Cuboidal epithelium is a single layer of cube shaped cells with a centrally located nucleus. Ciliated epithelium is a type of bodily tissues that is lined with ciliated cells, which are basically cells that have small, hair-like protrusions known as cilia that can either help the cells move along the tissue or can help debris and waste move along the surface of the cells. Columnar epithelial cells occur in one or more layers.
The cells are elongated and column-shaped. The nuclei are elongated and are usually located near the base of the cells. Squamous cells have the appearance of thin, flat plates. The shape of the nucleus usually corresponds to the cell form and help to identify the type of epithelium. Keratinized squamous epithelium consists of multiple layers of squamous cells.
The apical layer of cells are dead and filled with the protein keratin.
