Question

Quizplus · Accepted Answer

The myelin sheath is a fatty layer surrounding the axon of some neurons, and it serves to increase the speed and efficiency of the transmission of signals from one neuron to another or from a neuron to a muscle or gland. It does not receive or process information and does not function as a guard against disease. While it may help to keep the axon alive by providing insulation, that is not its primary function.
