Question

Which of the following does not correctly describe stratified columnar epithelium?

1) It is a type of epithelial tissue.
2) It consists of multiple layers of columnar cells.
3) It is found in the lining of the respiratory tract.
4) It is found in the lining of the digestive tract.

Answer 1

The incorrect statement is that stratified columnar epithelium is found in the lining of the respiratory tract; this lining consists of pseudostratified columnar epithelium, not stratified.

Step-by-step explanation:

The statement that does not correctly describe stratified columnar epithelium is number 3, which states that it is found in the lining of the respiratory tract.

Instead, the respiratory tract is lined with pseudostratified columnar epithelium, which seems to have multiple layers due to the arrangement of nuclei at different levels, but is actually a single layer of cells all in contact with the basal lamina. Stratified columnar epithelium, on the other hand, is found in some ducts of glands and consists of multiple layers of column-like cells.
