[Spatial deployments of morphogenetic movements as elements of the oral field in anuran amphibians. II. The structure of the oral field].
The structure of morphogenetic movements in the oral field of Anura was studied. The movement of any region of the oral field depends on several "elementary waves" of morphogenetic rearrangements, each of them being swept in space along the same cell layer. The waves of morphological rearrangements of cells from different layers are coupled with each other in a stable manner. The cells of the given layer are involved in their morphogenetic movements consecutively, whereas the morphogenetic movements of cells in the interrelated layers are developed in parallel. The waves of morphological rearrangements are those of contact polarization of the cells and, under certain conditions, are spread within several minutes.
