Excitation of the vagus nerve. Stimulation of the nervus vagus: calmness in stressful situations. Folk methods of treating pathology

Vagus fibers conduct impulses to organs in the head region (they innervate the larynx, palate and middle ear region), as well as the chest and abdominal cavities.

The main functions of the vagus nerve are associated with the work of the parasympathetic nervous system. What does it mean? - In the human nervous system there are a pair of opposites - the sympathetic and parasympathetic nervous system.

sympathetic- associated with the activation of the body, vigorous activity, aimed at increasing the speed of reactions, intensive production of hormones, prepares for running, for fighting.

Parasympathetic nervous system - prepares the body for relaxation, recuperation, digestion of food, sleep, sex and other activities associated with pleasure. Thus, the vagus nerve partly regulates the mood and sleep of a person.

With chronic overexcitation of the nervous system, muscle hypertonicity and similar conditions, dysfunction of the vagus nerve can be assumed.

Where is the vagus nerve located? - You can feel it yourself directly in the hole under the earlobe.

Coming out of the jugular foramen of the brain, the vagus descends along the side of the neck as part of the neurovascular bundle along with the carotid artery and internal jugular vein. Passes near the trachea and pharynx, innervating them. Further, the vagus passes into the chest cavity, its right branch goes next to the right subclavian artery, and the left one - in front of the aortic arch. Both branches approach the lower part of the esophagus, passing from it in front and behind, and regulate its functions. Further, through the opening of the diaphragm, both nerve fibers enter the abdominal cavity. They innervate the stomach. Then part of the fibers goes to the liver, part - to the celiac (or solar) plexus. From the celiac plexus, the fibers are suitable for all organs of the abdominal cavity, except for the lower sections of the large intestine and the organs of the small pelvis.

The vagus nerve in its composition has fibers responsible for motor skills and sensory (mixed type), but all its activity is still associated with the autonomic nervous system - from the word "vegetable" - "vegetable" (that which cannot be controlled by consciousness) - as opposed to somatic nervous system - from the word "soma" - "body" (we can consciously control the movement of muscles).

Dysfunction symptoms

Since the vagus nerve innervates the larynx, its damage leads to problems with speech and uncomfortable swallowing, to the loss of the gag reflex. Disruption of the gastrointestinal tract is also one of the manifestations of vagus dysfunction, manifested in loss of appetite, there may be a feeling of satiety after eating a small amount of food.

Reasons for the defeat

One of the causes of damage to the vagus nerve is diabetes mellitus. The mechanism that destroys nerve fibers is not fully understood. The causes of damage and irritation of the vagus nerve can also be body injuries received, for example, during a car accident and others when a pinched nerve has occurred. Surgery can also affect how the nerve works.

Vagus Nerve Exercises

Preparation:

• Sit upright in a chair with your hands folded in your lap
• Place both feet on the floor and take a deep breath

Neck area

• Stretch your head as far as possible with the top of your head up and turn it to the left and right. Repeat this movement several times.

Lower jaw area

• Move your lower jaw, slowly opening and closing your mouth, moving it from side to side, back and forth. Feel the jaw muscles, the tension of which can cause pain. Do this exercise until you feel slight fatigue in your jaw.

Eyes

• Open and close your eyes. Look in different directions without moving your head - left and right, up and down. Alternately open your eyes wide and squint.

Facial muscles

• Remember your childhood, and for a few minutes, "make faces", trying to use as many facial muscles as possible.

Middle ear

• Listen. Hear ambient sounds in the background, such as the creaking of chairs, the sound of a passing car's tires, the chirping of birds, the sound of an elevator, the sound of a computer running, or the sound of an air conditioner or fan.

Throat

• First make a few coughing movements (as if something is in the trachea), and then swallow the saliva.

Larynx

• Start developing your voice, for example, you can hiss like a snake, or roar like a lion. The main thing is that these sounds lead to tension in the muscles of the larynx.
• Feel the vibration in the larynx, the vibration sound should reach the diaphragm and disperse throughout the abdomen.

Listen to how you feel, especially the feeling in your chest. Pay attention to every, no matter how small, positive change. With the daily implementation of this complex, you will increase the tone of the vagus nerve and the whole body, revive the internal energy!

