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 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 basement membrane binds epithelial tissue to underlying connective tissue. It provides structural support, filtration, and helps regulate the exchange of molecules between the epithelial cells and the underlying tissues.

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.
The membranes that do not contain gland cells are called basement membranes. These basement membranes line the interiors of blood vessels and the skin.
Squamous cell carcinoma
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 basement membrane binds epithelial tissue to underlying connective tissue. It provides structural support, filtration, and helps regulate the exchange of molecules between the epithelial cells and the underlying tissues.
The bladder is lined with transitional epithelial cells, which are also known as urothelial cells. These cells are unique in that they can stretch to accommodate the volume of urine in the bladder and then contract to expel the urine during urination.
