What is the breast bone called?

Explanation:
The breast bone is the sternum, a flat, elongated bone along the midline of the chest that forms the front part of the rib cage. It protects the heart and lungs and provides attachment for the ribs via costal cartilages as well as for the clavicles at the sternoclavicular joints. The sternum has three parts—the manubrium, the body, and the xiphoid process—which together anchor the rib cage and contribute to its flexibility and stability. The other bones listed have different roles: the clavicle is the collarbone, the scapula is the shoulder blade, and the ribs are the curved bones that form the cage but are not called the breast bone.
