The masseter muscle is lateral to the ramus of the mandible.
lateral pteregoid
the movement of mandible toward lateral causes movement in both right and left condyles. For example, if one moves one's mandible (lower jaw) toward right, the right conlye moves laterally and the left goes downward, forward, and medially, so the left condyle is defined as nonworking and the right condyle as working. the movement of nonworking condyle,in this example left condyle, forms an angle between sagittal plan and direction of nonworking condyle, which is called Bennett angle.

Lateral movements of diverging plates.
Lateral Pterygoid
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.
Sublingual and a portion of submandibular (lateral to sublingual) salivary gland.
Elevation
Motor neuron diseases like primary lateral sclerosis develop because the nerve cells that normally control the movement of voluntary muscles degenerate and die.
