Detailed explanation-1: -The white matter and grey matter are similar as they are both essential sections of both the brain as well as the spinal cord. [2] The grey matter gets its grey tone from a high concentration of neuronal cell bodies.
Detailed explanation-2: -Gray matter, named for its pinkish-gray color, is home to neural cell bodies, axon terminals, and dendrites, as well as all nerve synapses. This brain tissue is abundant in the cerebellum, cerebrum, and brain stem.
Detailed explanation-3: -Grey matter serves to process information in the brain. The structures within the grey matter process signals from the sensory organs or from other areas of the grey matter. This tissue directs sensory stimuli to the neurons in the central nervous system where synapses induce a response to the stimuli.
Detailed explanation-4: -The white matter is so-called because it contains many nerve fibers or neurons that are sheathed in the white fatty insulating protein called myelin. In section, myelin is white whereas the gray matter is that color due to all the gray nuclei contained in the cells that make it up.
Detailed explanation-5: -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.
