Cell Adaptation Flashcards
what is hypertrophy?
increased size of cells
where is hypertrophy most common?
heart
skeletal muscle
organ/tissues
what is hyperplasia?
increased number of cells
why does hyperplasia occur?
hormonal
compensatory
is pathologic hyperplasia fulfilling a functional need?
no
what is metaplasia?
replacement of a cell type by another of the same germline
change from one differentiated cell to another cell type
what would squamous cell in the wrong place in the respiratory tract indicate?
squamous metaplasia
what is dysplasia?
abnormal pattern of tissue growth, disorderly arrangement of cells within epithelium
is dysplasia often associated with hyperplasia and/or metaplasia?
yes
what is atrophy?
decreased size of cells
what is hypoplasia?
when an organ fails to achieve its full size
is hypoplasia congenital?
yes
true/false: atrophy can be both a cause and/or a result of a disease process (pathologic)
true
is increased functional demand associated with hypertrophy?
yes
what is pathologic hypertrophy?
limit to which hypertrophy can compensate
