Myelin around axons:
A) speeds up transmission of information.
B) slows down transmission as if by an insulator.
C) has no effect on speed of transmission but acts as a protective coat on the fragile axon.
D) has no effect on speed of transmission but allows the cell access to nutrition.

Question

Quizplus · Accepted Answer

Myelin acts as an insulator and speeds up the transmission of information along the axon. The myelin sheath prevents electrical signals from becoming weaker as they move along the axon, allowing them to travel faster and more efficiently.
