Death of tissue is known as what?

• A. Necrosis
• B. Atrophy
• C. Hyperplasia
• D. Ulcer

Answer: (A)

Death of tissue is necrosis. Necrosis refers to the death of cells or tissue due to injury, lack of blood supply, infection, or toxins, leaving a patch of tissue that can no longer function. It’s different from atrophy, which is a decrease in tissue size; from hyperplasia, which is an increase in the number of cells; and from an ulcer, which is a surface sore that exposes tissue but is defined by the lesion rather than the dead tissue itself. Necrosis can take different forms depending on the tissue and cause, such as coagulative or liquefactive, and it often triggers inflammation as the body responds to the dead tissue.
