Describe the specific functions of the glial cells found in the white and gray matter on the slide. how do they differ from what might be seen in the peripheral nervous system?

Glial cells in the white matter help promote communication between the nerve impulses in the gray matter. They differ because in the peripheral nervous system there is more of a fatty substance that acts as a cushion between the impulses, which is a little different than helping the nerve impulses along intentionally. The cushioning may aid in transmission indirectly, but serves as more of a safety zone.
