The temporomandibular ligament plays a crucial role in the stability of the temporomandibular joint (TMJ), which connects the lower jaw (mandible) to the skull. This ligament provides support to the joint during various movements, such as chewing and speaking, ensuring that the mandible articulates smoothly with the temporal bone of the skull. By stabilizing the joint, it helps prevent dislocation and maintains proper alignment during jaw movement.

The other choices do not accurately describe the function of the temporomandibular ligament. While the tongue is important for various functions, including speech and swallowing, the temporomandibular ligament does not support the tongue. Additionally, while the ligament does help connect the jaw to the skull indirectly by stabilizing the joint, its primary function is not as a connector; rather, it provides stability during movement. Lastly, assisting in the movement of the mandible may occur as a result of stabilization, but the primary role of the temporomandibular ligament focuses on maintaining the integrity of the joint itself, rather than directly facilitating movement.
