Stratified Epithelial Tissue 
Cells are arranged in rows or sheets MULTIPLE cell layers thick.
Read the descriptions of the different stratified epithelia below
and select the best choice using all the clues you can find.

Stratified Squamous

TOP LAYER CELLS are all squamous 
FLAT AND THIN like tiles or pancakes.

Nuclei tend to be FLATTENED IN THE TOP LAYERS.

Cells in the lower layers may be any shape.


Stratified Cuboidal

TOP LAYER CELLS are all cuboidal 
EQUALLY TALL & WIDE (like SQUARES.)

Nuclei tend to be roundish IN THE TOP LAYER.

Cells in the lower layers may be any shape.


Stratified Columnar

TOP LAYER CELLS are all columnar 
TALLER THAN THEY ARE WIDE (like RECTANGLES.)

Nuclei tend to be oval IN THE TOP LAYER.

Cells in the lower layers may be any shape.
Transitional

TOP LAYER CELLS tend to be MUCH LARGER
THAN LOWER CELLS
and tend to look like huge fluffy pillows or clouds
(at least their apical portions).

Nuclei tend to be fairly large and round or oval
throughout all layers.

Cells in the lower layers may be round or elongated.
