inability to make a motor plan, as a result of brain dam-
age.
Apraxia
lesions affect the frontal or left parietal lobe, can produce
abnormalities in motor conceptualization, planning, and
execution.
lack of muscle coordination
Ataxia
lesions in the cerebellum lead to disorders in coordination
and balance.
aphasia inability to speak
impairment of language, usually caused by left hemi-
Aphasia-sensory aphasia-Wernicke's aphasia sphere damage either to Broca's area (impairing speak-
ing) or to Wernicke's area (impairing understanding).
the condition resulting from damage to Wernicke's area,
(temporal lobe) causing the affected person to be unable
to understand or produce meaningful language -
Wernicke's aphasia
condition resulting from damage to Broca's area, causing
the affected person to be unable to speak fluently, to
mispronounce words, and to speak haltingly
Broca's aphasia
,Neuro Exam 1 USAHS
Study online at https://quizlet.com/_awzmmj
Controls language expression - an area of the frontal lobe,
Broca's area usually in the left hemisphere, that directs the muscle
movements involved in speech.
Test: Making client smell something pleasant
What is being tested: imbalances in neurotransmitter sys-
CN 1 olfactory tems, -nasal construction, damage to olfactory nerves,
lesions affecting olfactory bulbs
front of brain
Test: Examine both retinas with an ophthalmoscope. thal-
amus - test visual acuity (Snellen chart, or # of fingers),
Test color vision- red desaturation
Test visual fields- report when a finger can be seen moving
Test Visual extinction- how many fingers they see
CN II optic
What is being tested: vision
retinas, damage to the visual cortex, deficits in visual fields
of eyes
front of brain
thalamus - looking up, in, and left to right without moving
head
Test: extraocular movements- looking all directions with-
out moving head, and ask if they see double vision
CN III Oculomotor
What is being tested: abnormalities in muscles or CN
III-oculomotor, IV-trochlear, VI-abducens), deficits of the
brainstem and cortex that control eye movements
midbrain structure
CN IV Trochlear

What is being tested: extraocular movements (eye move-
ments)
-abnormalities in muscles or CN III-oculomotor,
IV-trochlear, VI-abducens), deficits of the brainstem and
cortex that control eye movements
is a midbrain structure - cross-eyes into the nose
pons - - Dull vs light sensation in Ophthalmic (forehead)
Maxillary (Cheek)Mandibular (Jawline)
- Have the patient open and close mouth (feel around the
temporomandibular joint)
-Corneal reflex
-Jaw jerk reflex
CN V Trigeminal
What is being tested: facial sensation and muscles of
mastication

sory nuclei in the brainstem
pons
looking laterally (left and right)
