Q

What are the cranial nerves?

A

Oh: olfactory

Oh: optic

Oh: oculomotor

To: trochlear

Touch: trigeminal

And: Abducens

Feel: facial

Vagina: vestibulochochlear

God: glossopharyngeal

Vaginas: Vagus

Are: Accessory

Hot!: Hypoglosseal

2
Q

What is the type of each cranial nerve?

A

Some

Say

Money

Matters

But

My

Brother

Says

Big

Business

Matters

Most

3
Q

What are the 4 autonomic (Visceral motorr) nuclei and what are the nerves in them?

A

Edinger-Westphal: 3 (occulomotor)

Superior salivatory nucleus: 7 (facial)

Inferior Salivatory nucleus: 9 (glossopharyngeal

Dorsal vagal nucleus: 10 (vagus)

4
Q

What are the 8 cranial holes to know?

A

Cunts Order Sex Rates Over In Jewish Hell

cribiform plate

optic canal

superior orbital fissure

foramen rotundum

foramen ovale

internal acoustic meatis

jugular foramen

hypoglossal canal

5
Q

What nerve goes through the cribiform plate?

A

1: olfactory

6
Q

What nerve goes through the optic canal?

A

2 = optic n

7
Q

What nerve goes through the superior orbital fissure?

A

3, 4, V1, 6

(occulomotor, trochlear, trigeminal, abducens)

8
Q

What nerve go through foramen rotundum?

A

V2 (maxillary n)

9
Q

What nerve goes through foramen ovale?

A

V3 (mandibular N)

10
Q

What nerves go through the internal acoustic meatis?

A

7 and 8

(facial n, vestibulochochlear n)

11
Q

What nerves go through the jugular foramen?

A

9, 10, 11

(glossopharyngeal, Vagus, accessory)

12
Q

What nerve goes through the hypoglossal canal?

A

12

(hypoglossal)

13
Q

How do sympathetics run in the head?

A

all sympathetic fibers are postganglionic arising from the superior cervical ganglion of the sympathetic trunk

travel on vessels to structures

*deep petrosal is only named SNS nerve to know*

14
Q

How do parasympathetics synapse on their way to the head?

A

fibers arise from the brain stem –> synapse at 4 ganglia in the head:

ciliary

pterygopalantine

otic

submandibular

15
Q

How are preganglionic PS fibers carried?

Postganglionic?

A

Pre: by cranial nerves 3, 7, 9, and 10

Post: piggy back on a branch of the trigeminal to arrive at structure they innervate

16
Q

How does the deep petrosal n arise and run?

A

post-ganglionic SNS from syperior cervical ganglion –> internal carotid plexus –> now deep petrosal n (CN 7) –> pterygoid canal –> pterygopalatine ganglion

17
Q

What are the 3 sympathetic plexuses to the head?

A

internal carotid a plexus

facial a plexus

external carotid a plexus

18
Q

What is Horner’s syndrome?

A

Have you met PAM Horner?

Ptosis

Anhidrosis

Miosis

absence of sympathetically stimulated fxns on ipsilateral side of the head

19
Q

What are the 3 branches of the trigeminal N (CN 5)?

A

opthalmic n

maxillary n

mandibular n

20
Q

What are the 2 parts of the opthalmic n that are piggy backed by PNS?

A

lacrimal n

short ciliary ns

21
Q

What are the 4 parts of V2 piggy backed by PNS?

A

zygomatic

nasociliary

greater and lesser palatine

posterior superior nasal

22
Q

What are the 2 parts of V3 piggy backed by PNS?

A

lingual

auriculotemporal

23
Q

What do the PNS motor fibers following CN 3 (oculomotor n) do?

A

edinger-westphal nucleus –> to ciliary ganglion –> short ciliary nerves –> innervate constrictor pupilae and ciliary muscles

24
Q

What do PNS following facial nerve (CN 7) do?

A

superior salivatory nucleus –> pterygopalatine and submandibular ganglia –> lacrimal, submandibular, and sublingual glands; oral, nasal, pharyngeal mucosal glands

25
Q

How does the vagus n run and what does it innervate in the head and neck?

A

dorsal vagal motor nucleus and nucleus ambiguus –> sm m and glands of pharynx, and larynx
