Stratified epithelium is named for the shape of the cells
forming the outermost layers.
ed squamous epithe-
consists of many layers of cells, making this tissue rela-
tively thick. Cells nearest the free surface are ﬂ attened the
most, whereas those in the deeper layers, where cell division
occurs, are cuboidal or columnar. As the newer cells grow,
older ones are pushed farther and farther outward, where
