Did you know that ... the strongest bone in the human body is the Jaw! The hardest bone in humans What is the strongest bone in the body.

could make up a whole chapter in the Guinness Book of Records. Among them there are champions who can surprise any skeptic. In addition to the fact that bones protect internal organs and form a skeleton to which muscles and ligaments are attached, due to which a person performs various movements, leukocytes and erythrocytes are produced in them. For 70 years of life, they supply the body with 650 kg of erythrocytes and 1 ton of leukocytes.

1. Each person has an individual number of bones. Not a single academician can answer exactly how many of them are in the body. The fact is that some people have "extra" bones - the sixth finger, cervical ribs, besides, with age, the bones are able to grow together and enlarge. At birth, a baby has over 300 bones, which makes it easier for him to pass through birth canal. Over the years, small bones grow together, and in an adult there are more than 200 of them.
2. Bones not white color . The natural color of the bones has tones of a brown palette from beige to light brown. In the museum, you can often find white specimens, this is achieved by their purification and digestion.
3. Bones are the only solid material in the body. They are stronger than steel, but much lighter than steel. If we consisted of steel bones, then the weight of the skeleton reached 240 kg.
4. The most long bone in the body - femoral. It makes up ¼ of the entire human height and is able to withstand a pressure load of up to 1500 kg.

5. The femur grows in breadth. When weight is gained, it thickens, which allows it not to bend or break under the weight of a person's weight.
6. The smallest and lightest bones - auditory - anvil, hammer, stirrup. Each of them weighs only 0.02 g. These are the only bones that do not change their size from birth.
7. The strongest is the tibia. It is the bones of the legs that hold the record for strength, since they not only have to withstand the weight of the owner, but also carry it from place to place. The tibia can withstand compression up to 4 thousand kg, while the femur up to 3 thousand kg.

8. Most brittle bones man has ribs. The 5–8 pair do not have connecting cartilage, so even with a moderate impact, they can break.
9. The most "bony" part of the body - the hands along with the wrists. It consists of 54 bones, thanks to which a person plays the piano, smartphone, writes.
10. Children don't have kneecaps. In a child under 3 years old, instead of a cup, there is soft cartilage, which hardens over time. This process is called ossification.
11. An extra rib is a common anomaly in humans.. Every 20th person grows an extra pair. An adult usually has 24 ribs (12 pairs), but sometimes one or more pairs of ribs grow from the base of the neck, which are called cervical. In men, this anomaly occurs 3 times more often than in women. Sometimes it causes health problems.
12. Bones are constantly updated. Bone renewal occurs continuously, so it has both old and new cells at the same time. On average, it takes 7-10 years to completely update. Over the years, the process slows down, which affects the condition of the bones. They become brittle and thin.
13. Hyoid bone - autonomous. Each bone is connected to other bones, forming a complete skeleton, except for the hyoid. It has a horseshoe shape and is located between the chin and the thyroid cartilage. Thanks to the hyoid, palatine bones and jaws, a person speaks and chews.

Incredible Facts

Muscles and bones provide structure to our body and allow us to jump, run, or simply lie on the couch.

We have 17 muscles to smile and 43 to to frown. Therefore, this is an extremely extensive and diverse topic, but only the most interesting can be mentioned.

Bones Facts

Number of bones

In newborns 300 bones and in an adult they become 206. The reason for the many bones in babies is the division of large bones into smaller ones that fuse with age (for example, the bones of the skull). Nature created this for newborns who need "elasticity" to be born.

Besides:

• The skeleton contains 34 unpaired bones.
• The bones of the skull consist of 23 units.
• vertebral column consists of 26 bones.
• The ribs and sternum are made up of 25 bones.
• Skeleton upper limbs consists of 64 bones.
• Skeleton lower extremities consists of 62 bones.

Change in human height

We are higher in the morning than in the evening by 1 cm.

The cartilage between our bones at the beginning of the day in a unclenched position. However, during the work day, we sit, walk, or do something else, which leads to compression of the cartilage at the end of the day.

For example, in astronauts, the change in height is even more interesting. With a long stay in weightlessness, their growth increases by 5-8 cm.

The danger of such a change in growth lies in the fact that the strength of the spine decreases. Growth gradually returns to its previous parameters when the astronauts return to Earth.

After the death of a person, his height increases by about by 5 cm compared to his height in life.

