What is a characteristic of stratified columnar epithelium?

Stratified columnar epithelium is characterized by having multiple layers of cells, with the topmost layer being columnar in shape. In this context, the statement about containing few layers of rectangular cells accurately captures the essence of this type of epithelium. While it does have fewer layers compared to other stratified types, it retains a primary columnar shape at the surface, distinguishing it from other epithelial types that may incorporate various shapes in greater numbers.

The presence of its structure allows it to provide protection and secretion, often found in areas such as the male urethra and certain large ducts of glands. The nature of the stratified arrangement helps in withstanding wear and tear in areas subject to friction, underpinning its functional significance. Other shapes or arrangements, such as cuboidal, do not accurately reflect the nature of stratified columnar epithelium, highlighting why this characterization is correct.
