If your elbow is cut by something, you will die, but why is it not so painful when something hits another part of your hand? Medical experts have found the answer to this question.

According to the science journal Live Science, an injury to the elbow hurts more because there are nerves, not bone, and that's why this area is also called the 'funny bone'. The funny bone sends out electric shock waves from the entire arm to the tongue if it is touched by even the slightest object.

Regarding this, Dr. Dominic King of the Cleveland Orthopedic Institute says that to understand this, one has to look at the tissue system in the human body. In scientific terms, the funny bone is known as the Ulner nerve, which is the main nerve of the arm. This vein travels from the spine to the neck through the crease between the two long bones in the arm from the elbow to the shoulder. This Ulner nerve is also responsible for the exchange of information from the tip of the finger to the brain, thanks to this nerve we can feel something by touching it.

Internal structure of the elbow and the ulnar nerve

As the nerve travels through the space in your arm, the friction between the bone in your arm and the hard surface that hits it puts pressure on the nerve, causing an electric shock-like pain. This nerve located in the muscle and fat layers in the elbow sends pain signals to the entire arm and brain when injured, causing the feeling of pain to tingle the entire body.
