Sternum

The sternum or breastbone is a long flat bony plate shaped like a capital “T” located anteriorly to the heart in the center of the thorax (chest). It connects the rib bones via cartilage, forming the anterior section of the rib cage with them, and thus helps to protect the lungs, heart and major blood vessels from physical trauma. Although it is fused, the sternum can be sub-divided into three regions: the manubrium, the body, and the xiphoid process.
