Chorion - Wikipedia The chorion is the outermost fetal membrane around the embryo in mammals, birds and reptiles (amniotes) It is also present around the embryo of other animals, like insects and molluscs
Chorion: Anatomy and function | Kenhub The chorion is the outermost of the four membranes surrounding the developing fetus, consisting of trophoblast and underlying extraembryonic mesoderm It is continuous with the lining of the uterine wall (endometrium) superficially and is in contact with the amnion deep to it
Difference Between Amnion and Chorion The chorion, on the other hand, is the outer membrane that surrounds the amnion, the embryo, and other membranes and entities in the womb It is considered as the support platform of the fetus and the amnion
Amnion vs. Chorion - Whats the Difference? | This vs. That The chorion is the outermost layer of the fetal membranes and is derived from the embryonic trophoblast It surrounds the amnion and forms a protective barrier between the fetus and the maternal tissues
Chorion - Definition and Examples - Biology Online Dictionary The chorion is the outermost membrane that surrounds the developing embryo, while the amnion is a fluid-filled sac that surrounds the embryo and helps to protect it from mechanical shock and dehydration
Chorion in Embryology: A Comprehensive Guide The chorion is the outermost membrane surrounding the embryo, formed from the trophoblast and the extraembryonic mesoderm It develops from the cytotrophoblast and syncyotrophoblast layers of the trophoblast, which differentiate and proliferate to form the chorionic villi
Chorion - an overview | ScienceDirect Topics The X chromosome cluster below contains two major chorion genes, s36 and s38, as well as several genes that encode minor chorion proteins (A, B, C, and s37) The positions of the transcripts are shown by the lines with arrows
Chorion - Definition, Explanation Function | Biology Dictionary The chorion is one of the membranes that surround the fetus while it is still being formed In mammals, the fetus lies in the amniotic sac, which is formed by the chorion and the amnion and separates the embryo from the mother’s endometrium
Chorion | definition of chorion by Medical dictionary The multilayered, outermost fetal membrane consisting of extraembryonic somatic mesoderm, trophoblast, and, on the maternal surface, its villi are bathed by maternal blood; as pregnancy progresses, part of the villous chorion becomes the fetal part of placenta
