EVALUATED A+ |BRAND NEW!!
Dermatomes - CORRECT ANSWER--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 ANSWER--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 ANSWER--structural defect (degeneration,
fracture, or developmental defect) in the 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 ANSWER--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 ANSWER--ischemic but not infarcted
(salvageable) tissue. Peri-infarct tissue.
-no structural damage
, Cerebral infarction - CORRECT ANSWER--ischemic- white infarct
(affected area is pale and soft 6-12 hours after). necrosis appears by 48
to 72 hours.
Infiltration of macrophages and phagocytosis of necrotic tissue.
necrosis resolves around the 2nd week. glial scarring.
excitotoxins - CORRECT ANSWER--Toxins (usually amino acids) that
overstimulate glutamate release and cause neuron suicide.
Agnosia - CORRECT ANSWER--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 ANSWER--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