Facts about teeth

The tooth is the only part human body, which does not recover itself. If you've ever lost a tooth, you probably know how frustrating it can be. After the outer shell (enamel) is damaged, you will soon go to the dentist.

Interesting Facts:

• Tooth enamel is the most hard tissue, which can be produced by the body.
• Even considering that calcium is necessary, including for bone tissue, 99% calcium is in the teeth.
• Some studies prove that 2,500 years ago the Mayan people (men) decorated their teeth with precious and semi-precious metals and stones. By this they showed the strength of their individual.

Bone strength

Human bone is stronger some types of steel and 5 times stronger reinforced concrete. However, this does not mean that your bones cannot break.

Bones also have a very high resistance to compression and fracture.

In older people, the number of minerals in the bones, causing the bones to become brittle (osteoporosis).

Muscle Facts

Facts about language

The strongest muscle in human body- language. This means that the tongue is the strongest muscle in relation to its size.

Considering daily food intake and spoken language, it can be argued that the language becomes stronger every day.

Since the tongue has extreme mobility (per minute about 80 movements), it can soak and chew food, clean teeth with particles of solid food, mix saliva with food, and push food that has already been chewed up the esophagus.

Without language, we would not be able to speak.

Bones are the foundation of the foundations - protection internal organs, the skeleton of the whole organism, the ability to move and live full life. But how much do you know about bones?

The carp is considered the record holder for the number of bones, because its skeleton consists of 4,386 bones. A very curious comparison: the human skeleton, for example, consists of only 212 bones, along with 32 teeth.

There is a real Logan Wolverine in the world, the one made of adamantium - this is a frog from Africa Trichobatrachus robustus - at the moment of danger, its bones in the paws break out, piercing the skin in the manner of a cat.
How the bones are pulled inward by scientists has not yet been fully elucidated. They believe that the frog has excellent regeneration and the wounds simply overgrow, like the bones.

Large mammals such as horse, elephant, giraffe sleep standing up. This is due to evolution, in order to immediately start running in the event of an attack.
And for this, in the knee joint of these animals there is a special "lock" that is "locked" during sleep and does not allow the animal to fall. By the way, flamingos also have such a "castle".

Do you know how the Eiffel Tower was built?
The design of the Eiffel Tower was based on the research of Professor Hermann von Mayer. Professor researched bone structure the head of the femur where it curves and angles into the joint. The head of the bone is covered with a covered network of miniature bones with a strict geometric structure; it does not break under the weight of the body, since these bones redistribute the load.

In the human body, there is a constant renewal of organs, including bones. Every 7 years, our bones undergo a complete renewal of bones.

Human bones are very strong. A bone block the size of a matchbox can support a weight of 9 tons. The most strong bone in the human body, despite the fact that it is hollow - tibial.

True, there is an exception in the human body - the ribs are considered the most fragile, because they can break even from a medium-strength blow.

By the way - you know what femur able to grow in breadth under the increasing weight of a person. That's why fat people often the legs are located in the so-called "x"

Children are born without kneecaps. Only by the age of 3, the cartilages located instead of future cups ossify

By the way - the patella - the most traumatized bone part of a person - annually there are about 1.5 million calls for problems with the patella.

shark has no bone skeleton. Her skeleton is solid cartilage (flexible bones). It is noteworthy that in order to be crushed on land, a shark needs only its weight. own body

But in garfish fish, the bones are green due to the high content of biliverdin

The largest bone known to man- top bone blue whale. The art of bone carving is called scrimshaw.

The dinosaur bones you see in museums aren't really bones.
Actually, these are stones - millions of years ago, the destroyed bone tissue left behind an organic sediment, which, under the influence of chemical processes, turned into a stone in the form of bones. Mineralized dinosaur bones are called dinobone and are valuable in the jewelry world.

