Final answer:
The arrangement of gray and white matter in the spinal cord and the brain is similar. Gray matter consists of cell bodies and interneurons, while white matter consists of myelinated axons.
Step-by-step explanation:
The spinal cord and the brain have similar arrangements of gray and white matter. Gray matter is located on the inside and consists of cell bodies and interneurons, while white matter is on the outside and consists of myelinated axons.
In the spinal cord, the gray matter forms a butterfly-shaped region in the center, surrounded by white matter. The gray matter contains the cell bodies of motor neurons and interneurons, which are responsible for processing and integrating information. The white matter contains the axons that carry signals to and from the brain.
In the brain, the gray matter forms the outer cortex, while the white matter is located underneath. The gray matter is responsible for higher-level processing and cognition, while the white matter serves as a communication pathway, connecting different regions of the brain.
