fxn of I
olfactory- smell
26
fxn of II
optic- vision
27
fxn of III
Occulomotor- Everything in eye except closes, abduct and cry! moves eyes up, down, medially, raise upper eyelid, constrict pupil, adjust lens shape
28
fxn of IV
troclear- moves eyes medially and down simultaneously
29
fxn of V
trigeminal- facial sensation, chewing, TMJ sensation
30
fxn of VI
abducens- abducts eye
31
fxn of VII
facial- ( this nerve lets u enjoy ur double choc. fudge brownie that u treat urself to after u've been sad and cried ur eyes out) facial expression, closes eye, tears, salivation, taste
32
fxn of VIII
vestibulocochlear- sensation of the position of head relative to gravity, head movement sensation, hearing
33
fxn of IX
glossopharyngeal- (taste and swallow food) swallowing, salvation, taste
34
fxn of X
Vagus- (think ur stomach is queasy bc ur about to give a speech at CSM in Vegas, u can taste the bile in ur throat, u swallow hard and start talking) regulates viscera, swallowing, speech, taste
35
fxn of XI
accessory- elevates shoulders, turns head
36
fxn of XII
hypoglossal- (the last piece to speaking and eating) moves tongue
37
which CNs control swallowing
Vagus, glossopharyngeal
38
which CNs do u need for the diff parts of eating?
Trigeminal- chewing and sensation from TMJ
Facial- salivation and taste
glossopharyngeal- swallowing, salivation, taste
Vagus- swallowing, speech, taste
hypoglossal- moves tongue

which CN originates on the diencephalon?
optic (II)
55
which CN originates on the inferior frontal lobe?
olfactory (I)
56
which CN originates on the pons
trigeminal (V)
57
how do u test the olfactory nerve
have pt identify a susbstance by smelling it, isolate each nostril
58
how do u test the optic N
vision chart and pupillary reflex (sensory)
59
how do u tests the oculomotor N?
H test to tract finger, check that eyelids open equally, pupillary reflex (motor portion)
60
how do u test the trochlear N
track finger to look at tip of nose
61
how do u test the trigeminal N
sensation of face, corneal reflex (sensory), masseter reflex
62
how do u test abducens N?
track finger to the side
63
how do u test facial N?
facial expressions, corneal reflex (motor portion)
64
how do u test vestibulocochlear N?
vest. function, hearing
65
how do u test glossopharyngeal N?
gag reflex (sensory portion)
66
how do u test Vagus N?
have pt say "ahh" (look for equal and bilateral soft palate rising), gag reflex (motor component)
67
how do u test the accessory N?
MMT the upper trap and SCM
68
how do u test the hypoglossal N?
have pt stick tongue out, if any probs, tongue will deviate towards the damaged side.
