WebApr 7, 2024 · Myelination is the sheath covering the axon of a neuron. In a myelinated nerve, the impulses hop from the nod to nod (Brown, 42). Myelination is advantageous in that it causes the conduction velocity to rise from 10 to 100 times the conduction velocity in ordinary nerves. Hence, myelination increases the conduction velocity significantly. WebNerve conduction velocity (NCV) adalah suatu prosedur yang digunakan untuk menilai kerusakan dan disfungsi saraf.
