Cranial Nerves Flashcards
Cranial nerve 1
Olfactory (smell)
Cranial Nerve 2
Optic (vision)
Cranial Nerve 3
Oculomotor (eye movement)
Cranial Nerve 4
Trochlear (eye movement)
Cranial Nerve 5
Trigeminal (Facial sensation and mastication)
Cranial Nerve 6
Abducens (eye movement)
Cranial Nerve 7
Facial (taste and movement of the face)
Cranial Nerve 8
Vestibulocochlear (hearing and equilibrium)
Cranial Nerve 9
Glossopharyngeal (taste and tongue movement/swallowing)
Cranial Nerve 10
Vagus (parasympathetic regulation of heart, lungs, abdomen; sensory impulses of abdominal viscera, baroreceptors, chemoreceptors, taste buds)
Cranial Nerve 11
Accessory (trapezius and sternocleidomastoid movement)
Cranial Nerve 12
Hypoglossal (tongue movement, swallowing, speech)

what is the clinical test for cranial nerve 1 (olfactory)
sniff aromatic substance, usually vanilla
what is the clinical test for cranial nerve 2 (optic)
eye chart, or testing the point at which the person sees an object/finger moving into the visual field
what is the clinical test for cranial nerve 8 (vestibulocochlear)
hearing checked by air and bone conduction using tuning fork
what is the clinical test for cranial nerve 9 (glossopharyngeal) and 10 (vagus)
speak, cough, position of uvula checked, gag reflex
what is the clinical test for cranial nerve 11 (accesory)
rotate head and shrug shoulders against resistance
what is the clinical test for cranial nerve 12 (hypoglossal)
