Close to the mediastinumthey taper into short, straight tubes (tubuli recti), of smaller diameter than the seminiferoustubes, and differingfrom them in thecharacter of their epi-thelium (fig. 596).This, in the straighttubules, is a singlelayer of flattened orcubical cells continu-ous with the outer or Fig.
