1.4 Epididymis magnified 300 times

Version française

Higher-power view (×300) showing details of the simple columnar epithelium of the epididymal duct.

Top, centre: The plane of cut is perpendicular to the epithelium (*), which is 100 µm thick. The long filamentous projections (red arrowheads) at the apex of the epithelial cells correspond to non-motile bundles of submicroscopic microvilli. These bundles are also called stereocilia.

Top, left: In the centre of the lumen of the duct, the basophilic small nuclei of spermatozoa (Z) are clearly seen.

Bottom, left: The epithelium of the duct is cut tangentially or obliquely and part of the section traverses the layer of nuclei (arrows).

The epithelium of the duct is sitting on a connective tissue layer or lamina propria (LP).

The framed area is magnified 800 times in Figure 1.5.

Stain: H–E
Magnification: ×300
