The different tubules,however, exhibit great vari-ation in the exact stageof these changes, adjacentcanals, and, in fact, parts ofthe same one, often present-ing the extremes of thecycle side by side. Next the basement-membrane of the seminiferous tubule lies a layer of low cuboidalnucleated parietal cells; this peripheral zone contains cells oftw
