- Inferior ganglion of vagus nerve
Nerve: Inferior ganglion of vagus nerve Plan of upper portions of glossopharyngeal, vagus, and accessory nerves. ("Gang. nodosum" visible at center.) Latin ganglion nodosum, ganglion inferius nervi vagi. Gray's subject #205 911 From vagus nerve MeSH Nodose+Ganglion
The nodose ganglion (ganglion of the trunk; inferior ganglion of vagus nerve) is cylindrical in form, of a reddish color, and 2.5 cm. in length.
As opposed to the jugular ganglion of the vagus nerve, the inferior or nodose ganglion is larger.
It is chiefly visceral afferent in function concerning sensation of heart, larynx, lungs and alimentary tract from the pharynx to the transverse colon. These visceral afferents synapse centrally in the nucleus solitarius.
Both ganglia are traversed by parasympathetic, and perhaps some sympathetic fibres.
Preganglionic motor fibres (ganglionic branches) from the dorsal vagal nucleus and the special visceral efferents from the nucleus ambiguus, which descend to the inferior vagal ganglion form a band skirting the ganglion.
