Masseter action

MASSETER. ORIGIN Anterior two thirds of zygomatic arch and zygomatic process of maxilla: INSERTION Lateral surface of angle and lower ramus of mandible: ACTION Masseter function The Masseter muscle elevates of mandible as in closing the mouth. Its insertion along the angle and lateral surface of the ramus also allows it to aid in the protrusion of the mandible allowing for the anterior motion of the jaw. The masseter muscle is one of the four muscles responsible for the action of mastication (chewing). The primary action of the muscle is to elevate the mandible and close the jaw. The deep fibers of the muscle also retrude the mandible.

Its insertion along the angle and lateral surface of the ramus also allows it to aid in the protrusion of the mandible allowing for the anterior motion of the jaw.

The routine neurological examination includes testing of the jaw jerk reflex, also known as the masseter or mandibular reflex. The examiner places his index finger on the chin of the patient and taps the finger with the reflex hammer. In healthy people, the stretch of the masseter provokes an upward movement of the mandible.
