Explanation:
Detailed explanation-1: -White matter is found in the deeper tissues of the brain (subcortical). It contains nerve fibers (axons), which are extensions of nerve cells (neurons). Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. Myelin gives the white matter its color.
Detailed explanation-2: -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.
