Identify the parts of the sternum: The manubrium is the upper part of the sternum, the body is the central and largest part, and the xiphoid process is the small, cartilaginous section at the lower end.
Recognize the function of the sternum: The sternum serves as an attachment point for several ribs and helps protect vital organs such as the heart and lungs.
Differentiate between the sternum and other bones: The clavicle, also known as the collarbone, is not part of the sternum. It is a separate bone that connects the sternum to the scapula (shoulder blade).
