Which bone is known as the collarbone?

• A. Carpals
• B. Humerus
• C. Scapula
• D. Clavicle

Answer: (D)

The name used for the bone known as the collarbone is the clavicle. It runs horizontally across the top of the chest, connecting the sternum at the center of the chest to the scapula at the shoulder blade. This position makes the clavicle a key part of the shoulder girdle, acting as a strut that keeps the arm away from the body to allow wide shoulder movement, while also helping protect the underlying nerves and blood vessels that travel toward the arm. The other bones listed are different: carpals are the eight wrist bones, the humerus is the long bone of the upper arm, and the scapula is the shoulder blade. So the collarbone is the clavicle.
