Many differently formed epithelial cells form a multi-layered squamous epithelium.
Without ceratinization it occurs for example inside the oral cavity the throat and inside the vagina.
WITH ceratinization it forms the epidermis, the vessel-less outer layer of the skin.
The epithelium is divided from the underlying tissue by a basal membrane or lamina.
Epithelial cells can be squamous, cuboid, or columnar.
