Dissection (from Latin dissecare "to cut to pieces"; also called anatomization, from Greek anatomia, from ana- "up" and temnein "to cut"), is the dismembering of the body of an animal or plant to study its anatomical structure. Autopsy is used in pathology and forensic medicine to determine the cause of death in humans. It is carried out by or demonstrated to biology and anatomy students in high school and medical school. Less advanced courses typically focus on smaller subjects, such as small formaldehyde-preserved animals, while the more advanced courses normally use cadavers.
