Which of the following statements is INCORRECT concerning contractile fibers? a. When a contractile fiber reaches threshold, voltage – gated fast sodium channels open allowing a rapid influx of sodium which produces a rapid depolarization which ends after several milliseconds. b. During plateau, depolarization is maintained because potassium inflow balances sodium outflow. c. Repolarization involves outflow of potassium restores the resting membrane potential to -90mV. d. During the refractory period a second contraction cannot be triggered.
