Simple squamous epithelium A simple squamous epithelium is a single layer of flat cells in contact with the basal lamina (one of the two layers of the basement membrane) of the epithelium.This type of epithelium is often permeable and occurs where small molecules pass quickly through membranes via filtration or diffusion.Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is required. Cells are flat with flattened/rounded nucleus.It is also called pavement epithelium due to its tile-like appearance.his type of epithelium is often permeable and occurs where small molecules pass quickly through membranes via filtration or diffusion.

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.

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 Epithelium (epi- + thele + -ium) is one of the four basic types of animal tissue. The other three types are connective tissue, muscle tissue and nervous tissue.Epithelial tissues line the cavities and surfaces of blood vessels and organs throughout the body. There are three principal shapes of epithelial cells: squamous, columnar, and cuboidal.These can be arranged in a single layer of cells as simple epithelium, either squamous, columnar or cuboidal, or in layers of two or more cells deep as stratified (layered), either squamous, columnar or cuboidal.ll epithelia is usually separated from underlying tissues by an extra cellular fibrous basement membrane. The lining of the mouth, lung alveoli and kidney tubules all are made of epithelial tissue. The lining of the blood and lymphatic vessels are of a specialised form of epithelium called endothelium.

Stratified Squamous Epithelium 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 epithelia are specialized to withstand the mechanical stresses of abrasion. stratified squamous epithelium consists of more than one (typically many) layers, or strata, of epithelial cells (see figure).

- The most prevalent of the stratified epithelia is the squamous variety. As a keratinized or waterproofed component of the skin, stratified squamous epithelium provides substantial protection against friction, microbial invasion and dessication.tratified epithelia are found covering the exterior body surfaces and lining portions of the body tracts where friction phenomena occur. A multilayered epithelium allows deeper cells to replace the more superficial cells as they are damaged or cast off from the epithelial free surface.

Epithelial Tissues Simple squamous epithelium. This type is composed of a single layer of flattened, scale-or plate-like cells. It is quite common in the body. The large body cavities and heart, blood vessels and lymph vessels are typically lined by a simple squamous epithelium.pithelia are avascular, but all epithelia grow on an underlying layer of vascular connective tissue. The connective tissue and the epithelium are separated by a basement membrane. Epithelium covers all free surfaces of the body. Epithelium also lines the large internal body cavities, where it is termed mesothelium.
