label [en]	extraembryonic reticulum
comment [en]	the network of interstitial tisssue composed of reticular  fibres  which is situated outside the embryo proper. A layer of cells called the extraembryonic reticulum is secreted between Heusers membrane and the cytotrophoblast. This eventually breaks down into fluid and forms the chorionic cavity. The origin of extraembryonic reticulum is still a controversial issue. In accordance with evidence from other species, it is widely accepted that endoderm delaminates from the embryonic disc, probably to form the hypoblast and migrates round the internal surface of the blastocystic cavity.
