Inferior salivatory nucleus

The inferior salivatory nucleus is a paired cranial nerve nucleus of the ninth cranial nerve, the glossopharyngeal nerve, the brain stem. He is general viszeromotorisch and supplies the parasympathetic parotid gland.

Location

The core area is located in the upper portion of the medulla oblongata between two other nuclei of the cranial nerves. Lateral is the upper part of the Special- viszerosensibelen and general viszerosensibelen solitary tract nucleus, ventral to the upper portion of the Special- visceral efferent nucleus ambiguus.

Its efferent fibers leave the central area between the two above-mentioned core areas and interact with the other portions of the glossopharyngeal nerve in the sulcus behind the Olive from the brain stem from. A neighborhood relationship has the core also to dorsal longitudinal fasciculus (also called contactor bundle) which bears his dorsal.

Function

In the inferior salivatory nucleus are exclusively the first neurons of the parasympathetic innervation of the parotid gland. They are controlled via the already mentioned dorsal longitudinal fasciculus of hypothalamus. The core laughed send fibers reach the otic ganglion, where they are switched to a second neuron whose axons reach the parotid gland.
