Which of the following ligaments is not among the primary stabilizers of the TMJ?

Explanation:
The TMJ is held primarily in place by the tough joint capsule and the thick lateral (temporomandibular) ligament that reinforce the capsule and stabilize the condyle during function. The two extracapsular ligaments, sphenomandibular and stylomandibular, provide passive support and help limit extreme movements, but they aren’t the main stabilizing structures of the joint in normal activity. The stylomandibular ligament, running from the styloid process to the mandible, mainly acts as a check on opening and offers only passive support, so it isn’t considered a primary stabilizer of the TMJ.
