MODULE 1 EXAM
1. True/False:
Hypertrophy can occur under normal and pathological conditions.
Correct Answer: True
Verified Explanation: Hypertrophy refers to the increase in size of cells and
consequently the a(ected organ. It can be physiologic, such as muscle
growth from exercise, or pathologic, as in cardiac hypertrophy from
hypertension.
,2. Match the definitions:
a. Sensitivity: Proportion of people _with_ a disease who test positive for the
disease.
b. Reliability: Likelihood of obtaining the same result with repeat testing.
c. Validity: The degree to which a tool measures what it is intended to
measure.
d. Specificity: Proportion of people _without_ a disease who test negative.
Verified Explanation: Sensitivity and specificity reflect a test's accuracy;
validity denotes its appropriateness, while reliability refers to its consistency
regardless of the operator.

3. Which are true of the mitochondria? (Select all that apply):
Correct Answer:
- They are involved in cellular respiration.
- They play a role in apoptosis.
Verified Explanation: Mitochondria are the site of aerobic respiration and ATP
production and are critical mediators of apoptosis via the cytochrome c
pathway.
, 4. True/False:
Persistent metaplasia can lead to dysplasia.
Correct Answer: True
Verified Explanation: Metaplasia is a reversible change in which one cell type
replaces another. If the injurious stimulus persists, metaplastic tissue may
undergo additional genetic and morphologic changes, evolving into dysplasia,
which is a preneoplastic lesion (a precursor to cancer).

5. True/False:
Barrett esophagus is an example of dysplasia.
Correct Answer: False
Verified Explanation: Barrett esophagus is characterized by the replacement
of the normal squamous epithelium of the esophagus with columnar
epithelium, a classic example of metaplasia, not dysplasia.
---
6. True/False:
Persistent dysplasia eventually results in cancer.
Correct Answer: True
