a typical joint

A joint is the place where two or more bones make contact.[1] They allow movement (except for skull bones) and give mechanical support.[2]

Joints have cartilage in between them, which help to make the movement flexible. Joints are described structurally and functionally. Structural classification is how the bones connect to each other; function is the degree of movement between the articulating bones.
