3. is made of

   • The Synovial Joint
   • 2 x Articulating bones
   • Supported by ligaments
   • Smooth Hyaline (articular) Cartliage
     • Reliant on diffusion of nutrients from synovial fluid. This is because it has NO blood supply (or lymph vessels or nerve)
     • Type II Collagen
       • cover surface of cartliage and flatten with weight, spreading the load
     • Proteoglycans
       • Made of chrondrocytes (cartliage celles)
       • Act like a sponge , hold water but when joint is under load it is squeezed out and they reabsorb water when joint ceases to bear load
     • Water
   • Synovium (synovial membrane)
     • a fibrous cap lined with a very vascular membrane
     • Contains synovial cells
   • Synovial Fluid
     • produced by synovial cells, it is clear and straw coloured. Few WBC compared to plasma
     • found within the joint cavity
     • contains mucopolysachharides ( hyaluronic acid)
       • make the fluid more viscous than plasma
     • important in lubrication, shock absorption and nourishment
