Answer 2

Answer:

Only one skull bone is movable that is the mandible.  

Explanation:

The mandible is attached to the temporal bone forming the temporomandibular joint. The joint is of hinge type of synovial joints. It can form elevation, depression, retraction and protrusion of the joint.  

This joint helps in ‘movement of the jaw’ while chewing the food. All other ‘bones of the skull’ are immovable and are attached to each other by teethed appearance known as the sutures.
