Which ligament is described as running from the styloid process to the mandible?

• A. Stylomandibular Ligament
• B. Sphenomandibular Ligament
• C. Temporomandibular Ligament
• D. Capsular Ligament

Answer: (A)

Movement of the mandible is guided by several ligaments, each with specific attachments. The one that stretches from the styloid process of the temporal bone to the mandible is the stylomandibular ligament. Its position makes it the clear structure described, acting as a passive support and a check against excessive forward (protrusive) movement of the jaw. It lies outside the TMJ capsule, connecting the styloid process to the mandible rather than forming part of the joint itself.

The other ligaments have different attachments: the sphenomandibular ligament runs from the spine of the sphenoid to the lingula of the mandible and serves mainly as a paleosupport and a landmark for anesthesia; the temporomandibular ligament is part of the joint capsule, extending from the articular tubercle to the neck of the mandible; and the capsular ligament refers to the joint capsule itself rather than a distinct band from the styloid process.
