The value of the nervous system in the human body is enormous. After all, it is responsible for the relationship between each organ, organ systems and the functioning of the human body. The activity of the nervous system is caused by the following:
- Establishing and establishing the relationship between the external world (social and ecological environment) and the body.
- Anatomic penetration into every organ and tissue.
- Coordination of each metabolic process that takes place inside the body.
- Managing the activities of apparatuses and systems of organs, integrating them into one.
The importance of the human nervous system
In order to perceive internal and external stimuli, the nervous system has sensory structures in the analyzers. These structures include certain devices capable of perceiving information:
- Proprioceptors. They collect all the information concerning the condition of muscles, bones, fascia, joints, the presence of fiber.
- Exteroreceptors. They are located in human skin, sensory organs, mucous membranes. Are able to perceive the irritating factors obtained from the surrounding environment.
- Interreceptors. Are located in tissues and internal organs. Responsible for the perception of biochemical changes obtained from the external environment.
The main significance and functions of the nervous system
It is important to note that with the help of the nervous system, perception, analysis of information about irritants from the external world and internal organs is carried out. She is also responsible for responding to these irritations.
The human organism, the fineness of its adaptation to changes in the surrounding world, is realized, primarily due to the interaction of humoral mechanisms and nervous ones.
The main functions include:
- The definition of mental health and human activities, which are the basis of his social life.
- Regulation of normal vital functions of organs, their systems, tissues.
- Integration of the organism, its integration into a single whole.
- Maintaining the relationship of the whole organism with the environment. In the case of changing environmental conditions, the nervous system makes adjustments to these conditions.
In order to accurately understand the importance of the nervous system, it is necessary to understand the meaning and main functions of the central nervous system and peripheral.
The importance of the central nervous system
It is the main part of the nervous system of both humans and animals. Its main function is the realization of a different level of complexity of reactions called reflexes.
Thanks to the activity of the CNS, the brain is able to consciously reflect changes in the external conscious world. Its significance lies in the fact that it regulates all kinds of reflexes, is capable of perceiving stimuli received both from internal organs and from the outside world.
The importance of the peripheral nervous system
PNS connects the CNS with limbs and organs. Its neurons are located far beyond the central nervous system - the spinal cord and the brain.
It is not protected by bones, which can lead to mechanical damage or harmful toxins.
Due to the proper functioning of the PNC, the coordination of body movements is consistent. This system is responsible for conscious control of the actions of the whole organism. Responsible for responding to stressful situations and danger. Increases heart rate. In case of excitement, increases the level of adrenaline.
It is important to remember that one should always take care of one's health. After all, when a person leads a healthy lifestyle, adheres to the correct regime of the day, he does not load his body in any way, and thus remains healthy.
