Sliding / Gliding joint | both surfaces are essentially flat - limited movement - ex. rib/vertebrae or scapula/clavicle |
Condyloid joint | oval shaped process of one bone fits into the elliptical cavity of another - movement in two planes - flexion/extension and abduction/adduction - ex. wrist or atlas/occiput |
