Low myoplasmic Mg2+ potentiates calcium release during depolarization of frog skeletal muscle fibers
The role of intracellular free magnesium concentration ([Mg2+]) in modulating calcium release from the sarcoplasmic reticulum (SR) was studied in voltage-clamped frog cut skeletal muscle fibers equilibrated with cut end solutions containing two calcium indicators, fura-2 and antipyrylazo III (AP III), and various concentrations of free Mg2+ (25 microM-1 mM) obtained by adding appropriate total ...
متن کاملEffects of sulfhydryl inhibitors on depolarizations-contraction coupling in frog skeletal muscle fibers
We have studied the effects of the sulfhydryl reagents on contractile responses, using either electrically stimulated single muscle fibers or short muscle fibers that were voltage-clamped with a two-microelectrode voltage-clamp technique that allows the fiber tension in response to membrane depolarization to be recorded. The sulfhydryl inhibitors para-chloromercuribenzoic acid (PCMB) and parahy...
متن کاملThe Role of Sodium Current in the Radial Spread of Contraction in Frog Muscle Fibers
The membrane potential of isolated muscle fibers was controlled with a two-electrode voltage clamp, and the radial extent of contraction elicited by depolarizing pulses of increasing magnitude was observed microscopically. Depolarizations of the fiber surface only 1-2 mv greater than the contraction threshold produced shortening throughout the entire cross-section of the muscle fiber. The radia...
متن کاملUltraslow contractile inactivation in frog skeletal muscle fibers
After a contracture response, skeletal muscle fibers enter into a state of contractile refractoriness or inactivation. Contractile inactivation starts soon after membrane depolarization, and causes spontaneous relaxation from the contracture response. Here we demonstrate that contractile inactivation continues to develop for tens of seconds if the membrane remains in a depolarized state. We hav...
متن کاملImpedance of Frog Skeletal Muscle Fibers in Various Solutions
The linear circuit parameters of 140 muscle fibers in nine solutions are determined from phase measurements fitted with three circuit models: the disk model, in which the resistance to radial current flow is in the lumen of the tubules; the lumped model, in which the resistance is at the mouth of the tubules; and the hybrid model, in which it is in both places. The lumped model fails to fit the...
