What are the two long bones of the forearm collectively called?

Explanation:
Two long bones in the forearm are the radius and the ulna. They run from the elbow to the wrist and work together to rotate the hand; the radius is on the thumb side and the ulna on the pinky side in the standard anatomical position. The other bones listed—carpals (wrist), metacarpals (palm), and phalanges (fingers)—are not forearm bones. So radius and ulna is the correct pairing.
