The minimum depolarization needed to open Na⁺ gates is called the A)repolarization. B)threshold. C)refractory period. D)All-or-none law.

Question

Quizplus · Accepted Answer

The correct term for the minimum depolarization needed to open Na⁺ gates is "threshold". This is the point at which the membrane potential reaches a critical value, causing the gates to open and allowing for the influx of sodium ions, leading to an action potential. The term "repolarization" refers to the restoration of the resting membrane potential after an action potential, while the "refractory period" is a period of time following an action potential during which the neuron is less responsive to input. The "All-or-none law" states that an action potential either occurs fully or not at all, but it does not refer to the minimum depolarization needed to initiate one.
