Articular capsule
innerlayer synovial membrane that secretes synovial fluid incapsulate the joint
Bursae
sac made synovial membrane contains fluid located where friction can occur ex, between anything and bones

protect reduce friction by lubracting the joint, supplying nutrients

depression
movement downward
protraction
movement forward
retraction
movement backward
