Question

Which component of the placenta originates from the trophoblast of the blastocyst and is also called the chorion frondosum?

पर्याय

• Maternal placenta

• Foetal placenta

• Syncytiotrophoblast

• Decidua basalis

Answer 1

The foetal placenta originates from the trophoblast of the blastocyst and is also termed the chorion frondosum. It is composed of chorionic villi, embryonic connective tissue, and blood capillaries. This component forms the foetal side of the placental interface and is responsible for the extensive surface area needed for efficient maternal-foetal exchange.
