MICROANATOMY

Detailed explanation-1: -The primary function of the basement membrane is to anchor down the epithelium to its loose connective tissue (the dermis or lamina propria ) underneath. This is achieved by cell-matrix adhesions through substrate adhesion molecules (SAMs).

Detailed explanation-2: -Opposite the free surface, the cells are attached to underlying connective tissue by a non-cellular basement membrane. This membrane is a mixture of carbohydrates and proteins secreted by the epithelial and connective tissue cells.

Detailed explanation-3: -The basal lamina helps to attach and anchor the cells to the underlying connective tissue. Proteins (integrins and proteglycans) in the cell membranes attach to proteins in the basal lamina, which in turn is linked to the extracellular matrix of connective tissue.

Detailed explanation-4: -Answer and Explanation: The structure which attaches the epithelium to deeper connective tissue is known as the Basal Lamina. The cells of the epithelial tissue are firmly attached to the underlying connective tissue, known as the dermis, by a thin, noncellular basement membrane or the basal lamina.
