The following facial muscles are innervated by cranial nerve VII (facial nerve):
- orbicularis oris (closes lips)
- caninus (snarling in a dog)
- levator nasolabialis (lifts nose and upper lip)
- levator labii superioris (lifts upper lip)
- depressor labii inferioris (depresses lower lip)
- caudal belly of the digastricus (opens jaw)
Levator palpebrae superioris which is innervated by the oculomotor nerve. This muscle elevates the upper eyelids and opens the eye.
Most are innervated by CN 7 (facial nerve). IF you include eye movements, you must add CN's III (oculomotor) IV (Trochlear) and VI (abducens)
Posterior Belly of Digastric Muscle (innervated by CN VII) Facial nerve Sternocleidomastoid (innervated by CN XI) Spinal accessory nerve Longissimus Capitis (innervated by dorsal rami of C3-C8 spinal nerves) Splenius Capitis (innervated by dorsal rami of middle cervical spinal nerves)
Levator labii superioris
A caninus muscle is a a facial muscle of the mouth
The muscle that resides in the cheek is names the buccinator and is innervated by the facial nerve. It is primarily a muscle of facial expression. Its function in mastication (chewing) is to push the food, with the aid of the tongue, to the opposite side of the mouth. It is, however, only able to form part of the inward movement of the cheeks; the rest is caused by negative pressure (semi-vacuum) being created by the action of the inferior tongue muscles pulling the tongue down and back.
