The central area of the spinal cord is gray matter, and the outer surface of much of the brain consist of gray matter called cortex. (Anatomy and Physiology, Seeley Stephens Tate, 2008, p. 382)

The grey matter on a spinal cord is on the spinal roots.
It is the area between the pia matter and the arachnoid membrane of the brain. The pia matter is part of the membrane that surrounds the brain and spinal cord. The arachnoid membrane is the inner layer of three layers that surround the brain and spinal cord.
There are two tissues that makes up the brain and the spinal cord. These are called the grey matter and the white matter. Grey matter is what covers about a half an inch of the brain. White matter is what makes up everything else of the brain.
grey and white. White matter of the spinal cord is composed of myelinated and unmyelinated fibers that allow communication between different parts of the spinal cord and between the cord and brain. Gray matter in the spinal cord looks like the letter H or a butterfly.
Gray matter and white matter are essentially the same in the brain and spinal cord. The gray matter is the part of the brain and spinal cord that initiate the firing of neurons and the white matter is basically the mode of transportation for the signal.
You can have and you have the reflex arc situated spinal cord level. The function of the reflex arc can not be overemphasized. This reflex withdrawal from the harmful stimulus protects you to great extent. Secondly the spinal cord is well placed away from the brain. So that the arrangement of nerves in your brain becomes less complicated.

Motor neurons are located in the gray matter of the brain, and their axons stretch out to the spinal cord through the ventral root. they are located in the Ventral horn of the spinal cord,
The brain is superior to the spinal cord.
The pia mater is the innermost layer of the meninges that surrounds the brain and spinal cord. Its function is to provide a protective covering for these structures and to help support and nourish the central nervous system through its rich blood supply.
The brain stem connects the brain to the spinal cord, so that the brain can send messages through the cord to the rest of the body. The functioning of the body is severely compromised if the spinal cord connections are severed.
