Cellular Swelling Fatty Change Normal Cell stress adaptation Fail to adapt atrophy. hypertrophy. Hyperplasia. dysplasia. metaplasia. injuries Reversible Cellular Swelling Fatty Change Irreversible Necrosis Apoptosis

cellular adaptation Cellular adaptation is a state that lies intermediate between the normal (unstressed )cell and the injured (over stressed cells). The adaptation may be physiological (normal) or pathological (abnormal). Five major types of adaptation include atrophy. hypertrophy. Hyperplasia. dysplasia. metaplasia.
