Even the slightest bulge of a weird bone can send a series of sneaky explosives that undulate from the tongue, with pain that undulates up and down the arm. So why is it so uncomfortable to hit this small area of the elbow?
The answer is very simple. It is the nerves, not the bones, that are struck.
To understand the cause of this discomfort, let’s review some important points of the human body. First, the weird bone is scientifically known as the ulnar nerve, the main nerve in the arm. It travels from the spine through the neck before meandering the humerus along the groove in the humerus (the bone that extends from the shoulders to the elbows). After passing through the elbow, the nerve passes through the ulna (the bone on the little finger side of the lower arm) and the radius (the bone on the thumb side of the lower arm) and reaches the wrist. The ulnar nerve is responsible for transmitting and restoring information from part of the fingertips to the brain. In particular, you can record the sensations of the little and ring fingers and control hand movements.
During most of the nerve journey, it is buffered by the bones, muscle And thick.. After passing the elbow, nerves pass through a small channel called the ulnar tunnel. Crossing this space, the radius and ulna pass by the hook of the elbow bone where the humerus meets.

So why is this area so sensitive?
Dr. Dominique King, a sports medicine doctor at the Cleveland Clinic’s Orthopedic and Rheumatology Institute, said: “When you hit a nerve against something hard, it presses on the nerve between the elbow bone and the hard surface you hit.”
When pressed against the ridge of the bone, the ulnar nerve experiences a rapid onset of so-called ulnar nerve entrapment, or a sharp electric shock from the arm to the hand, and strange numbness in the limbs.
“Nerves are the way we feel something in our bodies,” King told Live Science. “This is one big nerve that is really close to the skin and you are feeling complete nerve pain.”
Hitting a weird bone rarely causes damage. The pain usually subsides in a few minutes, but it’s enough to make you think about wearing an elbow guard all the time.
Beat the nerve
So if it’s nervous, why is it called funny? Bone?? The most rational explanation is in the anatomy of the arm. Remember: The large bone that extends from the shoulder to the elbow is called the humerus. get it? Humorous. Strange. If it’s a joke, it’s bad.
The second explanation lacks humor. This is based on the “strange” sensations one experiences when a nerve hits, suggesting that it was explained by a person with fairly high pain tolerance.
Other mammals have a similar composition, but the same problem rarely occurs. These animals are protected by more muscle mass around the sensitive nerves that accumulate around the different ways the animal moves. Padding adds a level of protection to this less interesting experience.
