GENERAL HISTOLOGY

Detailed explanation-1: -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).

Detailed explanation-2: -As seen with the electron microscope, the basement membrane is composed of two layers, the basal lamina and the reticular lamina. The underlying connective tissue attaches to the basal lamina with collagen VII anchoring fibrils and fibrillin microfibrils.

Detailed explanation-3: -noun. : a thin extracellular layer that sometimes lies below the basal lamina, is composed chiefly of collagenous fibers, and serves to anchor the basal lamina to underlying connective tissue.

Detailed explanation-4: -Answer and Explanation: The correct answer: The presence of a basement membrane is typical of most (a) epithelial tissues. The epithelial tissues are present in most of the regions of the body and there is a basement membrane as a basement layer of the epithelium.
