Gray Matter

← Back

Gray Matter (or Grey Matter) consists of neuronal cell bodies, dendrites, axons, glial cells, synapses, and capillaries and is a major component of the central nervous system–it is present in the brain, brain stem, cerebellum, and spinal cord.

Gray matter contains abundant cell bodies and few myelinated axons. In living tissue, gray matter has a grayish-pink coloring.

Gray matter’s job is to process information generated in the sensory organs and other areas of gray matter. It plays a part in muscle control and sensory perception (hearing, seeing, memory, emotions, speech, decision making and self-control)
