Because it contains a lot of axons with their fatty myelin sheaths. The fat is white.

Where are myelinated neurons especially abundant?
white matter in the brain and the white matter in the spinal cord.
Some of brain structures consist of gray or white matter what are they?
White matter is found in the inside of the brain and the spinal cord. Grey matter is found in most parts of the brain including the cerebellum and brain stem.
Where are the grey and white matter located in the brain?
To oversimplify it significantly with an analogy, the grey matter is data processing neurons and the white matter is the myelin insulated cabling axons of those neurons that interconnects them to exchange data. Myelin is fatty, giving the white color to the white matter.
A myelinated nerve fiber is characterized as being whereas an unmyelinated?
Myelinated nerves are white, and composes the white matter of the brain and spinal cord they also are able to pass an action potential down an axon much faster; Unmyelinated nerves are gray, and composes the gray matter of the brain and spinal cord. These nerves transmit signals much slower
What parts of the human body does the vertebral column protect?
spinal cord
Are motor neuron cells bodies located in the gray or white matter of the spinal cord?
the white matter
In the spinal cord which is deep to the other the white or gray matter?
in the spinal cord which is deeper to the other, the white matter or gray matter? how does this compare to the distrubution in the brain
What kind of matter do you have in your spinal cord?
grey and white. White matter of the spinal cord is composed of myelinated and unmyelinated fibers that allow communication between different parts of the spinal cord and between the cord and brain. Gray matter in the spinal cord looks like the letter H or a butterfly.
What is the difference between a horn and a column in the spinal cord?
A horn is the gray matter of the spinal cord, and a column consist of white matter.
Where does the spinal cord have gray matter?
The grey matter on a spinal cord is on the spinal roots.
What is the white matter of the spinal cord contain?
axons
Where are myelinated neurons especially abundant?
white matter in the brain and the white matter in the spinal cord.
How are gray matter and white matter switch in brain and spinal cord?
Die
What part of the spinal cord contains neurons?
Motor neurons are located in the gray matter of the brain, and their axons stretch out to the spinal cord through the ventral root. they are located in the Ventral horn of the spinal cord,
What is the different between white matter and grey matter?
grey matter- the centre area of the spinal cord that contains cell bodies, their axons and their dendrites. white matter- the outer layer of the spinal cord that contains only myelin coated axons.
The portion of the spinal cord made up of myelinated axons?
White Matter
Does The spinal cord has gray matter in the inside white matter on the outside and a ventral motor root?
yes
