What is the function of the extraembryonic mesoderm?
What is the function of the extraembryonic mesoderm?
- To form the endometrial stroma

What is the size of the bilaminar disc during day 11-12 of development?
- 0.5 to 1 mm
- 0.1 to 0.2 mm (correct)
- 0.6 to 0.7 mm
- 0.3 to 0.4 mm
What is the decidua reaction?
What is the decidua reaction?
- Establishment of the uteroplacental circulation
- Formation of the cytotrophoblast and hypoblast
- Changes in the endometrium, with cells becoming pale and loaded with glycogen and lipids (correct)
- Development of the lacuna at the embryonic pole

Study Notes
- Development on day 11-12 involves the formation of the cytotrophoblast and hypoblast lining the exocoelomic cavity.
- The blastocyst is embedded in the endometrial stroma.
- Lacuna are more developed at the embryonic pole.
- Uteroplacental circulation is established, allowing maternal blood to flow through the trophoblastic system.
- Extraembryonic mesoderm appears, forming fine loose connective tissue between trophoblast and amnion.
- The extraembryonic coelom or chorionic cavity is formed within this tissue.
- Growth of the bilaminar disc is relatively slow.
- The disc remains very small (0.1 to 0.2 mm).
- Decidua reaction begins as cells of the endometrium become pale and loaded with glycogen and lipids.
- Intercellular spaces also appear during the decidua reaction.
