Which of the following influence(s) the speed of an action potential? a. the presence of a myelin sheath b. the extent of depolarization that initiates the action potential c. the diameter of the axon d. both the presence of a myelin sheath and the diameter of the axon
The rate of propagation of an action potential depends on a. whether or not the axon is myelinated. $b$. the axon's diameter. $c .$ whether or not the axon is insulated by glial cells. $d$. the cross-sectional area of the axon. $e .$ All of the above
Myelination increases the velocity of action potential propagation along an axon. What is myelination? Myelination causes clustering of voltage-gated $\mathrm{Na}^{+}$ channels and $\mathrm{Na}^{+} / \mathrm{K}^{+}$ pumps at nodes of Ranvier along the axon. Predict the consequences to action potential propagation of increasing the spacing between nodes of Ranvier by a factor of 10
