Sensory Function: smell
| Name the nerve
Olfactory
26
Sensory Function: vision; afferents for pupillary and accommodation reflexes
(Name the nerve)
Optic
27
Motor Function: moves eye up, down, medially; raises upper eyelid; efferent for VOR
(Name the nerve)
Oculomotor
28
Parasympathetic Efferent Function: constricts pupil; adjusts the shape of the lens of the eye; efferent for pupillary and accommodation reflexes
(Name the nerve)
Oculomotor
29
Motor Function: moves eye medially and down; efferent for VOR
(Name the nerve)
Trochlear
30
Sensory Function: somatosensation from the face, TMJ; afferent for corneal reflex
(Name the nerve)
Trigeminal
31
Motor Function: chewing
| Name the nerve
Trigeminal (V3)
32
Motor Function: abducts eye; efferent for VOR
| Name the nerve
Abducens
33
Motor Function: facial expression, closes eye, protects hearing; efferent for corneal reflex
(Name the nerve)
Facial
34
Sensory Function: taste
| Name the nerve
Facial
35
Parasympathetic Efferent Function: tears, salivation
| Name the nerve
Facial
36
Sensory Function: senses head position relative to gravity and movement; afferent for VOR; hearing
(Name the nerve)
Vestibulocochlear
37
Sensory Function: sensation from pharynx, posterior tongue, middle ear; afferent for gag and swallowing reflexes
(Name the nerve)
Glossopharyngeal
38
Motor Function: constricts pharynx
| Name the nerve
Glossopharyngeal
39
Visceral Afferent Function: taste; blood pressure and chemistry from carotid artery
(Name the nerve)
Glossopharyngeal
40
Parasympathetic Efferent Function: salivation
| Name the nerve
Glossopharyngeal
41
Sensory Function: sensation from pharynx, larynx, skin in external ear canal
(Name the nerve)
Vagus
42
Motor Function: regulates swallowing and speech; efferent for gag and swallowing reflexes
(Name the nerve)
Vagus
43
Visceral Afferent Function: afferents from heart, lungs, trachea, bronchi, larynx, pharynx, GI system, liver, pancreas
(Name the nerve)
Vagus
44
Parasympathetic Efferent Function: regulates viscera
| Name the nerve
Vagus
45
Motor Function: elevates shoulders, turns head
| Name the nerve
Spinal Accessory
46
Motor Function: moves tongue
| Name the nerve
Hypoglossal
47
Abnormal response: lack of blinking in response to touch of cornea
(Name the nerve involved)
Trigeminal (V1)
| Afferent limb of the blink reflex
48
Abnormal response: deviation of jaw toward involved side when mouth is opened
(Name the nerve involved)
Trigeminal (V3)
49
Abnormal response: drooping of the face, inability to close the eye
(Name the nerve involved)
Facial
50
Abnormal response: conductive deafness (transmission of vibrations prevented in outer or middle ear)
(Name the nerve involved)
Deafness is due to peripheral problem that does not involve neural transmission
51
Abnormal response: sensorineural deafness
| Name the nerve involved

52
Abnormal response: loss of gag reflex
| Name the nerve involved
Glossopharyngeal (afferent limb), Vagus (efferent limb)
53
Abnormal response: asymmetric elevation of palate
| Name the nerve involved
Glossopharyngeal (afferent), Vagus (efferent)
54
Abnormal response: tongue deviates to one side when protruded
(Name the nerve involved)
Hypoglossal
