How can propagation speed be increased for a neuron?
A) wrapping myelin layers around the axon
B) increasing the number of neurons activated
C) increasing the amplitude of the action potential
D) removing the myelin layers around the axon

Question

Quizplus · Accepted Answer

Wrapping myelin layers around the axon can significantly increase the propagation speed of a neuron. Myelin acts as an insulator and helps to prevent signal loss or leakage as the electrical impulse travels down the axon. This allows the signal to be transmitted at a faster rate. Increasing the number of neurons activated or the amplitude of the action potential may increase the strength or intensity of the signal, but does not necessarily increase the speed at which it travels. Removing the myelin layers would actually slow down the propagation speed of the neuron.
