Question

an electric nerve impulse that travels through a neuron when some trigger changes the neuron’s charge from negative to positive is a(n)
action potential.
terminal button.
resting state.
dendrite.

Explanation:

To solve this, we analyze each option:

• Action potential: Defined as the electrical nerve impulse that occurs when a neuron's charge changes from negative (resting state) to positive, matching the description.
• Terminal button: Involved in neurotransmitter release, not the impulse itself.
• Resting state: The neuron's negative charge state before the impulse, not the impulse.
• Dendrite: A neuron structure for receiving signals, not the impulse.

Answer:

A. action potential
