What is an autonomous nervous system?

Most people rarely aware of this, but the autonomous nervous system of the body (ANS) regulates a lot of what they do every day, to a large extent beyond their conscious control. It is part of the peripheral nervous system and regulates many of our most basic functions such as heart rhythm and breathing. This system can be divided into three parts: sympathetic, parasympathetic and enteric nervous system.

The sympathetic part of the system helps the body to use energy and is associated with the reaction of "fighting or flight". If one sees an animal they are afraid of, he could run the opposite or carefully around him. The fact that an increased increase in heart rhythm, dry mouth and adrenaline is the result of a sympathetic part of the autonomic nervous system at work.

The parasympathetic nervous system is on the other side of relaxation. It starts the digestive process, slows down the heart rhythm and helps the body to save energy. Therefore, most fitness experts wait at least an hour after eating for any intensive physical exercise. BodyIt needs energy to digest food even for strenuous exercise. A nice walk immediately after dinner can be fine, but one should have an hour or two for an hour or two.

Even if necessary, such modest functions as salivation, sweating and expansion pupils in response to light are the tasks of the autonomous nervous system. ANS also regulates how much blood vessels dilate and control blood pressure.

The

Enteric system is that the weight of nerves and nerve fibers in the gastrointestinal system and helps to regulate digestion and excretion. This system is why one knows that his bladder is full. The nerves indicate that "full" feels, tells the person that he needs to use the toilet.

"full" feeling that comes after a good food also an enteric system that performs its work. It also tells the stomach to process foods into amino acids. Loss of control of the body when they are afraid is olda way to help the body prepare for a flight. A person can run faster on an empty stomach.

The autonomous nervous system study reaps large rewards in the medical field. Scientists learn ways to fight disease and help improve the quality of life through researching this complex system.
