What lower arm bone is located on the thumb side?

Explanation:
In the forearm, the two bones are the radius and the ulna. The radius is the bone on the thumb side of the forearm. In anatomical position, the palm faces forward, so the radius sits on the lateral (thumb) side while the ulna is on the medial (pinky) side. The humerus is the upper arm bone, and the carpals are the wrist bones. So the bone located on the thumb side is the radius.