What is the vagus nerve? The first question that this phrase causes for many is why is it still wandering?

The human brain is connected to 12 pairs of nerves, which in turn are called cranial nerves. The 1st, 2nd and 8th pairs of nerves are responsible for distinguishing between light, smell and sound. The 3rd, 4th and 6th pair are responsible for controlling the movements of the eyeball and pupil. The 5th and 7th pair are responsible for controlling facial expressions, but the 12th pair is responsible for the language. The 9th, 10th and 11th pair of nerves are responsible for the stomach, heart and lungs, as well as other internal organs (and so on to the inside of the mouth). The tenth pair of nerves is called the "vagus nerve", it is connected, like all other pairs of nerves, with the entire cranial parasympathetic system, and has an effect on almost all parasympathetic. In addition, by transmitting signals through them, it excites almost every internal human organ. Its name comes from the Latin word "vagus" - wandering, because it seems to wander throughout the human body. Its branches are located in the head, cervical, thoracic and abdominal regions of the human body.

The vagus nerve influences many human reflex actions such as swallowing, coughing, vomiting, filling and emptying the stomach. It also regulates many processes: heartbeat and breathing. The vagus nerve in the human body forms. According to its functions, this nerve is called mixed, since it includes both motor fibers and sensory and autonomic fibers.

The vagus nerve can be prone to the following diseases:

• angioneurosis is a disease in which there is a violation of the function of blood vessels as a result of innervation. This series includes the following diseases: Raynaud's disease, migraine, Meniere's disease, erythromelalgia;
• neurasthenia is a neurosis that is characterized by increased excitability with irritability, exhaustion of the body, weakness and dysfunction of the autonomic nervous system.

Migraine is a paroxysmal headache that has an independent

Meniere's disease is a lesion of the segmental apparatus of the brain and peripheral parts of a person, manifested by bouts of dizziness and simultaneous hearing loss.

Raynaud's disease is a lesion of the segmental apparatus of the brain and the peripheral parts of the nervous autonomic system of a person, the signs of this disease are blanching or cyanosis of the fingers, as well as parts of the face during cooling, emotional and other irritations, and symmetry of the lesions.

How to keep the vagus nerve healthy? The treatment of his pathologies is difficult, remember this. Diseases in this area are difficult to treat and seriously complicate life. It is necessary to consult a doctor in time for any warning signs and unpleasant symptoms, follow the instructions and just be less nervous.

In severe cases, electrical stimulation is often prescribed, sometimes even surgical methods are used. The previously used method of "alcoholization" (the introduction of ethyl alcohol in the form of injections) is becoming less common. Unfortunately, treatment with folk remedies is ineffective or gives little result. Therefore, do not get carried away with it - you can lose precious time that you can spend on a full examination and treatment. Modern diagnostic methods with great accuracy allow you to identify the disease and help in the appointment of effective procedures. Do not neglect the advice of a doctor - vagus nerve diseases are dangerous for their complications, sometimes very serious.
Now, knowing a little more about the vagus nerve, you can always take care of its "health"!

Irritation of the vagus (Goering, Lyois) or sympathetic nerve Rothberger (Rothberger) and Vinterberg caused in the experiment the appearance of extrasystoles and other rhythm disturbances, but only under certain conditions and not always, for example, in rabbits - only with simultaneous clamping of the aorta or when causing shortness of breath, in dogs - with the help of the preliminary application of a number of chemical agents, such as calcium, strontium, barium, aconitine, chloroform, etc.

Often, extrasystoles appear when the vagus nerve is stimulated, without being accompanied by any slowing of the rhythm. This confirms that the influence of the vagus nerve can contribute to the appearance of extrasystoles not only by slowing down the rhythm, but also by activating the hidden focus of ectopic excitation, which is unable to manifest itself without vagal stimulation. At the same time, excitation of the higher centers of the vagus nerve has an inhibitory effect on the function of the ectopic centers. Concerning a sympathetic nerve there are also conflicting experimental data. Its irritation in some cases enhances the ectopic rhythm, in others it eliminates it (Sherf, 1953).

The occurrence of extrasystoles under the influence of extracardiac nerves cannot be explained by the isolated action of the cardiac branches of either the vagus or sympathetic nerve. The correctness of the heart rhythm is ensured by the combined action of all cardiac nerves, and rhythm disturbance indicates a change in their coordination.

