Estrogen is secreted by both the _____ and the _____. The primary male sex hormone _____. The thin walled side of the blastocyst forms the _____. The extra embryonic membrane associated with waste storage in chicken, but becomes part of the umbilical cord in humans is the _____. The involution (folding in) of cells results in the formation of the _____. In a human embryo, the morula becomes the _____.

Explanation / Answer

12. Human eggs are stored in Follicle ( Ovary contain fluid-like structures that present in ovary and helps in maturation of egg or oocytes)

13. Follicle stimulating hormone is produce by pituitary gland (Gonadotropic cells of anterior pituitary gland)

14. Leutinizing hormone is produced by pituitary gland (Gonadotropic cells of anterior pituitary gland)

15. Progesterone is produce by Adrenal gland ( it is also secreted by placenta during pregnancy time and by ovary)

16. Estrogen is secreted by Copus luteum and the follicles of ovary

17. Primary male sex hormone is Testosterone (ad)

18. The thin walled side of the blastocyte forms the Trophoblast (bc). (Syncytiotrophoblast is the outer most layer of trophoplast)

19. Trophoblast (bc)

20. The involution of cells results in the formation of Gastrulla (bcd)

21 . In a human embryo, morula becomes Blastula (abd)
