D) the speed of neural impulses cannot be determined.

Question

Quizplus · Accepted Answer

Neural impulses do not travel anywhere near the speed of light; instead, they move at a much slower rate, which varies depending on the type of neuron and whether or not the neuron is myelinated. Speeds can range from about 1 meter per second to 100 meters per second, significantly slower than the speed of light, which is approximately 300,000 kilometers per second.