Treatment of sinus tachycardia

Treatment should be primarily aimed at eliminating the cause that caused sinus tachycardia (rheumatic heart disease, neurosis, thyrotoxicosis, chronic infections).

Arrhythmia and its causes

An arrhythmia is any disorder associated with a violation of the regularity or frequency of the heart rhythm and with the electrical conduction of the heart.

The term arrhythmia combines disorders, diverse in their mechanism of appearance and symptoms, associated with the origin and flow of electrical impulses in the heart. They are formed due to disorders associated with the cardiac conduction system, which should provide periodic regular contractions of the myocardium, or rather the correct sinus rhythm. Arrhythmia can cause a serious disruption in the functioning of the heart or in the functioning of other organs, or become an independent complication that provokes the occurrence of severe pathologies. According to statistics, about 15% of cases of heart rhythm disturbances cause death. Arrhythmology is a branch of cardiology that studies the diagnosis of arrhythmias of various origins.

The correct rhythmic heartbeat occurs due to the muscle fibers in the myocardium, which make up the conduction system of the human heart. The conducting system sets a certain rhythm, sequence and frequency of atrial and ventricular contractions. Improper functioning of this system causes the development of arrhythmias and conduction disorders. In this case, the clear activity of the ventricles and atria is disturbed.

According to the causes and manifestations of arrhythmia, it can be divided into two groups:

• arrhythmias associated with cardiac pathology - organic;
• arrhythmias not associated with cardiac pathologies - inorganic.

The main companions of cardiac abnormalities and complications after heart surgery are forms of organic arrhythmias.

The basis for the development of organic arrhythmia is damage to the heart muscle, which complicates the correct entry of an electrical impulse from the heart to its departments. Sometimes damage reaches the sinus node, and this is the basis of the rhythm.

Sympathetic arrhythmias of neurogenic origin develop due to too strong activation of the tone of the nervous system of the sympathetic node due to stress, emotions, intense physical or mental stress, alcohol consumption, smoking, etc. suffered by a person. Activation of the tone of the sympathetic node contributes to the occurrence of thyroid diseases, fever, blood diseases, and the production of viral toxins.

Vagodependent neurogenic arrhythmias are the activation of the parasympathetic system of the human body, especially the vagus nerve. Vago-dependent deviations in the rhythm of the heartbeat appear, as a rule, at night and provoke the development of diseases of the gallbladder, intestines, stomach, bladder, in which the vagus nerve is activated.

Diselectrolyte arrhythmias appear in the process of imbalance of electrolytes in the myocardium and in the blood, especially potassium, magnesium, sodium.

Iatrogenic heart rhythm disturbances begin to manifest themselves due to arrhythmogenic effects on the body of certain drugs, such as cardiac glycosides, beta-blockers, diuretics, sympathomimetics, etc. Mechanical arrhythmias appear as a result of trauma to the chest, blows, falls or electric shock. Idiopathic arrhythmias are abnormal heart rhythms without an underlying cause.

With the development of various kinds of arrhythmias, the main importance is given to the hereditary predisposition of a person to certain deviations in the state of health.

The vagus nerve is one of twelve nerves found in the human cranium. Its function is very important - it provides information to the brain about what is happening in the entire nervous system, and is responsible for controlling reflex function. The vagus nerve has a rather complex structure, including motor, secretory and sensory fibers. It is known that the fibers conduct impulses that enter the cerebral cortex, awakening all known functions. In particular, the fibers of the vagus nerve can slow down the heartbeat, constrict the bronchi, relax the sphincters and increase intestinal motility, increase the secretion of the glands, and much more. It is not surprising that damage to the vagus nerve can lead to numerous diseases of the body.

Why is the vagus nerve damaged in the human body?

There can be a huge number of reasons for its damage. Let's look at the most common ones. One of them is diabetes. Damage to blood vessels due to high blood sugar can lead to inflammation and even damage to the vagus nerve. By the way, other chronic diseases, such as HIV or Parkinson's disease, can also have a detrimental effect on such an important fiber. The vagus nerve suffers very strongly in severe accidents and injuries. Surgical intervention, when, under unforeseen circumstances, the patient's pressure on the vagus nerve increases sharply, can also lead to serious damage to it. Addictions, such as alcoholism, are another possible cause (alcoholic neuropathy).

