1. single layer of tall and short columnar shape ( height of some cells are more and height of some cells are less but all cells rest on basement membrane )cells rest are on basement membrane
2. cell contain single centrally place oval nuclei , located near the basal region
3. Level of nuclei are different so it is look like stratified epithelium but all cells are rest on basement membrane . it stratified epithelium only basally place cells layer rest on basement membrane . other cells layer rest on previous cell layer .
Ex: lining epi of trachea, bronchi, epididymis, vas deferens
