WebThe twitch force lags behind the [Ca 2+] and [TnC–Ca] transients because of the delay in stretching the series elastic elements.On repetitive stimulation by its motor neuron, the SR repetitively releases Ca 2+ and the Ca 2+ transients meld to form a more continuous high myoplasmic [Ca 2+].By simple mass action, the prolonged [Ca 2+] prolongs the time that … WebJan 17, 2024 · Frequency summation.
