प्रश्न
Answer the following question.
Name the embryonic stage that gets implanted in human females. Explain the process of implantation.
उत्तर
A blastocyst is an embryonic stage that gets implanted in the uterus of the female.
Implantation involves the attachment of the blastocysts to the uterine epithelium. The process of implantation begins at the end of week 1, it requires the newly hatched blastocyst loosely adhered to the endometrial epithelium layer within the uterus.
The blastocyst is arranged into an outer layer called the trophoblast and an inner cell mass. It is the trophoblast cells that proliferate rapidly and differentiate into an inner layer of cytotrophoblast and an outer multinucleated cell layer, the syncytiotrophoblast
The projections of cytotrophoblast and syncytiotrophoblast bring the embryo into the endometrium so that it will fully be covered by endometrium epithelium.
