Sternum

The sternum, often referred to as the breastbone, is a long, flat bone located in the center of the rib cage. It serves as a crucial point of attachment for the ribs, providing protection to the vital organs within the chest, including the heart and lungs. It's composed of three main parts: the manubrium (superior), the body (middle), and the xiphoid process (inferior). The sternum also contributes to the structural support of the upper body and plays a role in the mechanics of breathing by expanding and contracting during respiration. The sternum is a relatively thick bone and is comprised of both spongy and cortical bone.
