Questions & Verified Answers
1. A patient is diagnosed with a condition where there is a decrease in the size of the cells in the leg
muscles due to prolonged immobilization. This is an example of:
A. Hypertrophy
B. Metaplasia
C. Hyperplasia
D. Atrophy
Answer: D
Rationale: Atrophy is a decrease or shrinkage in cellular size, often caused by disuse, denervation, or lack of endocrine
stimulation.
2. Which cellular adaptation is characterized by the replacement of one mature cell type by another, less
differentiated cell type?
A. Dysplasia
B. Neoplasia
C. Anaplasia
D. Metaplasia
Answer: D
Rationale: Metaplasia is the reversible replacement of one mature cell by another, such as the change in bronchial lining
due to smoking.
3. Dysplasia is best described as:
A. An increase in the number of cells
B. Abnormal changes in the size, shape, and organization of mature cells
C. Programmed cell death
D. A decrease in cell size
Answer: B
Rationale: Dysplasia refers to abnormal changes in size, shape, and organization; it is often called atypical hyperplasia and
can be a precursor to cancer.
4. Which type of necrosis is typically associated with hypoxic injury in the brain?
A. Coagulative necrosis
B. Liquefactive necrosis
C. Caseous necrosis
D. Fat necrosis
Answer: B
Rationale: Liquefactive necrosis occurs in the brain because brain cells are rich in digestive hydrolytic enzymes and lipids.
5. Free radicals cause cell damage by:
A. Stealing electrons from other molecules (oxidative stress)
B. Increasing ATP production
C. Repairing DNA sequences
D. Decreasing membrane permeability
Answer: A
Rationale: Free radicals are highly reactive atoms with unpaired electrons that damage lipids, proteins, and DNA through
oxidation.
