Plate 10. Chorionic Villi sections

Fig. 13. Section of the Villi and Edge of the Chorion. Photograph. x 140 d.


The section demonstrates that the villi are covered l>y a double- layered epithelium (cellular layer and plasiuodial layer).


Fig. 14. Section of a Single Villus and Mass of Lanohans' Layer Cells, more higlily magnified than in the last figure. Photogmph. x 240 d.


The two-layered epithelium covering the mesoblastic core of the villus is well seen. The mass of Langhans' layer cells is covered by a very distinct plasmodial layer (syncytium of authors).
