This report was based on the experiments of prof. C. over m. gastrocnemius in a frog, innervated, as is known, by two roots. The very fact of such double innervation makes one think that in m. gastrocnemius has 2 parts, innervated apart from each other. However, another explanation is possible, namely that each fiber of a given muscle is innervated from two sources.</p>Kazan Medical archiveКазанский медицинский архив
