It is regularly observed in lower animal but infrequently in humans. Presence of this muscle can create confusion with tumours of the anterior chest wall during routine mammography. Although less is known about its origin and innerva...

The sternalis muscle is a derivative of superficial part of the rectus abdominis ...
