WebAnswer: There are three main factors that affect the speed of nerve conduction. Action potentials propagate more rapidly along the myelinated axons than along the non-myelinated axons. Larger diameter axons propagate action potential faster than smaller ones due to their large surface area. Axon... In neuroscience, nerve conduction velocity (CV) is the speed at which an electrochemical impulse propagates down a neural pathway. Conduction velocities are affected by a wide array of factors, which include age, sex, and various medical conditions. Studies allow for better diagnoses of various neuropathies, especially demyelinating diseases as these conditions result in reduced or non-existent conduction velocities. CV is an important aspect of nerve conduction studies. Web1.
