The Example Is Especially Convincing That, On The

The example is especially convincing that, on the one hand, puberty should be somehow detained till that time while development and body growth will end, and with another - puberty possesses the evident lines characterising increase of capacity of reproductive system. If to recollect the general principle of work self-regulated systems, it is easy to understand that puberty cannot be caused primary strengthening of capacity working glands - sexual gland. Otherwise the increase in production of sexual hormones completely would brake regulator-gipotalamusa activity according to the mechanism of a negative feedback. It would eliminate possibility and regulations and developments. Hence, the puberty mechanism should be connected with changes of a condition of the regulator, that is . So it also is. In a number of researches it has been shown that the sensitivity threshold changes during all life. Soon after a birth possesses the maximum sensitivity to braking action of sexual hormones. Therefore the sexual centre during this period is braked by that small amount of sexual hormones which are already developed by an unripe organism.
