Answer:
What is gray matter?
Gray matter consists primarily of neuronal cell bodies, or soma. This a spherical structure that houses the neuron’s nucleus.
What is white matter?
White matter areas of the brain mainly consist of myelinated axons, which are long relays that extend out from the soma, and which are whiteish in color due to the relatively high lipid fat content of the myelin protein that sheathes them, These form connections between brain cells, and white matter is typically distributed into bundles called tracts.
Is it really that simple?
Not quite. While the above division is physiologically accurate on a system level, there are a mix of cell types present in both gray and white matter.
Gray matter also contains:
Axon tracts
Glial cells
Capillary blood vessels
Neuropil – a mix of dendrites, unmyelinated axons, and glia
White matter also contains:
Oligodendrocytes – glial cells which produce myelin
Astrocytes
