A neuron receives a stimulus.Which of the following events happens next?
A) A local potential develops
B) Threshold is reached
C) Hyperpolarization of the membrane
D) Repolarization of the membrane
E) A resting membrane potential is established

Question

Quizplus · Accepted Answer

When a neuron receives a stimulus, a local potential develops first. This local potential is a graded potential that reflects the magnitude of the stimulus. Only if the local potential reaches the threshold, an action potential will be generated, followed by depolarization of the membrane, repolarization, and hyperpolarization. However, the question asks for the immediate next event after the stimulus, which is the development of a local potential.
