Encyclopedia Article for necrotic

necrosis

death of a circumscribed area of plant or animal tissue as a result of an outside agent; natural death of tissue is called necrobiosis. Necrosis may follow a wide variety of injuries, both physical (cuts, burns, bruises) and biological (effects of disease-causing agents). The sign of necrosis-dead tissue-is called a lesion; it is often of diagnostic value. Necrosis is brought about by intracellular enzymes that are activated upon injury and proceed to destroy damaged cells
