Joint capsule and ligaments of temporomandibular joint

The TMJ is surrounded by a joint capsule. It encloses the joint and attaches along the articular surfaces. The joint capsule goes in front of the articular eminence (tubercle), along the sides of the mandibular fossa, and finally, it attaches in the front of the petrotympanic fissure that is located on the back of the joint. The capsule inserts at the neck part of the mandible, usually above the pterygoid fovea.
