Which bone is the longer of the two forearm bones and lies on the outside of the little finger?

Explanation:
Forearm bone anatomy: there are two long bones—the radius and the ulna. The ulna is the longer of the two and lies on the little finger side of the forearm. In anatomical position, that means it runs along the medial (pinky) side from elbow to wrist, while the radius is on the thumb side and is typically shorter. So the bone described is the ulna. The other options aren’t forearm bones—tibia is in the leg, vertebrae are spinal bones, and synovial relates to joints, not bones.
