(both salivary glands)

Question 2

Submandibular ganglion motor nerve/pre-synaptic presympathetics

Answer 2

Chorda Tympani (Facial Nerve, CN VII)

Question 3

Submandibular ganglion sensory root

Answer 3

Lingual nerve (branch of mandibular nerve V3)

Question 4

Answer 4

Middle Cervical Ganglion, external carotid plexus via facial artery

Question 5

Submandibular distribution roots

Answer 5

Lingual nerve (V3) branches to glands

Question 6

location of submandibular ganglion

Answer 6

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

Question 7

Otic ganglion location

Answer 7

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

Auriculotemporal branch of Mandibular Nerve (V3)

Question 12

otic ganglion distribution roots

Answer 12

branches of auriculotemporal nerve (V3)

Question 13

Middle Cervical Ganglion

Answer 13

Sympathetics for otic ganglion and submandibular ganglion

around external carotid artery and branches

Question 14

Ciliary Ganglion location

Answer 14

located in orbit lateral to optic nerve

Question 15

Ciliary ganglion targets

Answer 15

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)

Question 16

Ciliary Ganglion pre-synaptic parasympathetics/ motor root

Answer 16

Oculomotor Nerve (CN III)

Answer 17

Superior Cervical Ganglion via internal carotid plexus through ophthalmic artery

Question 18

Ciliary Ganglion sensory root

Answer 18

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

Question 19

ciliary ganglion distribution root

Answer 19

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

Question 20

pterygopalatine ganglion location

Answer 20

pterygopalatine fossa, hangs off of maxillary nerve (V2)

Question 21

pterygopalatine ganglion targets

Answer 21

Lacrimal gland, nasal/palatal/pharyngeal mucosa

Question 22

pterygopalatine ganglion presynaptic parasympathetics/motor root

Answer 22

greater petrosal nerve, branch of CN VII

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

Question 23

pterygopalatine ganglion postsynaptic sympathetics

Answer 23

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

Question 24

pterygopalatine ganglion sensory root

Answer 24

maxillary nerve

Question 25
