Grey matter is a component of the central nervous system, comprising neuronal cell bodies, dendrites, and synapses. Grey matter is found in the brain and spinal cord, and it plays a crucial role in information processing, cognition, and motor control.
Grey matter is primarily involved in information processing, cognition, and voluntary muscle control. It is located on the brain’s outer layer (cerebral cortex) and within inner regions, as well as in the central part of the spinal cord.
Grey matter and white matter are distinct components of the central nervous system. Grey matter’s appearance is grey due to the presence of neuronal cell bodies and synapses. In contrast, white matter appears white because of myelinated axons.
