Myelin is a white, phospholipid covering that is found on axons in the body. When it comes to nerve impulses, this covering does not conduct an electric current. Instead nerve impulses "jump" from one neurofibral node to another speeding up conduction of the impulse.

What insulates nerve fibers?

Myelin insulation insulates nerve fibers by wrapping around them and forming a protective sheath. This myelin sheath helps to increase the speed of nerve impulse conduction along the nerve fibers.

Does myelin sheaths slow down nerve impluses?

No, myelin sheaths actually speed up nerve impulses by increasing the speed of signal transmission along the nerve fibers. This is due to the insulation effect of myelin, which helps to prevent signal loss or leakage.

What is the function of the myelin sheath and how does it identify the function of the myelin sheath?

The myelin sheath is a protective covering around nerve fibers that helps speed up the transmission of electrical signals in the nervous system. It acts like insulation on a wire, allowing signals to travel faster and more efficiently. The function of the myelin sheath is to enhance the speed and efficiency of nerve signal transmission.


The speed at which a neural impulse travels is increased when the axon is encased by an?

insulating layer called myelin sheath. This myelin sheath helps to speed up the conduction of electrical impulses along the axon by allowing the impulse to jump between nodes of Ranvier, known as saltatory conduction.


Which structure is coated with myelin to increase speed of nerve impulse transmission?

The structure coated with myelin to increase the speed of nerve impulse transmission is the axon. Myelin is a fatty substance that forms a protective sheath around the axon, facilitating faster electrical signal conduction through a process called saltatory conduction. This allows the nerve impulses to jump between the gaps in the myelin sheath, known as nodes of Ranvier, significantly enhancing transmission speed.


What effect will the destruction of myelin have on the signalling capability of a neuron?

I think that with the destruction of myelin (produced by Oligodendrites in the CNS or the Schwann cells in the PNS that are glial cells that speed up the signal), the signal will be slower or even lost.
