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.

Pseudostratified ciliated
columnar epithelium
Notice how the nuclei are at
different levels- this indicates
pseudostratified. The cells are also
columnar shaped and ciliated
(arrow).

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
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.
