what is the function of neural mylenantion?

Answer 1

Basically it acts as an insulator for nerve conduction. This helps maintain charge strength and speed. The signal travels fast along the mylenated area and then picks up strength at nodes where there is no mylenation.

Answer 2

Most posters got some of it right. Myelin is a fatty substance around some nerves. Speed of conduction of an axon is determined by different things including if it is myelinated, and the diameter of the axon. Myelin has along its path nodes of Ranvier. the action potential can jump from node to node greatly increasing the speed of conduction of the action potential in a process called saltatory conduction. Myelin also does insulate nerves from each other. Myelin is why the white matter of the brain and spinal cord is the color white. Unmyelinated nerve fibers are gray.

Answer 3

As above, it's main function is insulating one axon from the next. Imagine lying two naked electrical wires adjacent to and touching one another. If you put current through one, the neighbor is likely to get some charge going through. The neural connections in the brain need to be orderly and precise in order for the brain to function appropriately.

Answer 4

Myelin sheath that surrounds neuron's axon has the following fuctions :
1. Facilitates the conducation of the AP (action potential) throughout the neuron.
2. protects the axon.

Answer 5

The myelin sheath is the coating of the axon of a neurone. It is primarily protective.

Answer 6

myelination of a neurone improves the conductancy of that neurone

Answer 7

Isolation of nerve impulses.
