title: [Ultrastructure aspects of myoseptum formation in embryos of the common toad Bufo bufo L. (Amphibia, Anoura)].
abstract: The formation of myosepts of the toad is characterized by three stages in early development. At the first stage, the somitic cells give off some pseudopods and many collagen fibres. At the second stage, the newwork of collagen fibers grows denser but pseudopods retract. In the end, at the third stage, the collagen fibres disappear and secreting fibroblasts are seen in the myosepts.
