Gray Matter Vs White Matter

The central nervous system is composed of the brain and the spinal cord.

Gray matter vs white matter.

White matter is the whitish nerve tissue of the central nervous system that is mainly composed of myelinated nerve fibers or axons. The brain which has multi level organized neurons and connections of indefinite neurons is divided wholly into grey and white matter. 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. The nervous system is divided into two parts.

In the spinal cord things are largely reversed the white matter is distributed around the central gray matter butterfly. Grey matter vs white matter. White matter vs gray matter. White matter is mainly comprised of bundles of myelinated axons also known as tracts.

Firstly let s define white matter vs. Other gray matter structures like the basal ganglia are embedded within this white matter core. Myelin is rich in lipids and protein and it mainly functions to protect axons and convey nerve signals. These injuries affect one of the most complicated and mysterious areas of the body an area that many injury survivors knew little about prior to their accident.

A cross section of a brain will show these cells in their respective colours and they are so named as white and gray matter. White vs gray matter. Main difference white matter vs grey matter. Grey matter vs white matter in the brain about 276 000 people in the u s.

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. 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 and grey matter are two components in the brain and the spinal cord. 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.

Both white matter and gray matter are terms that relate with the cells of the brain. Currently live with spinal cord injuries with an additional 12 500 new cases every year.
