The articular disc is part of which joint?

Explanation:
The articular disc is a defining feature of the temporomandibular joint, which sits between the mandibular condyle and the temporal bone. This fibrocartilaginous pad divides the joint into two compartments, enabling both hinge movement (opening and closing the jaw) and gliding movement (forward and sideways motions). The disc helps reduce friction, absorb load, and keep the joint surfaces congruent as the jaw moves. While other joints like the knee have disc-like structures, they’re not typically called an articular disc in this context. Therefore, the joint that includes an articular disc is the temporomandibular joint.
