Nosotros're all familiar with that incredibly uncomfortable — and ofttimes painful — tingling feeling that comes along with hitting your funny bone. And nosotros all know information technology'due south anything but funny. Only what exactly is causing this foreign and unwelcomed feeling? Here'due south everything you lot need to know near your funny os and why it hurts so much to hit it.
What is your funny os?
Funnily enough, your funny bone isn't a os at all. It'southward actually the ulnar nervus, which extends from your spine, passing behind the elbow joint and going all the way downwardly to your pinky and band fingers. This nerve is responsible for giving sensation to your forearm also every bit your fourth and fifth fingers and helps stimulate movement in your mitt and wrist.
Why does information technology hurt when you hit it?
There's a point where the ulnar nerve curves around the elbow articulation and is substantially wedged between bone and skin. Specifically, when the nerve reaches the elbow it goes through the cubital tunnel. This is a tunnel of tissue on the inside of the elbow under a bony portion of the humerus (your upper arm bone) called the medial epicondyle.
At this specific point, the nerve is not protected past any musculus. The awareness you feel when you lot hitting this precise spot is actually the nervus being pinched and compressed. Hitting your funny bone happens when your elbow is bent rather than extended considering the former opens up this small and sensitive area. This temporarily stops the nerve's connection to the brain and results in that familiar feeling of hurting and numbness. The pain follows the nervus'southward path and shoots down into your arm and fingers. Considering the nerve is also responsible for some hand and wrist movements, it tin can have a few minutes to become these movements back after whacking your funny os.
And while striking your funny bone is something y'all can usually laugh about in one case the pain subsides, in some instances the pain and discomfort is ongoing. Cubital tunnel syndrome is a condition where the ulnar nerve is stretched or pinched easily and frequently, sometimes for extended periods of time. This condition can develop from regular movements where your elbow is bent, like spending large parts of the twenty-four hour period making phone calls and holding your phone to your ear. But it can likewise be the result of aberrant bone growth in the elbow or from intense physical activeness that increases pressure level on the nervus (for case, baseball pitchers often have cubital tunnel syndrome).
And while the symptoms tin exist similar to those of hitting your funny os — although they persist for longer and occur more than frequently — some symptoms are more than extreme, such as a decreased gripping-ability and difficulty controlling fingers for precise tasks.
Why is information technology called the funny bone?
It'south not entirely articulate how the funny bone got its name, because it isn't a bone at all. But there seems to be two main competing theories. The outset, is that information technology's based on the "funny feeling" you get when you striking your elbow in that not-and so-sweet spot. The second, is that information technology'southward a play on words because the ulnar nerve runs forth the upper arm os called the humerus (sounds like "humorous") that is between your elbow and shoulder.
Despite the uncertainty around its name, one thing'south for sure: hitting your funny bone is really non so funny.
