Part of the Parasympathetic Nervous System

The human body is made up of many complex systems that work together to support life. One of these systems is the autonomic nervous system, which controls the functions of internal organs and tissues that do not depend on our will. The autonomic nervous system is divided into two parts: sympathetic and parasympathetic. In this article we will look at the parasympathetic part of the autonomic nervous system.

The centers of the parasympathetic nervous system are located in the midbrain, medulla oblongata and pons, as well as in the sacral spinal cord. From here arise fibers that innervate blood vessels, glands and most internal organs. The fibers of the parasympathetic nervous system emerge from the spinal cord as part of the III, VII, IX and X pairs of cranial and II-IV sacral spinal nerves.

The functions of the parasympathetic nervous system include accelerating intestinal motility, decreasing heart rate, dilating the bronchi, increasing the secretion of glands and salivary glands, constricting the pupils and so on. In addition, the parasympathetic nervous system plays an important role in the digestion process, as it stimulates the secretion of gastric juice and insulin.

The activity of the parasympathetic nervous system is constantly balanced by the activity of the sympathetic part of the autonomic nervous system, which, on the contrary, maintains the body in a state of wakefulness and combating stress. The sympathetic nervous system increases the heart rate, dilates the bronchi, increases sweating, increases blood pressure, and so on.

An imbalance between the parasympathetic and sympathetic nervous systems can lead to various diseases. For example, excess activity of the sympathetic nervous system can cause hypertension, and excess activity of the parasympathetic nervous system can cause bradycardia.

In conclusion, the parasympathetic nervous system plays an important role in regulating internal organs and tissues to ensure the harmonious functioning of the body. It is important to remember that balance between the parasympathetic and sympathetic nervous systems is key to maintaining health and well-being.

Part of the Parasympathetic Nervous System:

One of the two parts of the autonomic nervous system. The centers are located in the midbrain, medulla oblongata, pons and sacral parts of the spinal cord. Fibers originate in the III, VII, IX, X cranial and 2-4 sacral spinal nerves.

The parasympathetic nervous system controls the activity of internal organs and glands. Its work is balanced with the work of the sympathetic nervous system, which performs opposite functions in the body.

The activity of the parasympathetic system ensures the normal functioning of internal organs such as the heart, lungs, stomach and intestines, and also regulates the release of various hormones and enzymes. It is also responsible for restoring and maintaining homeostasis in the body.

Part of the parasympathetic nervous system: what its system is for. Since ancient times, mythical creatures (for example, Griffins) have carried a huge semantic load: primarily magical. Conquering the gods and heavens is the sacred goal of every brave warrior! The embodiment of this kind of thoughts is not always found in reality, and a person who stands face to face with ancient Greek images is unlikely to lead a cunning company in a rush. However, each type of ancient culture can serve as an example with a clearly expressed concept, which is partly related to all psychological operations. It was the same with health.

What is known about the parasympathetic nervous system? There are two main parts of the autonomic or autonomic nervous system in the context of the **somatic** part of the body, which we divide into two, called **Parasympathetic Nerve (PNS) 20% and Sympathetic Nerve (SNS)****80%** regarding response effects on the body system. The sympathetic part of the system activates muscles and brings us to action in times of extreme stress and fear. At the same time, pressure and heart rate increase, which increases blood circulation and oxygen flows to all vital organs. This mode allows you to work well in extreme situations, reacting with a sudden decision in order to survive. In addition, when the sympathetic nervous system is activated, increased sweating occurs, which helps the body get rid of excess heat and thirst. However, under prolonged stress, this type of response is not optimal. In an attempt to adapt to living conditions and the environment, the system begins to work **with double load**. The result will not be long in coming - an unexpected reduction in the amount of vitality and deterioration in health. Therefore, parasympathy is the reverse form of sympathy. The parasympathetic portion of the autonomic nervous system activates the gastrointestinal tract and other organs of the digestive system while helping to restore energy by absorbing water and nutrients. At the same time, the effect of adrenaline, which takes part in stimulating the activity of the cardiovascular system and other organs, is reduced - this leads to relaxation and restoration of the body. Also, thanks to the activation of the body's taste buds, the loss of essential nutrients is replenished and the immune system is strengthened. This is very important, because in order to protect yourself from the insidious diseases of our time, it is important to pay attention to the quality of food absorption and its value.
