What Is a Movable Joint?
A movable joint is the most common type of joint in the human body. Freely movable joints are found wherever movement is important. Movable joints are more commonly known as synovial joints because each contains synovial fluid &mdash a liquid that helps to decrease friction when the joint moves. Synovial fluid is found inside the synovial capsule of the joint. There are many types of movable joint such as hinge joints and saddle joints. Examples of movable joints include the elbow and shoulder joints. The elbow is a hinge joint that allows movement in a single plane. On the other hand, the shoulder joint is a ball and socket joint that allows a much wider range of movement.
