The action potential is directly created when ____.
A) vesicles in the axon release neurotransmitters
B) myelin is produced by the cell body
C) sodium (Na+) ions flood into the axon
D) DNA is released into the synapse

Question

Quizplus · Accepted Answer

The action potential is directly created when sodium (Na+) ions flood into the axon, causing depolarization and the propagation of an electrical signal down the axon. Vesicles releasing neurotransmitters and the production of myelin are not directly involved in the creation of an action potential, and DNA does not play a role in neural signaling.
