The exocoelomic cavity forms inside the extraembryonic mesoderm alongside the placental chorionic plate and is now believed to be an essential transfer interface and reservoir of nutrients for the embryo because coelomic fluid has shown to have ultrafiltrate of maternal serum as well as products derived from the placenta and secondary yolk sac. Before it disappears, the coelomic cavity acts as a transfer area as well as a reservoir of nutrients for the growing embryo. ![]() The coelomic fluid within the coelomic cavity stays in direct contact with the mesenchyme of the developing placenta villi during the first trimester. The formation of the coelomic cavity begins during the fourth week of gestation when the exocoelomic cavity splits the extraembryonic mesoderm into the splanchnic mesoderm lining and the somatic mesoderm. In early gestation, two fluid-filled sacs surround the embryo: the exocoelomic cavity and the amniotic cavity. During the embryonic period, amniotic fluid derives from both fetal and maternal factors such as water from maternal serum, coelomic fluid, and fluid from the amniotic cavity however, during late gestation, amniotic fluid is largely produced by fetal urine and lung secretions. The composition of amniotic fluid changes from early gestation to late gestation. Early gestation is the embryonic period which is from the start of fertilization to 8 weeks, and late gestation, which encompasses the fetal period 8 weeks to birth. Have fun, relax and enjoy your ultrasound sessions! After all, your baby is the boss when it comes to obtaining the perfect picture.The development of amniotic fluid organizes into early gestation and late gestation. Just remember there can be many factors affecting the quality of your ultrasound images. You may want lots of images of your baby’s face but if your baby is facing the wall (uterine wall), has hands or legs covering the face or is pushing up against the placenta, the face will be completely or partially covered therefore looking a little weird on 3D and 4D images.Īdequate amount of fluid surrounding your baby (amniotic fluid) will also provide a better quality image of your baby as there will be less absorption and scattering of the ultrasound waves thus creating a ‘window’ to see baby. It is easy to see the entire baby early on in pregnancy but difficult to obtain detailed facial feature and as your baby still has little body fat, there would not be much covering the bones. Timing of your ultrasound makes a difference. Unfortunately, on some surfaces, it is not possible to get an accurate read and your baby’s face can look strange. ![]() It is therefore very common for family members or friends taking the same journey to discuss tips and tricks for pregnancy and compare ultrasound images! You will at times ask yourself ‘Why are my images different ?’ Firstly, it depends if the image obtained is 2D, 3D or 4D.ĢD captures an image of your baby in one plane and 3D puts together many 2D images from different angles to form a three-dimensional image. These ultrasound images will be your pride and joy throughout your motherhood journey. This exciting time is when you can see your baby’s heartbeat, how it is growing as well as obtaining the many 3D images for your keepsake album. One of the many precious moments in pregnancy is going for an ultrasound. ![]()
