<span>Studying the gross anatomy of a cadaver can show an individual the total physiology of a human. By dissecting a cadaver or deceased human, you can study the nervous and cardiovascular system as well as the organs and other internal tissues. For example, muscle origin and insertions on bone, blood supply to the muscle and nervous stimulation of the muscle can be studied. Other areas that can be seen are the location of major organs in the thorax and the blood supply to each of them. The discovery of how the cadaver died can also bee seen during the dissection in many cases.</span>
