This movement is caused by the The Temporomandibular Joint and the Muscles of Mastication. This articulation is a modified hinge type of synovial joint.
The articular surfaces are: (1) the head or condyle of the mandible inferiorly and (2) the articular tubercle and the mandibular fossa of the squamous part of the temporal bone.
An oval fibrocartilaginous articular disc divides the joint cavity into superior and inferior compartments. The disc is fused to the articular capsule surrounding the joint.
The articular disc is more firmly bound to the mandible than to the temporal bone.
Thus, when the head of the mandible slides anterior on the articular tubercle as the mouth is opened, the articular disc slides anteriorly against the posterior surface of the articular tubercle.
