Which TMJ ligament is associated with the posterior aspect of the joint?

• A. Temporo (lateral)
• B. Spheno (medial)
• C. Stylo (posterior)
• D. Stylomandibular

Answer: (C)

The TMJ is stabilized by ligaments that anchor different regions of the joint. The ligament that runs from the styloid process to the mandible along the back part of the ramus sits closest to the posterior aspect of the joint, so it’s described as the posterior ligament of the TMJ. This stylomandibular ligament helps support and limit movements toward the back of the joint, distinguishing it from the lateral temporomandibular ligament, which reinforces the side of the joint, and from the sphenomandibular ligament, which is oriented medially and inferiorly.
