Study Notes
Cell Death
Necrosis
- Enlarged cell size (swelling)
- Pyknosis, karyorrhexis, and karyolysis of the nucleus
- Disrupted plasma membrane
- Cellular contents may leak out of the cell due to enzymatic digestion
- Often accompanied by adjacent inflammation
- Always a pathologic process (result of irreversible cell injury)
Apoptosis
- Reduced cell size (shrinkage)
- Fragmentation of the nucleus into nucleosome-sized fragments
- Intact plasma membrane with altered structure and lipid orientation
- Cellular contents remain intact and may be released in apoptotic bodies
- No adjacent inflammation
- Can be a physiologic process (elimination of unwanted cells) or pathologic (after certain types of cell injury, such as DNA damage)
