What causes flat feet?

The next time you step out of the bath or shower, pay attention to the trail your wet foot leaves. If the footprint is clearly marked, your foot is normal. If your footprint has a sole mark, since the entire sole touches the floor, you have flat feet. The leg is tricycle because it stands on three points. Because of these three supports, the foot has the shape of an arch. This arch is not hard, but elastic and resilient, thanks to the arrangement of bones, cartilage, ligaments, tendons and muscles of the foot.

Indeed, from an "engineering" point of view, an elastic arch is the best type of structure for a weight-supporting structure. The space under the arch of the foot is filled with adipose tissue. Blood vessels, nerves, tendons of the fingers pass through this adipose tissue, which do not experience compression during walking.

When a person goes outside, he may never have foot problems. The reason for this is that the irregularity and "elasticity" of gravity changes the position of the foot with each step. Therefore, the entire foot, including the sensitive muscles and ligaments of the arch of the foot, is always active, that is, all parts of the foot are constantly exercised. When we walk on even city streets or hard floors, only a few points of the foot are constantly stimulated.

The foot adapts to this special stimulation. She really remains in a state of "spastic tension". This condition of the foot disrupts the processes at all its points, their nutrition and work.

Certain tissues where there is little circulation of blood become lethargic, anemic and weak. Then the arch of the foot becomes unable to support the weight of the body and drops down. The result is flat feet! Of course, in some cases, the cause of flat feet is that certain people are born with natural tissue weakness. In this case - with a weak arch of the foot.

Random interesting fact from the Great Encyclopedia:

What is smell?

Everyone loves pleasant smells - the scent of flowers or the smell of a freshly baked cake. But there are also very unpleasant odors. Oddly enough, but the amount of a pleasant or unpleasant smell, in order to recognize it, can be very, very small!

Do you know that we can detect the smell of a certain substance if only 1/30 of it is present in a given volume of air? And this is characteristic of the average man, whose sense of smell is incomparably worse than that of dogs! How do we perceive smell?

We recognize an odor when a chemical comes into contact with certain nerve endings. These substances can be gaseous or solid. This is why we can smell things from a distance. The olfactory receptor nerve cells are located on the hairs that cover the nasal mucosa. These nerve endings cover a small space at the top of the nasal cavity. They are arranged in such a way that the air drawn in during breathing passes through them. But if we specifically want to smell something, such as flowers, then we inhale the air through our nose. When a substance enters the olfactory zone, the first impulse occurs, which is transmitted to the brain, where the odor is assessed.

There are 5 types of smells that we can recognize: floral (roses, violets, etc.) specific (lemon, apples, etc.) burnt (coffee, etc.) rotten (rotten eggs, cheese, etc.) etc.) and ethereal (gasoline, alcohol, etc.). We often confuse smell and taste because the gaseous particles of the food we eat irritate the olfactory receptors.

For example, if we drink coffee and do not smell it, then we will not feel its usual taste. This is why food seems tasteless when it is cold. Your sense of smell is blocked due to the cold, and this creates the effect of a lack of taste.

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

OLED microdisplay with record-breaking pixel density 30.01.2012

MicroOLED has unveiled a 0,61-inch OLED display with a resolution of 5,4MP. According to the company, this product is characterized by a record pixel density. The novelty is intended for use in camera viewfinders, night vision devices and in other cases where high quality of the screen perceived from a short distance is required.

The screen sub-pixel dimensions are 4,7 x 4,7 microns. MicroOLED specialists have managed to create a screen structure without gaps between pixels, which has made it possible to obtain twice the density of similar products available on the market.

The display is characterized by a contrast ratio of 100000:1 and a high uniformity of illumination. Display power consumption - 0,2 W. The device is capable of displaying 16 million colors, but a monochrome version is also available.
