Ligament
Dense regular connective tissue
Tough slightly elastic
Resists strain, prevents extreme movement
Prevent injury
Synovial fluid
In space enclosed by articular capsule
Lubrication
Shock absorber
Joint mobile, smoother movement
Articular cartilage
Thin layer lining ends of bones
Minimise friction
Stops bones grinding
Joint capsule
2 layers of tissues outside of joints
Support
Nutrient exchange between blood and joint
Prevent injury
Bursa
Sac filled with synovial fluid
Placed at key points of friction in a joint
Free movement
Reduces pain
