The gecko has a movable upper jaw. This is one of the reasons a gecko has such a strong and fierce bite.
The human jaw consists of two parts, one fixed and one movable. The fixed jaw is the maxilla (upper jaw) and the movable lower jaw is the mandible.
Upper jaw is stable and is not movable. Together with lower jaw, it forms a DYNAMIC masticating system. Together both jaws also help in phonation.
Only one, the mandible or lower jaw.Only one, the lower jaw or mandible.
mandible or lower jaw is the movable portion of our skull....
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 not because it does not really use the top jaw to move and chew with.
Only the jaw is moveable (also known as a lower mandible or jawbone).
It is the only movable jaw in our whole body. It is also known as the lower mandible. It helps us to talk, chew food, etc.
Upper jaw is a maxilla, and the lower jaw is a mandible.
the name for the upper jaw is maxilla and the name for the lower jaw is mandible
No both jaws on the fish are not equally movable, only the lower jaw (mandible) is movable to chew food
