Types of joints:

 Joint is the location at which two or more bones make contact. They movement and provide mechanical support. Joints can be classified on the basis of the degree of movement they allow:

Immoveable (fixed) joints: such joints allow no movement e.g. the joints between the skull bones.

Slightly moveable joints: such joints allow slight movements e.g. joints between the vertebrates.

Moveable joints: they allow the variety of movements e.g. shoulder joint, ship joints, elbow joint, knee joint, etc. There are many types of move able joints in body. The main types are hinge joints and ball and socket joints. Hinge joints move back and forth like the hinge on a door and allow movements in one plane only. The knee and elbow are hinge joints. Ball and socket joints allow movement in all directions. The hip and shoulder joints are ball and socket joints.
