Abstract
The membrane constants of the EDL and SOL muscle fibers of the rat were measured by' square pulse analysis'. The transverse resistance of the fiber membrane at 27°C is about 540Ωcm2 for both muscles and the membrane capacitance is about 6μF/cm2 for the EDL and 4μF/cm2 for the SOL. Functional significance of the difference in the membrane capacitance between the two muscles has been discussed.
