Sternal part of diaphragm
Pars sternalis diaphragmatis
Definition
The sternal part of the diaphragm is one of the three main segments of the diaphragm, the other two being the costal and lumbar parts. The sternal part originates from the posterior surface of the xiphoid process of the sternum by two fleshy slips. It consists of muscle fibers that extend posteriorly and laterally to insert into the central tendon of the diaphragm.
