Verified step by step guidance

Understand the basic structure of the nervous system, which is divided into the central nervous system (CNS) and the peripheral nervous system (PNS).

Recognize that white matter is a component of the CNS, primarily found in the brain and spinal cord, and is not exclusive to the PNS.

Identify the composition of white matter, which consists mainly of myelinated axons. Myelin is a fatty substance that surrounds axons, providing insulation and increasing the speed of electrical signals.

Differentiate between white matter and gray matter. Gray matter is composed mainly of neuronal cell bodies, dendrites, and unmyelinated axons, and is involved in processing and interpreting information.

Conclude that white matter is not primarily responsible for processing sensory information; instead, it facilitates communication between different brain regions and between the brain and spinal cord.
