What structure does the anterior articular disc connect to?

The anterior articular disc of the temporomandibular joint (TMJ) connects predominantly to the superior portion of the lateral pterygoid muscle. This connection is crucial because the lateral pterygoid is responsible for several functions, including the forward movement of the disc during jaw opening. The anterior articular disc serves as a cushion between the surface of the mandibular condyle and the temporal bone, and its attachment to the lateral pterygoid enables proper biomechanics, providing stability and facilitating movement during jaw actions such as speaking and chewing.

Understanding this relationship highlights the importance of the lateral pterygoid muscle in the functioning of the TMJ and how coordinated movements of the disc and the mandibular condyle are essential for normal jaw function.
