The Parthenon-like structure (IMAGE)
Caption
Most of the volume of epithelial cell bodies containing nuclei are aligned as a monolayer on the apical (upper) side. They extend pillarlike cell processes in a basal (downward) direction. At the basal (lower) side, the cytoplasm of epithelial cells spread planarly, creating a thin layer. Macrophage-like cells are found in the cavities between pillars.
