GENERAL HISTOLOGY

Detailed explanation-1: -Answer and Explanation: The correct answer is D. Pseudostratified columnar tissue. Pseudostratified columnar cells have irregular shapes and nuclei at different levels, giving the appearance of multiple layers.

Detailed explanation-2: -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-3: -Pseudostratified columnar epithelium is a type of epithelium that appears to be stratified but instead consists of a single layer of irregularly shaped and differently sized columnar cells. In pseudostratified epithelium, nuclei of neighboring cells appear at different levels rather than clustered in the basal end.

Detailed explanation-4: -Pseudostratified columnar epithelia are tissues formed by a single layer of cells that give the appearance of being made from multiple layers, especially when seen in cross section. The nuclei of these epithelial cells are at different levels leading to the illusion of being stratified.

Detailed explanation-5: -Epithelia composed of a single layer of cells is called simple epithelia; epithelial tissue composed of multiple layers is called stratified epithelia.
