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 is a covering of the neuron (nerve cell) made by schwann cells wrapping themselves around the neuron down the length of the axon.he main purpose of the myelin sheath is to speed up the conduction velocity of nerve impulses. While there is an electrical charge involved in signals along nerves, it's not the same as a current along a wire. Instead, small channels in the membrane of the neruon open up, and ions flood through.
