Question

multiple choice question
an electric nerve impulse that travels through a neuron when some \trigger\ changes the neurons charge from negative to positive is a(n)

○ dendrite.

○ resting state.

○ terminal button.

○ action potential.

Explanation:

• Dendrite: A part of a neuron that receives signals, not the impulse itself.
• Resting state: The neuron's state before being triggered, with a negative charge, not the impulse.
• Terminal button: Releases neurotransmitters, not the electric nerve impulse.
• Action potential: Defined as the electric nerve impulse that occurs when a neuron's charge changes from negative to positive due to a trigger.

Answer:

D. action potential
