Mastication is what those muscles can help you do.
Temporalis, Masseter and the Medial Pterygoid
They are responsible for mastication process (i.e)chewing the food
Mastication, or chewing, involves a total of four muscles. These muscles are the masseter, temporalis, medial pterygoid, and lateral pterygoid.
both masseter and temporalis
The chief muscles are: Masseter Temporalis or Temporal Internal (medial) pterygold External (lateral) pterygold
The four main muscles involved in mastication, or chewing, are the masseter, the temporalis, the medial pterygoid and the lateral pterygoid. Muscles associated with the hyoid, such as the sternohyomastoid, also helps to open the jaw.
arbiculariy oris, arbiculary occuli, masseter, zygomatic major, deppressor anguli oris, temporalis, occipitalis, frontalis, rissourios, platysma
The masseter IS the functional muscle which closes the mandible (jaw).
The muscle that aids the jaw in closing is the temporalis muscle. The masseter is the muscle that primarily moves the jaw.

Masseter
You use at least 4 muscles to chew; the one you're probably looking for is the masseter. It's assisted by the temporalis and the medial and lateral pterygoids to complete the grinding. Of course there are other muscles that help too, like your tongue and cheek muscles.
