A Cats Lower Jaw Cannot Move Sideways. ~The Rapping Genius Lyriticus
The lateral pterygoid muscle is the muscle responsible for protruding the jaw, pulling the jaw sideways, and assisting in opening the mouth. It plays a key role in movements such as chewing and speaking.

Because your upper jaw is part of your skull which is connected to your spine and your lower jaw is connected to your upper jaw by a hinge type joint that allows you to move your lower jaw so that we can eat. So therefore we cannot move our upper jaw because that would require moving our head which would move our lower jaw too.
No. It is part of your skull so it doesn't move like your lower jaw. Your lower jaw moves because it is a separate bone attached to the tendons and muscles that move it.
Horses chew by moving their lower jaw in an oval pattern because their lower jaw is narrower than the upper jaw. As the jaw closes, it moves from one side to the other. As it opens it returns to the original position.
The medial pterygoid muscle, the left medial pterygoid will deviate the jaw to the right and vice versa.
The dog's jaw moves up and down and from side to side, in a grinding motion. The jaws move sideways across the teeth. The cat's jaw moves only up and down, there is no side to side grinding motion. There is no sideways movement.
The medial pterygoid muscle is responsible for elevating the jaw and closing the mouth. It also aids in moving the jaw from side to side during chewing.
No, crocodiles do not move their upper jaw; it is fixed in place. Instead, they primarily move their lower jaw to open and close their mouths. This anatomical structure allows them to exert a powerful bite, as the upper jaw serves as a stable platform while the lower jaw does the movement.
