What is hyperplasia?

A decrease in size of cells due to reduced stimulation

A shrinkage of an organ or tissue from a decrease in cell size and number

An increase in cell size due to synthesis of more structural components

Loss of hormonal stimulation

Increased production of cellular proteins (correct)

Decreased functional demand

Synthesis of fewer structural components
