Answer 1

Types of joints: 1 Mark each

1. Fixed or immovable joints are the joints which do not allow the bones to move but they offer protection for the structure in which they are present. Examples are the sutures between the bones of the cranium, ribs in the breastbone and bones of the hip girdle.

2. Slightly movable joints provide support to the structure in which they are present. They also help the structure to move slightly. An example is the joint in the lower jaw which is slightly movable.

3. Freely movable joints are the joints which help in the movement of the part in which they are present. There are four freely movable joints present in our body - ball and socket joint, Pivot joint, hinge joint and the gliding joint.
