The fetal membranes consist of the chorion, amnion, yolk sac, and allantois. The chorion has three layers: cytotrophoblastic, chorionic connective tissue, and basement membrane. The chorion lies ...
After the first few weeks of growth, this thick path to and from the placenta has blood vessels, a channel (that will later become the intestine), and a tube called the allantois. The inside of the ...

Further similarity was found in the covering of the organ. There are four extra-embryonic membranes that are part of the placenta, including the yolk sac, amnion, allantois, and chorion. For the brain ...
12 13 Approximately half of the null mutants die before E11.5 and exhibit a failure of the allantois to fuse with the chorion. The remaining VCAM-1 null mutants appear to form a normal connection ...
