Nazarchuk G. The histomorphology of spinal knots of vertebrate animals

Object of researching - the specific and age differences of spinal knots. Aim of researching - to find out a morphocytochemical architectonics of spinal knots of chest part of comparative anatomical series of Vertebrate animals and during post-natal period of ontogenesis. Methods of researching - anatomical, histological, neurohistological, histochemical, morphometrical, statistical. It's proved that the structural reconstruction of spinal knots during phylogenesis is characterized by lessening of compactness of neurons and neuroglias cells, by growing of neurons, by increasing the number of satellites cells, by complication of neurofibrous component of organ, by changing of dispersion DNA, by increasing of intensity of histochemical reactions for PNA contents in neuroplasm, by accumulation of total protein in nucleus and neuroplasm. The heterohrony of differentiation of histo- and cytostructures of spinal knots depend from phase of post-natal period of ontogenesis. Branch of using: the results of scientific researching are used in educational process and scientific-researching work of 22 structural subdivision of high educational and scientific researching institutes of Ukraine, Russian, Republic of Byelorussia and Respublic of Moldova. Branch of using: veterinary medicine.
