What type of brain tissue contains the cell bodies of neurons?

The type of brain tissue that contains the cell bodies of neurons is grey matter. Grey matter is characterized by its darker appearance compared to white matter, which is primarily composed of myelinated axons. The grey matter houses the neuronal cell bodies, dendrites, unmyelinated axons, and supporting glial cells, making it essential for processing and integrating information within the central nervous system.

In contrast, white matter is mainly involved in the transmission of signals between different areas of the brain and spinal cord, as it consists mostly of myelinated axons facilitating communication. Neuroglia refers to the supportive cells in the nervous system that maintain homeostasis, form myelin, and provide support and protection for neurons, but they do not represent the cell bodies themselves. Myelin is a fatty substance that wraps around axons in order to increase the speed of signal transmission and is integral to white matter structure.
