WebIn humans, the chorion is simply the original trophoblast, which becomes lined by somatic mesoderm. The chorion is relatively avascular; blood perfusion is achieved instead by the allantoic vessels. But the chorion (vascularized by the allantois) is the essential component of chorionic villi. The chorion is the outermost fetal membrane around the embryo in mammals, birds and reptiles (amniotes). It develops from an outer fold on the surface of the yolk sac, which lies outside the zona pellucida (in mammals), known as the vitelline membrane in other animals. In insects it is developed by the … See more In humans and other mammals (excluding monotremes), the chorion is one of the fetal membranes that exist during pregnancy between the developing fetus and mother.

Comparative biological effects of human amnion and chorion …

The fetal membranes surround the developing embryo and form the fetal-maternal interface. The fetal membranes are derived from the trophoblast layer (outer layer of cells) of the implanting blastocyst. The trophoblast layer differentiates into amnion and the chorion, which then comprise the fetal membranes. The amnion is the innermost layer and, therefore, contacts the amniotic fluid, the fetus and the umbilical cord. The internal pressure of the amniotic fluid causes the amnion to … WebDec 20, 2024 · The fetal surface of the placenta (or chorionic plate) is covered by the amnion, or amniotic membrane, which gives this surface a shiny appearance.
