Cellular Adaptation, Inflammation, and Immunity (Questions 1–25)
1. What is cellular hypertrophy?
a) Increase in cell number
b) Increase in cell size
c) Cell death
d) Decrease in cell size
b) Increase in cell size
Rationale: Hypertrophy is an adaptive response where cells increase in size to meet increased
functional demand, such as in cardiac muscle during hypertension.
2. What is the primary cause of apoptosis?
a) Uncontrolled cell division
b) Programmed cell death
c) Necrosis from injury
d) Cellular hypertrophy
b) Programmed cell death
,Rationale: Apoptosis is a controlled process of programmed cell death to eliminate damaged or
unnecessary cells, unlike necrosis, which is uncontrolled.
3. What is the role of cytokines in inflammation?
a) Inhibit immune response
b) Mediate and amplify inflammation
c) Cause cell death
d) Reduce blood flow
b) Mediate and amplify inflammation
Rationale: Cytokines are signaling molecules that recruit immune cells and amplify the
inflammatory response.
4. What is the hallmark of acute inflammation?
a) Fibrosis
b) Neutrophil infiltration
c) Chronic lymphocyte presence
d) Tissue regeneration
b) Neutrophil infiltration
Rationale: Acute inflammation is characterized by rapid neutrophil infiltration to combat
pathogens or injury.
5. What is the primary function of B lymphocytes?
a) Phagocytosis
b) Produce antibodies
c) Kill infected cells
d) Present antigens
b) Produce antibodies
Rationale: B lymphocytes produce antibodies to neutralize pathogens in humoral immunity.
6. What is an autoimmune disease?
a) Immune system attacks self-antigens
b) Immune system fails to respond
c) Bacterial infection
d) Viral infection
a) Immune system attacks self-antigens
Rationale: Autoimmune diseases occur when the immune system mistakenly targets the body’s
own tissues, as in rheumatoid arthritis.
7. What is the role of histamine in inflammation?
a) Inhibits blood flow
b) Increases vascular permeability
c) Reduces pain
d) Prevents immune response
b) Increases vascular permeability
Rationale: Histamine, released by mast cells, causes vasodilation and increased vascular
permeability, leading to swelling and immune cell recruitment.
, 8. What is metaplasia?
a) Increase in cell number
b) Replacement of one cell type with another
c) Cell death
d) Decrease in cell size
b) Replacement of one cell type with another
Rationale: Metaplasia is an adaptive change where one differentiated cell type is replaced by
another, often in response to chronic irritation.
9. What is the primary source of energy for cellular processes during
inflammation?
a) Glucose
b) Protein
c) Lipid
d) Nucleic acid
a) Glucose
Rationale: Glucose is the primary energy source for cells, especially during high-energy
demands like inflammation.
10. What is the role of T-helper cells?
a) Produce antibodies
b) Coordinate immune responses
c) Phagocytize pathogens
d) Store antigens
b) Coordinate immune responses
Rationale: T-helper cells activate and direct other immune cells, such as B cells and cytotoxic T
cells, via cytokine release.
11. What is the primary cause of anaphylaxis?
a) Bacterial infection
b) Severe allergic reaction
c) Autoimmune response
d) Viral infection
b) Severe allergic reaction
Rationale: Anaphylaxis is a life-threatening type I hypersensitivity reaction triggered by
allergens, causing widespread histamine release.
12. What is dysplasia?
a) Normal cell growth
b) Abnormal cell growth and differentiation
c) Increase in cell size
d) Cell death
b) Abnormal cell growth and differentiation
Rationale: Dysplasia involves abnormal changes in cell size, shape, and organization, often a
precursor to cancer.
