![]() Strengthens: strengthens the joint capsule.Type 2: extra-articular ligament (runs external of the articular cavity).Type 1: intracapsular ligament (runs within the articular cavity).Poorly elastic strand of connective tissue from parallel arrays of dense collagen fibers, which insert into the joint body or joint capsule.Type B cells = fibroblast-like synoviocytes that produce glycoproteins such as hyaluronan, a major component of synovial fluid.Type A cells = macrophage-like synoviocytes that maintain synovial fluid by removing debris.Contains two types of synovial cells, or synoviocytes.Composed of the tunica intima and tunica subintima.Composed of dense connective tissue (partially strengthened by ligaments).Most articular surfaces are covered with hyaline cartilage! There are two exceptions: the articular surfaces of the temporomandibular joint and sternoclavicular joint are covered with fibrocartilage!Īn envelope surrounding the joint that consists of an outer fibrous membrane and inner synovial membrane. Nourishes cartilage, which is a bradytrophic tissue.Reduces frictional forces caused by motion between articular surfaces.Clear viscous fluid in the articular cavity that is formed by the synovial cells of the joint capsule.Enables sliding and rotational motion free of interference.Space completely enclosed by the joint capsule in which the articulating bone ends are located.Formation of synovial fluid ( synovia) through the joint capsule mucosa.External closure of the intraarticular space, resulting in the formation of a closed articular cavity.Envelope surrounding the joint that consists of an outer fibrous membrane and inner synovial membrane.Enables bones to articulate with each other.Space between articulating bones that is filled with synovial fluid ( synovia) and is several millimeters in width.The resilience of cartilage protects the subchondral bones against mechanical stress.Enables low friction sliding and rotational motion in the joint.Layer of hyaline cartilage covering the articular surface of bones. ![]()
