The autonomic nervous system regulates the main vital processes, for example, blood pressure and respiratory rate. This system works automatically (autonomously), that is, its operation does not depend on a person's desires. The autonomic nervous system consists of two main parts: sympathetic and parasympathetic.
After the autonomic nervous system receives information about the state of the body and the environment, it activates or slows down certain processes. Its sympathetic department is responsible for activation, and parasympathetic department is responsible for slowing down.
The autonomic nervous system controls the internal processes of the body, including:
Blood pressure.
Heart rate and respiratory rate.
Body temperature.
Digestion.
Metabolism (thus affecting body weight).
Balance of water and electrolytes (such as sodium and calcium).
Excretion of biological fluids(saliva, sweat, tears).
Urination.
Defecation.
Sexual response.
Many organs are controlled mainly by the sympathetic or parasympathetic department of the autonomic nervous system. Other organs are managed by both departments. For example, the sympathetic department increases blood pressure, and the parasympathetic lowers it. The joint work of both departments ensures the adaptation of the body to different situations. In the process of analyzing the indicators, it is necessary to take into account the lability of the system, comparing the indicators in one session when viewing a series of tests.
- increasing the tone of the parasympathetic nervous system
The parasympathetic department performs the following functions:
Control of body processes during normal situations.
In general, the parasympathetic department is responsible for preservation and restoration. It slows down the heart rate and lowers blood pressure. It stimulates the digestive tract to digest food and get rid of waste. The energy obtained from digested food accumulates or is used to build tissues. In case of predominance of the tone of parasympathetic nervous system, all processes in the body are inhibited or reduced, and a program correction is necessary.
- increasing the tone of the sympathetic nervous system
The sympathetic department performs the following functions:
Prepares the body for stressful or emergency situations — a “fight or flight” response.
For example, the sympathetic department increases the frequency and strength of heart contractions and facilitates breathing by expanding the airways. They force the body to release stored energy. Muscles tense up. The sympathetic part of the autonomic system makes the hands sweat, the pupils dilate and the hair stand on end. It slows down processes that are less important in emergency situations, such as digestion and urination.
If the tone of the sympathetic nervous system prevails, all processes in the body are elevated or tend to increase, a program correction is necessary.
- eutonia
Variant of normal. All processes in the work of the autonomic nervous system of the body are balanced with eutonia.
