The temporomandibular joint is the joint formed by the articulation of the mandible (lower jaw) with the skull. While the TMJ has many characteristics of other joints (knees, hips, shoulders, etc.), it is even more complex in its structure and function. Through a feat of mother nature we are capable of virtually unhinging the joint at its usual point of rest in order to move our jaws from side to side or to effect a wider opening. This complex movement during function necessitates a harmonious movement by the disc (meniscus) to maintain its protective position between the lower jaw and the skull. In this brief video you can see the normal action of the joint and the coordinated movement of the disc between the two bony surfaces.
