Weird facts about the human body are fascinating to learn. An example is that the adult human skeleton changes every ten years. It has four blood categories and 206 joints. Two kidneys also exist. In reality, the human body may be the most complex thing on Earth.
Every ten years, a adult's skeleton gets replaced.
The human skull undergoes constant remodeling and rebuilding through adulthood. Bone cell function is crucial in bone remodeling and repair. Nearly 100 percent of bone tissue in a person's body will be replaced over the course of their lives. Bone cells are called osteoblasts, and they break down old bones and form new ones in their place. This process, known as bone remodeling is measured using a bone density measurement.
It has 2 lungs.
The human body has two lungs, or lobes, that are located in the chest cavity. These organs can exchange air and remove carbon dioxide. The pleura is a membrane that surrounds each lung. It is connected to the heart via the main bronchus. Pleural membranes are thin and flexible, and act as an air filter. They allow air to pass through the nose and mouth into the lungs.
It has 2 earlobes
Despite being similar, the human ears are quite different. The earlobe is a complex system of structures that allow us to hear and walk. Men's ears are usually larger than those of women. The average length of the ear is 2.5 inches. Also, the ear lobes are 0.74 inches long by 0.77 inches wide. According to research, the size and width of the ear lobes increase with age.
FAQ
Is there a Hollywood blacklist of actors?
There is a Hollywood blacklist.
But, the list has not been made public. As far as we know, the names aren't even known. This is why it matters.
The secret reason is that directors and actors who are on the blacklist would not be able to find employment. The studios would be out of business as they lose money. This would mean that they would cut back on movie production. This would lead to fewer opportunities and less money for blacklisted directors. This would make them bankrupt.
This could lead to more victims.
In other words, if someone is trying to make an Oscar winning movie, they might have to sign a contract that says they won't speak openly against their employers. The same goes for any director or producer who wants to get nominated for an award.
This is why you'll hear about directors being pressured by producers to take scenes out of their films. Directors may threaten to quit projects that don’t align with their vision.
This is why Hollywood has a blacklist. Negative comments about your employer will most likely lead to you being unemployed. This is bad news for anyone.
It is not uncommon for people to be falsely accused. It's been a struggle to get their names cleared.
We must stop this from happening again. Everyone should have the right to speak freely.
Therefore, it is necessary to eliminate the Hollywood blacklist.
How does your brain control your body's functions?
To ensure that they work together, messages are sent by the brain to other organs. Your brain controls all that happens in your body. It tells both your stomach and lungs what to do; it also controls your legs and arms.
Your brain is made up of billions upon billions of nerve cells that are connected together in groups called neuronal groups. Action potentials, which are electrical signals sent by neurons to each other via axons, allow them to communicate with one another. Each neuron has a cell membrane surrounding its nucleus. There are channels within the membrane that allow ions such a sodium or potassium to enter and exit the cell. Ion movement is what causes the neurons to fire.
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. As a result, second neuron fires as well.
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 at the receptors of the post-synaptic Neuron and triggers its firing.
Neurotransmitters are important for communication within the nervous system. They are also responsible for coordinating activity between various parts of the brain.
Why are actors blacklisted?
If you are an actor, you will get more rejection than if you are a writer. You will likely be rejected many times if you are an actor. It doesn't matter if you get rejected a lot because eventually you'll meet someone you love.
Actors have a lot of talent, so they can make a decent living almost anywhere. But most actors don't want to make a lot of money. Actors love acting, and love telling stories. So if you're an actor, chances are you're going to put yourself out there.
You might even go to auditions where you're told that you're too old, too young, or not right for the role. Sometimes, you may lose an audition for a movie. This happens all the time.
But once you've been cast, you may also face criticism. Some people will say that you look awful or shouldn't wear makeup. If you're lucky, you won't even hear negative comments.
Sometimes your character isn't real or authentic and you will be criticised. Maybe you play a gay man, and everyone thinks you're straight. You could also play a woman with a tendency to cry a lot, even though she's supposed to be tough.
Maybe you are asked to change your vocal chords. Sometimes they ask you to sound like either a boy or a girl. They want you to sound better most of the time.
The best way to deal with these criticisms is to ignore them. Actors sometimes feel like failures when they hear they were wrong. But the truth is that they haven't done anything wrong.
