[Comparative histology, histochemistry and innervation of the striated muscle fibers of the peroneus longus muscle].
The morphology of the peroneus longus muscle was compared in three Galliformes and five Passeriformes in relation to partial behavioral characteristics. In the quail two fibre types are found, while the muscle of the other species is composed of three fibre types. The frequencies of these fibres are different, especially between Galliformes and Passeriformes. The peroneus longus muscle in the quail is innervated only from the phasic system. The other species show phasic and tonic innervation. There is a correlation between the muscle fibre calibre and the extent of the synaptic gutter.
