<P> In human anatomy , the biceps , also biceps brachii ( / ˈbaɪsɛps ˈbreɪki. aɪ / ) , is a two - headed muscle that lies on the upper arm between the shoulder and the elbow . Both heads arise on the scapula and join to form a single muscle belly which is attached to the upper forearm . While the biceps crosses both the shoulder and elbow joints , its main function is at the elbow where it flexes the forearm and supinates the forearm . Both these movements are used when opening a bottle with a corkscrew : first biceps unscrews the cork ( supination ) , then it pulls the cork out ( flexion ) . </P>
