DPT 540 BLOOD BRAIN BARRIER EXAM QUESTIONS AND
ANSWERS WITH COMPLETE SOLUTIONS VERIFIED LATEST
UPDATE
Anoxia
Complete lack of oxygen
Hypoxia
An organ experiences oxygen delivery that is insufficient to meet the metabolic needs of
the tissue.
Hypglycemia
a condition in which your blood sugar (glucose) level is lower than the standard range
Hyperglycemia
high blood glucose (blood sugar)
Cerebrospinal Fluid (CSF)
plasma-like clear fluid circulating in and around the brain and spinal cord
-produced by the choroid plexus inside the ventricles
SCALP
Skin
Connective tissue
Aponeuroses
Loose areolar connective tissue
Pericranium
Subarachnoid Space
, Cerebrospinal fluid-filled space
-Major arteries of the brain travel within this space.
Average weight of brain
-1400 grams
-2% of total b weight
-15-20% of total body metabolism (resting)
Brain metabolism Neurons
major metabolic need is for transport of ions across the neuronal membrane
Aerobic metabolism.
glucose is the principle energy source
Brain metabolism - Minimal
Neuronal glycogen stores and brain oxygen stores
Cerebral blood flow
Directly related to metabolic activity
Cerebral blood flow output
approx 750-800 ml/min in adults
15-20% of total cardiac output
Diminished cerebral blood flow
Seconds - interrupted oxygen supply (Anoxia), electrical activity of neurons ceases
-Minutes irreversible damage to neurons
Interruption of blood supply causes unconsciousness in 5-10 seconds
