Where are the sodium channels that trigger an action potential located?
A)axon hillock

C)axon terminal
D)axon cell body

Question

Quizplus · Accepted Answer

The sodium channels that trigger an action potential are mainly located at the axon hillock, which is the site of action potential initiation. This is because the axon hillock has a high concentration of voltage-gated sodium channels that can depolarize the membrane potential and initiate an action potential. Sodium channels are also present throughout the axon, but they are not involved in triggering the action potential.
