Early stage of re-innervation of frog slow muscle fibres

Short Communications and Technical Notes

Summary

Pyriformis muscles of Rana temporaria were denervated by crushing the sciatic nerve. One to three months later most slow fibres were re-innervated by motor axons with conduction velocities above 5 m/sec. Since normal slow fibres were never found to have motor axons conducting faster than 5 m/sec it is concluded that, at an early stage, slow fibres are re-innervated non-selectively by axons of the fast type.
