Facial Expressions

A facial expression is one or more motions or positions of the muscles beneath the skin of the face. According to one set of controversial theories, these movements convey the emotional state of an individual to observers. Facial expressions are a form of nonverbal communication.
Facial expressions are an important part of body language. We use our faces to express ourselves, and we all interpret the facial expressions we see. While some facial expressions are cultural, some facial expressions are universal.
