For movement of the jaw, a joint exists (temporomandibular joint) between the head of mandible and the temporal bone. The strength of this joint depends mainly on the bony conformation and on muscles. A fibrocartilaginous disc caps the head of the mandible and projects forward, dividing the joint cavity into an upper and lower compartment. Movement can occur between the head and disc, and both can move together on the skull, providing a wide range of motion. The heads of the mandible can be palpated by passing a finger into your ear canal and then opening and closing your mouth, or wiggling the jaw from side to side. The various movements of the jaw are produced by the coordinated activity of the four ‘muscles of mastication’, medial and lateral pterygoids, temporalis, and the powerful masseter that clenches the teeth.
