Question

Quizplus · Accepted Answer

The sheaths wrapped around nerve fibers of the peripheral nervous system can be either myelinated or unmyelinated. Myelin is a fatty substance that wraps around certain nerve fibers, speeding up the transmission of signals. Unmyelinated fibers lack this myelin sheath and have a slower conduction velocity. Thus, A) myelinated or unmyelinated is the best choice.
