Fig. 12. A mid-cross section of a 12.5-day ovum
The amniotic cavity is a cleft-like space above the primitive ectoderm of the germ-disk. It is barely enclosed above by the amniogenic cells which are still arising, in places, from adjacent trophoblast: Details of this process, at higher magnification, are shown in figs. 14 and 15. The exocoelomic (Heuser’s) membrane has reached the high point of its development and is destined to disintegrate within the next few days. Its essential mesoblastic nature is shown by the character of its cells and by their attachment. in places, to the trophoblast from which they arose. Carnegie 7700, section 6-1-S, x 100.
