Which TMJ ligament runs from the spine of the styloid process of the temporal bone to the angle of the mandible?

Which TMJ ligament runs from the spine of the styloid process of the temporal bone to the angle of the mandible?

• A. Stylomandibular (Posterior)
• B. Sphenomandibular
• C. Temporomandibular
• D. Capsular

Answer: (A)

The structure described is the stylomandibular ligament. It is a fibrous band that runs from the styloid process of the temporal bone to the angle of the mandible, providing a supporting connection on the lower border of the jaw. This path distinguishes it from the other TMJ ligaments: the sphenomandibular ligament extends from the spine of the sphenoid to the lingula of the mandible near the mandibular foramen; the temporomandibular ligament (lateral ligament) runs from the articular eminence and zygomatic process of the temporal bone to the neck of the mandible; and the capsular ligament forms the joint capsule around the TMJ. Thus, the attachment from the styloid area to the angle of the mandible points to the stylomandibular ligament.
