What is the name of the sheath that encases axons to protect them and increase the speed of communication between neurons?

The correct answer is the myelin sheath.

Myelin sheath refers to a fatty layering, which produces a protective sheath around the nerve fibers and drastically enhances the rate of transmission of nerve signals. The myelin sheath has various functions in the nervous system.

However, the prime function of it is to safeguard the nerves from other electrical impulses, and accelerating the time it consumes for a nerve to cross an axon.

Solution:

the name of the sheath that encases axons to protect them and increase the speed of communication between neurons is known as myelin sheath.

It is known as the insulating envelope of myelin that surrounds the core of a nerve fiber or axon and that facilitates the transmission of nerve impulses, formed from the cell membrane of the Schwann cell in the peripheral nervous system and from oligodendroglia cells. medullary sheath.
