2 Joints
The main types of joints found in the body are classified as synovial joints.
Synovial joints (diarthroses)
Features of a typical synovial joint (Fig. 2.1)
Articular hyaline cartilage covers the articular surfaces.
A fibrous capsule surrounds the joint.
Synovial membrane lines the joint, except where articular hyaline cartilage is found.
A lubricant film of synovial fluid is secreted into the joint cavity by the synovial membrane.
Ligaments strengthen the joint capsule. These may be separate from the capsule or may blend with it.
Movement occurs at the joint but the amount varies with the type of synovial joint.
Nerves and blood vessels supply the joint.
Intracapsular structures may be present, e.g. tendons, ligaments, joint discs, pads of fat.
