Which statement about the speed of neural impulses is TRUE?

Question

Quizplus · Accepted Answer

The speed of neural impulses can vary, but they can travel as fast as 200 miles per hour in some neurons. However, this speed is not universal to all neurons.

Answer: C
 Impulses can travel faster if an axon is encased in myelin, which acts as an insulator, allowing the impulse to jump across the gaps between the myelin sheaths. Therefore, impulses actually travel slower in unmyelinated axons.

Note: D is not a true statement as the speed of neural impulses is determined by the properties of the axon and not by the intensity of the stimulus.
