These are not branches but are actually a direct continuation of the umbilical artery.

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

A placenta is an organ attached to the uterine wall with access to the mothers blood supply. Called also exomphalos and exumbilication. Inside the cord is one vein which contains oxygenated blood and two arteries.
