Question

Do the bones of the upper jaw move? why?​

Answer 1

Answer:

No, the bones of the upper jaw can't move. We can move only the lower jaw because the upper jaw is connected with the skull by an immovable joint while the lower jaw is connected by a movable joint which makes the movement possible.
