YOUR AMAZING BODY

MOST people will have bashed their funny bone and felt that strange, tingling numbness radiate through the whole arm.

But the funny bone isn’t a bone at all – it’s the ulnar nerve, which runs from the neck to the hand. For most of its length it’s buried in muscles and ligaments, but at the elbow it runs through a channel called the cubital tunnel and comes close to the skin, making it vulnerable to knocks.

So when you hit it, you’re compressing the ulnar nerve against the underlying bone, resulting in that unique sensation that can be felt right down to the little finger.
