Hypoblast forms:
Ans. D Prochordal plateRef: Netter's Clinical Anatomy, 3rd ed. pg. 39* Hypoblast and epiblast are 2 germ layers in the second week of embryonic development.* The hypoblast gives rise to prochordal plate which is the future site of mouth and forms the cranio-caudal axis.* Notochord is formed by epiblast cells.* Epiblast is also the source of all three germ layers.* First germ layer to be formed is the endoderm. Q* Remnants of notochord are nucleus pulposus and apical ligament of atlas.
