Final answer:

The myelin sheath is a crucial insulating layer that enhances the speed of nerve impulse transmission along axons.


Explanation:

Myelin sheath is a fatty substance that covers the axon of many neurons, acting as an insulator and allowing faster transmission of electrical signals. It is produced by glial cells and contains nodes of Ranvier, which facilitate rapid nerve impulse conduction.
