Das Chorion frondosum bildet sich während des 3. Schwangerschaftsmonats. In diesem Zeitraum bleiben nur die Chorionzotten der Basalplatte bestehen Chorion. The chorion is one of the embryonic membranous structures that enclose both the fetus as well as the amnion. The chorion begins to form chorionic villi towards its outer surface, which initially serves to provide nutrition to the developing embryo. Part of the chorionic villi arborize more extensively and forms the chorionic frondosum. fetal component: chorion frondosum is formed by an arterial plexus (branches of the umbilical artery), protruding into intervillous spaces as chorionic villi; Gross anatomy. Typically, the placenta is discoid in shape Chorion frondosum is tissue surrounding the developing embryo. It is fetal in origin and will eventually become the placental site. It can be biopsied by the technique of CVS first described in the late 1960s and now a routine procedure for prenatal diagnosis

Placental mammals, such as humans, have a chorioallantoic placenta that forms from the chorion and allantois. In humans, the placenta averages 22 cm (9 inch) in length and 2-2.5 cm (0.8-1 inch) in thickness, with the center being the thickest, and the edges being the thinnest. It typically weighs approximately 500 grams (just over 1 lb) On one side of it is chorion frondosum, with all the villi inside; Villi contain fetal blood between the villi is the intervillus space that houses maternal blood; lateral to the chorion frondosum, is decidua basalis; on the other side of the amniotic cavity, is the chorion laeve, with the decidua capsularis lateral to that. Vill Als het chorion groeit komt het gladde gedeelte in aanraking met de decidua parietalis en fuseert het met deze lagen. De villi bij de embryopool die in contact staan met de decidua basalis worden sterk vergroot en meer complex. Dit deel wordt het chorion frondosum genoemd.

  4. Chorion biopsy was performed in 165 cases at 6-12 weeks of pregnancy, following an ultrasonic or embryo-fetoscopic chorion frondosum localization. One hundred patients had their biopsies taken immediately before induced abortion. In 39 cases abortion was carried out 5-10 days after biopsy

chorion (plural chorions or choria) ( anatomy , biology ) The protective and nutritive membrane in higher vertebrates that attaches the fetus to the uterus . 2002 , Rovert E. A. Stewart, Barbara E. Stewart, Female Reproductive Systems , entry in Encyclopedia of Marine Mammals , page 425 The villi at the embryonic pole, which is in contact with the decidua basalis, increase greatly in size and complexity, and hence this part is named the chorion frondosum By 7 weeks, the embryo has grown to about 10mm long from head to bottom. This measurement is called the crown-rump length. The brain is growing rapidly and this results in the head growing faster than the rest of the body. The embryo has a large forehead, and the eyes and ears continue to develop. The inner ears start to develop, but the outer ears on the sides of the head will not appear for.

chorion frondosum - region of chorion with villi whose association with the decidua basalis is the essential unit of the placenta chorion laeve - abembryonic region of chorion that is without villi, therefore, smooth (laeve) chorionic gonadotropin (hCG) - hormone secreted by the trophoblast, resembles luteinizing hormon Chorion Definition. 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. During development, the embryo grows inside, and beside, four extraembryonic membranes that protect and nurture it chorion frondosum and decidua basalis In the early weeks of development, villi cover the entire surface of the chorion. As pregnancy advances, villi on the embryonic pole continue to grow and expand, giving rise to the chorion frondosum (bushy chorion) Decidua basalis (Decidual plate) Chorion frondosum Chorionic plate Chorion leave Dr. Sherif Fahmy 6.

Around 8 weeks' gestation, the villi oriented toward the endometrium (now called the decidua) continue to divide and grow as the chorion frondosum. The villi toward the endometrial cavity atrophy and form a smooth surface, the chorion laeve. The chorion normally apposes with the amnion at approximately 12 to 16 weeks

Il corion è la membrana più esterna dell'uovo fecondato, composta da due parti, che si distinguono tra loro nel corso del secondo mese di vita intrauterina: corion villoso, o frondoso (chorion frondosum), nel quale i villi coriali si allungano e si ramificano, corrispondente alla zona di inserzione dell'uovo che dà luogo alla placenta ed alla membrana coriale, situata tra l'amnios.

The outermost membrane of the placenta is In ruminants, chorion frondosum is organized as arborizing chorionic villi assembled into larger macroscopically visible tufts called cotyledons.

The chorion frondosum produces millions of villi that carry fetal capillaries so that the blood within them can come into close contact with maternal blood flowing through the intervillous spaces. Maternal and fetal blood do not mix in the placenta. The maternal blood flow into the placenta is through the decidua to bathe the chorionic villi. The chorion frondosum (literally bushy chorion) arises from the polar pole of the human embryo trophoblast. It consists of a layer of trophblasts and extraembryonic mesoderm surrounded by numerous villi. This portion of the placenta is located at the site of implantation Chorion, also called Serosa, in reptiles, birds, and mammals, the outermost membrane around the embryo.It develops from an outer fold on the surface of the yolk sac. In insects the chorion is the outer shell of the insect egg.. In vertebrates, the chorion is covered with ectoderm lined with mesoderm (both are germ layers) and is separated from other embryonic membranes by an extraembryonic. Chorion frondosum biopsy is a method of antenatal diagnosis based on the chorion villi cell analysis, with the aim of detecting hereditary disorders of chromosomal and genetic origin. The method was applied at the Department of Gynaecology and Obstetrics in women with undesired pregnancy from 8 to 12 weeks

The chorion surrounds the embryo and other membranes. It consists of two layers: an outer formed by the primitive ectoderm or trophoblast, and an inner by the somatic mesoderm; with this latter the amnion is in contact. and hence this part is named the chorion frondosum Covering the external face of the amnion and lining the inner face of the chorion is a double membrane, _the allantois_..
