WebThe chorionic plate of the placenta is formed by the proliferation of cytotrophoblasts and degeneration with deposition of fibrin-type fibrinoid. Fetal allantoic vessels fuse with this layer and begin to connect with vessels formed independently within villi. In extraplacental sites, the chorion apposes the maternal capsular decidua. WebSep 17, 2024 · This layer proliferates rapidly and forms numerous processes, the chorionic villi (the chorion is the layer that surrounds the embryo and extraembryonic membranes).
