Is Connected. Moreover, In There Are The Departments

is connected. Moreover, in there are the departments having a direct bearing on vegetative nervous system as a whole. Unlike the central nervous system the vegetative nervous system regulates activity of an internal, or, more precisely, supervises repeating, automatic processes in a body. The vegetative system consists as though of two parts - sympathetic and parasympathetic which render opposite influences on fabrics and bodies. So, for example, if excitation of sympathetic department leads to increase of arterial (blood) pressure, excitation parasympathetic - to its fall. Thus, these two contradictory and co-operating departments of nervous system by double maintenance of effect stabilise size of a deviation of all those processes which are regulated by vegetative nervous system in certain limits. Therefore at deep defeat in experiment at animals trophic frustration almost in all bodies with the hemorrhages caused by infringement of a food, an exchange and blood supply develop; there comes a dystrophy of muscular fibres etc.

Really, The Nature Simultaneously Also Is Surprisingly Uniform

Really, the nature simultaneously also is surprisingly uniform and amazingly various. The most simple live organisms - viruses - have the same structure, as well as carriers of a heredity at higher organisms - genes. Fibers at bacteria and at the person are constructed of the same building blocks - amino acids. How stability of its basic elements and their amazing improvement in the course of evolution on a way from the elementary monocelled to higher organisms is provided in the nature? Much depends on the answer to this question. Including a death solution. We have got used to consider that any life comes to the end with death that "to live - means to die" (Engels F.Dialektika of the nature). But what the death inevitable does? Before to consider this question, I will remind the reader: in the nature, as it is known, there are essentially various two mechanisms of death - from external and from the internal reasons. Theoretically some elementary unicells are immortal, as after each division similar beings arise two completely the identical affiliated descendant, possessing all properties of an initial organism.
