The funny bone extends from the shoulder joint to the elbow, and as we all know from experience, getting hit on this bone is anything but funny. When we accidentally bump our elbow against a hard surface, we get an uncomfortable tingling sensation. We feel a sting shooting from the forearm to the little finger. Then why is the bone called “funny bone”? Simple. The medical term for this bone is “humerus”; it is pronounced the same way as “humorous”! Hence the name “funny bone”. Are you amused?
