Flashcards in Parasympathetic Fibers in the Head & Neck Deck (20):
1

parasympathetic fibers leave brain with in cranial nerves: ___

oculomotor (III)
facial (VII)
glossopharyngeal (IX)

2

oculomotor (CN III):

nerves conveying parasympathetic fibers (preganglionic) to peripheral prasympathetic ganglia

branches of CN III within the orbit

3

facial (CN VII):

nerves conveying parasympathetic fibers (preganglionic) to peripheral prasympathetic ganglia

greater petrosal nerve (branch of CN VII) & its continuation as the nerve of pterygoid canal (the latter nerve also contains sympathetic fibers)

chorda tympani

4

glossopharyngeal (CN IX):

nerves conveying parasympathetic fibers (preganglionic) to peripheral prasympathetic ganglia

tympanic nerve (branch of CN IX) & its continuation as the lesser petrosal nerve

5

oculomotor (CN III):

peripheral parasympathetic ganglia

ciliary

6

facial (CN VII):
greater petrosal nerve:

peripheral parasympathetic ganglia

pterygopalatine

7

facial (CN VII):
chorda tympani:

peripheral parasympathetic ganglia

submandibular

8

glossopharyngeal (CN IX):

peripheral parasympathetic ganglia

otic

9

oculomotor (CN III):

divisions of CN V (from which the ganglia hang)

nasociliary nerve (branch of opthalmic)

10

facial (CN VII):
greater petrosal nerve:

divisions of CN V (from which the ganglia hang)

maxillary

11

facial (CN VII):
chorda tympani:

divisions of CN V (from which the ganglia hang)

lingual nerve (branch of mandibular)

12

glossopharyngeal (CN IX):

divisions of CN V (from which the ganglia hang)

mandibular

13

oculomotor (CN III):

nerves conveying parasympathetic fibers (postganglionic) to target(s)

short ciliary nerves (branches of nasociliary nerve)

14

facial (CN VII):
greater petrosal nerve:

nerves conveying parasympathetic fibers (postganglionic) to target(s)

branch of maxillary division that communicates w/ lacrimal nerve

branches of maxillary division supplying the nose, hard & soft palates

15

facial (CN VII):
chorda tympani:

nerves conveying parasympathetic fibers (postganglionic) to target(s)

independent fibers to the submandibular gland & sublingual gland

some fibers rejoin the lingual nerve to reach the sublingual gland

16

glossopharyngeal (CN IX):

nerves conveying parasympathetic fibers (postganglionic) to target(s)

auriculotemporal nerve

17

oculomotor (CN III):

target(s)

sphincter pupillae

ciliary muscle

18

facial (CN VII):
greater petrosal nerve:

target(s)

lacrimal gland

mucous glands of nose, hard & soft palates

19

facial (CN VII):
chorda tympani:

target(s)

independent fibers to the submandibular gland & sublingual gland

some fibers rejoin the lingual nerve to reach the sublingual gland

20

glossopharyngeal (CN IX):

target(s)

parotid gland
