Quizplus · Accepted Answer

The movement of positively charged ions (such as sodium and potassium ions) across the membrane of a neuron can produce an action potential, which is a brief electrical signal that travels down the length of the axon. This is the fundamental mechanism by which neurons communicate with one another. Glial cells, myelin sheaths, and interneurons are also important components of the nervous system, but they are not directly involved in the generation of action potentials.
