Which bone is the shoulder blade that connects the humerus with the clavicle?

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

Answer: (C)

The scapula, or shoulder blade, is the flat triangular bone of the shoulder girdle. It sits on the back of the rib cage and forms important connections: it provides the socket (the glenoid cavity) for the head of the humerus, creating the shoulder joint, and its lateral edge articulates with the clavicle at the acromioclavicular joint. This is why it’s the bone that links the humerus with the clavicle, enabling the wide range of shoulder movements. The humerus is the upper arm bone that fits into the scapula's glenoid cavity, while the radius and ulna are forearm bones that connect at the elbow, not to the clavicle.
