circular movement around an axis: dorsiflexion: decreasing the angle of the ankle joint so that the foot bends backwards (upward) plantar flexion: the motion that extends the foot downward toward the ground as when pointing the toes: plant/o: sole of the foot: supinaton: as applied to the hand, the act of turning the palm forward, or up: pronation
Inversion is where the sole of the foot is turned inwards, plantar flexion is where the foot and toes point downwards and adduction of the ankle involves the toes pointing across the body. Combine all three movements and you have supination.
