Shape & Structure
The pseudostratified columnar epithelium is a special simple columnar cell that appears to be stratified. However, upon closer inspection of the cell, we see that it only has one layer instead of the multiple layers like it's stratified counterpart. The actual shape of the cell itself consists of basal, fusiform, and columnar cells with only the columnar cells reaching the apical(free) surface, this makes it appear stratified due to the other cells (basal & fusiform) not reaching the free surface and the nuclei of these cells appearing at different levels. The ciliated version of pseudostratified columnar have many little hair-like projections called cilia on the apical surface that move along different substances in
