Effects of long-term phasic electrical stimulation on denervated soleus muscle: guinea-pig contrasted with rat.

abstract：:Using a variety of techniques, we have demonstrated the presence of at least two fibre types in Limulus median telson levator muscle. By light and electron microscopy, large (2,156 microns 2 mean cross-sectional area) fibres have A-bands of 4.1 microns, one-half I bands of 2.15 microns and Z lines less than or equal t...
