1

what are turbinates

the things that stick out into the nasal cavities

2

bones that form the pterygomaxillary fissure

maxillary on anterior side, pterygoid plate of sphenoid on the posterior side

3

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.

4

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

5

what canal conects the pterygopalatine fossa to the nose

pterygoid canal

6

ethmoid.

7

what bones make the pterygopalatine fossa?

palatine bone on medial side, sphenoid posteriorly, maxilla anteriorly

8

palatine canal contains what nerves

palatine nerves that go to posterior edge of the palate (not sure hard or soft)

9

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

10

what are the five canals from the pterygopalatine fossa

palatine, palatovaginal, pterygoid, sphenopalatine foramen, and infraorbital

11

nerve through the sphenopalatine foramen?

nasal/nasopalatine nerve

12

the sympathetics that run through the fossa come from?

superior cervical ganglion that turns into a plexus around the ICA

13

do parasympathetics synapse in the peterygopalatine ganglion?

of course!!

14

where do the pterygopalatine arteries come from?

maxillary. all of em.

15

review: post synaptic parasympathetics to the lacrimal gland synapse where?

pterygopalatine ganglion.

auriculotemporal nerve

17

what is the elusive venous plexous?

22

where does the external nasal branch come from?

anterior ethmoidal from V1 (remember the nasociliary gave off some branches to the nose?)

23

24

besides V, what CN is in the nose?

don't think too hard. olfactory

25

it creates TURBulance to warm and moisten air

30

spheno-ethmoidal recess
