Question

Find out more about about cells of Rauber ​

Answer 1

Answer:

The trophoblast does not take part in the formation of the embryo proper. It remains external to the embryo and gives rise to the extraembryonic membranes, namely, chorion and amnion, for the protection and nourishment of the embryo. The trophoblast cells in contact with the embryonal knob are known as cells of Rauber.
