Temporalis and masseter muscles.
Temporalis muscle
muscles of mastication

The masseter and the temporalis elevate the mandible. The Pterygoid muscles do varies movements of the jaw. All together it allows us to chew various foods at differient consistencies.

Gravity plays a large part in opening the jaw, but there are muscles that help forcefully open your jaw. The most important of these is the digastric muscle, which connects from the mastoid process of the temporal bone to the hyoid bone, and then from the hyoid bone to the digastric fossa of the mandible.
The lateral pterygoid muscle has a triangular shape, with two heads; superior and inferior. It has horizontally orientated muscle fibers, and is the major protractor of the mandible.
Rhomboids
A person has two jaw bones. One upper jaw bone called the maxilla and the lower bone called the mandible. The maxilla doesn't move but the mandible does. The muscle (masseter) that closes the two is one of the strongest muscles in the human body.
