Your funny bone

The funny bone is actually not a bone at all—it’s just a playful name for your ulnar nerve, a huge nerve that runs on the back of your elbow. This nerve sits next to the bone in your upper arm called the humerus. (That’s where the “funny” name comes from.) Since there’s barely any padding to protect the ulnar, the nerves fire off more easily when the area is hit. “Nerves are composed of different fibers, some of which respond to touch, and some of which respond to pain,” says Dr. Spiel. You guessed it: Your brain interprets a funny bone blow as intense pain. And because the nerve also sends signals in the other direction, towards your hand, you might feel pain all the way through to your fingers, too, Dr. Spiel explains.

Bohdan, ty jeden nerd do anatómie... Nielen, že sa mu vŕtaš v kĺbe, ty mu do slova a do písmena brnkáš na nervy.
