You won't believe these 10 facts about people. Gray matter or grey matter is a type of neural tissue which is found in the brain and spinal cord. It is named after its distinctive brownish-gray color, in contrast with white matter, another type of neural tissue which appears white because it is coated in myelin sheathes.
Within the gray matter are interneurons with which the sensory neurons may connect. Also located in the gray matter are the motor neurons whose axons travel out of the cord through the ventral root. The white matter surrounds the gray matter. It contains the spinal tracts which ascend and descend the spinal cord.
