5. Preimplantation

  • Describing the development of the embryo from the first cells to the blastocyst
  • Knowing the important stages of the preimplantation phase
  • Describing the importance of these stages
  • Knowing the duration of the preimplantation phase
Prerequisites

7. Embryonic disk

By the end of this module you should know about:

  • The differentiation of the embryonic germ layers, emanating from the trilaminar embryo
  • The mechanism of gastrulation and especially the morphogenetic role of the primitive streak
  • The arrangement of the intraembryonic mesoblast, its segmentation and the formation of the intraembryonic coelomic cavity

Prerequisites
  • Placenta
  • Implantation

8. Embryonic phase

At the end of this module you should know:

  • The differentiations of the germinal layers during the fourth week of development that lead to an individualization of the embryo.
  • The key concepts of the embryonic period that describe the first stages of organogenesis.
  • The various types of congenital abnormalities and be able to cite a few characteristic examples.
Prerequisites
