Which bone is the shoulder blade?

Which bone is the shoulder blade?

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

Answer: (B)

The shoulder blade is the scapula, a flat triangular bone that sits on the back of the rib cage and forms part of the shoulder joint. It provides attachment points for muscles and, with the humerus, allows the arm to move in many directions. The clavicle is the collarbone that runs horizontally across the top of the chest, the humerus is the upper arm bone, and the pelvis is the hip bone. So the correct name for the shoulder blade is the scapula.
