How does a fetus not get tangled in the umbilical cord?

A substance called Wharton’s jelly provides cushioning around the important blood vessels of the cord and protects them even if the cord gets knotted. This means that the odds are in your favor (and your baby’s) that a true tight knot won’t occur.

What happens to the umbilical cord during pregnancy?

Now to your question, what happens to the cord? It is expelled from the mother within a half-hour after birth. It is still attached to the placenta, which is commonly called “the afterbirth.” With its function completed, it is no longer needed and so is discarded by the mother’s body.

What causes an umbilical cord to knot?

How do Umbilical Cord Knots Occur? During pregnancy, a developing baby kicks and turns in his or her mother’s belly. Over time, these fetal movements can lead to knots in the cord. Since fetuses move naturally throughout the woman’s womb in pregnancy, it’s natural that these knots might occur.

How do I know if my baby’s umbilical cord is tangled?

Signs The Umbilical Cord Is Around Baby’s Neck

• It’s visible via ultrasound.
• Baby is suddenly moving less in the last weeks of your pregnancy.
• Baby suddenly moves forcefully, then moves considerably less.
• Baby’s heart rate is decelerating during labor.

Can you see knot in umbilical cord on ultrasound?

On an ultrasound, any bulge or protuberance in the baby’s umbilical cord is likely to be a false knot. These “knots” are actually slight variations in the cord’s anatomy, usually formed by swollen blood vessels or an excessive covering of Wharton’s jelly. Small pseudoknots are relatively common in pregnancies.

Can a true knot be seen on ultrasound?

A true knot significantly increases the likelihood of fetal death and brain injury from hypoxic-ischemic encephalopathy (HIE). Knots are detectable via ultrasound, and it is standard of care to test for knots prenatally when certain risk factors exist.
