What bone is also known as the collarbone?

The clavicle, commonly known as the collarbone, serves several essential functions in the human skeletal system. It acts as a vital connector between the arm and the body by linking the shoulder blade (scapula) to the breastbone (sternum). This structure is instrumental in facilitating a range of movements, including raising the arms and stabilizing the shoulders during various activities. Additionally, its location helps to protect important nerves and blood vessels that run in proximity to the upper limb.

In contrast, the scapula is the shoulder blade, which connects with the clavicle at the acromioclavicular joint. The humerus is the long bone of the upper arm that extends from the shoulder to the elbow. The sternum, or breastbone, is located in the center of the chest and connects with the ribs. Each of these bones has distinct roles within the skeletal framework and does not share the collarbone designation. Hence, the clavicle stands out due to its specific anatomical position and function associated with shoulder mobility and stability.
