The movement of the action potential from axon hillock to axon terminal is known as:
A) the graded potential.
B) the refractory period.
C) the nerve impulse.
D) anterograde transport.

Question

Quizplus · Accepted Answer

The movement of the action potential along an axon is known as the nerve impulse. It travels from the axon hillock to the axon terminal, where it triggers the release of neurotransmitters. The other options are not accurate descriptions of this process: Graded potentials are small changes in membrane potential that do not reach the threshold for an action potential; the refractory period is the time during which a neuron cannot generate another action potential; anterograde transport refers to the movement of vesicles or organelles from the cell body to the axon terminal, but is not specific to the action potential.
