Excitation-contraction coupling in crab muscle fibers was studied in voltage-clamp conditions. Extracellular calcium is essential for the mechanical activity. Two calcium influxes induced by membrane depolarization contribute to tension development: one is the inward calcium current responsible for the phasic tension, the other is a calcium influx dependent on extracellular sodium and calcium concentrations and is responsible for the tonic tension. These calcium influxes are not sufficient to… CONTINUE READING
