Flashcards in Autonomic Ganglion of head and neck Deck (26):
1

Submandibular Ganglion Targets

Submandibular Gland
Sublinguinal Gland
(both salivary glands)

2

Submandibular ganglion motor nerve/pre-synaptic presympathetics

Chorda Tympani (Facial Nerve, CN VII)

3

Submandibular ganglion sensory root

Lingual nerve (branch of mandibular nerve V3)

4

Submandibular ganglion post-synaptic sympathetics

Middle Cervical Ganglion, external carotid plexus via facial artery

5

Submandibular distribution roots

Lingual nerve (V3) branches to glands

6

location of submandibular ganglion

off of lingual nerve (V3), superior to sub. mandibular gland

7

Otic ganglion location

located immediately below foramen ovale, where Mandibular Nerve exits skull. Suspended off of mandibular nerve.
Mandibular Nerve --> V3

8

Otic ganglion targets

Parotid gland
parOTIC

9

Otic ganglion pre-synaptic parasympathetics/motor root

Lesser Petrosal Nerve (branch of CN IX)

10

Otic ganglion sympathetics

Middle Cervical ganglion, external carotid via maxillary artery, middle meningeal artery

11

otic ganglion sensory root

Auriculotemporal branch of Mandibular Nerve (V3)

12

otic ganglion distribution roots

branches of auriculotemporal nerve (V3)

13

Middle Cervical Ganglion

Sympathetics for otic ganglion and submandibular ganglion
around external carotid artery and branches

14

Ciliary Ganglion location

located in orbit lateral to optic nerve

15

Ciliary ganglion targets

pupil constrictors and dilators, sensory for cornea.
parasympathetic --> constrict pupils
sympathetic --> dilate pupils (fear response)
Contract superior tarsal muscle (keep eyelids open after they have been opened)

16

Ciliary Ganglion pre-synaptic parasympathetics/ motor root

Oculomotor Nerve (CN III)

17

Ciliary Ganglion post-synaptic sympathetics

Superior Cervical Ganglion via internal carotid plexus through ophthalmic artery

18

Ciliary Ganglion sensory root

nasociliary nerve, branch of ophthalmic nerve branch of trigeminal (CN V)

19

ciliary ganglion distribution root

long and short ciliary nerves (branches of nasociliary CN V1)
long - pupil dilators (sympathetic)
short - sensory to cornea, pupil constrictors (parasympathetic)

20

pterygopalatine ganglion location

pterygopalatine fossa, hangs off of maxillary nerve (V2)

21

pterygopalatine ganglion targets

Lacrimal gland, nasal/palatal/pharyngeal mucosa

22

pterygopalatine ganglion presynaptic parasympathetics/motor root

greater petrosal nerve, branch of CN VII
turns into vidian nerve when it joins deep petrosal nerve(sympathetics) in pterygoid canal

23

pterygopalatine ganglion postsynaptic sympathetics

deep petrosal nerve turns into vidian nerve when it joins great petrosal nerve(parasympathetic) in pterygoid canal

24

pterygopalatine ganglion sensory root

maxillary nerve

25

pterygopalatine ganglion distribution root

1. zygomatic nerve (branch of maxillary nerve V2) turns into zygomaticotemporal nerve (V2) which communicates with lacrimal nerve (V1) which leads to lacrimal gland
2. nasopalatine nerve (V2)
3. Greater and Lesser palatine nerve (V2)
4. Pharyngeal nerve (V2)

26

superior cervical ganglion

supplies ciliary and pterygopalatine ganglion
around internal carotid
