Cell Adaptation

study of disease

study of cause of disease

progression of disease

the capability of a cell to adjust their structure and function in response to any various conditions

adaptation results in?

clinical manifestations

a cell that is continuously dividing

a cell that is non-dividing

three cell proliferation

a cell that is quiscent

types of cellular adaptations

types of adaptation

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

an adaptation to positively counteract reduction in function

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

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

increased number of cells in an organ or tissue

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

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

fertile fields

three metaplasia

premalignant change

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

atypical proliferative changes due to chronic irritation or inflammation

“new growth”

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

a cancer neoplasia

failure of cell production

aplasia results during fetal development

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

these are reversible changes
