Inf. salivatory nuc. is a small collection of nerve cells in the dorsolateral part of pons or rostral medulla, just above its junction w/ the medulla.
It lies immediately caudal to the sup. salivatory nuc. and just above the upper end of the dorsal nuc, of CN10.
Dorsolateral reticular formation medial to nuc. solitarius.
Fibers:
Preganglionic fibres from this nucleus run in the glossopharyngeal nerve, enter its tympanic branch (nerve of Jacobson) and relay in the “otic ganglion” by way of tympanic plexus and lesser superficial petrosal nerve.
