The diagrams above show muscles in the mouth area that are not strictly speaking muscles of facial expression. There are more muscles in these areas than illustrated here. Top: Pterygoids and Hyoids. 2nd: Pterygoids. 3rd: Pterygoids from inside jaw. Last: Hyoids and hyoid bone.

The Pterygoid muscles, internal and external, are muscles of mastication and function to position the jaw. The Mylohyoid and Geniohyoid help position the hyoid bone and larynx, and are important in swallowing.

Jaws of a biting cat compared to a sabretooth cat. Sabretooth cat skulls were designed for a swift downward strike of the sabre-teeth, not a strong bite. The coronoid process was also greatly reduces, meaning the jaws were weakly bound to the skull and couldn’t withstand much bending or twisting.
