sternum

the breastbone, a median segmented skeletal structure made up of several elements or sternebrae, often with a considerable portion remaining cartilaginous into adulthood. It articulates with the cartilages of the sternal ribs and clavicles when large. It has three parts, the manubrium, the body and the xiphoid process, and consists of vascular, spongy bone covered with a thin layer of compact bone. In ruminants it has a flat ventral surface, while in horses it bears a keel (carina). It is especially well developed, as a nonsegmented keeled bone, in flying birds.
