An insulating layer that surrounds the axon is a myelin sheath.
The endoneurium surrounds and protects the myelin sheath.
Myelin sheath
myelin sheath.
Neural impulses (action potentials) are transmitted through axons which are covered in a myelin sheath for insulation.
The white lipid material that insulates the axon of a neuron is called myelin. In the central nervous system, myelin is created by oligodendrocytes while in the peripheral nervous system the myelin is created by Schwann cells. The purpose of myelin is to speed up action potentials. It's important to know that the myelin does not coat the axon entirely; each sheath of myelin is separated by a gap, called a node of Ranvier. These gaps are responsible for the quick transport of action potentials, due to the fact that the potentials can "jump" from node to node rather than having to travel down the entire length of the axon (this is called saltatory conduction).

Myelin sheath
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.

The myelin sheath. Due to its insulating properties, the myelin sheath prevents the movement of ions in nerve cells. Therefore nervous impulses will jump between the gaps in the myelin sheath (called the Nodes of Ranvier). This is a lot quicker than the conduction in non-myelinated nerve fibres which occurs by the movement of ions across each of the nerve cell membranes.
