For an action potential to be transmitted to the next neuron, it must first be ______ at the axon hillock.

Question

Quizplus · Accepted Answer

An action potential is generated at the axon hillock when the membrane potential reaches a threshold level. This triggers the opening of voltage-gated ion channels and the propagation of an electrical signal down the axon. Diluting or retracting the action potential would not allow it to reach the next neuron, and reversing it would involve an unnatural reversal of ion flow that would not occur in a normal physiological process.
