The main types of the human nervous system

The nervous system in combination with the endocrine system ensures the regulation of the body's functions, controls all the processes occurring in it. It consists of the central sections, to which the head and spinal cord, and the peripheral part - nerve fibers and nodes.

The Russian scientist I. Pavlov classified the variants of the nervous system in people depending on the functional characteristics: the strength and displacement of the processes of excitation and inhibition, and also their ability to be in equilibrium. Expressed these properties in a particular person the speed of reactions, the speed of decision-making, the severity of emotions.

What are the types of the human nervous system

There are four of them and they are interestingly correlated with the types of human temperament, highlighted by Hippocrates. Pavlov argued that the types of the nervous system Largely depend only on innate qualities and change little under the influence of the environment. Now scientists think differently and say that in addition to hereditary factors, the social environment and upbringing also play a big role.

Consider the types of the nervous system in more detail. First of all, they can be divided into two large categories - strong and weak. In this case, the first group has a subdivision into mobile and inert, or immovable.

Strong types of the nervous system:

Movable unbalanced. It is characterized by high strength of the nervous processes, excitation in the nervous system of such a person predominates over inhibition. His personal qualities are as follows: he has a lot of vital energy, but he is quick-tempered, difficult to hold back, highly emotional.

Movable counterbalanced. The strength of the processes is high without the predominance of one over the other. The holder of such characteristics of the nervous system is active, lively, adapts well and successfully resists life problems without much damage to the psyche.

As we see, mobile types of the nervous system are those whose functional qualities are the possibility of a rapid transition from excitation to inhibition and in the opposite direction. Owners of them can quickly adapt to changing environmental conditions.

The inert counterbalanced. Nervous processes are strong and in balance, but the change in excitation by inhibition and vice versa is slowed down. A person with this type is not very emotional, can not respond quickly to changes in conditions. However, it is resistant to prolonged exhausting influences of unfavorable factors.

The last type of nervous system - melancholic - is referred to the weak. The nervous system is characterized by a predominance of inhibition, a passive person is expressed in the person, low working capacity and emotionality. Psychic is not very resistant to negative environmental factors.

The great ancient physician distinguished four variants of temperament: they are nothing more than an external manifestation of the type of functioning of the nervous system. They are presented in the order corresponding to the types considered above:

• Choleric (first),
• Sanguine (second),
• Phlegmatic (third),
• Melancholy (the fourth).
