Xiphoid process
（重定向自Xyphoid）
The xiphoid process /ˈzaɪfɔɪd/, or xiphisternum or metasternum, is a small cartilaginous process (extension) of the lower part of the sternum which is usually ossified in the adult human. It may also be referred to as the ensiform process. Both the Greek derived xiphoid and its Latin equivalent ensiform mean 'sword like'.
