Interesting Facts about Bones

What is your funny bone?

Your “funny bone” is not a bone at all, but a large nerve, which is named the ulnar nerve. It passes very close behind the arm bone at the inner side of the elbow.

It is easily irritated when you bump it, causing a sharp tingling or numbness down the arm and into the hand. Ouch!
