 Which part of the human body is commonly referred to as the "funny bone"? Answer

The part of the human body commonly referred to as the "funny bone" is not a bone at all, but rather a nerve known as the ulnar nerve. This nerve travels from the shoulder down to the hand, and at the elbow, it passes through a shallow groove behind the medial epicondyle of the humerus – the bony bump on the inside of your elbow. In this location, the ulnar nerve is relatively exposed and has only a thin layer of skin and connective tissue protecting it.

The peculiar and often momentarily painful sensation experienced when you strike your "funny bone" occurs because you are directly hitting and compressing the ulnar nerve against the humerus bone. This compression sends a shock-like signal along the nerve, resulting in a tingling, prickly, or sometimes sharp pain that radiates down the forearm into the ring and pinky fingers, which are innervated by the ulnar nerve. The term "funny bone" is likely a pun on the word "humerus," the name of the bone it rests against, or perhaps it's a slightly ironic description of the not-always-pleasant feeling it produces.
