Verified step by step guidance

Understand the basic structure of the nervous system, which is divided into gray matter and white matter. Gray matter primarily contains neuron cell bodies, dendrites, and unmyelinated axons.

Recognize that white matter is distinct from gray matter due to its composition and function. White matter is primarily composed of myelinated axons.

Learn about myelin, a fatty substance that surrounds the axons, providing insulation and increasing the speed of electrical signal transmission along the nerve fibers.

Identify the role of white matter in the nervous system, which is to facilitate communication between different brain regions and between the brain and spinal cord.

Consider the importance of myelinated axons in the efficient functioning of the nervous system, as they enable rapid signal transmission, which is crucial for coordinated and quick responses.
