Pathophys Ch 2

Front

What is cellular adaptation?

Back

Allows the stressed tissue to survive or maintain function.

Front

What are the types of cellular adaptations?

Back

Changes in cell size or number (Atrophy, Hypertrophy, Hyperplasia) and changes in cell type (Metaplasia, Dysplasia).

Front

What is atrophy?

Back

Degeneration of tissue/organs which often reduces size.

Front

What is hypertrophy?

Back

Overgrowth in size of cells/tissues/organs.

Front

What is hyperplasia?

Back

Increase in cell number.

Front

What is metaplasia?

Back

When one adult cell type is replaced with another type.

Front

What is dysplasia?

Back

Deranged cell growth that results in cells with varied sizes, shapes, and appearance.

Front

What are intracellular accumulations?

Back

Stressed cells may fill up with unused foods (lipids, glycogen), abnormal proteins, pigments (lipofuscin), and calcium salts.

Front

What is dystrophic calcification?

Back

Seen in injured tissue such as lesions in atherosclerosis of blood vessels.

Front

What is metastatic calcification?

Back

Occurs in normal tissues due to increased serum calcium levels beyond normal values.
