The organogenetic development of the human extensor hallucis longus muscle

The organogenetic investigations on the human crural and foot musculature give only a general idea for the development of the m. extensor hallucis longus (Schomburg 1900; Bardeen 1907), but it is not possible to understand the sequence of the changes of the primordium of this muscle during its morphogenesis. To the best of our knowledge, so far no interpretation of these changes is known, although it is of great significance to the evolutionary myology. Therefore, it seemed reasonable to us to carry out an investigation on the organogenesis of the m. extensor hallucis longus from the evolutionary myology point of view, using the results of previous detailed comparative-anatomical study of the same muscle. The basis of such an investigation was well-grounded a few years ago (Kaneff 1977).
