Which bone is known as the collarbone?

The bone commonly referred to as the collarbone is the clavicle. This bone serves several important functions in the human body. It acts as a strut that connects the arm to the body, specifically linking the shoulder blade (scapula) to the sternum (breastbone). The clavicle's S-shaped structure allows for increased mobility of the shoulder while also providing support and stability during arm movement. Additionally, it serves as an attachment point for several muscles, including those involved in movements of the arm, neck, and chest.

Understanding the role and location of the clavicle in relation to other bones is crucial in appreciating its significance in both anatomy and movement. Other bones mentioned, such as the scapula, sternum, and humerus, serve different functions and are located in other parts of the body, highlighting the specific identity and unique role of the clavicle as the collarbone.
