Which structure conducts electrical impulses away from the cell body?

Which structure conducts electrical impulses away from the cell body?

• A. Dendrites
• B. Soma
• C. Axon
• D. Interneuron

Answer: (C)

Electrical signals travel from the cell body along a long projection to reach other neurons or effectors. Dendrites receive signals and conduct them toward the cell body, while the soma serves as the metabolic center that integrates inputs. An interneuron is a type of neuron, not a specific structure for conducting impulses. The axon is the structure that carries the action potential away from the soma toward synapses, and it may be insulated by myelin to speed up that transmission. Therefore, the structure that conducts impulses away from the cell body is the axon.
