Explain how myelination affects the transmission of nerve impulses and why this process is important for the nervous system.

• Myelination increases the speed of impulse transmission, allowing faster communication within the nervous system.

• Myelination slows down impulse transmission, making communication less efficient.

• Myelination has no effect on impulse transmission.

• Myelination only affects the digestive system, not the nervous system.
