What's Funny About a Funny Bone? - as part of the news and politics series by GeoBeats. While the phrase 'funny bone' is commonly used, it's actually a misnomer. When even a gentle hit to our elbow can send shooting pain and tingling down our arm, we don't find anything funny about it. Also, the body part responsible for this sensation is not even a bone. It's a nerve called the ulnar nerve. That ulnar nerve, which goes from the neck to our hands, dictates feelings in our ring and little finger along with controlling some muscles in the forearm. At the elbow joint, the nerve is very close to the surface of the skin and is not protected by a muscle or a bone. So when you hit that elbow, you are hitting your ulnar nerve. Noone knows for sure how the name 'funny bone' came about? One possible source for the name could be related to that 'tingling' or 'funny' feeling. Another, more plausible theory is that the ulnar nerve gets bumped against the humerus bone which goes from our elbows to shoulders and that's how the name was derived. Even if the phrase 'funny bone' doesn't accurately describe what's going on, it is still a great name and we should stick with it. 'Ah..I hit by ulnar nerve" just doesn't have the same catchy effect.
