What C.N. will be utilized in parasympathetic innervation of the parotid gland?

- glossopharyngeal
- trigeminal


How will sympathetics innervate the parotid salivary gland?

by way of a neurovascular plexus around the external carotid artery


What is the parasympathetic/VE nucleus of origin for C.N. IX?

inferior salivatory nucleus


The glossopharyngeal n. will originate from what part of the brain?

the medulla oblongata


Preganglionic parasympathetic efferent fibers from C.N. IX will synapse in which ganglion?

otic/Arnold's ganglion


Postganglionic parasympathetic efferent fibers from the otic/Arnold's ganglion will join with what other C.N. branch?

the auriculotemporal branch of the mandibular division of the trigeminal


The parasympathetic pathway from C.N. IX will innervate what target?

parotid gland


What action will parasympathetic innervation have on the parotid gland?

vasodilation of arteries resulting in a thinner, watery, or whey-like saliva


What is the site of synapse of the preganglionic sympathetic VE fiber in the pathway to the parotid gland?

the superior cervical paravertebral ganglion


What is the postganglionic sympathetic innervation of the parotid gland derived from?

the superior cervical paravertebral ganglion


What is the pathway for the postganglionic sympathetic VE fiber to the parotid gland?

VE fibers surround the external carotid artery to form a neurovascular plexus


What arterial neurovascular plexuses will innervate the parotid gland?

- superficial temporal
- transverse facial
- posterior auricular
