Cellular Adaptation Flashcards
Changes made by a cell in response to stress or stimuli
Cellular Adaptation
the adaptive response of our body
Physiologic
brought about or caused by a certain disease
Pathologic
5 types of adaptations
Hypertrophy
Hyperplasia
Atrophy
Metaplasia
Dysplasia
Increase in cell size
Hypertrophy
Increase in cell number
Hyperplasia
Decrease in cell size and number
Atrophy
Change in one cell type to another
Metaplasia
Abnormality of cell development
Dysplasia
Occurs in cells that are not capable of dividing
Hypertrophy
3 types of hypertrophy
True
False
Compensatory
True hypertrophy is stimulated by
hormone
False hypertrophy is due to
excessive accumulation of metabolites
hypertrophy that occurs in paired organs
compensatory
Adaptive response of the cells capable of replication
Hyperplasia
2 factors for hyperplasia
Hormonal
Compensatory
Atrophy is due to
decreased protein synthesis
Increased protein degredation
types of atrophy
physiologic
pathologic
types of pathologic atrophy
Atrophy of disuse
Vascular atrophy
Starvation atrophy
Loss of endocrine hormone stimulation
Pressure Atrophy
Decrease in size because that part is not used
Atrophy of disuse
Atrophy due to Ischemia/blood supply being cut off
Vascular atrophy
Muscle shrinkage due to stravation
Starvation atrophy
Decline in hormone level causing thin/small organs
Loss of endocrine hormone stimulation
Atrophy due to increase pressure
Pressure atrophy
