Classification of joints

A joint is a site in the body where two or more bones meet. They can be classified according to their function and structure. Functional classification is based on the amount of movement there is between the articulating surfaces, where as structural classification is based on the presence or absence of a joint cavity.

There are three types of joint in the body:

• Fibrous or fixed
• Cartilaginous or slightly movable
• Synovial or freely movable
