Cranial Nerve 1
|
Olfactory: smell reception and interpretation
|
|
Cranial Nerve 2
|
Optic: visual acuity and visual fields
|
|
Cranial Nerve 3
|
Oculomotor: raise eyelids, most extraocular movements, pupillary constriction, change lens shape
|
|
Cranial Nerve 4
|
Trochlear: downward and inward eye movement
|
|
Cranial Nerve 5
|
Trigeminal: jaw opening and clenching, chewing and mastication
|
|
Cranial Nerve 6
|
Abducens: lateral eye movement
|
|
Cranial Nerve 7
|
Facial: movement of facial expression muscles (except jaw), taste (anterior two thirds of tongue)
|
|
Cranial Nerve 8
|
Acoustic: hearing and equilibrium
|
|
Cranial Nerve 9
|
Glossopharyngeal: voluntary muscles for swallowing, taste (posterior one third of tongue)
|
|
Cranial Nerve 10
|
Vagus: voluntary muscles of speech and swallowing
|
|
Cranial Nerve 11
|
Spinal accessory: turn head, shrug shoulders
|
|
Cranial Nerve 12
|
tongue movement for speech and swallowing
|
|
Vertigo
|
patient feels as if room is spinning
|
|
Dizziness
|
patient feels as if they are spinning
|
|
Dysphagia
|
Difficulty swallowing
|
|
Dysphasia/Aphasia
|
impairment of speech/absence of speech
|
|
Test eyes for visual acuity
|
test optic nerve (CN 2) for visual acuity using Snellen's chart
|
|
Test eyes for peripheral vision
|
The presence of peripheral vision indicates function of the optic nerve (CN 2)
|
|
Observe eyes for extraocular movement
|
the oculomotor (CN 3), trochlear (CN 4), and abducens (CN 6) nerves are tested together because they control muscles that provide eye movement.
|
|
Observe eyes for pupillary size, shape, equality, constriction and accommodation
|
Pupils should appear equal, round, and reactive to light and accommodation (PERRLA)
|
|
Evaluate face for movement and sensation
|
evaluate the trigeminal nerve (CN 5) for facial movement and sensation.
|
|
Test hears for hearing
|
evaluate the acoustic nerve (CN 8) for hearing. Assessment of sensorineural hearing loss using the Rinne and Weber's test
|
|
Test the tongue for movement, symmetry, and strength
|
evaluate the hypoglossal nerve (CN 12) by observing movement and symmetry of the tongue.
|
|
Muscles the spinal accessory nerve (CN 11) effects
|
sternocleidomastoid and trapezius
|
|
Why do we test cerebellar function
|
for balance and coordination. Perform Romberg test. Have patient stand up and close eyes. If they take a step that is a positive Romberg test. Negative Romberg test is normal.
|
|
intention tremor
|
an involuntary muscle contraction during a purposeful movement of an extremity is not moving
|
