What is the composition of the autonomic nervous system, what is autonomic nerve?

Many people are confused about the concept of autonomic nerves, in fact, autonomic nerves are figurative representations, which can normally perform activities, such as reaching out to grasp things, and the nerves that innervate the movement of the hand are called somatic nerves, which are nerves that can move at will. There is also a kind of nerve corresponding to it, called autonomic nerve, which is not controlled by subjective will, and its function is mainly to regulate the internal environment in the body, regulate the function of the gastrointestinal tract, and regulate the excitability of nerves.

Autonomic nerves are very important for maintaining the stability of the internal environment and maintaining good health. If the autonomic nerves are dysfunctional, there will be internal environmental disorders, insomnia, neurasthenia, and various internal organ diseases.

Autonomic dysfunction varies from person to person, and everyone's symptoms are different.

Some people may feel unable to sleep and insomnia, in this case, it is necessary to carry out psychological conditioning and use some anti-anxiety drugs. Some people feel that their heart is beating too fast and can take some heart-rate-lowering medications. Some people feel that their chest is tight and breathless, so they can get oxygen.

There are also some people who have some gastrointestinal discomfort and can take some medications to help digestion. In addition, some people may feel that their hands sweat too much or do not sweat, and they also need to be carried out accordingly.

After autonomic nerve dysfunction, the patient's daily activities will be affected, such as sleep, eating, sweating function, digestive function, the patient should go to the hospital for treatment as soon as possible, autonomic nerve dysfunction belongs to the neurology department, to take medication regularly according to the doctor's requirements, take enough treatment, and can not stop the drug suddenly. Avoid smoking, drinking, and staying up late. In addition, avoid putting too much pressure on yourself during the period, such as overtime or high-intensity tasks, which will increase the difficulty.

The human nervous system is divided into two categories, one is the voluntary nerves, which can be controlled by people at will; The other type is the involuntary nerves, also known as autonomic nerves, which cannot be controlled by the human will. If you can't control it at will, what's the use of coming? It's very useful!

Autonomic nerves are mainly found in the visceral, cardiovascular, and glandular areas. Heartbeat, breathing, and digestive activity are all regulated by it. The autonomic nerve is divided into two categories: sympathetic nerve and parasympathetic nerve, which often resist and coordinate with each other to form an organic whole with tacit understanding, so that the internal organ activities can adapt to the needs of the internal and external environment.

The sympathetic nervous system is the system responsible for "fight or flight", while the parasympathetic nervous system is responsible for "resting, digesting, eating, and reproducing". When the sympathetic nervous system is excited, it manifests as a rapid heartbeat, rapid breathing, dilated blood vessels, sweating, and dilated pupils in order to "fight or flight."

If a person is in a state of sympathetic nervous excitation for a long time, it can lead to autonomic nerve dysfunction. The autonomic nervous system cannot be controlled at will, just like a disobedient child, not just want him to be obedient.

The autonomic nervous system is related to the organs, glands, and blood vessels of the whole body, and is related to the regulation of sugar, salt, water, fat, body temperature, sleep, blood pressure, etc., so autonomic nervous disorders can cause discomfort in multiple organs of the body, and the manifestations involve the cardiovascular system, respiratory system, digestive system, endocrine system, metabolic system, and genitourinary system. etc., giving people the feeling of "all body is sick".

Although we cannot control the autonomic nervous system at will, there are some methods to restore the dysfunctional autonomic nervous system. Just like making an obedient child well-behaved, brute force is often counterproductive, and it is necessary to respect his characteristics and adopt appropriate methods in order to achieve the goal.

Autonomic nerve, which should be called autonomic nerve or autonomic nerve, is an inseparable part of the entire nervous system through the hypothalamus, brainstem and spinal cord under the regulation of the cerebral cortex, which can innervate the smooth muscle and secretory glands of the body, regulate the physiological activities of internal organs, maintain the balance of the body's internal environment and cooperate with the somatic nerve activities of the whole body.

The autonomic nervous system (VNS) is an efferent nerve in splanchnic nerve fibers, also known as an autonomic nerve; The autonomic nervous system is responsible for life-critical physiological functions, such as heart beat, respiration, digestion, blood pressure, metabolism, etc. The autonomic nervous system (autonomic nervous system) is a control system that largely unconsciously regulates bodily functions such as heart rate, digestion, respiration rate, pupil response, urination, and sex drive.

The system is mainly used to control "stress" and "emergency" responses. "The autonomic nervous system, also known as the autonomic nervous system, refers to the transmission nerves in the splanchnic nerve fibers, also known as the autonomic nerves. The master of the autonomic nervous system, life-threatening physiological functions, such as heart beat, respiration, digestion, blood pressure, metabolism, etc.

In addition, the autonomic nervous system is a control system, which is largely unconscious and regulates bodily functions, such as heart rhythm, digestion, respiration, rate, pupils, response to urination, and sexual impulse, so the autonomic nervous system is not controlled by this cerebral cortex.

Autonomic disorders can also lead to gastrointestinal disorders. Some patients may experience headache, dizziness, head suffocation, dullness, tightness in the head, or a feeling of weight, and some patients may experience dizziness, numbness, swelling of the eyes, dryness, blurred vision, uncomfortable facial limbs, tightness and dampness at the back of the neck, tightness and stiffness around the limbs, which are all related to autonomic nerves.

