pseu·do·strat·i·fied ep·i·the·li·uman epithelium that gives a superficial appearance of being stratified because the cell nuclei are at different levels, but in which all cells reach the basement membrane, hence it is classed as a simple epithelium.pseu·do·strat·i·fied ep·i·the·li·um (sū'do-strat'i-fīd ep'i-thē'lē-ŭm) An epithelium that gives a superficial appearance of being stratified because the cell nuclei are at different levels, but in which all cells reach the basement membrane. pseudostratified epitheliumEpithelium in which the bases of cells rest on the basement membrane but the distal ends of some do not reach the surface. Their nuclei lie at different levels, giving the appearance of stratification.
