The speed of an action potential down an unmyelinated axon is best described as ____.
A) the speed of electricity, regardless of the size of the axon
B) less than 1 meter per second, regardless of the size of the axon
C) faster in thin axons than in thick ones
D) faster in thick axons than in thin ones

Question

Quizplus · Accepted Answer

The speed of an action potential down an unmyelinated axon is faster in thick axons than in thin ones due to the fact that thicker axons have a lower resistance to the flow of ions, allowing for faster conduction of the electrical signal.
