Flashcards in cellular adaptation Deck (11):
1

cellular responses to persistent sublethal injury, physical or chemical. Reversible

Cellular adaptation:

2

Increase in size of tissue due to increased number of component cells.

hyperplasia

3

Proliferation of prostatic glands and stroma resulting in enlargement of the gland with obstruction of urine flow through the bladder outlet.

NODULAR HYPERPLASIA, PROSTATE GLAND

4

Pathogenesis of NODULAR HYPERPLASIA, PROSTATE GLAND

unknown; altered normal ratio of testosterone to estrogen that develops in the elderly.

5

Usually secondary to chronic stimulation by corticotropin due to
Bilateral diffuse or nodular hyperplasia of adrenal glands

ADRENAL CORTICAL HYPERPLASIA

6

Proliferative lesions of the endometrium usually resulting from hyperestrinism
constitutes of morphologic & biologic continuum

ENDOMETRIAL HYPERPLASIA

7

increased size of an organ due to increased size of component cells

hypertrophy

8

Pure hypertrophy without hyperplasia occurs where

only in heart and skeletal muscle

9

Diminution in size or function of organ due to decrease in size of cells.

atrophy

10

Conversion of one differentiated (mature) cell type into another

metaplasia

11

Abnormal growth and differentiation
Variations in size and shape of cells
Enlargement, irregularity, and hyperchromasia of nuclei
Disorderly arrangement of cells within the epithelium
A preneoplastic lesion (a stage in the cellular evolution to cancer)

dysplasia
