Cultural changes, scientific progress, and new trends in medical education have modified the role of dissection in the teaching of anatomy in today’s medical schools. Dissection is indispensable for a correct and complete knowledge of human anatomy, which can ensure safe as well as efficient clinical practice and the hu- man dissection lab could possibly be the ideal place to cultivate humanistic qualities among future physicians. In this manuscript, we discuss the role of dissection itself, the value of which has been under debate for the last 30 years; furthermore, we attempt to focus on the way in which anatomy knowledge was delivered throughout the centuries, from the ancient times, through the Middles Ages to the present. Finally, we document the rise of plastination as a new trend in anatomy education both in medical and non-medical practice.

A Brief History of the Practice of Anatomical Dissection
Open Access Rambam Maimonides Medical Journal HISTORY OF MEDICINE Post-Mortem Pedagogy: A Brief History of the Practice of Anatomical Dissection Connor T. A. Brenna, B.Sc., M.D.(C.)* Department of Medicine, University of Toronto, Toronto, ON, Canada ABSTRACT Anatomical dissection is almost ubiquitous in modern medical education, masking a complex history of its practice. Dissection with the express purpose of understanding human anatomy began more than two millennia ago with Herophilus, but was soon after disavowed in the third century BCE. Historical evidence suggests that this position was based on common beliefs that the body must remain whole after death in order to access the afterlife. Anatomical dissection did not resume for almost 1500 years, and in the interim anatomical knowledge was dominated by (often flawed) reports generated through the comparative dissection of animals. When a growing recognition of the utility of anatomical knowledge in clinical medicine ushered human dissection back into vogue, it recommenced in a limited setting almost exclusively allowing for dissection of the bodies of convicted criminals. Ultimately, the ethical problems that this fostered, as well as the increasing demand from medical education for greater volumes of human dissection, shaped new considerations of the body after death. Presently, body bequeathal programs are a popular way in which individuals offer their bodies to medical education after death, suggesting that the once widespread views of dissection as punishment have largely dissipated.

He devoted all his life to his studies in medicine and anatomy. He began his research work with explaining the compilations of othe- physicians then turned his way, and began writing his own books based on his pe-sonal experiments on human bodies and animals, and could come to his own conclu- sions about the mechanism of action of the different organs. He also tried his best to present medicine to the common people as simple as possible. He described many forms of dietary food, best drugs to use etc. He gave specified new nomenclature and defini- tions to drugs also. Thus his life was filled with scientific activity specially medicine arid helped in directing it to the right and true path which guided the European scientists to follow his ideas and to discover more about it.

02C Fetal Pig Autopsy
Name(s): ________________________ HASPI Medical Anatomy & Physiology 02c Lab Activity Period: _________ Date: ___________ The following outlines the standard procedure and protocol for an autopsy performed by a medical examiner or coroner. Step 1. Preliminary Procedures Details are crucial to an autopsy! Anyone who will be reading the autopsy report will need to be able to follow these details step-by-step. This starts with identification of the victim (if known), case number, as well as the location, date, time, and reason for the autopsy. Any other special considerations also need to be recorded. Step 2. Summary of Known Circumstances http://www.pathguy.com/lectures/autopsy_6_11_07_1.jpg This is a short summary of the known facts about the victim. This most often includes the victim’s sex, race, and age. If known, it will also include a description of the circumstances in which the body was found. Any additional information on the victim’s plans or activities before or after death will also be included. Step 3. Review Documents and Examine Evidence Any reports created during the police investigation should be reviewed before autopsy. This allows for the medical examiner to have an idea of what he or she may be looking to find. In some cases, the type and shape of a weapon are crucial details in determining if any of the injuries found on the victim may be connected to any weapons found at the scene. Step 4. External Examination of the Body It is important to note any and all external details before disturbing the victim. Simple notes like the condition, state, or position of an item of clothing may be the detail needed by investigators to piece together a crime scene.

Pathology Bibliography Biographical Sketch Summary A short account is given of the development of biological sciences from their Greek origins to recent times. Biology as a pure science was the creation of Aristotle, but was abandoned shortly after his death. However, considerable advances relevant for medicine continued to be made until the end of classical times, in such fields as anatomy and botany. These developments are reviewed. After a long pause, both pure and applied research began anew in the thirteenth century, and developedUNESCO at an increasing pace therea fter.– However, EOLSS unlike astronomy and physics, which experienced a startling resurgence as soon as adequate mathematical methods and instruments became available, the development of biology was steady but slow until the appearance of Darwin’s revolutionary ideas about evolution brought about a fundamental shiftSAMPLE in the subject’s outlook. TheCHAPTERS efflorescence of biological sciences in the post-Darwinian period is outlined briefly. 1. Introduction To outline more than 2000 years of biology in a few pages is an extremely difficult endeavor as, quite apart from the complexities of both the subject itself and of the technical and theoretical approaches of various scholars, the development of scholars’ views, ideas, and researches forms an intricate network that cannot be fully disentangled in such a brief account.

Clinical and Pathologic Findings of Aortic Dissection at Autopsy: Review
Clinical Investigation Clinical and pathologic findings of aortic dissection at autopsy: Review of 336 cases over nearly 6 decades Nick Huynh, MD, a Sarah Thordsen, MD, a Taylor Thomas, a Shannon M. Mackey-Bojack, MD, b Emily R. Duncanson, MD, b Darlington Nwuado, a Ross F Garberich, MS, a and Kevin M. Harris, MD a Minneapolis and St Paul, MN Abstract Background We aimed to characterize the clinical and pathologic findings of aortic dissection (AD) over a nearly 60-year period. Methods The Jesse E. Edwards Registry of Cardiovascular Disease database was queried for cardiac specimens from autopsies with AD as a diagnosis and compared 2 cohorts: early (1956-1992) and current (1993-2015). Results From 1956 to 2015, 338 cases (166 early, 170 current) with AD were included (mean age: 60; 62% male). The AD was 86% type A and 14% type B. Sixty-two percent of cases were under medical care at time of death (61% early, 62% current, P = not significant). Of those under medical care, 63% were not diagnosed prior to death (64% early, 62% current, P = not significant). Risks for dissection did not differ between time intervals and include left ventricular hypertrophy, suggestive of hypertension (84%), prior cardiovascular surgery (38%), bicuspid valve (14%), and connective tissue disease (9%). An intimal tear was identified in the ascending aorta in the majority (68%), followed by descending (14%), root (9.5%), and arch (7%). Aortic rupture occurred in 58%, most frequently in the ascending aorta (41%). Conclusions In a large cardiovascular registry, N60% of cases of AD were not detected clinically and first identified at autopsy.

The rise of European science during the Renaissance is greatly indebted to the ﬂourishing of the sciences during the Islamic Golden Age. However, some believe that medieval Islamic physicians and in particular surgeons had been merely a medium for Greco-Roman ideas. Contrarily, in some medieval Islamic medical books, such as Al-Tasrif of Al-Zahrawi (936–1013), the surgical instructions represent a change in the usual techniques or are accompanied by a case history, implying that the procedure was actually undertaken.
