Relate the speed of conduction of an action potential to myelination
What will be an ideal response?
Myelination makes an excellent insulator of electrical current for neurons with myelin sheaths. The insulating effect increases the speed of conduction of action potentials. In fact, myelinated neurons conduct action potentials about 15-150 times faster than unmyelinated axons.
