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