Quizplus · Accepted Answer

Stimulation of a receptor typically causes the opening of channels that allow for the influx of ions such as sodium, leading to depolarization of the membrane potential and subsequent transmission of signals. Calcium and chloride ions may also be involved in some cases, but potassium and iron ions are less likely to be involved in the initial response.
