What is the role of me-size fragments in the body?
What is the role of me-size fragments in the body?
- They play a pathologic role in cell injury (correct)
- They are a normal part of cell growth
- They play a physiologic role in eliminating unwanted cells
- They have no role in the body
What happens to cellular contents in me-size fragments?
What happens to cellular contents in me-size fragments?
- They are released into the bloodstream

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)
