Background

The connection between bones is called bone connection. Bone connections are further divided into direct and indirect connections, and joints are one form of indirect connection. A joint is generally composed of three parts, a joint surface, a joint capsule and a joint cavity. The articular surface is the contact surface of more than two adjacent bones, one is slightly convex and called as the articular head, and the other is slightly concave and called as the articular socket. The joint surface is covered with a smooth cartilage layer to reduce friction during exercise, and the cartilage has elasticity and can also reduce vibration and impact during exercise. The joint capsule is a tough connective tissue that firmly connects the adjacent bones. The outer layer of the joint capsule is a fibrous layer, the inner layer is a synovial layer, and the synovial layer can secrete synovial fluid to reduce friction during movement. The joint cavity is a narrow gap enclosed by joint cartilage and a joint capsule, and normally contains only a little synovial fluid.
