The masseter. It can exert an amazing force. I think it was 700 pounds of pressure.
The muscle that aids the jaw in closing is the temporalis muscle. The masseter is the muscle that primarily moves the jaw.
Mastication, or chewing, involves a total of four muscles. These muscles are the masseter, temporalis, medial pterygoid, and lateral pterygoid.
The masseter muscle is the major jaw muscle, and is able to generate more force than any other muscle in the body.
