A articular cartilages provide smooth surfaces a. articular cartilage at bone ends is replaced with hyaline cartilage The sternoclavicular joint is also classified as a saddle joint. The mysosin heads propel the actin myofilaments toward the center of the sarcomere; this pulls the Z disks closer together, which shortens the sarcomere and the entire muscle A subtendinous bursa is found between a tendon and a bone. Friction between the bones is reduced by a thin layer of articular cartilage covering the surfaces of the bones, and by a lubricating synovial fluid, which is secreted by the synovial membrane.
