types of adaptation

physiologic pathologic compensatory Signup and view all the answers

it occurs due to a normal stressor; results in enhanced function

physiologic Signup and view all the answers

an adaptation to positively counteract reduction in function

compensatory Signup and view all the answers

it occurs due to an abnormal stressor; results in dysfunction and mortality

pathologic Signup and view all the answers

increase in the size of cells which results in enlargement of the organs (no new, just bigger)

hypertrophy Signup and view all the answers

increased number of cells in an organ or tissue

hyperplasia Signup and view all the answers

a reversible change in which one ADULT cell type is replaced by another ADULT cell

metaplasia Signup and view all the answers

shrinkage in the size of the cell by loss of substance (they are not dead just diminished function)

premalignant change

dysplasia Signup and view all the answers

cells are undifferentiated with variable nuclear and cell structures and numerous mitotic figures

dysplasia Signup and view all the answers

“new growth”

neoplasia Signup and view all the answers

considered less serious because they do not spread and are not life threatening (except in the brain)

aplasia Signup and view all the answers

aplasia results during fetal development

agenesis (absence of an organ) Signup and view all the answers

decrease in cell production; incomplete development of an organ so that it fails to reach adult size
