White matter in the nervous system is caused when the axons in the area are myelinated. This means that the axons have a fatty protein covering to provide insulation. The myelin sheath is composed of special cells calls Schwann Cells.

What are the Ascending pathways of the central nervous system composed of?
The Ascending pathways of the central nervous system is made of "White Matter." (Vast amount of Axons coated with a sheath of Myelin)
What is the orientation of gray and white matter in the brain?
gray matter is composed of neuron cells and is concentrated in the cerebral cortex and nuclei and basal ganglia. white matter is composed ofneuron processes which form tracts connecting parts of the brain with each other and with the spinal cord.
What system does White matter refer to myelinated fibers?
central nervous system (CNS)
Is white matter dense in myelinated axons?
Yes White matter is the part of the nervous system that is dense is myelinated axons
What is the function of white mater in the spinal cord?
White and grey matter are essentially made up of bundles of nerve fibers (called neurons) that convey nerve impulses between the peripheral nervous system and the central nervous system. The major difference between white and gray matter within the spinal cord is that white matter is primarily composed of myelinated nerve fibers, while the nerve fibers of gray matter are not. Myelinated nerve cells tremendously increase the speed at which the action potential (nerve impulse) moves along the neurons axon. The job of the neurons that make up white matter is to either convey an action potential from a sensory receptor to the central nervous system, or, from the central nervous system out to an effector (such as a muscle or tissue). These neurons are called sensory neurons and motor neurons respectively. Gray matter consists of unmyelinated neurons, called interneurons. Their main duty is to provide communication between the peripheral and central nervous systems. Think of interneurons as a bridge linking two regions together. For unmyelinated neurons, the speed at which an action potential can propagate down the cell's axon is far less than that of the myelinated neurons of white matter.
What is myelinated nervous tissue?
White matter
What are clusters of gray and white matter containing cell bodies called in the central nervous system?
A Nucleus
What are the major divisions of the the central nervous system?
Central & Peripheral Edit: I don't think the last person read the entire question. Central (CNS) and Peripheral (PNS) are the two major divisions of the nervous system but the question is asking specifically about the central. Two major division of the central nervous system (structurally) are White matter and Gray matter.
What does a buildup of N-acetylaspartic acid do?
This results in the destruction of the white matter of the brain and nervous system and causes the symptoms of Canavan disease
Does juggling make you smarter?
The popular trick strengthens brain's white matter through which messages pass within the nervous system.

What is the gray-white matter junction in the brain?
Gray matter contains most of the neuronal cell bodies in the brain, and involves muscle control and the senses. White matter transfers the messages between different areas of the central nervous system.
