The Human Body: Some Unusual Facts

It is fascinating to discover bizarre facts about the human body. An example is that the adult human skeleton changes every ten years. It is composed of four blood groups and 206 bone. Two kidneys also exist. In reality, the human body may be the most complex thing on Earth.

The adult human skeleton changes every ten year

The human skeleton is constantly in constant remodeling and rebuilding throughout adulthood. Bone remodeling and repair is a key function of bone cells. Nearly 100% of the bone tissue within a human body is replaced during a person's lifetime. 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 two lungs

Two lungs (or lobes) are found in the chest cavity. These organs exchange oxygen 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, which are thin, light and elastic, provide an air filter system. They allow air to pass through the nose and mouth into the lungs.

It has two earlobes

Despite being similar, the human ears are quite different. The complex network of structures in the earlobe allow us to hear, see, and move. Men's ears are typically larger than women's ears. The average ear length, at 2.5 inches, is 0.74 inches and 0.77 inch respectively. According to studies, the ear lobes grow larger as we age.

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 you your stomach to digest food; your lungs to inhale air; and it tells you your arms and legs how to move.

Your brain is made of billions, or neurons, of nerve cells. Action potentials are electrical signals that neurons send to one another. 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. Ion movement creates the electric charge that causes the neuron to fire.

Neurotransmitters, which are chemicals that release neurotransmitters when a neuron fires up, can be found in the space between the neurons and the next one. Neurotransmitters bind with receptors on the second nerve cell, opening ion channel channels to allow ions in and out. In turn, the second neuron also fires.

When a presynaptic nerve receives an impulse, neurotransmitter release takes place. An impulse travels along a synapse that connects the two neurons. The transmitter binds to the receptors on the postsynaptic neural cell, which triggers the firing of that neuron.

The nervous system relies on neurotransmitters for communication. They are also responsible for coordinating activity between various parts of the brain.

What is your most secretive community?

The answer to that question may shock you. This may make you feel uncomfortable as it challenges your perception of reality and the way we live. But there is an explanation for why this place exists, and it's not what you would expect.

It was called the City of God by ancient Greeks. According to the Bible, it was called the City of Destruction.

It's known in India as Kashi (Kashmir). It's also known as Novgorod in Russia.

However, in America it is called The Town that Disappeared.

One small community in western New York State with 1,200 residents vanished without a trace. With the exception of a road marker pointing to its former site, there were no remains: cars, bodies, houses.

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 say it was destroyed in a meteorite collision. Still, others say aliens took it away.

The residents of this once prosperous community believe that whatever happened, their town is not gone forever. They had just moved from one town to the other.

There's even a website that tracks the disappearances and recoveries of Zugspitz.

You might be wondering where this town went. Well, it's in Switzerland!

Zugspitze lies on the border between Austria and Germany. The lake Lake Zugspitze is just beyond the mountain's summit.

It's always fascinated me how so many towns disappear, yet others remain. Why does some vanish while others remain? I decided that I would investigate.

I was curious about the disappearing towns. What causes a community to disappear? What makes a place disappear?

There are several theories behind the disappearing of towns. One theory states that a town vanishes when all its buildings are destroyed. Another theory states that the town simply moves to another location. Another theory suggests that the town has never existed.

Theories aside, the fact remains that dozens of towns around the globe have been swallowed up by the ground. This video examines the history and current status of these places.

What dark secrets do Hollywood have?

Hollywood is filled secret societies. There are many secret societies in Hollywood. Some are cult-like, where members adhere to strict rules and rituals. Others are clubs for people who share similar interests.

Some of the most powerful organizations in the industry are even more dangerous. These include the MPAA (Motion Picture Association of America), the organization that sets film ratings and RIAA(Recording Industry Association of America), the company that sets music licensing fees.

Numerous unions, guilds, and associations represent actors, writers, producers, editors, and other creative professionals. Many of the major TV networks and movie studios are owned or controlled by large corporations.

It doesn't matter how secretive a group might seem, someone somewhere knows what they are doing. However, we shouldn't fear them.

Instead, we should embrace and celebrate them. Because they help us make better choices.

They can tell us which movies and songs are likely to be successful, as well as what books and novels will be most popular.

They help us make decisions about what we will buy, watch, listen to, or read.

We can trust them so we can ignore their advice when it doesn't suit our taste.

Because we have chosen to ignore their power, they are even more powerful. They are the ultimate arbiters and judges of taste.

You can ignore them if they don't agree with you.

Let's now look at some lesser-known, but still very real Hollywood secret organizations.

Observe why they are important.
