| Correct! Pseudostratified ciliated columnar epithelium consists of columnar cells that are packed side-by-side-with smaller cuboidal cells. This arrangement looks like two layers at first glance, but is really one (columnar) cell thick. The tallest of all of the epithelial cells, columnar cells are perfectly designed for product creation, storage, and release, as well as absorption of items. Thus, the psedostratified variety can be seen mixed with simple columnar layers lining the entire gastrointestinal (G.I.) tract from the stomach down to the lower colon (without cilia), and parts of the respiratory tract and the female's fallopian tubes (in it's ciliated form). Goblet cells are scattered in these areas to provide mucus for protection. Lets return to the original question. |
