What is the main function of Schwann Cells? A. increase the speed of nerve impulses
B. improve the accuracy of nerve impulses
C. increase the strength of nerve impulses
D. communicate with other cells

A. increase the speed of nerve impulses

Explanation:

Schwann cells speed up nerve impulses by secreting a fatty substance called myelin around the axon of peripheral nerves. (Myelin can greatly increase the speed of impulses in neurons because it insulates the axon and assembles voltage-gated sodium channel clusters at discrete nodes along its length.)
