Most axons are covered with a protective sheath of myelin, a substance made of fats and protein, which insulates the axon. Myelinated axons conduct neuronal signals faster than do unmyelinated axons.
The myelin is the fatty substance that's present in some kind of neurons, structured as an excess of membrane that does several turns around the axon, improving the electrical transmission along the axon. So, the transmission of electrical impulses in myelinated neurons are faster and more efficient than in the other types.
Myelin Sheath is basically fat-containing cells that insulates the neurons from any electric impulses that travel along the nerves and makes sure that the impulses do not jump between close nerves

The Myelin Sheath that surrounds the axon insulates the axon but also increases the speed of the message traveling down it.
Medullary (myelin)- sheath is the covering of nerve fibres. It insulates the nerve fibre (axon) and prevents leakage of ions.
Most axons are covered with a protective sheath of myelin, a substance made of fats and protein, which insulates the axon. Myelinated axons conduct neuronal signals faster than do unmyelinated axons.
An insulating layer that surrounds the axon is a myelin sheath.
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).

Axons are coated in a fatty substance called myelin - a "myelin sheath". It insulates and protects the cell body of neurones. The myelin doesn't completely coat the axon: there are small gaps between the myelin, called the nodes of Ranvier.
