What is the function of the myelin sheath that surrounds neurons?

Question

Quizplus · Accepted Answer

Increase speed of impulses. The myelin sheath serves exclusively to increase the speed at which impulses travel across neurons.
Key Takeaway: The myelin sheath increases electrical resistance across a cell membrane by a factor of 5, 000 and decreases capacitance by a factor of 50. Combined, these two factors prevent the electrical current from escaping the axon, thus improving the speed at which impulses travel.