Autonomic nerve is another type of nervous system in the human body.

He is not controlled by human consciousness.

For example, the beating of the heart is controlled by autonomic nerves.

Autonomic dysfunction refers to the disorder of the body system that is originally controlled and regulated by the autonomic nerve, which causes or causes some physical symptoms to a certain extent.

Generally, at the beginning, it is palpitation, nausea, etc., and in severe cases, dizziness will occur, and physical exhaustion can be divided into adjustment** and medication**.

Regulation**Mainly to change one's own living habits to restore the nervous system to normal Suitable for mild patientsDrugs** Mainly to take some hormonal drugs and control neuromodulation by medical means.

The spinal nerves originate from the spinal cord and are mainly distributed in the trunk and limbs, and are responsible for motor and sensory. The splanchnic nerves emitted from the brain and spinal cord are mainly distributed in the internal organs, controlling and coordinating the functions of internal organs, blood vessels, glands and other functions. Because it is not governed by human will, it is called autonomic nerve, also known as autonomic nerve.

Autonomic nerves, including sympathetic and parasympathetic nervous systems, belong to the autonomic nervous system, and their function is to control effectors such as the heart, smooth muscle, and glands.

The patient's heartbeat, breathing and some digestive system functions are regulated by autonomic nerves, and can also participate in the regulation of blood vessels, water electrolytes and blood pressure, and the clinical manifestations of autonomic nerve dysfunction are complex, and abnormal clinical symptoms such as cardiovascular, digestion and endocrine can appear, most of which are insomnia, inattention and dizziness and other clinical symptoms. The sympathetic nerves originate from the spinal nerves and are mainly found in the viscera, cardiovascular system, and glands. The parasympathetic nerves are divided into cerebral and sacral vertebral parts, usually located on the central axis of the animal body, and consist of prominent cranial ganglia, nerve cords, or cerebrospinal cords.

It should be noted that bathing and massage can improve blood circulation, but long-term bathing should be avoided to avoid causing discomfort.

The nervous system is the dominant system in the body. After receiving various information from the internal and external environment by the receptors, it is transmitted to the centers at all levels of the brain and spinal cord through the peripheral nerves for integration, and then the peripheral nerves control and regulate the activities of various systems and organs of the body, so as to maintain the relative balance between the body and the internal and external environment. The functions of various organs and systems of the human body are directly or indirectly under the regulatory control of the nervous system, which is the regulatory system that plays a leading role in the whole.

The human body is a complex organism, and the functions of various organs and systems are not isolated, they are interconnected and mutually restricted; At the same time, the human body lives in a constantly changing environment, and changes in the environment affect various functions in the body at any time. This requires rapid and perfect adjustment of various functions in the body, so that the body can adapt to changes in the internal and external environment. The nervous system is primarily the nervous system.

The nervous system includes the brain, spinal cord, peripheral nerves and visceral nerves, and the nervous system can sense various information from the external environment, and transmit it to the central nervous system through the peripheral nervous system for integration and various responses.

Plants do not have a nervous system, but plants can transmit dangerous messages with the help of systems similar to those of animals.

The scientists explained that when the leaves of the plant are damaged, the stems and leaves of the plant are "informed" of all this due to changes in the amount of calcium. Molecular sensors that can detect fluorescent substances that react to calcium levels have been manufactured in the laboratory.

In the course of the study, the experts also found increases and decreases in calcium levels in plants under different conditions. Scientists believe that these changes create pulsations that are transmitted from one neuron to another and signal dangerous information.

Autonomic nerve is the motor nerve in the visceral nerve, also known as the autonomic nerve, which is composed of sympathetic nerves and parasympathetic nerves.

Sympathetic nerves arise from spinal nerves and are mainly found in the viscera, cardiovascular, and glandular areas. The sympathetic nerve is mainly responsible for some physiological activities when the human body is in a state of nervous activity, such as dilated pupils, increased heart rate, constriction of internal blood vessels, increased blood pressure, bronchiectasis, decreased saliva secretion, and decreased sweating.

The parasympathetic nerves are mainly emanating from the pons, midbrain, medulla, and sacral part of the spinal cord, and are often distributed on the central axis of the body. It is mainly responsible for some physiological functions of the human body when it is resting quietly. For example, pupils are constricted, heart rate is slowed, blood pressure is lowered, and the secretion of digestive juices increases, which promotes the passage of urine and urine.

Autonomic nerve refers to the nerve that regulates the secretion of splanchnic nerves and glands, which cannot be controlled by consciousness, so it is also called autonomic nerve, which can regulate gastrointestinal movement and heart beating, as well as the appearance of urination and defecation reflexes, collectively known as autonomic nerves, which are mainly involuntary movements.

In addition, the nerves that emanate through the vagus nerve, parasympathetic nerve, and some sympathetic centers innervate the heart, blood vessels, respiratory, lacrimal glands, submandibular glands, sublingual glands, digestive glands, and the nerves secreted by the bowel movement, urination function, and sweat glands are called autonomic nerves.
