White matter in the spinal cord makes up the external portion, and is myelinated. It is partitioned into three funiculus: posterior funiculus lies between the grey horns of the posterior side of the cord and the posterior median sulcus.
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?
Almost one half of the brain’s volume is not gray but white matter, the densely packed collection of myelinated (insulated) projections of neurons that course between widely dispersed gray matter areas.
How serious is white matter disease?
Summary: More evidence has been accumulated that damage to cognitive areas is widespread from white matter disease. White matter disease is responsible for about a fifth of all strokes worldwide, more than doubles the future risk of stroke, and is a contributing factor in up to 45% of dementias.
What is white matter and what role does it play in the brain quizlet?
White matter in brain is known as the cerebral white matter. The white matter deep to the cortical gray matter is responsible for communication between cerebral areas and between the cerebral cortex and lower CNS.
What is found in the gray matter of the spinal cord quizlet?
Define gray matter in the spinal cord. It is neural tissue that is dominated by the cell bodies of neurons, neuroglia, and unmyelinated axons, and it surrounds the narrow central canal. It is neural tissue that contains large numbers of myelinated and unmyelinated axons.
What is the gray and white matter of the spinal cord quizlet?
White matter is the outermost part of the spine, mylineated. Gray matter is in the center of the spine, and it looks like the shape of a butterfly. Do meninges cover the brain and spinal cord?
What are the three Funiculi of white matter found in the spinal cord quizlet?
The lateral sades make up the lateral funiculus, and the anterior white matter makes up the anterior funiculus and anterior median fissure; the anterior funiculi are interconnected by the white commissure.
