I have a deep belly button. A really deep belly button. It’s so deep that I’ve actually used it for storage on a number of occasions. As I was sitting around picking lint out of my cavern of a belly button last night (gross – I know), I started to wonder why my belly button was so deep. I also started wondering why some people have those adorable little outie belly buttons when I am stuck with a big gaping hole in my mid-section. Am I a genetic mutant, or did the doctor do a number on me when he was chopping off my umbilical cord?
In an effort to understand a part of my body that I really know nothing about, I thought I’d do a little internet research and put together a little grade-school report on the belly button. So here it is, for your enjoyment, my belly button report.
About The Belly Button
The belly button was invented in 1852 by an ambitious young man named Eli Whitney. Oh wait, that was the cotton gin – my bad! The belly button is actually the body’s first scar and it is due to the removal of the umbilical cord after birth. Typically after the placenta has been expelled, two clamps are placed on the umbilical cord several inches away from the baby and the cord is cut between the clamps. The umbilical cord that remains attached to the baby eventually withers and falls off, leaving a scar, which we call the belly button.
For some people, like me, this scar is concave and it recedes into the body, creating an “innie”. For others, the scar tissue pushes out from the body giving these people an “outie”. Most sources claim that 90% of people have innie belly buttons, which puts the outies in a small 10% minority.
Belly Button Myths
Myth #1: Outie Belly Buttons Are A Genetic Mutation
Some theorize that because there are so many innie’s, that outie belly buttons are a genetic mutation. This type of theorizing is often done to taunt those with the unique outie belly buttons. So far there is no scientific proof that the type of belly button you have is at all linked to genetics.
Myth #2: The Doctor Can Influence Innie vs. Outie
Another theory holds that the way the doctor handles the umbilical cord can influence whether the baby will have an innie or an outie. This doesn’t really hold water either though because the umbilical clamps are almost always placed several inches away from the baby – too far to effect the development of the scar tissue.
Myth #3: The Old Quarter Trick
There is an old wives tale that claims the magical powers of quarters over belly buttons. The story goes that if you tape a quarter over a baby’s outie belly button, it will eventually push itself in. I have absolutely no idea if this is true or not. There are many women who claim this to be true, but it certainly sounds like a stretch to me.
Myth #4: The Belly Button Hernia
Another idea about how outie belly buttons came to be is that they are a result of an abdominal hernia. In rare cases when an infant’s abdominal walls collapse due to weakness, called a hernia, the baby’s belly button could push out instead of becoming concave. Most doctors believe that the chances of this effecting the direction of the belly button long term are minimal though, so this myth might be busted too.
