Innervation definition. Motor innervation of muscle fibers of skeletal muscles. Substances that activate the transfer of excitation

Innervation(from Lat. in - in, inside and nerves) - supply of organs and tissues with nerves, which ensures their connection with the central nervous system (CNS).

Types of innervation

Distinguish between innervation afferent(sensitive) and efferent(motor). Signals about the state of the organ and the processes occurring in it are perceived by sensitive nerve endings (receptors) and are transmitted to the central nervous system through centripetal fibers. The centrifugal nerves transmit response signals that regulate the work of organs, due to which the central nervous system constantly monitors and changes the activity of organs and tissues in accordance with the needs of the body.

Role of the central nervous system

The role of the central nervous system in the regulation of the functions of different organs is not the same. In some organs (for example, in skeletal muscle or salivary gland), signals from the central nervous system determine their entire life activity; therefore, complete separation from the central nervous system - denervation- leads to organ atrophy. Some other organs (for example, heart, intestines) have the ability to function under the influence of impulses that arise in the organ itself (see automatism). In such cases, denervation does not lead to atrophy, but only limits to one degree or another the adaptive reactions, which, however, persist not only due to humoral regulation, but also due to the presence of the intraorgan nervous system. Renal nerve denervation is used for cardiovascular diseases... The denervation method is radiofrequency ablation of sympathetic renal nerves.

An excerpt characterizing Innervation

She kicked her dog off her knees and straightened the folds of her dress.
“Here is gratitude, here is gratitude to the people who sacrificed everything for him,” she said. - Perfectly! Very good! I don't need anything, prince.
- Yes, but you are not alone, you have sisters, - answered Prince Vasily.
But the princess did not listen to him.
- Yes, I knew this for a long time, but I forgot that, apart from baseness, deception, envy, intrigue, except ingratitude, the blackest ingratitude, I could not expect anything in this house ...
“Do you know or don’t know where this will is?” Prince Vasily asked with even more twitching of his cheeks than before.
- Yes, I was stupid, I still believed in people and loved them and sacrificed myself. And only those who are mean and disgusting succeed. I know whose intrigues it is.
The princess wanted to get up, but the prince held her hand. The princess looked like a man who was suddenly disillusioned with the whole human race; she glared at her interlocutor.
- There is still time, my friend. Do you remember, Katish, that all this happened by accident, in a moment of anger, illness, and then forgotten. It is our duty, my dear, to correct his mistake, to facilitate his last moments in order to prevent him from doing this injustice, not to let him die thinking that he made those people unhappy ...
“Those people who sacrificed everything for him,” the princess picked up, trying to get up again, but the prince did not let her in, “which he never knew how to appreciate. No, mon cousin, ”she added with a sigh,“ I will remember that in this world one cannot expect a reward, that in this world there is neither honor nor justice. In this world, one must be cunning and evil.
- Well, voyons, [listen,] calm down; I know your beautiful heart.
- No, I have an evil heart.
“I know your heart,” the prince repeated, “I appreciate your friendship and would like you to have the same opinion of me. Calm down and parlons raison, [let's talk really,] while there is time - maybe a day, maybe an hour; tell me everything you know about the will, and, most importantly, where it is: you must know. We will now take it and show it to the Count. He probably forgot about him and wants to destroy him. You understand that my only desire is to sacredly fulfill his will; then I just came here. I'm only here to help him and you.

INERVATION (from Lat. In - in, inside and nerves) is the connection of organs and tissues with the central nervous system with the help of nerves. Distinguish between afferent innervation, or centripetal (from organs and tissues to the central nervous system), and efferent, or centrifugal (from the central nervous system to organs and tissues).

Innervation

Innervation(from Lat. in - in, inside and nerves) - supply of organs and tissues with nerves, which ensures their connection with the central nervous system.

Examples of the use of the word innervation in the literature.

Innervation thyroid gland exercise sympathetic and parasympathetic nerves.

Since it was written before the discovery of the important role of estrogen and progesterone and even before understanding the role of acetylcholine, norepinephrine and epinephine, not to mention oxytocin and prostaglandins, one cannot help but be amazed at the ingenious conclusions about the importance of the value of a balanced innervation uterus.

There is a discrepancy here: the final common path is really narrow, and in order to get through to the executive organ, it is necessary to suppress, crush an opponent, an antagonist, but it was Ukhtomsky's idea that brought the excitation currents into a wide expanse of innumerable neurons in the brain, and for this alone it is necessary in principle new model antagonism as purely functional, a new model of reciprocal innervation as a principle of operation not only of effectors, but also of the reflex arc itself in its central part.

Let the individual data on this reciprocal innervation the work of muscles is even disputed, the matter is immediately transferred to the next instance: after all, very many organs of the body, the most diverse peripheral apparatuses, can perform opposite antagonistic works.

Russian physiologists, in turn, paid a lot of attention to reciprocal innervation antagonistic muscles, since they rightly saw this as one of the simple devices on which one can study the complex problem of the relationship between excitation and inhibition in the activity of the nervous system.

Sacral vegetative innervation limited to small, localized intervention of certain superior ganglionic fibers.

We need to know that innervation the muscles involved in this act can be influenced by emotional stress.

It is worth recalling that there is still a local innervation the uterus, which allows the longitudinal muscles to continue to contract, even if the autonomic innervation will be completely turned off by the predominant irritation of the sympathetic system.

This ensures innervation, with the help of which the prosthesis will be controlled in the future.

However, here he covered other, more high levels reciprocal innervation especially considering Sherrington's ideas.

Ukhtomsky on the issue of reciprocal innervation antagonists rises a step above Sherrington: not only in the sense of the level of the central nervous system, entrusting this work of simultaneous excitation and inhibition to the higher neurostructures of the brain, including the cortex, but also in the sense of replacing the anatomical antagonism of muscles with physiological antagonism of functions.

As in the question of reciprocal innervation, it is possible to trace the hierarchy from simpler mechanisms of inhibition and excitation, which are of an anatomical nature, to more complex physicochemical, to higher functional ones.

About this second half of the case in appearances innervation assumptions have been made for a long time.

Thus, the sensation found its way to the somatic innervation and thanks to this has brought to the fore its complex of associations.
