Question

The point at which a nerve impulse is initiated is the ____. ​
A)initiation threshold
B)initiation potential
C)action potential
D)graded potential
E)threshold potential

Quizplus · Accepted Answer

The threshold potential is the minimum membrane potential required for an action potential to occur in a neuron. It is the point at which a nerve impulse is initiated because once the threshold potential is reached, voltage-gated ion channels open, allowing an influx of positively charged ions and causing depolarization of the membrane potential, leading to the propagation of an action potential down the axon.
