Question

Myelin speeds the propagation of action potentials by: (indicate all that apply)
-increasing the length constant
-decreasing the length constant
-increasing the time constant
-decreasing the time constant

Answer 1

Answer:

Myelin Promotes Rapid Impulse Transmission Along Axons

How does myelin enhance the speed of action potential propagation? It insulates the axon and assembles specialized molecular structure at the nodes of Ranvier. In unmyelinated axons, the action potential travels continuously along the axons.
