Face Anatomy and Physiology

Face Anatomy and Physiology:

There are about 30 muscles associated with facial expression (controlling the eyes, face and mouth).  These muscles take their origin form the bones of the facial skeleton and attach to the soft tissues of the facial skin, such as eyelids, nose, cheeks and lips.

The seventh (facial) cranial nerve  is the chief motor nerve of the face.  It emerges near the lower part of the ear.  It’s divisions and their branches supply and control all the muscle of facial expression, and extend to the muscles of the neck.  The buccal branch of the seventh cranial nerve affects the muscle of the mouth.
