SECTION 1: CELLULAR FUNCTION & GENETICS Q1 – Q10
══════════════════════════════════════
Question 1 of 50
A 62-year-old man with poorly controlled hypertension presents for a routine
follow-up. On echocardiogram, his left ventricular wall thickness is increased
but chamber size is normal. His cardiologist explains this represents a cellular
adaptation to chronic pressure overload.
A. Hyperplasia
,2
B. Hypertrophy ✓ CORRECT
C. Metaplasia
D. Dysplasia
Correct Answer: B
Rationale: Hypertrophy is an increase in cell size in response to increased
workload, which is exactly what happens in the myocardium under chronic
pressure overload from hypertension. Hyperplasia involves an increase in cell
number, which does not occur in cardiac muscle because cardiomyocytes are
terminally differentiated. Metaplasia is a change from one mature cell type to
another, and dysplasia is disordered growth that is pre-neoplastic.
Question 2 of 50
A 58-year-old woman with chronic gastroesophageal reflux undergoes upper
endoscopy. The gastroenterologist notes that the normal squamous epithelium
of the distal esophagus has been replaced by salmon-colored columnar
mucosa. Biopsy confirms intestinal metaplasia.
A. Hyperplasia
B. Hypertrophy
C. Metaplasia ✓ CORRECT
D. Anaplasia
Correct Answer: C
Rationale: Metaplasia is the reversible replacement of one differentiated cell
type by another, as seen in Barrett's esophagus where chronic acid exposure
transforms squamous epithelium into columnar epithelium. This is a protective
adaptation, though it increases cancer risk. Anaplasia refers to loss of
,3
differentiation in malignant cells, and hyperplasia or hypertrophy describe
increased cell number or size, not a change in cell type.
Question 3 of 50
A pathologist examining a cervical Pap smear sees cells with enlarged,
hyperchromatic nuclei, loss of normal polarity, and failure of maturation from
basal to superficial layers. The changes are confined to the lower third of the
epithelium.
A. Atrophy
B. Hyperplasia
C. Metaplasia
D. Dysplasia ✓ CORRECT
Correct Answer: D
Rationale: Dysplasia is disordered epithelial growth characterized by nuclear
pleomorphism, hyperchromatism, and loss of normal maturation and polarity;
it is considered a pre-neoplastic change. Atrophy is a decrease in cell size,
hyperplasia is an increase in cell number, and metaplasia is a change in cell
type, none of which describe the disordered growth seen here.
Question 4 of 50
A 45-year-old man with severe alcohol use disorder and malnutrition is found
unconscious. His liver enzymes are elevated, and liver biopsy shows
hepatocyte swelling with clear cytoplasmic vacuoles displacing the nucleus to
the periphery.
, 4
A. Fatty change (steatosis) ✓ CORRECT
B. Hyaline change
C. Amyloid deposition
D. Hemosiderosis
Correct Answer: A
Rationale: Fatty change, or steatosis, is characterized by the accumulation of
triglycerides within hepatocytes, appearing as clear vacuoles that push the
nucleus to the periphery, giving a "signet ring" appearance. This is common in
alcohol-induced liver injury and metabolic syndrome. Hyaline change refers to
glassy eosinophilic material, amyloid deposition is extracellular, and
hemosiderosis involves iron accumulation.
Question 5 of 50
A 28-year-old woman presents with progressive muscle weakness and easy
fatigability. Electromyography shows decremental response, and she is
diagnosed with myasthenia gravis. The underlying pathophysiology involves
autoantibodies against which cellular target?
A. Acetylcholine receptors on the postsynaptic membrane ✓ CORRECT
B. Voltage-gated calcium channels on the presynaptic membrane
C. Dopamine receptors in the basal ganglia
D. Myelin basic protein in peripheral nerves
Correct Answer: A
Rationale: Myasthenia gravis is an autoimmune disorder where IgG antibodies
target acetylcholine receptors on the postsynaptic membrane of the
neuromuscular junction, leading to impaired neuromuscular transmission and
