[Structural models of simple sense organs by the example of first metazoans].
Basic variants of the evolutional program for formation of simple sensor system--structural models of gravitation receptor, organ of vision, chemoreceptor organ as well as of the nervous system at early stages of the metazoan phylogenesis--are considered from results of our own morphofunctional studies and literature data.
