Epithelial tissue always has an exposed outer surface anchored to connective tissue by a thin, non-cellular structure called the basement membrane.
<h3>What is the basement membrane? </h3>
Thin layers of a specialized extracellular matrix that form the supporting structure supporting the growth of epithelial and endothelial cells are called the basement membranes. They surround the muscle and fat cells and the Schwann cells of peripheral nerves.
There is one common denominator regarding the basement membrane. This is because they are always in close opposition to cells.
It has been well demonstrated that basement membranes are not only for the provision of mechanical support and for dividing the tissues into compartments but also influence cellular behavior.
Collagen IV,laminin-entactin/nidogen complexes, and proteoglycans are the major molecular components of the basement membrane.
Therefore, epithelial tissue is anchored to connective tissue by a thin, non-cellular structure called the basement membrane.
