Which bone is the longer of the two forearm bones, on the side of the little finger?

• A. Radius
• B. Ulna
• C. Scaphoid
• D. Metacarpal

Answer: (B)

In the forearm, the two long bones are the radius and the ulna. The bone on the pinky finger side (medial side in anatomical position) is the ulna, and it is the longer of the two forearm bones. The radius sits on the thumb side (lateral). The scaphoid is a wrist bone, and the metacarpals are in the hand, so they aren’t forearm bones. So the longer forearm bone on the little finger side is the ulna.
