title: [Histochemical characteristics of the lingual salivary glands of several classes of vertebrates].
abstract: The obtained results show that secretory elements of the tongue integuments submerged to the depth of the organ. It was accompanied by a formation and complication of terminal portions of the glands and their secretory pathways. In the process of evolution there occurred a divergence in the development of glandular cells from mucous ones in fishes through mucoserous and seromucous cells of amphibia and reptiles to mucous, seromucous and protein cells in the tongue glands of higher mammals. In mucous glands of terranian vertebrates, especially in mammals, the number of components in the composition of the produced secretion was found to increase.
