Human Embryo Stage 7

Appearance of section through implanted conceptus appears to be about a Carnegie stage 7 embryo.

Photo author states similar to the Hertig-Rock embryo (1945) dated as 16.5 to 19 days post-ovulation, or GA Week 4 to 5 week.

Carnegie stage 7

Features: embryonic disc, primitive node, primative streak, primitive groove, yolk sac
Facts: Week 3, 15 - 17 days, 0.4 mm
View: embryonic disc and chorionic vesicle.
Events: Gastrulation is continuing as cells migrate from the epiblast, continuing to form mesoderm.

-Facts: Week 3, 15 - 17 days, 0.4 mm
-View 1: embryonic disc, showing the epiblast viewed from the amniotic (dorsal) side.
-Events: Gastrulation is continuing as cells migrate from the epiblast, continuing to form mesoderm.
-Mesoderm lies between the ectoderm and endoderm as a continuous sheet except at the buccopharyngeal and cloacal membranes. These membranes have ectoderm and endoderm only and will lie at the rostral (head) and caudal (tail) of the gastrointestinal tract.
