How does myelination effect 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 »

What are the effects of myelination on conduction velocity?
It increases because .... Lots of fancy Latin terms here. Myelination : the wrapping of nerve axons with an insulating membrane. Conduction velocity: the speed at which impulses travel along nerves. Myelin acts as a means of preventing nerv... Read More »

In the brain, myelin coats the axons of neurons so that the electrical signals don't have to travel the whole length of the axon. Instead, the signal jumps between the Schwann cells (myelin beads) and touches down only in the "Nodes of Ranv...

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...

Hello Dusty! Interesting observation; I can see where you are coming from, but the benefit of having myelin sheaths is unrelated to sodium influxes. Rather, it has more to do with its insulating powers. Allow me to explain myself. Let's tra...

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...
