An increase in the number of new cells in an organ or tissue that is reversible when the stimulus for production of new cells is removed is termed a) Hyperplasia. Hyperplasia occurs as cells multiply and are subjected to increased stimulation resulting in tissue mass enlargement. b) Hypertrophy. Hypertrophy is an increase in size and bulk of tissue that does not result from an increased number of cells. c) Atrophy. Atrophy refers to reduction in size of a structure after having come to full maturity. d) Neoplasia. With neoplasia, the increase in the number of new cells in an organ or tissue continues after the stimulus is removed.
