The Jaw

Temporalis ("temp-or-RAL-iss") fills out the area of the temple and the side of the head between the cranium and the zygomatic bone, which it ducks under to attach to the mandible. Masseter ("MASS-eh-ter") originates on the zygomatic arch and attaches to a wide area near the angle of the mandible. Both of these muscles close the jaw, and can be seen as wide bulges when tensed.
