title: Onto-phylogenetic aspect of myotomal myogenesis in Chordata.
abstract: This paper presents an onto- and phylogenetic aspect of myotoamal myogenesis in Chordata. A comparative analysis of early stages of myotomal myogenesis in Chordata indicates that the myogenic process in this phylum underwent evolutionary changes. The first stage of the process is myogenesis leading to development of mononucleate mature muscle cells, the most advanced stage is formation of multinucleate muscle fibres.
