The BicErs (bis— xscpuka! two heads) arises by two tendons, onethe short head, from the coracoid piocess in common with the coraco-brachialis; the other the long head, from the upper part of the glenoidcavity. The muscle is inserted by a rounded tendon, into the tuber-cle of the radius. The long head, a long slender tendon, passesthrough the capsular ligament of the shoulder-joint enclosed in asheath of the synovial membrane ; after leaving the cavity of thejoint, it is lodged in the deep groove that separates the two tuberosi-ties of the humerus, the bicipital groove. A small synovial bursa isinterposed between the tendon of insertion, and the tubercle of theradius. Jit the bend of the elb
