posterior lateral nasal
what are the 2 branches of posterior lateral nasal NERVE
posterior superior lateral nasal nerve
posterior inferior lateral nasal nerve
what nerve is the posterior superior lateral nasal n branch off of?
maxillary nerve (v2)
what nerve is the posterior inferior lateral nasal branch n off of?
greater palatine nerve (v2)
what does the nerves of the pterygoid palatine ganglion supply?
palatal mucosa, nasal mucosa, lateral wall and septal
what does the autonomic innervation of the pterygoid palatine ganglion do?
keep mucosa wet
what is another nerve branching off of the pterygoid palatine ganglion
what nerve is nasopalatine n branching from?
what canal does the nasopalatine n go through?
what cranial fossa is the foramen rotundum is?
middle cranial fossa
what nerve goes through the foramen rotundum
what does the V2 nerve enter when going through foramen rotundum

what goes through foramen lacerum??
NADA NOTHING DAMN IT IS STUPID
where do the preganglionic sympathetic fibers come from?
where do the postganglionic sympathetic fibers synpase
superior cervical ganglion
how does the postganglion symp fibers get to pterygoid palatine ganglion?
Hop on internal carotid plexus (ICA)
sympathetic fibers from the internal carotid plexus branch off to form what nerve?
deep petrosal nerve
where does the parasympathetic preganglionic fibers start?
geniculate ganglion of VII
what nerve branches off of geniculate ganglion to have parasympathetics fibers?
greater petrosal nerve
what is the path of parasympathetics?
geniculate ganglion of VII, greater petrosal, vidian nerve, pterygoid palatine ganglion
