The myelin sheath wraps around the around the axon of a neuron. The gaps of the myelin sheath are not insulated and are therefore capable of generating electrical activity.
The sheath that covers an axon is called myelin sheath or medullated sheath which is externally covered by neurilemma.
Myalin sheath is composed of different types of insulating neuroglial cells. There are microglial cells and macroglial cells.
it found in the axons.

Myelin sheath
That substance is called the myelin cell or myelin sheath.
The myelin sheath is an extruded plasma membrane wrapped in a spiral fashion around a nerve axon. The myelin membranes are part of the Schwann cells of the peripheral nervous system.
The myelin sheath. Due to its insulating properties, the myelin sheath prevents the movement of ions in nerve cells. Therefore nervous impulses will jump between the gaps in the myelin sheath (called the Nodes of Ranvier). This is a lot quicker than the conduction in non-myelinated nerve fibres which occurs by the movement of ions across each of the nerve cell membranes.
Myelin sheaths insulate nerve fibers
Myelin sheath
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.

An insulating layer that surrounds the axon is a myelin sheath.
Protects the axon. The "Myelin Sheath" serves as an insulator to protect nerves.
The endoneurium surrounds and protects the myelin sheath.
The myelin sheath is an extruded plasma membrane wrapped in a spiral fashion around a nerve axon. The myelin membranes are part of the Schwann cells of the peripheral nervous system.
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.
