Summary
Persistent right umbilical vein (PRUV) is a common venous anomaly. This study suggests a new type of PRUV where the right umbilical vein drains into the left liver, not just the right.
Area of Science:
- Embryology
- Vascular Anatomy
- Congenital Anomalies
Background:
- Persistent right umbilical vein (PRUV) is a recognized anomaly in human venous development.
- Previous assumptions suggested PRUV prevalence increases with earlier embryonic development.
Observation:
- Examination of 58 human embryos/fetuses (5-7 weeks gestation) revealed only two potential PRUV candidates.
- One specimen showed a degenerating right umbilical vein (UV) merging with a dominant left UV.
- Another specimen displayed a degenerating left UV joining a prominent right UV near the liver.
Findings:
- In both observed cases, the umbilical vein system ultimately drained into the left liver.
- This suggests a potential variant of PRUV where the right UV connects to the left liver, distinct from the typical right-sided drainage.
Implications:
- These findings challenge existing understanding of PRUV development and drainage patterns.
- Identifies a previously unrecognized anatomical variation in the fetal venous system.
- May necessitate revised diagnostic criteria and imaging protocols for fetal venous anomalies.

01:15Development of the Sexual Organs in the Embryo and Fetus
3.7K
Development of the reproductive organs in an embryo starts from a bipotential state. This means the early embryo can develop either male or female reproductive organs. The formation of these organs begins with the growth of gonadal ridges that arise from the intermediate mesoderm during the fifth week of development.
Near the gonadal ridges, two duct systems are present: the mesonephric ducts (Wolffian ducts) and paramesonephric ducts (Müllerian ducts). These ducts form the basis for the...

01:03Serial Position Effect
542
The serial position effect is a cognitive phenomenon where individuals are more likely to recall the first and last items in a list compared to those in the middle. This effect is divided into the primacy effect and the recency effect. The primacy effect is observed when the initial items in a list are remembered better. This occurs because these items are rehearsed more frequently or receive more elaborative processing, allowing them to be encoded into long-term memory more effectively. For...

In cross-sectional research, a researcher compares multiple segments of the population at the same time. If they were interested in people's dietary habits, the researcher might directly compare different groups of people by age. Instead of following a group of people for 20 years to see how their dietary habits changed from decade to decade, the researcher would study a group of 20-year-old individuals and compare them to a group of 30-year-old individuals and a group of 40-year-old...

Varicose veins, or varicosities, develop when the valves in the veins, which control blood flow, weaken or damage. It causes blood to pool and the veins to enlarge. Understanding the clinical manifestations, diagnostic approaches, and management options for varicose veins is crucial for effective treatment and relief.Clinical manifestationsClinical manifestations of varicose veins include a heavy, achy feeling or pain after prolonged standing or sitting. This discomfort can often be relieved by...

Veins are an integral part of our circulatory system, serving as the blood vessels that transport blood from all body regions to the heart. They are a network of hollow tubes that carry blood low in oxygen from the body's cells back to the heart for reoxygenation. Veins are crucial for maintaining the body's overall fluid balance and the continuous circulation of blood.

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
