Embryology
For example, muscles that arise from the mandibular arch (i.e., the temporal, masseter, pterygoid, and mylohyoid muscles and the tensor of the tympanum, tensor of the velum palatinum, and the anterior belly of the digastric muscles) are supplied by the trigeminal nerve, the nerve of the mandibular arch.
