300 Frequently Tested Questions & Verified CORRECT ANSWER with Detailed
Explanations | A+ Graded Study Guide
1. A cell exposed to chronic low oxygen levels undergoes a reversible size
reduction. This adaptation is called:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Atrophy
E. Hypertrophy
CORRECT ANSWER: D. Atrophy RATIONALE: Atrophy is the reduction in cell size
due to decreased workload, loss of innervation, diminished blood supply, or chronic
hypoxia. It is a reversible adaptive response.
2. A patient's bronchial epithelium changes from columnar to squamous cells due
to chronic cigarette smoking. This is an example of:
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Necrosis
E. Atrophy
CORRECT ANSWER: B. Metaplasia RATIONALE: Metaplasia is the replacement of
one mature cell type with another. Chronic smoking causes columnar epithelium to
convert to squamous epithelium, which is more resistant to irritation but loses normal
function.
,3. Which type of cell death is characterized by cell swelling, membrane rupture,
and an inflammatory response?
A. Apoptosis
B. Autophagy
C. Necrosis
D. Anoikis
E. Pyroptosis
CORRECT ANSWER: C. Necrosis RATIONALE: Necrosis is uncontrolled,
pathological cell death involving cell swelling, membrane disruption, and release of
cellular contents that trigger inflammation. It differs from apoptosis, which is
programmed and orderly.
4. Which organelle is primarily responsible for initiating the intrinsic pathway of
apoptosis?
A. Nucleus
B. Endoplasmic reticulum
C. Mitochondria
D. Lysosome
E. Golgi apparatus
CORRECT ANSWER: C. Mitochondria RATIONALE: The mitochondria release
cytochrome c in response to cellular stress, activating caspases and triggering the
intrinsic apoptosis pathway. This is a key mechanism of programmed cell death.
5. A cell increases in size due to increased workload. This is best described as:
A. Hyperplasia
B. Metaplasia
C. Atrophy
D. Dysplasia
,E. Hypertrophy
CORRECT ANSWER: E. Hypertrophy RATIONALE: Hypertrophy is an increase in
cell size without an increase in cell number, typically in response to increased workload.
Classic examples include cardiac muscle hypertrophy in hypertension and skeletal
muscle hypertrophy with exercise.
6. Which of the following best describes coagulative necrosis?
A. Liquefaction of tissue with pus formation
B. Preservation of tissue architecture with loss of nuclei
C. Cheese-like appearance of dead tissue
D. Fat cell destruction releasing fatty acids
E. Gangrenous destruction with bacterial invasion
CORRECT ANSWER: B. Preservation of tissue architecture with loss of nuclei
RATIONALE: Coagulative necrosis, most commonly seen in ischemic infarcts of solid
organs like the kidney and heart, preserves the tissue's structural outline while cellular
details are lost. It results from protein denaturation.
7. Free radical injury damages cells primarily by:
A. Increasing intracellular calcium
B. Lipid peroxidation of cell membranes
C. Inhibiting mitochondrial ATP production
D. Blocking protein synthesis
E. Activating anti-apoptotic genes
CORRECT ANSWER: B. Lipid peroxidation of cell membranes RATIONALE: Free
radicals attack polyunsaturated fatty acids in cell membranes via lipid peroxidation,
disrupting membrane integrity. They also damage DNA and proteins, leading to
widespread cellular injury.
8. Liquefactive necrosis is most commonly seen in:
, A. Myocardial infarction
B. Renal infarction
C. Brain infarction
D. Pulmonary tuberculosis
E. Fat tissue injury
CORRECT ANSWER: C. Brain infarction RATIONALE: Liquefactive necrosis occurs
when enzymatic digestion of dead cells results in a liquid viscous mass. The brain is
particularly susceptible due to its high lipid content and abundance of hydrolytic
enzymes.
9. Which adaptation involves an increase in the number of cells in a tissue?
A. Hyperplasia
B. Hypertrophy
C. Metaplasia
D. Atrophy
E. Dysplasia
CORRECT ANSWER: A. Hyperplasia RATIONALE: Hyperplasia is an increase in
cell number in a tissue or organ. It occurs in response to hormonal stimulation or
chronic irritation, such as endometrial hyperplasia due to estrogen excess.
10. Caseous necrosis is classically associated with which disease?
A. Stroke
B. Myocardial infarction
C. Tuberculosis
D. Pancreatitis
E. Gangrene
CORRECT ANSWER: C. Tuberculosis RATIONALE: Caseous necrosis has a soft,
cheese-like gross appearance and is characteristic of tuberculosis. It represents a
