SternumDefinition (http://en.wikipedia.org/wiki/Sternum) The sternum or breastbone, in vertebrate anatomy, is a flat bone that lies in in the middle front part of the rib cage. It probably first evolved in early tetrapods as an extension of the pectoral girdle; it is not found in fish. In amphibians and reptiles it is typically a shield-shaped structure, often composed entirely of cartilage.
