White matter is composed mainly of myelinated axons, which are responsible for transmitting signals between different parts of the CNS. The myelin sheath, produced by oligodendrocytes, gives white matter its characteristic color.
- Myelinated Axons: These axons facilitate rapid signal transmission, allowing efficient communication between neurons. - Oligodendrocytes: These glial cells produce the myelin sheath, crucial for the high-speed conduction of electrical impulses.
