Which bone is the shoulder blade?

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

Answer: (A)

The shoulder blade is the scapula. It’s a flat, triangular bone that sits on the back of the rib cage and forms part of the shoulder girdle, articulating with the humerus at the glenoid cavity to make the shoulder joint and with the clavicle at the acromion. The other bones have different roles: the clavicle is the collarbone that runs across the top of the rib cage, the humerus is the long bone of the upper arm, and the radius is one of the forearm bones. So the bone described as the shoulder blade is the scapula.
