Detailed explanation-1: -The central nervous system is made up of two types of tissue: the grey matter and the white matter. The grey matter is mainly composed of neuronal cell bodies and unmyelinated axons. Axons are the processes that extend from neuronal cell bodies, carrying signals between those bodies.
Detailed explanation-2: -Grey matter consists of neuronal cell bodies and their dendrites. The dendrites are short protrusions (like little fingers) that communicate with neurons close by. In contrast, your white matter consists of the long axons of neurons that transmit impulses to more distant regions of your brain and spinal cord.
Detailed explanation-3: -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-4: -Gray matter refers to tissue which is made up of nonmyelinated neurons, while white matter refers to areas of myelinated neurons.
