The stylomandibular ligament is the thickened posterior portion of the investing cervical fascia, which extends from near the apex of the styloid process of the temporal bone to the angle and posterior border of the angle of the mandible, between the masseter and medial pterygoid.
Articulation of the mandible. Medial aspect. (Stylomandibular lig. labeled at center left.)
Muscles of the pharynx, viewed from behind, together with the associated vessels and nerves. (Styl. mand. lig. labeled at center left.)
|From||styloid process (temporal)|
|To||ramus of the mandible|
From its deep surface some fibers of the styloglossus take origin.
Although classed among the ligaments of the temporomandibular joint, it can only be considered as accessory to it.
This ligament along with the sphenomandibular ligament is responsible for limitation of mandibular movements (limit excessive opening).
