1
Q

parasympathetic fibers leave brain with in cranial nerves: ___

A

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

2
Q

oculomotor (CN III):

nerves conveying parasympathetic fibers (preganglionic) to peripheral prasympathetic ganglia

A

branches of CN III within the orbit

3
Q

facial (CN VII):

nerves conveying parasympathetic fibers (preganglionic) to peripheral prasympathetic ganglia

A

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
Q

glossopharyngeal (CN IX):

nerves conveying parasympathetic fibers (preganglionic) to peripheral prasympathetic ganglia

A

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

5
Q

oculomotor (CN III):

peripheral parasympathetic ganglia

A

ciliary

6
Q

facial (CN VII):
greater petrosal nerve:

peripheral parasympathetic ganglia

A

pterygopalatine

7
Q

facial (CN VII):
chorda tympani:

peripheral parasympathetic ganglia

A

submandibular

8
Q

glossopharyngeal (CN IX):

peripheral parasympathetic ganglia

A

otic

9
Q

oculomotor (CN III):

divisions of CN V (from which the ganglia hang)

A

nasociliary nerve (branch of opthalmic)

10
Q

facial (CN VII):
greater petrosal nerve:

divisions of CN V (from which the ganglia hang)

A

maxillary

11
Q

facial (CN VII):
chorda tympani:

divisions of CN V (from which the ganglia hang)

A

lingual nerve (branch of mandibular)

12
Q

glossopharyngeal (CN IX):

divisions of CN V (from which the ganglia hang)

A

mandibular

13
Q

oculomotor (CN III):

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

A

short ciliary nerves (branches of nasociliary nerve)

14
Q

facial (CN VII):
greater petrosal nerve:

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

A

branch of maxillary division that communicates w/ lacrimal nerve

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

15
Q

facial (CN VII):
chorda tympani:

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

A

independent fibers to the submandibular gland & sublingual gland

some fibers rejoin the lingual nerve to reach the sublingual gland

16
Q

glossopharyngeal (CN IX):

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

A

auriculotemporal nerve

17
Q

oculomotor (CN III):

target(s)

A

sphincter pupillae

ciliary muscle

18
Q

facial (CN VII):
greater petrosal nerve:

target(s)

A

lacrimal gland

mucous glands of nose, hard & soft palates

19
Q

facial (CN VII):
chorda tympani:

target(s)

A

independent fibers to the submandibular gland & sublingual gland

some fibers rejoin the lingual nerve to reach the sublingual gland

20
Q

glossopharyngeal (CN IX):

target(s)

A

parotid gland
