Evolutionary bases of morphogenesis

Comparative anatomy allows us to understand the organization of formation and to substantiate the mechanisms of human organogenesis. The basis of the mechanics of the development of organs is uneven growth, topographic coordination and their changes. Interorgan interactions in embryogenesis determine the formation of anatomical and topographic relationships of organs and walls of the body cavities (limiting capacity factor). The ratio of growth rates of organs determines the influence of this body on the development of neighbouring organs and their reverse effect, depending on the ratio of their size. Inter-tissue interactions type epitelialnyh underlie organogenesis. Its main mechanism of multifocal growth of the embryo: proliferating epithelial buds of adjacent organs alternate with intermediate areas of the mesenchyme, which taper between separated anlages of organs. In evolution, probably, the functional activity of organs under overload determines their adequate morphogenesis by changing the absolute and relative growth. Morphogenesis occurs in the evolutionary chain of ontogeny based on the conjugation of structure and function, through different forms of interactions. The results showed the dependence of the structure of animals on the type of their food (a vivid example - the cecum of rodents, omnivores and herbivores) and mobility (the cecum of degu and guinea pig).
