Which of the following neuron locations have the greatest density of voltage-gated Na⁺ channels, thus resulting in the lowest threshold potential along a neuron?

Question

Quizplus · Accepted Answer

The axon hillock is located at the base of the axon and is responsible for integrating signals from the dendrites and cell body. It has the highest density of voltage-gated Na+ channels, which allows for the depolarization of the membrane and initiation of an action potential. As a result, it has the lowest threshold potential along a neuron.
