Definition[Bearbeiten]
The xiphoid process is the smallest, lower part of the breastbone (sternum).
Anatomy[Bearbeiten]
The xiphoid process occurs in relatively many different forms. It is connected to the body of the sternum (corpus sterni) via a synchondrosis or synostosis. The ligamenta costoxiphoidea run between the xiphoid and the ribs, which are not directly connected to the xiphoid.
The lower end and the front surface of the xiphoid process serve as an attachment for the linea alba and part of the rectus abdominis muscle. The lateral surfaces and the posterior surface serve as an attachment for individual fibre tracts of the aponeuroses of the lateral abdominal muscles and the diaphragm.
