Myelination Increases AP Conduction Velocity By

Question

Myelination increases AP conduction velocity by: A)Increasing the axonal diameter. B)Increasing membrane capacitance. C)Limiting voltage-gated K⁺ channels to the nodes. D)Decreasing the membrane resistance. E)Increasing the length constant and decreasing the membrane capacitance between the nodes.

Accepted Answer

Myelination increases the length constant and decreases membrane capacitance between the nodes, allowing faster action potential propagation by saltatory conduction.
