Answer 3
Upper jaw
is an immovable joint
Fish

Question 4
Answer the following:
(a) What is a ball and socket joint?
(b) Which of the skull bones are movable?
(c) Why can our elbow not move backwards?
Answer 4
a) This is the type of joint in which The rounded end of one bone fits into the cavity (hollow space) of the other
bone. Such a joint allows movements in all directions which is called as ball and socket joint. for ex:bones of
hip
b) Lower jaw is movable
c) Our elbow join is a example of hinge joints which only allow back to forth movements. So it cannot move
backwards
