D)to synthesize neurotransmitters

Question

Quizplus · Accepted Answer

The myelin sheath is a fatty layer wrapped around some axons in the nervous system. It acts as an insulator, helping to speed up the neural impulse by allowing for saltatory conduction—a process by which the impulse jumps between gaps in the myelin sheath, rather than traveling the entire length of the axon. This makes the impulse much faster, allowing for more efficient communication between neurons.
