Difference between basal lamina and basement membrane?
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.
What is the difference between the basal lamina and the basement membrane in terms of their structure and function?
The basal lamina is a thin layer of extracellular matrix secreted by epithelial cells, while the basement membrane is a thicker structure that includes the basal lamina along with additional layers produced by connective tissue cells. The basal lamina provides structural support and acts as a barrier, while the basement membrane also serves as a filter and plays a role in cell signaling and tissue organization.
What is the difference between the basement membrane and the basal lamina in terms of their structure and function?
The basement membrane is a complex structure made up of two layers, the basal lamina and the reticular lamina. The basal lamina is the innermost layer of the basement membrane and is composed of proteins like collagen and laminin. It provides structural support and acts as a barrier between different tissues. The basal lamina also plays a role in cell adhesion and signaling. On the other hand, the basal lamina is a thin layer of extracellular matrix that is found underneath epithelial and endothelial cells. It helps anchor these cells to the underlying connective tissue and regulates the passage of molecules between the cells and the surrounding tissue.
What type of epithelium lack a basal lamina?
Hepatocytes and endothelia (eptihelium lining vessels)
What are ten different cell parts in a human epithelial cell?
The cell parts of an epithelial cell include; apical and basal regions and a basement membrane (basal lamina). Epithelial cells are held together by desmosomes, adherens, tight junctions and gap junctions.
What is the name of the non cellular layer that attaches epithelial tissue to other layers?
The basal lamina, made up of the lamina densa and the lamina lucida. In cases where to layers of epithelium abut one another, the basal lamina is referred to as a basement membrane.

What is the basal and reticular lamina?
The basal lamina is a thin extracellular layer that underlies epithelial and endothelial cells, providing structural support and aiding in cell adhesion. The reticular lamina, found beneath the basal lamina in some tissues, is primarily composed of collagen fibers and helps anchor the basal lamina to underlying connective tissue. Together, the basal and reticular laminae form the basement membrane, which plays a crucial role in tissue organization and function.
How is junctional epithelium attached to enamel?
The junctional epithelium attaches to enamel by means of internal basal lamina .
What is the connective tissue found beneath all types of epithelium?
The connective tissue found beneath all types of epithelium is called the basement membrane. It provides structural support to the overlying epithelial cells and helps in anchoring them to the underlying tissues. The basement membrane also plays a role in filtration and diffusion of substances between the epithelial cells and the underlying tissues.

Does epithelial tissue have a basement membrane?
No. All epithelial sheets rest upon and are supported by connective tissue Just deep to the basal lamina is the reticular lamina a layer of extracellular material containing a fine network of collagen protein fiber that belongs to the underlying connective tissue. Together the two laminae form the basement membrane.
Where is the basal lamina of axon and ganglion cells?
I would to know that
What two factors determine the distance from the free surface to the basal surface in epithelial tissue?
The presence of different types of cells and their positioning within the epithelial layer determine the distance from the free surface to the basal surface in epithelial tissue. Additionally, the function of the epithelial tissue in a specific organ or structure can influence the thickness of the tissue layer.
