Vasovagal syncope occurs as a result of increased activity of the vagus nerve, the mainstay of the parasympathetic nervous system.

Dear R . H . : There is a system of nerves in your body called the parasympathetic nervous system.
23.
The parasympathetic nervous system, which uses acetylcholine almost exclusively to send its messages, is said to be almost entirely cholinergic.
24.
This influx of positive charge induces the release of acetylcholine into the body to interact with the parasympathetic nervous system.
25.
Perhaps reflexology works by causing relaxation due to the pleasure which is in effect stimulation of the parasympathetic nervous system.
26.
In chronic heart failure the sympathetic nervous system is over-activated and the parasympathetic nervous system depressed, increasing stress on the heart.
27.
ACh is used by the parasympathetic nervous system to activate muscarinic receptors and by the neuromuscular system to activate nicotinic receptors.
28.
The negative feedback loop is then needed to return the body to its resting state by signaling the parasympathetic nervous system.
29.
Sensory stimuli from food activate dorsal motor nucleus of vagus nerve in the medulla ( activating the parasympathetic nervous system ).
30.
Now we know it works through the parasympathetic nervous system, and is related to sweating, smooth muscles and even some skin conditions,
