CN VII (Facial) (para) Flashcards
Preganglionic cell bodies of the facial nerve are found were? and what part?
superior part of the salivary nucleus
the facial nerve exits the CNS in what nerve and carried in two branches
intermediate nerve
what are the two branches of the facial nerve that carrie Parasympathetic innervation
Greater petrosal nerve and the chord tympani
when does the greater petrosal nerve leave the facial nerve
at the geniculate ganglion
upon leaving the facial nerve at the geniculate ganglion what type of fibers are being carried in the greater petrosal nerve
preganglionic parasympathetic
the greater petrosal nerve carries preganglionic fibers anterior ward through what hiatus
hiatus for the greater petrosal nerve
the greater petrosal nerve will reenter the petrous part of the temporal bone through what?
foramen lacerum
the greater petrosal nerve will travel in the pterygoid canal to ultimately join with what?
the pterygopalatine ganglion
post ganglionic fibers of the greater petrosal nerve are then distributed in what two nerves out of the pterygopalatine ganglion
lacrimal and pterygopalatine nerves
postganglionic para- fibers that are distributed via the lacrimal and pterygopalatine nerves to reach what
lacrimal, nasal, palatine and pharyngeal glands
The chord tympani carries preganglionic parasympathetic fibers through which cavity when leaving the temporal bone through what fissure?
tympanic cavity and pterygotympanic fissure
From the pterygotympanic fissure the chord tympani will combine with which nerve
the lingual nerve, a branch of the mandibular division of the trigeminal nerve
the chorda tympani preganglionic fibers leave the lingual nerve to reach what ganglion?
submandibular ganglion
from the submandibular ganglion what fibers will travel to the submandibular and sublingual glands?
postganglionic
what also receives parasympathetic information from the submandibular ganglion?
glands found in the mucous membrane of the oral cavity and lingual glands on the anterior part of the tongue
