    Central Nervous System Tissue

    • White matter is rich in axons, which are long slender extensions of neurons that transmit signals.
    • The white matter gets its white hue from the fatty insulating substance called myelin, which surrounds the axons.
    • Grey matter contains most of the neuronal cell bodies, which are the central part of the neuron that contains the nucleus.
