It isn't. while there may gooey grey fleshy mass in the spine it is not THE grey matter. Our Brains and all the their mass is located inside the skull only.
The grey matter on a spinal cord is on the spinal roots.
Cartilage
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.
Neurosomas of the anterior root are located within the grey matter of the spinal cord. They consist of cell bodies of motor neurons that project their axons out of the spinal cord to innervate muscles and glands.
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.
It is still nerve tissue but it is what is called grey matter
The spinal cord is mainly white, with a grey, butterfly shaped area of grey at its center.
No, grey matter is not a disease. Grey matter refers to the part of the brain and spinal cord where nerve cell bodies are located. Alzheimer's disease, on the other hand, is a neurodegenerative disorder that affects memory and cognition.
There are two tissues that makes up the brain and the spinal cord. These are called the grey matter and the white matter. Grey matter is what covers about a half an inch of the brain. White matter is what makes up everything else of 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.
Grey matter gets its color from the darker cell bodies and capillaries in the brain and spinal cord. White matter gets its color from the myelin sheath that surrounds the nerve fibers, giving it a lighter appearance compared to grey matter.
