Development of the Batrachian Egg

Producer: SFRS (Service du Film de Recherche Scientifique)

This film presents a study made on triton (Triturus alpestris). After having seen the segmentation of the egg, one sees the gastrulation movements and the formation of the yolk. A schematic representation of a gastrula opened sagitally, then transversally, allows students to follow the development of the blastodermic layers up to neurulation. The last part of this film shows the neurulation and the modelling of embryo, with the formation of the branchiae and the lower limbs.
