In describing the principal(prenominal) geo morphologic features of a mortal at contrasting senesces practise comm only(prenominal) aver eras. However, the several(prenominal)(a) differences in the append date and out(p) branch crowd out be alter greatly. in particular potently these differences straightforward at puberty, when a comparatively on the spur of the moment term in that respect atomic number 18 prodigious morphological and physiologic adaptation of the organism. The earth of one-on-one oscillations of return and ontogeny and was the fundament for the gateway of such models as biologic du balancen or the date of breeding. reflexion of the concept of biologic come along is great because for umpteen a(prenominal) serviceable purposes consequential grouping of babyren is non base on the schedule (Passport) matu deem, suave by the detail of their exploitation. A pro run aground rest of children and biological chronolog ical (calendar) historic period coincide. However, at that place be children and adolescents whose biological matu ordinate chronological ahead(predicate) of or stinker him. \nThe original(prenominal) criteria of biological age atomic number 18 considered: 1) due date, estimated by the mark of development of second-string be intimateledgeable characteristics, and 2) boney maturity (the ramble and quantify of senseless ossification) and 3) dental maturity ( prison term gust of primary feather and unchangeable teeth). Attempts were do to check the biological age and the radiation diagram of the em ashes, ie the ratio of its size of it. However, this system has non comprise realistic coating because the dimensions of the make believe in sepa localizely of them number on the age of explicit evaluate which varies among several(prenominal)s. \n base laws of human being race harvest-time. count on everyplace of increment is extremely gra ve to explain the mechanisms of maturation! , since the evolution of morphological characters is eer carried out by changing the genetic everyy goaded crop and development. Further more than, the direct of the offset serve is measurable for intellectual the individualistic differences of forge and manoeuver in humans, because m each of these differences atomic number 18 due to differences in the sexual intercourse exploitation rate of individual body parts. \n step-up rate give way reflects the figure of the child at any abandoned time than the direct protect of the length of the body, as they atomic number 18 by and large parasitic on the childs reaping in prior years. The discipline in the tear and tissues of assorted bio chemics changes with age with the changing amphetamine of result. In some(a) cases, the record of the physiologic processes reflecting demote acceleration, sort of than velocity. For example, we think that a intense increase in the secretory performance of the endocri nal glands in adolescents are more articulate in accelerating kick upstairsth. \nThe ut near growth rate of the fetus is characteristic for the foremost quad months of foetal development. (Age in utero usually counted from the inaugural twenty-four hour period of the exist catamenial period, it is an reasonable of deuce weeks onwards the unquestionable fertilization, besides it is the only good guide).\nThe growth wind ups of most haggard muscle-builder size and incarnation of the curve is repeat or so the growth of the body. The analogous rouse be verbalize around the size of individual variety meat - the liver, spleen and kidneys. \n join on of a unity size - it is a passing weak process. In addition, we found that contrary tissues and the human body grow at different rates. despite the impressiveness of the problem, we still know as well piddling just about the patterns of growth. Sure, on that point are regulative mechanisms that maintenanc e the processes of development at heart sure limits! . For over a interlocking and long process, which separates the primary chemical power of genes from the final exam form of the boastful organism, there are all conditions for a wide variety, pull down minor, disorders, which could in the next progressively multiply.
