What is Apoptosis? - ANS-A programmed cell death
Aneuploid cells - ANS-Cells that do not contain a multiple of 23
chromosomes.
Aneuploid cell containing 3 copies of 1 chromosome - ANS-Trisomic
-condition called trisomy
Most well know example of aneuploidy in an autosome is: - ANS-
trisomy of the 21st chromosome
Trisomy of 21st Chromosome also known as - ANS-Down Syndrome
Characteristics of Downs syndrome - ANS-IQ 25-70
Facial features: low nasal bridge, protruding tongue, and flat low-set
ears
Penetrance - ANS-The percentage of individuals with a specific
genotype who also exhibit the expected phenotype.
,An example of Penetrance would be what disease? - ANS-
Huntington disease
Incomplete penetrance - ANS-Individuals who have disease causing
allele may not exhibit the disease phenotype at all, even though the
allele and the associated disease may be transmitted to the next
generation
Huntington disease is autosomal ____ - ANS-dominant
Huntington's features are - ANS-Progressive dementia and
increasingly uncontrolled movement of the limbs.
Key feature of Huntington's - ANS-S/s not usually seen until age 40
or later
Example of age dependent penetrance - ANS-Huntington disease
Expressivity - ANS-The extent of variation in phenotype associated
with a particular genotype.
Well-known example of variable expressivity in an autosomal
dominant disease is - ANS-Type 1 neurofibromatosis, or von
Recklinghausen disease
What is necrosis? - ANS-Death of most or all of the cells in an organ
or tissue due to disease, injury, or failure of the blood supply.

plasma membrane structure
2) Organelle swelling
3) Mitochondrial dysfunction
, Hypoxia - ANS-What is the #1 major cause of cellular injury leading
to necrosis. (especially the kidney and heart)
What is hypertrophy? - ANS-Is an increase in the size of cells
Physiologic hypertrophy - ANS-Hypertrophy of myocardial cells
such as in endurance training
Pathologic hypertrophy - ANS-Occurs secondary to HTN
What is Hyperplasia - ANS-Increase in the number of cells
Compensatory hyperplasia - ANS-Removal of 70% of the liver- can
regenerate in about 2 weeks
What is Metaplasia - ANS-Replacement of cells
Example of Metaplasia - ANS-Normal columnar ciliated epithelial
cells of the brohchial lining have been replaced by stratified
squamous epithelial cells
During ischemia, what effect does the loss of the ATP levels have on
cells? - ANS-Reduction in ATP levels causes the plasma
membrane's sodium-potassium pump and sodium-calcium
exchange to fail, which leads to an intracellular accumulation of
sodium and calcium and diffusion of potassium out of the cell.
Sodium and water then can enter the cell freely, and cellular
swelling results.
Free radicals play a major role in the initiation and progression of
which diseases? - ANS-These reactive oxygen species play major
