EXAMS OF HEALTH SCIENCES
Describe two functions of the meninges. Correct Answer 1.
cushion between the brain & skull with CSF.
2.brings nutrients to the brain & takes away waste products.
Describe two differences between the cerebral hemispheres.
Correct Answer Left hemisphere is responsible for language,
motor, motor planning, & problem solving skills.
Right hemisphere the parietal lobe is larger than the left & the
lateral fissure is longer in the left hemisphere.
Describe the concept of homunculus man as it relates to brain
function. Correct Answer Each part relates to different areas of
the body & their functions. Shows where different parts of the
body receive innervation & shows sources of nerve innervation.
What is the significance of the location on the primary motor
cortex of the site for innervation of the muscles of the oral
mechanism? How can this be helpful diagnostically? Correct
Answer Motor speech issues are associated with cortical
damage. Client has motor speech issues, we should look at other
functions of the frontal lobe to determine other deficits & what else
we need to assess & treat.
What is the significance of the location in the frontal cortex of the
neurons that contribute to oral praxis? How can this be helpful
diagnostically? Correct Answer Planning & programming &
volitional speech movements are also affected. We can also look
& assess & treat these deficits. Complex & skilled movements
occur here.
,Explain what an arteriovenous malformation (AVM) is. What type
of danger does AVM present? Correct Answer AVM is when a
blood vessel ruptures & blood rushes in & destroys brain tissue. It
could also collect outside of the brain & interrupt spaces between
the meninges causing compression of the brain within the skull.
This may lead to death or show effects of the stroke.
Name three main areas of the frontal lobe and the functions with
which they are associated. Correct Answer 1. superior frontal
lobe: complex & skilled movements, reasoning, abstract thinking,
self-monitoring, decision-making, planning, & pragmatic
behaviors. Also executive functioning.
2. lateral frontal lobe: contains Broca's area, anterior language
cortex, controls jaw, lip, tongue, & vocal cord movement which is
important for spoken language.
3. orbital frontal area: attention, impulse control, emotional
control.
Describe three symptoms of frontal lobe deficit of executive
function in the orbital-frontal area. How do symptoms of pathology
in this area differ from pathology in the dorso-lateral area of the
frontal lobe? Correct Answer Deficit in orbital-frontal area:
Impulsive, Distractible, &Poor emotional control.
Deficit in dorso-lateral lobe: Reduced goal-directed behavior,
Decrease in drive, Reduced concrete thinking.
The dorso-lateral lobe damage is more quiet, less initiative.
Write a question you might ask during conversation to a client
who presents with frontal lobe deficit in the orbital frontal area.
How would he respond, given his deficits? How would the client
with deficits in the dorso-lateral area of the frontal lobe respond?
Correct Answer "Would you like to go swimming tomorrow?" He
may respond with "YES!!!!." OR he may become really excited,
unable to control his impulses because he cannot control
emotions or drives. However, a pt with dorso-lateral damage may
,not respond, may stand quietly, or won't make suggestions as to
what to do. This is due to decrease in drive, lack of goal-directed
behavior, and limited language output.
List three areas of function for which the temporal lobe is
responsible. Correct Answer 1. Memory
2. Primary auditory cortex
3. Music processing or environmental sounds
List three areas of function for which the parietal lobe is
responsible. Correct Answer 1. Somatic sensations
2. Perceptions of spatial orientation
3. cognition & memory
List three areas of function for the cerebellum. Correct Answer 1.
Coordinates movements initiated elsewhere.
2. modulates movements initiated elsewhere.
3. Regulates rate, range, direction, & force of movement.
Define contralateral homonymous hemianopsia (define each word
& describe its impact on visual acuity for someone with a left
hemisphere CVA). Name two areas in the brain where pathology
can have this effect. Correct Answer Contralateral= opposite side
of the brain.
homonymous = affecting the same part of the visual field in each
eye.
hemianopsia = blindness over half the field of vision
Two areas= parietal lobe & occipital lobe.
Which type of dysarthria is most commonly seen with aphasia &
why? With what type of aphasia is it more commonly seen?
Correct Answer Unilateral upper motor neuron dysarthria
because it affects muscles of the mouth. It is usually seen in
someone with Broca's aphasia which affects speech.
, What other communication diagnosis often accompanies Broca's
aphasia & why? Correct Answer Apraxia of speech: written
language is normal,poor repetition, poor naming, good
comprehension.
Name two arteries that lead to the circle of willis, & three that
stem from it. Correct Answer Carotid artery & vertebral basiliar
1.) Anterior cerebral artery (ACA)
2.) middle cerebral artery (MCA)
3.) posterior cerebral artery (PCA)
Describe the difference between ischemic & hemorrhagic stroke,
in terms of etiology, pattern of recovery, & prognosis. Correct
Answer Ischemic occurs when the blood supply to the part of the
brain becomes inadequate for the brain cells to function. Pt shows
progress immediately until the condition is stabilized. Language 3
months & Neuro recovery 6 months.
Hemorrhagic strokes occur when a blood vessel ruptures & blood
either rushes through the brain tissue destroying it or collects
outside of the brain in the spaces between the meninges causing
compression of the brain within the skull. little or no improvement
the first 4 to 8 weeks post onset & is followed by a period of rapid
recovery. The recovery then slows & stabilizes at a level higher.
Why would the watershed areas of blood supply to the brain be
less vulnerable during a stroke? In what medical situation would
the watershed areas of blood supply be more vulnerable to
oxygen deprivation to the brain cells they feed? Correct Answer
Watershed areas are areas in the brain where arteries overlap at
their boundaries, & where there is possibility of less damage
when there is obstruction of one of the arteries.
Hypoperfusion- when areas farthest away suffer because of
blockage to central areas inadequate blood supply.
