Fig. 617. Transverse section of the ovary of a human embryo of 50 mm head-foot length

(Embryo R. Meyer 272; slide 2, row 1, section 2, from the collection of Professor R. Meyer, Berlin.) X ca. 75.

The section shows the triple division of the mesonephric fold into a tubal portion with the Müllerian duct, a gland portion with the primary excretory duct and mesonephric tubules and, finally, a very thin mesentery portion. In the ovary the superficial epithelium is distinctly separated from the epithelial nucleus. The nucleus is indistinctly dividing into a medullary layer, with numerous genital cells, and a cortical layer, poor in genital cells. Numerous trabecular of young connective tissue occur in the epithelial nucleus. The rete blastema is partly in the mesovarium and contains genitaloid cells.
