A neuron firing an action potential is most like a person ____.
A) driving a car
B) playing basketball
C) turning on a light
D) running down the road

Question

Quizplus · Accepted Answer

Turning on a light is an appropriate analogy for a neuron firing an action potential because neurons use electrical signals, much like the electricity that powers a light bulb. When a neuron fires an action potential, it sends a brief electrical impulse down its axon, which causes the release of neurotransmitters that then activate other neurons or cells. This is analogous to flipping a switch to turn on a light, which sends an electrical current through the wires to activate the bulb. Choices A, B, and D all involve more complex movements or actions that would not be directly comparable to the simple electrical spike of an action potential.
