Inorganic fibers are synthetic because they are not composed of organic matter, ie, wool, hemp, cotton.
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.
White matter refers to the parts of the central nervous system that are primarily composed of myelinated nerve fibers. These fibers are responsible for transmitting information between different areas of the brain and spinal cord. White matter appears white because of the high lipid content of the myelin sheaths.
The white matter of the spinal cord appears white because it is made up of nerve fibers covered in a fatty substance called myelin. This myelin gives the nerve fibers a white color, hence the name "white matter."
Is located within the spinal cord and contains unmyelinated fibers.
