What is a ciliated epithelium, explain its structure and function?

In this tissue the epithelial cells bear at their free ends thin elongated cyto­plasmic processes called Cilia (Sing cilium). Each cilium arises from a minute particle called basal granule or blepharoplast that lies internal to the cell membrane.

In between the ciliated epithelial cells are present mucous secreting goblet cells. The mucous spreads over the epithelium as a thin coating. The cilia have a beating action (move like the lashes of a whip) as a result of which the mucous and other substances are transferred over the epithelium from one place to another.

The cilia also help in shifting small solid particles entangled in the mucous. In this tissue the epithelial cells bear at their free ends thin elongated cyto­plasmic processes called Cilia (Sing cilium).
