![]() ![]() Galen (129–c.200 AD), Opera omnia, dissection of a pig. If pathological connections exist, such as a fibrous pericardium, then this may be deliberately dissected along with the organ. For example, when removing the heart, connects such as the superior vena cava and inferior vena cava are separated. Dissection of individual organs involves accessing the area in which the organ is situated, and systematically removing the anatomical connections of that organ to its surroundings. The Rokitansky method involves an in situ dissection of the organ block, and the technique of Ghon involves dissection of three separate blocks of organs - the thorax and cervical areas, gastrointestinal and abdominal organs, and urogenital organs. This technique allows a body to be sent to a funeral director without waiting for the sometimes time-consuming dissection of individual organs. An alternative more cumbersome technique involves the removal of the entire organ body, called the Letulle technique. Most dissection involves the careful isolation and removal of individual organs, called the Virchow technique. This preparation is sometimes called prosection. A "prepared" specimen may be preserved in solutions such as formalin and pre-dissected by an experienced anatomist, sometimes with the help of a diener. A "fresh" specimen may be dissected within some days, retaining the characteristics of a living specimen, for the purposes of training. When provided, they are evaluated for use as a "fresh" or "prepared" specimen. Specimens are dissected in morgues or anatomy labs. Prevention of transmission includes the wearing of protective gear, ensuring the environment is clean, dissection technique and pre-dissection tests to specimens for the presence of HIV and hepatitis viruses. Ī key principle in the dissection of human cadavers is the prevention of human disease to the dissector. ĭissection is used to help to determine the cause of death in autopsy (called necropsy in other animals) and is an intrinsic part of forensic medicine. In medical schools, students dissect human cadavers to learn anatomy. Dissection is practised by students in courses of biology, botany, zoology, and veterinary science, and sometimes in arts studies. Access to the entire database requires a licence, but some online samples are available.Plant and animal bodies are dissected to analyze the structure and function of its components. The result is a virtual male and female data set built from actual CT, MRI and cryosection scans. Pupils have 12 autopsies to perform, and are asked to determine the cause of death in each case.Īt the high end of these online offerings is the Visible Human Project at the National Library of Medicine ( Developers here have been building a complete digital database of human anatomy since 1989. The Virtual Autopsy at Leicester University ( /pathology/teach/va/) is aimed at the pre-clinical medical student. Of course, the ultimate training ground for medical students is the human body, and the Internet serves up a wealth of virtual cadavers. us /fkchs/vpig/) students can cut into an electronic hog. html), while over at the Virtual Pig Dissection site ( 27. The Berkeley High School offers whole-cat dissection ( /de part ments/Scien ce /anatomy /cat /index. Students can also tackle the wonders of a cow's eye ( or delve into the marvels of a sheep's brain at the University of Scranton ( academic. It challenges users to reconstruct a frog from the nerves up - a twist on the normal dissection process.īut frogs are only one of the virtual creatures available for bloodless dissection. Staying with frogs, the Lawrence Berkeley National Laboratory has created The Virtual Frog Dissection Kit ( Students can interactively dissect a digital frog named Fluffy, create movies and play the Virtual Frog Builder Game. There are also some interactive sessions that ask the student to choose the right incision points. Launched 7 years ago, it is aimed at high school level students and offers photos, illustrations and short videos of actual frog dissections. ![]() One of the first sites developed was The Interactive Frog Dissection ( /go/frog/). It now offers a “virtual” way to slice and dice everything from your favourite amphibian to the human body. Starting with the lowly frog, students learn the basics of anatomy by practising on the real thing. The art and science of the scalpel is learned through long hours of study and hands-on dissection. ![]()
