1. Dermatomes 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.
2. Substance re- Acetylcholine- Excitatory or inhibitory- alzheimers
lease at the
synapse Norepi- Excitatory or inhibitory- sleep/wake cycle, SYNS transmission
Dopa- Excitatory (h1 and h2 receptors) and inhibitory (H3 receptors). parkinson
disease
3. Spondylolysis 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
4. motor and senso- Parietal lobe- major area for somatic sensory input, located along the postcentral
ry areas of the gyrus. which is adjacent to the primary motor area in the precentral gyrus.
brain
Primary motor area (Brodmann area 4)- located along the precentral gyrus form-
ing the primary voluntary motor area (homunculus) (little man).
Association fibers provide communication between sensory and motor
5. Ischemic penum- ischemic but not infarcted (salvageable) tissue. Peri-infarct tissue.
bra -no structural damage

6. Cerebral infarc- ischemic- white infarct (affected area is pale and soft 6-12 hours after). necrosis
tion appears by 48 to 72 hours.
Infiltration of macrophages and phagocytosis of necrotic tissue. necrosis resolves
around the 2nd week. glial scarring.
7. excitotoxins Toxins (usually amino acids) that overstimulate glutamate release and cause neu-
ron suicide.
8. Agnosia 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
9. Subarachnoid he- Bleeding into the subarachnoid space, where the cerebrospinal fluid circulates.
morrhage -ruptured intracranial aneurysm/trauma
-IICP/irritates meningeal tissues/produces inflammation, blood coats nerve roots,
impairs CSF circulation
-compensatory increase in SBP
10. Meningitis Bacterial- Meningococcus and S. pneumococcus bacteria are most common
Viral- Specific pathogen cannot be found in CSF
11. Prostate cancer -Eat a low fat diet
prevention - Slow growing cancer so DRE and PSA testing prevents
12. BPH and the uri- - Chronic inflammation
nary system -Bladder outflow obstruction
-Urge to pee often
-delay in starting stream
