Flashcards in palate, pterygopalatine fossa, paranasal structures Deck (46)
what are turbinates
the things that stick out into the nasal cavities
bones that form the pterygomaxillary fissure
maxillary on anterior side, pterygoid plate of sphenoid on the posterior side
what ganglion is in the pterygomaxillary fissure? and what is a nerve that goes into there
a pterygopalatine ganglion and a petrosal nerve. look it up.
if you have a pituitary tumor, how could you get in there to fix it
stick instruments up through the nose to the sella turcica
what canal conects the pterygopalatine fossa to the nose
what bone fits into the sphenoid?
what bones make the pterygopalatine fossa?
palatine bone on medial side, sphenoid posteriorly, maxilla anteriorly
palatine canal contains what nerves
palatine nerves that go to posterior edge of the palate (not sure hard or soft)
does he think that the palatovaginal groove is important?
not sure, its really small and its only purpose is for a litttttle blood vessel to nasopharynx
what are the five canals from the pterygopalatine fossa
palatine, palatovaginal, pterygoid, sphenopalatine foramen, and infraorbital
nerve through the sphenopalatine foramen?
the sympathetics that run through the fossa come from?
superior cervical ganglion that turns into a plexus around the ICA
do parasympathetics synapse in the peterygopalatine ganglion?
where do the pterygopalatine arteries come from?
maxillary. all of em.
review: post synaptic parasympathetics to the lacrimal gland synapse where?
what nerve goes around the middle meningeal artery
what is the elusive venous plexous?
pterygoid venous plexus in the infratermporal fossa.
what are some major veins that connect to the pterygoid plexus?
welp. i used to know this
why do your teeth hurt when your sinus hurts?
the superior dental plexus nerves run on the inferior edge of the mucous memebrane of the maxillary sinus. when it swells those guys get mad
meatus in your nose?
the groove underneath a nasal conche
greater and lesser palatine nerves are branches of?
where does the external nasal branch come from?
anterior ethmoidal from V1 (remember the nasociliary gave off some branches to the nose?)
sensory to the mucosa of the nose. CN?
besides V, what CN is in the nose?
don't think too hard. olfactory
lesser palatine nerve is sensory to?
CN for sensory of palate?
V2. you know this stuff!!
where does the maxillary sinus drain?
when you're sick, your nose runs. all of the sinuses drain to the nose!!
why do kids get ear infections?
the eustacian tube is horizontal between the ear and the nose. since theres not an incline, crap can get into the middle ear.
why do you have turbinates?
it creates TURBulance to warm and moisten air
