Temporomandibular joints
The temporomandibular joints connect the mandible to the temporal bones. Each is a synovial joint in which the mandibular condyle articulates with the mandibular fossa and articular eminence, separated by an articular disc.
Function
Allows both hinge (rotation) and gliding (translation) movements, so the jaw can open widely and move side to side.
Clinical relevance
Temporomandibular disorders (TMD) can cause pain, clicking and limited opening.
Location
The movement control illustrates rotation below the disc and forward/downward translation of the condyle–disc complex along the articular eminence. Rotation and translation overlap; this model uses an illustrative motion path.
