Summary
A single umbilical artery is a condition where one of the two umbilical arteries is absent or atrophied. This variation in umbilical cord anatomy can occur during fetal development.
Area of Science:
- Embryology
- Fetal Development
- Vascular Anatomy
Background:
- The umbilical cord typically comprises one vein and two arteries.
- The umbilical vein transports oxygenated blood from the placenta to the fetus.
- The umbilical arteries return deoxygenated blood and waste products from the fetus to the placenta.
Observation:
- Occasionally, developmental anomalies lead to variations in umbilical cord structure.
- These anomalies include primary agenesis (failure to form) or secondary atrophy (degeneration) of an umbilical artery.
Findings:
- The absence or atrophy of one umbilical artery results in a single umbilical artery (SUA).
- SUA represents a deviation from the typical two-artery, one-vein structure.
Implications:
- Understanding SUA is crucial for prenatal diagnostics and monitoring.
- Further research may explore potential associations between SUA and fetal development outcomes.
- Accurate identification of SUA aids in appropriate clinical management and counseling.

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...

Once the aorta traverses the diaphragmatic plane at the aortic hiatus, it is known as the abdominal aorta. This anatomical structure is positioned leftward of the spinal column, encased within a cocoon of adipose tissue behind the peritoneal cavity. It terminates at the L4 vertebra, where it splits into the common iliac arteries. Prior to this bifurcation, the abdominal aorta gives rise to several vital branches.

The external iliac artery transitions out of the body cavity, entering the femoral region of the lower leg, and is renamed the femoral artery at the point where it traverses the body wall. This artery is responsible for the distribution of blood to the thigh's deep muscles and the skin's ventral and lateral regions, achieved through several minor branches and the lateral deep femoral artery, which also spawns a lateral circumflex artery. The knee area receives blood from the genicular...

The coronary arteries, originating from the ascending aorta, bifurcate from two sinuses located within the ascending aorta. Positioned just above the aortic semilunar valve, these sinuses house essential aortic baroreceptors and chemoreceptors, crucial for maintaining cardiac function. The left coronary artery and the right coronary artery branch off from the left posterior and anterior aortic sinuses, respectively.

01:07Development of Blood Vessels
2.0K
The development of the vascular system in a fetus is a complex and intricate process that begins as early as 15 to 16 days post-conception. This process starts outside the embryo, specifically in the mesoderm of the yolk sac, chorion, and connecting stalk. Approximately two days later, the formation of blood vessels occurs within the embryo itself.
The initial formation of this system is facilitated by the small amount of yolk present in the ovum and yolk sac. Blood vessels originate from...

The thoracic section of the aorta begins at the T5 vertebra and extends to the T12 level at the diaphragm, initially progressing through the mediastinum to the left of the spinal column. Throughout its course in the thoracic segment, the thoracic aorta emits various offshoots known collectively as visceral and parietal branches. The branches that predominantly supply blood to visceral organs are termed visceral branches and include bronchial, pericardial, esophageal, and mediastinal arteries,...
