Grey matter refers to unmyelinated neurons and other cells of the central nervous system it is present in the brain brainstem and cerebellum and present throughout the spinal cord.
Gray matter and white matter in brain and spinal cord.
The white matter of your brain and spinal cord is composed of bundles of axons.
A transverse section of the spinal cord reveals a distinct butterfly pattern of dark inner grey matter surrounded by the lighter colour white matter.
In this video i m gonna talk about gray and white 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.
White matter s job is to conduct process and send nerve signals up and down the spinal cord.
Main difference white matter vs grey matter.
They exist in both brain and spinal cord we must emphasize one detail.
In the spinal cord things are largely reversed the white matter is distributed around the central gray matter butterfly.
At a system or classification level the division on the white and gray matter is accurate.
So most of the neuron somas in the central nervous system are found in the gray matter.
White matter and grey matter are two components in the brain and the spinal cord.
Even though both types of matter are arranged throughout our cns i e.
Other gray matter structures like the basal ganglia are embedded within this white matter core.
Such types exist both in white and gray matter.
These axons are coated with myelin a mixture of proteins and lipids that helps conduct nerve signals and protect the axons.
Grey matter is distributed at the surface of the cerebral hemispheres cerebral cortex and of the cerebellum cerebellar cortex as well as in the depths of the cerebrum thalamus.
The brain s fluid filled ventricles are also found within the white matter.
The arrangement of white and.
However there are mixed cell types.
