Belly buttons, those little indentations or protrusions on our abdomen, come in all shapes and sizes. While most people have what is commonly known as an “innie,” there is a small percentage of the population that sports the elusive “outie” belly button. In this article, we will explore the different types of belly buttons and delve into the fascinating world of rare belly button shapes.
Let’s start with the majority – the innies. Innies are the most common type of belly button, with approximately 90% of people sporting this inward-dipping navel. This dip occurs when the abdominal wall muscles close around the umbilical cord stump during fetal development, leaving a small hollow in the center of the abdomen. Innies can vary in depth and shape, from shallow indentations to deeper, more pronounced dips.
On the other hand, outies, or protruding belly buttons, are a rare sight, found in only about 10% of the population. Outies occur when the umbilical cord stump does not retract fully into the abdomen, leaving a small protrusion. This can happen due to various factors, including the way the cord was clamped after birth. Some people with outies may have a small piece of the umbilical cord still attached, causing the belly button to stick out slightly.
Interestingly, the attractiveness of belly button shapes has been the subject of scientific study. Researchers at the University of Missouri conducted a study where participants were shown pictures of innies, outies, and various other belly button shapes. They were then asked to rate them on a scale of 1 to 10 based on attractiveness. Surprisingly, small, T-shaped belly buttons were found to be the most attractive among both men and women.
The rarity of outie belly buttons has led to various theories and old wives’ tales about their origins. One such theory suggests that doctors’ techniques during the clamping of the umbilical cord may contribute to the formation of outies. However, there is no concrete evidence to support this claim, and the exact reasons behind the development of outie belly buttons remain a mystery.
Belly buttons come in different shapes and sizes, with innies being the most common and outies being a rare sight. While the majority of people sport an inward-dipping navel, a small percentage of the population has a protruding belly button. Interestingly, small, T-shaped belly buttons have been found to be the most attractive in scientific studies. However, beauty is subjective, and personal preferences may vary. The mystery behind the development of outie belly buttons continues to intrigue scientists and remains an area of further research.
What Is The Most Attractive Type Of Belly Button?
According to a study conducted at the University of Missouri, researchers found that small, T-shaped belly buttons are considered the most attractive. In this study, a group of men and women were shown various pictures of belly buttons, including innies, outies, and belly buttons of different shapes and sizes. They were then asked to rate these belly buttons on a scale of 1 to 10, based on their level of attractiveness.
The study concluded that the participants consistently rated the small, T-shaped belly buttons as the most attractive. It is important to note that attractiveness is subjective and can vary from person to person. However, this study provides insight into general preferences when it comes to belly buttons.
Here are some key points to summarize the findings of the study:
– Small, T-shaped belly buttons were considered the most attractive.
– The study involved a group of men and women who rated various belly buttons on a scale of 1 to 10.
– Attractiveness is subjective and can vary among individuals.
– The study provides insight into general preferences regarding belly buttons.
It is worth mentioning that personal preferences may differ, and beauty standards can vary across cultures and individuals. This study offers a glimpse into the preferences of the participants involved, but it is important to remember that beauty is subjective and can differ from person to person.
What Is The Rarest Belly Button Shape?
The rarest belly button shape is known as an “outie.” This unique shape occurs in approximately 10% of the population, with the remaining 90% having an “innie” belly button. An outie belly button is characterized by a protrusion of the navel or a piece of the umbilical cord that remains after it is clamped during birth. Instead of retracting back into the abdomen, the outie belly button pokes out slightly. This distinctive shape sets it apart from the more common innie belly button.
How Many Different Types Of Belly Buttons Are There?
There are several different types of belly buttons, each with its own unique characteristics. Here is a list of the most common types:
1. Innie: This is the most common type of belly button, where the navel is indented or concave, appearing as a small depression on the abdomen.
2. Outie: In contrast to an innie, an outie belly button protrudes outward, often due to excess skin or a small umbilical hernia.
3. T-Shaped: As the name suggests, this type of belly button has a vertical ridge that intersects with a horizontal ridge, forming a T-shape.
4. Oval: An oval-shaped belly button is elongated and usually wider in the middle than at the top and bottom.
5. Vertical: A vertical belly button is characterized by a long, narrow shape that runs vertically along the abdomen.
6. Round: A round belly button is symmetrical in shape and appears as a circular indentation on the abdomen.
7. Horizontal: Similar to the vertical belly button, a horizontal belly button is elongated but runs horizontally across the abdomen.
8. Deep: Some people have very deep belly buttons, where the indentation appears to be more pronounced and extends further into the abdomen.
9. Shallow: On the other hand, shallow belly buttons have a less noticeable indentation and may appear more flat than concave.
10. Hooded: A hooded belly button is partially covered by skin, giving it a hood-like appearance.
It’s important to note that these are just general descriptions, and belly buttons can vary in shape and size among individuals. Additionally, some people may have unique belly button variations that do not fit into any specific category.
How Rare Is A Belly Button?
A belly button, also known as the navel or umbilicus, is a small and unique feature found on the abdomen of most humans. The vast majority of people have what is called an “innie” belly button, which is characterized by a small depression or dip inward. This is the more common type of belly button, with approximately 90% of the population having innies.
On the other hand, around 10% of the population has a protruding belly button, known as an “outie.” These outies are less common and can be seen as a small bulge or protrusion from the abdominal area. They are roughly as rare as left-handedness, which is also found in about 10% of the population.
It is important to note that having an outie belly button is not considered abnormal or a cause for concern. It is simply a natural variation in the appearance of belly buttons. Contrary to a longstanding theory or old wives’ tale, the presence of outies is not typically attributed to doctors’ techniques during childbirth or any external factors. It is largely determined by the structure of the umbilical cord and how it heals after birth.
While innie belly buttons are the most common type, outies can be found in approximately 10% of the population. They are a natural variation and not a result of medical interventions or techniques.
Conclusion
Belly buttons come in various shapes and sizes, with the majority of people having innies and a smaller percentage having outies. According to a study conducted at the University of Missouri, small, T-shaped belly buttons are considered the most attractive. However, it is important to note that the shape of one’s belly button is largely a matter of chance and not influenced by doctors’ techniques as previously believed.
The classification of belly buttons into innies and outies is based on whether they go inward or stick out. Innies, which dip inward, are the most common type, with around 90 percent of people having this shape. On the other hand, outies, or protruding belly buttons, are found in approximately 10 percent of the population. They occur when the piece of umbilical cord left after the nub is clamped pokes out slightly instead of retracting back into the abdomen.
While there is a preference for small, T-shaped belly buttons in terms of attractiveness, it is important to remember that beauty standards can vary among individuals and cultures. Ultimately, the shape of one’s belly button should not be a cause for concern or insecurity, as it is a natural and unique aspect of our bodies.
