What is the insulation called that surrounds neural connections?

Explanation:
The insulation around neural connections is the myelin sheath. It wraps around the axon, not the dendrites, and acts as electrical insulation to speed up signal transmission along the nerve fiber through saltatory conduction, where impulses jump from one gap (node of Ranvier) to the next. Myelin is produced by oligodendrocytes in the central nervous system and by Schwann cells in the peripheral nervous system. The axon is the part that conducts impulses, dendrites are the receiving branches, and the synapse is the communication gap between neurons.
