Chorioallantoic Membrane Vasculature

  • Domenico Ribatti


Chick embryo development lasts 21 days before hatching. There are four extraembryonic membranes of the chick: the yolk sac, the amnion, the serosa, and the allantois. The serosa of the chick is occasionally called chorion; the term chorion, however, is more frequently applied to the composite layer formed by the fusion of the allantois and the serosa.
