The Sternum Bone Parts: Structure, Functions, and Benefits Explained

The sternum, commonly known as the breastbone, is a flat bone that forms the front portion of the rib cage. It consists of three main parts: the manubrium, the body, and the xiphoid process. The manubrium connects to the clavicles and the first two pairs of ribs, while the body joins the remaining ribs, and the xiphoid process is a small, cartilaginous extension at the lower end. The sternum's primary functions include protecting vital organs such as the heart and lungs by providing a rigid framework for the rib cage and serving as an attachment site for the costal cartilages and muscles. Technological features of the sternum involve its unique structure that allows for the absorption and distribution of forces, contributing to the structural integrity of the thoracic cavity. In medical and forensic applications, understanding the sternum's structure is crucial for identifying individuals and studying patterns of bone development and pathology.
