All cells in the ciliated columnar epithelium reach the basement membrane, but only cells that reach the free surface have cilia.
<h3>What is an
epithelium?</h3>
An epithelium is a specialized layer of cells that play different roles in the organism (e.g., transport of substances, digestion, etc).
Epithelia are one of the four types of tissues that form the body, which also include connective tissue, muscle tissue, and nervous tissue.
The ciliated columnar epithelium is a special class of epithelium that contain cilia that are used to move substances across their cellular surfaces.
In conclusion, all cells in the ciliated columnar epithelium reach the basement membrane, but only cells that reach the free surface have cilia.
