Light micrograph of normal human epididymis,the function of which is to accumulate and store sperm. The bulk of the epididymis consists of a coiled duct seen here in transverse section. The lumens of the ducts contain masses of spermatozoa (brown). The epithelium itself (purple) consists of a layer of columnar cells with elongated nuclei overlying a layer of rounded basal cells. The stratified dark blue layers between adjacent sections of duct are circularly arranged smooth muscle. Magnification: x20 at 6x6cm size | |
