All of the following statements about the vagus nerve are true EXCEPT
Supplies hea and lung
Carries postganglionic parasympathetic fibers
Innervates right two third of transverse colon
Stimulates peristalsis and relaxes sphincters
Cranial nerve 3, 7, 9 and 10 (vagus) carry the preganglionic (and not post-ganglionic) parasympathetic fibers. It supplies the parasympathetic fibers to lungs and hea, and the GI system till the mid-gut. The right 2/3 of the transverse colon belongs to mid-gut and is supplied by the vagus nerve.
