What is the long fibre that conducts electrical impulses away from the neuron called?

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

Answer: (A)

The key idea is neuron structure and how signals travel. The long fibre that carries electrical impulses away from the cell body is the axon. Dendrites are the branched parts that receive incoming signals, the soma (cell body) integrates those signals, and the synapse is the gap where communication with the next neuron occurs. The axon acts like a transmission line, moving the impulse along from the cell body to the terminals to reach other neurons or muscles, often faster when it’s insulated by myelin. So, the term that fits the description of a long fibre conducting impulses away from the neuron is the axon.
