Preganglionic parasympathetic to otic ganglion
Term
what branch of the glossopharyngeal n provides GA from the mucous membranes of the pharynx
Definition
pharyngeal branch
Term
what branches of CN IX provide VA concerning blood pressure and gases?
Definition
carotid body and sinus brs
Term
what does the carotid sinus do?
Definition
its a baroreceptor that monitors blood pressure
Term
what does the carotid body do?
Definition
chemoreceptor
Term
what makes you gag? (afferent and efferent)
Definition
afferent: IX
efferent: x
Term
Tympanic n pathway: where does it branch off CN IX?
Definition
near jugular foramen where it enters ear via tympanic caniculus
Term
Tympanic n pathway: what nerve branches off the tympanic plexus in the middle ear?
Definition
lesser petrosal
Term
what hole does the lesser petrosal use to get from the ear to the middle cranial fossa?
Definition
hiatus for the lesser petrosal

Term
what happens to the lessr petrosal once it gets to the otic ganglion and where does it go from there?
Definition
it synapses and then its postganglionic parasym fibers are distributed via the auriculotemporal (V3) to the PAROTID GLAND!
