MSN 570 PATHO MIDTERM EXAM (Actual 2024-
2025) QUESTIONS AND ANSWERS
silent mutation - <<<Answers>>>A mutation that changes a
single nucleotide, but does not change the amino acid created.
Blood Brian Barrier - <<<Answers>>>The barrier system that
restricts the passage of various chemicals and microscopic
entities between the bloodstream and the central nervous
system. It still allows for the passage of essential substances
such as oxygen.
glial support cells - <<<Answers>>>similar to astroglia of the
brain rather than Schwann cells of the peripheral nervous
system
missense mutation - <<<Answers>>>A base-pair substitution
that results in a codon that codes for a different amino acid.
DNA and amino acids - <<<Answers>>>a type of evidence
for evolution; the more DNA and amino acids in common, the
more closely related
physiologic atrophy - <<<Answers>>>occurs with early
development
systemic lupus erythematosus - <<<Answers>>>chronic
autoimmune inflammatory disease of collagen in skin, joints,

sheath. Plaques occur in the brain and spinal cord causing
tremor, weakness, incoordination, paresthesia, and
disturbances in vision and speech
Loss of ATP in cells - <<<Answers>>>Cell death
increased intracranial pressure - <<<Answers>>>a raised
level of pressure within the skull above the normal and
healthy level
cerebral vasodilation - <<<Answers>>>Relaxation of cerebral
blood vessels that can lead to pooling of blood and inadequate
circulation.
pyruvic acid - <<<Answers>>>the three-carbon compound
that is produced during glycolysis and needed for both the
aerobic and anaerobic pathways of cellular respiration that
follow glycolysis
Asthma - <<<Answers>>>A chronic allergic disorder
characterized by episodes of severe breathing difficulty,
coughing, and wheezing. Obstructive
