Question

Some simple columnar and pseudostratified columnar epithelia have ________ cells, which produce a protective mucous coating over the mucous membranes.

Answer 1

Goblet cells are those secretory cells or unicellular glands, which make and expel mucus can be found in simple columnar and pseudostratified columnar epithelia.

What are goblet cells?

Characteristics of goblet cells

• Its main function is to secrete mucus, which protects and lubricates the inner surface of simple columnar and pseudostratified columnar epithelia.

Therefore, we can conclude that goblet cells are mucus-secreting cells present in epithelial linings.
