Several key features distinguish simple columnar epithelial cells:
Microvilli: These are small, finger-like projections on the apical surface of the cells, which increase the surface area for absorption. Cilia: In some locations, such as the fallopian tubes, the apical surface of these cells is ciliated, allowing for the movement of particles or fluids over the epithelial surface. Goblet Cells: These are mucus-secreting cells interspersed among the columnar cells, providing lubrication and protection.
