Improper processing of tissue may result in which of the following?

• A. Only Clean Sections
• B. Mushy Sections Or Sections With Chatter
• C. Perfectly Flat Ribbons
• D. No Effect

Answer: (B)

Improper processing disrupts the paraffin infiltration and solid support the tissue needs to cut cleanly. When dehydration, clearing, or infiltration steps are not done correctly, the block becomes too soft or unevenly hardened, so the tissue cannot be cut into stable, uniform ribbons. That softness leads to mushy sections. If the block isn’t properly infiltrated, the tissue isn’t adequately supported by paraffin, causing the knife to interact with the tissue surface in a way that creates chatter marks. These artifacts are classic signs that the processing steps were off. In properly processed tissue, sections are clean and ribbons lie flat with no chatter; saying there’s no effect simply isn’t true because processing quality directly impacts section quality.
