Morphologic changes indicative of cell death are called?

• A. Ischemia
• B. Necrosis
• C. Chest physical therapy
• D. Seclusion

Answer: (B)

Necrosis represents the morphologic changes associated with irreversible cell death. When cells are damaged beyond repair, their membranes lose integrity, organelles swell, and the nucleus undergoes characteristic changes (pyknosis, karyorrhexis, followed by karyolysis). The cell’s contents leak into surrounding tissue, triggering an inflammatory response. Ischemia, while a common cause of cell injury that can lead to necrosis, is not the morphologic change itself. The other options are unrelated to cell death morphology—one is a treatment technique, the other a social/behavioral term.
