[The histogenetic characteristics of the epithelial tissues of the mucosa of the pharyngeal and oral surfaces of the soft palate in ontogeny and under experimental conditions].

Processes of the development and growth of the soft palate mucosas in ontogenesis and also proliferation, growth and differentiation of epithelial structures were studied in the experiment. The epithelium of the soft palate nasal surface was established to be more labile and to be characterized with polymorphism forming single-layer and pseudostratified structures. Under these conditions the oral surface epithelium keeps stratified structures firmly. On the basis of discovered differences of the epithelium biological qualities a suggestion is made on the different genetic origin of epithelial tissues of mucosas of the soft palate oral and pharyngeal surfaces.
