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 [[submandibular gland]] and [[sublingual gland]].
Some of the [[preganglionic]] fibers pass to the [[sphenopalatine ganglion]] via the [[greater petrosal nerve]].
The term "lacrimal nucleus" is sometimes used to refer to a portion of the superior salivary nucleus.<ref>{{BrainInfo|ancil|329}}</ref>
