Which bone lies on the thumb side of the forearm?

Explanation:
The forearm contains two long bones, the radius and the ulna. In the standard position with the palms facing forward, the radius sits on the thumb side (the lateral side), while the ulna is on the opposite side toward the little finger. Carpals and metacarpals are wrist and hand bones, not part of the forearm, which is why the thumb-side bone is the radius. The radius runs from elbow to wrist and rotates around the ulna when you turn your forearm (supination and pronation).
