The xiphoid process (/ ˈzɪfɔɪd /), also referred to as the ensiform process, xiphisternum, or metasternum, constitutes a small cartilaginous process (extension) located in the inferior segment of the sternum, typically ossified in adult humans. [1] Both the Greek-derived term xiphoid and its Latin equivalent, ensiform, connote a "swordlike ...
The sternum (pl.: sternums or sterna) or breastbone is a long flat bone located in the central part of the chest.It connects to the ribs via cartilage and forms the front of the rib cage, thus helping to protect the heart, lungs, and major blood vessels from injury.

It is structurally classified as a synchondrosis, and functionally classified as a synarthrosis. [citation needed] The joint usually ossifies by the fourth ...
The costal margin is the medial margin formed by the cartilages of the seventh to tenth ribs. It attaches to the body and xiphoid process of the sternum.
