24
Q

two branches of cranial nerves that join branches of mandibular nerve

A
  1. chorda tympani

2. lesser petrosal n

25
Q

chorda tympani is a branch of __ and joins with ___

A

branch of facial n, joins with lingual n

26
Q

lesser petrosal n is a branch of __ and joins with __

A

branch of glossopharyngeal n, joins with auriculotemporal n

27
Q

taste and sensory info to anterior 2/3 of tongue

A
  • taste: chorda tympani

- sensory: lingual n

28
Q

parasymp fibers in chorda tympani n travel with lingual n to floor of the mouth to

A

synapse within the submandibular ganglion

29
Q

after synapsing with submand ganglion, postganglionic parasympathetic fibers supply

A
  • submandibular and sublingual glands

- minor glands of floor of the mouth

30
Q

otic ganglion receives fibers from

A
  • sensory fibers
  • symp fibers
  • parasymp fibers
31
Q

sensory fibers of otic ganglion

A
  • arise from the stem of CN V3

- pass through ganglion WITHOUT synapsing

32
Q

sympathetic fibers of otic ganglion

A
  • arise from perivascular plexus of middle meningeal a

- pass through ganglion WITHOUT synapsing

33
Q

parasymp fibers of otic ganglion

A
  • arise from route originating from lesser petrosal n (CN 9)

- THEY DO SYNAPSE in ganglion

34
Q

parasymp pathway of otic ganglion
