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 Ca2+ channels, which leads to the depolarization of smooth muscle cells. Choices A and B are not correct because they include potassium and sodium channels, which are not directly involved in the depolarization triggered by slow waves. Choice D is also not correct as Ach is a neurotransmitter that acts on receptors, but it does not directly open voltage-gated channels.
