§ 15. Posture. Warning flat feet
What is posture and what are the reasons for its violation?
Why did the arches of the feet form and why are they deformed?
How can you determine the curvature of the spine and the presence (or absence) of flat feet?
Posture is the habitual position of the body when standing, sitting and walking.
There are three degrees of poor posture.
How to prevent spinal curvature? First of all, you need to sit correctly at the table (Fig. 38). If the table is too low, you have to lean over it, and if it is high, the person bends his torso so that the writing hand is on its surface. The first leads to stoop, the second leads to lateral curvature of the body. Asymmetrical muscle load can also lead to poor posture: for example, carrying weights only in the right hand, leaning more to one side than the other when doing physical exercises, etc.
Prevention and treatment of flat feet.
Posture, osteochondrosis, corrective gymnastics, stoop, lateral curvature (scoliosis), flat feet.
1. What happens when there is a violation of posture of the first, second and third degrees?
What disturbances in the functioning of internal organs occur with incorrect posture?
What is flatfoot, what are its causes and treatment principles?
Analyze: is your body position correct when reading, writing, or carrying heavy objects.
To identify a stoop (round back), use a measuring tape to measure the distance between the most distant points of the left and right shoulder, 3-5 cm down from the shoulder joint, from the chest and from the back. Divide the first result by the second. If the result is a number close to or greater than one, then there are no violations. Getting a number less than one indicates poor posture.

no, it is convenient to count time with the words “one second”, “two seconds”, etc., which approximately corresponds to the indicated time.
Preliminary remarks. The vessels of the nail bed include not only capillaries, but also tiny arteries called arterioles. To determine the speed of blood flow in these vessels, it is necessary to find out the length of the path - 5, which the blood will travel from the root of the nail to its top, and the time - t, which it will require for this. Then, using the formula V = S/t, we can find out the average speed of blood flow in the vessels of the nail bed.
Progress of experience. Let's measure the length of the nail from the base to the top, excluding the transparent part of the nail, which is usually cut off: there are no vessels under it. Let's determine the time it takes for blood to cover this distance. To do this, use your index finger to press the nail plate of your thumb so that it turns white. In this case, the blood will be forced out of the vessels of the nail bed. Now you can find out the time of blood filling of the vessels. We release the compressed thumbnail and measure the time it takes for it to turn red. This moment will tell us the time during which the blood has made its way to the end. After this, we calculate the blood flow speed using the formula. Compare the data obtained with the speed of blood flow in the aorta. Explain the difference.
Please do this laboratory work! Thank you.

Equipment: measuring tape.
To identify a stoop (round back), use a measuring tape to measure the distance between the most distant points of the left and right shoulder, 3-5 cm down from the shoulder joint, from the chest and from the back. Divide the first result by the second. If the result is a number close to or greater than one, then there are no violations. Getting a number less than one indicates poor posture. Stand with your back to the wall so that your heels, shins, pelvis and shoulder blades touch the wall. Try sticking your fist between the wall and your lower back. If it goes away, there is a violation of posture. If only the palm passes through, the posture is normal.
Equipment: a bowl of water, a sheet of paper, a felt-tip pen or a simple pencil.
Stand on a piece of paper with your wet foot. Trace the contours of the trace with a felt-tip pen or a simple pencil.
Posture and flat feetI. Detection of postural disorders.
Find the center of the heel and the center of the third toe. Connect the two points found with a straight line. If in the narrow part the footprint does not go beyond the line, there is no flatfoot
II. Detection of flat feet (work done at home).
Find the center of the heel and the center of the third toe. Connect the two points found with a straight line. If in the narrow part the footprint does not go beyond the line, there is no flat foot (Fig. 39).
Goal : learn to identify postural disorders in a simple way.
Equipment : flat vertical surface (wall without baseboard).
Stand with your back to the wall (or to any vertical surface) so that your head, shoulders, buttocks, and heels touch the wall.
Try to stick your fist between your lower back and the wall without disturbing your body position. If this is not possible, try to stick your palm through.
Analysis of results. Posture is considered normal if a palm passes between the lower back and the wall. If a fist passes between the lower back and the wall, the posture is impaired. To identify a specific type of postural disorder, it is necessary to use a complex technique.
Goal : master a simple way to identify flat feet.
Equipment : sheet of paper, water or cream, pencil or paint, ruler, protractor.
With a wet or creamed foot, stand on a sheet of paper. Trace the print with a pencil or paint over it.
Connect the tangent mark from the metatarsus with the mark from the heel (Fig. 1, line AK).
Find the midpoint of AK, a point equidistant from the points of contact.
Draw two segments perpendicular to AK, restoring them at the point of tangency A and at the midpoint M.
Measure segments AB and CD. Point C lies in the place where the MD line intersects the footprint in the middle part. For some, the SD segment may be equal to 0.
Determine the percentage ratio of DM:AV and compare your results with the following standards. The ratio (SD/AV)x100% should not exceed 33%. Higher results indicate flat feet.
Your data: right leg (SD/AB)x100% = ( ___ / ___ )x100% = ___ left leg (SD/AB)x100% = ( ___ / ___ )x100% = ___
Rice. 1 . Determining the presence of flat feet
Goal: to determine the relationship between the processes of excitation and inhibition.
Equipment: stopwatch, subject.
The subject, sitting with his eyes closed, at the experimenter's command, begins to count three minutes (180 seconds) to himself. The experimenter records time using a stopwatch.
Once 180 seconds have elapsed, the subject opens his eyes. The experimenter marks the true time using a stopwatch.
Draw a conclusion about the relationship between the processes of excitation and inhibition in the subject at a given point in time, taking into account that:
if the subject’s time turns out to be less than the true one, then excitation processes predominate in him at a given moment in time;
if the subject’s time turned out to be greater than the true one, then inhibition processes predominate in him at a given moment in time;
if the subject’s time turned out to be approximately equal to the true one, then at that moment in time his processes of excitation and inhibition are balanced.
Conclusion. Organelles, like the organs of a whole organism, perform a specific function. Modern research tools have allowed biologists to establish that, according to the structure of the cell, all living things should be divided into “non-nuclear” and “nuclear” organisms - eukaryotes. The group of prokaryotes includes all bacteria and blue-greens (cyanes), and the group of eukaryotes includes fungi, plants and animals. The commonality of the chemical composition and structure of the cell - the main structural and functional unit of organisms - indicates the unity of origin of all life on Earth. 31.
