FAQ
How does the brain control the functions of your body?
The brain sends messages to other organs and muscles to ensure they work together. Everything that happens within your body is controlled by the brain. It tells the stomach to digest food, and the lungs to breath air. It also tells your legs and arms to move.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Action potentials on Axons are an electrical signal that neurons send to each other. Every neuron has a cell wall around its nucleus. The membrane contains channels that allow ions like sodium and potassium to enter the cell and leave it. Ion movement is what causes the neurons to fire.
Neurotransmitters are chemicals 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. As a result, second neuron fires as well.
Neurotransmitter releases occur when a presynaptic neurons receives an input from another neuron. An impulse travels along a synaptic link between the two neuron. The transmitter binds with the receptors of the postsynaptic nerve, activating the firing of the postsynaptic neurons.
Neurotransmitters are important for communication within the nervous system. They are also responsible for coordinating activity between various parts of the brain.
What is the most fascinating fact about the human body
We have two eyes and two ears, two nostrils each, four limbs, four limbs and a penis. We have over 50 parts of our bodies. However, one thing is missing. The heart.
A heart is a pump that circulates blood throughout the body. The blood moves through the arteries and veins to transport oxygen and nutrients into the cells, and remove carbon dioxide.
The heart pumps out approximately 5 liters of blood per minute. This is equivalent in daily coffee consumption to an adult who consumes approximately 2 to 3 cups.
Blood flows throughout the heart 24 hours per day, 365 Days a Year. When you're asleep, your heart beats approximately 100 times per hour.
Color of your skin is a good indicator of whether someone is healthy. You can see tiny blood vessels, called capillaries, when you look closely at the skin. These vessels carry blood away to the heart via the large blood vessels. If blood flow is blocked, skin can turn blue or purple.
People with sickle cells lack red blood cell. They become very sick when their blood becomes hardened and sticky.
A bandage can be used to stop bleeding if you have cut your own skin. Blood must flow in order for the wound to heal properly. To do this, doctors will insert a needle through your skin into the vein adjacent to the injury. This allows blood drainage from the injury area.
Doctors may also insert catheters (catheters), in an artery to treat a blood clot. This keeps the patient occupied until the clot is broken down naturally.
What is the most secretive place in the world, and why?
The answer to that question may shock you. It could even make you uncomfortable, because it challenges how reality is perceived and lived. There is a reason this place exists and it's not as you might expect.
It was also called the City of God in ancient Greek. In the Bible, it was known as the City of Destruction.
It's known in India as Kashi (Kashmir). It is called Novgorod (Russia).
However, in America it is called The Town that Disappeared.
One small New York State town with just 1,200 people vanished. A road sign pointing to the former location of the town was all that was left, except for a few bodies and cars.
This tiny community disappeared without leaving any clues as to where it went or when. Some say it was swallowed up by the Earth. Others believe it was destroyed by a meteorite. Others claim it was taken away by aliens.
The people of this once-thriving community, however, are positive that the town won't disappear forever. They had just moved to another town.
Even a website exists to help track down the disappearances of the lost city Zugspitz.
So, where exactly did this town go? It's actually in Switzerland!
You can find Zugspitze at the border of Austria and Germany. A huge lake, Lake Zugspitze, is located just beyond the summit.
It has always fascinated and astonished me to see how many towns have vanished but still exist. Why does some vanish while others remain? I decided that I would investigate.
I wanted to know more about the mysterious disappearing towns. What causes a town to disappear? How does one place go extinct?
There are many theories regarding the phenomenon of towns disappearing. One theory states that a town vanishes when all its buildings are destroyed. Another theory states that the town simply moves to another location. The third theory is that the town was never actually there.
There are many theories, but the truth is that thousands of towns around the world have been submerged by the earth. This video examines both the history and current status.
Here are 5 fascinating facts about the liver
The liver is responsible to detoxify toxins and store vitamins and minerals. It also regulates blood pressure, and maintains our body's temperature.

Hollywood scandals that stunned the world
Nothing is more shocking that seeing someone be famous for their wrong reasons. However, there is nothing worse than watching them fall from grace.
It's fascinating to see how industries react to their mistakes. We've all heard about celebrities who took too much alcohol and drugs. Some even died young because of it.
But the worst part is when those same stars go public with their problems and are shunned by everyone. This is where we ended up last week.
After a long and successful career, Heath Ledger finally succumbed to his demons. After a short battle with death, Heath Ledger succumbed to prescription pills.
His family and friends were unable to accept his death, and the media was quick to criticize him.
Heath was once considered one of the most talented actors working today. His performances in Brokeback Mountain earned Heath two Academy Award nominations.
In addition to acting, Heath also wrote and directed films, including A Knight's Tale, Monster's Ball, and Iron Man 3.
Hollywood loved Heath, but he became too big for his britches. He began using drugs and drinking heavily. He eventually went to rehab and was clean.
Now that he was sober, it was time to make amends. So he made a documentary called "Room 237," which chronicled the making of The Shining. The film was originally supposed to be released in this year's theaters, but it will not make its way into the cinemas until next year.
Heath tried unsuccessfully to get into Hollywood again, but nothing happened. He was actually arrested twice for drug charges.
We're not saying Heath should have been allowed back into show business. It would have been nice for him to have received some assistance before things spiraled outof control.
We hope Heath’s tale will be a wakeup call to anyone who may believe that they can still have all.
