The simple columnar epithelium (Epi) is composed of tall cells with their ovoid nuclei located at the base of the cytoplasm. The lateral cell walls are not visible owing to the oblique cut of the thick section. (See a thinner perpendicular section of the same epithelium in Figure 1.16).

The connective tissue or lamina propria (LP) under the epithelium, the nuclei of spermatozoa (Z) and the long flame-like clusters of microvilli (M) at the apex of the epithelial cells are also identified.
