The potential of a neuron is at approximately +55 mV. Which of the following terms describes this state?

Question

Quizplus · Accepted Answer

This state is described as the threshold for an action potential to occur. The potential reaches approximately +55 mV, which triggers the opening of voltage-gated ion channels, allowing an influx of sodium ions and an efflux of potassium ions, resulting in a rapid depolarization and generation of an action potential. Resting potential typically ranges between -70 and -80 mV, hyperpolarization is when the potential becomes more negative than the resting potential, usually due to an increased efflux of potassium ions, and polarization refers to the separation of electrical charges across the neuronal membrane.