They just weren't born with the talent that made them famous. They may not fit the bill sometimes, no mater how hard they try.
Blacklisting an actor could be for many reasons. Some people don't like actors. Others feel that actors are lazy. Still, others say that actors are cheaters.
It doesn't matter what reason it may be, you won’t be banned if you keep trying. There are many opportunities for you to find your role.
As long as you keep trying, you'll eventually succeed.
Is there a more mysterious place than the Earth itself?
Antarctica is home to the most mysterious and remote place on Earth.
What is it that makes this place so interesting? Because it's unlike any other place in the world.
It is remote and difficult to reach. But there is more to this site than meets the eye.
This natural wonder is also home to some of the strangest wildlife species.
Let's see how this incredible destination became famous for its mystery.
Antarctica: The South Pole
Antarctica is named for no one. Some believe it refers to "land of ice". Others believe it derives from Greek mythology.
In ancient Greece, Antarktis was the name given to the island where Zeus' twin brothers were born. According to some legends, one of these twins was born in winter. Therefore, the name antarctic.
Others believe that the name is a combination of the Greek words anti and tropos which mean against and turn. This would translate to land that is turned away from the sun.
No matter the reason, Antarctica is a place that has always fascinated people.
It is the coldest, windiest, driest and highest continent. There are no trees, plants, or animals here because it is too cold.
This frozen wasteland is still alive.
Here are about 90% of all the living creatures on Earth. Here are approximately 50% of all the animal and plant species in the world.
And what makes Antarctica such a unique environment? Here, water freezes and becomes ice instead of evaporated into the air.
This causes large amounts of ice to float above ground.
These floating glaciers cover over 80%. These glaciers are getting larger each year.
So far, the Antarctic ice sheet has grown 60 feet since 1960.
If the melting continues, the sea level will rise by up to 200 feet. This could lead to widespread flooding.
This does not mean that everyone is wrong. Some scientists think global warming might be beneficial. They say that as temperatures rise, the ice sheets might melt faster, causing floods that flush out tons of toxic chemicals from our soil and bodies.
Others cautioned that this theory sounds too science fiction.
Statistics
- In one 2014 study published in the Archives of Medical Science that sought to study the prevalence of these mites, research showed that 41% of the people had them hanging out in their eyelashes. (romper.com)
- You spend about 10% of your time awake blinking (romper.com)
- A 2012 paper published in the Proceedings of the National Academy of Sciences reported that people blink about 15 to 20 times each minute, meaning, if you do the math, you spend about 10% of the time that you're awake blinking. (romper.com)
- "It is estimated that 75% of people have at least mild gum disease, with the most common symptoms being bleeding when brushing, bad breath, and dark and swollen gums," Dr. Ron Baise, a London-based dentist, tells Romper. (romper.com)
- According to a 2018 study published in Free Radical Biology & Medicine, this is because blood pressure is regulated by our innate circadian rhythm and internal clock. (romper.com)

Hollywood scandals that stunned the world
There's nothing more shocking than watching someone become famous for the wrong reasons. But, it's equally shocking to watch them fall from the graces.
It's fascinating to see how industries react to their mistakes. There are many stories about celebrities who drank excessively. Some even died young because of it.
But, the worst part? When those stars openly discuss their issues and are ignored by everyone. Last week, that's exactly where we were.
Heath Ledger, after a long and successful professional career, finally gave in to his demons. He took too many prescription pills and died shortly after.
His family and close friends had difficulty accepting his death. The media took to him publically.
Heath was once regarded as one of the best actors today. Two Academy Awards nominations went to Heath for his performance on Brokeback Mountain.
Heath was not only an actor, but also directed and wrote films like A Knight's Tale and Monster's Ball.
Hollywood loved Heath, however he soon grew too big for his good looks. He started to use drugs and drink heavily. He was eventually able to get clean and went to rehab.
Now that he was sober, he wanted to make amends. He created a documentary called Room 237, which documented the making of The Shining. It was supposed that it would be released this year but it won't make its debut in theaters until next.
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. However, it would have been nice if he could have gotten some help before things spiraled out of control.
We hope Heath's story warns others who might think they can still have it all.
