Which term means tissue death?

Which term means tissue death?

• A. Necrosis
• B. Atrophy
• C. Apoptosis
• D. Gangrene

Answer: (A)

Necrosis is tissue death caused by irreversible injury, such as severe ischemia or toxin exposure. It involves loss of cell membrane integrity, uncontrollable cell swelling, and the release of cellular contents, which triggers inflammation in the surrounding tissue. This sets it apart from apoptosis, which is a controlled, non-inflammatory cell suicide, and from atrophy, which is a decrease in cell size or number. Gangrene refers to a clinically evident condition where necrotic tissue becomes infected or decayed, often with characteristic characteristics like foul odor or gas formation in certain types. So the term that means tissue death is necrosis.
