How conjoined people control their bodies is amazing!

When we want to go to a party, we can just leave because our bodies belong entirely to us.

But there are a very small number of people in the world who are not so lucky. Their bodies cannot completely belong to one soul. They are conjoined people.

Conjoined twins (Siamese twins) are a human anomaly that has a low chance of survival because their lives depend on their physical connection to each other.

Despite the lack of scientific research on conjoined twins, medical knowledge about conjoined twins continues to grow with each surgery, autopsy, and laboratory test.

The lives of conjoined people are complex and emblematic of public intrigue, prompting experts or individuals to peek into their lives and ask questions about how their limbs feel, their brains think, their actions, etc. What is the activity like?

Why do conjoined people appear?

According to statistics, one in every 200,000 live births will give birth to a pair of conjoined twins. What is their chance of survival? Only 5 to 25.

According to data from the University of Maryland Medical Center, conjoined twins between 40 and 60 years old are stillborn, and another 35 years old conjoined twins only survive one day after birth, and very few of them can grow up to adults.

Identical twins occur when a fertilized egg divides and develops into two individuals. Typically around 8 to 12 days after pregnancy, the layers of embryos that will split into identical twins begin to develop into specific organs and structure.

It is generally believed that when the embryo divides beyond this time (usually 13 to 15 days after pregnancy) the division will stop before the entire process is completed, resulting in conjoined twins.

Another theory is that the two separate embryos may have somehow fused together during early development.

As for the formation of conjoined twins, there is no final medical conclusion yet, and the conditions of conjoined twins are also different.

Currently, there are nearly 12 different types of conjoined twins, but one of the most common conjoined twins is the thoracoabdominal conjoined twin (40) which is attached to the upper part of the torso.

They have identical hearts, so surgical separation is nearly impossible without one or both twins dying.

The second most common type of conjoined twins is connected from the sternum to the waist. It accounts for 33% of all conjoined twins. They may share the liver, gastrointestinal tract and reproductive organs, but rarely ***Enjoy your heart.

Experts are not sure why, but female conjoined twins are three times more likely to survive than male conjoined twins, which is why 70% of surviving conjoined twins are female.

How conjoined twins control their bodies

Conjoined twins cannot have true privacy in their lives, and being physically connected to their siblings through breasts, hips or heads changes them* **Exclusive type of body function.

Different types of conjoined twins share their bodies in different ways. The 98-year-old conjoined twins each have their own unique thoughts and feelings.

So it takes a long time for them to learn simple skills such as walking, because they require coordination of each other's bodies. But there are some exceptions.

For example, the Canadian conjoined sisters Tatiana and Krista Hogan were born with their heads connected, and their psychological processes influence each other. If one of the twins' legs is touched, both people will feel it.

As they write, their brains are prompted to predict the next word. It is said that Tatiana hates ketchup and Krista screams when she eats it.

Through MRI scans, doctors have determined that the thalamic pons connects the two sisters' sensory inputs together, forming a conscious circuit.

Essentially, if one person thinks a happy thought, the other person can perceive it. When one person sees an image through their eyes, another person receives it milliseconds later.

In addition, the Hansel conjoined sisters who were born in the United States in 1990 each have half of their body. They went to college together and learned to drive, swim, etc.

They are symmetrical conjoined twins with normal proportions, with their own hearts, stomachs, spines, lungs and spinal cords, but separate bladders, large intestines, livers, diaphragms and reproductive organs.

Unlike Tatiana and Krista, their touch is limited to half of their bodies. If one of the arms is touched, only one person can feel it.

From infancy, they must learn how to coordinate with each other to complete simple tasks such as clapping, crawling and eating.

What if one of the conjoined people dies and the other one dies?

The life span of conjoined twins is generally short, but there are some that are relatively long, such as Thailand’s famous conjoined twins Eng and Chang. When one dies, the other 3 He also died young.

When talking about the death of a conjoined person, it mostly depends on how they were joined together.

If they share a circulatory system or a vital organ, then after one of them dies, the other will not survive long.

Still, if they can be taken to a hospital with a skilled surgeon, the second person may be saved, and some conjoined people may even be separated after one of them dies.

Because the obstacle that separates them while they are both alive is usually that one of the twins is likely to die during the process or shortly thereafter because of the way organs and systems are distributed between the bodies. If a person dies, this barrier is removed.

But for someone like the Hensel sisters, who have their own vital organs and have completely different heads (and brains) at any age, surgery is impossible.

Finally

The earliest record of Siamese people in history is a pair of conjoined twins depicted by the Moche culture in ancient Peru. Those pottery can be traced back to 300 AD.

Society’s real concern for conjoined people can be traced back to the end of the 16th century. At that time, people were afraid of conjoined people and even believed that conjoined people did not have the qualifications of "human beings" (non-human beings). It is said) that no midwife ever delivered them, thinking that this would bring a curse.

Now, some of them are recognized by society for their abilities, and conjoined people should get the same respect!
