The yolk sac is a membranous sac attached to an embryo, formed by cells of the hypoblast layer of the bilaminar embryonic disc.This is alternatively called the umbilical vesicle by the Terminologia Embryologica (TE), though yolk sac is far more widely used.
The piping can be used during interventions.They encapsulate multiple coiled tubing and electrical strings into a single string which can be deployed by one conventional unit.
One of the earliest and most critical tasks in a submarine pipeline planning exercise is the route selection. [5] This selection has to consider a variety of issues, some of a political nature, but most others dealing with geohazards, physical factors along the prospective route, and other uses of the seabed in the area considered.
The amnion is avascular, meaning it does not contain its own blood vessels. Therefore, it must obtain necessary nutrients and oxygen from nearby chorionic and amniotic fluid, and fetal surface vessels. [7] [8] The amnion is characterised by cuboidal and columnar epithelial layers. [7]
Umbilical vessels can refer to: Umbilical artery , one of a pair of blood vessels that supply deoxygenated blood from within the fetus to the placenta Umbilical vein , a blood vessel that carries oxygenated blood from the placenta into the fetus
In the human embryo, the vitelline duct, also known as the vitellointestinal duct, [1] the yolk stalk, [1] the omphaloenteric duct, [1] or the omphalomesenteric duct, [1] is a long narrow tube that joins the yolk sac to the midgut lumen of the developing fetus. [2]
