The membrane potential (MP) is the potential difference between naru w hydrochloric and inner surfaces of the membrane of the excitable cells in its rest conditions. On average, in cells of excitable tissues, MP reaches 50 –

Excitability as a special and zoned property of individual cells of an organism is caused by the presence of special properties in them, which are determined by the structure and function of their q and toplasmic membrane. Selective permeability of the membrane

Biochemical classification of neurons It based on chemical wasps on the singularity of neurotransmitters used by neurons in the synaptic transmission of nerve impulses. Many different groups of neurons are distinguished, in particular, cholinergic (mediator – acetylcholine), adrenergic (mediator

Functional classification of neurons divides them by the nature of the functions performed by them (according to their place in the reflex arc) into three types: the afferent (sensory), efferent (and mot-inflammatory) and associative. 1. Afferent neurons (synonyms – sensitive,

The brain consists of billions of nerve cells, or neurons. The neuron consists of three main parts: the body of the neuron (soma); dendrites are short processes that receive messages from other neurons; axon – a long single

Back in the XVIII century. Italian physician Luigi Galvani noticed that the prepared frog legs and short schayutsya in contact with the metal. He came to the conclusion that we w ci and nervous animal cells produce electricity. The Russian claim about Daubney study conducted

Modern methods of n allows one to see the structure of the human brain, without damaging it. The method of magnetic resonance imaging makes it possible to observe a series of consecutive “slices” of the brain on the screen of the monitor of

In theoretical studies of physics ogy human nervous system plays an important role the study of Central Noah s nervous system of animals. This area of ​​knowledge is called neurobiology. The structure of nerve cells, as well as the processes occurring in them,
