Slow wave depolarization triggers depolarization of smooth muscle by opening voltage-gated ________ channels. A)K⁺ B)Na⁺ C)Ca2⁺ D)Ach

Question

Quizplus · Accepted Answer

Slow wave depolarization triggers the opening of voltage-gated calcium (Ca2+) channels in smooth muscle, leading to calcium influx and subsequent contraction. Choices A and B are not correct because they do not identify the type of channel involved in smooth muscle depolarization. Choice D (Ach) is not correct because it is a neurotransmitter and not a channel.
