Advice 1: Why do people have different weight bones

Bones are the only solid material in the human body and its strength close to steel but their weight three times lighter. If people had bones of steel, they would weigh about 180-240 kg. an Interesting phenomenon is the fact that the bones of each person are different weight, which is associated with several factors.

The weight of the bones



In the body of a newborn baby present 350 soft and flexible bones that grow together and in the end, the skeleton adult human consists 206 bones solid. In living bone contains 50% of water, and 15.7% fat, 21.8% of inorganic substances and 12.5% organic matter. In fact, bones are composed of minerals – namely, calcium, magnesium, phosphorus, copper, zinc, barium, aluminum, fluorine, silicon, and so on. The density of all bones is the same, however some people have a fine-boned skeleton with thin fingers, small feet and hands, and narrow shoulders and narrow chest. These people bone, respectively, weigh less than the big-boned people.

The weight of bone does not affect the weight of the human body – just the width of the bone depends on the size of the attached muscle, which weighs more than fat.

To determine the fineness or broad bones, you can use a simple test is sufficient to measure the circumference of your wrist. If it is less than 16 inches, the bone is thin, if it is 16-19 inches – the bone is normal, but if more than 19 centimeters – boned. While the muscles and bones soaked in liquids that gives them the difference between the weight of a person. In addition, the weight of the bones may depend on body type, which happens to be asthenic, normosthenic and hypersthenic.

The decrease in bone weight



Weight and bone density can decline with age because of the skeleton washed out minerals and calcium. The result is bones become fragile, porous and light, which significantly increases the risk of fractures and diseases such an insidious disease such as osteoporosis. This is especially true of fine-boned people, and especially blondes, at risk of this disease.

Depending on the growth of the skeleton the average human adult has a specific gravity of from 7 to 10 pounds.

To avoid age-related weakening of bones, should be consumed a large amount of dairy products and regular exercise body because exercise strengthens the skeleton of the best of all calcium supplements. It should be remembered that the reduced weight of the bones is not always associated with osteoporosis – it can be affected by various genetic diseases, improper or unbalanced diet, and even congenital defective part of bone mass.

Advice 2: As fused bones

The fractures in most cases, especially in children, are fused without deformation. In connection with the deterioration of blood circulation in the body with age, due to the improper actions of the doctor bone fractures can heal properly.

Instruction
1
The fracture begins to heal almost immediately after the incident. From injury to full fusion of bone goes through four stages. The first stage is the formation of so-called clot. Blood is a viscous mass, which is collected at the ends of broken bones. Of these clots formed fiber will contribute to the coalescence of the bones, like adhesive.
2
In the second stage of healing a fracture cells clot "treat" the injured surface. Smooths sharp and jagged edges of the bones, fill the cracks in them and connect the two ends of the broken bone together.
3
The third stage is characterized by the formation of callus. Happening this moment at the seventh (or slightly longer) day after injury. At this time, formed at the fracture site as a result of callus cells remains stationary due to the cast. Otherwise (without gypsum) because of its brittleness it can crack, break again. Over time, this callus will zacatepec and turn into solid.
4
And final stage of the splice, the fracture occurs in a long time. From three to ten weeks the patient will have to wear at the site of fracture in a cast. At this time, via the blood vessels to the point of fracture, to the corn, will deliver the required splice material. Including calcium, without which rapid coalescence of the fracture will not happen.
5
At the last stage of healing of the injury there is a complete ossification of the fracture. The bone in this place getting sturdy, durable. The cast, the doctor will remove it, but will warn that this place should be protected even during the year, the fabric is completely healed and the bones have become strong as before the fracture.
6
Open fractures have caused physicians is much more fear than closed. The fact is that with an open fracture there is a risk of inclusion in the internal tissues of microbes, bacteria that can cause diseases that are difficult to treat. For example, osteomyelitis. In a closed fracture there is no such problem.
Useful advice
While wearing the plaster should take medicines containing calcium, eat foods rich in this mineral and vitamins A, E and D. In this case, fracture healing will go at a heightened pace.

Advice 3: How many bones in the human body

The human skeleton – a kind of frame, consisting of numerous bones of various shapes and sizes, thanks to which man can bend and straighten your body to make the most various movements of the hands and feet and, of course, to walk, to sit, to dance and to perform other complex manipulations. And wondered whether you ever have a question: "How many bones in the human body?".

The difference in the number of bones in adult and child



Despite its hollow structure and porous structure, bones are the hardest material in the human body. Daily human bones are subjected to tremendous loads that do not affect its main features. Strength they can be safely compared with steel, but that's the bones weigh three times less. However such properties has only the skeleton of an adult. The bones of children are soft, flexible and elastic, and the bones of elderly people is fragile and brittle.

The exact number of bones in the human body can't even the experts. According to their observations, the skeleton adult human consists of 206-208 bones, while the skeleton of a newborn baby may include about 350 bones. It turns out that the maturation of the man some of his bones. Hence, such a significant difference in their number of adult and child. The process of connecting a honey of certain bones in the human body ends only to 22-25 years, with the last one fused collarbone. Based on this, we can conclude that the number of bones in the young man and old alike.

Not to mention that the number of bones in the human body is influenced by the individual characteristics of the structure of the skeleton, as well as various deviations in the formation of the spine. Such defects include the presence in the human body excess edges, observed primarily in boys, the extra fingers on the hands and feet, extra bones in the feet.

Interesting facts about human bones



Despite the fact that the number of bones in the body of a baby exceeds their number in an adult almost twice, some of the bones of newborn babies are simply not available. This applies, first and foremost, kneecaps. The formation of these essential components of the human skeleton occurs in children only to three-year age.

The smallest bone in the human body is located in the middle ear, the stapes, and the largest is approximately one third of the total growth of the human femur.

The coccyx is a whole group of 3-5 vertebrae fused together in the process of a growing person.

Many people think that teeth are a part of the human skeleton. In fact, these elements of the human body to the bones are irrelevant.
