The collar bone that articulates with the scapula and sternum is the?

• A. Scapula
• B. Clavicle
• C. Sternum
• D. Radius

Answer: (B)

The collar bone is the clavicle. It spans from the sternum medially to the shoulder blade area laterally, forming the sternoclavicular joint with the sternum and the acromioclavicular joint with the scapula. This makes it the only bone that directly articulates with both the scapula and the sternum. The other bones don’t connect both of these together: the scapula mainly interfaces with the humerus and clavicle, the sternum connects with the ribs and clavicle but not with the scapula, and the radius is a forearm bone.
