 * __WHAT HAPPENS TO MY ARM WHEN I HIT MY FUNNY BONE?__**

Answer the question below, append new answers to the top of this page. _ __Response 1:__ When you hit your funny bone you are actually hitting your ulnar nerve against your humerus (The bone that goes from your elbow to your shoulder). Your ulnar nerve is the nerve that tells your brain if anything is happening to your fourth and fifth fingers. Bumping your ulnar nerve doesn't do any damage to it so nothing is going wrong when you hit it even though it might feel like it. The ulnar nerve is the largest unprotected nerve in your body so that's why you don't have any other funny bones because there aren't very many big unprotected nerves in your body so you don't notice if you hit another unprotected nerve. So when you hit your funny bone, nothing really happens to your arm, it's just one nerve getting bumped.
