Exempel på hur man kan använda CHORION i en mening

• Conjoined twins share a single common chorion, placenta, and amniotic sac in utero, but so do some monozygotic but non-conjoined twins.
• The chorion is the outermost fetal membrane around the embryo in mammals, birds and reptiles (amniotes).
• The fact that an embryo in both placental mammals and marsupials undergoes the process of implantation, and forms the chorion with its chorionic villi, and later the placenta and umbilical cord, is also a difference from lower chordates.
• The trophoblast gives rise to the chorion and amnion, the two fetal membranes that surround the embryo.
• The embryos survive the dry season by entering diapause, facilitated by their specialized eggs that have a very hard chorion and are resistant to desiccation and hypoxia.
• The allantois, along with the amnion, chorion, and yolk sac (other extraembryonic membranes), identify humans and other mammals, birds, and reptiles as amniotes.
• It has also been found that trophic eggs in ants have a less pronounced reticulate pattern on the chorion.
• In the female, relaxin is produced by the corpus luteum of the ovary, the breast and, during pregnancy, also by the placenta, chorion, and decidua.
• In hemochorial placentation maternal blood comes in direct contact with the fetal chorion, which it does not in the other two types.
• Chorioamnionitis, also known as amnionitis and intra-amniotic infection (IAI), is inflammation of the fetal membranes (amnion and chorion), usually due to bacterial infection.
• The chorion undergoes rapid proliferation and forms numerous processes, the chorionic villi, which invade and destroy the uterine decidua and at the same time absorb from it nutritive materials for the growth of the embryo.
• The dorsal aortae give branches to the yolk-sac, and are continued backward through the body-stalk as the umbilical arteries to the villi of the chorion.
• They develop from undifferentiated hemangioblasts in blood vessels in the walls of the umbilical vesicle, allantois and chorion.
• The combination of ectoderm and mesoderm, or somatopleure, forms the amnion, the chorion and the lateral body wall of the embryo.
• With an increase in osmoregulation, the survival of naiads starts to decrease since this stage of the life cycle no longer has a chorion or the ability to osmoregulate.
• The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo.
• In developmental biology, choriogenesis is the formation of the chorion, an outer membrane of the placenta that eventually forms chorionic villi that allow the transfer of blood and nutrients from mother to fetus.
• In velamentous cord insertion, the vessels of the umbilical cord are improperly inserted in the chorioamniotic membrane, and hence the vessels traverse between the amnion and the chorion towards the placenta.
• In rounds 3 through 15, Mishra spelled "demitasse", "quadrat", "diener", "hyssop", "macédoine", "basenji", "numnah", "chorion", "nacarat", "sinicize", "hyphaeresis", "taleggio" and "esclandre" correctly, in that order.
• However, it can be inferred that dinosaur eggs had an amnion, chorion, and an allantois, the three major membranes in modern bird and reptile eggs.
