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

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

Answer: (C)

Two long bones make up the forearm: the radius and the ulna. The ulna sits on the side of the little finger, while the radius is on the thumb side. Of the two, the ulna is the longer bone, extending from the elbow to the wrist. The radius is the other forearm bone, but it is shorter. The other options aren’t forearm bones—scaphoid is a carpal bone in the wrist, and the ilium is part of the hip. So, the longer bone on the little-finger side is the ulna.
