Facial muscles

What movements or gestures can humans make with their faces? Some "facial" gestures actually are head movements, such as nodding or shaking the head, or turning away in disgust.

This module will ignore those head gestures and concentrate on the more subtle movements of the facial muscles that affect the position of the eyebrows and eyelids, the shape of the mouth, and the appearance of the wrinkles around the mouth, eyes, and nose.
