After both of these men died the popularity of anatomical dissection decreased until it was not used at all. They practiced the dissection of cadavers in Alexandria, and it was the dominant means of learning anatomy. It all started in 3rd century ancient Greece with two physicians by the name of Herophilus of Chalcedon and Erasistratus of Ceos. The history of the use of cadavers is filled with controversy, scientific advancements, and new discoveries. The presence of carrion-consuming animals will also result in exposure of the skeleton as they consume parts of the decomposing body. The warmer and more humid the environment, the faster the body is broken down. The rate of decomposition depends on many factors including temperature and the environment. In acid-rich soils, the skeleton will eventually dissolve into its base chemicals. Eventually, sometimes after several years, all that remains is the skeleton. The muscles may be eaten by bacteria or devoured by animals. Under normal conditions, the organs are unidentifiable after three weeks. The digestive organs, brain, and lungs are the first to disintegrate. Putrefaction is where the larger structures of the body break down, and tissues liquefy. Gas accumulation and bloating will continue until the body is decomposed sufficiently for the gas to escape. This usually happens around the second week of decomposition. This bloating occurs largely in the abdomen, and sometimes in the mouth, tongue, and genitals. Bacteria in the gut begins to break down the tissues of the body, releasing gas that accumulates in the intestines, which becomes trapped because of the early collapse of the small intestine. The second stage of decomposition is bloating.

Hatched larvae ( maggots) of blowflies subsequently get under the skin and begin to consume the body. During this stage, flies (when present) begin to lay eggs in the openings of the body: eyes, nostrils, mouth, ears, open wounds, and other orifices. As a result of autolysis, liquid is created that seeps between the layers of skin and results in peeling of the skin. In other words, though autolysis resembles the active process of digestion of nutrients by live cells, the dead cells are not actively digesting themselves as is often claimed in popular literature and as the synonym of autolysis – self-digestion – seems to imply.
However, these enzymes are released into the cells because of cessation of the active processes in the cells, not as an active process. The first stage is autolysis, more commonly known as self-digestion, during which the body's cells are destroyed through the action of their own digestive enzymes.Observation of the various stages of decomposition can help determine how long a body has been dead. Cadaver in Refrigerator in the Forensic Medicine at the Charité Berlin Main article: Human decomposition Timeline of postmortem changes (stages of death). Ĭadavers have been used in art to depict the human body in paintings and drawings more accurately. Cadavers can be observed for their stages of decomposition, helping to determine how long a body has been dead. A cadaver graft (also called “postmortem graft”) is the grafting of tissue from a dead body onto a living human to repair a defect or disfigurement. Related terms include cadaverous (resembling a cadaver) and cadaveric spasm (a muscle spasm causing a dead body to twitch or jerk). The word comes from the Latin word cadere ("to fall"). The term cadaver is used in courts of law (and, to a lesser extent, also by media outlets such as newspapers) to refer to a dead body, as well as by recovery teams searching for bodies in natural disasters. In addition, a cadaver may be used in the development and evaluation of surgical instruments. Others who study cadavers include archaeologists and arts students. Students in medical school study and dissect cadavers as a part of their education. Cadavers are used by medical students, physicians and other scientists to study anatomy, identify disease sites, determine causes of death, and provide tissue to repair a defect in a living human being.
