In particular, several studies have shown how the vagus nerve is involved in many vital processes during fetal, perinatal, and postnatal life: from the regulation of inflammation through the anti-inflammatory cholinergic pathway, which may affect the functioning of each organ, to the production of hormones involved in bioenergetic metabolism.
In addition, the vagus nerve has been recognized as the primary afferent pathway capable of transmitting information to the brain from every organ of the body.
The vagal nerve plays an integral part in functions of the body, e.g., stimulating salivation, gut peristalsis, and bladder contraction
