From Wikipedia, the free encyclopedia

Columnar epithelia are epithelial cells whose heights are at least four times their width. Columnar epithelia are divided into simple (or unilayered), and stratified (or multi-layered).

• Simple columnar epithelia
• Stratified columnar epithelia
• Pseudostratified columnar epithelia
