The muscles of mastication control the jaw, specifically its adduction.
Your tongue assists with mastication. Mastication mainly is done by the Temporal Mandibular muscles though.

Trismus
muscle of mastication.
temporalis
The principal muscle of mastication that closes the mouth is the masseter muscle. This powerful muscle is located at the back of the jaw and plays a key role in elevating the mandible to facilitate chewing. It works in conjunction with other muscles, such as the temporalis and pterygoid muscles, to enable effective movement of the jaw during mastication.
The masseter muscle is lateral to the ramus of the mandible.
Mastication
You are in direct control of skeletal muscle.
Mastication, or chewing, involves a total of four muscles. These muscles are the masseter, temporalis, medial pterygoid, and lateral pterygoid.
