1

What type of fibers does the glossopharyngeal nerve carry?

Motor, sensory, autonomic; therefore it is mixed!

2

Where does the glossopharyngeal carry motor information to

The stylopharyngeus

3

Where does the glossopharyngeal carry sensory information from

From the pharynx

4

Where does the glossopharyngeal carry taste information from

The posterior tongue

5

Where does the glossopharyngeal carry parasympathetic information to

Leading ultimately to the parotid and other glands

6

Where do the cell bodies for motor fibers carried in the glossopharyngeal arise from

They are located in the superior part of the nucleus ambiguus

7

Where do preganglionic parasympathetic fibers arise from in the glossopharyngeal nerve

The inferior salivary nucleus

8

Where are afferent sensory fibers terminated with the glossopharyngeal

In the solitary nucleus

9

What are the two ganglia associated with the glossopharyngeal

Superior and inferior ganglia

10

Which peripheral ganglion is smaller and usually thought as a separate part

The superior ganglion

11

General sensory information carried in glossopharyngeal is from where

The nasopharynx, oropharynx, and portion of the tongue posterior to the sulcus terminalis, uvula, and palatine tonsils

12

General sensation from what cavity is also carried in a branch of the glossopharyngeal

Tympanic cavity

13

Where are the cell bodies located for general sensory info of the glossopharyngeal

The inferior ganglion where information is then conveyed to the CNS and fibers synapse in the spinal nucleus of trigeminal nerve

14

Taste information from the tongue posterior to the sulcus terminalis is carried by neurons from where?

The inferior ganglion

15

Where is taste information carried from in the glossopharyngeal

Tongue posterior to the sulcus terminalis

16

Axons carrying taste information have cells that synapse where

Superior portion of the solitary nucleus

17

Cells carrying visceral afferent information in the glossopharyngeal from where

Carotid sinus and carotid body

18

Incoming visceral afferent information from the inferior ganglion synapse where?

Lower part of solitary nucleus

19

What does the nucleus ambiguus contribute to three cranial nerves and what are those cranial nerves

Lower motor neurons to CN IX, X, XI

20

Axons from the lower motor neurons from nucleus ambiguus that are carried in glossopharyngeal will innervate what muscle

Stylopharyngeus

21

What gives rise to preganglionic parasympathetic axons carried in the glossopharyngeal

The inferior salivary nucleus

22

Where do preganglionic parasympathetic fibers in the glossopharyngeal nerve synaps

The otic ganglion

23

Postganglionic fibers after synapsing in the otic ganglion supply what?

Parotid glands, buccal glands, and inferior labial glands

24

What is the A.O. Of the glossopharyngeal nerve

Lateral aspect of the superior aspect of the MO

25

Where does the glossopharyngeal exit the skull

Via the jugular foramen

26

Where is the superior ganglion for the glossopharyngeal nerve located

Inside the cranium

27

Where is the inferior ganglion for the glossopharyngeal nerve located

Beyond the jugular foramen outside the cranium

28

What is another name for the inferior ganglion of the glossopharyngeal nerve

The petrosal ganglion

29

Where does the tympanic nerve arise from?

The inferior ganglion

30

What does the tympanic branch carry

Preganglionic parasympathetic fibers and sensory
