How Would the Movement of a Nerve Impulse Be Described

Question

How would the movement of a nerve impulse be described?
A) the change in the magnetic field along a neuron
B) the passage of ions through the membrane of a neuron
C) the movement of tiny filaments inside a neuron
D) the change in a neuron so that the inside becomes more negatively charged

Accepted Answer

The movement of a nerve impulse involves the passage of ions through the membrane of a neuron. Specifically, sodium ions rush into the cell as the membrane depolarizes, creating an action potential that travels down the neuron. This impulse then triggers the release of neurotransmitters at the synapse, allowing the impulse to be transmitted to the next neuron or target cell.
