Question

What is a joint? How can you classify joints on the basis of the movement they allow?

Answer 1

A joint in the body is a place where two bones are joined together. A joint is strong enough to withstand jerks. The bones are held together at the joints by strong, elastic bands called ligaments.
The joints can be classified into following three types depending on the type of movement they allow:
(a) immovable,
(b) slightly movable, and
(c) freely movable.
