Resting potentials of frog sartorius muscle fibers were taken with microelectrodes at different distances along the length of muscles before and after adding acetylcholine or choline. The mean membrane potential drop and scatter of the potentials recorded in the relatively nerve-free, and in the more densely innervated parts of the muscle, were similar. The loss of direct excitability to electrical and mechanical stimulation was correlated with the concentration of choline or acetylcholine presented. d-tubocurarine added beforehand protected against the depolarizing effect of acetylcholine and choline everywhere along the length of the muscle. A generalized action of acetylcholine and choline and also of d-tubocurarine all along the muscle fibers was inferred. This generalized action at higher concentrations of acetylcholine and choline is believed to be additional to a more specific end plate action.

Sodium And Potassium

Ouabain and strophanthidin at a concentration of about 10–6 molar appear to inhibit the net transport of sodium out of and of potassium into the cells of the frog sartorius muscle under conditions where transport would otherwise occur. This inhibition occurs without significant effect on the resting potential. Dihydrostrophanthidin, also at a concentration of 10–6 m, failed to show the inhibitory action displayed by ouabain and strophanthidin.
