Document Summary

Innervation: all of the facial muscles are innervated by the facial nerve (cranial nerve 10) Innervation: all of the muscles of mastication are innervated by the mandibular branch of the trigeminal nerve (cranial nerve 5) The medial and lateral pterygoid run underneath the masseter, you can not see it unless it gets moved. Innervation: hypoglossal nerve (cranial nerve 12) except the vagus nerve innervates the hyoglossus. You can only see these muscles if the mandible is cut: with the exception of the hyoglossus. Superior lateral surface of eye (tendon rests in a trochlea) The trochlea attaches to the superior rectus. Trochlea at the top, fatty part at the bottom orientate yourself. Flexes/rotates neck, assists in lifting ribs in respiration. Scaline muscles are innervated by the cervical root. Sternocleidomastoid is innervated by the accessory nerve (cranial nerve 11) Anterior belly = inner side of border of mandible, posterior belly = temporal bone. Rotation of head/neck, border for ant. /post/ neck muscles.
