GNRS515 - Advanced
Pathophysiology - Exam #1 well
answered to pass
True - ANS ✔T/F: Non-dividing cells, such as myocardial fibers, are capable of hypertrophy, but
not hyperplasia.
False - ANS ✔T/F: Dysplasia is a common type of normal cellular adaptation.
False - ANS ✔T/F: Hypertrophy and hyperplasia rarely occur together.
True - ANS ✔T/F: A man with a history of smoking has a bronchial biopsy showing that the
normal columnar ciliated epithelial cells have been replaced by stratified squamous epithelial
cells. The man is correctly told that this process could be reversed if he quits smoking.
True - ANS ✔T/F: Dysplastic changes may be reversible, but more commonly become malignant.
B. Metaplasia - ANS ✔Which type of cell adaptation occurs when normal columnar ciliated
epithelial cells of the bronchial lining have been replaced by stratified squamous epithelial cells?
A. Hyperplasia
B. Metaplasia
C. Dysplasia
D. Anaplasia
,B. Hormonal Hyperplasia - ANS ✔The mammary glands enlarge during pregnancy primarily as a
consequence of:
A. Compensatory hyperplasia
B. Hormonal hyperplasia
C. Hormonal anaplasia
D. Hormonal dysplasia
B. They increase in size - ANS ✔When the heart's workload increases, what changes occur to
the myocardial cells?
A. They divide
B. They increase in size
C. They increase in number
D. They undergo metaplasia
A. Hyperplasia - ANS ✔After ovulation, the uterine endometrial cells divide under the influence
of estrogen; this is an example of hormonal:
A. Hyperplasia.
B. Dysplasia.
C. Hypertrophy
D. Anaplasia
D. Pathologic Hyperplasia - ANS ✔The abnormal proliferation of cells in response to excessive
hormonal stimulation is called:
, A. Dysplasia.
B. Pathologic dysplasia
C. Hyperplasia
D. Pathologic hyperplasia
C. Compensatory Hyperplasia - ANS ✔Removal of part of the liver leads to ______________ of
the remaining liver cells.
A. Dysplasia
B. Metaplasia
C. Compensatory hyperplasia
D. Compensatory dysplasia
C. Cells swell because of the influx of NaCl - ANS ✔During ischemia, what effect does the loss of
the adenosine triphosphate (ATP) level have on cells?
A. Cells shrink because of the influx of Ca
B. Cells shrink because of the influx of KCl
C. Cells swell because of the influx of NaCl
D. Cells swell because of the influx of NO
B. Influx of calcium ions halts ATP production - ANS ✔What is a consequence of plasma
membrane damage to the mitochondria?
A. Enzymatic digestion halts DNA synthesis.
B. Influx of calcium ions halts ATP production
C. Reduction in ATP production caused by edema from an influx in sodium
