Exempel på hur man kan använda AMNION i en mening

• The fluid within the amnion is called amniotic fluid, and because this fluid surrounds the developing fetus, it contains fetal cells.
• The inner of these membranes, the amnion, encloses the amniotic cavity, containing the amniotic fluid and the embryo.
• The amnion (: amnions or amnia) is a membrane that closely covers human and various other embryos when they first form.
• The most common caul type is a piece of the thin translucent inner lining of the amnion that breaks away and forms tightly against the head during birth.
• The trophoblast gives rise to the chorion and amnion, the two fetal membranes that surround the embryo.
• However, without the gestational conditions in utero with the amnion and placenta, a fetus in fetu can develop into, at best, an especially well differentiated teratoma; or, at worst, a high-grade metastatic teratocarcinoma.
• The allantois, along with the amnion, chorion, and yolk sac (other extraembryonic membranes), identify humans and other mammals, birds, and reptiles as amniotes.
• 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 combination of ectoderm and mesoderm, or somatopleure, forms the amnion, the chorion and the lateral body wall of the embryo.
• The chorion, together with the amnion, forms the amniotic sac and encloses the amnion, vitellus, and the embryo.
• 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.
• 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.
• The cells of the inner cell mass (embryoblast), which are known as human embryonic stem cells (hESCs), will further differentiate to form four structures: the amnion, the yolk sac, the allantois, and the embryo itself.
• The name "anamniote" is a back-formation word created by adding the prefix an- to the word amniote, which in turn refers to the amnion, an extraembryonic membrane present during the amniotes' embryonic development which serves as a biochemical barrier that shields the embryo from environmental fluctuations by regulating the oxygen, carbon dioxide and metabolic waste exchanges and secreting a cushioning fluid.
• The amnion and the chorion are the chorioamniotic membranes that make up the amniotic sac which surrounds and protects the embryo.
• Circumvallate placenta is a rare condition affecting about 1-2% of pregnancies, in which the amnion and chorion fetal membranes essentially "double back" on the fetal side around the edges of the placenta.
• Progressive expansion of the amnion from the umbilical ring (surrounding the roots of the vitelline duct and connecting stalk) creates a tube with a covering of amniotic membrane with allantois and umbilical vessels as its content and mesoderm of the connecting stalk as the ground substance.
• There are four standard extraembryonic membranes in reptiles and mammals: the yolk sac which surrounds the yolk, the amnion which surrounds and cushions the embryo, the allantois which among avians stores embryonic waste and assists with the exchange of carbon dioxide with oxygen as well as the resorption of calcium from the shell, and the chorion which surrounds all of these and in avians successively merges with the allantois in the later stages of egg development to form a combined respiratory and excretory organ called the chorioallantois.
• Similar formations have also been found in sea-cow, lemur and hippopotamus, but the objects found in the amnion and allantois are distinguishable.
