- Thus, an epithelium with a single layer of flattened cells is called a simple squamous epithelium. If the shape of the cells is not identical in the various layers of a stratified epithelium, it is the outermost layer (ie at the free surface) that determines the classification.or example, the epidermis is called a stratified squamous epithelium even though the cells in the basal layers are cuboidal, because the outermost layer of cells is squamous. Images of different types of epithelia are shown below.

Squamous Epithelial Cells in Urine In contrast, the epithelial cells seen on the skin are squamous epithelial cells, that is, they are large and flat. Hence, the presence of columnar epithelial cells in the urine indicates the presence of a pathological condition associated with the kidneys or some other part of the urinary tract. However, if squamous cells are seen, then the urine is contaminated. This can occur in many cases.

What Is Epithelial Tissue? - Function, Types & Structure Pseudostratified columnar epithelium is a type of tissue that has a single layer of cells arranged in a fashion that appears to be stratified, whereas transitional epithelial tissue is an elastic-like epithelial tissue that swells, contracts, and changes shape as necessary.ence, something that is 'pseudo' (in our case, pseudo-stratified) looks to be stratified when it's actually not. Since the only alternative to stratified epithelial tissue is simple epithelial tissue, you know that the pseudostratified columnar epithelium has got to be only one layer of columnar cells.

Pseudostratified Columnar Epithelium A pseudostratified columnar epithelium is a special type of simple epithelium that consists of a falsely-stratified single layer of epithelial cells resting on a basement membrane. Many, if not most, of the cells, are columnar. Ciliated pseudostratified columnar epithelium (Respiratory Epithelium) lines the upper respiratory tract. 2  Nonciliated pseudostratified columnar epithelium lines the epididymis of the male reproductive system.

24 4.2 Epithelial Tissue Simple epithelial tissue is organized as a single layer of cells and stratified epithelial tissue is formed by several layers of cells. Simple Epithelium. The shape of the cells in the single cell layer of simple epithelium reflects the functioning of those cells. The cells in simple squamous epithelium have the appearance of thin scales. Squamous cell nuclei tend to be flat, horizontal, and elliptical, mirroring the form of the cell.

- Stratified columnar epithelium is rare but can be found in salivary glands. It consists of a layer of columnar epithelium resting on top of at least one other layer of epithelial cells, which may have any shape (columnar, cuboidal, or squamous). Stratification in cuboidal tissue has a secretory function.1  Simple columnar epithelia. 2  Stratified columnar epithelia.olumnar epithelia are epithelial cells whose height are at least four times their width. Columnar epithelia are divided into simple (or unilayered), and stratified (or multi-layered). These cells are tall and are arranged like pillars.

Stratified Squamous Epithelium Stratified Squamous Epithelium. A stratified squamous epithelium consists of more than one (typically many) layers, or strata, of epithelial cells (see figure). The basal layer of epithelial cells are small and cuboidal-to-columnar; the cells gradually become larger and more squamous as the cells migrate from the basal layer to the apical layer.

Stratified Squamous Epithelium Numerous cell layers, the most superficial of which is squamous, characterize stratified squamous epithelium. The function of this type of tissue is protection.he basal layer of this tissue is cuboidal, and becomes increasingly flattened as it reaches the surface. Stratified squamous epithelia can be keratinized or nonkeratinized, depending on the location it is found in. Keratinized epithelium, also called cornified is composed of numerous layers of dead squamous cells.

Epithelium â Functions and Types of Epithelial Tissue Thus, an epithelium with a single layer of flattened cells is called a simple squamous epithelium. If the shape of the cells is not identical in the various layers of a stratified epithelium, it is the outermost layer (ie at the free surface) that determines the classification.f the cells have a flattened shape, the epithelium is called squamous; if the cells have about the same height, width and depth, it is called cuboidal; if the height of the cells exceeds their width, it is called columnar.

What is Stratified Columnar Epithelium? The principle structural types are simple and stratified. Simple epithelium has only one layer of cells, while stratified epithelium has two or more layers. The form and function classifications of epithelial tissue are cuboidal, squamous, and columnar. rare type of this tissue, stratified columnar epithelium, is only found in a few places in the body, including parts of the anus, conjunctiva in the eye, uterus, and pharynx. Epithelial tissue is classified in two ways: based on structure, and based on form and function.
