pronation

 [pro-na´shun]
the act of assuming the prone position, or the state of being prone. Applied to the hand, turning the palm backward (posteriorly) or downward, performed by medial rotation of the forearm. Applied to the foot, a combination of eversion and abduction movements taking place in the tarsal and metatarsal joints and resulting in lowering of the medial margin of the foot, hence of the longitudinal arch.
Pronation (top) versus supination (bottom).

pro·na·tion

(prō-nā'shŭn), [TA]
The condition of being prone; the act of assuming or of being placed in a prone position; a specific rotational motion of the forearm that moves the palm into a downfacing position, a specific rotational motion of the foot in which the plantar surface is rotated outward.
Synonym(s): pronatio [TA]

pro·na·tion

(prō-nā'shŭn) [TA]

pronation

The act of turning to a face down (prone) position, or of rotating the horizontal forearm so that the palm of the hand faces the ground. The opposite movements are called supination.
