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
The analogous action to wrist flexion is one that would tip the sole of the foot downward, increasing the angle between foot and leg. The usual term for the increase in such an angle would be extension, but in order to emphasize the relation between foot and hand, this action is instead termed plantar flexion .
