Episternum, ep-i-ster′num, n. the interclavicle: the epiplastron: the presternum of mammals.
The presternum has a prominent keel for the attachment of the pectoral muscles.
In the Chiroptera the presternum is strongly keeled and so is sometimes the mesosternum.
The two clavicles are joined across the top of the presternum by an interclavicular ligament.
