Which bone is on the thumb side of the forearm?

Explanation:
The radius is the bone on the thumb side of the forearm. In the standard anatomical position, the forearm is oriented so the palm faces forward, placing the radius on the lateral (thumb) side and the ulna on the medial (pinky) side. The humerus is the upper arm bone, and the carpals are the wrist bones. The radius articulates with the wrist bones and can rotate around the ulna when you turn your hand, which is why it sits on the thumb side.
