Document Summary
Temporomandibular joint is the articulation of the condyle of the mandible and the mandibular fossa of the temporal bone. Divided by superior and inferior chambers by an articular disc , which permits lateral and medial excursion of the mandible. Temporomandibilar ligament on the lateral side-prevents posterior displacement of the mandible. Extend from the sphenoid bone to the ramus of the mandible. Stylomandibular ligament-extends from the styloid process to the angle of the mandible but is not part of the tmj proper. Tmj: is articulation of the condyle of the mandible with the mandiblar fossa of the temporal bone. Combine elements of the condyloid, hinge, and gliding joints. Function in the hingelike fashion whne the mandible is elevated and depresses, it glides slightly forward when the jaw is protracted to take a bite. Superior and inferior chambers, by articualr disx. Later and medial excursion of the mandible temporomandibular ligament.
