The masseter muscle is lateral to the ramus of the mandible.
The Mandible. The Coronoid process a prominent projection just anterior to the Condylar Process.
The lateral pterygoid muscle has a triangular shape, with two heads; superior and inferior. It has horizontally orientated muscle fibers, and is the major protractor of the mandible.
The jaw bone or mandible is located in the head, it is the only skull bone that moves. It is fairly simple to judge where it is, below the bottom teeth. To find it put your hand on your chin, that's it, then to find the ramus (at the back) slide your hand round the side at the bottom until you come to a shapr upwards corner, this is the ramus.
The masseter IS the functional muscle which closes the mandible (jaw).
Masseter, Lateral pterygoid, Temporalis.

The ramus is the ascending part of the mandible.

Lateral pterygoid (HOLES book, pg 155 part a )
The lateral pterygoid muscle has a triangular shape, with two heads; superior and inferior. It has horizontally orientated muscle fibers, and is the major protractor of the mandible.
Ramus (plural rami)
Lateral Pterygoid
The masseter muscle is the chewing muscle covering the angle of the mandible. During bilateral contraction, the muscle elevates the mandible, raising the lower jaw.
middle and internal layers of the lateral muscles
Gravity plays a large part in opening the jaw, but there are muscles that help forcefully open your jaw. The most important of these is the digastric muscle, which connects from the mastoid process of the temporal bone to the hyoid bone, and then from the hyoid bone to the digastric fossa of the mandible.
