Where do graded potentials become action potentials?
A)Dendritic spines

C)Synaptic cleft
D)Axon hillock

Question

Quizplus · Accepted Answer

Graded potentials become action potentials at the axon hillock, which is the region of the neuron that generates the action potential. This is due to the fact that the axon hillock contains a high concentration of voltage-gated ion channels that initiate the opening of voltage-gated Na+ channels in response to a strong enough depolarization.
