Facial muscles

The facial muscles (also called the muscles of facial expression) are situated within the subcutaneous tissue of the face. They are responsible for the movements of skin folds, providing different facial expressions. The facial muscles originate from the bones of the facial skeleton (viscerocranium) and insert into the skin. 

These muscles are mostly grouped around the natural orifices of the face (eyes, nose, and mouth), taking part in the closing or widening of these orifices. 

All muscles of facial expression are innervated by branches of the facial nerve (CN VII).
