Question

multiple choice question
action potentials in one portion of the membrane can trigger a chain reaction of action potentials in the next portions of the membrane leading to what?
o nerve signal
o threshold
o neurotransmitter release
o retrograde flow

Explanation:

Action potentials are electrical signals in neurons. A chain reaction of action potentials along the membrane of a neuron is what constitutes a nerve signal. A threshold is the level of stimulus needed to trigger an action potential, not the result of a chain - reaction of action potentials. Neurotransmitter release is a process that occurs at the end of a neuron (synaptic terminal) in response to an action potential arriving there, but it is not the chain - reaction itself. Retrograde flow is a term more related to the movement of substances within a cell (e.g., in axonal transport) in the opposite direction of the usual flow and is not related to the chain - reaction of action potentials.

Answer:

nerve signal
