🧬 Section 1: Cellular Adaptation, Injury &
Neoplasia (Questions 1-25)
1. A patient with chronic hypertension has an
enlarged heart. This increase in muscle mass is
primarily due to which cellular adaptation?
• A) Hyperplasia
• B) Metaplasia
• C) Hypertrophy
• D) Dysplasia
• ☑VERIFIED ANSWER: C) Hypertrophy
• Rationale: Hypertrophy is an increase in
the size of cells, leading to an enlarged
, organ. Cardiac muscle cells are terminally
differentiated and cannot divide, so they
adapt to increased workload through
hypertrophy, not hyperplasia (increase in
cell number). This is the primary mechanism
by which the heart compensates for chronic
pressure overload in hypertension.
2. The irreversible point in cellular injury
where cell death is inevitable, even if the
stressor is removed, is known as the:
• A) Point of no return
• B) Cellular apoptosis threshold
• C) Necrotic point
• D) Ischemic threshold
• ☑VERIFIED ANSWER: A) Point of no return
• Rationale: The "point of no return" is a key
concept in cellular injury where
, mitochondrial damage becomes so severe
that ATP production ceases entirely, leading
to irreversible membrane and DNA damage.
Once this point is reached, cell death is
inevitable regardless of intervention.
3. Which of the following is a characteristic
feature of apoptosis?
• A) Elicits a significant inflammatory
response
• B) Results in cellular swelling and rupture
• C) Involves organized cell shrinkage and
fragmentation
• D) Is always a pathological process
• ☑VERIFIED ANSWER: C) Involves organized
cell shrinkage and fragmentation
• Rationale: Apoptosis is a programmed,
controlled cell death that does not cause
, inflammation. It involves organized cell
shrinkage, membrane blebbing, and
fragmentation into apoptotic bodies that
are phagocytosed without triggering an
inflammatory response. Necrosis is
characterized by cell swelling, rupture, and
inflammation.
4. Ischemia-reperfusion injury causes
additional cellular damage primarily due to:
• A) Immediate restoration of ATP levels
• B) Influx of calcium and generation of
oxygen-free radicals
• C) Decreased intracellular pH
• D) Inhibition of inflammatory cells
• ☑VERIFIED ANSWER: B) Influx of calcium
and generation of oxygen-free radicals
