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.

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.
