Cell Adaptation Flashcards
ability of
cells to respond
to various types
of stimuli and
adverse
environmental
changes
Cell Adaptation
results in decreased size or wasting
of the concerned tissue, organ or
part of the body
Atrophy
Causes of Atrophy (5)
Poor nourishment
Decreased blood supply
Lack of workload or exercise
Loss of control by nerves or hormones
Intrinsic disease of the tissue or organ
is the increase in the size of a cell.
Hypertrophy
is the increase in size due to increased workload or exercise.
Physiological Hypertrophy
Increase in cell size in
response to pathological
changes is called
pathological hypertrophy.
Increase in size of the cells of an
organ that occurs in order to
compensate the loss or dysfunction
of another organ of same type
Compensatory Hypertrophy
defined as abnormal or unusual proliferation (multiplication) of cells due to
constant cell division.
Hyperplasia
results in gross enlargement of the organ.
Hyperplasia
is the momentary adaptive response to routine
physiological changes in the body
Physiological hyperplasia
is the increase in number of cells due to abnormal
increase in hormone secretion.
Pathological Hyperplasia
is the increase in number of cells in order to replace
the damaged cells of an organ or the cells removed from the organ.
Compensatory Hyperplasia
condition that involves replacement of one type of cell with another type of cell
Metaplasia
Replacement of cells in normal conditions is called physiological
hyperplasia
Physiological Metaplasia
irreversible replacement of cells due to constant exposure to
harmful stimuli.
