Question

Name the freely movable joints in body. Explain them briefly.

Answer 1

Freely movable joints allow free movement in various directions. There are four types of these joints present in our body. They are:
1. Ball-and-socket joint: In this type of joint, the ball of one bone is fitted in the socket of another bone. Such joints are found in hips and shoulders.
2. Pivot joint: In this type of joint, the rounded surface of one bone fits into a ring formed by the other bone. Pivot joints occur between the first two vertebrae of the backbone.
3. Hinge joint: It allows the angular movement of bones in one plane only. Such joints are found in knee and ankle.
4. Gliding joint: In this type of joint, one bone slips over the other bone at the place of the joint. It allows sliding movement in which two bones can slide over each other.
