There are some disturbing facts about the human body, which may surprise you. These include cancerous tumors as well as brain-eating amoeba and hearing voices. Keep reading to learn more! These are some additional facts about the human brain!
Cases of cancerous tumors in the human body
Different types can cause cancer in the body. While some grow rapidly and spread throughout the body, others remain localized in one area. Depending on their location, cancers can be treated by chemotherapy or surgery. Cancers rarely spread beyond the body. But, they can spread if not treated.
While many types of cancer are still unknown, they are generally classified according the type of cell involved. Carcinomas account for 90% of all cancers. Sarcoma, a rare type of cancer, is also a common form. It is characterized as solid tumors that grow in connective tissues. Lymphomas arise from immune system cells.
Brain-eating amoeba cases in our waters
Naegleria fowleri, a brain-eating amoeba, is well-known for causing severe illness. It can enter the body through your nose, travel to the brain and kill brain tissue. This pathogen is deadly and can even cause death. It can spread easily through water systems. It has been a rising concern among young people.
This single-celled organism lives in warm, fresh water and the earth. People can get severe headaches and fever from breathing in contaminated water. Some people may experience stiff necks and seizures. In rare cases, patients may even go into a coma. These symptoms are caused due to toxic compounds that build up in brains from infection.
The human body can hear voices
Hearing voices is a common experience that can affect people's lives in many different ways. Some people find these voices encouraging and positive. Others are afraidful or threatening voices. Others hear voices that they believe are related to someone they loved or someone they lost.
Researchers looked at the auditory cortex, both in healthy subjects as well as patients suffering from schizophrenia. This is the area responsible for hearing sound. It is formed in infancy. This brain area is crucial for hearing sound. However, it doesn't rely on higher-order cognitive functions.
Bacteria in the belly button
The bacterial communities of the belly button are diverse just like those in other parts. Each belly button was home to 67 distinct bacterial species. Although some taxa in the belly button look similar to those on the skin, they are quite different.
Candida infections can develop in the belly button of people with high blood sugar. People who are diabetics are also at a higher risk for developing bacterial infections. Dead skin cells or sebum may also be a source of contamination. This can result in stone-like bodies within the umbilicus.
FAQ
What is the most interesting fact about the human body?
We have two eyes, two ears, two nostrils, four limbs, a mouth, a nose, and a penis. Yes, more than 50 parts to our bodies. But one thing is missing. A heart.
A heart is the pump that circulates blood throughout a body. The blood moves through the veins. It transports oxygen and nutrients to your cells. It also removes carbon dioxide.
The heart pumps about 5 liters blood per minute. This is equivalent to a person drinking 2-3 cups coffee daily.
The heart pumps blood 24 hours a days, 365 days per year. Your heart beats nearly 100 times a minute while sleeping.
Color of your skin is a good indicator of whether someone is healthy. If you examine the skin closely, you will see tiny blood vessels called capillaries. These vessels carry blood back to the heart from the large blood vessels beneath the skin. The skin becomes blue-colored or purple when blood flow is restricted.
Red blood cells are not available to sickle cell patients. Their blood becomes sticky and hardens, causing them to become very ill.
To stop bleeding from a cut, you can apply a bandage to the wound. For the wound to heal properly, blood must continue to flow. To do this, doctors insert a needle through the skin into the vein next to the injury. This allows the blood to drain from the injured area.
Doctors also insert tubes (catheters) into the artery near the site where the blood clot forms. This keeps patients alive until the clot has broken up naturally.
How does your brain control the functions within your body?
To ensure that they work together, messages are sent by the brain to other organs. Your body's functions are controlled by your brain. It tells your stomach how to digest food and your lungs how to inhale oxygen; it also tells your arms, legs and feet to move.
Your brain is made up billions of nerve cell networks connected in groups known as neurons. Neurons communicate with each other by sending electrical signals called action potentials on axons. Each neuron has its own cell membrane around its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. The neuron fires when there is ion movement.
Neurotransmitters, chemical substances that are released when a neuron fires. Neurotransmitters attach to the receptors of the second neuron and open ions channels for ions to pass in and out. This causes the second neuron to fire too.
Neurotransmitter release occurs when the presynaptic neuron receives an impulse from another neuron. The impulse travels along the synaptic pathway that connects both neurons. The transmitter binds directly to the receptors in the postsynaptic nervous neuron, and triggers the firing.
Neurotransmitters are important for communication within the nervous system. They coordinate activity between the different parts of your brain.
What are 5 interesting facts about the liver?
The liver is responsible for breaking down toxins and storing vitamins and minerals. It helps maintain a steady body temperature and regulates blood pressure.
How often do we hear someone say, 'I feel sluggish today' or 'my head feels heavy'? These symptoms could be signs of liver problems.
Some common signs include dark urine, yellowing skin, fatigue, nausea, vomiting, loss of appetite, stomach cramps, jaundice (yellow coloration), and itching. But these aren't the only warning signs. If you feel any of these warning signs, consult your doctor immediately.
The liver plays a crucial role in our lives. It is responsible for detoxification as well digestion, metabolism and immunity.
-
The average adult liver weights about 1,400g.
-
At birth, the liver of a baby can be half as big as an adult's. By age three, it is about four times larger than that of an infant.
-
The liver is located on the left side, just below your rib cage.
-
The liver is divided into 16 major lobes. However, there are many smaller lobules that are within these lobes.
-
The liver contains about 10 million individual red blood cells.
Which is the most secretive city in the world?
You might be surprised at the answer. It could even make you uncomfortable, because it challenges how reality is perceived and lived. However, there's a reason for this place to exist. It's not what we would expect.
It was called the City of God by ancient Greeks. It was also called the City of Destruction in the Bible.
It's known in India as Kashi (Kashmir). It's also known as Novgorod in Russia.
But here in America, it goes by another name - The Town That Disappeared.
A small community of 1200 people in western New York State vanished. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.
This little community vanished and no trace remains to indicate where or when it disappeared. Some say the earth swallowed it up. Some claim it was destroyed by a meteorite impact. Some claim that it was destroyed by a meteorite strike. Others still believe it was stolen away by aliens.
Regardless of what happened, residents of this once-thriving town are certain that their town won't be forgotten forever. They just moved to another city.
A website is available to track the disappearance and recovery of Zugspitz, which was lost in the Great Depression.
So, where exactly did this town go? Well, it's in Switzerland!
Zugspitze lies on the border between Austria and Germany. Lake Zugspitze lies just above the summit of the mountain.
It has always fascinated my that so many towns have disappeared but others still exist. What is the difference between some towns that disappear and others that survive? I decided that I would investigate.
I wanted more information about the mysterious disappearing of towns. What causes a community to disappear? How does one place go extinct?
It turns out that there are several theories about the phenomenon of vanishing towns. One theory is that a city disappears after all buildings have been demolished. Another theory holds that the town simply relocates to another location. Another theory suggests that the town has never existed.
There are many theories, but the truth is that thousands of towns around the world have been submerged by the earth. This video examines the history and current status of these places.
