what is the main structural difference between simple and stratified epithelium?
476543
Structure. The biggest difference between simple and stratified tissue is that simple tissue is one layer thick while stratified tissue is multi-layered. All epithelial tissue rests on a basement membrane, which is a thin protective membrane located on the outside of the tissue.

The stomach wall, with simple columnar epithelium visible as a lining at the top. A simple columnar epithelium is a columnar epithelium that is uni-layered. In humans, a simple columnar epithelium lines most organs of the digestive tract including the stomach, small intestine, and large intestine.

Stratified squamous epithelium: This tissue is the stuff you see every day — your outer skin, or epidermis. This multilayered tissue has squamous cells on the outside plus deeper layers of cuboidal or columnar cells.

['There are three principal cell shapes associated with epithelial cells: squamous epithelium, cuboidal epithelium, and columnar epithelium.', 'There are three ways of describing the layering of epithelium: simple, stratified, and pseudostratified.']

The alveoli of lungs where gases diffuse, segments of kidney tubules, and the lining of capillaries are also made of simple squamous epithelial tissue. The mesothelium is a simple squamous epithelium that forms the surface layer of the serous membrane that lines body cavities and internal organs.

A stratified epithelium consists of multiple layers of cells in which only the basal layer is attached to the basement membrane. A simple epithelium which appears to be stratified is classified as "pseudostratified" (the nuclei are in different layers, but all the cells are in contact with basement membrane).

However there are two main differences between these two epithelia. With regard to the epithelial cells themselves, the stretched transitional epithelium has considerably fewer cell layers than the stratified squamous epithelium and the immediately underlying cells tend to be cuboidal rather than squamous.

Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei. ... This epithelium is associated with filtration and diffusion. This tissue is extremely thin, and forms a delicate lining.

Answer and Explanation: Stratified, also called compound, epithelial tissue provides the best protection against unwanted organisms or substances.

This type of epithelium is often permeable and occurs where small molecules need to pass quickly through membranes via filtration or diffusion. Simple squamous epithelia are found in capillaries, alveoli, glomeruli, and other tissues where rapid diffusion is required. Cells are flat with flattened and oblong nuclei.

Simple squamous epithelia are tissues formed from one layer of squamous cells that line surfaces. Squamous cells are large, thin, and flat and contain a rounded nucleus. Like other epithelial cells, they have polarity and contain a distinct apical surface with specialized membrane proteins.

Stratified squamous epithelia are found in nearly every organ system where the body comes into close contact with the outside environment – from the skin to the respiratory, digestive, excretory and reproductive systems. They also protect the body from desiccation and water loss.

Transitional epithelia are found in tissues that stretch, and it can appear to be stratified cuboidal when the tissue is relaxed, or stratified squamous when the organ is distended and the tissue stretches. It is sometimes called urothelium since it is almost exclusively found in the bladder, ureters and urethra.

Stratified columnar epithelia - only the superficial cells are columnar in shape. ... Explain why the pseudostratified columnar epithelium is not truly stratified. Every cell contacts the basal lamina, the distances between the cell nuclei and the exposed surface vary causing an illusion.

The main difference between epithelial tissue and connective tissue is their function and the cells they are comprised of. Epithelial tissue consists of three cell types; squamous, cuboidal and columnar. ... Connective tissue supports, connects, binds, or separates other tissues or organs.

A stratified squamous epithelium consists of squamous (flattened) epithelial cells arranged in layers upon a basal membrane. Only one layer is in contact with the basement membrane; the other layers adhere to one another to maintain structural integrity.
