Question

Describe the different kinds of joints and the places where each one is found in the body and how they help in movement.

Answer 1

The different kinds of joints, their positions and their help in movement are as follows:

1. Ball-and-socket joints: The ball-like cavity fits into a cup-like hollow cavity of other bone. They are found in the hip and the shoulder and allow movement in all directions.
2. Pivot joints: The rounded surface of one bone fits into the ring formed by the other bone in such a way that one bone is able to rotate over the other. They are found in the joint of neck and head.
3. Hinge joints: These joints are found in the knee and the elbow and allow back-and-forth movement.
4. Gliding joints: These joints allow bones to glide over each other. These joints provide little movement in all directions and are found in the bones of the skull.
