Primary ectoderm during gastrulation develops from _________ .
- A syncytiotrophoblast
- B cytotrophoblast
- C hypoblasts
- D epiblasts
Answer & Solution
Correct Answer
(D) epiblasts
Step-by-step Solution
Detailed explanation
Endoderm grows within the blastocoel and forms a sac called Yolk sac. The remaining cell of the inner cell mass, in contact with cells of Rauber are called epiblasts (primary ectoderm).
