Joint feature - Structure - Function
- Joint capsule - Fibrous tissue encasing joint - Forming capsule around joint adds stability
- Articular discs of cartilage - C-shaped rims of fibro cartilage - Shock absorbers
- Synovial fluid - Fluid that fills joint capsule - Nourishes and lubricates articular cartilage
- Synovial membrane - Lines joint capsule - Secretes synovial fluid
- Articular Cartilage - Covers articulating surfaces of bones - Prevents friction between bones
- Bursa - Sac filled with synovial fluid located between tendons/ligaments and bone - Reduce friction where tendons/ligaments/muscles/bones rub together
- Ligaments - White fibrous tissue, connects bone to bone - Securing bones of joint, stability
- Pads of fat - Fatty tissue between fibrous capsule and bone/muscle - Cushion between joint capsule and bone/muscle
