Basement membranes attach layers of tissues in the body.
Layers of skin basement membrane. Basal lamina is visible only with the electron microscope and about 20 100 nm in. We introduce the structure of the basement membrane which underlies all epithelia. The basement membrane membrana basalis is a thin layer of basal lamina and reticular lamina that anchors and supports the epithelium and endotheliumepithelium is a type of tissue that forms glands and lines the inner and outer surfaces of organs and structures throughout the body.
Although once thought to be homogeneous it appears to consist of three layers that read more. Basal lamina reticular lamina most epithelial cells are separated from the connective tissue by a sheet of extracellular material called basement membrane. Learn how the basement membrane helps our skin counteract the effects of gravity and explore its various other functions in this lesson.
The basement membrane is usually visible with the light microscope. The stratum basale also called the stratum germinativum is the deepest epidermal layer and attaches the epidermis to the basal lamina below which lie the layers of the dermis. The basement membrane separates endothelium from pericytes and astrocytes two other cell types which regulate function of the neurovascular unit.
This surface may be epithelium skin respiratory tract gastrointestinal tract etc mesothelium pleural cavity peritoneal cavity pericardial cavity etc and endothelium blood vessels lymph. The cells in the stratum basale bond to the dermis via intertwining collagen fibers referred to as the basement membrane. The basement membrane of the capillaries similar to that which occurs in the lining of many other structures and organs is a continuous layer of hydrated collagen and glycopeptides.
It is formed by the association of two layers. The basement membrane is a thin fibrous extracellular matrix of tissue that separates the lining of an internal or external body surface from underlying connective tissue in metazoans animals. The basement membrane is composed of different extracellular matrix structural proteins eg collagen laminin.

The two layers of the skin which is the epidermis and the dermis are anchored to one another by a thin but complex layer of tissue known as basement membrane.
