For tissues with epithelial surfaces, which orientation best exposes all tissue layers with epithelium on top?

When you want to visualize all tissue layers with the epithelial surface on top, the best approach is an oblique, flat plane that is cut slightly diagonally across the block. This orientation places the epithelium at the top of the view while slicing through the deeper layers beneath it, so you can see the full stack from surface epithelium through the underlying connective tissue and other strata in a single section. Cuttings that are on end or show a lumen in cross section tend to emphasize only a narrow edge or a circular cross-section, which hides some layers. A parallel arrangement wouldn’t reveal the vertical layering in a way that shows the epithelium along with the layers beneath.
