There is no other specific type of cell called an epithelial cell. Epithelial cell itself is a broad category encompassing various types of cells that form epithelium, a type of tissue that covers the surfaces of the body, lines internal cavities and organs, and forms glands.

Here's a breakdown:

* Epithelial tissue: This is the tissue type. It's classified based on the shape of the cells and the number of layers. Examples include:

* Squamous epithelium: Flattened cells, found in blood vessels and alveoli of the lungs.

* Cuboidal epithelium: Cube-shaped cells, found in glands and kidney tubules.

* Columnar epithelium: Tall, column-shaped cells, found in the lining of the stomach and intestines.

* Epithelial cells: These are the individual cells that make up epithelial tissue.

So, when someone refers to "epithelial cells," they are simply referring to the cells that make up epithelium, not a specific cell type.
