Verified step by step guidance

Step 1: Understand the structure of a neuron. A neuron consists of dendrites, a cell body (soma), and an axon. Dendrites receive signals, the cell body processes them, and the axon transmits signals to other neurons or effectors.

Step 2: Learn the distinction between white matter and gray matter in the central nervous system. White matter primarily consists of myelinated axons, which are responsible for transmitting signals over long distances. Gray matter contains cell bodies, dendrites, and unmyelinated axons, which are involved in processing information.

Step 3: Analyze the options provided. Dendrites and cell bodies are components of gray matter, as they are involved in processing signals. Nuclei refer to clusters of neuron cell bodies in the central nervous system, also part of gray matter.

Step 4: Recognize that axons, especially myelinated ones, are the primary component of white matter. Their myelin sheath gives white matter its characteristic color and facilitates rapid signal transmission.

Step 5: Conclude that the correct answer is 'Axons,' as they are the part of the neuron primarily found in the white matter of the central nervous system.
