The ulnar nerve is a nerve that in humans runs down the arm and forearm, and into the hand.
The ulnar nerve comes from the lower cord of the brachial plexus, and runs posterior to the humerus down the arm, going behind the medial epicondyle at the elbow. This part of the ulnar nerve is known as the funnybone for two reasons: because of its proximity to the humerus (and the similar word "humorous"), and because of the mild pain and tingling throughout the forearm associated with sudden compression of the nerve at this point.
It enters the anterior (front) side of the forearm, and runs alongside the ulna. It supplies one and a half muscles in the forearm: flexor carpi ulnaris (which flexes and adducts the wrist), and the medial two digits of flexor digitorum profundis (a muscle that flexes the fingers).

The "funny bone" is not an official anatomical term. It's technically not a bone at all- but rather the segment of the ulnar nerve that is located at the medial epicondyle of the elbow. (The ulnar nerve is the main nerve running down the arm, innervating the hand and fingers). When people hit their elbow at a certain angle/force, this portion of the ulnar nerve is compressed and produces an odd tingling sensation as a result.

There is no funny bone. The area in question, near the elbow, got its name because of the ulnar nerve. This nerve, unlike most nerves, actually runs outside our bodies skeletal protection. It is located very close to the surface of the skin and is very easy for this nerve to get hit. When struck it produces a strange feeling in our arm because it is a very large and sensitive nerve.
The reason this nerve's location has to do with us being able to rotate our forearm. The inner workings of the bones in our forearm allow us to grasp with great precision, the side affect however, is an uncomfortable location of the ulnar nerve.
If you have ever hit that area really hard, you would know that it is not really 'funny' at all. It actually hurts like hell.

The "funny bone" is actually a big lump of bone that projects from one
end of the ulna, one of the 2 bones in the forearm. You can feel the ulna
by puutting your hand out as if for a handshake and running your other hand
along the sharp bony lower margin of your forearm. You'll notice that the
ulna ends as a sharp point at your elbow. This point is called the
olecranon (o-LEK-ra-non). A very large nerve called the ulnar nerve runs
alongside it in its journey from the neck, the armpit, and the arm to the
forearm.

It is correctly called the Humerous bone. Located in your arm.
If you bang the tendons and the end of the bone -at the elbow, you get a strange tingling feeling.
