Namely, the gray matter contains glial cells, axon tracts, neuropil (glia, dendrites, and unmyelinated axons), as well as capillary blood vessels (1). The white matter contains the glial cells responsible for the production of myelin (the oligodendrocytes) and the astrocytes (1).Oct 16, 2019

Many of these nerve fibers are surrounded by a type of sheath or covering called myelin. ... It contains the cell bodies of neurons, which give gray matter its color.Jan 28, 2021
Why is GREY and white matter important?
The gray matter is the areas where the actual "processing" is done whereas the white matter provides the communication between different gray matter areas and between the gray matter and the rest of the body. The neurons in the gray matter consist of neuronal cell bodies and their dendrites.
