The facial muscles involved in chewing are: Buccinator, a thin muscle in your cheek that holds each cheek toward your teeth. Lateral pterygoid, a fan-shaped muscle that helps your jaw open. Masseter, a muscle that runs from each cheek to each side of your jaw and helps your jaw close.
Lateral Superficial Facial Muscles
The facial muscles are just under the skin ( subcutaneous) muscles that control facial expression. They generally originate from the surface of the skull bone (rarely the fascia), and insert on the skin of the face. When they contract, the skin moves. These muscles also cause wrinkles at right angles to the muscles' action line.
