Gastrulation | Formation of Germ Layers | Ectoderm, Mesoderm and Endoderm

The video tutorial explains the embryological process of gastrulation, where a bilaminar disc transforms into a trilaminar disc, forming three germ layers: ectoderm, mesoderm, and endoderm. The ectoderm develops into the skin and nervous system, the mesoderm into musculoskeletal and cardiovascular systems, and the endoderm into internal organs. The video also covers the development of the blastocyst, its implantation into the uterus, and the formation of the placenta. The process of gastrulation, including the formation of the primitive streak and differentiation of cells, is detailed.
