Detailed explanation-1: -The part of the brain and the spinal cord, where myelinated neurons are present in abundance is called white matter and the part where the cell body and non-myelinated neurons are present is called grey matter.

Detailed explanation-2: -In the grey matter, these axons are mainly unmyelinated, meaning they are not covered by a whitish-colored, fatty protein called myelin. The grey matter serves to process information in the brain. Structures within the grey matter process signals generated in the sensory organs or other areas of the grey matter.

Detailed explanation-3: -White matter refers to areas of the central nervous system (CNS) that are mainly made up of myelinated axons, also called tracts.

Detailed explanation-4: -Besides this group of neuronal cells, the axons of grey matter are not heavily myelinated, unlike white matter, which contains a high concentration of myelin.

Detailed explanation-5: -Overview. The tissue called “gray matter” in the brain and spinal cord is also known as substantia grisea, and is made up of cell bodies. “White matter", or substantia alba, is composed of nerve fibers.
