Human Anatomy
Facemuscles of the eyelids
the sphincter muscle of the eyelids is the orbicularis oculi , and the dilator muscles are the levator palpebral superiors and the occipitofrontalis .muscles of the nostrils
the sphincter muscle is the compressor naris and the dilator muscle is the dilator narismuscles of the lips and cheeks
the sphincter muscle is the orbicularis oris . the dilator muscles consist of a series of small muscles that radiate out from the lips.sphincter muscle of the lips: orbicularis Oris
Nerve supply : Buccal and mandibular branches of facial nerve
Muscle of the cheek Buccinator
Nerve supply : Buccal branch of the facial nerve .
Sensory Nerves of the Face
The skin of the face is supplied by branches of the three divisions of the trigeminal nerve , except for the small area over the angle of the mandible and the parotid gland which is supplied by the greater auricular nerve (C2 and 3) . These nerves not only supply the skin of face , but also supply proprioceptive fibers to the underlying muscles of facial expression .They are , in addition ,the sensory nerve supply to the mouth , teeth , nasal cavities, and paranasal air sinuses
