dorsal
top of the foot or back of the hand
flexion
bending movement that decreases the angle between body parts
extension
straightening movement that increases the angle between body parts
abduction
movement away from the sagittal plane
adduction
movement toward the sagittal plane
circumduction
combination of abduction and adduction as well as flexion and extension
rotation
motion that occurs as one body part turns on an axis
opposition
motion in which body parts are brought together
pronation
rotary motion of the forearm inward
supination
rotary motion of the forearm outward
dorsiflexion
