| diarthrotic | movable. Synovial joints (most joints) |
| ball & socket joint | hips |
| saddle joint | thumb |
| hinge joint | elbow, knee, fingers |
| gliding joints | carpals, tarsals |
| pivot joints | radius, ulna |
| ellipsoid or condyloid joints | intercarpal joints of wrist, sernocalvicular, between facets of spinal vertebreae |
| movement: adduction | moving medially (adding to body) |
| movement: abduction | moving laterally, away from body |
| movement: flexion | bring in closer to keep joint tighter together |
| movement: dorsiflexion | moving ankle so back of foot (dorsal) side moves up |
| movement: plantar flexion | moving ankle so foot moves toward plantar side (bottom) |
| movement: pronation | turning hand down toward ground |
| movement: supination | turning hand up as if holding a soup bowl |
| movement: extension | moving knee so leg is stretched outward from body. (or arm) |
| movement: inversion | turning foot so plantar surface faces in, medially, toward body |
| movement: eversion | turning foot outwards so plantar surface faces laterally, away from body |
| movement: circumduction | circular movement of hips or shoulders |
| movement: scapula, lateral | holding arm up so scapula moves laterally |
| movement: scapula, neutral | arm at side, "resting" position of scapula |
| movement: scapula, medial | arm downward moving medially against back |
| movement: scapula anterior tilt | rolling shoulders forward |
| movement: scapula , elevation and depression | moving shoulder up or down |
