A higher-power magnification, such as that afforded by an electron microscope, is needed to see the intricacies of the basement membrane. The basement membrane has numerous functions, including roles in mechanical support and angiogenesis; Created with BioRender.com. Flashcards. Submucosa. The plasma membrane acts as a dynamic interface between the cell and its surroundings. (1) Polysaccharides: The technique is commonly used to identify polysaccharides- these macromolecules are composed of monosaccharide units joined by covalent bonds. It is a selective barrier that protects tissues and is often involved in absorption or secretion. Histology. As with every other epithelium, it lies on the basement membrane. The basement membrane is a thin, pliable sheet-like type of extracellular matrix, that provides cell and tissue support and acts as a platform for complex signalling.

The basement membrane sits between epithelial tissues including mesothelium and endothelium, and the underlying connective tissue. Capillary Capillaries contain a single layer of endothelial cells and their basement membrane. Released aldehydes reduce the silver to a visible metallic silver (black). Basement membranes support epithelial and endothelial cells, prevent the passage of proteins, and generate histologically distinct compartments in the body. SHOWING Match.
