Myelinated axons conduct impulses much faster because
A) the myelin insulates the axon.
B) channels only have to open at the nodes.
C) voltage is not lost through along myelinated areas.
D) of saltatory conduction.
E) all of these answers.

Question

Quizplus · Accepted Answer

All of these answers explain why myelinated axons conduct impulses much faster. Myelin insulates the axon, allowing for less leakage of voltage, channels only have to open at the nodes which speeds up the transmission, and saltatory conduction allows for the impulse to jump from node to node, bypassing non-myelinated areas and increasing the speed of transmission.
