The human body - a very complex system. For successful operation it is necessary to a strict and wise leadership. Any area of ​​the body is under the supervision of of the brain. And help him in the neurons (nerve cells). neuronal processes form the nerves, and these in turn:

1. Transmit information from all organs and parts of the body to the brain.
2. Transmit commands from the brain.

When you are a long time in an awkward position (eg, crushing his leg), the connection of the leg to the brain is temporarily lost, because squeezed themselves nerves and blood vessels that bring oxygen and glucose and ensure the existence of legs fabrics (including those the nerves). And this is where the fun begins.

The brain sends a signal: "Hey, what's up with your leg?" - but with communication problems. Neurons are thinking, "What's wrong with the brain, it can not be heard... I think we do not have enough oxygen. Panic!!! Panic!!! "and start sending random signals.

Brain: "Interference due, but it seems that the leg is missing. Leg nemey! Wait, no! Leg, cold! Release the goose! What is happening there at all? "

At this stage, a person usually feels uncomfortable and changes the position. Of compression is no more, the blood circulation is restored, the brain again liaise with peripheral neurons and chills disappear in a few minutes.
