reports.

[Manuel Julián Grajales: propagator of smallpox vaccine in South America. Anatomist and surgeon]. / Manuel Julián Grajales: Propagador de la vacuna antivariólica en América del Sur. Anatomista y cirujano.

Grajales came to Chile in December 1807, noting that since 1805 smallpox vaccination had been introduced by Fray Pedro Manuel Chaparro, supported by the Councilor Nicholas Matorras. He founded the Vaccination Boards of Valparaiso and Santiago in 1808 and became professor of anatomy and surgery in 1819. In 1823 he received his authorization to practice medicine. He wanted to finish his medical studies at the University of San Marcos in Lima, but the war of Independence made this impossible. He returned to Spain in 1825. In 1848, he became Member of Honor of the Faculty of Medicine, Universidad de Chile.

Contribuciones de Wilhelm his a la embriología humana / Contributions of Wilhelm his to human embryology

Wilhelm His (1831-1904) gran anatomista y embriólogo suizo, profesor de la cátedra de anatomía de la Universidad de Basilea y Universidad de Leipzig. His, realizó el primer intento de estudiar los distintos estadios del embrión humano en su totalidad. Para tal fin, introdujo importantes avances tecnológicos que permitieron una comprensión más detallada del embrión humano, marcando un hito en el desarrollo de la embriología como ciencia. En este trabajo se resumen las principales contribuciones de Wilhelm His en el campo de la embriología humana. Uno de sus principales aportes fue la invención del micrótomo en 1866, el cual permitió reconstruir el embrión a partir de secciones histológicas. Otro de sus grandes inventos fue el denominado embriógrafo, instrumento que posibilitó la visualización de cortes histológicos en bajos aumentos y su reconstrucción sobre un papel. Además, fue pionero en intentar seleccionar los embriones humanos colectados presumiblemente en orden de su desarrollo. Dividió el desarrollo humano en estadios, estableciendo normas a partir de las relaciones entre forma y tamaño característicos de cada estadio. Gran parte de sus descubrimientos sobre el desarrollo del embrión humano se encuentran plasmados en el trabajo titulado Anatomie der Menschlichen Embryonen (1880-1885). La noble tarea de dilucidar la anatomía del embrión humano fue posible gracias este conjunto de innovaciones tecnológicas y metodológicas y su perseverante trabajo. Debido a sus grandes aportes en el campo de la embriología se le confiere el nombre de "Vesalius de la embriología humana".

Wilhelm His (1831-1904), a great Swiss anatomist and embryologist, professor of anatomy at the university of Basel and the university of Leipzig. His, made the first attempt to study the different stages of the total human embryo. For that purpose he introduced important technological advances that allowed a more detailed understanding of the embryo, setting a landmark in the development of embryology as a science. This paper summarizes the main contributions of Wilhelm His in the field of human embryology. One of his major contributions was the invention of the microtome en 1866, which allowed the reconstruction of the embryo from histological sections. Another one of his great inventions was the so-called embryograph, an instrument that allows viewing histological sections at low magnification and reconstructing them on paper. He was also a pioneer in attempting to select human embryos presumably collected in their order of development. He divided human development into stages, establishing standards from the relations between the shape and size characteristic of each stage. A large part of his discoveries on the development of the human embryo is found in his work titled Anatomie der Menschlichen Embryonen (1880-1885). The noble task of elucidating the anatomy of the human embryo was possible thanks to a set of technologicals and methodological innovations and his persevering work. Because of his great contributions in the field of embryology he is given the name of "Vesalius of human embryology".

CONCLUSIONS: The present historic paper reviews the life and contributions of Robert Liston and discusses his fascination with childhood hydrocephalus.

Marcello Malpighi (1628-1694), Founder of Microanatomy / Marcello Malpighi (1628-1694), Fundador de la Microanatomía

Marcello Malpighi, (1628-1694), Italian physician, anatomist, botanist, histologist and biologist developed methods to study living things by using the newly invented microscope to make a number of important discoveries about living tissue and structures, and initiated the science of microscopic anatomy. For almost 40 years he used the microscope to describe major types of plant and animal structures and, in doing so, discovered major areas of research in botany, embryology, human anatomy and pathology for future generations of biologists. He provided anatomical basis for eventual understanding of human physiological exchanges. Marcello Malpighi was the founder of microanatomy. Many microscopic anatomical structures are named after him: the basal layer, renal corpuscles, as well as insect excretory organs.

Marcelo Malpighi, (1628-1694), médico italiano, anatomista, botánico, histólogo y biólogo, usando el microscopio, recientemente inventado en esa época, desarrolló métodos para estudiar organismos vivos, con lo cual contribuyo al inicio del desarrollo de la ciencia de la anatomía microscópica. Por casi 40 años Malpighi utilizó el microscopio para describir los tipos principales de estructuras de algunas plantas y animales, facilitando el inicio de campos de investigación importantes en botánica, embriología, anatomía humana y patología. Marcelo Malpighi fue fundador de la anatomía microscópica. Muchas estructuras anatómicas microscópicas se nombran en su honor, como; la capa de Malpighi, los corpúsculos renales, así como los túbulos renales.
