Dissection
Dissection (from Latin dissecare ""to cut to pieces""; also called anatomization, from Greek anatomia, from ana- ""up"" and temnein ""to cut"") is the process of disassembling and observing something to determine its internal structure and as an aid to discerning the functions and relationships of its components. The term is most often used concerning the dissection of plants and animals, including humans. Human dissection is commonly practiced in the teaching of anatomy for students of medicine, while students of biology often engage in dissections of animals, but also of plants. Dissection is a medical practice utilized in pathology and forensic medicine during autopsy. Vivisection is related to dissection, but is done on living specimens.
