d. all of the above.
Accumulation of which of a. Calcium
the following molecules
results in irreversible cell Rationale: The accumulation of calcium causes
injury? irreversible mitochondrial injury.
a. Calcium
b. Melanin
c. Lipids
d. Water
,Adaptive cellular d.protect cells from injury.
mechanisms function to:
a. speed up cellular death.
b. prevent cellular aging.
c. treat disease.
d. protect cells from injury.
An individual with damage a. Skeletal muscles
to the spinal cord may Rationale: Lack of nerve stimulation to skeletal
experience atrophy of muscles results in muscle atrophy.
which of the following
organs?
a. Skeletal muscles

papillomavirus results in common cause of cervical dysplasia.)
cervical:
a. hormonal hyperplasia.
b. atrophy.
c. dysplasia.
d. metaplasia.
Ethanol (alcohol) causes c. Lipid accumulation in hepatocytes
cell injury by which of the
following mechanisms? Rationale: Ethanol metabolism causes lipid
accumulation in hepatocytes that decreases liver

hyperplasia, growth
factors stimulate cell Rationale: In response to tissue loss, surrounding cells
division in response to: are stimulated to replace the lost tissue.
a. decreased hormonal
stimulation.
b. ischemia.
