HEY DEAR....!!
TROPHECTODM : Outermost layer of cells in the mammalian blastodermic vesicle, which will make contact with the endometrium and take part in establishing the embryo's means of receiving nutrition; the cell layer from which the trophoblast differentiates.
ECTODERM : ectoderm (ExE) is formed following implantation as cells from the polar trophectoderm proliferate. The process involves thickening of the polar trophectoderm, which grows into a thick compact column of extraembryonic ectoderm that extends into the blastocoel, with its distal part juxtaposed with the compact epiblast. Both the ExE and the epiblast are enveloped by the visceral endoderm.
