What is the mechanism of necrosis?
Enzymatic or ischemic process
Genetically programmed cell death
Active process
Both physiologic and pathologic
Which process is considered a passive process?
Apoptosis
Necrosis
Both apoptosis and necrosis
Neither apoptosis nor necrosis
What is the physiologic or pathologic role of apoptosis?
Invariably pathologic
Both physiologic and pathologic
Only physiologic
Only pathologic
How does cell size change in necrosis?
Enlarged (swelling)
Reduced (shrinkage)
No change
Varies depending on the cell type
Which type of cell death affects a group of cells?
Apoptosis
Necrosis
Both apoptosis and necrosis
Neither apoptosis nor necrosis
What happens to the nucleus during apoptosis?
Pyknosis, karyorrhexis, karyolysis
Fragmentation into nucleosome-size fragments
No change
Complete dissolution
What is the state of the plasma membrane in necrosis?
Intact; altered structure
Disrupted
Intact; may be released in apoptotic bodies
No change
Which process involves enzymatic digestion and leakage of cellular contents?
Apoptosis
Necrosis
Both apoptosis and necrosis
Neither apoptosis nor necrosis
Is inflammation present in necrosis?
Yes
No
Sometimes
Depends on the tissue type
What marker is associated with apoptosis?
No marker
Annexin V
Caspase 3
Bcl-2
What pattern is observed in DNA electrophoresis for necrosis?
Smear pattern
Step-ladder pattern
No pattern
Random fragmentation
Which process is genetically programmed?
Apoptosis
Necrosis
Both apoptosis and necrosis
Neither apoptosis nor necrosis
What is the state of cellular contents in apoptosis?
Intact; may be released in apoptotic bodies
Enzymatic digestion; may leak out of cell
Completely dissolved
No change
Which process is invariably pathologic?
Necrosis
Apoptosis
Both apoptosis and necrosis
Neither apoptosis nor necrosis
What is the cell size change in apoptosis?
Reduced (shrinkage)
Enlarged (swelling)
No change
Varies depending on the cell type
