Which long bone runs from the shoulder to the elbow?

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

Answer: (A)

The upper arm bone that spans from the shoulder to the elbow is the humerus. It’s the long bone in the arm, connecting proximally with the shoulder girdle at the glenohumeral joint and distally with the forearm at the elbow. The radius and ulna are forearm bones that run from the elbow to the wrist, not from shoulder to elbow, and the scapula is a flat shoulder blade, not a long bone that extends between the shoulder and elbow. So the bone that runs from shoulder to elbow is the humerus.
