1. Which of the following best describes metaplasia?
A) Increase in cell size
B) Reversible replacement of one mature cell type by another
C) Increase in cell number
D) Programmed cell death
Answer: B
Rationale: Metaplasia is an adaptive change where one differentiated cell type is replaced by another,
often due to chronic irritation.
2. A biopsy of the cervix shows dysplastic cells. This finding indicates:
A) Normal tissue
B) Disordered growth with atypical cells
C) Malignant transformation
D) Inflammatory response
Answer: B
Rationale: Dysplasia is characterized by disordered growth and atypical cells, often a precursor to
malignancy.
3. Which type of necrosis is most commonly associated with ischemia in the heart?
A) Fat necrosis
B) Coagulative necrosis
C) Liquefactive necrosis
,D) Caseous necrosis
Answer: B
Rationale: Coagulative necrosis occurs in ischemic injury to solid organs like the heart, kidney, and
spleen.
4. Apoptosis differs from necrosis in that apoptosis:
A) Causes inflammation
B) Is an active, programmed process
C) Affects groups of cells
D) Is always pathological
Answer: B
Rationale: Apoptosis is a regulated, energy-dependent process that does not cause inflammation.
5. Which of the following is a major mechanism of cellular injury caused by free radicals?

B) Lipid peroxidation of membranes
C) Increased ATP production
D) Enhanced protein synthesis
Answer: B
Rationale: Free radicals cause lipid peroxidation, damaging cell membranes and leading to cell death.
