Study Notes
Temporomandibular Joint (TMJ)
- The TMJ is composed of the mandibular fossa (temporal bone) and the condyle of the mandible.
Boundaries of the TMJ
- The boundaries of the TMJ include the articular disk, joint capsule, and lateral pterygoid muscle.
- The posterior boundary is NOT the maxillary sinus.
Classification of the TMJ
- The TMJ is classified as a ginglymo-arthrodial joint (a combination of hinge and plane joints).
Function of the Synovium
- The synovium produces synovial fluid, which provides nutrition and lubrication to the joint.
Mechanism of Lubrication
- The mechanism of lubrication in the TMJ involves the synovial fluid and the articular disk, which allows for smooth movement and reduces friction between the bones.
