What is the lower tip of the sternum called?

• A. Xiphoid process
• B. Manubrium
• C. Body of sternum
• D. Sternal notch

Answer: (A)

The lower tip of the sternum is called the xiphoid process. This small, cartilaginous structure typically begins as cartilage during infancy and gradually ossifies into bone as a person matures. Its location at the inferior end of the sternum makes it important for anatomical landmarks, especially in procedures like cardiopulmonary resuscitation (CPR) or in identifying correct hand placement during chest compressions. In contrast, the manubrium is the broad, upper part of the sternum where the clavicles articulate. The body of the sternum refers to the central portion, which connects to the manubrium above and the xiphoid process below. The sternal notch is a small indentation at the superior aspect of the manubrium, not related to the lower tip of the sternum. Understanding the correct terminology and location of these structures is essential for effective communication in medical settings and for performing certain medical procedures accurately.
