Question

A activity to identify the epithelial tissue

Answer 1

These slides show simple cuboidal epithelium, lining tubules in the kidney. The tubules are cut in all different orientations; look for a region toward the middle of the slide where the tubules are cut more or less in longitudinal section in slide 9 [example](link is external) or slide 210,[example](link is external) and appear as parallel wavy rows (at 4x magnification). Look for a favorable area where you can see a space (the tubule lumen) lined on either side with simple cuboidal epithelium. Note also that there is very little other tissue between tubules, so that you often see two rows of cuboidal epithelia from adjacent tubules back to back. In other parts of the section, look for tubules in cross-section in slide 9[example](link is external) or slide 210 [example](link is external) where the lumen will be surrounded by a circle of cells.
