The muscles of facial expression are innervated by the facial nerve (cranial nerve VII). This nerve originates in the brainstem and branches out to supply the muscles involved in facial expressions, such as the orbicularis oculi, zygomaticus, and frontalis muscles. Damage to the facial nerve can result in facial muscle weakness or paralysis on the affected side of the face.

The muscle that resides in the cheek is names the buccinator and is innervated by the facial nerve. It is primarily a muscle of facial expression. Its function in mastication (chewing) is to push the food, with the aid of the tongue, to the opposite side of the mouth. It is, however, only able to form part of the inward movement of the cheeks; the rest is caused by negative pressure (semi-vacuum) being created by the action of the inferior tongue muscles pulling the tongue down and back.
