What is the predominant affect of stimulation of nicotinic-gated channels? A)stimulation due to outflow of K⁺ ions B)inhibition due to outflow of K⁺ ions C)stimulation due to influx of Na⁺ ions D)inhibition due to influx of Cl^- ions

Question

Quizplus · Accepted Answer

Stimulation of nicotinic-gated channels results in the influx of Na+ and K+ ions, causing depolarization and an excitatory response in the postsynaptic neuron. Option A and B are incorrect because K⁺ ions do not exist. Option D is incorrect because the influx of Cl- ions would cause hyperpolarization, which would be inhibitory.
