Question

What are the different types of freely movable joints?

Accepted Answer

There are four major types of freely movable joints:

1. Ball and socket joint: In this joint, the ball-like end of one bone fits into a cup-like cavity (socket) of the other bone. This type of joint allows movement in all directions.
Example: Joint at the hip, etc.

2. Pivot joint: This type of joint allows only rotation. The rounded surface of one bone fits into a ring formed by the other bone so, that one bone is able to rotate over the other in a ring. Example: Joint between the neck and the head.

3. Hinge joint: This type of joint allows the movement in one direction only, just similar to the hinges of a door. Example: Elbow joint between the upper and the lower arm.

4. Gliding Joint: This type of joint allows the bones to glide over each other, side to side, as well as backward and forward movement. Only a slight movement takes place in this joint. Example: Joints between the bones of the ankle.
