Angle of the mandible

The angle of the mandible (gonial angle) is located at the posterior border at the junction of the lower border of the ramus of the mandible.

The angle of the mandible, which may be either inverted or everted, is marked by rough, oblique ridges on each side, for the attachment of the masseter laterally, and the pterygoideus internus medially; the stylomandibular ligament is attached to the angle between these muscles.
