The muscles of mastication that close the jaws are the temporal, masseter, and medial and lateral pterygoid muscles, all of which are innervated by the mandibular nerve (the only motor branch of the trigeminal nerve). The digastricus muscle opens the mouth. Its rostral belly is innervated by the mandibular branch of the trigeminal nerve, while its caudal belly is innervated by the facial nerve. The body (the rostral two‐thirds) of the tongue is attached ventrally to the midline of the floor of the mouth by the lingual frenulum.
