It allows opening, closing, and a side to side movement of the mouth.he lower part of the joint permits elevation and depression of the mandible; opening and closing the mouth. Depression is mostly caused by gravity. However, if there is resistance, the digastric, geniohyoid, and mylohyoid muscles assist.

The Temporomandibular Joint (TMJ) Patient Information The two jaw joints are known as the temporomandibular joints (TMJs). They are ‘hinge and gliding’ type joints with discs similar to the knee joint. The rounded upper end of the lower jaw is known as the condyle and the socket is the fossa. The disc, which is tough and rubbery acts like a shock absorber and moves with the condyle during normal mouth opening and closing.

The TMJ allows the upper jaw to close on the lower jaw and is one of the most frequently used joints of the body.

The Muscles of Mastication The muscles of mastication are a group of muscles associated with movements of the jaw (temporomandibular joint). They are one of the major muscle groups in the head – the other being the muscles of facial expression. There are four muscles of mastication – the masseter, temporalis, medial pterygoid and lateral pterygoid. Embryologically, the muscles of mastication develop from the first pharyngeal arch. Consequently they are innervated by a branch of the trigeminal nerve (CN V), the mandibular nerve.
