A one-layer trick
Pseudo means fake. Stratified means in layers. So this lining is fake layers!
Every cell sits on the same bottom sheet. But some cells are tall and reach the top, and some are short and stay low. Their nuclei end up at different heights, so under a microscope it looks like many layers.
You have this lining in your nose and your windpipe, the tube that carries air to your lungs.
Wow!
The tall cells have hundreds of tiny hairs on top called cilia. They beat together, a bit like a crowd doing the wave.
