The Most Widespread View On An Origin Of

The most widespread view on an origin of the limit limiting life expectancy, is the theory of "cellular death". It is known that in culture of a fabric, that is out of an organism, some cages of a fruit of the person are capable to share 50+10 time, and then perish. If cages to take from the person more advanced age or from persons with presenilation the number of the divisions previous �destruction of a cage proportionally decreases. On the basis of this data began fashionable to consider that the hours measuring time of a life, are concluded in each cage. It is supposed that the �destruction of cages or easing of functions in those cages which do not share after the development termination, finally leads to easing and �destruction of the organism. Thus, natural death often consider as an illustration to this construction. But there is an essential supervision which does not keep within at all these frameworks. The American scientists O.Robertson and B.Vexler (1962) have removed sexual glands at several copies related to a humpback salmon of a fresh-water kind of fish and contained then them in special tanks.

It Also Prevents Premature Puberty, Its Rates Are

It also prevents premature puberty, its rates are commensurated with the general development of a body. The essence of the mechanism of age inclusion of reproductive function consists in increase of a threshold of sensitivity to braking action of sexual hormones. Thanks to this increase it is gradually released from the braking which are carried out by sexual hormones on the mechanism of a negative feedback. As a result activity , and then and a hypophysis which, in turn, stimulates with the hormones sexual glands gradually increases. However increase in blood of concentration of sexual hormones does not conduct in this situation to activity decrease : thanking all to proceeding increase of a threshold of sensitivity again and again it is released from braking influence of sexual hormones. So capacity of reproductive system increases and at the same time the mechanism of self-control peculiar to system remains. Thus, along with the mechanism which is directed on balance and constancy (homeostasis) maintenance to each given moment, there is a mechanism which provides homeostasis infringement in time and by that carries out performance of the program of times an organism.

However Thus Would Lose As Regulation Body Much.

However thus would lose as regulation body much. For influence on the processes proceeding in a body, enough considerable quantity of hormones is necessary. Therefore should spend many forces for manufacture of hormones and according to them would remain for regulation less. Action hormones, in essence, represents continuation of nervous influence, and these hormones have on a hypophysis such regulating an effect. Absence at of some working functions allows it after a signal transmission on a hypophysis to be released for perception of the new signals arriving from external and private world. So, at first sight burdensome duplication of similar functions in and a hypophysis actually creates optimum conditions for regulation realisation. , thus, is the fourth level of regulation in an organism (sm, fig. 1). The fifth level of regulation - the central nervous system including and a cerebral cortex. Continuous changes of an environment demand the constant adaptation to them of body functions.

Metabolic Promotes Cancer Development. Stress, A Mental Overstrain

Metabolic promotes cancer development. Stress, a mental overstrain also it is long the detained negative emotions cause hypertensive illness, mental depression and accelerate a cancer current. All it so. But at the same time remains doubtless: though elimination of adverse external factors can increase longevity, it cannot expand its specific limit. In what here has put? Why ageing is combined with certain group of illnesses, instead of with any illnesses from many hundreds known pathological processes? Than the specific limit of a life - physiological ageing, that is wear process, the organism exhaustion, connected with the termination of updating of its cages, or certain illnesses which arise under the influence of the internal reasons is defined? And if truly last, what it for the internal reasons which operate with such law? In wildlife there are examples of the mechanism of the death which obviously have been not connected with influence of the external reasons. For all the kind of death peculiar to the butterfly is known.

) Here It Is Necessary To Note One Very

) Here it is necessary to note one very important circumstance again. Fibers are structural and functional elements of cages. Therefore transfer of cellular fibers in sugar is very unprofitable for an organism. Hence, if it is necessary to burn difficult fibers with their numerous properties as simple fuel it is better to take these fibers from such fabrics which are quickly updated in an organism and which, the main thing, do not bear certain structural function so time reduction of weight of this fabric will appear not so damaging. Such fabric are , dispersed in lymphatic glands and in others fabrics - a spleen, a marrow and, at last, as it was found out recently, - a principal organ of cellular immunity. Many know that after strong and long excitement it is easy to be ill - virus disease. It would Seem, what the general between excitement and propensity to an infection? This interrelation is generated by use for maintenance of energy needs of an organism in stress ( . 11). But at the height of stress all these possible consequences in calculation are not accepted.

). Artificial Infringement Of System Of Adaptation Involves The

). Artificial infringement of system of adaptation involves the serious consequences. So if to remove at an animal adrenal glands - gland, without which reaction cannot be carried out to keep his life even in leaving and food perfect conditions it is possible, only constantly entering hormones of adrenal glands. But as soon as there is a situation, the dose of these hormones should be sharply increased, differently the animal will be lost because of insufficiency of system of protection. And still the organism quite often pays dearly for the ability to be protected by the adaptation. The big group of illnesses, so-called illnesses of adaptation, arises in the conditions of stress. Why? Let's consider a classical example of a meeting of a cat with a dog, analysed with the physiological point of view still Uolterom Kennonom - the founder of the doctrine about a homeostasis. We will add this example with the description reactions in the spirit of Hans Sele, but we will include here some additional details which have been found out by numerous researchers of stress in further, after basic works of Hans Sele.
