A neuron with a smaller axon diameter will transmit information faster
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -Larger diameter axons have a higher conduction velocity, which means they are able to send signals faster.

Detailed explanation-2: -An axon with a large diameter transmits an impulse faster than an axon with a smaller diameter. This is due to the fact that the larger diameter means more ions in an impulse can fit through the axon without having to squeeze past each other and therefore the ions don’t slow down.
