OK, here's a weird question:

Why are navels different from any other scar?

If you have surgery or an accident that cuts your flesh, you (hopefully)
eventually heal, and what you have is scar tissue. Yet the navel, the
remains of the cutting of the umbilical cord, is not just a simple scar
on your abdomen, but seemingly a complicated structure, more sensitive
than the surrounding skin. Why is that? What is inside behind the navel?
(A lot of large blood vessels ending abruptly? Or do the blood paths
that existed to feed the placenta wither away and vanish after birth?)
