Which bone is the long bone of the upper limb extending from the shoulder to the elbow?

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

Answer: (A)

The humerus is the long bone of the upper limb that extends from the shoulder to the elbow. It runs between the shoulder girdle (articulating at the glenoid) and the elbow (articulating with the radius and ulna), making it the main long bone of the upper arm. The radius is a forearm bone, while the scapula and clavicle are parts of the shoulder girdle and not the long bone that spans the upper arm.
