16.Instead of the sensation simply activating peripheral receptors that send electrical signals along your ulnar nerve, the nerve's fibers are stimulated directly.
17.Sensory receptors in your pinky finger's tissues register that unfortunate information and send electrical impulses up the ulnar nerve, which are then processed in your central nervous system.
18.Similarly, the ulnar nerve supplies the hypothenar muscles which control the little finger, the interossei muscles which abduct and adduct the fingers, meaning to spread or bring them together.
