Verified step by step guidance

Understand the structure of the spinal cord: The spinal cord is composed of two main types of tissue—gray matter and white matter. Gray matter contains neuron cell bodies and forms the butterfly-shaped core, while white matter consists of myelinated axons responsible for transmitting signals.

Visualize the arrangement: Gray matter is located centrally in the spinal cord, forming the butterfly-shaped structure. White matter surrounds this central gray matter and is located in the outer region of the spinal cord.

Clarify the function of white matter: White matter is responsible for transmitting sensory and motor signals to and from the brain. It is organized into tracts, which are bundles of axons that carry specific types of information.

Compare the options provided: The correct answer must align with the anatomical structure of the spinal cord. White matter is not evenly distributed throughout the spinal cord, nor is it limited to the dorsal horns. It surrounds the gray matter in the outer region.

Conclude based on anatomical knowledge: The correct answer is 'Surrounding the gray matter in the outer region,' as this matches the anatomical organization of the spinal cord.
