Question 1

parasympathetic fibers leave brain with in cranial nerves: ___

Answer 1

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

Question 2

oculomotor (CN III):

nerves conveying parasympathetic fibers (preganglionic) to peripheral prasympathetic ganglia

Answer 2

branches of CN III within the orbit

Question 5

oculomotor (CN III):

peripheral parasympathetic ganglia

Answer 5

ciliary

Question 6

facial (CN VII):
greater petrosal nerve:

peripheral parasympathetic ganglia

Answer 6

pterygopalatine

Question 7

facial (CN VII):
chorda tympani:

peripheral parasympathetic ganglia

Answer 7

submandibular

divisions of CN V (from which the ganglia hang)

Answer 9

nasociliary nerve (branch of opthalmic)

Question 10

facial (CN VII):
greater petrosal nerve:

divisions of CN V (from which the ganglia hang)

Answer 10

maxillary

mandibular

Question 13

oculomotor (CN III):

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

Answer 13

short ciliary nerves (branches of nasociliary nerve)

Question 14

facial (CN VII):
greater petrosal nerve:

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

Answer 14

branch of maxillary division that communicates w/ lacrimal nerve

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

target(s)

Answer 19

independent fibers to the submandibular gland & sublingual gland

some fibers rejoin the lingual nerve to reach the sublingual gland
