Epithelium or epithelial tissue is a thin, continuous, protective layer of cells with little extracellular matrix.An example is the epidermis, the outermost layer of the skin.
Simple cuboidal epithelium is a type of epithelium that consists of a single layer of cuboidal (cube-like) cells which have large, spherical and central nuclei.. Simple cuboidal epithelium is found on the surface of ovaries, the lining of nephrons, the walls of the renal tubules, parts of the eye and thyroid, and in salivary glands.
The corneal epithelium (epithelium corneae anterior layer) is made up of epithelial tissue and covers the front of the cornea.It acts as a barrier to protect the cornea, resisting the free flow of fluids from the tears, and prevents bacteria from entering the epithelium and corneal stroma.
A simple squamous epithelium, also known as pavement epithelium and tessellated epithelium, is a single layer of flattened, polygonal cells in contact with the basal lamina (one of the two layers of the basement membrane) of the epithelium. [1]
The intestinal epithelium is the single cell layer that forms the luminal surface (lining) of both the small and large intestine (colon) of the gastrointestinal tract.Composed of simple columnar epithelium its main functions are absorption, and secretion.
Cell junctions [1] or junctional complexes are a class of cellular structures consisting of multiprotein complexes that provide contact or adhesion between neighboring cells or between a cell and the extracellular matrix in animals. [2]
Some tests which detect cancer could be called "screening for epithelial dysplasia". The principle behind these tests is that physicians expect dysplasia to occur at the same rate in a typical individual as it would in many other people.
The vaginal epithelium is the inner lining of the vagina consisting of multiple layers of cells. [1] [2] [3] The basal membrane provides the support for the first layer of the epithelium-the basal layer.
