Knee, elbow, hip, shoulder Smooth articular cartilage & cavity with fluid Membrane lining = synoviocytes 2 types  Type A – macrophages-phagocytosis  Type B – fibroblast – produce hyaluronic acid, fibronectin and collagen An ultrafiltrate of plasma. Nonselective filtration – no large proteins, Reference ranges are like that of plasma- Table 12-1 Function Damage to membrane creates pain  Reduce friction and stiffness= arthritis  Lubricate the joint Common test are in Table 12-1  Nutrients to the cartilage  Reduces shock during compression during activities C L A S S I F I C AT I O N S Four classifications of disorders (arthritis) 1. Noninflammatory: degenerative, osteoarthritis 2. Inflammatory: immunologic, lupus erythematosus (LE), rheumatoid arthritis (RA), Lyme disease Crystal-induced, gout and pseudogout 3.
