No not all cells touch the basement membrane. Pseudostratified epithelium is composed of cells that touch the basement membrane.
basement membrane
The inner surface of epithelial tissue rests on a basement membrane, which is a thin layer of extracellular matrix secreted by the epithelial cells themselves. This basement membrane provides structural support and helps anchor the epithelial tissue to underlying connective tissue.
The surface of epithelial cells that faces the basement membrane is called the basal surface. This surface anchors the epithelial tissue to the underlying connective tissue and is involved in cell signaling and nutrient exchange. The basement membrane itself is a thin, fibrous layer that provides structural support and regulates the movement of molecules between the epithelium and the underlying tissues.
The membranes that do not contain gland cells are called basement membranes. These basement membranes line the interiors of blood vessels and the skin.
No, the basement membrane is not a living layer. It is a thin layer of extracellular matrix that separates and anchors epithelial and endothelial cells to the underlying connective tissue.

The basal membrane is a specific type of basement membrane found in epithelial tissues. The basement membrane is a thin, sheet-like structure that provides support and separates different tissue layers. The basal membrane is a specialized part of the basement membrane that is located adjacent to the basal surface of epithelial cells.

No, the basement membrane is not a living layer. It is a thin layer of extracellular matrix that separates and anchors epithelial and endothelial cells to the underlying connective tissue.
Cells with nuclei located near the basement membrane typically compose the basal layer of epithelial tissues. These cells are responsible for anchoring and supporting the epithelial tissue above, and they play a role in cell regeneration and repair.
The thin epithelial cells connected to the basement membrane are called simple columnar epithelial tissue because they consist of a single layer of cells that are taller than they are wide. They appear rectangular or column-like when seen in cross-section, giving them their name.

The term "basal lamina" is usually used with electron microscopy, while the term "basement membrane" is usually used with light microscopy. The structure known as the basement membrane in light microscopy refers to the stained structure anchoring an epithelial layer. This encompasses the basal lamina secreted by epithelial cells and typically a reticular lamina secreted by other cells.
The membrane that underlies and supports epithelial tissues is called the basement membrane. It is composed of a thin layer of extracellular matrix, which provides structural support and anchorage for the epithelial cells. The basement membrane also plays a crucial role in filtration, cell signaling, and tissue regeneration.