All bones in the human body are interconnected, except for one - the hyoid

The question of how horses sleep arises due to the fact that the animal can very often be found standing with its eyes closed and its hind leg tucked in. People who have had little contact with horses often jump to the conclusion that these elegant animals sleep standing upright. The animal does not react to anything, except that the tail and ears sometimes twitch. Therefore, it seems that this is his typical form of sleep. This is true, but not quite. Technically speaking, horses sleep standing up, but given state is rather half asleep.
Thanks to special structure knee joints(if necessary, they can be blocked, fixing the ligaments and bones), the animal can evenly distribute the body weight between the four legs, almost not feeling its heaviness during muscle relaxation. In this state, with a slightly arched lower back, lowered head, tail and slightly drooping lower lip, the animals doze off. But it’s hard to call it deep sleep, because how a horse usually sleeps can vary.
Let's figure out why horses sleep standing up. The reason for this vertical slumber is the need to maintain security. The animal does not see protection in enclosures and other security measures taken by humans. Instinct tells him that it is necessary at the first danger to quickly break away and run, hiding, for example, from predators. And they are in the real world, in wild nature may appear at any time. And from such a slumber the animal can come out almost instantly. If the horse slept horizontally, it would take some time to get up and wake up completely, and these seconds could be fatal. This is why it is beneficial for horses to sleep standing up most of the time.
But that doesn't mean you don't need to sleep on your side. On the contrary, only he is full-fledged for this creature, while standing the horse rather simply rests, restores its strength. The best way make sure you are safe and lie down. It is believed that otherwise the phase of deep sleep cannot be reached, which means that if the animal does not lie down, then it simply risks not getting enough sleep. It's hard to run away from a predator when you're sleepy. Therefore, horses sleep lying down only when they are confident in safety, and it is quite difficult to make sure of this, especially if there is no herd of relatives around who can warn of danger in case of its occurrence.
Consider how long horses sleep. The duration of their sleep is very different from human. From four to fifteen hours sleep occurs in a standing position. Lying down, horses can rest from several minutes to a couple of hours, and the real recovery of strength occurs mainly in the supine position, which is why it is a priority. It is interesting that the drowsiness of these animals is sensitive, even if the horse naps while standing for fifteen hours in a row, this interval is still divided into small fragments of drowsiness for several minutes. Therefore, when the horses doze while standing, it is extremely easy for them to wake up, they can quickly respond to any changed situation.

Bogatyr Dmitry Khaladzhi constantly surprises with new records. He is moved by multi-ton cars, he easily bends horseshoes and nails, lifts unimaginable weights. How such huge loads affect his body. We asked Dmitry this question during an online conference.

You have such dangerous tricks. Do you get tested often? How do these huge physical loads affect your body?

The last time I was examined was a little over a year ago at Moscow Hospital No. 63. This is a hospital where members of the Russian Olympic team and cosmonauts are examined and treated. This took place as part of the shooting of the film. They shot a documentary about phenomenal people and I was offered to be examined there. Still, we decided to get to the bottom of what is the reason for performing certain power numbers, why I stay alive, why I don’t break down, etc. There I was examined completely: heart, liver, kidneys. The survey showed that everything is working normally. Examined the composition of adipose tissue, general analysis blood, doping test, bone index. By the way, there was an interesting moment: when they examined the bones, it turned out that the level of my boneiness (I’m not saying this medical terms), my boneiness index is higher than the existing table. I think that in preparation for certain strength tricks, not only muscles, tendons, but also bones are trained. Our bone is porous, but at large physical activity(for example, in those people who are engaged in interrupting objects with the edge of the palm), these pores are filled with bone tissue and the bone becomes much stronger and heavier. Those. Something similar happened and is happening to me.

The weather is so bad now… Do you suffer from SARS? What are you treating?

The last time I was ill and lay with a temperature in childhood. I think that people get sick a lot because they have a weakened immune system. People have become susceptible to all kinds of SARS. Nobody knows how old AIDS is. But people didn’t get sick with it before, maybe for the reason that they had such strong immunity that he just didn't hit them. If people used to be engaged in heavy physical labor without exception ... Even 100 years ago, for example, a peasant, when plowing the land, every day during the plowing period, walked up to 35 miles behind the plow. Imagine what a colossal load a person received. And then when he mowed, he also had to walk the same number of miles, only with a scythe. Those. people were physically very hardened. And so they didn't get sick. There were no such a huge number of influenza strains, a person simply coped with them with his own immunity. I could advise everyone modern people temper. It is not necessary to dive into the hole, it is not necessary to pour cold water. Just do not wrap up to the very eyes, but dress a little lighter to get used to the cold. I am a regular herbalist. I constantly drink some herbs throughout the year, which helps the body. Not medically, but naturally traditional medicine. It is not some kind of witchcraft or witchcraft. modern medicine it quite accepts.

Do you know about herbs or do you consult someone?

I understand myself. There are people with whom I consult. But what exactly is necessary for me for everyday life, I understand herbs.
