NR 507 FINAL EXAM WITH
CORRECT ANSWERS 2025
GRADED A+
Dermatomes correct answers >> area of the skin
that is mainly supplied by branches of a single spinal
sensory nerve root. These spinal sensory nerves enter the
nerve root at the spinal cord, and their branches reach to
the periphery of the body.
Substance release at the synapse correct answers >>
Acetylcholine- Excitatory or inhibitory- alzheimers
Norepi- Excitatory or inhibitory- sleep/wake cycle, SYNS
transmission
Dopa- Excitatory (h1 and h2 receptors) and inhibitory (H3
receptors). parkinson disease
Spondylolysis correct answers >> structural defect
(degeneration, fracture, or developmental defect) in the
GRADED A+
,pars interarticularis of the vertebral arch (the joining of
the vertebral body to the posterior structures). The
lumbar spine at L5 is affected most often.
-Heredity
-Other congenital spinal defects
motor and sensory areas of the brain correct answers
>> Parietal lobe- major area for somatic sensory input,
located along the postcentral gyrus. which is adjacent to
the primary motor area in the precentral gyrus.
Primary motor area (Brodmann area 4)- located along the
precentral gyrus forming the primary voluntary motor
area (homunculus) (little man).
Association fibers provide communication between
sensory and motor
Ischemic penumbra correct answers >> ischemic but
not infarcted (salvageable) tissue. Peri-infarct tissue.
-no structural damage
Cerebral infarction correct answers >> ischemic-
white infarct (affected area is pale and soft 6-12 hours
after). necrosis appears by 48 to 72 hours.
GRADED A+
, Infiltration of macrophages and phagocytosis of necrotic
tissue. necrosis resolves around the 2nd week. glial
scarring.
excitotoxins correct answers >> Toxins (usually
amino acids) that overstimulate glutamate release and
cause neuron suicide.
Agnosia correct answers >> the inability to
recognize familiar objects.
-tactile/spatial-parietal lobe
-Gerstmann syndrome (loss of spatial orientation of
fingers, body, sides and #s)- L angular gyrus (Parieral)
-Object- Temporo-occipital area
-Associated with CVAs
Subarachnoid hemorrhage correct answers >>
Bleeding into the subarachnoid space, where the
cerebrospinal fluid circulates.
-ruptured intracranial aneurysm/trauma
-IICP/irritates meningeal tissues/produces inflammation,
blood coats nerve roots, impairs CSF circulation
-compensatory increase in SBP
