<prompt> All of the following statements about vagus nerve are true except that itSupplies heart and lungCaries postganglionic parasympathetic fibersInnervates right two third of transverse colonStimulates peristalsis and relaxes phincters  <response>: Parasympathetic general visceral efferent out flow of vagus is through preganglionic fibers, as postganglionic neurons related to vagus are located in thoracic and abdominal autonomic plexus, close to or, within, the viscera supplied. It suppliesGastrointestinal tract from pharynx to the junction of the right 23rd and left I3rd of transverse colonThe left 13rd of transverse colon, descending colon, the sigmoid colon, rectum and upper part of anal canal are supplied by sacral part of parasympathetic system. As a rule, parasympathetic nerve stimulate intestinal movements and inhibit the sphincters, they are secretomotor to mucosa glands.Heart and lung the parasympathetic preganglionic neurons are located in the dorsal nucleus of vagus and stimulation reduces heart rate and leads to broncho constriction
