Human Embryo Stage 7 Information

Carnegie stage 7

Features: embryonic disc, primitive node, primative streak, primitive groove, yolk sac

Facts: Week 3, 15 - 17 days, 0.4 mm

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.

Reference

Original Author Legend - Primitive Trilaminar Human Embryo in Tubal Pregnancy (40X)

"I think this is at about the same developmental stage as the Hertig-Rock embryo of 1945, which has been variously estimated at 16.5 or 19 days postovulation (4 to 5 weeks by conventional obstetrical dating, counting from the first day of the last menstrual period)."
