Figure 4. Scanning electron microscopic images of the apocrine process in the 9.

The gland, dissected under the stereomicroscope and having a lumen evidently filled with material, was fixed and processed to critical point drying, after which it was broken up to expose inferior portion that included the luminal surface, and then sputter coated. The image reveals (a) numerous aposome-like spheres (arrows) and various material-bearing structures on the surface of apical membrane (10000×). In addition, at higher magnification (b), some of these spheroid structures (arrows) displayed constrictions and show a decapitation of the aposome's stalk (arrowheads) (20000×).
