Study Notes

  1. Development on day 11 and 12 involves slow growth of the bilaminar disc.
  2. Decidua reaction begins, causing endometrial cells to become glycogen and lipid-loaded.
  3. Trophoblast primary villi appear on day 13.
  4. The endometrial defect at the site of implantation heals completely.
  5. Secondary yolk sac appears within the exocoelomic cavity.
  6. Chorionic cavity and chorionic plate appear.
  7. Buccopharyngeal membrane appears as a thickening of the hypoblastic disc.
  8. The bilaminar disc remains small (0.1 to 0.2 mm).
  9. Cells of the cytotrophoblast proliferate locally and penetrate into the syncytiotrophoblast.
  10. Intercellular spaces in the endometrium become filled with extravasate and the tissue is edematous.
