| to extend so that the angle between bones of a joint is greater than normal | hyperextension |
| a bending movement around a joint in a limb (as the knee or elbow) that decreases the angle between the bones of the limb at the joint | flexion |

| medial rotation of the forearm, with the palm in a downward (Prone) position so the radius lies diagonally across the ulna | pronation |
| the movement of turning the sole of the foot outward, away from the midline | eversion |
| Reaching out or pushing with you arm and hands | protraction |
| The location of the thumb opposite to the fingers so that the hand can grasp objects | opposition |
