title: [Morphometric and histochemical characteristics of the frog sartorius muscle in ontogeny].
abstract: Morphometric and histochemical investigation of musculus sartorius was performed in ontogenesis in Rana ridibunda and Rana temporaria. Muscular composition was characterized according to the type of muscular fibres. Spectrum of lactatdehydrogenase isoenzymes was studied at different developmental stages. As the studies demonstrated, musculus sartorius underwent some essential changes in ontogenesis which manifested themselves in increasing number of muscular fibres and their areas, in changing LDG isoenzymic spectrum. Differentiation of the muscular fibres three types takes place at the 30th stage after P. V. Terentiev and depends on the nerve system maturation.
