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
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
A now uncommon procedure in which radiating incisions are made in the cornea (up to, but not through, its innermost layer) to reduce myopia.
Radial keratotomy has been largely replaced by laser procedures, such as LASIK, which carry less risk of permanent damage to the eye.... keratotomy, radial
an operation for short-sightedness (myopia). 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 This procedure is now rarely performed, having been superseded by *excimer laser treatment....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
flexion of the forearm (and sometimes also of the fingers) that occurs when the lower end of the radius is tapped. It is due to contraction of the brachioradialis muscle, which is stimulated by tapping its point of insertion in the radius.... radial reflex
