increase in number of cells in an organ or tissue
in acquired benign changes, what is hypertrophy?
increase in size of cells
in acquired benign changes, what is atrophy?
decrease in cell size by loss of cell substance
what may cause atrophy?
decreased workload
loss of innervation
decreased blood supply
inadequate nutrition
decreased endocrine stimulation
in congenital/developmental change, what is hypoplasia? agenesis?
defective formation or incomplete development of a part

absence/failure of formation
in acquired premalignant change, what is metaplasia?

not the same cell
body uses metaplasia on stem cells to produce what it needs
cleans away what 'died' then creates new (i.e. squamous to columnar)
in acquired premalignant change, what is dysplasia? other terms?
abnormal tissue change which is less differentiated (most likely to be precancerous)

also use terms dedifferentiated or poorly differentiated
in acquired malignant change, what is anaplasia?
total loss of differentiation as might occasionally be seen in malignant neoplasms
