White matter
Myelinated axons in the central and peripheral nervous systems.
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.
nervous tissue
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
Axons are covered by connective tissue called endoneurium. Multiple axons are bundled together within fascicles, which are surrounded by perineurium. Finally, the entire nerve is enveloped by epineurium.
Unmyelinated tissue is substantially slower in conducting impulses along the axon. With myelinated axons, the action potential (impulse) jumps from node to node greatly increasing the speed of the impulse.

Muscles and glands are not myelinated. It is the axon of a neuron that is myelinated. The myelin forms a layer called myelin sheath that makes the nervous system function properly.

Saltatory Conduction
In the central nervous system, neuronal axons are myelinated by oligodendrocytes. In the peripheral nervous system axons are myelinated by Schwann cells.
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.
