<prompt> All muscles are useful in Supination and Pronation of Hand EXCEPTAnconeusBrachio-radialisSupinatorBiceps brachii  <response>: A Anconeus Supination Pronation are rotatory movements of forearm and hand around a vertical axis. In a semiflexed elbow, the palm is turned upwards in supination, and downwards in pronation Remember: Kings pronate, Beggars supinate The movements are permitted at the superior and inferior radioulnar joints, there is no middle radioulnar joint, and so no role. The radius is pronated by the pronator teres and pronator quadratus muscles. Pronation is performed by pronator quadratus and pronator teres muscle. Brachioradialis puts the forearm into a midpronatedsupinated position from either full pronation or supination. Hand is supinated by the brachioradialis, supinator brevis, and biceps muscles. The hand is supine in the anatomical position i.e., palms facing up during autopsy.This action is performed by the Biceps brachii and the Supinator muscle
