In what form does a nerve impulse travel in a neuron?
Answer and explanation
Correct answer: Electrical signal
A neuron transmits information through changes in the electrical potential across its cell membrane. When sufficiently stimulated, an action potential travels along the axon as an electrical nerve impulse. At a synapse, chemical neurotransmitters may carry the message across the gap, but within the neuron the impulse is primarily electrical. Hence option A is correct; the other choices are unrelated materials, not message forms.
