Which bone is known as the shoulder blade?

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

Answer: (A)

The shoulder blade is the scapula. It sits on the back of the rib cage as a flat, triangular bone that forms the posterior part of the shoulder girdle. The scapula connects with the humerus at the glenoid cavity, creating the shoulder joint, and it interfaces with the clavicle at the acromion region, contributing to the overall shoulder mobility and strength. It also serves as a major site for muscle attachments, including the rotator cuff muscles, which help stabilize and move the arm. The other bones mentioned are not the shoulder blade: the clavicle is the collarbone, running horizontally across the top of the chest; the sternum is the breastbone in the center of the chest; and the scaphoid is a carpal bone in the wrist.
