Introduction
Epithelial tissues = covering or protective tissues in the animal body.

Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Simple squamous epithelium | Single layer of flat cells in contact with basement membrane. |

| Columnar epithelium | The length of the cells is much more than their width, arranged like columns. |
| Ciliated columnar epithelium | Rectangular in shape and have hair-like protrusions called cilia. |
| Cuboidal epithelium | The length of the tissue is almost equal to their width, appearing like a square. |
