A space between the two bones of the synovial joint is called the joint cavity. It allows the synovial joints to move freely. The layer of hyaline cartilage covers the bones of the synovial joints. This is called articular cartilage. It forms a slippery surface to cover the bones. Due to the presence of cartilage, the friction is reduced between bones of the joints during movement.
Synovial joints may also have accessory ligaments present outside or within the articular capsule of the joints. Nerve endings are present in the articular capsule and the related ligaments of these joints. Similarly, blood vessels enter the ligaments and articular capsule of these joints.
