Back 3

geniculate ganglion

Front 4

how does sympathetic innervation reach the head?

Back 4

fibers are distributed along the blood vessels

Front 5

miosis (constricted pupil), ptosis (drooping) eyelid, anhydrosis of facial skin, flushing of facial skin

Back 5

Horners syndrome

Front 6

which 2 nerves join to form the nerve of the pterygoid canal?

Back 6

deep petrosal (postganglionic sympathetics to pterygopalatine ganglion; innervates blood vessels and mucous glands of hte head and neck)

and

great petrosal (parasympathetic to pterygopalatine ganglion; innervates lacrimal gland; cell bodies in superior salivatory nucleus of VII)

Front 7

most sympathetic postganglionic fibers have their cell bodies in the...

Back 7

superior cervical ganglion

Front 8

Trigeminal nerve V is a carrier for which fibers?

Back 8

parasympathetic fibers of the cranial nerves

Front 9

what nerve passes through the cavernous sinus?

Back 9

mandibular division of trigeminal (V3); there is no air in the cavernous sinus

Front 10

lesser petrosal nerve carries preganglionic parasympathetic fibers to what ganglion?

Back 10

otic ganglion; innervates parotid gland

Front 11

lacrimal canaliculi

Back 11

passes tears from the conjunctival sac to the lacrimal sac

Front 12

origin and insertion of the sphenomandibular ligament

Back 12

originates at spine of sphenoid bone and inserts into the lingula of the mandible

Front 13

where is the mandibular fossa

Back 13

on the inferior surface of the squamous part of the temporal bone

Front 14

what are the 2 inner ear muscles

Back 14

stapedius- stabilizes the stapes; innervated by VII

tensor tympani- pulls on malleus and tenses the eardrum so vibration is decreased and the amplitude of sound is decreased; innervated by V

Front 15

chorda tympani is what?

Back 15

nerve that passes between the superior portion of the medial surface of the tympanic membrane and the root of the handle of the malleus

it is a branch of VII

provides special sensory fibers for taste to the anterior 2/3 of the tongue, and presynaptic parasympathetic fibers to the submandibular ganglion to provide secretomotor innervation to the sublingual and submandibular glands

Back 17

part of the middle layer o the eyeball

Front 18

pathway of blood to the eyeball

Back 18

internal carotid to

ophthalmic artery to

central artery of retina (pierces optic nerve)
