Anatomical terms of muscle

Sternalis is a muscle that lies in front of the sternal end of the Pectoralis major parallel to the margin of the sternum. It is supplied by the anterior thoracic nerves[disambiguation needed] and is probably a misplaced part of the pectoralis.

Sternalis is a muscle that runs along the anterior aspect of the body of the sternum. There are two different theories as to what the Sternalis was meant to be connected to. One is the Pectoralis major, the other is the rectus abdominus, as in several cases the sternalis was actually found to have interlaced fibers with the rectus abdominis, but be enervated by the same nerve pathways as the pectoralis major.
