SIMPLE EPITHELIA

Simple epithelia are made up of a single layer of cells of the same size, and therefore all cells sit on the basal lamina (and all nuclei are arranged in a single row). According to the cell shape they are classified as:

- Simple squamous epithelium,
- Simple cuboidal epithelium,
- Simple columnar epithelium.
