PATHOLOGY

Detailed explanation-1: -Unlike the structure of the spinal cord, the grey matter in the brain is present in the outermost layer. The grey matter surrounding the cerebrum is known as the cortex of the brain. There are two major cortexes in the brain, the cerebral cortex and the cerebellar cortex.

Detailed explanation-2: -White matter is found buried in the inner layer of the brain’s cortex, while the grey matter is mainly located on the surface of the brain. The spinal cord is arranged in the opposite way, with grey matter found deep inside its core and the insulating white matter wrapped around the outside.

Detailed explanation-3: -The cerebral cortex is the outside portion of the cerebrum, also called the “gray matter”. It generates the most complex intellectual thoughts and controls body movement. The cerebrum is divided into left and right sides, which communicate with each other through a thin stalk of nerve fibers.
