Grey matter is distinguished from white matter in that it contains numerous cell bodies and relatively few myelinated axons, while white matter contains relatively few cell bodies and is composed chiefly of long-range myelinated axons. The colour difference arises mainly from the whiteness of myelin. 2021-02-24 · White matter is the brain’s “wiring system” that connects the cells within the gray matter to each other. When the white matter experience changes or does not regenerate properly, it cannot transmit messages to the gray matter’s cell bodies, and information such as muscle movements and memory recall cannot be processed. Gray matter, which is gray in preserved tissue but pink or light brown in living tissue, contains a relatively high proportion of neuron cell bodies. Conversely, white matter is composed mainly of axons and is named because of the color of the fatty insulation called myelin that coats many axons.
