When I had my dd's I was really surprised that the umbilical cord looked all curly, a bit like a telephone cable when it is pulled.
I thought it would be straight. When I watched ER the other night a baby there was born and the cord was straight.
Do some people have straight umbilical cords? Am I weird or is ER unrealistic?
I can only really remember clearly my last baby's cord as it was quite unusual and the midwife commented on it. It was so thick that it looked almost straight but with slightly undulating look about it. The midwife's comment was "you obviously didn't smoke then?"
The cord has a big vein running through it with 2 arteries wrapped round it. It is covered in Wharton's jelly which can be quite thick. Depending on the size of the vein and arteries and the thickness of the jelly, the cord can look straight or it can look curly. Some even have knots in them.
What that means is that the placenta delivered itself inside out if you like. The side that was attached to the womb was on the outside - like a turned inside out umbrella. When it peels off the womb it often comes shiny side first (side next to baby) with the side that was attached to the womb on the inside.
