- Hysterectomy Posterior wall of uterus. “The primitive villi are short and stubby; a few reach a length of about 0.25 mm.” Chorion, 2.6 x 1.9 x 1.4 mm. Chorionic cavity, 1.3 x 1.1 x 0.8 mm. Embryonic disc, 0.04 x 0.22 x 0.253 mm. Primitive streak, 0.04 mm. “Axial differentiation is just appearing.” “In this embryo the site of the future [cloacal] membrane seems indicated, but not the structure itself.” Probably no allantoic duct. Presumed age, 13-13.5 days. Median projection published (ibid., plate 3).