What are the symptoms that there is damage to the vagus nerve?

Symptoms manifest themselves in different ways. It is quite natural that the more severe the injury, the more difficult the consequences can be. Most often, voice problems initially appear, such as hoarseness, difficulty in pronunciation, and even a noticeable change in voice. Dysphagia is the next stage, when problems with swallowing saliva and food begin. This is due to the fact that the vagus nerve is responsible for the tongue movement reflex, and damage to it determines movement dysfunction. Violation of the same reflex function can lead to an unreasonable gag reflex, which is fraught with suffocation. This is followed by digestive problems (indigestion, constipation, etc.), heart problems (arrhythmia, chest pain, respiratory failure and dizziness), urinary incontinence, and deafness.

How to treat the vagus nerve

Treatment is best done under the supervision of a specialist. Its significance is very high, since the problems that arise when the vagus nerve is damaged are extremely severe, and improper treatment or its absence can be fatal. The fact is that therapy in this case rarely helps, so the main methods of treatment are surgical intervention, electrical stimulation. With proper diagnosis, timely intervention and compliance with all treatment conditions, the restoration of the vagus nerve is just a matter of time.

There are two main types of vagus nerve disorders. One is caused by an underactive or inactive vagus nerve, and the other is caused by a vagus nerve that overreacts to common stimuli. Patients with underactive vagus nerves often experience severe gastrointestinal problems requiring long-term treatment. Those with overactive vagus nerves may often faint. This condition is not considered dangerous, although patients may be accidentally injured as a result of sudden fainting.

Vagus nerve disorders that result from a weak vagus nerve often result in a condition known as gastroparesis. Patients suffering from this disorder may experience stomach pain, nausea, heartburn, stomach cramps, and weight loss. These symptoms occur because the vagus nerve is unable to send enough blood to the stomach for proper digestion. In most cases, patients with gastroparesis will need to manage the condition medically for the rest of their lives.

A blazing vagus nerve can cause someone to often feel tired.

In some patients, vagus nerve problems can be seen in other systems as well. This nerve is partly responsible for maintaining heart rate and blood pressure, and if it is not functioning properly, patients may need a number of medical interventions to live. Pacemakers may be used to lower the heart rate, and medication may be needed in an acceptable range to increase blood pressure. Vagal nerve disorders that are so severe are rare and are often either congenital or result from severe disease or nerve damage.

A flaccid vagus nerve can lead to weight loss.

Vagus nerve disorder can be caused by a number of different causes. The vagus nerve drains blood to the stomach and can divert too much of it from the brain, causing the patient to vomit, indigestion, or frequent bowel movements. Stress and emotional stimuli can also cause the vagus nerve to divert too much blood from the brain.

Patients with overly sensitive vagus nerves may faint at the sight of needles.

What are the treatments for vagus nerves?

The vagus nerves both start in the brainstem, but each then extends down both sides of the neck to places like the heart and intestines. These nerves play a role in regulating breathing, heart rate, and digestion.

Patients with vagus nerve disorders may have a variety of symptoms, including low blood pressure, irregular heart rhythms, difficulty swallowing, and digestive problems. Treatment is often limited to reducing or eliminating symptoms with exercise and short-term or long-term medication, but surgery may also be required.

Pacemakers can significantly increase the life expectancy of patients with congenital heart disease.

Exercises for vagus disorders usually involve the pharynx, the area of ​​the throat between the mouth and larynx. The patient can also be taught how to massage the soft palate or the upper part of the mouth. Through a combination of vocalization, breathing techniques, and movement, exercise can stimulate the vagus nerves, thereby relieving some symptoms.

Patients with vagus nerve disorders may experience low blood pressure.

Patients with vagus nerve disorder may require the assistance of a pacemaker.

Pharynx exercises may be prescribed to help reduce the risk of problems associated with a vagus nerve disorder.

Although many patients with vagus nerve disease require little or no treatment, disorders can pose a significant risk. For example, some people may have a vagus nerve disorder in which the brain never receives a signal to notify it that the person is hungry and needs food. Without the hunger signal, the patient could literally starve.
