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.
Substance release at the synapse 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 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 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 ischemic but not infarcted (salvageable) tissue. Peri-infarct
tissue.
-no structural damage
Cerebral infarction 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 Toxins (usually amino acids) that overstimulate glutamate
release and cause neuron suicide.
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
Subarachnoid hemorrhage 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
Meningitis Bacterial- Meningococcus and S. pneumococcus bacteria are
most common
Viral- Specific pathogen cannot be found in CSF
Prostate cancer prevention -Eat a low fat diet
- Slow growing cancer so DRE and PSA testing prevents
