The vagus nerve supplies parasympathetic motor fibers to the myocardium. VM involve different techniques used to stimulate aortic baroreceptors located within the walls of the aortic arch and within the carotid bodies. These receptors trigger an increase in vagal tone, which stimulates a bradycardia response at the level of the AV node. A vagal episode, also known as vasovagal syncope, is a common cause of fainting that leads to a brief period of unconsciousness. According to Mayo Clinic, the condition is generally harmless, but a person experiencing a vagal episode may become injured upon fainting. Vasovagal reflex syncope is the most frequent cause of transient loss of consciousness.

It’s like a green light for normal life. How does this look and feel? The dorsal vagal complex connects to the organs underneath the diaphragm including the stomach, spleen, liver, kidneys, as well as the small and large intestines. The ventral vagal, social nervous system connects above the diaphragm to your heart, lungs, larynx, pharynx, inner ear, as well as the facial muscles around your mouth and eyes. There is adaptation of the cardiac vagal efferent responses to stimulation of the arterial baroreceptors by a series of brief intracarotid pressure pulses, by a sustained elevation of pulsatile systemic pressure, or by sustained steady increases in intracarotid pressure. This was demonstrated here in experiments on anaesthetized dogs. 2.
