Cranial autonomics

Question 1

what classification refers to PNS or SNS (autonomic) nervation

Answer 1

GVE (visceromotor function)

Question 2

what are the CN that run with PNS

Answer 2

3, 7, 9, 10

Question 3

what are the nuclei associated with 3, 7, 9, 10

Answer 3

3- Edinger-Westphal
7- superior salivatory
9- inferior salivatory
10-Dorsal vagus

• ESID [ east side is dope ]

Question 4

what does SLUDD stand for

Answer 4

salivation, lacrimation, urination, defection, digestion

PNS from CNs function

Question 5

what nerves exit/enter the superior orbital fissure

Answer 5

3, 4, 5 (V1), 6

*3-6

Question 6

what nerve exits the foramen rotundum

Answer 6

5 (v2)

Question 7

what nerve exits the foramen ovale

Answer 7

5 (v3)

Question 8

what nerves exit the internal acoustic meatus

Answer 8

7-8

Question 9

what is the SNS of concern ? where does it synapse

Answer 9

deep petrosal N.
synapses in the superior cervical ganglion
-joins greater petrosal N. of C7 and goes to blood vessels and sweat glands of nasal area

Question 10

all postganglionic PNS fiber piggy back on ___ nerve to arrive at their structure

Answer 10

trigeminal N.

Question 11

what is Horners syndrome

Answer 11

-many causes (like extra ribs, etc)
-causes absence of SNS functions to same side
-PAM HORNER (ptosis, anhidrosis, miosis)
miosus= pupil constricting
anihidrosis= no sweating

Question 12

what branches of V1 piggy back PNS

Answer 12

1. lacrimal n.s

2. short ciliary n.s [from nasociliary] (to ciliary muscles and sphincter papillae)

Question 13

what branches of V2 piggy backs PNS

Answer 13

1. zygomatic goes to lacrimal gland
2. greater and lesser palatine goes to hard/soft palate
3. posterior superior nasal goes to nasal cavity

Question 14

what branches of V3 does PNS piggy back

Answer 14

1. lingual N. (submandibular/sublingual salivary glands)

2. auriculotemporal (to parotid gland)

Question 15

what are the ganglions associated with 3, 7, 9, 10 and V1, V2, V3

Answer 15

3- ciliary (v1)
7- pterygopalatine (v2) and submandibular (v3)
9-otic
10-none

Question 16

path of CN 3 PNS division

Answer 16

edinger westphal nucleus to ciliary ganglion to innervate constrictor pupillae M . and ciliary muscles
(from eye accommodation) joining V1 short ciliary nerves

Question 17

what nerves run in the cavernous sinus

Answer 17

ophthalmic N. (v1)
carotid plexus
oculomotor N. (CN 3)

3, 4, 5, 6

Question 18

chorda tympani piggy backs on ____

Answer 18

lingual N. to go to submandibular and sublingual glands

Question 19

desribe the pathway to the lacrimal glands

Answer 19

CN 7 gives off branch called greater petrosal N. at the geniculate ganglion. it then joins deep personal N. are the foramen lucerum and makes the nerve of the pterygoid canal. it travels through the canal into the pterygopalatine fossa where it synapses in pterygopalatine ganglion and innervate lacrimal glands with zygomatic branch of V2 and lacrimal nerve of V1

Question 20

describe the pathway to submandibular and sublingual glands

Answer 20

CN7 gives off a branch called the chorda tympani just before the stylomastoid foramen. it crosses the tympanic cavity and passes through the petrotympanic fissures to join the lingual N. (v3) in infratemporal fossa. then the PNS synapses in the submandibular ganglion and follows arteries to the glands

Question 21

describe the pathway to the parotid gland

Answer 21

CN 9 gives off the tympanic nerve which exits the jugular foramen and enters the middle ear via tympanic canaliculus where it forms the tympanic plexus. lesser petrosal nerves arise from the plexus and penetrate roof of tympanic cavity to enter middle cranial fossa and leave through the foramen ovale. PNS synapse in otic ganglion and go to parotid with branches of auriculotoemporal (v3)

Question 22

what nerves supply SVE fibers (to motor innervation to muscles from pharyngeal arches ) and what arch do they correspond to ?

Answer 22

5- trigeminal - arch 1
7- facial - arch 2
9- glossopharyngeal - arch 3
10- vagus- arch 4 and 6
