What is the name of the inferior tip of the sternum?

The inferior tip of the sternum is known as the xiphoid process. This structure is a small, cartilaginous extension located at the lower end of the sternum, which typically ossifies into bone as an individual ages. It serves as an important landmark for various medical procedures and examinations, such as cardiopulmonary resuscitation (CPR), where proper positioning of hand placement is critical to effective chest compressions.

In contrast, the manubrium refers to the upper portion of the sternum and is not the tip. The sternal notch is the concave area on the superior border of the manubrium, and the body of the sternum constitutes the middle portion, which connects the manubrium above and the xiphoid process below. Understanding the anatomy of the sternum, including the xiphoid process, is essential for recognizing its role in the structure of the thoracic cavity and the protection of internal organs.
