Plate 5

Two normal 12-day ova also in Horizon Vc, characterized by intereommunicating lacunar spaces with evidence of early utero-placental circulation, a distended chorionic cavity, an exocoelomie cavity of maximum size, a bilaminar germ disc and a well-defined amnion and amniotic cavity. Details of their germ discs are shown on plate 6.

30 A medium-power view of a mid-cross section of the ovum shown in figure 31. A coagulum is lying over the uuhealed penetration defect as evidence of seepage of maternal blood and plasma from laennar space into the uterine lumen. Note the persistent edema of the endometrium and the early decidua developing immediately around the ovum. Note primordial villi and also the gland on the left which has been surrounded by syncytimn. A dilated blood vessel is seen at the margin of the ovum at the right. Carnegie 8558, Section 10-1-4. X 100.

31 A surface view of an intact 12-day implantation site to show the endonietrial detect, the source of maternal bleeding into the uterine lumen at. this and slightly later stages. Note the small tabs of coagalum in the ulcer. A hemorrhage, which became detached and hence is not shown, arose from this defect. Carnegie 8558, Sequence 5. X22.

32 A medium-power view of a mid-cross section of the ovum shown in figure 33. Note the early deeidual reaction about the ovum, the primordiuni of a villus on the left, the few blood cells within the lacnnar spaces and the large exocoelomic cavity. Carnegie 8330, Section 9-2-6. X 100.

33 A profile View of a 12-day ovum to show its elevation from the surrounding endometrium. Carnegie 8330, Sequence 3. X 12.
