Which part of a neuron conducts impulses away from the cell body?

Explanation:
The key idea is understanding the distinct roles of neuron parts. Dendrites receive signals and bring them toward the cell body, while the soma processes those signals. The part that carries the impulse away from the cell body is the axon. It travels the electrical signal to synapses where communication with the next cell occurs. Some axons are insulated by myelin, which speeds up transmission, and gaps called nodes of Ranvier help with rapid signaling. The synapse itself is the junction where the message is passed to the next neuron or target, not the conduit that moves impulses inside the neuron.
