A combination of two-dimensional (2D) and three-dimensional (3D) analyses of tissue volume ultrastructure acquired by serial block face scanning electron microscopy can greatly shorten the time required to obtain quantitative information from big data sets that contain many billions of voxels. Thus, to analyse the number of organelles of a specific type, or(More)
This investigation of the vestibular apparatus of rats exposed for 20 days to weightlessness on board an earth satellite and to acceleration during take-off and landing has revealed a set of changes in the structural and functional organization, such as adjoinment of the otolith to the utricle receptor surface and peripheral localization of the nucleoli(More)
Basic variants of the evolutionary program of formation of simple sensory systems-structural models of gravitation receptor, organ of sight, chemoreceptor organ as well as of the nervous system at early stages of the Metazoan phylogenesis—are considered using results of our own morphofunctional studies and of literature data.
In oral epithelium of adult jelly-fish Beroë cucumis, the main stages of differentiation of chemoreceptor cells replacing damaged degenerating chemoreceptors are described. The initial stages are connected with transformation of the so-called precursor cells that on transformation into juvenile cells, are inserted from mesoglea into basal epithelial areas.(More)
In the electron microscopic study of oral epithelium and underlying areas of mesoglea of adult comb-bearers Berë cucumis (Ctenophora), there were described peculiar light cells with a characteristic localization, ultrastructure, ways of interaction with cells of other types including developing and mature chemoreceptors and neuronal processes. Comparison of(More)
Electron microscopic and cytochemical studies of the synapses of the gravity receptors in Coelenterata, Ctenophora, Annelids and Molluscs has shown the mediators both of cholinergic and adrenergic systems. As a rule, the two mediatros were connected with different receptor systems (Ctenophora) or with the synaptic structures of various parts of the chain:(More)
Result of the performed electron microscopy cytochemical study was an indirect detection of intracellular localization of inositol 1,4,5-triphosphate according to sites of its binding with specific phosphatase in receptor and secretory cells of epithelium surrounding actinostome of the comb jelly Beroe cucumis. The highest level of the deposit of the(More)
