The umbilical cord contains Wharton's jelly, a gelatinous substance made largely from mucopolysaccharides that protects the blood vessels inside. It contains one vein, which carries oxygenated, nutrient-rich blood to the fetus, and two arteries that carry deoxygenated, nutrient-depleted blood away. [6]

The umbilical cord is a helical and tubular blood conduit connecting the foetus to the placenta. The umbilical cord achieves its final form by the 12th week of gestation and normally contains two arteries and a single vein, all embedded in Wharton's jelly.

2024年10月4日 · The umbilical cord is a flexible, coiled structure that provides oxygen and nutrients to a fetus during pregnancy. It connects to the placenta. After birth, your baby no longer needs the cord, so providers cut it (this is painless for you and your baby).

The umbilical cord is a fascinating structure that plays a crucial role in fetal development. It’s not just a simple tube; it acts as a lifeline, ensuring that the developing fetus receives essential nutrients and oxygen from the mother while also removing waste products.

The umbilical cord plays a crucial role as a structural unit within the fetoplacental complex, functioning autonomously with unique structural and functional characteristics [1, 17-19].

2018年2月13日 · Umbilical cord or the thread of life is not just a tube or a pipe; it is a unique organ with complicated architectures and sophisticated structures which enabled it to perform its vital function to supply the fetus with his requirement during the period of pregnancy.

2023年10月30日 · During embryonic development, the umbilical cord acts as a conduit between mother and baby and creates a channel which allows blood to flow between the placenta and fetus. After birth, the umbilical cord detaches and a fibrous scar, the umbilicus, remains.

2023年7月24日 · The umbilical cord is a bundle of blood vessels that develops during the early stages of embryological development. It is enclosed inside a tubular sheath of amnion and consists of two paired umbilical arteries and one umbilical vein.

Structure of the Umbilical Cord. The umbilical cord typically measures about 50 to 60 centimeters (20 to 24 inches) in length and has a diameter of about 1 to 2 centimeters. It consists of three blood vessels: two arteries and one vein.

In this article, we will explore the anatomy of the umbilical cord, its functions, and the potential complications that can arise during pregnancy. The umbilical cord is formed during the early stages of pregnancy, around the fifth week of gestation.

2022年7月31日 · The umbilical cord is a fetal organ that connects the placenta to the developing fetus and is a vital passage for nutrients, oxygen and waste products to and from the fetus. Gross anatomy. The umbilical cord inserts into the center of the placental bulk and into the fetus at the umbilicus. Variations in insertion can occur.

The structure of the umbilical cord receives only a cursory glance during many obstetric ultrasound examinations: with imaging limited to documenting the number of vessels within the cord and the insertion sites at the foetus and placenta.

2023年7月24日 · The umbilical cord is a bundle of blood vessels that develops during the early stages of embryological development. It is enclosed inside a tubular sheath of amnion and consists of two paired umbilical arteries and one umbilical vein.

1) The amnio-ectodermal junction is the primitive umbilical ring. 2) Following structures pass through the ring at the 5th week of development: a. Connecting stalk, containing Allantois and the umbilical vessels. b. Yolk stalk (vitelline duct), accompanied by vitelline vessels. c. Canal connecting the intraembryonic and extraembryonic cavities.

2023年11月21日 · The anatomy of the umbilical cord consists of two arteries, which leave the fetus and are directed towards the placenta. In addition, the umbilical cord contains a vein that runs from the placenta to the fetus. Both the arteries and the umbilical vein are in a gel-like tissue, providing strength to the cord and preventing the formation of knots.

2024年3月8日 · The placenta is an organ that forms in the womb, also called the uterus, during pregnancy. The placenta is connected to a developing baby by a tubelike structure called the umbilical cord. Through the umbilical cord, the placenta provides oxygen and nutrients to a developing baby. It also removes waste from the baby's blood.
