What can be caused by vagus nerve excitation, vagus nerve excitation can cause .

Acetylcholine receptors are released and the heart rate slows down vasoconstriction.

Answer]: A When the vagus nerve is excited, the main manifestations are slowing down the heart rate, dilating blood vessels, decreasing blood pressure, accelerated gastrointestinal peristalsis, abdominal pain caused by smooth muscle spasm, and symptoms such as malignant and relieved heart, vomiting and vomiting.

Answer]: A vagus nerve belongs to the parasympathetic nervous system, which antagonizes the sympathetic nervous system to adjust the body's heart rate, respiration, gland secretion, and blood flow distribution of important organs such as liver and adrenal glands. The vagus nerve innervates most of the organs of the respiratory and digestive systems, as well as the sensory disturbances of the heart, movement, and the absence of the glands of the sedan chair.

Vagus nerve excitation can cause symptoms of sympathetic depression (i.e., vagal excitation) such as lightheadedness, drooping eyelids, tearing, nasal congestion, and bradycardia.

a.Gastrointestinal smooth muscle activity is increased, and secretion of digestive glands is reduced.

b.Gastrointestinal smooth muscle activity is weakened, and secretion of digestive glands is increased.

c.Gastrointestinal smooth muscle activity is enhanced, and secretion by the digestive glands is increased.

d.Gastrointestinal smooth muscle burning plexus buried active skin ant reduction Zheng Chan weakness, digestive gland secretion decreased.

Correct answer: Gastrointestinal smooth muscle activity is enhanced, and secretion of digestive glands is increased.

When the vagus nerve is excited, the following statements are true:

a.Gastrointestinal smooth muscle activity is enhanced, and secretion of digestive glands is increased.

b.Gastrointestinal smooth muscle activity is increased, and secretion of digestive glands is reduced.

c.Gastrointestinal smooth muscle activity is weakened, and secretion of digestive glands increases.

d.Gastrointestinal smooth muscle activity is weakened, and digestive glands are reduced.

Correct answer: Gastrointestinal flat spine sliding muscle activity is enhanced, and the secretion of the hypoosmotic gland is increased.

a.It can increase the heart rate.

b.Increased atrial muscle contractility.

c.It can slow down the heart rate.

d.Atrioventricular conduction velocity is accelerated.

e.Left ventricular systolic blood pressure is elevated.

Correct answer: c

Tell you a recipe that my mother found for me when I was a child, and it works very well. Adult black dot stewed old black hen eats black beans and drinks soup.

It is a symptom caused by qi deficiency, which can be dispersed with a jade screen**.

Vagus nerve excitation is manifested as headache, dizziness, enlarged eye clefts, blurred vision, dilated pupils, rapid heartbeat or even irregular heartbeat, limb chills, sweating disorders and other sympathetic nerve excitation or dizziness, eyelid drooping, tearing, nasal congestion, bradycardia and other frequent attacks, a small amount of anxiolytic drugs such as diazepam can be tried; Anticholinergic drugs such as prometalin, etc. It can inhibit the vagus nerve, delay food absorption and reduce insulin secretion.

The vagus nerve is the 10th cranial nerve pair, which is the longest and most widely distributed pair of cranial nerves, containing sensory, motor, and parasympathetic nerve fibers.

The vagus nerve innervates most of the organs of the respiratory and digestive systems, such as the heart, sensory, motor, and glandular secretions. As a result, vagus nerve damage can cause circulatory, digestive, and respiratory dysfunction.
