Pterygopalantine fossa Flashcards
Ant, post, sup and inf borders of the pterygopalantien fossa
ant- maxillary body
post- root of pterygoid process
sup- greater wing of sphenoid
inf- pyrimidyal process
What does the pterygopalantine fossa connect with (6)
Pterygomaxillary fissue inf orbital fisure great+less palantine for Sphenopalantine foramen foramen rotundum pterygoid canal
what is the main branch that goes to the pterygopalantine fossa
Maxillary div of CNv
Path of maxillary div of CNV
passes thru foramen rotundum to pterygopalantine fossa sends branches that go thru IOF and palantine fossa
what is the sympathetic n that travels with the maxillary div to decrease secreation of glands
deep petrosal n
what are the 2 main terminal nerves of the maxilary div
- Paryngeal (great+lesser palantine)
2. Nasopalantine (post lat sup + inf nasal, sphenopalantine + insicive)
What does the internal nasal n supply
continuation of opthalmic
somatosensation of the ant sup part of the lat wall of nasal septum
what does the pharyneal n supply
mucuosa of nasopharynx and auditory canal
what does the sphenopalantine n supply
To post inf part of nasal septum
what part of the maxillary artery lies ant to pterygopalantien g and supplies all the nerves
3rd part (pterygopalantine part) of maxillary artery
what passes thru/ synapses in the pterygopalantine g
Sensory- maxillary n passes thru
Sympathetic- deep petrosal passes thru
parasympathetic- greater petrosal synapses
