Pathology MCQs (part 3)!!!

69- If you see cellular swelling , plasma membrane blubbing, ion
of microvillus, mitochondrial swelling and cytoplasmic esinophlic,
so , you can tell that these cell are in:

b. Reversible cell injny
c. Apoptons.
d. necrosis

e. Apoptotic body.
77- Regarding the differences between apoptosis and necrosis ,
which is wrong:
a. Cells are enlarged in necrosis and shrinkage in apoptosis.
b. Plasma membrane in disrupted in necrosis and intact in
apoptosis.
c. The nucleolus shows pyknous, karyorshexis or karyolyris in
necrosis and fragmentation of nucleus in aptoptosis.
