<P> The clavicle or collarbone is a long bone that serves as a strut between the shoulder blade and the sternum or breastbone . There are two clavicles , one on the left and one on the right . The clavicle is the only long bone in the body that lies horizontally . Together with the shoulder blade it makes up the shoulder girdle . It is a palpable bone and in people who have less fat in this region , the location of the bone is clearly visible , as it creates a bulge in the skin . It receives its name from the Latin : clavicula ( `` little key '' ) because the bone rotates along its axis like a key when the shoulder is abducted . The clavicle is the most commonly fractured bone . It can easily be fractured due to impacts to the shoulder from the force of falling on outstretched arms or by a direct hit . </P>
