Clavicle

Long bone that serves as a strut between the scapula and the sternum

The clavicle, collarbone, or keybone is a slender, S-shaped long bone approximately 15 centimetres (6 in) long that serves as a strut between the shoulder blade and the sternum (breastbone). There are two clavicles, one on each side of the body. The clavicle is the only long bone in the body that lies horizontally.
