The main cells in myelinated tracts are oligodendrocytes and astrocytes, with small populations of Water diffusion anisotropy in white and gray matter of the human spinal cord.

White matter lies beneath the gray matter and is composed of long nerve fibers insulated by myelin sheaths. Not only does myelin give white matter its distinctive color, but it also helps to speed electrical signals along nerve axons. The outside of the spinal cord is composed of large white matter tracts. Transecting or compressing these tracts can lead to paralysis because information from the brain’s motor cortex (grey matter) can no longer reach the spinal cord and muscles.
