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 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.
The layer of lipid around an axon is called?
Myelin sheath
What insulates nerve fibers?
Myelin sheaths insulate nerve fibers
What does myelin sheath wrap around?
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.
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 is the sheath of the Schwann Cell also called?
Surrounding the myelin sheath, there is a thin membrane called neurilemmal sheath. This is also called neurilemma or sheath of Schwann. This contains Schwann cells, which have flattened and elongated nuclei. The cytoplasm is thin and modified to form the thin sheath of neurilemma enclosing the myelin sheath. One nucleus is present in each internode of the axon. The nucleus is situated between myelin sheath adn neurilemma. At the node of Ranvier (where myelin sheath is absent), the neurilemma invaginates and runs up to axolemma in the form of a finger like process. In nonmyelinated nerve fiber, the neurilemma continuously surrounds axolemma. Neurilemma is absent in central nervous system. Neurilemma is necessary for the formation of myelin sheath (myelinogeneis).
