Step 1 Introduction on White matter and grey matter of brain:

The white matter in the spinal cord is also referred to as a superficial tissue because it is located in the outer peripheral regions of the brain and spinal cord whereas grey matter is located nearer to the center of the central nervous system. The grey matter is associated with the central nervous system with respective to its functions like cognition, initiating brain signals that travel down the spinal cord and into the body, and processing of nervous system signals. White matter derives its white appearance from myelin, that coats around the axons.
