Funny
Bone (Ulnar Nerve)
The ulnar nerve is trapped between the bone and the overlying
skin at this point. This is commonly referred to as bumping one's "funny bone." This name
is thought to be a pun, based on the sound resemblance between the name of the bone of the upper arm, the "humorous" and the word "humorous".
Alternatively, according to the OED it may refer to "the peculiar sensation experienced when it is struck". In human anatomy, the ulnar nerve is a nerve which runs near the ulna bone. The ulnar collateral ligament of elbow joint is in relation with the ulnar nerve. The nerve is the largest unprotected nerve in the human body (meaning, unprotected by muscle or bone), so injury is common. This nerve is directly connected to the little finger, and the adjacent half of the ring finger, supplying the palmer side of these fingers, including both front and back of the tips, perhaps as far back as the fingernail beds. Funny bone isn't actually a bone at all. Running down the inside part of your elbow is a nerve called the ulnar nerve. The ulnar nerve lets your brain know about feelings in your fourth and fifth fingers. It's also one of the nerves that controls some movement of your hand.

You get that funny feeling when
the ulnar nerve is bumped against the humorous, the long bone that starts at your elbow
and goes up to your shoulder. Tapping your funny bone doesn't do any damage to
your elbow, arm, or ulnar nerve. But it sure feels strange.
