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> <P> The biceps is a muscle in the upper arm with two heads, called the short head and the long head, which converge into a single mass . It is one of the three muscles in the anterior compartment of the arm, the others being the brachialis muscle and the coracobrachialis muscle, with which the biceps shares a nerve supply . Both heads of the biceps arise from the scapula in the shoulder, and the muscle attaches to the radius (bone), in the forearm . Specifically, the short head of the biceps originates from the coracoid process at the top of the scapula . The long head originates from the supraglenoid tubercle just above the shoulder joint . From here, the long head has a tendon that passes up along the intertubercular groove of the humerus into the joint capsule of the shoulder joint . The tendon of the short head runs adjacent to the tendon of the coracobrachialis and likewise attaches to the coracoid process . </P>
