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

Explanation:
Two long bones form the forearm: the ulna and the radius. The ulna sits on the side of the little finger (medial in the anatomical position) and is the longer of the two forearm bones. The radius lies on the opposite side (thumb side) and is typically shorter. This arrangement explains why the bone on the pinky side is described as longer. The humerus is the upper arm bone, and the fibula is a leg bone, so they aren’t the forearm bones being asked about.
