cranial nerves 3-6

Question 1

oculomotor nucleus is which type of nerve

Answer 1

somatomotor

Question 2

the accessory oculomotor nucleus

Answer 2

parasympathetic ( general visceromotor)

Question 3

the oculomotor nerve has two branches?

Answer 3

superior and inferior

Question 4

the superior branch supplies what?

Answer 4

the superior rectus muscle

levator palpebrae superioris

Question 5

the inferior branch of the oculomotor supplies what?

Answer 5

medial rectus
inferior rectus
inferior oblique

Question 6

the accessory oculomotor nerve first goes where and then supplies what?

Answer 6

the preganglionic fiber goes to the ciliary ganglion

from there the secondary fiber goes to the ciliary muscle and sphincter pupilae

Question 7

the trochlear nerve is what type?

Answer 7

general somatomotor

Question 8

the trochlear nerve supplies what?

Answer 8

superior oblique muscle

Question 9

the trigeminal nerve have 3 branches

Answer 9

ophthalmic, maxillary, madibular

Question 10

the ophthalmic first divides into 3 main branches

Answer 10

lacrimal
frontal
nasociliary

Question 11

the lacrimal nerve supplies what?

Answer 11

skin of the lateral corner of the eye

the lacrimal gland is supplies by a communicating branch from post ganglionic parasymp fibers of the zygomatic

Question 12

frontal nerve has what branches?

Answer 12

supratrochlear

supraorbital

Question 13

the supratrochlear and supraorbital supply what?

Answer 13

in general, forhead, upper eyelid, scalp

supratrochlear - medial upper eyelid, central forehead (glabella), root of nose

supraorbital - thru supraorbital notch for conjuctiva, forehead, upper eyelid, scalp, frontal sinus

Question 14

the nasocilary nerve has which branches?

Answer 14

infratrochlear nerve with the ant and post ethmoidal nerve
long ciliary
communicating

Question 15

the nasocillary branches supplies generally?

Answer 15

eye, nose, eyelid

long ciliary - dialator pupilae, ciliary muscle, iris, cornea
communicating - sensory fibers
ethmoidal nerves - nasal mucosae
infratrochlear - skin of eyelid, root of nose

Question 16

the maxillary nerve

Answer 16

ganglionic branches
zygomatic
infraorbital

Question 17

what are the branches of the zygomatic nerve?

Answer 17

zygomaticofacial

zygomaticotemporal

Question 18

zygomaticofacial and zygomaticotemporal supply what?

Answer 18

zygomaticofacial - skin of lateral face and cheekbone

zygomaticotemporal - skin of lateral face to orbit

Question 19

the ganglionic branches have which main branches?

Answer 19

nasal branches, greater palatine, lesser palatine, pharyngeal branches

Question 20

nasal branches are?

Answer 20

posterior superior lateral, posterior superior medial, and scarpa’s

Question 21

the posterior superior lateral, posterior superior medial, and scarpa’s nerve supply what?

Answer 21

posterior superior lateral - nasal lateral septum, sup and middle nasal concha, ethmoidal sinus
posterior superior medial - nasal septum
scarpa’s - thru sphenopalatine foramen, thru incisive foramen for mucous membrane of hard palate

Question 22

the greater palatine nerve has one additional branch called?

Answer 22

posterior inferior nasal branch

Question 23

the greater palatine nerve and posterior inferior nasal branch supply what?

Answer 23

greater palatine: mucosa and glands of hard palate, anterior part of soft palate (post synaptic parasymp and sensory fibers)

post inf nasal nerve - to post inf lateral wall of nasal cavity, may arise independ. of the greater palatine n

Question 24

the lesser palatine nerves supply what? go in which foramen?

Answer 24

usually 2 nerves, they go in lesser palatine foramina.
soft palate mucosa, glands, uvula.
(post synaptic parasymp and sensory fibers)

Question 25

pharyngeal nerve goes where and supplies what?

Answer 25

thru pharyngeal canal (palatovaginal canal) with sensory and parasymp fibers to nasopharynx mucus glands

Question 26

what is the relationship of the pharyngeal nerves (nasal, greater and lesser palatine, pharyngeal) to the pterygopalatine ganglion?

Answer 26

they all pass through the pterygopalatine ggl but DO NOT synapse in it

Question 27

infraorbital nerve has three branches

Answer 27

superior dental plexus:
anterior superior alveolar - incisors, canines
middle superior alveolar - premolars
posterior superior alveolar - maxillary sinus

Question 28

the infraorbital nerve supplies what area?

Answer 28

skin btw lower eyelid and upper lip, eventually give branches that create dental plexus
