What is the bone in the forearm on the thumb side called?

Explanation:
In the forearm, there are two long bones: the radius and the ulna. The bone on the thumb side is the radius. In the standard anatomical position, the radius is on the lateral (thumb) side of the forearm, while the ulna sits on the medial (pinky) side. The humerus is the upper arm bone, and the carpals are the wrist bones. The radius also rotates around the ulna, enabling the forearm to turn the palm up or down (supination and pronation).
