Unlike lower jaw, upper jaw
cannot be moved away
from the head. There is a joint
between the upper jaw and the head which is a fixed joint.
Audio ScriptNot all the parts of the body with joints can be moved. There are bones in your head which are joined at various points. However, the bones cannot move at those joints. Such joints are called fixed joints.TOS (Text On Screen)
Joints at which bones cannot be moved are called fixed joints.
