Light micrograph of normal human epididymis. The bulk of the epididymis consists of a coiled duct seen here in oblique (right) and transverse (left) section. The lumen of the duct contains masses of spermatozoa (red). The clear space around these is crossed by sterocilia from the epithelial lining of the duct wall; these are in places seen as fine blue lines. The epithelium itself 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: x50 at 35mm size | |
