Do all humans have a belly button?
Your belly button marks the spot where your umbilical (say: um-BIL-ih-kul) cord was once attached. This cord is a soft, bendable tube that carried nutrients — vitamins and minerals — from your mother to you, back when you were in her belly (womb). A belly button is also called a navel.
Whether you have an innie or an outie has nothing to do with the handiwork of the physician who delivered you, explains Cetrulo. It's related to the presence of space between the skin and the abdominal wall, he says.May 16, 2011
Innie belly buttons are much more common than outies. But most of the time, outie formation is simply luck of the draw.
Some people don't have a belly button, and the reason for this may be related to surgical history or just an anomaly in how the belly button formed (or didn't, for that matter). Most of the time, if you don't have a belly button, it's related to a surgery or a medical condition you had when you were younger.Apr 16, 2020
When you're born, the umbilical cord is cut and you have a small piece left called the umbilical stump. One to 2 weeks after birth, this stump falls off and what remains is your belly button. As a result, your belly button is essentially a scar. Whether it's an innie or outie depends on how your skin grows as it heals.May 21, 2018
According to a study at the University of Missouri, small, T-shaped belly buttons are the most attractive. Researchers showed pictures of innies, outies, and belly buttons of all shapes and sizes to a group of men and women who rated them on a scale of 1 to 10 from least to most attractive.Apr 17, 2014
