Myelination is a term in anatomy that is defined as the process of forming a myelin sheath around a nerve to allow nerve impulses to move more quickly. An example of myelination is the formation of myelin around the axons of the body.

Glial cells (called oligodendrocytes in the central nervous system and Schwann cells in the peripheral nervous system) produce an insulating material called myelin which wraps around nerve axons.
