Clara cells are found in the ciliated simple epithelium.

Lancelets have no respiratory system, breathing solely through their skin, which consists of a simple epithelium.

Epithelial tissue that is only one cell thick is known as simple epithelium.

The outer body wall consists of connective tissue, muscle fibres, and a simple epithelium directly underlying the tunic.

Microscopically, the cyst lining consists of a simple epithelium with cilia that may be columnar or flat.

The body consists of an outer layer of simple epithelium enclosing a loose sheet of cells.

Simple epithelium is one cell thick, that is, every cell is in direct contact with the underlying basement membrane.

Within the middle ear the simple epithelium gradually transitions into ciliated pseudostratified epithelium lining the Eustachian tube now known as the pharyngotympanic tube becoming continuous with the respiratory epithelium in the pharynx.

The term pseudostratified is derived from the appearance of this epithelium in section which conveys the erroneous (pseudo means false) impression that there is more than one layer of cells, when in fact this is a true simple epithelium since all the cells rest on the basal lamina.
