Basement membrane

basement membrane The thin extracellular layer composed of fibrous elements, proteins, and space-fill­ing molecules. That attaches the epithelium tissue to the underly­ing connective tissue.(which forms the superficial layer of skin and some organs and the inner lining of blood vessels, ducts, body cavities, and the interior of the respiratory, diges­tive, urinary, and reproductive systems). Basement membrane is made up of a superficial basal lamina. Produced by the overlying epithelial tis­sue, and an underlying reticular lamina. Which is the deeper of two layers and produced by the underlying connective tissue. It is the layer of tissue that cells “sit” or rest on.
