Mostly only funny when other people hit it. It isn’t even a bone you’ve hit. It’s actually a nerve. Specifically, the ulnar nerve. This nerve, one of the three main nerves in the arm, runs from the neck area and extends to the hand. The ulnar nerve innervates muscles of the forearm, hand and two fingers (the ring and pinky fingers). It is believed to have been named the “funny bone,” because the nerve corresponds to the humerus bone (which sounds like humorous, as in funny). It is also speculated that the term comes from the “funny” feeling of hitting it. How can a gentle tap cause such a severe reaction? At its most vulnerable spot, the ulnar nerve passes through a channel called the cubital tunnel. It is there that protection is limited to only a thin coating of skin and minimal fat. Typically, when you hit the ulnar nerve, you give it 30 seconds, shake your arm around and that fleetingly pain goes away. But, what happens when it’s more than a temporary feeling? Prolonged pain, numbness or tingling can be caused by an injury or overuse. In rare incidents, maybe a tumor. It is the result of nerve irritation, inflammation or ulnar nerve entrapment. https://neurosurgerycnj.com/the-funny-bone-aka-the-ulnar-nerve-is-no-laughing-matter/ My question is....when do you typically knock this? It shouldn't be common....as the nerve is hidden pretty well. I've done it three times in the past year getting out of my car. It's an SUV now....and there is not as much space in my garage with this. Seems to be the result of turning around after I get out and pulling the door in. Ouch. I'd guess that people with nightstands higher than their beds run into this often as well. What say you?
