Evidence for an action of sodium ions in the activation of contraction of twitch muscle fibre.

J Caillé, M Ildefonse, O Rougier.   

Abstract

Simultaneous records in current clamp conditions of potential and of contraction of frog skeletal twitch muscle fibre have shown that a part of the contraction directly depends on the intervention of sodium ions (increase in presence of veratrine, decrease in lithium Ringer). The results confirm previous voltage clamp data and suggest a mechanism of sodium induced calcium release.
