The airway vagal preganglionic neurons(AVPNs)supply the major cholinergic output to the trachea and bronchus.AVP-containing fibers are found in the close vicinity of AVPNs.In stress-induced asthma,the airway vagal or cholinergic excitation is found to make important contributions to the bronchoconstriction; and the central concentration of arginine vasopressin(AVP)is elevated.
