Introduction
FactsHuman embryonic stage 7 occurs during week 3 between 15 to 17 days. The embryo is now 0.4 mm diameter in size. The initial images are displayed unlabeled to allow you to explore the embryo for yourself, linked labeled versions are also available for some images. EventsGastrulation 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. From the primitive node a tube extends under the ectoderm in the opposite direction to the primitive streak. This tube forms first the axial process then notochordal process, then finally the notochord. The notochord is a key to embryonic folding and regulation of ectoderm and mesoderm differentiation. It lies in the rostrocordal axis and the embryonic disc will fold either side ventrally, pinching off a portion of the yolk sac to form the lining of the gastrointestinal tract.

View: embryonic disc, showing the epiblast viewed from the amniotic (dorsal) side. Head to tail orientation is Cranial (image top) and Caudal (image bottom).
Features: embryonic disc, primitive node, primative streak, primative groove, connecting stalk
Alternate View: embryonic disc, probably from from the ventral side. Showing the connecting stalk to the left.
