What is the function of the myelin sheath? Do all axons present a myelin sheath?

The function of the myelin sheath is to get better the safety and speed of the neural impulse transmission with the axon. The myelin sheath serves as an electrical insulator stop the dispersion of the impulse to other adjacent structures. As the myelin sheath has gaps called Ranviers' nodes in its length, the neural impulse "jumps" from one node to another therefore increasing the speed of the neural transmission.
