aka
Synovial Cavity
contains synovial fluid
lubricates the joint
increases nutrients
decreases wastes
Diarthrotic Pivot Joint
atlantoodontoid
radioulnar (proximal & distal)
uniaxial
right/left rotation
medial/lateral rotation
pronation/supination
Diarthrotic Saddle Joint
first carpometacarpal (thumb)
biaxial
flexion/extenstion
abduction/adduction
combined movement = opposition
Articular Cartilage
protects bone
