Is pseudostratified epithelia commonly keratinized

Pseudostratified epithelia are typically not keratinized; they are primarily found in the respiratory tract, where they are ciliated and contain mucus-secreting goblet cells. This type of epithelium functions to trap and move particulate matter out of the airways. However, there are some variations, such as in certain areas of the male reproductive system, where keratinization may occur, but it is not the norm for pseudostratified epithelium overall.
