What it is and what it does

The most massive muscle of the head in carnivores, thick and elastic. It arises from the temporal fossa (and from the sagittal crest) and inserts by a tendinous sheet on the coronoid process of the mandible. It closes the mouth, so it bites, and it guards the temporomandibular joint against forward luxation.

Worth remembering

It closes the mouth, so it gives the bite its force, and it guards the jaw joint.
