Which bone is the collarbone?

Explanation:
The bone known as the collarbone is the clavicle. It’s a slender, S‑shaped bone that runs horizontally from the sternum (breastbone) to the scapula (shoulder blade), forming the front part of the shoulder girdle. This position makes it the collarbone, and it acts as a brace that helps hold the arm away from the chest while also transmitting forces between the arm and the trunk. The other bones listed are the scapula (shoulder blade) which sits on the back, the humerus (upper arm bone), and the sternum (breastbone) in the center of the chest.
