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.
This is known as the myelin sheath. Myelin sheath is formed by special cells called Schwann cells. Schwann cells wrap around the axon and form the myelin to form the myelin sheath. This is the difference between Schwann cell and myelin sheath. Schwann cells and myelin sheaths are important for the effective and efficient transmission of nerve impulses through neurons.
