Where is white matter located quizlet?
The cerebral white matter is located deep to the cerebral cortex in both hemispheres.
What would you find in the white matter of the spinal cord quizlet?
White Matter’s function: The white matter of the spinal cord is composed of myelinated and nonmyelinated nerve fibers that allow communication between different parts of the spinal cord and between the cord and brain.
Does everyone have white matter in the brain?
“Gray matter” is only one of two types of brain tissue; the other “white matter” is rarely mentioned. Yet white matter makes up half the human brain and has not been thought to be important in cognition or learning outside the context of pathology.
What does it mean when you have white matter on a brain MRI?
White matter disease is commonly detected on brain MRI of aging individuals as white matter hyperintensities (WMH), or ‘leukoaraiosis.” Over the years it has become increasingly clear that the presence and extent of WMH is a radiographic marker of small cerebral vessel disease and an important predictor of the life- …
How does white matter affect the brain?
White matter is tissue in the brain composed of nerve fibers. The fibers (called axons) connect nerve cells and are covered by myelin (a type of fat). The myelin is what gives white matter its white color. Myelin speeds up the signals between the cells, enabling the brain cells to quickly send and receive messages.
Is white matter in brain bad?

What does the white matter of the spinal cord mostly contain?
White matter is one of the two components of the central nervous system. It consists mostly of glial cells and myelinated axons and forms the bulk of the deep parts of the brain and the superficial parts of the spinal cord.
What are the three funiculi of white matter found in the spinal cord?
The horns of gray matter divide the white matter into three columns (funiculi): dorsal, lateral and ventral.
