T/F: Non-dividing cells, such as myocardial fibers, are capable of hypertrophy, but not
hyperplasia.
True
T/F: Dysplasia is a common type of normal cellular adaptation.
False
T/F: Hypertrophy and hyperplasia rarely occur together.
False
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ciliated epithelial cells have been replaced by stratified squamous epithelial cells.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
T/F: Dysplastic changes may be reversible, but more commonly become malignant.
True
