Detailed explanation-1: -Stratified: A stratified epithelium is made up of more than one layer of cells. Pseudostratified: A pseudostratified epithelium is made up of closely packed cells that appear to be arranged in layers because they’re different sizes, but there’s actually just one layer of cells.
Detailed explanation-2: -Stratified epithelium consists of two or more cell layers. There is a great amount of variability between the layers due to various cellular shapes and heights. The three types of cellular shapes are squamous, cuboidal, and columnar.
Detailed explanation-3: -The types of epithelia are classified by the shapes of cells present and the number of layers of cells. Epithelia composed of a single layer of cells is called simple epithelia; epithelial tissue composed of multiple layers is called stratified epithelia.
Detailed explanation-4: -Stratified squamous epithelia are tissues formed from multiple layers of cells resting on a basement membrane, with the superficial layer(s) consisting of squamous cells. Underlying cell layers can be made of cuboidal or columnar cells as well.
Detailed explanation-5: -Stratified columnar epithelium is a rare type of epithelial tissue composed of column-shaped cells arranged in multiple layers. It is found in the conjunctiva, pharynx, anus, and male urethra. It also occurs in embryo.
