Peer Review Status: Internally Peer Reviewed


This muscle is frequently absent or may be represented by some scattered muscular bands. Its intimate association with depressor anguli oris suggests derivation from that muscle. The muscle varies in the extent of its distribution and has been found arising from the fascia over the sterno- mastoid, muscle, or the mastoid process, the outer ear or zygomatic process. It has been found doubled and tripled.
