How does myelination affect the speed of transmission of neural impulses?

Myelination, the process of forming a myelin sheath around nerve fibers, significantly increases the speed of neural impulse transmission. This insulation allows electrical signals to jump between the gaps in the myelin, known as nodes of Ranvier, through a process called saltatory conduction. As a result, myelinated axons can transmit impulses much faster than unmyelinated axons, enhancing communication between neurons and improving overall nervous system efficiency.
