The manubrium, body, and xiphoid process are the bones that make up what?
Explanation
Answer: A - The three sections that make up the sternum, or breastbone are (in order from superior to inferior): the manubrium, the sternum body, and the xiphoid process. The sternum is highly vascular and underlies the thymus gland. In the rib cage, it anchors the superior 7 ribs in the front and forms the anterior attachment for the clavicles. The sternal angle is formed where the manubrium superiorly joins the body of the sternum, also called the gladiolus, and is a useful landmark because the second ribs attach lateral to this angle.
