Usage: technical/medical; biology
Examples
- Myelinated axons conduct nerve impulses much faster than unmyelinated ones.
- The white matter of the brain consists largely of myelinated nerve fibers.
- Myelinated neurons are essential for rapid communication in the central nervous system.
- During development, many axons become myelinated to improve neural efficiency.
- Damage to myelinated fibers can result in serious neurological disorders.
