central nervous system (CNS)
A group of myelinated fibers may form a region of nerve tissue called a white matter tract. White matter in the central nervous system consists of myelinated nerve fibers that transmit information between different parts of the brain and spinal cord.
a nerve fiber that lacks the fatty myelin insulating sheath. Such fibers form the gray matter of the nervous system, as distinguished from the white matter of myelinated fibers. Also called nonmedullated nerve fiber.
Non-myelinated fibers appear as thin, unmyelinated axons within bundles of nerve fibers. They lack the myelin sheath that surrounds some other nerve fibers, which gives them a more transparent or grayish appearance compared to myelinated fibers. Non-myelinated fibers are typically smaller in diameter and conduct nerve impulses more slowly than myelinated fibers.
Mylein is Fat, and is white. Answer #2 Myelin is actually a cell covering the "shaft" of a nerve axon, improving conduction across the cell as a whole. It doesn't hold stain as well, and generally appears whiter than unmyelinated cells, so they are white. Myelin isn't fat.
The gray-white matter junction in the brain is where the gray matter (composed mainly of neuron cell bodies) transitions into white matter (composed mainly of myelinated nerve fibers). This junction is found throughout the brain, reflecting the boundary between the outer cortex and the inner white matter tracts.

Yes, white matter is dense in myelinated axons. White matter in the brain and spinal cord is primarily composed of nerve fibers that are encased in myelin sheaths, which give it its white color. Myelination helps to speed up the transmission of nerve impulses along these axons.

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.
it is the substance surrounding the gray matter. It is also composed of myelinated nerve fibers and makes up nerve pathways called tracts.
In white matter, the most abundant structures are myelinated nerve fibers, which are composed of axons bundled together with their protective myelin sheaths. These nerve fibers facilitate rapid transmission of signals between different regions of the nervous system.

The white ramus communicans carries non-myelinated GVE fibers.
The white matter beneath the cerebral cortex is made up of myelinated nerve fibers that connect different regions of the brain. These fibers facilitate communication between different areas of the brain by transmitting electrical signals.
White matter in the CNS is predominantly composed of myelinated axons.
