How does myelination affect nerve conduction velocity?
Myelination will speed the nerve conduction velocity considerably. Myelin is found in Schwann cells which encircle a given axon. It acts mainly as an insulator so that depolarization in one cell does not set off depolarizations in adjoining... Read More »

This is actually easier than it may seem. I can't draw a neuron here, but you can imagine it and I'll try to explain clearly. The cell body and dendrites are at one end, then the length of the neuron, then the axon with the vesicles produci...

Simple. The charge of a nerve 'jumps' along the nodes of ranvier (parts between shcwann cells/myelination) and can therefore travel greatest distances. This is called the 'saltatory mechanism' In an unmyelinated nerve, the charge would have...

The myelin sheath serves the same purpose as the rubber insulation that covers electrical wires. If there were no myelin sheath, all the bundles of nerves touching each other would eventually short out. Multiple Sclerosis results from the b...

In myelinated nerves, the nerve impulse "skips" quickly from one unmyelinated node (nodes of ranview) to another...eliminating the need to propagate down the entire length of the axon.

For unmyelinated nerves there is a relationship between axon diameter and conduction velocity. Larger diameter nerves conduct faster. For myelinated nerves the a larger diameter nerve will conduct faster between the nodes of ranvier where t...
