Q

White rami: entering or exiting sympathetic ganglion?

A

White in

Gray out

21
Q

is there a symp ganglion in head?

A

no.

22
Q

Tearing up

A

parasympathetic

23
Q

symp in the face

A

dilator pupillae, tarsal muscle of eyelid, sweating of face

24
Q

ptosis

A

droooping eyelid

25
Q

horners syndrome

A

ptosis, miosis, anhidrosis

26
Q

What do parasymp fiers do to eye

A

round up lens and constrict pupil

27
Q

in between internal jugular and common carotid is…

A

CN X

28
Q

CN VII goes through which 2 ganglion?

A

pterygopalatine ganglion (goes to lacrimal gland, hitching a ride with CN V, and also nasal mucosa)

submandibular gland

29
Q

pneumonic for otic ganglion

A

GLOAP

30
Q

How do the branches of CN VII get to submandibular?

A

runs with V3…flesh this out more

31
Q

name the 4 parasymp ganglion

A

CPOS

CN III uses ciliary ganglion
CN VII uses pterygo and submandibular
CN IX uses otic ganglion

32
Q

Which ganglion does the parotid?

A

Otic ganglion

33
Q

CN V is a taxi for?

A

CN III, CN IX, and VII (GVE components)

note: CN V has no GVE components itself

34
Q

How many petrosal nerves are there?

A

Greater, deep, lesser

35
Q

Symp fibers in deep petrosal nerve originate from

A

chain ganglion. Don’t synaps at pterygopalatine ganglion

36
Q

Lacrimal nerve is a branch of

A

CN V1 (sensation of the gland)

CN VII is the one that makes the lacrimal gland cry

37
Q

Do parasympathetics (GVE) round up, or narrow, the lens?

A

Round up

note: they also constrict the pupil

38
Q

Lens is stuck round, and pupil is small. What’s wrong?

A

Parasympathetics are dominating here. Maybe the sympathetics are knocked out.

39
Q

Name a muscle in the eye that has sympathetic innervation.

A

Tarsal muscle (eyelid)

40
Q

Does the nerve that innervates the tarsal muscle synapse at the ciliary ganglion?

A

No! The tarsal muscle has SYMPATHETIC innervation, so it’s nerves synapse at the sympathetic chain ganglion.

41
Q

Is the greater splanchnic nerve sympathetic or parasympathetic?

A

Sympathetic

42
Q

Name one gland that sympathetics command (GVE)…

A

Sweat glands

Remember: hornet’s syndrome

43
Q 
Which of the following are under parasympathetic control:
A. Ciliary muscle
B. Sphincter pupillae
C. Dilator pupillae
D. Tarsal muscle
A

A and B!

High yield.

44
Q

Name two collateral ganglion where CN VII synapse

A

Pterygopalatine ganglion
Submandibular ganglion

(note: poopy shoes on your face)

45
Q

Pair the CPOS ganglia with their respective glands

A

Ciliary: NONE
Pterygopalatine: lacrimal gland
Otic: parotid
Submandibular: submandib. + sublingual

46
Q

SVA: TASTE post 1/3 tongue. CN?

A

CN IX

47
Q

SVA: TASTE ant 2/3 tongue. CN?

A

CN VII (corda tympani)

48
Q

SVE: stylopharyngeous m. CN?

A

CN IX

49
Q

What nerve SENSES increased BP at the carotid body?

A

CN IX.

…signals CN X to slow down heart.
