GENERAL HISTOLOGY

Detailed explanation-1: -The main difference between simple and stratified epithelium is that simple epithelium is composed of a single layer of cells while stratified epithelium is composed of multiple layers of cells.

Detailed explanation-2: -Simple: A simple epithelium means that there’s only one layer of cells. Stratified: A stratified epithelium is made up of more than one layer of cells.

Detailed explanation-3: -Stratified squamous keratinising epithelium There are around 8-10 layers of cells. It’s difficult to see the basal lamina in the region of the dividing cells, in the basal layer. Notice how the cells become more flattened towards the top (apical) layer.

Detailed explanation-4: -Simple squamous epithelium cells are flat in shape and arranged in a single layer. This single layer is thin enough to form a membrane that compounds can move through via passive diffusion.

Detailed explanation-5: -Simple epithelia are defined as epithelia which are one cell layer thick – i.e. every cell attaches to the basement membrane. The basement membrane is a thin but strong, acellular layer which lies between the epithelium and the adjacent connective tissue. It is sometimes referred to as the “basal lamina”.
