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.
Myelinated nerves have a special type of cell wrapped around them called Schwann cells; unmyelinated nerves are not wrapped in Schwann cells. The Schwann cells increase the speed at which impulses travel along the axon, thus making myelinated nerves much faster at transmitting information than unmyelinated nerves.
