Question

Quizplus · Accepted Answer

The trigger zone of a neuron is located where the axon connects to the neuron's cell body. This is where the neuron integrates incoming signals from other neurons and decides whether or not to fire an action potential. It contains voltage-gated channels that can open in response to changes in membrane potential, leading to the initiation of an action potential.
