▶Pseudostratified Epithelium though comprising of single layer of epithelium ... it's nuclei are positioned in such a manner that it looks multilayered....

▶it's cells are columnar and unequal in size

▶the long cells extends upto free surface but the small cells do not

▶long cells have oval nuclei but short cells have round nuclei

=>thus ... nuclei lie at different levels... so even though it is single layered appears to be multi layered
