2. Remember when answering to include features including whether the epithelium is ciliated, has a brush border or is keratinized. Be as detailed as possible. Start by identifying the location of the basement membrane and then focus on the just the epithelium.
3. Identify the epithelium and the cells indicated by *. L indicates lumen L L * * * *
4. L L * * * * Answer: Simple columnar with brush border (arrows). * Indicates goblet cells. BM- location of basement membrane Duodenum
5. Identify the type of epithelium.
6. Pseudostratified ciliated columnar epithelium Notice how the nuclei are at different levels- this indicates pseudostratified. The cells are also columnar shaped and ciliated (arrow). Answer: BM- location of basement membrane Trachea
7. Identify the type of epithelium
8. Transitional epithelium aka urothelium Answer: Notice how the cells closest to the lumen sit over top of the rest of the epithelial cells, these are umbrella cells (arrow). BM- location of basement membrane Ureter
9. Identify the epithelium indicated by arrow A and arrow B. L indicates lumen. University of Michigan, Virtual Microscopy Database L L L A A B B
10. Answer: A- simple squamous (single layer of flat cells) B- simple cuboidal (centrally placed nuclei in cube-shaped cells, single layer of cells) L indicates lumen. University of Michigan, Virtual Microscopy Database L L L A A B B BM- location of basement membrane Kidney
11. Identify the epithelium. *Note that the gaps between the dark pink lines (arrows) are artifact, they should be together as part of the epithelium.
12. Answer: Stratified squamous, keratinized BM BM BM BM- location of basement membrane Notice there are multiple layers of cells indicating stratified epithelium and the top cells are flat- squamous. The arrows indicated keratinized tissue, where the nuclei and other organelles have been lost. Skin
13. University of Michigan, Virtual Microscopy Database L Identify the epithelium surrounding the lumen (L).
14. BM- location of basement membrane University of Michigan, Virtual Microscopy Database L Answer: Simple squamous A single layer of flat/squamous cells (arrows) Vein BM BM
