Which bone is located in the upper arm and runs from shoulder to elbow?

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

Answer: (B)

The main idea is identifying the bone that forms the upper arm and spans from shoulder to elbow. That bone is the humerus. It is the long bone of the upper limb, connecting at the shoulder joint with the scapula to form the shoulder, and at the elbow with the two forearm bones, the radius and ulna. The radius and ulna are located in the forearm, extending from the elbow to the wrist, not in the upper arm. The clavicle, or collarbone, sits above the shoulder girdle and does not run from shoulder to elbow like the humerus.
