Question

Which of the following is the pathway that a nerve impulse travels through a neuron?

• A. Axon $\to$ cell body $\to$ dendrite
• B. Cell body $\to$ axon $\to$ dendrite
• C. Axon $\to$ myelin sheath $\to$ dendrite
• D. Dendrite $\to$ cell body $\to$ axon

Answer 1

The correct option is D Dendrite $\to$ cell body $\to$ axon

• The impulse triggers a release of chemicals that allow the impulse to travel through the synapse the space between the axon of one neuron, then to the cell body and to the dendrites of the next.
• An impulse travels along the neuron pathways as electrical charges move across each neural cell membrane.
• Nerve impulse that a nerve impulse travels through a neuron is from the dendrites then to the cell body then to the axon. Hence, Dendrite → cell body → axon is the pathway that a nerve impulse travels through a neuron

So, the correct answer is 'Dendrite → cell body → axon'.
