Is the xiphoid process located inferior to the manubrium?

The xiphoid process is indeed located inferior to the manubrium. The manubrium is the upper part of the sternum, and it articulates with the clavicles and the first two pairs of ribs. It serves as a superior landmark on the sternum, while the xiphoid process, which is a small, cartilaginous structure, is positioned at the lower end of the sternum. As the sternum is a vertical structure, with the manubrium at the top, the xiphoid process is directly beneath it, making it structurally and anatomically correct to say that the xiphoid process is located inferior to the manubrium.
