Detailed explanation-1: -Axons are the processes that extend from neuronal cell bodies, carrying signals between those bodies. 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.
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. It also forms a butterfly-shaped portion of the central spinal cord.
Detailed explanation-3: -Gray matter refers to tissue which is made up of nonmyelinated neurons, while white matter refers to areas of myelinated neurons.
