The Superior salivary nucleus (or superior salivatory nucleus ) of the facial nerve is a visceromotor cranial nerve nucleus located in the pontine tegmentum .
Parasympathetic efferent fibers of the facial nerve (preganglionic fibers) arise according to some authors from the small cells of the facial nucleus , or according to others from a special nucleus of cells scattered in the reticular formation, dorso-medial to the facial nucleus . This is sometimes called the superior salivatory nucleus .
These preganglionic fibers are distributed partly via the chorda tympani and lingual nerves to the submandibular ganglion , thence by postganglionic (vasodilator) fibers to the submaxillary and sublingual gland s.
Some of the preganglionic fibers pass to the sphenopalatine ganglion via the great superficial petrosal nerve .
