Fig.11. Section 99

General sectional view of the chorionic vesicle and the surrounding decidua.

The section (99) passes through the embryonal primordium at the level of the hinder end of the primitive streak and shows the amnio-embryonal vesicle, here much reduced in size, the very much larger yolk-sac vesicle and especially the connecting stalk attached to the chorion below the central region of the decidua capsularis.

ar. arteriole in d. marginalis. b.tr. basal trophoblast. c.s. connecting stalk. cv., cv.¹ veins in d. capsularis (d.c.). d.c.¹ portion of capsularis artificially separated. d.b. decidua basalis. d.m. d. marginalis. exoc. exocoelom. gi.uterine gland. gr. groove in decidua.mv., mv.¹ veins in d.marginalis. sy.tr. syncytio-trophoblast. x16.
