The action potential is produced by the:
A)movement of neurotransmitters across the ion channels.
B)opening and closing of the nodes in the myelin sheath.
C)reuptake of the neurotransmitters into the vesicles.
D)movement of ions across the membrane of the axon.

Question

Quizplus · Accepted Answer

The action potential is a result of the movement of ions (specifically sodium and potassium) across the membrane of the axon, which changes the charge of the membrane and creates a nerve impulse. Neurotransmitters are involved in neuron communication, but do not directly produce the action potential. The nodes in the myelin sheath are where the action potential jumps, but they do not produce the action potential themselves. Reuptake occurs after a neurotransmitter has been released and has fulfilled its function, and is not involved in producing the action potential.
