Autonomic nervous systemThe nervous system It is the tissue network responsible for capturing and processing internal and external signals so that the body can develop an effective interaction with the environment. This system feels the stimuli (sensitive function), analyzes them, saves information and promotes a decision in this regard (integrative function), which is translated into muscle movement, glandular secretion, etc. (motor function).

In an anatomical sense, the nervous system can be divided into Central Nervous System or CNS (made up of the brain and spinal cord) and peripheral nervous system or SNP (made up of the cranial nerves and the spinal nerves). From a functional point of view, however, it is possible to divide the nervous system into autonomic nervous system Y somatic nervous system.

The autonomic nervous system or vegetative nervous system receive the information from the internal environment and sends a response to the muscles, glands and blood vessels. The functions of this nervous system are involuntary and they are activated from nerve centers found in the hypothalamus, brain stem, and spinal cord.

Some of these involuntary actions are the heartbeat and the movements of the blood vessels. When the system autonomic nervous is affected, various disorders of varying severity can occur, such as: heart problems; erectile dysfunction; blood pressure problems; difficulty breathing and swallowing.

What the autonomic nervous system does is transmit impulses from the central nervous system to the periphery, stimulating the organs. Blood circulation, respiration, digestion and metabolism are some of the functions bodies regulated by the autonomic nervous system.

The functional division of the autonomic nervous system allows us to speak of the sympathetic system (consisting of paravertebral nodes and prevertebral or pre-aortic nodes), parasympathetic system (isolated nodes) and enteric nervous system (which controls the gastrointestinal system).

The disorders that are generally associated with the autonomic nervous system can appear in isolation, or as a consequence of other diseases, including diabetes, Parkinson’s disease and alcoholism. In addition, one can speak of disorders that affect the entire system or part of it, as occurs with complex regional pain syndromes.

Autonomic nervous systemSome of the autonomic nervous system problems are transitory, although many others tend to worsen with the passage of weather. Disorders that attack heart function or breathing can be life-threatening. When there is an underlying disease (the main one, which causes the problems in question), improvements are sometimes possible if it is treated directly, although more often there is no cure and therefore treatments are aimed at symptoms become less aggressive.

Here are some concepts related to the autonomic nervous system:

Dysautonomia

Dysautonomia is a condition It encompasses almost all diseases or dysfunctions of the autonomic nervous system and can manifest itself in different ways, depending on the person. Usually there are sudden drops in blood pressure and heart rate, nausea, vomiting, and dizziness.

Palmar sweating

Also called palmar hyperhidrosis, palmar sweating is an autonomic nervous system reaction that goes hand in hand with anxiety, fear, and despair. This disorder considerably affects the quality of life and is the subject of various clinical investigations, some of which indicate that voluntary control is possible.

Heart rate

The stress Psychological can produce reactions on the part of the autonomic nervous system that directly affect the heart rate even if there is no cardiovascular condition. Although voluntary control is not possible, it is possible to regulate this problem through assisted control of the respiratory rate.
