Cranial Autonomics

Question 1

What type of fibers do we are about with ANS of the head?

Answer 1

GVE

Question 2

What does the SNS do in the head?

Answer 2

Fibers are post-ganglionic and from the superior cervical ganglion and travel on vessels to reach their target.

Question 3

PSNS overview in the head

Answer 3

Fibers are pre-ganglionic from nuclei in the brain and synapse at one of 4 ganglia and piggy back on CN V.

Question 4

CNs that carry PSNS

Answer 4

CNs 3, 7, 9, 10

Question 5

Horner’s syndrome

Answer 5

SNS overactivity.

Sx: ptosis, anhidrosis, miosis.

Question 6

CN thru cribiform plate

Answer 6

CN I

Question 7

CN thru Optic canal

Answer 7

CN II

Question 8

CNs thru superior orbital fissure

Answer 8

CN III, IV, V (V1), VI

Question 9

CNs thru internal auditory meatus

Answer 9

CN VII, VIII

Question 10

CNs thru jugular foramen

Answer 10

CN XI, X, XI

Question 11

CN thru hypoglossal foramen

Answer 11

CN XII

Question 12

What nerves from the ophthalmic n. does PSNS travel on?

Answer 12

Lacrimal n. –> lacrimal glands

Short ciliary n. –> ciliary ms. of the eye

Question 13

What nerves from the maxillary n. does PSNS travel on?

Answer 13

Zygomatic n. –> lacrimal glands
Greater and Lesser palatine n. –> palate mucosa
Posterior superior nasal n. –> posterior superior part of nasal cavity.

Question 14

What nerves from the mandibular n. does PSNS travel on?

Answer 14

Lingual n. –> submandibular and sublingual glands.

Auriculotemporal n. –> parotid glands

Question 15

CN III nucleus and ganglion

Answer 15

CN III

Edinger-Westphal nucleus –> ciliary ganglion

Question 16

CN VII nucleus and ganglion

Answer 16

CN VII

Superior salivary nucleus –> pterygopalatine and submandibular ganglia

Question 17

CN IX nucleus and ganglion

Answer 17

CN IX

Inferior salivary nucleus –> otic ganglion

Question 18

V1 goes to what ganglion ?

Answer 18

Ciliary ganglion

Question 19

V2 goes to what ganglia?

Answer 19

Pterygopalatine and submandibular ganglia

Question 20

V3 goes to what ganglion?

Answer 20

Otic ganglion

Question 21

How do we get PSNS to the lacrimal gland?

Answer 21

Greater petrosal n. (from facial n.) meets with deep petrosal n. (SNS) become the N of the pterygoid canal and synapse in the pterygopalatine ganglion with lacrimal n. and zygomatic n. to innervate the lacrimal gland.

Question 22

How do we get PSNS to the sublingual and submandibular glands?

Answer 22

Chorda tympani n. (from facial n.) meets with lingual n. (from V3) and synapses in the submandibular ganglion and travels on vessels to the sublingual and submandibular glands.

Question 23

How do we get PSNS to the parotid gland?

Answer 23

Lesser petrosal n. (from glossopharyngeal n.) and synapses in the otic ganglion with auriculotemporal n. to innervate the parotid gland.
