Which of these body parts is a bone?

Your clavicle (collarbone) is a long, slightly curved bone that connects your arm to your body. You’ll find one on both sides of the base of your neck. The bones help keep your shoulder blade in the correct position as you move. The word “clavicle” comes from the Latin “clavicula,” which translates to “little key.” The bone is actually shaped a bit like an old-fashioned key.
