Thanks to thousands and thousands of years of evolution, the human body has develop into an authority in its growth process. Most of the time, this provides us the precise variety of organs and structures we'd like to work with. But sometimes, hiccups in the method mean people find yourself with extras.
Accessory teeth, fingers, toes and nipples are literally surprisingly common.
as much as 1% of the population Born with extra fingers or toes, while around 1% people Are born with extra teeth. These are each phenomena. More common in men — especially the additional digits, that are Usually twice In men
about 6% People have an additional nipple. They can appear anywhere along the road that runs from the armpit to the groin – often called Mammary ridges or milk lines.. As with extra teeth and digits, there are abnormal nipples. More common in men, however it will not be clear why. They also appear on the left side of the body.
But these aren't the one places where extra body parts can appear. Some individuals are born with extra bones, organs or genitalia that they could not even know they've.
The ribs
Supernumerary ribs are often seen in two places: the neck or the lumbar region (lower back). An estimated 1% of the population has an additional rib – although in relation to an additional rib within the neck it may very well be closer. 4.5%. An extra rib could be on one or each side of the spine.
An extra rib normally doesn't cause any problems and is just there. casually inquired Imaging during an X-ray or for an additional condition – although this may cause damage if it presses on neighboring nerves and blood vessels.
If it occurs within the neck, it will possibly cause Pain, numbness and tingling In the lumbar region within the arms, the additional ribs can Causes back pain.
Abdominal organs
An enlarged spleen is surprisingly common. Between 19% And 30% People have a tool spleen.
They are commonly found. Near the central spleen – but could be pulled down on the waist in some situations. Accessory spleens can present clinical challenges in the event that they require surgical removal in treatment. Hemolytic anemiawhere red blood cells are destroyed faster than they're made.
The liver is the biggest organ of the stomach which consists of 4 distinct parts (lobes). lower than 1% people It is reported that they're born with an adjunct lobe of the liver – although this number could also be higher, as having an adjunct lobe normally causes zero symptoms. Most individuals who have an additional liver lobe discover it by chance—either during or after surgery Surgery or Imaging For a variant.

But accessories are lobe cases that cause torsion. After blunt force trauma. This cuts off the blood supply and requires Emergency surgery.
Abnormal kidneys may also occur – although that is Incredibly rare, with fewer than 100 reported cases on record. Again, this may increasingly be because they don't cause health problems. The rarest can be the rarest: had a recent baby. Born with two abnormal kidneys.making a complete of 4.
However, what's more common is having a duplex kidney – where an additional tube comes from the kidney that connects to the bladder. as much as 6% of the population There is one
Genitalia
There are various genetic abnormalities that may occur. This is as a consequence of the incontrovertible fact that the testes and ovaries develop on each side of the body, which makes it possible for the supporting structures to fuse incompletely during normal development, resulting in abnormal genitalia. .
A double uterus occurs in approx. 0.3% women, a really rare occurrence. Each uterus could have its own cervix and vagina (or may share a vagina). Each uterus is normally able to carrying a healthy one. Fetuses at the same time – Although related to a double uterus High risk Miscarriage, premature delivery, breech delivery and stillbirth.
Extra ovaries It may also occur in rare cases. Often these are found. Very high in the stomach or Around the kidneyswhere they'll. Tumors form.
Males can be born with extra genitalia. Diphalia refers to being born with two penises – a condition that happens in One in every 5 million to 6 million births. each The case is uniqueWith different size, shape and functionality.
Recently, it was also reported that a baby boy was born Three penises (triphalia) – although just one had all of the vital tubes to urinate.
Abnormal testes (polyorchidism) can also be seen, with three being essentially the most common abnormality – with an additional one normally present. On the left side In all of history, there have only been seven reported cases of it happening to an individual. Born with four testicles.. Extra testicles don't cause problems until they descend into the scrotum, which involves The risk of testicular cancer increases..
Double bladder There is an incredibly rare copy, with only 50 known cases.
Additional organs
Extra organs (polymyelia) are one in all the rarest supernormal structures seen in humans. It occurs almost exclusively within the upper limbs. Six times more often in comparison with the lower limbs.
In the upper body, these accessory organs are inclined to be Move from the shoulderwhile the lower a part of the body has extra legs. Extending from the pelvis. Extra feet can be.
Even under rare circumstances, an additional limb may grow In the middle of the back – often called “Notomelia”. But the rarest is “cephalomyelia” – where a baby is born with a limb. Growing from the head. In these cases, surgery shall be required to remove the additional organ.
Abnormal structures of every kind normally don't harm our health. In many cases, they are only one other thing that makes every person unique.
