What is a fun bone?

The funny bone is not really a bone, but refers to the Ulnar nerve. The Ulnar nerve extends from hand to the shoulder and is exposed just above the elbow in the interior of the arm. Accidentally affecting this area can cause a considerable amount of pain or armor. In fact, for some, beating can have people who jump to limit the curse of words. The old proverb attached to this is that "hitting funny bone is not humerus." The sensitive and exposed part is only a small part of the Ulnar nerve. As the nerve runs along the inside of the arm, only the part in the elbow is a really funny bone section. The rest of the nerve is better protected.

In fact, this part is interesting from a scientific point of view, because it is the only exposed nerve in the human body. The bone, muscles and/or lines protect all other nerves, so a small intervention in the nerves generally does not cause pain. In this sense, unprotected, in this sense means that this part of the Ulnar nerve is covered with skin and perhaps a few fat cells. Is not covered or hidden between layersdeep tissues, ligaments, muscles or bones.

Not all people respond equally to the hit on funny bones. Some people describe the incident as a sense of "strange" or strange and slightly painful. Others tend to be more sensitive and feel great pain if they accidentally hit it on a hard object. Most people describe a certain degree of pain with armor.

So the funny bone is not really fun. It is an absolute incorrect name because anyone who hit the elbow can testify. Unless, of course, it does not take into account that it is "funny" in the sense that he is not at all bones.
