That’s what I discovered out indigenous my girlfriend Janessa Graves. She’s a researcher in ~ Washington State college who knows a lot around the person body and also studies injuries, like concussions in children.
Most nerves in the human body usually have actually some kind of protection. Regularly they space cushioned by muscle or bone. Yet the ulnar nerve is a small different. Component of her ulnar nerve travels v a channel in her arm called the cubital tunnel. This leaves component of the nerve roughly your elbow a bit much more exposed. That only safeguarded by a little bit of skin and fat.
When us hit our elbow simply right on a corner or tough surface, the nerve it s okay squished, or compressed.
“This compression creates a painful, shocking, burn or study abroad sensation the is nice unique,” tombs said. “It shoots all the way down come the tips of ours fingers, i m sorry is where the nerve ends.”
If you perform hit your ulnar nerve, you’ll most likely only feel those sensations for around 30 seconds or so. Also though it deserve to be a little painful, it no usually do much damages to the nerve. Graves adds the sometimes human being do hit their funny bone and that feeling doesn’t go away, so they need to see a medical professional to number out specifically what could be going on.
Either way, it no seem like lot of a laughing issue when girlfriend hit her funny bone. That made me wonder whereby it obtained its name. Tombs said there room a few ideas about it.
One idea is the it’s due to the fact that the ulnar nerve is next to a bone referred to as the humerus bone, which runs from her shoulder come the elbow. Some world think the funny bone acquired its name since humerus sounds prefer humorous—it’s a homonym, or a word the sounds like another word but has a different spelling.
