Web1 feb. 2024 · Electromyograms (EMGs) are a non-invasive way to determine nerve conduction velocities in the clinical setting. In one type of nerve conduction velocity … Web11 okt. 2024 · Its main function, however, is to insulate the axon and increase the velocity of action potential propagation. Myelin has properties of low capacitance and high electrical resistance which means it can act as an insulator. Therefore, myelin sheaths insulate axons to increase the speed of electrical signal conduction.
