What Is Gray Matter?
Gray 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.
It contains abundant cell bodies and few myelinated axons. In living tissue, it has a grayish-pink coloring.
Its 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)
