![]() ![]() Myelin has two functions in the nerve cells. Myelin is secreted by oligodendrocytes, which insulate the axons of the nerve cells in the brain. The lipid components of the myelin give the colour to the white matter. It is mainly composed of myelinated axons of the nerve cells. The white matter occurs in the subcortical regions of the brain. ![]() ![]() The white matter is the pale coloured parts of the brain and the spinal cord. Key Terms: Axons, Brain, Cell Bodies, Grey Matter, Myelin, Nerve Cells, Neuroglia, Spinal Cord, White Matter What is the Difference Between White Matter and Grey Matter What are the Similarities Between White Matter and Grey MatterĤ. The white colour occurs due to the lipid components of the myelin. The main difference between white matter and grey matter is that white matter mainly consists of myelinated axons whereas grey matter mainly consists of cell bodies, axon terminals, and dendrites. But, grey matter is the major component of the brain. White matter occurs in both brain and the spinal cord. The major function of the central nervous system is to coordinate the functions of the body based on the information carried by the peripheral nervous system. The brain and the spinal cord consist of nerves that belong to the central nervous system. White matter and grey matter are two components in the brain and the spinal cord.
