At what region of the neuron are action potentials first produced?
A)dendrites
B)cell body
C)initial segment of an axon
D)axon hillock

Question

Quizplus · Accepted Answer

Action potentials are first produced at the initial segment of an axon, where a threshold stimulus is usually required to trigger the depolarization of the membrane and the subsequent generation of an action potential. The dendrites and cell body receive incoming signals, but do not produce action potentials themselves. The axon hillock is where the initial segment of the axon usually begins and is a common location for the generation of action potentials.
