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 layer of lipid around an axon is called?
Myelin sheath
What is the fatty tissue that covers axons and speeds up impulses as they travel from cell to cell?
That substance is called the myelin cell or myelin sheath.
How does a myelin sheath form?
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.
What is the insulating layer wrapped around nerve cells that increases the speed of nerve impulse transmission?
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.
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
The layer of lipid around an axon is called?
Myelin sheath
What is the definition of myelin sheath?
A myelin sheath is a layer of myelin (a dielectric, or electric insulator) around the axon of a neuron.
The Schwann cell forms a myelin sheath around the?

It insulates the axon of the neuron?
An insulating layer that surrounds the axon is a myelin sheath.
What does the sheath do around the axon?
Protects the axon. The "Myelin Sheath" serves as an insulator to protect nerves.
What is myelin sheath on nerve fibers?
The endoneurium surrounds and protects the myelin sheath.
How does a myelin sheath form?
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.
What creates myelin sheath?
Oligodendrocytes are specialized neurolgical cells that produce myelin sheath.
