Vestibulovegetative Reactions

Vestibulovegetative Reactions: Changes that occur when the receptor apparatus of the labyrinth is stimulated

Vestibulovegetative reactions are complex changes that occur in the human body when the receptor apparatus of the labyrinth - the inner ear, responsible for maintaining balance and coordination of movements - is irritated. These reactions include changes in blood pressure, heart rate, breathing, sweating, skin temperature and saliva secretion.

One of the key factors that plays an important role in vestibulo-autonomic reactions is the activation of the vestibular system. When the receptors in the inner ear are stimulated, signals are sent to the brain centers responsible for regulating the autonomic functions of the body. This leads to a wide range of changes aimed at adapting the body to new conditions or eliminating emerging problems.

One of the most noticeable manifestations of vestibulo-vegetative reactions is a change in blood pressure. When the labyrinth receptors are irritated, the sympathetic nervous system is activated, which leads to a narrowing of peripheral vessels and an increase in blood pressure. This phenomenon may be especially noticeable when the body changes position or makes sudden movements.

In addition, vestibulovegetative reactions can cause changes in heart rate and respiration. When the vestibular system is activated, an increase in heart rate and respiratory rate is observed. This occurs as a result of activation of the sympathetic nervous system and increased sympathetic tone.

Another important aspect of vestibulo-vegetative reactions is changes in sweating and skin temperature. Under the influence of activation of the vestibular system, sweating increases, especially in the forehead, palms and feet. This is due to the activation of the sympathetic nervous system, which controls the sweat glands. In this regard, an increase in skin temperature may be observed.

In addition, vestibulovegetative reactions can cause changes in salivary secretion. When the vestibular system is activated, the secretory activity of the salivary glands is stimulated, which leads to increased secretion of saliva.

All these changes are normal physiological reactions of the body to irritation of the receptors of the labyrinth. Vestibulo-vegetative reactions are complex changes that occur in the body in response to irritation of the receptor apparatus of the labyrinth - the inner ear. These reactions involve various systems and functions of the body, including the circulatory system, breathing, sweating, skin temperature and saliva secretion.

One of the main aspects of vestibulo-vegetative reactions is changes in blood pressure. When the labyrinth receptors are irritated, the sympathetic nervous system is activated, which leads to a narrowing of peripheral vessels and an increase in blood pressure. This mechanism helps maintain blood pressure at an optimal level and ensure sufficient blood supply to organs and tissues.

In addition, vestibulovegetative reactions can affect heart rate. When the vestibular system is activated, an increase in heart rate is observed, which is associated with excitation of the sympathetic innervation of the heart. This helps ensure increased blood perfusion of organs and tissues under conditions of increased activity or stress.

The respiratory system is also influenced by vestibulo-vegetative reactions. When the labyrinth receptors are irritated, an increase in respiratory rate is observed. This phenomenon is associated with activation of the sympathetic nervous system and increased sympathetic tone of the respiratory muscles.

Vestibulovegetative reactions can also manifest themselves through changes in sweating and skin temperature. Under the influence of activation of the vestibular system, sweating increases, especially in the forehead, palms and feet. This is due to the activation of the sympathetic nervous system, which controls the sweat glands. In addition, vestibular irritation can cause a mild increase in skin temperature as a result of capillary dilation and increased blood flow in superficial vessels.

Another aspect of vestibulo-vegetative reactions is a change in salivary secretion. When the vestibular system is activated, the secretory activity of the salivary glands is stimulated, which leads to increased secretion of saliva. This process may be associated with improved digestion and oral defense mechanisms.

In general, vestibulo-vegetative reactions are a complex systemic adaptive response of the body to stimulation of the labyrinthine receptors. They are playing

Vestibular reactions: symptoms and causes

The vestibular apparatus is a part of the nervous system that is responsible for maintaining the balance of the body. The vestibular apparatus is located in the pyramids of the temporal bones, and its receptors are located in the inner ear. When we move or turn our head, signals from the vestibular system enter the brain, allowing us to maintain balance and coordination of movements. However, under certain conditions this system can malfunction, causing various vestibulopathic reactions.

Symptoms of vestibular reactions:

- Dizziness, which may be accompanied by nausea and vomiting; - Loss of balance and coordination of movements; - Weakness and fatigue; - Increased sweating or, conversely, dry skin; - Rapid heartbeat and high blood pressure; - Sleep and appetite disorders; - Numbness or muscle pain in the head, neck or back; - Nausea, headache and other symptoms associated with motion sickness and seasickness.

The causes of vestibular disorders can be different. This can be caused by brain injuries, infectious diseases (for example, meningitis), toxin poisoning, pathologies of the nervous system, etc. Sometimes the cause can be ordinary stress. But the most common is changes in blood pressure during pumping and dizziness of a person.

It is important to understand that vestibular disorders are not an independent disease, but rather a symptom of certain pathologies. Treatment is aimed at eliminating the cause of vestibular-vegetative disorders. First of all, you need to consult a neurologist or therapist. Treatment may include medications, physical therapy, and vestibular strengthening exercises.
