Masseter muscle
 

 

In human anatomy, the masseter is one of the muscles of mastication. It originates from the zygomatic arch and inserts into the mandible. Its action is to close the jaw. It is innervated by the mandibular branch of the trigeminal nerve (V3). It is particurlaly powerful in herbivores to assist when they are chewing plants.
