Anatomy - Cranial Nerves

Front 1

Parasympathetic of CN III

Back 1

Ciliary ganglion to spinchter pupillae and ciliary mm

Front 2

Parasympathetic of CN VII (chorda tympani)

Back 2

via chorda tympani goes to submandibular ganglion and then to submandibular gland and sublingual gland

Front 3

Parasympathetic of CN VII (greater pertrosal N)

Back 3

pterygopalatine ganglion to lacrimal gland and nasal and palatal glands

Front 4

PNS of CN IX

Back 4

Glossopharyngeal to otic ganglion to parotid gland

Front 5

12 cranial nerves and sensory, motor or both

Back 5

OOOTTAFVGVAH
SSMMBMBSBBMM

Front 6

Branches of V1

Back 6

In orbit: frontal (to supratrochlear and supraorbital), lacrimal, nasociliary
Also: infratrochlear and external nasal

Front 7

Branches of V2

Back 7

zygomaticofascial, zygomaticotemporal, infraorbital
NEW: superior alveolar, greater and lesser palatine, nasoopalatine nerve

Front 8

Motor innervation of V3

Back 8

mm of mastication
tensor tympani and palatini
mylohyoid and ANT digastric

Front 9

Motor innervation of CN VII

Back 9

facial expression
stylohyoid
pos digastric
stapedius

Front 10

What CNs exit the superior orbital fissure?

Back 10

V1, III, IV, VI

Front 11

Foramen for CN V

Back 11

V1 = superior orbital fissure
V2 = foramen rotunda
V3 = foramen ovale

Front 12

Where does CN VII exit skull?

Back 12

Runs through internal auditory meatus and exits via stylomastoid foramen

Front 13

what nerves run through the internal auditory canal?

Back 13

VII and VIII

Front 14

What nerves exit via jugular foramen?

Back 14

IX, X, XI

Front 15

2 PNS nerves that branch off facial nerve and where do they go?

Back 15

Greater petrosal - Lacrimal gland
chorda tympani - submandibular and sublingual. Also special sensory for taste - ANT 2/3

Front 16

What are submandibular and sublingual glands innervated by?

Back 16

chorda tympani nerve - which hops on the lingual nerve to go to the submandibular ganglion first and then to the glands

Front 17

innervation of CN IX

Back 17

motor to stylopharyngeus
sensory to pos 1/3
special sensory to pos 1/3

Front 18

how does CN IX eventually innervate parotid gland?

Back 18

lesser petrosal nerve branches off CN IX and goes to otic ganglion. goes to parotid gland on auriculotemporal Nerve

Front 19

How does the greater petrosal nerve (branch of VII) get to lacrimal gland and nasal cavity?

Back 19

Hitches a ride with V2

Front 20

What is CN X motor to and sensory to?

Back 20

MOTOR: muscles of palate (minus tensor veli palatini) and mm of pharynx (minus stylopharyngeus) and mm of larynx
SENSORY: pharynx and larynx (internal branch of sup laryneal n)

Front 21

PNS of CN X

Back 21

Pharynx, larynx, abdominal shiot

Front 22

Fxt of internal and external branches of sup laryngeal n? Recurrent laryngeal n?

Back 22

INT = sensory above vocal folds
EXT = motor to cricothyroid m
Recurrent: motor to other shiot and sensory below vocal fields

Front 23

Stern's rules

Back 23

1. Tensor mm = v3 (tympani and veli palatini)
2. mm of palate = CN X (minus tensor veli palatini)
3. tounge mm = CN XII (minus palatoglossus which is CNX)

Front 24

CNs that are special sensory and to what?

Back 24

1. olfactory N = smell
2. optic N = vision
3. Facial N = taste ANT 2/3 via chorda tympani
4. vestibulocochlear = hearing and balance
5. glossopharyngeal = taste pos 1/3
