Umbilical Cord Anatomy

The umbilical cord derives from the primitive umbilical ring which includes the connecting stalk yolk stalk vitelline vessels and a canal between the intraembryonic and extraembryonic cavities. Within the first week of life the remnant umbilical cord stump separates from the neonate creating the umbilicus commonly referred to as the navel.

The Umbilical Cord Which Connects Your Baby To The Placenta

At birth the umbilical cord which provided vascular flow between the fetus and placenta is clamped and cut.

Umbilical cord anatomy. A placenta is an organ attached to the uterine wall with access to the mothers blood supply. The cord contains one vein and two arteries housed within its protective whartons jelly. This is the distal part of the umbilical artery.

The persistent proximal. Sources of stem cells in the umbilical cord cells in surrounding cells in cord tissue blood from umbilical vein cells in perivascular regions surrounding umbilical vessels. Inside the cord is one vein which contains oxygenated blood and two arteries.

A number of abnormalities can affect the umbilical cord which can cause problems that affect both mother and child. The umbilical vein goes all the way to the fetuss liver where it splits into two. In the adult there are two vessels which the umbilical artery gives rise to.

The cord is covered by a simple epithelium of amniotic derivation which becomes stratified in late gestation. It is the lifeline of the fetus in the uterus throughout pregnancy. Plate 13261 umbilical cord.

These are not branches but are actually a direct continuation of the umbilical artery. Umbilical cord compression can result from for example entanglement of the cord a knot in the cord or a nuchal cord which is the wrapping of the umbilical cord around the fetal. The umbilical cord is a tube like structure that connects a fetus to the mothers placenta.

The umbilical cord uc is the essential life sustaining connection between fetus and placenta. It constitutes a stable connection to the fetomaternal interface while allowing fetal mobility that is essential for fetal development in general and neuromotor development in particular. The umbilical arteries are atypical of those of the remainder of the body in that they carry oxygen poor blood lack an internal elastic lamina and have considerable metachromatic ground substance within their.

The anatomy of the umbilical cord the umbilical cord contains valuable stem cells in the blood tissue and perivascular regions 1 figure 1. The umbilical cord is made up of a substance called whartons jelly instead of normal connective tissue and skin. Called also exomphalos and exumbilication.
