The fetal membranes are the four extraembryonic membranes, associated with the developing embryo, and fetus in humans and other mammals. They are the amnion, chorion, allantois, and yolk sac.^[1] The amnion and the chorion are the chorioamniotic membranes that make up the amniotic sac which surrounds and protects the embryo.^[2] The fetal membranes are four of six accessory organs developed by the conceptus that are not part of the embryo itself, the other two are the placenta, and the umbilical cord.^[1]
