1

branches of 5 and their function

V1 & V2 - sensory only
V3 - sensory and motor

2

name of trigeminal (CNV) branches

V2 - maxillary
V3 - mandibular

3

olfactory nerves are

special sensory

4

oculomotor nerves are

motor & parasympathetic

12

course all cranial nerves take

CNS > intracranial > extra cranial

13

trigeminal connects to CNS where

only cranial nerve to connect to pons

14

15

CN V1 foramina

superior orbital fissure

16

CN V2 foramina

foreamen rotundum

17

CN V3 foramina

foreamen ovale (only one to carry motor fibres)

18

CN V1 supplies where

cornea, conjunctiva, upper eyelid, skin of bridge of nose

19

CN V2 supplies

skin of (coz only sensory): lower eye lid, sides of nose (ala), maxima, upper lip skin/mucosa

20

CN V3 supplies

skin over the mandible and temporomandibular joint (apart from the angle of the mandible – supplied by C2,3 spinal nerves)

28

facial never innervates which structures

sublingual and submandibular glands, muscles of facial expression, anterior 2/3 taste buds

29

glossopharyngeal nerve connects to CNS where

medulla

30

glossopharyngeal nerve passed through which foraminae

jugular
