Fig. 652. The division of the ventral remains of the cloaca is completed

The vesico-urethral anlage and the pars pelvina of the sinus urogenitalis are narrowed in their dorso-ventral diameters, broadened in their frontal ones. The pars phallica remains broad in the sagittal diameter, but is narrowed in the frontal one, so that the lumen is abolished in the region of what will later be the glans; from the two walls an epithelial plate, the urethral plate, is formed. The lumen is retained, corresponding to the extent of the ostium urogenitale (not cut in the section figured).
