masticatory muscles

[TA]
muscles derived from the first (mandibular) arch used in chewing; all receive innervation from the motor root of the trigeminal nerve via its mandibular division; includes masseter muscle, temporalis muscle, lateral pterygoid muscle, and medial pterygoid muscle.
Synonym(s): musculus masticatorii [TA], muscles of mastication, musculi masticatorii

muscles of mastication

a group of muscles-the masseter, pterygoideus lateralis, pterygoideus medialis, and temporalis-responsible for movement of the jaws during the process of chewing. All four muscles are innervated by the mandibular division of the trigeminal nerve.
