Gray Matter Vs White Matter Ct

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

Gray matter vs white matter ct.

The brain consists of grey and white matter structures which are differentiated on ct by differences in density. Grey white differentiation refers to the appearance of the interface between cerebral and cerebellar white matter and grey matter on brain ct and mri. White matter and grey matter are two components in the brain and the spinal cord. Main difference white matter vs grey matter.

The ct images were then segmented to gray matter white matter cerebrospinal fluid and other compartments using an unmodified version of the clustering algorithm ashburner and friston 2000 fig. 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. 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 brain which has multi level organized neurons and connections of indefinite neurons is divided wholly into grey and white matter.

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. Other gray matter structures like the basal ganglia are embedded within this white matter core. Inability to distinguish white matter from grey matter which. As myelin is a fatty substance it is of relatively low density compared to the cellular grey matter.

Grey matter vs white matter. The central nervous system and the peripheral nervous system. The term is most often used when trying to differentiate cytotoxic from vasogenic edema. White matter is mainly comprised of bundles of myelinated axons also known as tracts.

The number of gaussians per tissue class was adjusted for each patient until successful segmentation was achieved. Myelin is rich in lipids and protein and it mainly functions to protect axons and convey nerve signals. The brain s fluid filled ventricles are also found within the white matter. Watch the next lesson.

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. White matter has a high content of myelinated axons grey matter contains relatively few axons and a higher number of cell bodies. In the spinal cord things are largely reversed the white matter is distributed around the central gray matter butterfly. Created by matthew barry jensen.
