Study Notes
Temporomandibular Joint (TMJ)
- The articular surfaces of the TMJ are lined with fibrocartilage.
Joint Cavity
- The joint cavity of the TMJ is divided into two compartments.
Type of Joint
- The temporomandibular joint (TMJ) is considered a ginglymo-arthrodial joint as a whole.
Articular Surface
- The articular surface of the mandibular fossa in the TMJ is formed mainly by the squamous part of the temporal bone.
Glenoid Fossa
- The transverse ridge of dense bone in the glenoid fossa is tilted down to the occlusal plane at an angle of approximately 30 degrees.
