1. Which cellular adaptation is characterized by the replacement of one mature cell type by
another adult cell type, often in response to chronic irritation?
A. Hyperplasia
B. Dysplasia
C. Anaplasia
D. Metaplasia
Answer: D
Conceptual Explanation: Metaplasia is a reversible change where one adult cell type is
replaced by another to better withstand adverse environmental conditions.
2. Programmed cell death that does not elicit an inflammatory response is known as:
A. Apoptosis
B. Liquefactive necrosis
C. Coagulative necrosis
,D. Caseous necrosis
Answer: A
Conceptual Explanation: Apoptosis is a self-destructive process that eliminates unwanted
cells without causing inflammation or damage to surrounding tissues.
3. During the inflammatory response, which chemical mediator is primarily responsible for
increasing capillary permeability and immediate vasodilation?
A. Interferons
B. Prostaglandins
C. Leukotrienes
D. Histamine
Answer: D
Conceptual Explanation: Histamine is released from mast cells immediately following
injury, leading to rapid vasodilation and increased capillary permeability.
4. A wound that heals by secondary intention is characterized by:
A. Minimal tissue loss and rapid closure
B. High risk of infection and extensive scar tissue
C. Surgical suturing of clean edges
D. Regeneration of identical functional cells
, Answer: B
Conceptual Explanation: Secondary intention occurs when there is significant tissue loss;
the wound remains open and fills with granulation tissue, leading to more scarring and
infection risk.
5. Which type of hypersensitivity reaction is mediated by IgE antibodies binding to mast cells,
causing the release of histamine?
A. Type IV (Cell-mediated)
B. Type II (Cytotoxic)
C. Type III (Immune Complex)
D. Type I (Immediate)
Answer: D
Conceptual Explanation: Type I hypersensitivity involves IgE-mediated mast cell
degranulation, commonly seen in allergic rhinitis and anaphylaxis.
6. In the context of Systemic Lupus Erythematosus (SLE), what is the primary underlying
mechanism of tissue damage?
A. Direct viral invasion of connective tissue
B. Destruction of CD4 T-cells by retroviruses
C. Failure of the thyroid to produce T3 and T4
D. Deposition of circulating immune complexes in various organs
