What bone is also known as the collarbone?

  1. Scapula

  2. Pelvis

  3. Clavicle

  4. Sternum

The correct answer is: Clavicle

The bone that is commonly referred to as the collarbone is the clavicle. This bone plays a crucial role in connecting the arm to the body, serving as a strut that supports the shoulder. The clavicle lies horizontally across the top of the chest and is situated between the sternum (which is the breastbone located in the center of the chest) and the scapula (which is the shoulder blade). Understanding the anatomy of the clavicle is important for estheticians, as it helps in comprehending the overall structure of the upper body and how it relates to posture and skin treatments. The collarbone also supports movement and stability in upper body activities, which may be relevant in discussions of body mechanics and ergonomics in esthetics.
