Angle of the mandible
|Angle of the mandible|
Human skull. Position of angle of the mandible shown in red.
Mandible seen from bottom. Position of angle shown in red.
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.
The forensic term for the midpoint of the mandibular angle is the gonion.
The mandibular angle has been named as a forensic tool for gender determination, but recent studies have called into question whether there is any significant sex difference in humans in the angle.
