Web1 The smooth muscle cell experiences an increase in intracellular Ca2+. This can come from the sarcoplasmic reticulum or from extracellular stores in response to an action potential, or a chemical signal (like a hormone) that does not require an action potential. If the signal is an action potential, we see voltage gated calcium channels WebDepolarization means the difference in charge between the inside and outside of the muscle is reduced. A different type of sodium channel, which is activated in response to depolarization, lets more sodium in and the wave of excitation spreads throughout the …
