The myelin sheath is a layer of fat and protein that covers the axon of a neuron, or nerve cell.The axon, which is a long, thin projection, is designed to carry electrical signals from a neuron to other cells.he myelin sheath is a layer of fat and protein that covers the axon of a neuron, or nerve cell.
The myelin sheath acts as an insulating layer to prevent that electrical impulses from dissipating into the surrounding tissue. There are neurons without this insulating layer, and impulses travel at approx. 5m/sec. With a myelin sheath, impulses can travel upto 100 m/sec.
