Explanation: 

Detailed explanation-1: -The temporomandibular joint (TMJ), also known as the mandibular joint, is an ellipsoid variety of the right and left synovial joints forming a bicondylar articulation.

Detailed explanation-2: -The TMJ differs from most synovial joints in several ways. First, the TMJ forms by appositional growth, as opposed to segmentation of a continuous skeletal condensation. Second, in the TMJ, the articular surfaces of the condyle and glenoid fossa are covered by a layer of fibrous rather than hyaline cartilage.
