Q

anesthetizing post superior alveolar n. anesthetizes what?

A

Maxillary Post. molars

20
Q

where to insert to anesthetize post sup alveolar n.

A

through buccinator m. above the molars

21
Q

When a dentist works on the vestibular gingiva (where buccal meets labial) overlying the max premolars they anesthetize which nerves?

A

middle superior alveolar n.

22
Q

sensation from the extreme ant. aspect of the hard palate travels back to the central nervous system in which nerve

A

nasopalatine

23
Q

Which nerve runs through the incisive foramen?

A

nasopalatine which serves ant. hard palate

24
Q

One or two nasopalatine n.

A

Two, there is a septum

25
Q

injection adjacent to 3rd molar is for what nerve?

A

greater palatine n.

26
Q

Injecting into V2 does what?

A

knocks out the entire maxilla basically

27
Q

Inject into palatine canal for what?

A

To knock out the whole V2 basically the whole upper

28
Q

lingual nerve is formed by what

A

Chorda tympani and lingual n.

29
Q

lesion to lingual n. before joining with chorda tympani does what

A

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

30
Q

lesion at foramen ovale to lingual n

A

only lingual n so sensory to ant tongue

31
Q

distal lesion near oral cavity to lingual n

A

gets chorda typani and lingual n so taste and sensory

32
Q

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

A

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

33
Q

nerve that goes up thru incisive foramen

A

nasopalatine- serves extreme ant. part of hard palate

34
Q

inject into palatine too fast you do what

A

strip the periosteum

35
Q

find greater palatine foramen, use long needle for what

A

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

36
Q

only sympathetic fiber in head

A

greater petrosal which joins lesser

37
Q

connects middle cranial fossa and infratemporal fossa

A

foramen ovale

38
Q

Can see in ear

A

chorda tympani which will meet lingual n. and go to floor of mouth

39
Q

Can damage with cutip

A

taste and salivary glands, chorda tympani

40
Q

Go through jugular foramen

A

IX, X, XI

41
Q

Effects moving head around

A

Spinal accessory CN XI-SCM

42
Q

Innervates heart and GI

A

CN X

43
Q

Dry mouth

A

CN X

44
Q

Gives off tympanic branch, what does this do then

A

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)

45
Q

Lesser petrosal n. goes through

A

Foramen ovale
