Detailed explanation-1: -Basement membranes are a dense, sheet-like form of extracellular matrix (ECM) that underlie epithelia and endothelia, and surround muscle, fat and Schwann cells. Basement membranes separate tissues and protect them from mechanical stress.
Detailed explanation-2: -The specialized form of thin extracellular layer which anchors epithelial cells to underlying connective tissue is called basement membrane.
Detailed explanation-3: -Basement membranes function not only in anchoring adjacent cells and providing scaffolding during embryonic development, but also in migration, differentiation, and maintenance of the differentiated phenotype of associated epithelial or endothelial cells.
Detailed explanation-4: -The basement membrane is formed by a mixture of molecules, including type IV collagen (i.e., the structural protein found in the basement membrane, the lens of the eye, and the cochlea of the ear) primarily and laminin (i.e., a glycoprotein, or protein that contains oligosaccharide chains).
