Question:
Why do they call it a funny bone, and why does your arm go numb when you hit it?
Answers:
The medical term for the arm bone humerus is the origin of the term funny bone but really when you "hit" your funny bone you are hitting your ulnar nerve as it passes through your elbow down to your hand. That is why the numbness.
