Anatomical terminology

It is broader above than below, and its fibers are directed obliquely downward and backward.

It is covered by the parotid gland, and by the integument.

It prevents posterior displacement of the mandible and prevents the condyloid process from being driven upward by a blow and fracturing the base of the skull.
