Verified step by step guidance

Understand the structure of the brain: The central white matter lies beneath the cerebral cortex, which is the outermost layer of the brain responsible for higher-order functions like thought and decision-making.

Recall the composition of white matter: White matter is primarily composed of myelinated axons, which are extensions of neurons covered by a fatty substance called myelin. This myelin sheath helps in the rapid transmission of electrical signals between different parts of the brain and spinal cord.

Differentiate white matter from other components: Cerebrospinal fluid (CSF) is a clear fluid that surrounds the brain and spinal cord, providing cushioning and nutrients. Neuron cell bodies are found in gray matter, not white matter. Meninges are protective layers surrounding the brain and spinal cord, not part of the white matter.

Focus on the correct answer: Myelinated axons are the defining feature of white matter, as they facilitate communication between different regions of the brain and between the brain and spinal cord.

Conclude by reinforcing the concept: The central white matter is essential for efficient neural communication and is distinct from gray matter, cerebrospinal fluid, and meninges in both structure and function.
