Webb9 nov. 2024 · Simple epithelia have a single layer of cells, while stratified epithelia have multiple layers. The cell layers may be arranged in a variety of ways, depending on the type of epithelium. Epithelium, one of the four types of human tissues, is a tiny part of the body. It is produced by cells within an extracellular matrix (ECM). WebbEpithelial cells can also be organized into one or multiple layers. There are two types of epithelial tissues with only one layer of cells: simple and pseudostratified. Simple epithelial tissues have one layer of cells in a single line; an example of this tissue type is simple cuboidal epithelium.
