Synovial Joints

feature     structure     function

hyaline cartilage - glassy smooth, spongy - prevent friction, absorb compression

joint capsule - tough fibrous capsule - strengthen joint, secrete synovail fluid

synovial fluid - slippery fluid - reduce friction, rid of waste debris, nourish catilage

ligament - stong fibrous tissue - connect bone to bone
