Radial Nerve

This NERVE arises from the BRACHIAL plexus in the axilla. At ?rst descending posteriorly and then anteriorly, it ends just above the elbow by dividing into the super?cial radial and interosseous nerves. It supplies motor function to the muscles which extend the arm, wrist, and some ?ngers, and supplies sensation to parts of the posterior and lateral aspects of the arm, forearm and hand.... radial nerve

Radial Artery

This artery arises from the brachial artery at the level of the neck of the radius. It passes down the forearm to the wrist, where it is easily palpated laterally. It then winds around the wrist to the palm of the hand to supply the ?ngers. (See ARTERIES.)... radial artery

Deep cuts into the tissue of the cornea are placed radially around the outer two-thirds of the cornea; this flattens the curvature of the central part of the cornea and reduces the myopia. This procedure is now rarely performed, having been superseded by *excimer laser treatment.... radial keratotomy

Radial Reflex
