you know that electric-shock like feeling that shoots through your arm when you incidentally hit a certain part of your elbow against a hard surface? pls someone should explain why that peculiar sensation happens on that part of the body.

It is due to funny bone effect.

The "funny bone" got its nickname because of that funny feeling you get after you hit it. But your 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.
