Glossopharyngeal CN IX Flashcards
the glossopharyngeal nerve carries motor innervation to
styopharyngeous muscle
motor fibers carried in CN IX arise from cell bodies located where
in the superior part of Nucleus Ambiguous
carries sensory information from
pharynx, invluding taste info from posterior tongue
afferent sensory fibers terminate where
solitary nucleus
carries parasympathetic information ultimately leading to
parotid gland
preganglionic parasympathetic fibers arise from the
inferior salivatory nucleus
two peripheral ganglia associated with the glossopharyngeal nerve
superior ganglion and inferior ganglion
apparent origin of glossopharyngeal nerve
superior aspect of the MO
preganglionic parasympathetic information traveling in CN IX synapse where
otic ganglion
after the synapse in the otic ganglion, postganglionic fibers arise that supply
parotid glands, buccal glands, inferior labial glands
general sensory information is carried in glossopharyngeal nerve branches from:
nasopharynx, oropharynx, tongue posterior to sulcus terminalis, uvula + palatine tonsils
general sensation from ____ cavity is carried in a branch of glossopharyngeal nerve
tympanic
taste information from the tongue posterior to sulcus terminalis is carried by neurons from the
inferior ganglion
glossopharyngeal nerve exits skull via
jugular foramen
the superior ganglion is located
inside of the cranium
