Point 15. Superior Salivatory and Lacrimal Nuclei

We have already discussed two PREGANGLIONIC PARASYMPATHETIC (visceromotor) nuclei, the dorsal motor nucleus X (C.N. X) and the inferior salivatory nucleus (C.N. IX). Another area in the brain stem that contains preganglionic parasympathetic cell bodies is the SUPERIOR SALIVATORY-LACRIMAL nucleus. These cells lie in the pons, just medial to the MOTOR VII. Like the inferior salivatory nucleus, we cannot identify the superior salivatory and lacrimal nuclei.
