MUSCULOSKELETAL SYSTEM Dr Mokhber The Development of a Synovial Joint Types of Joints (1) 134 joints are in body Synarthroses (syndesmosis) Skull Sutures Amphiarthroses (synchondrosis) Pubic Symphysis ,intervertebral disc Diarthroses Synovial Joints ❖Saddle: CMC Ball & socket: Hip, Shoulder Pivot: Atlantoaxial Condyloid: Radiocarpal Planar (Gliding): Carpal Bone, AC, Patella Hing: Elbow, Modified (Knee) Synovial Joint Capsule, Ligament, Tendon (Type I Collagen) Synovium Cartilage (Type II Collagen) Bone (Type I Collagen) Synovium (1) Physiologic role of Synovium: 1) Secretion of synovial fluid 2) Synthetic activity 3) Immunologic role Synovium (2) Synovial Histology: 1) Synoviocytes (10-20%) Type A, Macrophage-like (80-90%)Type B, Fibroblast-like 1) Synovial stroma 2) Synovial vasculature Structure of Synovium Synovial Fluid Function: Nutrition & Lubrication. Production: Plasma Ultrafilterate+ Generated Factors (Hyaluronic acid, Lubricin, Regulatory factors). Clearance Cellular Composition:
