Which bone is commonly referred to as the collarbone?

The bone commonly referred to as the collarbone is the clavicle. The clavicle is a key skeletal element that connects the arm to the body, specifically the sternum at one end and the scapula at the other. Its distinct shape allows it to function as a strut, helping to stabilize the shoulder and allowing for a greater range of motion in the arm. The clavicle also plays a crucial role in protecting the neurovascular bundle that supplies the arm, as well as serving as an attachment point for several muscles. Its location and structure make it an easily identifiable bone in the human anatomy, often visible and palpated under the skin, giving rise to its nickname as the collarbone.
