Gray Matter And White Matter Brain

Grey matter in the brain and spinal cord gray matter named for its pinkish gray color is home to neural cell bodies axon terminals and dendrites as well as all nerve synapses. The white matter is made up of neurons that have myleniated axons. For example the cerebral cortex which is the outer layer or surface structure of the brain consists of gray matter columns that have the white matter positioned under the gray matter.

Gray matter and white matter brain.

A lot of confusion revolves around the distinction between gray and white matter in the brain but the difference is actually a pretty simple one. Grey matter or gray matter is a major component of the central nervous system consisting of neuronal cell bodies neuropil dendrites and unmyelinated axons glial cells astrocytes and oligodendrocytes synapses and capillaries grey matter is distinguished from white matter in that it contains numerous cell bodies and relatively few myelinated axons while white matter contains. White matter is composed of bundles which connect various grey matter areas the locations of nerve cell bodies of the brain to each other and carry nerve impulses between neurons. Myelin acts as an insulator which allows electrical signals to jump rather than coursing through the axon increasing the speed of transmission of all nerve.

How are gray matter and white matter arranged in the cns. The arrangement of white and gray matter in the brain. Both gray and white matter are spread throughout the human central nervous system the brain and spinal cord. Gray matter location neuronal cell bodies are abundant in the cerebrum brain stem and cerebellum.

The brain contains both gray matter and white matter. Gray matter and white matter in the brain. White matter and grey matter are two components in the brain and the spinal cord. First of all the gray matter has a key role in controlling sensory and muscular activity more precisely the brain regions which predominantly contain the grey matter are involved in these processes.

Main difference white matter vs grey matter. The brain and the spinal cord consist of nerves that belong to the central nervous system the major function of the central nervous system is to coordinate the functions of the body based on the information carried by the peripheral nervous system.
