Are there nerves in the umbilical cord?

I'm talking about the human umbilical cord, specifically, and I'm curious whether newborns feel anything when it's cut.

No. The only structures in the umbilical cord are two arteries and a vein, unsurprisingly called the umbilical arteries and the umbilical vein. The cord's not even made of muscle or skin. It's composed, apart from those blood vessels, of a substance called Wharton's jelly, which is the same kind of stuff that fills your eyeballs.
