Which bone contains the manubrium, body, and xiphoid process?

The bone that contains the manubrium, body, and xiphoid process is the sternum. This flat bone is located in the center of the chest and serves as a crucial part of the rib cage, protecting vital organs such as the heart and lungs.

The manubrium is the upper portion of the sternum, connecting with the clavicles and the first pair of ribs. Below it is the body of the sternum, which is the longest segment and connects to the ribs through costal cartilage, aiding in the stability of the rib cage. Finally, the xiphoid process is the smallest, most inferior portion of the sternum, which can serve as a landmark for certain medical procedures and is the attachment point for several muscles. Each of these components plays an essential role in the structure and function of the thoracic skeleton, which is vital for both respiration and protection of thoracic organs.
