The development of the umbilical cord begins in the third week of embryologic formation. The developing embryo consists of a trilaminar disc attached to the decidua basalis by the connecting stalk, the primitive umbilical cord.[1] [2] The connecting stalk is a thick stalk of the extraembryonic membrane extending from the caudal end of the embryo to the center of the developing placenta on the decidua basalis.[3] The process of body folding occurs during week four with rapid growth amnion and embryonic disc compared to the yolk sac. Cranial caud ...

Anatomical Features of an Umbilical Cord · The umbilical cord is a soft, tortuous cord with a smooth outer covering of amnion. It extends from the umbilicus of the fetus to the center of the placenta. Its length ranges from 50 cm to 60 cm, with a diameter of about 1 cm.[6] The umbilical cord is composed of a gelatinous ground substance called Wharton's jelly or substantia gelatinea funiculi umbilicalis. It is composed of mucopolysaccharides from the conjugation of hyaluronic acid and chondroitin sulfate. As previously mentioned, three vessels ...
We all had one, but do we really appreciate all that it does and all that it can tell us. The umbilical cord is the connection between a fetus and its mother during pregnancy. There are two arteries and one vein that take oxygen and nutrition to the baby and remove the waste material from the baby. The blood vessels are surrounded by a gelatinous substance called Wharton’s Jelly for protection. False knots – a bulge in the surface of the cord, usually an accumulation of Wharton’s Jelly, not a risk factor ...
