Verified step by step guidance1
Understand the structure of a nerve: A nerve is a bundle of fibers that transmit electrical signals between the brain, spinal cord, and other parts of the body.
Recall the components of a neuron: Neurons consist of dendrites (which receive signals), axons (which transmit signals), cell bodies (which contain the nucleus), and synapses (which are the junctions between neurons).
Focus on the function of axons: Axons are the long, thread-like structures that carry electrical impulses away from the cell body to other neurons, muscles, or glands.
Recognize that nerves are composed of axons: Nerves are bundles of axons that are organized in parallel to efficiently transmit signals over long distances.
Conclude that the correct answer is axons, as they are the structural component of nerves responsible for signal transmission.
