In a neuron, which structure conducts impulses away from the cell body?

• A. Axon
• B. Dendrite
• C. Nucleus
• D. Synapse

Answer: (A)

Think about how a neuron sends signals. Dendrites are like receive lines, bringing impulses toward the cell body. The axon, on the other hand, is the long cable that carries the electrical impulse away from the cell body to other neurons, muscles, or glands. The nucleus lives in the cell body and stores genetic material, not involved in impulse conduction. The synapse is the junction where signals are transmitted to the next cell, not the path along the neuron itself. Because the task is to move impulses away from the cell body, the axon is the structure that does this.
