What are the nuclear changes that occur during necrosis? (Select all that apply) A) Nuclear swelling and expansion B) Karyorrhexis: nuclear fragmentation C) Pyknosis: small dark nucleus D) Karyolysis: faint dissolved nucleus
Understand the Problem
The question is asking about the different nuclear changes that occur during necrosis. It lists several options that describe changes in the nucleus, and the user is expected to select all that apply to necrosis.
Answer
Karyorrhexis, Pyknosis, Karyolysis occur during necrosis.
Nuclear changes during necrosis include B) Karyorrhexis: nuclear fragmentation, C) Pyknosis: small dark nucleus, and D) Karyolysis: faint dissolved nucleus.
Answer for screen readers
Nuclear changes during necrosis include B) Karyorrhexis: nuclear fragmentation, C) Pyknosis: small dark nucleus, and D) Karyolysis: faint dissolved nucleus.
More Information
During necrosis, pyknosis is the condensation of the nucleus, karyorrhexis is its fragmentation, and karyolysis refers to the dissolution of the nucleus. These changes mark the progressive disintegration of the cell nucleus until it eventually dissolves.
Tips
Confusing necrosis with apoptosis: In apoptosis, similar nuclear changes occur but as part of a controlled process, whereas necrosis involves uncontrolled disintegration.
