What is ball and socket joint and hinge joint?


Ball-and-socket Joints

Ball-and-socket joints are a type of Synovial joints or movable joints.

In this joint, the rounded head of one bone sits within the cup of another, which allows movement in all directions such as bending and circular movement as well as rotation of the limb.

For example- the hip joint, shoulder joint, and the first and second vertebrae of the neck that allows the head to move back and forth.

                                  


Hinge Joints

A hinge joint is a type of synovial joint that allows motion only in one plane.

These joints are formed when two or more bones meet and move along an axis to bend. 

Hinge joints are assisted by other tissues, including cartilage and ligaments, to connect and bend.

It is made up of an articular surface that is covered by hyaline cartilage and lubricated by synovial fluid.

Hinge joints are present in ankles, elbows, fingers, knees, and toes.
