The sternum, commonly known as the breastbone, is a long, narrow flat bone that serves as the keystone of the rib cage and stabilizes the thoracic skeleton. Several muscles that move the arms, head, and neck have their origins on the sternum.
The Sternum. The sternum is the flat bone located in the middle of the chest. The sternum, together with the ribs, forms the ribcage that helps to protect the heart and the lungs, as well as major blood vessels. Ribs are connected to the sternum by cartilage. The sternum is composed of the following three parts: the manubrim, the gladiolus and the xiphoid process. In adults, the three parts of the sternum are often bone that is fused together. The manubrim is located at the top of the sternum.
