What are two muscles that connect to the mandible and cranium and close the jaw?
Masseter, Lateral pterygoid, Temporalis.
What is the jaw called?
Upper jaw is a maxilla, and the lower jaw is a mandible.
Why does your jaw crack when you open your mouth?
Massage your jaw muscles(inside and outside of your mouth), your jaw is probably tight on one side and is pulling the disc out of alignment when you open and close your jaw. Don't do it on purpose for kicks, either -- it can start a chronic pain condition called jaw clenching or teeth grinding that is difficult and sometimes expensive to fix.
What is a phossy jaw?

Why can you move your lower jaw and not the upper jaw?
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.
What muscle can close the jaw and pull it sideways?
The medial pterygoid muscle, the left medial pterygoid will deviate the jaw to the right and vice versa.

Which type of muscle helps you move your jaw to chew food?
The upper jaw is attached to the skull and therefore can not move. It is the lower jaw that is able to move. Several muscles are involved, sometimes working together to cause the desired movement. The jaw can move in primarily three motions, down or open, up or closed, and laterally to the right or left. The muscles used to close the jaw are primarily the two Masseters, the two Medial Pterygoids, and the two Temporalis muscles. The Lateral Pterygiod muscles work with the Medial Pterygoid muscles on the same side to move the jaw laterally to the right or left, and if both Lateral Pterygoid muscles are contracted simultaneously, the lower jaw slides forward protruding the chin. The anterior fibers of the Temporalis also help in protruding the jaw and it's posterior fibers pull it back. Opening the jaw is a bit more complicated. The primary muscles used are the Digastric muscles. What complicates the situation is that they pull off the hyoid bone. The hyoid bone is stabilized by the Sternohyoid, Stylohyoid, Omohyoid, Thyrohyoid, and Mylohyoid muscle pairs. Without stabilization of the hyoid bone, the Digastric muscles could not work, so, indirectly they are involved in opening the lower jaw. When opening really wide, the Lateral Pterygoids pull the jaw forward in addition to the rotation caused by the Digastrics.
What muscle opens and closes your jaw?
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.
Can you work out your jaw muscle?
Sure you can -- there are several different muscles on the jaw, including the masseter, temporalis, medial pterygoid, and lateral pterygoid -- all used for chewing. Have you ever chewed a piece of gum for a long time and had your jaw get tired? You overworked those muscles, specifically you would feel it more in your masseter (which runs down your cheek to your jaw and is what opens your mouth, and your temporalis, which runs over your temple to your jaw which closes your mouth. The pterygoid muscles move your jaw laterally, or side to side. Having oral... you know what I mean... Can also BENEFIT ... and help WORK... those jaw muscles.

How does the movement of a cat's jaw differ from that of a dog's?
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.
What are various muscles assisting in mastication?
The four main muscles involved in mastication, or chewing, are the masseter, the temporalis, the medial pterygoid and the lateral pterygoid. Muscles associated with the hyoid, such as the sternohyomastoid, also helps to open the jaw.
Do horses chew sideways?
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.
