only takes out sensory to ant. 2/3 sensory to tongue

Question 30

lesion at foramen ovale to lingual n

only lingual n so sensory to ant tongue

Question 31

distal lesion near oral cavity to lingual n

Answer 31

gets chorda typani and lingual n so taste and sensory

Question 32

Injecting under the eye to hit the infraorbital does not get post. sup alveolar why

Answer 32

because it is not a branch of the infraorbital but instead comes out of the pterygopalatine fossa

Question 33

Answer 33

nasopalatine- serves extreme ant. part of hard palate

find greater palatine foramen, use long needle for what

Answer 35

advance needle up palatine canal to knock out all of V2 thus the entire hard palate-takes out parasympathetics too

CN Ix, tympanic branch goes into middle ear to tympanic plexus and then via lesser petrosal through foramen ovale n goes to otic ganglion and rides on auriculotempolar n. (branch of CNV)

Lesser petrosal n. goes through

Answer 45

Foramen ovale
