Cellular Adaptation 1.Atrophy: decrease in cell size
2.Hypertrophy: increase in cell size
3.Hyperplasia: increase in cell number
4. Metaplasia: reversible replacement of one mature
cell type by another less mature cell type
5.Dysplasia (atypical hyperplasia): deranged cellular
growth (size, shape, and organization)
Metaplasia Reversible replacement of one cell by another cell
type
Bronchial metaplasia: (in smokers)
- normal columnar ciliated epithelial cells, are
replaced by stratified squamous epithelial cells (no
mucus secretion, no cilia)
- Can be reversed
- Can be transformed into cancer
Barrett esophagus:
- normal squamous epithelial lining of the
esophagus, is replaced by columnar epithelium
(goblet cells of the intestines)
- occurs as an adaptation to the chronic irritation of
GERD
- predisposes to esophageal adenocarcinoma
,Non-dividing cells, such as myocardial A.True
fibers, are capable of hypertrophy,
but not hyperplasia

cellular adaptation
A.True
B.False
Hypertrophy and hyperplasia rarely B.False
occur together.
A.True
B.False
A man with a history of smoking has a A.True
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cells have been replaced by stratified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
A.True
B.False
Dysplastic changes may be reversible, A.True
but more commonly become
malignant.
A.True
B.False
