Cranial Autonomics Flashcards
What are the cranial nerves?
Oh: olfactory
Oh: optic
Oh: oculomotor
To: trochlear
Touch: trigeminal
And: Abducens
Feel: facial
Vagina: vestibulochochlear
God: glossopharyngeal
Vaginas: Vagus
Are: Accessory
Hot!: Hypoglosseal

What are the 4 autonomic (Visceral motorr) nuclei and what are the nerves in them?
Edinger-Westphal: 3 (occulomotor)
Superior salivatory nucleus: 7 (facial)
Inferior Salivatory nucleus: 9 (glossopharyngeal
Dorsal vagal nucleus: 10 (vagus)
What are the 8 cranial holes to know?

cribiform plate
optic canal
superior orbital fissure
foramen rotundum
foramen ovale
internal acoustic meatis
jugular foramen
hypoglossal canal
What nerve goes through the cribiform plate?
1: olfactory
What nerve goes through the optic canal?
2 = optic n
What nerve goes through the superior orbital fissure?
3, 4, V1, 6
(occulomotor, trochlear, trigeminal, abducens)
What nerve go through foramen rotundum?
V2 (maxillary n)
What nerve goes through foramen ovale?
V3 (mandibular N)
What nerves go through the internal acoustic meatis?
7 and 8
(facial n, vestibulochochlear n)
What nerves go through the jugular foramen?
9, 10, 11
(glossopharyngeal, Vagus, accessory)
What nerve goes through the hypoglossal canal?
12
(hypoglossal)
How do sympathetics run in the head?
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*
How do parasympathetics synapse on their way to the head?
fibers arise from the brain stem –> synapse at 4 ganglia in the head:
ciliary
pterygopalantine
otic
submandibular
How are preganglionic PS fibers carried?
Postganglionic?
Pre: by cranial nerves 3, 7, 9, and 10
Post: piggy back on a branch of the trigeminal to arrive at structure they innervate
How does the deep petrosal n arise and run?
post-ganglionic SNS from syperior cervical ganglion –> internal carotid plexus –> now deep petrosal n (CN 7) –> pterygoid canal –> pterygopalatine ganglion
What are the 3 sympathetic plexuses to the head?
internal carotid a plexus
facial a plexus
external carotid a plexus
What is Horner’s syndrome?
Have you met PAM Horner?
Ptosis
Anhidrosis
Miosis
absence of sympathetically stimulated fxns on ipsilateral side of the head
What are the 3 branches of the trigeminal N (CN 5)?
opthalmic n
maxillary n
mandibular n
What are the 2 parts of the opthalmic n that are piggy backed by PNS?
lacrimal n
short ciliary ns
What are the 4 parts of V2 piggy backed by PNS?
zygomatic
nasociliary
greater and lesser palatine
posterior superior nasal
What are the 2 parts of V3 piggy backed by PNS?
lingual
auriculotemporal
What do the PNS motor fibers following CN 3 (oculomotor n) do?
edinger-westphal nucleus –> to ciliary ganglion –> short ciliary nerves –> innervate constrictor pupilae and ciliary muscles
What do PNS following facial nerve (CN 7) do?
superior salivatory nucleus –> pterygopalatine and submandibular ganglia –> lacrimal, submandibular, and sublingual glands; oral, nasal, pharyngeal mucosal glands
