All muscles of the person are formed by special fabric which fibers are fastened to the help of connecting fabric in bunches. All of them are penetrated by nerves and vessels. Reductions of muscles are caused not only their structure, but also their interaction with a skeleton of the person.The sponsor of placement P&G Articles on the subject "Why Muscles Are Reduced" How to gain weight without chemistry How to draw a back How to treat dislocation of a shoulder joint of the Muscle of the person are reduced, first of all, in view of various irritations. This process is followed by a thickening or shortening of muscle fibers, and, therefore, all muscle in general. How it is possible to cause this reduction?
For example, it is possible to carry out a short electric discharge to a body that will cause instant reduction of muscles. It will proceed no more than 0,1 seconds. Other way to cause reduction of muscles – to be throughout long time in a certain situation.
That is during lying on a bed or sitting behind the computer. In these cases long muscular contractions take place. All this is caused by position of a body at which practically there is no movement.
So, why muscles are reduced?
This process happens in a live organism under the influence of excitement which comes to muscles from nervous system on centrifugal nerves. It is possible to make two simple experiments visually to understand how it occurs.
For a start sit down on a chair and put one foot on another. Ask to hit you with edge of a palm on a knee. This action will cause irritation of receptors of a sinew of a knee. The excitement process which arose in them will be transmitted through a spinal cord on nerves in muscles of the person.
They will be reduced for some time that will lead to shin "podskakivaniye". This process is called still a knee reflex. It is caused by excitement which came from TsNS to skeletal muscles.
Second simple example of reduction of muscles. Call to any passing person down the street. You will see how it will turn the head in spite of the fact that you can not know it at all. And, it will turn exactly towards a sound. It is reflex process which is caused by nervous excitement. It gets into receptors of organs of hearing and goes through a brain to muscles of the person.
Thus also there is a reduction of muscles.
