Description

This detailed 3D model illustrates the second week of human development. It shows bilaminar disc formation, showing the epiblast and hypoblast layers, as well as the developing amniotic and yolk sac cavities. The model highlights implantation into the uterine lining and the early establishment of maternal-fetal interactions. By focusing on structural differentiation, it provides learners with a clear understanding of how the groundwork is laid for gastrulation and future tissue development.
