lateral pterygoid, digastric, mylohyoid andgeniohyoid muscles
The temporalis and masseter muscles are the primary muscles responsible for raising the mandible (lower jaw) during the process of chewing or biting. These muscles work together to produce the necessary force to close the mouth and elevate the mandible.
The temporalis muscle acts to elevate and retract the mandible (lower jaw) during the process of chewing. It is one of the main muscles involved in mastication (chewing) and helps in closing the mouth during jaw movements.
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.
