A section with chatter may be the result of which condition?

Explanation:
Chatter marks on a microtomy section occur when the knife struggles to slice the tissue cleanly. The most common cause is a dull blade—the worn edge increases friction and the knife edge doesn’t shave smoothly, so it vibrates against the tissue as it moves. That vibration leaves the fine, repetitive ridges and waviness you see as chatter in the section. A sharp blade cuts with less resistance, allowing the tissue to glide and produce a smooth surface, so chatter is minimized. Proper processing helps ensure the tissue has the right firmness for cutting, but it doesn’t cause chatter the way a dull edge does.
